Engineering patents

While the principal value of the book is for the professional chemist or student of chemistry, it should also be of value to many people not especially educated as chemists. Workers in the natural sciences—physicists, mineralogists, biologists, pharmacists, engineers, patent attorneys, and librarians—are often called upon to solve problems dealing with the properties of chemical products or materials of construction. Eor such needs this compilation supplies helpful information and will serve not only as an economical substitute for the costly accumulation of a large library of monographs on specialized subjects, but also as a means of conserving the time required to search for... 

Double-acting steam engine patented by James Watt. 

In this chapter we examine the processes that have been developed to produce micro-organisms as a source of food protein. We will examine the reasons why micro-organisms have been considered as alternative protein sources, the substrates on which they have been grown, the various process technologies developed and the comparative economics of these processes. One process will be examined in depth, to illustrate how a team composed of such diverse people as microbiologists, process engineers, patent lawyers and cost analysts work together to develop a marketable product. 

This cycle also uses continuous counterflow heat exchanger and is closely related to the Joule-Thomson and Claude cycles as shown in Fig. 5.15(a) [60], The cryocooling or reverse Brayton cycle derives from a reciprocating gas engine patented by G. B. Brayton in...

In 1849 Eugene Bourdon, a French watchmaker and engineer, patented an instrument used to measure pressure. This instrument is called the Bourdon tube gauge and is one of the most common instruments used in industrial plants. The purpose of this section is to discuss the design, failure, and calibration of these gauges.

Companies involved in the research and development of plant and animals derived from genetic engineering patent these new products and processes. The patent allows them to protect their investment however, it costs farmers who use the seed. A contract between the farmers and these companies prohibits the farmers from saving seed for use the following year, reselling seed to a third party, or exchanging seed with other farmers. 

Hans Pabst von Chain s first demonstrator jet engine used hydrogen as fuel, and the first Heinkel jet engine patent application was for a hydrogen combustion system. 

SciFinder includes information on both chemical patents and patent family members from 44 countries. Since 1907, Chemical Abstracts (CA) has abstracted and indexed over three million patents worldwide in all areas of chemistry and chemical engineering. Patent titles may be altered by the Chemical Abstracts Service to make them more descriptive. SciFinder is an excellent resource for article, paper, and patent searching, since both patent numbers and inventor/assignee names are searchable from 1907 to date bibliographic and abstract information for patents from major industrial countries is available within two days of publication, full indexing is completed within twenty-seven days, and patent family information is available from 1957 to date. 

Morey, S. (1826) Gas or Vapor Engine. Patent USX4378 Lyle, C. and Cummins, J. (1989) Internal Fire, Society of Automotive Engineers, Inc. 

Approximately 80% of the healthcare and engineering patents issued in the USA in 1995 were to US pharmaceutical and biotechnology companies (PhRMA, 1996). CBER regulates over 85% of the 284 biotechnology medicines currently known to be in development (PhRMA, 1996). This indicates not only the large number of products in development but also CBER s experience base in review.
