Title: Reactor control system verification
Inventor: GALLIGAN JAMES J
IPC: G21D3/04
Filed: 1988-03-03
Granted: 1993-07-06
Abstract: Abstract of the Disclosure A computer controlled system and method accurately and rapidly verifies the in-place, dynamic response of a transducer/sensor to a time dependent state variable.  The verification system includes a programmable ramp generator which introduces a time varying signal simulating a time dependent state variable, e.g., pressure, temperature, flow rate, etc., to a protection system such as used in a nuclear reactor power plant.  The verification system further includes means for measuring and displaying the response of the protection system to input signal variation over time.  The verification system and method ensures that the protection system outputs an appropriate control signal, such as a shutdown signal, for terminating nuclear reactor power plant operation when the magnitude or time dependent variation of the state variable is not within predetermined limits.

Title: Memory address generation apparatus
Inventor: EINARSON JEFFREY W
IPC: G06F13/16
Filed: 1988-07-28
Granted: 1992-06-30
Abstract: ABSTRACT        Address generating apparatus for use in a computer system which includes a bus processor , a memory requiring 24-bit addresses, and a plurality of I/O processors, some of which generate 22-bit addresses and others of which generate 24-bit addresses on a system bus connecting them with the memory.  The apparatus provides a 2-bit prefix to the address on the system bus when the address on the bus comes from a 22-bit device.  The 22-bit devices are specified by a mask register  and the prefixes by a set of prefix registers , one for each of the devices.  When bus grant logic in the computer system determines which of the devices is to have control of the system bus, logic in the address generating apparatus determines from the mask register whether the device which is to receive control requires a prefix.  If it does, the address generating apparatus outputs the device's prefix to the system bus's two most significant address lines at the same time as the device outputs a 22-bit address to the remaining address lines.  The mask register and the prefix register are loadable from the bus processor by means of a bus  which is independent of the system bus.  On system initialization, the bus processor loads the mask register as required for the I/O devices on the system.  During system operation, the bus processor loads prefixes for 22-bit devices as required for the devices to generate addresses for the area of memory from or to which the device is transferring data.

Title: Coffee brewer
Inventor: KING ALAN M
IPC: A47J31/40
Filed: 1988-08-29
Granted: 1992-02-25
Abstract: ABSTRACT           A beverage brewing machine which has upper and lower brewing chambers which are movable relative to each other so as to clamp a strip-shaped filter therebetween during the brewing process and the chambers can be separated so as to allow the filter strip to be removed from the brewing chamber and the beverage residual wiped therefrom after which the filter strip is returned to the brewing chambers which are then resealed for the next cycle.  A hold down grid engages the top surface of the filter to hold it down as a piston moves in the lower chamber upwardly to force air through the filter to agitate the beverage.  When the piston reaches top dead center, the hold down grid is lifted.  When the piston passes the opening the brewed coffee is poured.  A loose connection is provided between the connecting rod for the piston and the driving crank arm so that the piston remains longer at the top and bottom of its stroke.  Due to agitation of ground and oxygenation of the mixture, or a combination of both, by adding a high volume of air during the brewing process, increased extraction results.

Abstract: Abstract of the Disclosure Non-continuous   reflective   holograms   or diffraction gratings are provided in various forms for authenticating documents and things, and for decorative and product packaging applications.   In one specific authentication  application,   such  a  hologram  or diffraction grating is firmly attached to a surface that contains visual information desired to be protected from alteration.    Examples  of  such  information  include written personal data and photograph on a passport, driver's license,  identity card and the like.   The reflective discontinuous hologram is formed in a pattern that both permits viewing the protected information through it and the viewing of an authenticating image or other light pattern reconstructed from it in reflection. In another specific authentication application, a non-transparent structure of two side-by-side non-continuous holograms or diffraction patterns, each reconstructing a separate image or other light pattern, increases the difficulty of counterfeiting the structure.

Title: Process for the production and purification of succinic acid
Inventor: GLASSNER DAVID A
IPC: C07C55/10
Filed: 1989-09-25
Granted: 1995-02-28
Abstract: A process for producing and purifying succinic acid comprises growing a succinate salt-producing micro-organism on an inexpensive substrate containing carbohydrate, other nutrients, sodium ions and tryptophan under a CO2 partial pressure until most of the carbohydrate is converted to succinate.  The fermentation broth is then electrodialyzed to recover and concentrate the succinate salt in an aqueous stream which is subjected to water-splitting electrodialysis to form base and a succinic acid product.  The resulting succinic acid product is treated first with a strongly acidic ion exchanger in the acid form to remove any sodium or other cations and then treated with a weakly basic ion exchanger in the free base form to remove any sulfate ions or sulfuric acid and to obtain a highly purified succinic acid product.
