Title: Method for utilizing gas reserves with low methane concentrations for fueling gas turbines
Inventor: MITTRICKER FRANK F
IPC: F02C3/20
Filed: 2000-12-13
Granted: 2005-02-24
Abstract: The invention is directed to a method of fueling gas turbines from natural gas reserves with relatively low methane concentrations. The invention permits the use of such reserves to be used to fuel gas turbines to generate electric power. The method of the invention includes providing a natural gas comprising not more than about 40 percent methane on a volume basis and mixing the methane of the natural gas with hydrogen gas to provide a hydrogen enhanced methane/hydrogen gas blend which has sufficient hydrogen to provide flame stability during burning. Thereafter, if required, the hydrogen enhanced methane/hydrogen gas blend is dehydrated to remove a sufficient amount of water to provide a flame stable hydrogen enhanced dehydrated methane/hydrogen gas blend. The hydrogen enhanced natural gas blend is used to fuel gas turbine generators.

Title: Axial sealing mechanism for a scroll type compressor
Inventor: KIKUCHI KAZUTO
IPC: F04C27/00
Filed: 1990-06-04
Granted: 1995-01-17
Abstract: This invention discloses an axial sealing mechanism for axially sealing an orbiting scroll and a fixed scroll of a scroll type compressor. The com-pressor includes a driving mechanism for driving the orbiting scroll in an orbital motion and a block member fixedly attached to the housing of the scroll compressor to support the driving mechanism. The block member and the fixed scroll define an intermediate chamber in which the orbiting scroll is disposed. The intermediate chamber is divided into a first and second chamber by an end plate of the orbiting scroll. At least one first conduit sized to produce a pressure throttling effect, links the second chamber and the discharge chamber of the compressor to increase the pressure in the intermediate chamber. At least one second conduit, which also is sized to produce a pressure throttling effect, links the second chamber to the suction chamber of the compressor. During operation of the compressor, the second chamber is maintained at an intermediate pressure without pressure fluctua-tion due to the presence of the at least one first and second conduits. This intermediate pressure provides a constant urging force against the orbiting scroll to urge it against the fixed scroll to obtain a good axial seal between both scrolls without decreasing the durability of the driving mechanism and the rotation preventing mechanism or the life of the compressor.

Title: Automatic brightness compensation for x-ray imaging systems
Inventor: MECCARIELLO THOMAS VINCENT
IPC: A61B6/00
Filed: 1991-01-17
Granted: 1999-10-12
Abstract: The brightness of an X-ray video image during fluorography is maintained at a substantially constant level by a control circuit which varies the X-ray dose in relation to changes in the average brightness of the X-ray image. As the X-ray system approaches the limits of its imaging capability, varying the X-ray dose alone may not yield the desired brightness level. At this point, the gain applied to the video signal is increased to improve the brightness. A linear brightness taper function is used such that, as the level of video gain required to maintain constant brightness increases, the actual video gain increases by a smaller proportional amount. This function results in the brightness of the video image decreasing somewhat as the video gain is required to provide a greater degree of brightness compensation. This reduction in brightness not only provides a visual indication to the image observer that the system is approaching the imaging limits, but also creates an illusion that noise artifacts in the image are not intensifying as the video gain increases.

Title: Aircraft aircrew life support apparatus
Inventor: FOOTE JAMES CONWAY
IPC: A62B9/02
Filed: 1991-03-12
Granted: 2001-02-27
Abstract: A breathing demand regulator for use in aircrew life support apparatus has an aneroid capsule 56 coacting with a valve head 50 to restrict outflow from a breathing pressure control chamber 32. The aneroid capsule expands t.o move the valve head in the event of aircraft cabin altitude rising above a predetermined level due to loss of cabin pressure. An end face 53 of a valve stem 51 supporting the valve head senses inflation pressure of an aircrew G-suit by way of a passageway 59 for movement of the valve head in the presence of G-load. This arrangement provides for increased control pressure and, hence, increased breathing gas pressure in a regulator outlet 13, in meeting the higher of requirements for positive pressure breathing to protect an aircrew member exposed to both G-load and high aircraft ambient altitude (say above 12000 metres).      The regulator is disclosed in combination with an anti-G valve arrangement 90, 100 and a G-suit inflation control valve arrangement 60, 61 and 120, 121 that provides the higher of G-suit inflation pressure requirement for protecting the aircrew member when exposed to high aircraft ambient altitude in the presence of G-load.
