An expansion joint system includes an element called a core, and a layer of elastomer disposed on the core. The core as well as the layer of elastomer placed on it make up an elongated portion which is designed to be vertically aligned between substrates that are nearly coplanar. The expansion joint system further includes a termination section located at one end of the elongated section and having a flared, rounded end which forms an angle that is elongated and that is designed to redirect fluids, particles or solvents away from the joint system.

Many joints are used in concrete structures and construction systems to support movements caused by seismic or thermal conditions. These joints can be placed to connect the exterior and interior surfaces, such as walls, floors, roofs or the the roofs of buildings or any other construction.

In the case of an exterior joint in the exterior of a wall floor, roof, and so on, that is which is exposed to the elements the joint expansion system must also resist the effects of external environmental conditions. These conditions are likely to be felt in vertical joints as rain, snow, or winds driven ice. Horizontal joints can be affected by rain, snow, or wind.

Particularly with regard the bridge expansion joints, one of the major causes of structural degradation of piers columns and beams on bridges is the leaking or deterioration of joints. De-icing salts, as well as other airborne contaminants could be put directly through expansion joints onto bridges. Possible spalling and corrosion may occur thereby necessitating expensive reconstruction of beams, piers columns, wing walls, and columns and so on.

In addition, certain expansion joint products do not fully take into consideration the irregularity of certain expansion joints. A joint that is expanded may contain multiple transition zones along its length. These may be areas like parapets, columns or other obstructions. The expansion joint follows the obstructions it encounters while moving. In many products, this is a point where the homogeneous nature of the product gets broken. The transitions can be managed by a variety of techniques that include welding, glue, and stitching. It is usually hard or even impossible to prefabricate these transitions to make expansion joints. The exact details of the expansion joints and any dimensions of any transitions are not known at the time of manufacture.

Furthermore, in a lot of products, the afore-referenced transitions present weak spots from both a water proofing aspect and a fire resistant aspect. Fire resistive and expansion joints address both the watertightness aspect. It is typical to install two systems on every expansion joint that requires both water and fire resistance. However, in many cases there is simply not enough room for both a waterproofing and fire rating system.

Accordingly, there exists a need for improved expansion joint systems, which can not only accommodate thermal and/or seismic movements, but also assist in alleviating and/or preventing deterioration of structural features due to environmentalfactors. There is also a need for such expansion joints that also address fire and water resistance in one.

These options address both the above and other needs.

An expansion joint system is described in one aspect. It comprises an inner core and a layer with elastomer. The core as well as the layer containing elastomer form an elongatedsection. The elongated part is oriented vertically among substantially coplanar substrates. The expansion joint also features a termination section on one end. It is located at the elongated section and includes an end with a flare that creates an angle with the elongatedsection. The section is designed to divert fluid, particles, and solvents away from the joint system.

Another feature of an expansion joint system: A core; and a layer of elastomer. The core and the layer of elastomer that is positioned on it create an elongated section. This section is oriented horizontally, with the coplanar substrates. It also includes an end section that slants around the corners. The extension joint also has a section for termination at the end portion that is angled around the corner. The termination section consists of an end with a flare that forms an angle with the vertically-oriented end part. It is intended to channel fluids particles, solvent, or other particles away from the expansion joint system.

According to another aspect, a water and fire resilient expansion joint includes one substrate and a second substrate arranged nearly coplanar with the initial substrate as well as an expansion joint that is situated between the first substrate and the second substrate. The expansion joint system comprises an open-cell foam that has a fire retardant substance in it, and the proportion of fire retardant material in the open celled foam is between 3.5:1 to around 4:1 by weight. Then there is an elastomer-based layer placed on the open foam. The elastomer layer and the open-sealed foam create an elongated piece. This section is laid out vertically between the two substrates. The expansion joint also has a terminus section that is located on the other side of the elongated portion and having a flared edge that forms an angle that is elongated and configured to redirect particles and fluid and/or solvent away from the joint system.

Another feature of a fire- and water-resistant expansion joint system is that it has a first substrate; a secondary substrate, which is coplanar with the first substrate and an expansion mechanism that is able to compress between the first and the second substrate. The system of expansion comprises: open celled foam having a fire retardant material infused into it, and where the proportion of the fire retardant material instilled into the foam that is open is within a range of about 3.5:1 to approximately 4:1 by weight; and a layer of an elastomer disposed on the open celled foam. The foam that is open-sealed as well as the elastomer layer make up an elongated portion. The section is located horizontally in relation to the coplanar first substrate (and second substrate) and features an end section that slants around an angle. The portion at the end of the section is vertically-oriented. The expansion joint also includes a termination section located on the vertically oriented section, which is designed to angle around the corner, the termination section comprising an end with a flare that forms an angle with the vertically-oriented end portion and configured to channel particles and fluids and/or solventaway from the expansion joint system.

Another aspect of the invention is that a terminus section consists of: a core and an elastomer layer that is positioned on it; wherein the termination portion is designed for an expansion joint system that consists of an elongated segment configured to be vertically oriented among coplanar substrates. The termination section is located at the one end of the extended section. It comprises an elongated section that forms an angle with the elongated sections . This angle is able to direct solvents, particles or fluids away.

According to a further aspect, a terminus section is comprised of the core; and an elastomer layer that is positioned on the core in which the termination section is designed to be used in an expansion joint system that comprises an elongated section configured to beoriented horizontally between substantially coplanar substrates and having an end portion that is designed to angle in a corner, the end portion is vertically oriented. The termination section is configured to be placed at the end portion to be angled around the corner. It comprises a flared end configured to create an angle to the vertically inclined end portion, and to direct or particles and/or solvents away from the expansion joint system.

According to an additional point, a kit comprises an end section designed to be attached to an elongated part of an expansion joint. The termination section comprises: a core; and an elastomer layer placed on the core. The terminal section is an end with a flare that can form an angle with a portion of the elongated section and is able to direct particles, fluids or solvents away from the expansion joint system.

What is a patent?

A patent is granted by the government to protect an invention, patents give the inventor exclusive rights to use, create to sell, and market the invention? society gains when a new technology is introduced into the marketplace. These benefits could be directly realized as individuals are able to accomplish previously unattainable feats, or indirectly through the opportunities which innovation can bring (business expansion, job creation).

Many pharmaceutical companies and university researchers seek patent protection to protect their research and development. Patents can be granted for the creation of a product, process or method of making new materials. Patent protection has to be granted to an invention that is beneficial unique, innovative, and not already known by others in the same field.

Patents are a way to honor inventors who have commercially successful inventions. They act as a motivator for inventors to invent. Small-scale businesses and inventors are certain that they will receive the most return from the investment they make in technology development through patents. They could earn a decent income by their work.

Patents are a crucial part of companies, and they can:

Create and protect the latest products and services;

Enhance the value, visibility, and attractiveness of your products market;

Make your brand stand out from the rest.

Access to business and technical knowledge and information;

Avoid accidentally using third-party content, or losing important data, creative outputs or any other outputs that are creative.

Patents effectively transform the inventor’s knowledge into a marketable asset that opens up new possibilities for employment creation and expansion of businesses through licensing or joint ventures.

Investors in the commercialization and development of technology will find small companies with patent protection to be more attractive.

Patenting can generate innovative ideas and inventions. The information you create may be eligible for patent protection.

Patents can be used as a deterrent to untrustworthy third parties that profit from the efforts of an invention.

Patent-protected technology that is commercially profitable could be used to fund technological research and development (R&D) which will increase chances of better technology in future.

You can use the intellectual property rights of your company to convince investors and lenders that your product is a viable commercial potential. One powerful patent may provide multiple financing opportunities. Patents as well as other IP assets can be used as collateral or as security for debt financing. Investors are also able to view the patents you own to boost their valuation of your company. Forbes and other publications have reported that each patent can add between $500,000 and million dollars to your company’s valuation.

Start-ups need a well-constructed business plan that leverages the IP to show that your product/service is unique and superior or ingenuous. In addition, investors will be impressed if you can show that your IP rights are secure or is in the process of becoming secure, and that they align with your business strategy.

It is essential to keep an invention secret before submitting a patent application. Public disclosure of an invention can frequently devalue its originality and render it invalid. Therefore, pre-filing disclosures (e.g. for testing-marketing, investors, or other business partners) should only be made upon signing a confidentiality contract.

There are numerous types of patents. Knowing the different types of patents is vital for protecting your invention. Utility patents cover new methods and inventions made by machines. Design patents cover ornamental designs. Utility patents are best to protect the proprietor from copies and competitors. Frequently, utility patents are issued to improve or modify existing inventions. Utility patents can also be used to improve or modify existing inventions. For instance, a procedure patent covers acts or methods of doing one specific thing, whereas a chemical composition will include the combination of components.

How long will a patent last? Although utility patents are valid for 20 years from the date of the initial filing, they can be extended through delays at the Patent Office.

Do you want to protect your idea? Patents are granted only to applicants who are the first to file, therefore you need to file your patent application quickly. Call PatentPC today to file your patent application approved!

Patent searches are an essential step when you’re writing a patent application. This will allow you to look at other concepts and provide insights into them. This will allow you to restrict the extent of your idea. It is also possible to find out about the current technological advancements in the field you’re inventing. This will allow you to know the extent of your invention as well as prepare you for the filing of the patent application.

How to Search for Patents

The first step in getting your patent is to conduct the patent search. You can do a google patent search or do a USPTO search. Once the patent application is filed, the product subject to the application may be called patent-pending, and you will be able to locate the patent application on public pair. Once the patent office approves the application, you can do a patent number search to find the patent that was issued and your product is now patented. In addition to the USPTO search engine, you may also use other search engines like espacenet as described below. A patent lawyer or patent attorney can advise you on the process. In the US patents are granted by the US patent and trademark office, or the United States patent and trademark office, which also reviews trademark applications.

Are you looking for similar patents? These are the steps to follow:

1. Create a list of terms for your invention, based on its purpose, composition, or use.

Write down a concise, but precise description of the invention. Avoid using generic terms such as “device”, “process”, and “system”. Consider synonyms for the terms you initially chose. Also, keep track of important technical terms and key words.

Use the questions below to help you identify keywords or concepts.

  • What is the objective of the invention? Is it a utilitarian device or an ornamental design?
  • Is the invention a way of making something or performing some function? Is it a product?
  • What is the composition of the invention? What is the physical structure of the invention?
  • What is the goal of the invention?
  • What are the technical terms and keywords that define the nature of an invention? A technical dictionary will help you find the appropriate words.

2. Utilize these terms to locate pertinent Cooperative Patent Classifications for your invention at the Classification Text Search Tool. If you’re not able to find the right classification to describe your invention, look through the Schemas of classes (class schedules). Think about substituting the words you’re using to describe your invention if you don’t receive any results from your Classification Text Search with synonyms similar to the words you used in step 1.

3. Go through 3. Check the CPC Classification Definition for confirmation of the CPC classification you have found. The hyperlink to a CPC classification definition will be provided in the event that the title of the classification has a blue box that includes “D” to its left. CPC classification definitions can aid you in determining the classification’s scope so that you can pick the one that is the most relevant. In addition, these definitions can include research tips and other suggestions which could be helpful to further study.

4. The Patents Full-Text Database and the Image Database allow you to retrieve patent documents that include the CPC classification. By focusing on the abstracts and illustrations, you can narrow down your search to the relevant patent documents.

5. Utilize this list of most pertinent patent documents to study each one in depth for any the similarities to your idea. Take note of the specifications and claims. Refer to the applicant and patent examiner to obtain additional patents.

6. Search for patent applications that have been published using the CPC classification you selected in Step 3 in the Applications Full-Text and Image Database. You can also use the same strategy of searching you utilized in step 4 to limit down your search results to just the most relevant patent applications by looking over the abstracts and drawings for each page. After that, you must review every patent application that has been published with care with particular attention paid to the claims as well as other drawings.

7. You can search for additional US patent publications by keyword searching in AppFT or PatFT databases, and also the classification search of patents that are not issued in the United States as in the following table. You can also make use of search engines on the internet to search non-patent literature disclosures about inventions. For instance:

  • Add keywords to your search. Keyword searches may turn up documents that are not well-categorized or have missed classifications during Step 2. For example, US patent examiners often supplement their classification searches with keyword searches. Think about the use of technical engineering terminology rather than everyday words.
  • Search for foreign patents using the CPC classification. Then, re-run the search using international patent office search engines such as Espacenet, the European Patent Office’s worldwide patent publication database of over 130 million patent publications. Other national databases include:
  • Search non-patent literature. Inventions can be made public in many non-patent publications. It is recommended that you search journals, books, websites, technical catalogs, conference proceedings, and other print and electronic publications.

To review your search, you can hire a registered patent attorney to assist. A preliminary search will help one better prepare to talk about their invention and other related inventions with a professional patent attorney. In addition, the attorney will not spend too much time or money on patenting basics.
