Title: Method for monitoring gasket compression during fastener tensioning
IPC: F16J15/00
Filed: 1989-07-14
Abstract: A method is described for tensioning large bolts (16) used in securing covers (12) for openings in pressure vessels, pipe couplings, valves and the like, in which a sealing gasket (18) is used. The method is designed to prevent leakage in gasketed connections by monitoring the interaction of bolt tension and gasket compression. The method is particularly concerned with determining the bolt tension at which full gasket compression is achieved. This allows the user to verify proper gasket density, proper gasket seating, and proper bolt preload. The method involves measuring changes in a dimension (E) related to gasket compression as bolt tension (F) is increased. Full gasket compression to a metal compression stop is noted as a sharp change in the ratio  DELTA E/ DELTA F. A secondary method of identifying the point of full gasket compression utilizing acoustic transmission is described. The secondary method may be used to verify the results of the first method.

Abstract: Un thermomètre infrarouge (10) à ouverture fixe (99), possède une tête de lecture à focalisation à distance (12) qui permet la transmission de la lumière infrarouge (16) d'une cible (14) vers un photocapteur (52) d'une tête à détecteur à défocalisation (20). La tête de lecture à distance possède une lentille de remise en image (84) et un dispositif de réglage sélectif de la netteté de la lentille (84) par rapport à la cible (14) suite au montage fixe de la tête de lecture. Le réglage de l'ouverture est maintenu fixe pendant le réglage de la netteté de manière à éliminer la nécessité de recalibrer suite au réglage de la netteté. La tête à détecteur à défocalisation (20) possède une lentille de retransmission à défocalisation (50) qui est sélectivement défocalisée pour permettre la transmission d'une image légèrement floue et défocalisée depuis l'extrémité de sortie d'un câble à fibre optique (18) vers le photocapteur (52) afin de réduire le bruit, établir la moyenne du signal lumineux et réduire les difficultés de calibrage dues aux tâches à haute intensité dans le champ d'image et afin de rendre l'unité moins susceptible à la mauvaise focalisation. La précison est d'autant plus améliorée par le fait que l'on utilise un diaphragme de champ (86) muni d'une fente étroite, par exemple, permettant le passage de la lumière seulement à des zones déterminées de l'extrémité d'entrée du câble à fibre optique (18) qui constitue le champ optique.

Title: Motion picture digital sound system and method with primary sound storage edit capability.
Inventor: BEARD TERRY D
IPC: G11B20/00
Filed: 1993-08-02
Abstract: A digital sound system for motion picture films employs a digital time code on the film to trigger the transfer of sound data from a digital audio store to a FIFO memory. The digital audio data is read out from the FIFO memory and played back in the theater at a constant rate, with any jumps in the digital time code handled by making a corresponding jump within the digital audio store but not in the FIFO memory. Readout from the FIFO memory and clocking of the digital-to-analog converters (DACs) used for theater playback is synchronized to the AC mains that powers the theater projector, and thus allows for an uninterrupted audio playback even if time code entries on the film are obliterated. The FIFO memory need only have enough capacity to accommodate the maximum audio store access time, and can be quite small.

Title: Field effect transistor with switchable body to source connection
Inventor: MOYER JAMES C
IPC: B29C35/08
Filed: 1994-09-16
Abstract: To avoid forward biasing the diodes within an N-channel transistor, the body (36) and source (38) of the N-channel transistor (34) are switchably connected via a high-voltage FET (42). The gates (46, 50) of the N-channel transistor (34) and high-voltage transistor (42) are connected together so that both transistors are on or off simultaneously. When both transistors are on, the high-voltage transistor (42) shorts the body (36) and source (38) of the N-channel transistor (34). When both transistors are off, the body (36) and source (38) of the N-channel transistor (34) are disconnected and a third transistor (56) couples the body to a reference potential. The N-channel transistor (34) and high voltage transistor (42) share a common body in a semiconductor substrate. The source (38) of the N-channel transistor (34) provides an output terminal for the circuit. A number of these devices, each connected to a different supply voltage, can be connected to the same output terminal and selectively energized to form a voltage multiplexer.

Title: Separating and concentrating certain ions using ion-binding ligands bonded to membranes
Inventor: TARBET BRYON J
IPC: C08J5/22
Filed: 1995-04-25
Abstract: A method for removing, separating, and concentrating certain selected ions from a source solution that may contain larger concentrations of other ions comprises bringing the source solution in contact with a composition comprising an ion-binding ligand covalently bonded to a membrane having hydrophilic surface properties. The ligand portion of the composition has affinity for and forms a complex with the selected ions, thereby removing them from the source solution. The selected ions are then removed from the composition through contact with a much smaller volume of a receiving solution in which the selected ions are either soluble or which has greater affinity for the selected ions than does the ligand portion of the composition, thereby quantitatively stripping the complexed ions from the ligand and recovering them in concentrated form in the receiving solution. The concentrated ions thus removed may be further separated and recovered by known methods. The process is useful in the removal of selected ions, including noble metals and other transition metals from a variety of source solutions such as are encountered in semiconductor, nuclear waste cleanup, metals refining, environmental cleanup, providing ultra high purity fluids, electric power, and other industrial enterprises. The invention is also drawn to the ligand-membrane compositions.
