Abstract: A self learn technique for a circuit tester such as a manufacturing defect analyser involves grounding each and every node on a known good circuit board, discharging two chosen nodes, applying a stimulus voltage to one of the chosen nodes, removing the grounding from the second chosen node and monitoring the voltage developed on the second node. By comparing the voltage with a threshold value a component can be identified between the nodes. By repeating the procedure over all pairs of nodes the circuit tester can learn component positions and types on the board.

Abstract: A thermal transfer dyesheet, comprising a supportive base material coated with a composition of a thermally transferable dye dispersed uniformly throughout a polymeric binder matrix, also contains in its coating composition a crystallisation inhibitor having a molecular structure consisting essentially of a polymer backbone to which are chemically bonded a multiplicity of groups having substantially the same shape, charge distribution and hydrogen bonding pattern as the dye or substantial portion thereof. Provision of such crystallisation inhibitors serves to reduce the problems of roughness on the dyesheet surface, and the dirty surfaces which both have tended to occur in previous dyesheets as the dye molecules migrate to the surface and combine to form crystals there.

Abstract: In a method of operating a processor array system mapping vectors defining an initial ordering of data in the processor array and a different desired ordering are read. At least two transformation sequences are generated. Each step of each transformation sequence comprises a movement of data in the array corresponding to an operation on elements of a mapping vector. The transformation sequences are costed and the sequence of least cost identified and executed. The cost of a transformation sequence is determined by the time taken to execute that sequence. In a preferred embodiment the processor array system comprises a host processor (1) and a processor array (2) and the host processor (1) reads the mapping vectors and generates the transformation sequences which are executed by the processor array (2).

Title: Earth boring apparatus with control valve
IPC: E21B4/14
Filed: 1988-12-19
Granted: 1993-08-04
Abstract: An earth boring apparatus has a pneumatically operated earth boring tool, a flexible conduit or drill pipe connected to the tool and to a source of pneumatic fluid. The tool has an earth boring member and a reciprocally movable hammer positioned in the tool to apply a percussive force. A valve assembly in the flexible conduit or drill pipe substantially adjacent to the tool between the tool and the source of pneumatic fluid controls the flow of pneumatic fluid to the tool in response to the pressure of pneumatic fluid in the flexible conduit or drill pipe permitting the valve to be opened to permit flow of pneumatic fluid to the tool at a predetermined operating pressure to transmit an initial pulse of pneumatic fluid to initiate operation of the hammer. The valve is kept open at a lower pressure than that required to open it. One form of the valve is a pressure operated valve, spring-loaded toward closed position, opened at a first predetermined pneumatic pressure permitting flow to said tool and closed at a second, substantially lower, pneumatic pressure. Another form of the valve includes a valve, spring-loaded toward closed position, which opens in response to pneumatic conduit pressure, and spring loaded ball detents or a pneumatic pressure operated latch to secure the valve in an open position. The latch and valve are operated to closed position at a lower pressure.

Abstract: Le second niveau (10) d'une servosoupape régulatrice de débit à sécurité intégrée possède un boisseau (12) à cinq bossages monté coulissant dans un alésage (19) de corps. A zéro, les bossages terminaux (41, 45) sont pratiquement en position neutre par rapport aux fentes de pression d'alimentation (22, 26), le bossage médian (43) est pratiquement en position neutre par rapport à une paire de fentes de retour (23, 24), et les bossages régulateurs intermédiaires (42, 45) sont tous deux symétriquement en position non juxtaposée par rapport à leurs fentes régulatrices associées (29, 30). Des butées (34, 35) limitent le déplacement du boisseau dans chaque sens axial. Lorsque le boisseau est en position zéro ou bien dans l'une ou l'autre des positions extrêmes, l'écoulement souhaité par rapport aux fentes régulatrices est bloqué, et les fuites relatives sont régulées. On peut équilibrer ces écoulements de fuite de manière à obtenir un débit de fuite net pratiquement nul par rapport à chaque fente régulatrice. Dans une variante, on peut délibérément faire varier lesdits écoulements les uns par rapport aux autres en vue d'obtenir le débit de fuite net souhaité par rapport aux fentes régulatrices.

Title: Skin diving snorkel
IPC: B63C11/16
Filed: 1989-12-27
Granted: 1993-02-10
Abstract: A skin diving snorkel has a chamber (18) housing a normally closed float valve (26) in series with an outwardly directed purge valve (22-24). A mouthpiece (20) adjacent and above the chamber (18) provides a flow path from the conduit (12) to the interior of the diver's mouth. The float valve (26) opens when the chamber (18) is flooded with water. Consequently, water in the snorkel which extends above the ambient water surface (16) will drain through the purge valve (22-24), decreasing the amount of water remaining within the snorkel to be purged. The float valve (26) blocks flow through the purge valve (22-24) when the chamber (18) is emptied of water during a purging exhalation, preventing the wasteful loss of purging air. Water which accumulates in the chamber (18) between purges is eliminated when the snorkel is next purged.

Abstract: Dispositif de guidage de fil-électrode pour machines d'étincelage par fil, permettant de supporter avec une précision constante un fil électrode sur une trajectoire d'avance déterminée pendant l'usinage par étincelage, afin d'améliorer la précision d'usinage. Le dispositif de guidage de fil-électrode (1) est pourvu d'une soupape de commutation (80) qui permet ou interrompt l'alimentation en air sous pression d'un actuateur pneumatique (70) qui entraîne un bloc mobile (40) assurant le support en trois points du fil-électrode (3) entre ce même élément et un bloc de fixation. Pendant la connexion automatique du fil, un orifice d'alimentation en air sous pression (88) et un orifice de commutation (87) dans la soupape de commutation sont en communication entre eux pour alimenter l'actuateur en air sous pression, de sorte qu'une bielle (73) quitte le bloc mobile (40) pour libérer une force de sollicitation qui lui est appliquée, et le fil-électrode peut être introduit entre le bloc de fixation et le bloc mobile. Pendant l'usinage par étincelage, l'orifice de commutation est isolé de l'orifice d'alimentation en air sous pression et l'alimentation de l'actuateur en air sous pression est interrompue, de sorte que l'actuateur sollicite le bloc mobile pour supporter le fil. Un liquide d'usinage à haute pression éjecté par un ajutage (51) pour pénétrer dans l'actuateur à travers des interstices entre les unités respectives est déchargé à l'extérieur par un orifiice de détente (89), ce qui empêche toute diminution de la force de sollicitation que l'actuateur applique sur le bloc mobile. Cet agencement permet de supporter avec précision le fil-électrode sur la trajectoire d'avance déterminée.

Abstract: La présente invention utilise la régulation de l'enthalpie spécifique à l'entrée de l'évaporateur par utilisation délibérée de la pression et/ou de la température avant l'étranglement pour obtenir un réglage de la capacité. La capacité est réglée par variation de la différence d'enthalpie du réfrigérant dans l'évaporateur et par modification de l'enthalpie spécifique du réfrigérant avant l'étranglement. En état surcritique, ce réglage peut être assuré par variation de la pression et de la température séparément. Dans un mode de réalisation préféré, cette modulation de l'enthalpie spécifique est effectuée par variation de la pression avant étranglement. Le réfrigérant est refroidi à une température aussi basse qu'il est possible de descendre au moyen du milieu de refroidissement disponible et la pression est régulée pour produire l'enthalpie requise. Dans un autre mode de réalisation, on utilise la modulation de l'enthalpie par variation de la température du réfrigérant avant étranglement, ce qui est effectué par réglage du rejet de chaleur depuis le dispositif.

Title: Pneumatic shoe for high speed filamentary capstan
IPC: B65H57/04
Filed: 1989-09-28
Granted: 1993-08-11
Abstract: An apparatus and methodology for uniformly applying a compressive force against a filament to pneumatically drive the filament or fiber optic cable against a capstan without any concentrated amount of stress at any point on the filament (12) is effectuated by pneumatically forcing the filament (12) into an equatorial V-groove (46) defined in the capstan (16). Pneumatic pressure is applied to a predefined segment of the capstan (16) by a pneumatic shoe (10) having an internal shoe pressure chamber (20). The pressurized gas or air is applied to the segment from the chamber (20) into the proximity of the equatorial V-groove (46) on the capstan (16). The V-groove (46) is vented to atmosphere so that the filament (12) is forced or blown into the V-groove (46). Side and end clearances between the rotating capstan and the shoe are sized to allow the viscosity of the pressurized gas to operate to retard the escape of the pressurized gas from the predefined segment of the capstan (16). Utilizing such an arrangement, approximately 10 kilometers or more of filament can be 20 paid out in approximately 32 seconds or less.
