Abstract: A torque wrench comprises a split casing (10) which can be divided to receive and grip pipes, each casing half (10a,10b) comprising jaws (14) which are synchronously movable to center and frictionally engage the pipe joints. The wrench has a split inner annulus (12a,12b) which is mounted in and connected to a split intermediate annulus (11a,11b) which is rotatably mounted in the split casing (10). Inner annulus (12) is provided with at least two activable and displaceable clamping jaws (14) and furthermore, means are (21,22,23,16) provided for temporary and external transfer of a controlled torque to intermediate annulus (11).

Inventor: KERR RICHARD J
IPC: H03M1/04
Filed: 1988-12-08
Abstract: A method and apparatus for reducing spurious output noise in digital frequency synthesizers employing sine amplitude converters connected to Digital-to-Analog converters to generate analog waveforms from sine amplitude data. Random or pseudorandom numbers having a value equal to or less than plus or minus one-half of a minimum quantization step or value change for the sine amplitude data are generated and added to the sine amplitude data with the resulting sum being transferred to the Digital-to-Analog converter. In one embodiment, a summation circuit is connected between an output of the sine function converter and an input of the Digital-to-Analog converter and also has a second input connected to a pseudorandom number generator which provides Pseudorandom numbers varying in value over a range of +/-1/2n+1 times a least significant step value, or bit for base 2, of a corresponding Digital-to-Analog input data value where n is greater than or equal to 1.

Abstract: On a mis au point un milieu de gain à semi-conducteur résonnant aux longueurs d'ondes. La caractéristique essentielle de ce milieu est une multiplicité de régions de gain à puits quantique (1) séparées par des régions d'espacement à semi-conducteur de largeur de bande interdite supérieure. Chaque période de ce milieu se compose d'une région à puits quantique, et l'on choisit la région d'espacement adjacent de sorte que la largeur totale soit égale à un multiple entier d'une demi-longueur d'onde dans le milieu du rayonnement avec lequel le milieu est en interaction. L'invention décrit également le pompage optique, le pompage par faisceau électronique et le pompage électrique du milieu. On peut utiliser ce milieu comme milieu laser pour des dispositifs ou des agencements individuels, avec ou sans réflecteurs, pouvant être soit à semi-conducteur soit externe.

Abstract: The method for bidirectional data transmission according to the time-division principle enables the synchronisation of plesiochronously running packet timing signals with no increase in the data stream jitter component which normally occurs. Two bidirectionally and continuously running, plesiochronously clocked data streams (S12, S21) are divided up into data packets which are exchanged within cycles (Z) between two transceiver stations (SE1, SE2). The cycles (ZSE1, ZSE2) plesiochronously running in both stations (SE1, SE2) are synchronised through modification as required of the cycle length (ZSE2) and corresponding modification of the packet length of the data packets transmitted from station (SE2) to station (SE1). A circuit arrangement is furthermore indicated for carrying out the method. <IMAGE>

Abstract: A knock down bulk container (10) has side and end panels (24,25,18) hinged to a base (11). In assembling the container (10) for use, first the end panels (18) are uprighted to a substantially vertical position, and then the side panels (24,25) are swung to an upright position. As the side panels (24,25) are swung into their upright position, lift pins (38) formed to protrude laterally outwardly from each side edge of the side panels engage a lift track (50) in an end wall (14) of the base (11) to raise each of the side panels (24,25) vertically with respect to its hinge axis. To connect the panels together, the end panels (18) are formed with pockets (43) along their edges adjacent the corners of the container, and the side panels (24,25) have hooks (54) that are seated within the pockets (43) of the end panels (18). As the side panels (24,25) are swung into their upright position, the hooks (54) are positioned vertically above the pockets (43) by the engagement of the lift pins (38) with the tracks (50). Once in the vertical position, the lift pins (38) disengage from the tracks (50) and the side panels (24,25) drop downwardly to seat the hooks (54) within the pockets (43) to form the corners of the container.
