Abstract: A method and apparatus (2) suitable for excavating a soil mass and like granular materials in which pressurized gas, preferably air, is provided in a reservoir and directed through appropriate valve (4) and duct means to a converging/diverging nozzle (50) positioned at the exit of the duct means. The nozzle includes a restricted throat section and a diverging transitional section which terminates in an outlet section. The ratio of the area of the outlet section to the area of the throat section is greater than 1.0 and preferably greater than 1.2 or more, while the ratio of reservoir pressure to ambient pressure is greater than about 1.9 and preferably greater than 3.7, whereby a gas stream having a calculated velocity greater than Mach 1, and preferably in excess of Mach 1.5 or more, is produced. The high velocity gas stream infiltrates the soil mass creating fissures and cavities, then stagnates within the cavities and violoently expands to fracture the mass.

Abstract: A check valve is made with a rotationally symmetrical valve body with fluid inlet and outlet holes (23, 33) centered on the axis of symmetry. A circular, flexible diaphragm (40) is held in place inside the valve body by a mounting pin (24) which extends through a hold in the diaphragm. The mounting pin and an opposing mounting pin receptacle (34) are supported by leg (25, 35) protruding inwardly from the inlet and outlet walls of the valve body and bridging over the inlet and outlet holes. The length of the legs determines the position of the diaphragm with respect to the inlet wall against which the diaphragm seals. Thus the opening pressure of the valve is dependent on the length of the legs.

Abstract: A torque tube (50) having a cylindrical body (50a) is characterized by a plurality of key surfaces (50k) which extend radially from the surface (50s) and extend longitudinally from an inboard end (50i) to terminate at an outboard end (50o) in a radius (R3) which defines a transition (50t) into a radially extending rib (50r). The cylindrical body portion between adjacent keys (50k) also extends at the outboard end (50o) into a flange (50f) which is continuous about the outboard end of the tube. The combination of radially extending ribs (50r) and flange (50f) define T-sections at the outboard end (50o) which provide the strength requirements of the torque tube in its intended service application.

Abstract: A transport medium for orderly, in-process transportation of assembled electrical devices (32) during backend processing. A carrier tray is comprised of a plurality of carrier units (4) held in coplanar relationship by a frame (2). Preferably the carrier units (4) are polyethersulfone inserts latchable into a coordinate matrix of carrier unit holes (6) defined by a metallic sheet.

Abstract: A bistable electromechanical transducer is disclosed having an armature (3, 20) reciprocable between first and second positions, a permanent magnet (26) latching arrange­ment for maintaining the armature (3, 20) in the respective positions, and an electromagnetic repulsion arrangement (13, 15) operable when energized to dislodge the armature (3, 20) from the position in which the armature was maintained and causing it to move to the other of the positions. In a preferred embodiment, the transducer takes the form of an electronical­ly controllable valve mechanism for use in an internal combustion engine and has an engine valve (1) with an elongated valve stem (17) along with the electromagnetic repulsion arrange­ment (13, 15) for causing the valve to move in the direction of stem elongation between valve-open and valve-closed positions. An arrangement for decelerating the valve as the valve nears the respective valve-open and valve-closed positions includes as least two separate damping arrange­ments (4, 21, 35, 37) jointly effective to slow valve motion as the valve gets close to said one position. The damping may include dynamic breaking and energy recovery. The mechanism may also include a housing (23) at least partially surrounding the valve stem and an arrangement (49) for circulating the engine liquid coolant through a portion of the housing.

Abstract: A mobile apparatus for chemically decontaminating PCB-contaminated dielectric fluids utilizes three reactors (A,B,C) through which the contaminated fluid is processed on a repetitive, sequential batch basis automated by a programmable controller (64). The processing of each reactor batch includes a charging cycle during which a reactor is filled with contaminated fluid, a reaction cycle during which the PCBs are destroyed by reaction with reagents introduced into a reactor, and a discharging cycle during which the reactor is emptied of decontaminated fluid and reaction by-­products into a decanting tank for ultimate separation. The controller (64 ) co-ordinates the sequential batch processing through the three reactors in 120° time phased relation such that a charging cycle of one reactor batch, a reaction cycle of a second reactor batch and a discharging cycle of the third reactor batch are all coincident in time during normal operation.

Abstract: Le dispositif décrit sert à joindre deux unités de construction, dont l'une (1) supporte la charge et dont l'autre (2) produit la charge. Une solution classique pour joindre par exemple une colonne et une poutre consiste à former dans la colonne une extension dirigée latéralement et destinée à soutenir la poutre. Ce type d'extension complique considérablement l'opération de coulée de la colonne et est à l'origine de forces de cisaillement importantes qui se forment dans la colonne. Dans la présente invention, on élimine ces inconvénients en fixant aux unités de construction (1, 2) des organes d'ancrage (3, 4) qui ne sont pas saillants par rapport à la colonne, du moins pas par rapport à ses surfaces latérales, et en les plaçant dans les unités de construction dans une position telle que les points, au niveau desquels les organes d'ancrage s'étendant d'une unité de construction à l'autre sont fixés aux unités de construction, sont situés dans un joint terminé à une certaine distance les uns des autres dans le sens vertical.

Abstract: Un processus continu, notamment le contrôle qualité de la production de bandes de papier, est surveillé et analysé de manière continue et avec une haute résolution afin de détecter des défauts, malgré le fait que le traitement de signaux nécessaire à une telle surveillance et à une telle analyse de haute résolution requiert le traitement des données à des débits énormes (par exemple, des milliards de calculs par seconde). Le système utilise une architecture informatique de traitement continu des données en temps réel. A un premier niveau de l'architecture, les signaux reçus du processus (par le balayage de lignes sucessives sur le papier) sont numérisés et réduits de façon à représenter des données correspondantes à certains événements, tels que des défauts de la bande. A un deuxième niveau de l'architecture, une rangée de processus parallèles traite simultanément et continuellement les données réduites afin de fournir des sorties qui caractérisent les événements, par exemple, des mesures concernant la localisation et l'extension des défauts de la bande. A un troisième niveau, les données du deuxième niveau sont analysées afin de fournir des sorties qui représentent l'analyse des défauts du processus représentés par les événements. Ces sorties sont utilisées pour commander le processus ou pour donner des informations au sujet de la source des défauts, assurant ainsi la production d'un matériau exclusivement de haute qualité.

Abstract: The absolute position encoder comprises a rotary code plate for producing sinusoidal wave outputs onto several of channels, each output having a different number of cycles per revolution. An AD converter converts the sinusoidal outputs on the channels into digital signals to constitute rotary angle data of the code plate, and a ROM stores the data in which are interpolated the angle data within a wavelength of the channel. The ROM stores the interpolated data of lower channels having large numbers of cycles as address data for correction. The ROM also stores data obtained by correcting the interpolation errors contained in the interpolated data of upper channels having small numbers of cycles, all at corresponding addresses. The absolute position of a moving member is detected by combining the interpolated data read by address data of the lower most channel having the largest number of cycles and the corrected data of the channels higher than the lowermost channel read based on the address data for correction.
