The invention pertains to a continuous process to convert inorganic solid particles that either are amorphous or possess an orderly degree into inorganic solid products that (a) when the starting particles are amorphous and possess an order level, or (b) when the beginning particles possess a level of order or distinct order, a different degree of order or no order, which particle types are suitable to use as catalysts, or as a carrier, or in or as an adsorbent, during which the initial particles are dispersed in liquids, thus creating an adsorbent. The suspension flows through at most two separate conversion vessels (3) each connected to each other in a series. Each of these vessels (3) are used to stir the suspension. Further, the invention relates to an apparatus that could be used to perform the procedure according to the invention. This invention permits the treatment of suspensions with an extremely high Solids to Liquid Ratio.

It is an object of the present invention to enable the conversion of suspended solid particles, such as (raw) ore and/or mineral particles into suspended inorganic solid product particles that can be used in or as a catalyst,in or as a carrier or in or as an adsorbent.

In one form, the present invention is an ongoing process for the conversion of solid inorganic starting particles that either are amorphous , or have an order level into inorganic solid product particles that (a) in the event that the beginning particles are amorphous, have a degree of order, or (b) when the beginning particles possess a degree of order, an entirely different order, higher degree of order or no order,

Which product particles can be used in or as carriers, catalysts, or adsorbents? The suspension forms when the start particles are mixed with the liquid. The suspension moves through at least twoseparate vessels for conversion that are joined in series, with the suspension being agitated by each of these vessels.

Furthermore, the invention is related to an apparatus for converting inorganic solid starting particles. It comprises a first vessel to disperse the starting particles into liquid, forming an emulsion.

What is a patent?

Patents are granted by the government to safeguard the invention. It gives the inventor the sole rights to create, use and sell the invention. Society gains when new technologies are brought to the market. These benefits may be realized immediately by people who are able to achieve previously impossible feats and indirectly by the economic benefits which innovation can bring (business expansion, job creation).

Patent protection is demanded by many pharmaceutical companies and university researchers for research and development. A patent can cover a physical or abstract product or process, or even an approach or composition of material that are new to the field. Patent protection is granted to an invention that is useful unique, innovative, and not previously known to others in the same area.

Patents are awarded to inventors who have commercially successful inventions. They act as a motivator for inventors to come up with new ideas. Small businesses and inventors can rest certain that they will receive a return on their investment in technology development via patents. This means they will be able to make a living by their work.

Companies with the capacity to:

Secure the latest products and services;

Increase the value, appearance, and visibility of your products market

Make your brand stand out from the competition.

Access business and technical expertise and other information;

Beware of the possibility of accidentally using third-party proprietary content or losing valuable data, original outputs, or another creative output.

Patents can transform an inventor’s knowledge into a commercially tradeable asset which opens new opportunities to create jobs and boost expansion of businesses through licensing or joint ventures.

Small-scale businesses with patent protection will be more attractive to investors in the development and commercialization of technology.

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

Patents can be used as an effective deterrent for untrustworthy third parties profiting from the invention’s success.

Revenues from patent-protected technology that are commercially successful could be used to finance technological research and development (R&D) that will improve the chances of developing better technology in the future.

You can use the intellectual property rights of your company to convince lenders and investors that your product has commercial value. One patent that is powerful could provide multiple financing opportunities. Patents can be used along with other IP assets as collateral or security to secure financing. You may also present investors with your patent assets to increase company valuation. Forbes and others have noted that each patent could increase the value of a company by anything from $500,000 to $1 million.

Start-ups need a solid business plan that is built on the IP to prove that your product/service is distinct, superior, or innovative. In addition, investors will be impressed if you demonstrate that your IP rights are secure or are in progress of being secure and that they support your business strategy.

It is crucial to keep an invention secret before applying for patent protection. A public disclosure of an invention can be detrimental to its novelty and invalidate it. Thus, disclosures that are filed prior to filing (e.g. for testing-marketing investors, investors, or for other business partners) should only be made following the signing of a confidentiality agreement.

There are many kinds of patents. Knowing them is essential for protecting your invention. Patents for utility cover techniques and machines. Design patents cover ornamental designs. Patents for utility are the best option and shield the owner from copycats and other competitors. Utility patents are often granted to enhance or modify existing inventions. Patents issued under utility can be used to improve or alter existing inventions. A process patent would be a way to describe the actions or methods of performing a particular act. However, a chemical composition will include a combination of ingredients.

What’s the duration of a patent last? Utility patents are valid for 20 years after the earliest filing dates, but their expirations can be extended due to delays at the patent office, for example.

Do you want to patent your ideas? As patents are only granted to applicants who file first, you need to file quickly – call a patent attorney at PatentPC to file your invention today!

When drafting an application for patents it is recommended to conduct a patent search, as the search can provide some insight into other people’s concepts. You’ll be able to narrow down the scope of your idea. In addition, you can learn about state of the technological advancements in your area of invention. This will allow you to know the extent of your invention and prepare you for filing the patent application.

How to Search for Patents

  • 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.
