Delphion Patent Searches * Delphion Simple Patent Searches.

This website is one of the most fasinating locations on the web. This site has a history of real inventions.

Be patient. The server is used heavily. The data is on archived CDs. The mechanical CD retrieval robot is slow at getting the next patent. Once the CD is in the drive the next pages should come through faster.

Things have turned a bit ugly. Before you could see the full patent pages. Now you can only see the first page. To see the whole thing requires an expensive subscription.

* You Don't Really Want A Patent, Do You?
* Don Lancaster's Patent Avoidance Library.
Don discusses many of the pitfalls of obtaining and keeping patents. He makes a convincing argument that there is no need for obtaining a patent unless the gross sales are greater than $12,000,000.

(Miller, now deceased, built several cars in Joplin, Missouri. These were based on a Ford Escorts chases. The engine was composed of 2 halves. Each half has two double acting cylinders in series for a total of 4 expansions. Each half was geared up, yes geared up 18 to 1, and directly connected to each front wheel. The storage tank was a light weight fiberglass pressurized to 3500psi. The high pressure was reduced through an expansion pressure regulator to 500psi. The engine power was controlled by a throttling valve to 0 to 500psi.)

( <Robert L. McWilliams III >in an email to me wrote:
I did some serious and time consuming digging around, but I think I have at least narrowed down the time frame. The earliest reference I have to a patent for dichlorodifluoromethane (CFC-12, R-12, Freon 12) is 1934. It was originally patented by a joint venture company formed by E.I. DuPont de Nemours and General Motors. Freon was originally trademarked in 1931 by E.I. DuPont de Nemours and covered all of their halocarbon products. Allied Chemical Corporation began producing its own dichlorodifluoromethane in September 12, 1951 under the trade name of Genetron. 1951 - 1934 = 17, the number of years granted an original patent so 1934 looks like the year that R-12 was patented. The original patent number is 1,953,216.

Vertical-axis wind turbine with two-phase sails
(Flapping Sail with interesting method to control the opening and closing of the sail by mechanical communication through connecting lines. The sails are triangular. As I see it, the basic improvement is in the mechanical communication through connecting lines. Similar patents without the communication lines are: DeBerg and Weisbrich. I believe these two patents are direct prior art because they, along with Green, maintain the shape of the sail by use of a single strait spar and flexible lines. Less similar prior art are: Chen and Goldwater. These patents maintain the shape of the sail using lines and meshes. Barnard obtains the sail shape with a single curved spar and without the use of either lines nor meshes. Other patents, Hillman and Rhodes, communicate the position of the working sail to the idle sail by use of a rotating shaft. This mechanism is similar to Green's use of communicating lines. All the flapping sail patents have similarities to Green's flapping sail patent.
