Title: Method and apparatus for providing two parties transparent access to a single-port memory storage device
Inventor: MCKENNA JAMES L
IPC: H04L29/06
Filed: 1992-10-01
Granted: 2000-12-12
Abstract: A data communication controller having a memory access control unit characterized by a symmetrical access port architecture. The memory access control unit allows both a host processor and the medium access control (MAC) unit of the data communication controller to transparently access a single-port data packet buffer memory while operating a full specified operating speed and without interference between simultaneous memory access requests. The memory access control unit arbitrates asynchronous memory access requests from both the host processor and the medium access control unit, while permitting each of these processors unlimited access to the single-port buffer memory as if it alone had the full memory available to itself at all times. The above capabilities are achieved using automatic address incrementation and data-byte prefetching operations, without requiring the use of a port processor or additional internal data buses.

Abstract: An improved scissors jack which has a lead screw that does not extend beyond the confines of the jack when the jack is in the partially raised position so as to reduce the space required for storing the jack. A holiow member is formed with a slot in which the extension of the threaded screw is received so that the end of the screw can slide in the slot when the jack is in the unloaded position to allow the jack to be raised to a mid height condition for storage. Under use, the extending portion of the screw moves to the end of the slot in the hollow member so as to apply tension to the lead screw to thus raise and lower the jack as the lead screw is rotated.       A modified form of the invention utilizes an extended hollow trunion which prevents the end of the lead screw from extending beyond the confines of the trunion and a further modification provides for pivotally connecting two portions of the lead screw so that the jack can be moved to a stored condition.

Title: Process for preparing soft centers in food products
Inventor: WHEELER EDWARD L
IPC: A23L25/00
Filed: 1993-07-28
Granted: 2005-01-04
Abstract: Food products having soft or liquid centers, layers or other areas are formulated by arranging two fat-containing compo-nents contiguous with one another. A fat in the first component migrates into the second, forming a mixture having a lower solids content than the second fat while the structural integrity of the first component is maintained. The process is especially adapted to the formation of soft- and liquid-centered confections. One preferred embodiment employs fats bearing long, saturated C16 to C22 fatty acid residues and a mixture of short C2 to C4 acid residues, preferably containing acetic acid residues, as the mi-grating fat in a confectionery coating, and hydrogenated coconut or palm kernel oil as the fat in the confectionery center. An especially preferred embodiment employs, as the migrating fat, triglycerides bearing long, saturated substituents con-taining at least about 75 % stearic acid residues and short residues derived from acetic acid, a mixture of acetic and propion-ic acid, or a mixture of acetic and butyric acid. Since sucrose and invertase are not essential elements of the center, artificial sweeteners can be used to replace all or part of the sucrose, resulting in reduced calorie confections. Caloric reduction is fur-ther enhanced because preferred migrating fats are low in calories.

Title: Vapor-air steam engine
Inventor: GINTER J LYELL
IPC: F02C3/30
Filed: 1993-10-27
Granted: 2008-01-08
Abstract: A vapor-air steam engine is described which operates at high pressure and utilizes a working fluid consisting of a mixture of compressed uncombusted air components, fuel combustion products and steam.  In the new cycle described, working fluid is provided at constant pressure and temperatures. Combustion air is supplied adiabatically by one or more stages of compression.  Fuel is injected at pressure as needed. At least about 40 % to all of compressed air is burned. Inert liquid is injected at high pressure to produce steam and thus provide an inert high specific heat diluent vapor required for internal cooling of an internal combustion turbine or other type system. The use of extensive liquid injection inhibits the formation of pollutants, increases the efficiency and horsepower of an engine; and reduces specific fuel consumption.  The new cycle may also be operated open or closed;  in the latter case, the liquid may be recouped via condensation for regenerative reuse. When salt water is injected into the system potable water is recovered from the steam exiting the power turbine and sterile sea salt is recovered from the cumbustion chamber.

Inventor: BACKUS JOHN WESLEY
IPC: C12Q1/6806
Filed: 1995-09-14
Granted: 2009-07-14
Abstract: Nucleic acids can be made available for amplification or other treatment after lysis by contacting the lysate with specific weakly basic polymers to form a precipitate with the nucleic acids at acidic pH. After removing non-precipitated materials, the pH is then made basic, thereby releasing the nucleic acids from the polymer. This method for preparing specimen samples is simple and quite rapid, and the released nucleic acids can be further treated in hybridization assays or amplification procedures. The weakly basic polymers are water-soluble and cationic at acidic pH, but neutral in charge at basic pH.

Abstract: An inflation tool for an external casing packer (ECP) is provided. It allows isolation of each ECP and inflation with mud, cement, or other fluids. The opening for the ECP is isolated by appropriate seals, while a passage in the inflation tool is closed off by a plug which allows internal fluid pressure build-up. A  sliding sleeve valve is responsive to built-up pressure and opens to allow access to the ECP. Upon complete inflation of the ECP, the pressure applied is removed, allowing the sleeve to close and the pressure between the seals surrounding the opening to the ECP is equalized with the wellbore. Excess mud or other inflation material can be reversed out by a bypass feature around the plug. A pressure-relief feature in the inflation tool allows further pressure equalization for the string, which was used to run the tool in the hole, to facilitate its removal.
