Software Technology for Cooling methods for diaphragm pumps with an electrically powered motor

INGERSOLL-RAND INDUSTRIAL U.S., INC. (Davidson, NC)

A diaphragm pump has a motor that drives an armour in a rotating motion. The first diaphragm connects to an armature at the first end. It is positioned in the first pumping room and is designed to move fluid in and out in response to the reciprocating linear motion. A cooling intake valve and a cooling exhaust valve are in operative communication with the first diaphragm, in which case, as the armature moves to stretch the first diaphragm, which reduces the volume of the first pumping chamber, the initial diaphragm pulls air from the surrounding area behind the diaphragm first through the cooling intake valve, and when the armature reverses to cause the first diaphragm to increase the volume of the first chamber for pumping, the initial diaphragm pushes ambient air out of the first chamber through the cooling exhaust valve.

Technical Field

The present disclosure is related to diaphragm pumps and other pumps that are positive displacement that make use of the rotating action of a flexible diaphragm.

The state of the art

A diaphragm pumps is typically described as an inverse displacement pump that uses the reciprocating action of a diaphragm with a flexible structure and the valves that correspond in fluidic connection with the diaphragm for the purpose of pumping an fluid.

In order to create a pump chamber the diaphragm must be sealed. The diaphragm’s flex could cause the volume of the chamber to increase and decrease. The volume of the chamber grows as the volume decreases. As the volume decreases then the liquid to be pumped is able to enter into the chamber. The liquid is removed from the chamber. This process is repeatable and creates the pump’s reciprocating action. the pump.

However, the repetition of the action could create low efficiency. Therefore, it is necessary to improve the efficiency of diaphragms and other positive displacement pumps.

What is a patent?

Granted by the government to safeguard an invention patents give the inventor with exclusive rights to use, create, market and promote the invention?society gains when a new technology is introduced to the market. Benefits can be realized in direct terms, as it can allow people to accomplish previously unattainable things. Or indirectly by the economic benefits (business growth and employment) which the invention provides.

Patent protection is demanded by many university researchers and drug companies to protect their research and development. Patents may cover the physical or abstract nature of a product or process , or the method or composition of materials that are new to the field. Patent protection must be granted to an invention that is useful, novel, and not yet known by other people in the same area.

Patents are awarded to inventors who have commercially successful inventions. They are an incentive to inventors to come up with new ideas. Patents enable entrepreneurs and inventors to be confident that there’s the possibility that they’ll be paid back for their efforts, time and money spent on the development of technology. They can earn money through their work.

Companies that are able to:

Secure innovative products and services;

Improve the visibility and the value of your products ‘ presence on the market

Make your brand stand out from others.

Get technical and business information.

Be careful not to accidentally use third-party content or you risk losing important information as well as creative outputs and other outputs.

Patents can transform an inventor’s knowledge into a marketable asset which opens new opportunities to create jobs and boost business expansion by licensing or joint ventures.

Investors in the development and commercialization of technology may find small companies with patent protection more appealing.

Patenting may lead to new ideas and new inventions. This information could be patent-worthy.

Patents can be used to prevent untrustworthy third parties from making money from the invention’s efforts.

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

Intellectual property ownership is a way to convince investors and lenders that there are real chances to market your product. A powerful patent can open the door for numerous financing options. Patents as well as other IP assets are able to be used as collateral or as security to finance debt. Investors can also see your patent assets to boost company valuation. Forbes and others have noted that each patent can increase the value of a company by anything from $500,000 to $1 Million.

A solid business plan is crucial for new businesses. It must be based on IP and demonstrate what your service or product is distinct. Investors will also be impressed if you demonstrate that your IP rights are secure or are in the process of becoming secure, and that they are in line with your business plan.

It is important to keep your invention secret until you apply for patent protection. A public disclosure of an invention can frequently devalue its originality and make it invalid. Therefore, prior filing disclosures (e.g., for test-marketing investors, test-marketing, or any other business partners) should only be filed upon signing a confidentiality contract.

There are many kinds of patents. Understanding them is crucial to protect your invention. Utility patents are for inventions and processes that are new. Design patents cover ornamental designs. Patents for utility are the best option and shield the owner from copycats and competitors. They are typically granted to enhance or modify existing inventions. Utility patents also cover improvements and changes in existing inventions. For example, a process patent covers acts or methods for performing one specific thing, whereas a chemical composition will include the combination of ingredients.

What is the average length of patents? While utility patents are valid up to 20 years from their initial filing, they may be extended by delays in the Patent Office.

Patent searches are an essential step when you are drafting the patent application. This will enable you to discover different ideas and provide an understanding of the potential of them. This can help you limit the extent of your idea. In addition, you can be aware of the current state of technological advancements in your field of innovation. This will assist you in comprehend the scope of your invention as well as prepare you to file your patent application.

How to Search for Patents

Patent searches are the first step towards obtaining your patent. You can do a google patent search or do a USPTO search. Once the patent application is filed, the item covered by the application can be referred to as patent-pending and you will be able to locate the patent application online on the public pair. After the patent office approves your application, you’ll be able to conduct an examination of the patent number to find the patent issued. Your product is now patentable. You can also use the USPTO search engine. See below for details. For assistance, consult a patent lawyer. In the US, patents are issued by the US patent and trademark office, also known as the United States patent and trademark office, which also reviews trademark applications.

Interested in finding more similar patents? Here are the steps to follow:

1. Create a list of terms for your invention in relation to its intended composition, use, or purpose.

Write down a short, but precise explanation of your invention. Avoid using generic terms like “device”, “process” and “system”. Instead, look for synonyms for the terms you chose initially. Also, keep track of significant technical terms as well as key words.

To help you find terms and keywords, you can use the following questions.

• What is the objective of the invention? Is it a utilitarian device or an ornamental design?
• Is invention a way to create something or perform some function? Or is it a product or process?
• What is the composition of the invention? What is the physical composition of the invention?
• What is the goal of this invention?
• What are technical terms and keywords that describe the characteristics of an invention? A technical dictionary can help you identify the correct terms.

2. Use these terms to search for pertinent Cooperative Patent Classifications for your invention at the Classification Text Search Tool. If you’re not able to locate the appropriate classification for your invention, scan through the classification’s Schemas of classes (class schedules). If you don’t get any results from the Classification Text Search, you might consider substituting your words to describe your invention with synonyms.

3. Examine 3. Go over the CPC Classification Definition to verify the validity of the CPC classification you’ve discovered. The hyperlink to the CPC classification definition will be available when the classification you have selected is a blue square with a “D” on the left. CPC classification definitions will help determine the scope of the classification and therefore you’re sure to select the most relevant. Additionally they can provide search tips and other suggestions that may be useful to further study.

4. Retrieve patent documents with the CPC classification from the Patents Full-Text and Image Database. By focusing on abstracts and representative drawings you can narrow your search to find the most relevant patent publications.

5. Use this selection of the most pertinent patent documents to study each one thoroughly for the similarities to your invention. Be sure to read the specification and claims. It is possible to find additional patents through contacting the patent examiner as well as the applicant.

6. It is possible to find published patent applications that match the CPC classification you selected in Step 3. You can apply the same search strategy as Step 4, narrowing your search results to the most relevant patent applications by examining the abstract and representative illustrations on every page. Next, examine all published patent applications carefully, paying special attention to the claims as well as other drawings.

7. You can look up other US patent publications by keyword searching in AppFT or PatFT databases, and also the classification search of patents that are not from the United States according to below. You can also use web search engines to search non-patent patent disclosures in literature about inventions. Here are a few examples:

• 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:
• European Patent Office (EPO) provides esp@cenet to access a network of Europe’s patent databases with access to machine translation of European patents. 
• Japan Patent Office (JPO) – with access to machine translations of Japanese patents.
• World Intellectual Property Organization (WIPO) offers PATENTSCOPE with a full-text search of published international patent applications and machine translations for some documents, as well as a list of international patent databases.
• Korean Intellectual Property Rights Information Service (KIPRIS)
• State Intellectual Property Office (SIPO) with machine translation of Chinese patents.
• Other International Intellectual Property Offices with online patent databases include Australia, Canada, Denmark, Finland, France, Germany, Great Britain, India, Israel, Netherlands, Norway, Sweden, Switzerland, and Taiwan.
• 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.
