Inventor: CERAMI ANTHONY
IPC: C07H19/01
Filed: 1996-11-15
Abstract: The present invention relates to compositions and methods for inhibiting the aging of amino-containing amino acid, peptides, proteins and biomolecules.  Accordingly, a composition is disclosed which comprises an agent or compound capable of reacting with the glycosyl-amino moiety of the early glycosylation product (also known as the Amadori product or the Heyns product) formed by the reaction of glucose, or other reactive sugars, with an amino-containing peptide, protein or biomolecule, thus stabilizing this early glycosylation product, and preventing its further reaction to form open-chain, carbonyl-containing advanced glycosylation end products. Suitable agents may contain a reactive aldehyde group. A preferred agent is acetaldehyde. The method comprises contacting the target biomolecule with the composition. The compounds so obtained are represented by formulae (VI) and (VIII) wherein R is the residue of an amino-containing biomolecule such as a peptide and CH2R' is the residue of the reactive aldhehyde group. Both industrial and therapeutic applications for the invention are envisioned, as food spoilage and animal protein aging can be treated.

Abstract: A payload design (100) for a multi-spot-beam satellite communication system includes a plurality of uplink spot beam receivers (102) and downlink spot beam transmitters   (104),  and  a  broadcast  transmitting subsystem (122, 124 and 130) capable of transmitting a broadcast beam (22)  to an entire system geographical service area.  An input filter-switch-matrix (IFSM 132) controllably selects input IF signal bands for routing to an on-board digital signal processor-router  (DSPR 120).  The DSPR (120) subsequently routes all received point-to-point  and  broadcast  data  packets  to  the appropriate  downlink  spot or  broadcast  transmitting subsystems  for transmission thereof.   The broadcast downlink allows broadcast transmissions to occur at the highest efficiency possible,  while also allowing for flexible provision of surge capacity for point-to-point transmissions on previously exhausted spot beams by selective use of the broadcast beam for such point-to-point transmissions.

Title: High luminance electrodeless projection lamp
Inventor: LAPATOVICH WALTER P
IPC: H01J65/04
Filed: 1998-06-22
Abstract: An Electrodeless High Intensity Discharge (EHID) lamp for projection applications. The lamp has a small (nominal dimensions: 2mm I.D., 3mm O.D., 6mm internal length) capsule, which is constricted in a mid-portion thereof. The constriction squeezes the plasma within the capsule and provides a higher power density. This in turn produces a higher luminance in the center of the arc.  This focal point of the projection system is constant over the life of the lamp, owing to the fact that the system is electrodeless. The arc tube or capsule is thickened in the vicinity of the constriction to permit heat transfer through the vitreous silica (commonly called quartz). The thickening carries the heat away from the now hotter mid-portion area. This thickening cools by virtue of increasing the thermal conduction through the glass.

Title: A method and manufacture of an axial tensioned bolt
Inventor: GOSLING MARTIN C
IPC: F16B31/00
Filed: 1997-01-10
Abstract: A method of tensioning a bolt having parallel threads coupled to a nut having a coil insert, employed to join mating flanges of an equipment housing. A hydraulic tensioner tensions the bolt. In one embodiment, the tensioner rests on a bridge, which in turn rests on the surface of the housing around the nut. The tensioner is attached to the threads of the bolt. The bolt is stretched by the tensioner pulling on the bolt while pushing against the bridge. In another embodiment, a stool with a wide top face rests on the surface of the housing and the bolt extends through the stool and engages the nut. The bridge rests on the top of the stool while the tensioner stretches the bolt. In a third embodiment, a parallel action hydraulic tensioner is attached to and pulls both ends of the bolt to stretch it.

IPC: B65G23/08
Filed: 1998-07-28
Abstract: The present invention relates to a drive roller for endless-belt or chain-belt conveyors. It is powered by a hydraulic motor that is wholly enclosed within the roller. One shaft of the roller is stationary and is ported to permit passage of hydraulic fluid to and from the motor. The stationary shaft terminates in a flange that is bolted to the hydraulic motor end plate to provide simple yet robust support for the motor. The fluid ports are within this flange and are O-ring sealed. The second roller shaft rotates with the outer drum. This novel and simple design requires only one internal bearing thus greatly reducing the complexity and cost compared to prior art drive rollers. The hydraulic roller is readily mounted on existing conveyor structures.

Title: Method and apparatus for decoding spatiochromatically multiplexed color images using predetermined coefficients
Inventor: MARTINEZ-URIEGAS EUGENIO
IPC: H04N7/26
Filed: 1997-07-03
Abstract: Color image decoding is achieved by a simplified method of decoding a spatially and chromatically multiplexing image plane (32), such as a plane consisting of RGB (Red-Green-Blue) pixels (22) by performing a summation of pixels of all three colors in a neighborhood of a missing pixel. The decoding process has applications in decoding images made by a data processor, made by an imaging device with a mosaic color filter, or made by a multi-sensor CCD imaging device with a sensor offset (800). Various techniques of entropy reduction, smoothing and speckle reduction may be incorporated into the coefficient pattern. The coefficient pattern may be generated automatically using a process of correlated decoding or may be developed by hand using a process of trial and error.
