Title: Method and apparatus for reducing a copy protection process by modifying the blanking level
Inventor: WONFOR PETER J
IPC: H04N5/913
Filed: 1994-05-09
Abstract: Enhancements to a video anticopying process that causes an abnormally low amplitude video signal to be recorded on an illegal copy. The enhancements in one version introduce into the overscan portion of the television picture, just prior to the horizontal or vertical sync signals but in active video, a negative going waveform that appears to the television receiver or video tape recorder to be a sync signal, thereby causing an early horizontal or vertical retrace. One version provides (in the right overscan portion of the picture), a checker pattern of alternating gray and black areas which causes the TV set on which the illegal copy is played to horizontally retrace earlier than normal in selected lines with a consequential horizontal shift of the picture information on those lines. This substantially degrades picture viewability. In another version a gray pattern at the bottom overscan portion of the picture causes vertical picture instability. In another version selected horizontal sync signals are narrowed, causing irregular vertical retraces. Also provided is apparatus for removing or attenuating these enhancements from the video signal, to allow copying.

Title: Air intake flow device for internal combustion engine
Inventor: ROBLEY SPENCER H JR
IPC: F15D1/02
Filed: 2003-09-16
Abstract: An air intake flow device to manipulate the airflow in an air entry chamber of a positive displacement internal combustion engine. The air intake flow device is comprised of a skirt defining an air flow passageway, multiple vanes extending into the airflow passageway from a first leading edge at the surface of the skirt. The configuration of the vanes direct the airflow into a vortex like configuration which is understood to improve air intake across the intake valve into the combustion chamber and thereby improve oxidation of the fuel.

Title: High temperature, high pressure retrievable packer
Inventor: KILGORE MARION D
IPC: E21B33/129
Filed: 1997-03-05
Abstract: In a retrievable packer adapted for service under high temperature and high pressure operating conditions, improved retention of the packer in the wellbore is achieved by use of an inventive slip/wedge system, wherein the cones on the wedges are spaced a progressively slightly greater distance apart from their corresponding slip cones, from the centermost slip cone to the outermost slip cone. This forces the center of the slip to be loaded first. As greater forces are exerted on the wedges from end to end, the wedge will deform slightly and the next cone of the wedge will make contact with its matching portion of slip.  Thereby, as the wedges are loaded higher and higher, more wedge cones come into bearing contact with the slip. Further, a barrel slip is used, to provide a uniform circumferential distribution of forces. This design effectively allows initial setting of the packer with very little slip tooth contact area. This permits the slip to quickly get a good grip into the casing wall. Subsequent higher loading brings more and more slip teeth to bear and prevents overstressing the casing.

Filed: 2000-09-08
Abstract: The invention relates to the food industry. The inventive method for produci ng a granular substance involves the following: mellow grains having an undamag ed membrane and a hyaline layer are husked with the aid of a husker (5) in such a way that part of the outer layer of the kernel seed coat of the grain is removed in a quantity which is equal to or less than 5 % the initial weight of the grain, the integrity of the hyaline layer of the seed coat being preserved. The grain is cleaned with the aid of flowing water in a device (7 ) for cleaning grain from impurities and in a device (6) for washing the grain surface, which are part of a surface cleaning module (1). The cleaned grain is germinated in receptacles (40) of a grain germination module (2) by flooding the grain with a liquid and supplying air thereto with the aid of a perforat ed tube (43) of an air supply system. Germination of the grain is carried out, for example in an isothermal chamber (46) at a liquid temperature ranging fr om 20 ~C to 40 ~C, said temperature being uniform throughout the total volume o f the grain. Said germination is carried out until a humidity equal to or not less than 38 % and a pH of the liquid in the 3.4-6.0 are reached. The granul ar substance is produced with the aid of grain breaking machines (51) formingpa rt of a grain breaking module (3) by breaking the germinated grain using blade pressure knives until particles of not more than 0.4 mm are produced a t a temperature not exceeding protein denaturation temperature of the produced granular material.

Title: Temperature controlled in situ wax purification
Inventor: SAY GEOFFREY RHYS
IPC: C07C9/22
Filed: 2002-06-14
Abstract: A hydrocarbon wax product from a HCS slurry comprising liquid synthesis product and catalyst particles is purified by circulating the slurry from a synthesis zone with a first temperature through a treatment zone with a second temperature in which a hydrogen-containing treatment gas contacts the slurry.  The gas treatment removes impurities from the hydrocarbon wax product and also removes catalyst de-activating species which may be present in the slurry.  Purified wax product is separated and removed from the treated slurry via wax withdrawal means. This avoids or minimizes the need for further treating the wax product. Remaining treated slurry may be returned to the synthesis zone.
