Title: Hood system for conveyorized cooking oven
Inventor: WELSH CLARKE T
IPC: A47J37/04
Filed: 1988-01-11
Granted: 1992-06-02
Abstract: Abstract of the Disclosure A kitchen exhaust hood covers the top of an oven and food conveyors which extend on both sides of the oven. Plates in the hood cooperate with the walls of the hood to provide slots at the hood front and sides to accelerate the air under the plates adjacent the slots and provide high velocity exhaust air flow upward in the hood at the front and sides of the hood to capture heat and fumes. The plates are located slightly above the lower edge of the hood, to minimize induction of room air horizontally into the hood under the edge, and assure collection of air that has been associated with the oven and has accumulated heat or collected contaminants.  Air flow guides at ends of a conveyor direct heat and fumes around the ends of the conveyor toward the conveyor covering hood portions.

Abstract: ABSTRACT    A video imaging system is disclosed.  The system is responsive to electrical signals introduced into it, which electrical signals represent an image.  The system includes an acoustic-optical cell, the cell including an anisotropic medium for sound transmittal.  The electrical signals are received, and optionally compressed, before being introduced into transducers mounted on the cell.  The transducers convert the electrical signals into sound waves which traverse the width of the cell.  After substantially a full line of display of the image is traveling through the cell, a monchromatic light source, such as a metal vapor pulsed laser, is pulsed for a time duration less than the propagation time of a single pixel across or transverse to the sound signal in the cell.   This modulates the monochromatic light which is then focused and displayed on the screen at the appropriate position for the line of image.

Title: Increased bandwidth for multi-processor access of a common resource
Inventor: CONFORTI JOSEPH A
IPC: G06F13/18
Filed: 1988-02-01
Granted: 1992-02-11
Abstract: INCREASED BANDWIDTH FOR MULTI-PROCESSOR ACCESS              OF A COMMON RESOURCE ABSTRACT OF THE INVENTION This circuitry permits equal access to a shared resource by a number of central processing units (CPUs).  In a multiple CPU arrangement, common resource contention problems arise, when several CPUs attempt to access the common resource. To resolve these contention problems, this circuitry is an improvement to arbitration ring circuitry.  The circuitry of this invention permits each of the CPUs equal access to the common resource during situations in which each CPU is constantly generating requests (high bandwidth utilization) for access to the common resource.  This invention is particularly useful for systems in which a large number of CPUs must have their local memory rapidly reloaded from a common memory source.  Reloading procedures for large numbers of CPUs require up to an hour.  By employing the present invention, these reloading times can be cut from one hour to approximately 5 minutes.
