IPC: G06F9/44
Filed: 1990-01-24
Abstract: High-speed inference method and system for a production system represented by an expert system. A knowledge base (16-3) comprised of a rule and a fact possessing a plurality of attributes is converted into machine language instructions executable by a processor (16-1) to execute inference. The machine language instruction of the fact has the function of transferring a value of the fact to a specified location and the machine language instruction of the rule has the function of performing matching decision by referring to the specified location. The number of pattern matching operations can be decreased and the interpretation overhead can be reduced to ensure high-speed inference.

Abstract: Broche d'attache, permettant de fixer les extrémités libres d'un foulard ou d'une cravate à un habit sur lequel est piqué la broche, qui comprend un élément de base allongé (10) muni d'une épingle à ressort plié montée de manière pivotante (12) et d'un fermoir (13), et des ailes d'accrochage semi-circulaires (14 et 15) disposées de manière espacée de chaque côté de l'élément de base. Les surfaces d'accrochage des ailes faisant face à l'habit (10) sont sensiblement sur le même plan que la surface de l'élément de base qui est du côté opposé à l'habit (17), de sorte que les extrémités du foulard ou similaire passent en serpentant sous l'une des ailes, par dessus l'élément de base, puis sous l'autre aile. Le foulard ou similaire ne peut donc s'échapper de lui-même de la broche et reste fixé en place par la friction entre le foulard ou similaire et l'habit aux endroits où les surfaces d'accrochage des ailes faisant face à l'habit appuient sur le tissu du foulard. Grâce à cet objet, on peut fixer fermement un foulard même très léger sur un habit sans risque de l'endommager.

Title: Dosing system and method.
Inventor: PLESTER GEORGE
IPC: B67D1/00
Filed: 1990-09-19
Abstract: A dosing system has a vessel for holding a fluid and a dosing device for dispensing a measured quantity of fluid from the vessel. The dosing device hermetically seals the vessel and has a valve with a fluid passage, a piston surrounding the valve and a cylinder housing surrounding the piston. The valve is positioned in a first position wherein fluid is gravity fed from the vessel to a chamber formed between a drive face of the piston and the cylinder housing. The valve can be reciprocated from the first position to a second position whereat the valve closes the inlet from the vessel to the chamber. The piston closes the passage within the valve when the valve is in the first position and opens the passage when the valve is moved to the second position to permit discharge of fluid from the chamber. When the valve moves to a third position, the drive face of the piston moves toward a shoulder of the cylinder housing to thereby pump the fluid from the chamber. The valve can be moved between these three positions to repeatedly discharge fluid. When the valve returns from the third through the second to the first position, the drive face of the piston will move away from the shoulder of the cylinder creating suction in the chamber. This suction will assist in the gravity feed of fluid from the vessel to the chamber. The dosing system is particularly useful in a dispenser for a beverage and the vessel can be a bag-in-box container. A pliable funnel portion is provided between the vessel and the dosing device whereby the dosing device may be pushed into or pulled from the vessel.

Abstract: A variable impedance device comprises a coil (10) and an associated magnetic circuit (16) having a gap receiving a plate (20) of superconducting material which acts as a shield or barrier so that, while the plate (20) is in its superconducting state, magnetic flux is caused to traverse the gap via pathways substantially greater in length than the width of the gap. If a large current is passed through the coil (10), the plate (20) becomes resistive thereby presenting a substantially increased impedance to the current. The device may be used in current limiting applications, or other applications where a variable impedance is required.
