Abstract: A wobble plate compressor with a variable displacement mechanism includes a compressor housing (3) which is provided with a crank chamber (32) and a cylinder block (31) in which a plurality of cylinders (33) are formed. A drive shaft (7) is rotatably supported in the housing. A rotor (9) is fixed on the drive shaft (7) and variably connected to an inclined plate (11) through a hinge mechanism which includes a first arm portion (93) which is formed on either one of the rotor or inclined plate, a second arm portion (114) which is provided with an elongate hole (115) formed on the other thereof and a guide pin (12) which is fixedly disposed in a hole which is formed through the first arm portion. A wobble plate (13) is adjacent (8) the inclined plate and converts rotary motion of the inclined plate into nutating motion thereof. A plurality of pistons (19) are coupled with the wobble plate through a plurality of connecting rods (18) each of which is reciprocably fitted within a respective one of the cylinders and of which the stroke volume is changed in accordance with variation of the angle of the inclined plate. The elongate hole is shaped so that a top clearance of the piston provides the least volume at the time that the angle of the inclined plate is largest, and the top clearance of the piston provides the largest volume at the time that the angle of the inclined plate is smallest. Therefore, even though the range of inclination of the angle of the inclined plate is narrow, a wide range of control of the displacement volume of the compressor can be accomplished.

Abstract: A laser amplifier operable such that at the commencement of each output pulse the carrier level has receovered from depletion by the previous pulse. Under these conditions output power commensurate with a much high carier density than is usually available is possible. The mode of operation is especially useful as a way of providing high power pulses, for example for use in optical time demain reflectometry. Using a travelling wave amplifier in conjunction with return to zero formate data pulses is also disclosed.

Abstract: A safety device is described to prevent inciden­tal opening of the control knobs in electric or gas-kit­chens, hobs or ovens. This safety device is actuated when the top cover is lowered to a position of closure as each control knob to be locked at an "OFF" position is integrally formed with a shaped cam coincident, at this position, with an opening in a sliding plate which is movable along a first direction upon rotation of at least one knob to the "ON" direction. A spring biases said slider to the opposed direction when all the knobs are "OFF", there being also provided, integral­ly with the cover, means cooperating, when the latter is lowered, with a means for preventing said movement of the slider which is thus locked at the position corresponding to all the knobs being "OFF". Otherwise an "ON" position of at least one knob shifts the slider so as to impede the complete lowering of the cover, through said integral means. There may also be provided visual safety means such as light signals associated with the position of said slider or actual locks either to keep the cover lowered or the slider at the position corresponding to all the knobs being "OFF".

Abstract: Un système d'alimentation de réserve pour lampes fluorescentes ou autres lampes luminescentes à gaz fournit de l'énergie à une des lampes lorsque l'énergie normale du réseau du courant alternatif n'est pas disponible. Le circuit fonctionne avec un appareil fixe d'éclairage standard contenant deux ou plusieurs lampes fluorescentes. Lorsque le courant du réseau à courant alternatif est disponible, les deux lampes fonctionnent de sorte que l'appareil d'éclairage produit une luminosité maximale. Le courant du réseau à courant alternatif fournit également une charge de maintien à une batterie à basse tension contenue dans l'appareil d'éclairage. Lorsque le courant du réseau n'est pas disponible, la batterie maintien uniquement une des lampes allumée. Par conséquent, bien que l'appareil d'éclairage produise une sortie réduite, la vie de la batterie est augmentée. Dans un mode de réalisation, les deux lampes fluorescentes sont directement alimentées en énergie par la ligne de courant alternatif lorsque l'énergie de courant alternatif n'est pas disponible, un relais déconnecte la ligne à courant alternatif des deux lampes et connecte une lampe à un inverseur CC/CA alimenté en énergie par la batterie interne. Dans un autre mode de réalisation, l'énergie est fournie directement à une lampe par la ligne à CA et à l'autre lampe par un inverseur CC/CA qui reçoit l'énergie soit directement d'une alimentation en CC qui fonctionne séparément de la ligne à CA ou par une batterie interne à basse tension. Dans un troisième mode de réalisation, pendant des conditions normales de fonctionnement l'énergie est fournie aux deux lampes par des inverseurs séparés CC/CA alimentés par une alimentation séparée de la ligne à CA. Lorsque la tension du CA n'est pas présente, l'inverseur CC/CA d'une lampe est alimenté par la batterie interne à basse tension.

Abstract: Une soupape pour un récipient de stérilisation comprend un corps élastique de support (26) ayant la forme d'une capsule de compression qui maintient la soupape (18) dans la position d'ouverture. Cette capsule de compression (26) est en communication avec l'intérieur d'une garniture (44) sur laquelle le couvercle de la soupae (18) est posé de manière étanche et qui présente un orifice de soupape (62) susceptible d'être fermé par le bouchon (64) d'un organe de réglage (68). La fermeture se fait, une fois que la température de stérilisation est atteinte, au moyen d'un organe (68) de réglage de la température comprenant un alliage qui se fond lorsque la température de stérilisation est atteinte. A son état solide, l'alliage retient l'organe de réglage préarmé par un ressort, et laisse celui-ci se déplacer lorsqu'il est à l'état fondu. Un raccord unidirectionnel permet de serrer l'organe de réglage lorsque l'alliage est à l'état solide.

Abstract: A hydraulic setting tool for packers comprises a case (28) with a ball valve (140) therein, a bypass passageway (202) for bypassing around the ball valve when the ball valve is in a closed position, a fill valve (210) for closing the bypass passageway when desired, and a packer setting sleeve (270) for hydraulically setting a packer attached below the setting tool. The fill valve is preferably characterized by a sliding sleeve valve annularly disposed on a stationary mandrel (144) in the case and is movable in response to a pressure in the tool. The packer setting sleeve is attached to a setting piston which may be actuated in response to a first differential pressure between the tool string and a well annulus. A slidable mandrel (62) is provided in operative association with the ball valve and is movable in response to a second differential pressure between the well annulus and the tool string. The second differential pressure also acts to raise the setting piston and setting sleeve to a retracted position spaced away from the packer.
