Title: System and method for combining multiple composite video signals
Inventor: SIANN JONATHAN I
IPC: H04N5/45
Filed: 1992-04-21
Abstract: A  system and method are provided  for combining multiple composite video signals into a single output data stream synchronised with  an  output  device.  The  system  includes means for decoding incoming composite video  signals into their  constituent  components,  memory  means  for  storing signals temporarily to  synchronise  such signals with the output  device,   and  a  multiplexor  for  combining  the synchronised signals for application to the output device. An  analogue  to  digital  converter  (ADC)  is  arranged  to convert incoming composite video signals into digital form, a digital memory is arranged to receive the digital output of the ADC, and a decoder is provided to sample the contents of  this  memory  under  the  control  of  timing  signals synchronised with the output device to develop synchronised digital  samples relating to the incoming composite video signals. These digital samples are then transferred to the multiplexor to enable the multiplexor to develop the single output data stream. This system requires less memory space than needed by prior art systems and enables high quality colour representations such as 24 bit RGB to be developed without increasing the memory requirement of the system.

Title: Method for infusing raisins with high levels of humectant
Inventor: HARTSON BARTON L
IPC: A23L19/00
Filed: 1992-09-16
Abstract: ABSTRACT      Softness  retention  characteristics  of  raisins  are improved by applying to the surface of the raisins a pure edible polyalcohol humectant, preferably glycerol, at a rate of 20-28% based on the weight of the raisins.  The raisins and humectant are then tempered by immersing the raisins and humectant in additional humectant solution at a temperature of 90°-100°F (32°-44°C) for a times efficient to enable the raisins to absorb the humectant to an amount of about 10-19% by weight.  The raisins are then removed from the humectant  solution and thereafter dried to a moisture content of 7-20%.

Title: Arc discharge ballast suitable for automotive applications
Inventor: GARRISON ROBERT L
IPC: H05B41/38
Filed: 1991-06-20
Abstract: A circuit for starting and operating a high intensity discharge (HID) lamp in a dc mode includes a pulse with modulator (PWM) coupled to first and second direct current input terminals. The PWM  includes a high frequency generator driving a pair of semiconductor switches. A first transformer having primary and secondary windings is coupled to the semiconductor switches. A rectifier and voltage multiplier circuit converts the voltage across the secondary winding of the first transformer to a direct current voltage. A  first energy storage circuit coupled to the rectifier and voltage multiplier circuit stores energy for generating a high voltage spike which initiates a glow condition in the lamp. A second energy storage circuit, which stores energy for application to the HID lamp during starting, insures proper glow-to-arc transition.  The starting and operating circuit further includes a second transformer having first and second secondary windings coupled to the HID lamp and a pulse winding coupled to the first energy storage circuit. Preferably, the windings of the second transformer are adapted to apply a negative-going pulse across the lamp. The application of a negative-going pulse prevents failure of the quartz region of the glass around the lamp cathode by insuring that electrons properly migrate from the cathode to the anode. Moreover, the use of the negative-going pulse improves hot restriking.

Title: Apparatus and method for performing anastomosis fastener securement of hollow organs
Inventor: TZAKIS ANDREAS G
IPC: A61B17/115
Filed: 1993-01-27
Abstract: An anastomosis fastening technique wherein an annular fastener securing anvil is positioned over the end portion of a first hollow body organ to be joined to a second hollow body organ end or side portion and this first organ end is everted outwardly back over the anvil thereby forming a cuff. The anvil is provided with prepositioned and annularly disposed fastener securing devices on the exterior surface. The second hollow body organ and/or side portion is then positioned over the cuff of the first hollow body organ such that the intimal portions thereof to be anastomosed are in intimal coaptation. An anastomotic surgical fastener driving instrument with fastener cartridges therein, and which conforms in shape to the outer annular contours of the anvil is coaxially applied over the anvil with the organ portions positioned therebetween and the fastener driving instrument is then actuated to fasten the coaptating organ portions together. The organ portions to be anastomosed may first be tied down to the anvil. The fastener driving instrument is also keyed to the anvil for proper positioning of the fasteners relative to the anvil fastener securing devices prior to actuating the fastener driving instrument. The fasteners may be in the form of surgical staples, nails or tacks.

Title: Controlling the velocity of projectiles from gas-powered guns
Inventor: BHOGAL MOHAN
IPC: F41B11/32
Filed: 1993-02-10
Abstract: ABSTRACT OF THE DISCLOSURE A gas-powered gun fires a projectile at a settable velocity unaffected by substantial increases in the operating pressure of a gas cartridge. The gun has a compartment for accumulating a charge of gas. The compartment includes a chamber whose inlet is controlled by a valve member normally in a closed state. A biasing spring urges a piston assembly within the chamber to deflect the valve member to an open state, allowing pressurized gas flow from the cartridge to the chamber. The pressure of the accumulating gas charge urges the piston assembly away from the valve member. The gas accumulated in the compartment attains only a predetermined threshold when the valve member returns to its closed state. A trigger-controlled discharge valve releases the accumulated gas charge at the threshold pressure into the barrel to fire the projectile. A manually-operable mechanism allows adjustment of the pressure threshold by compressing or expanding the biasing spring thereby setting the expected velocity of a projectile fired from the gun.
