Abstract: In such a multi-processor system, a master unit may be connected to a number of slave units each programmed to carry out a particular function, and in turn each of these slave units may be connected as a master to its own set of slave units, again each programmed to perform a particular function; the whole system being co-ordinated and controlled by the original master unit. 
     This disclosure relates to a modular data processing unit adapted to form part of a processing system comprising a plurality of such processing units connected in master-slave relationship. Each processing unit comprises a control section responsive to a control instruction to perform the execution of a programme stored therein and to switch the processing unit to an idle mode on completion of the programme execution, an internal memory section including an area of read/write memory: a computation section for performing calculations in accordance with the programme instructions during which it can access the internal memory; and interface means through which the processor unit can be connected as a master unit to one or more slave units to monitor and control, and to access the internal memories of the slave units while it is executing a programme, and through which it can be connected as a slave to a master processing unit by which it can thus be monitored and controlled, and have its internal read/write memory accessed.

Abstract: A low-inertia scanning system for projecting an image of a stationary object (31) on a flat platen (10) onto a rotating photoreceptor drum (16). An aperture plate (14) located adjacent the photoreceptor drum (16) moves in a direction opposite the direction of rotation of the drum. A carriage (22) disposed between a stationary lens (12) and the photoreceptor drum (16) supports a pair of mirrors (24,26). The light image is projected from the lens (12) to one (24) of the pair of mirrors (24,26) for reflection to the second mirror (26) rotating about a pivot point (30) to scan the image through the aperture (15) onto the photoreceptor drum (16). During scanning of the platen (10), the carriage (22) moves in a linear direction towards and away from the photoreceptor drum (16) and, together with the rotation of the second mirror (26), maintains a constant magnification ratio. A second pair of mirrors (18,19) disposed between the platen (10) and the lens (12) is adapted for movement in a linear direction with respect to the flat platen (10) to predetermined positions in cooperation with the shifting of the lens (12) to provide a properly-focused light image in a different magnification range.

Abstract: The arrangement comprises a telecontrol and a circuit adapted to receive the signals emitted by the telecontrol transmitter and to effect in dependance thereon the switching over between two or more antennas. 
     This circuit consists in its simplest configuration of two antenna taps, each followed by a transistor stage through two diodes leading to a single output to be connected to the antenna tap of the television set. 
     The two transistor stages and the two diodes are alternatively driven on or off so that when the signal from the one antenna passes freely the signal from the other antenna is cut off. 
     The voltages for driving the one stage on and the other stage off respectively, are provided by a control logic driven by a telecontrol signal which can be an already existing signal intended for other functions.

Abstract: Fluides d'epaississement par cisaillement se composant d'un materiau qui se gonfle a l'eau (par exemple de l'argile), capable de former rapidement une pate possedant une resistance d'au moins 1000 Pa avec la solution aqueuse utilisee et present en une concentration suffisante pour former une telle pate, d'un materiau hydrophobe non aqueux comprenant un materiau hydrocarbure et un agent tensio-actif et/ou un agent de renforcement, et une solution aqueuse comprenant de l'eau et un polymere soluble et pouvant se gonfler dans l'eau. L'argile et la solution de polymere et d'eau sont maintenus separes par une phase intermediaire d'un agent tensio-actif a hydrocarbure. Selon un mode d'execution prefere, l'argile encapsulee par la phase d'agent tensio-actif hydrocarbure (phase huileuse) est en suspension dans une phase continue comprenant la phase polymere-eau; toutefois, une suspension d'argile et des gouttelettes de polymere d'eau discretes et separees dans une phase d'huile continue sont aussi possibles au meme titre que des compositions appelees communement "emulsions doubles", aussi bien que des systemes qui sont bi-continus. La phase d'huile intermediaire empeche l'interaction entre la phase polymere-eau et les phases d'argile et donne un materiau composite stable, ne reagissant pas, qui peut etre pompe jusqu'au moment ou la barriere d'huile est cassee par l'application d'une force de cisaillement suffisamment elevee. Par suite de cette rupture, le materiau se melange et reagit, donnant une pate semi-rigide a haute resistance. Plusieurs problemes relatifs au controle des puits tels que des expulsions de petrole ou de gaz peuvent etre enraye en utilisant le materiau composite decrit ci-dessus. On fait descendre le materiau par pompage dans la conduite du puits. Par suite de l'application d'un cisaillement suffisamment eleve tel que la sortie du composite par les orifices du foret, cisaillement necessaire a la rupture de l'enveloppe d'huile, l'argile et la phase polymere-eau reagissent entre elles, donnant lieu a la

Abstract: A hydraulic trailer brake, especially for tractor-drawn agricultural and forestry trailers, with a brake cylinder (16) arranged on the trailer for actuating the adjusting cams (108) of shoe brakes (102), the piston stroke of the brake cylinder (16) corresponding to a movement of the adjusting cams (108) over double the adjusting angle between the release position and the braking position, and in the two end positions of the piston (40), in which one of the pistons is constantly pressed by a spring (80), the adjusting cams (108) each assuming their braking position, and with a pressure source on the tractor which is connected to the brake cylinder (16) via a brake line (10) equipped with a releasable coupling (12). A valve (61) incorporated in the brake line (10) connects the brake line (10) to a return line (26) to the pressure source, the valve (61) being prestressed into a position in which it maintains the release pressure in the brake line (10). The valve (61) is so connected by means of its adjusting member (67) to the mechanical connection (73) between the tractor and trailer that the prestress (69) of the valve (61) is in the opposite direction to an approach between the tractor and trailer, so that the trailer brake become effective as an overrunning brake. <IMAGE>

Abstract: A postal code pattern video signal obtained by optically scanning the postal code area is converted, by a quantitizing circuit (13), into binary data, i.e. single bit pattern data. The video signal is also converted into multibit pattern data by a A/D converter (14). The single and multibit pattern data are stored in the single and multibit pattern memories (15, 16), respectively. The single bit pattern data is masked by the character detecting circuit (17) to set an address of a mask corresponding to chain characters. The multibit pattern memory (16) is designated by the address, so that the multibit pattern data corresponding to the chained characters is read out. The words of multibit pattern data are accumulated for each line, and the lowest level data is detected from the accumulated data as the connecting portions. At the connecting portion, the chained character is separated.
