Title: Torque control device for a nut runner
IPC: B25B21/00
Filed: 1972-11-27
Abstract: 1353573 Torque control of nut-runners ATLAS COPCO AB 27 Nov 1972 [25 Nov 1971] 54689/72 Heading B3N A combination of a torque controldevice (s) 13, 14 and a nut runner(s) 11, 12 with a housing and a motor therein connected to a drive spindle 34 comprises a frame 15 in which the nut runner(s) is mounted, a pressure fluid loaded piston device(s) connected to an adjustable pressure regulator 42 and coupled between a nut runner and the frame for transmiting the reaction torque from the nut runner to the frame, and means to shut off the motor of the nut runner(s) in response to a yielding movement of said piston device(s). Fig. 1 shows two nut runners on frame 15. Air passes from regulator 42 along conduits 29 into chamber 28 and from thence through valve 36, 31 to conduit 32 and the motor of the respective nut runner. Reaction torque from the nut runner is transmitted by arm 26 to piston 24. Thus in operation at a predetermined torque the piston is moved so that portion 36 engages in bore 31 to shut off air to the motor. This occurs during initial movement of the piston thus allowing the piston enough damping to stop any turning of the. housing of the nut runner. Leak channel 37 is dimensioned so as not completely to compensate for leakage through the motor. Initial movement of the piston vents outlet 38 so that indicator 39 shows tightening to the predetermined torque has oocured. The piston devices may be mounted in parallel with the nut runners. Also instead of direct acting shut-off valves an alternative method is by pilot valves mechanically controlled by the pistons and which in turn pneumatically control shut-off valves in the supply conduits of the motors.

Abstract: 1,173,850. Semi-conductor devices. INTERNATIONAL BUSINESS MACHINES CORP. 20 Nov., 1968 [1 Dec., 1967], No. 54989/68. Heading H1K. In a method of manufacturing a radiationemitting device, having a semi-conductor region wherein recombination radiation is generated in a first frequency band associated with a paired state of acceptor and donor impurities in the semi-conductor region and in a second frequency band associated with a dissociated state of acceptor and donor impurities in the semiconductor region, the device is heat treated within such a temperature range and for such a time that the proportion of impurities in the state which gives rise to a higher efficiency in the required radiation band is increased. In particular in a gallium phosphide semi-conductor region doped with zinc and oxygen to form a PN diode the efficiency of the visible radiation emission can be increased by heat treatment in the range between 450 C. and 700 C. for from 4 minutes to 3 hours. The temperature during the heat treatment need not be constant, but the treatment may proceed in stages at fixed temperature values within the specified range. Other impurities used to dope the semi-conductor are zinc and sulphur, cadmium and oxygen, and carbon and oxygen, the acceptor impurity being present in a higher concentration than the donor impurity.

Abstract: 1,192,759. Active filter. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. 11 March, 1969 [12 Dec., 1967], No. 56413/67. Heading H3T. A transverse line filter employs the delay network of Specification 1,162,871 as delay sections D1 ... Dn. Two outputs are taken from each section D1 to Dn. One output is taken via individual potentiometers P1 ... Pn to a summing amplifier SM, and the other, having left the amplitude of the first, is applied via individual buffer stages B and common amplifier RM to the summing amplifier SM. A complete range of positive and negative control of the amplitude at each tapping point is thereby available. The arrangement may be employed to provide automatic equalization, and once a low error is thus obtained an incoming signal may be delayed and correlated with the decoded signal to provide a control signal to maintain a well defined output.
