Abstract: 1,238,154. Setting anchor nuts. AERPAT A.G. 27 Feb., 1970 [19 March, 1969], No. 9579/70. Heading B3U. [Also in Division F2] A manually-operable tool for installing blind anchor nuts by pulling an internally threaded part 53 into a body part 51 comprises a body member 11 having a handle grip 16, an annular anvil 13 for engaging the nut, an interchangeable threaded mandrel 17 positioned in the aperture of the anvil 13 and a shaft 22 reciprocable by a handle 25 between a first position in which a key 24 on the shaft 22 engages a socket 19 in the mandrel 17 to allow rotation of the mandrel by the handle 25 and a second position in which the shaft 22 is disengaged from the mandrel to allow rotation of the shaft 22 only. In operation, with the shaft 22 engaged with the mandrel 17, the mandrel 17 is screwed into the nut portion 53 by rotating the handle 25 clockwise until a serrated face 14 on the anvil engages the fastener. Thereupon, the handle 25 is further rotated clockwise through a small angle to screw the nut portion 53 towards the anvil 13, after which the shaft 22 is disengaged from the mandrel and rotated anticlockwise through the small angle to its initial position. The shaft is then pushed back into engagement with the mandrel and the steps repeated until the fastener is set. The shaft 22 may be removed from the bore of the body member 11 by giving a sharp pull on the handle 25 to cause balls 34, 35 to be retracted into a bore 36.

Abstract: 1305952 Compensating for supply voltage variations in measuring systems MOSKOVSKY ORDENA LENINA ENERGETICHESKY INSTITUT 7 Aug 1970 38183/70 Heading G1U In order to compensate the output U 1 , Fig. 1, of a transducer, e.g. a differential transformer 1, for variations in supply voltage, a second transducer 2, the non-electic input to which is maintained constant, is arranged in series with the first so that the output U 2  of the second transducer can be regarded as a measure of the supply voltage, and a circuit, comprising a stabilized voltage source 8 of potential U 3 , an adjustable attenuator 3 functioning as the input resistor to an amplifier 15 and a comparator 17, is arranged to produce across a utilization device 19, e.g. a recorder, a potential U 3 U 1 /U 2  , which, since the quotient of U 1  and U 2 , is involved, and U 3  is constant, is dependent of the supply voltage. The circuit operates in two phases. In phase 1, with switches 9 and 10 in their upper positions, the potential U 2  is applied, via the attenuator 3 and the amplifier 15, to one input of the comparator 17, which receives on its other input the output potential U 1  from the first transducer. The attenuator 3 is then adjusted, by sequentially switching into circuit resistors r 1 , r 2 , ..., r n , until the output of the amplifier, say kU 2  (where k will be negative) equals the output U 1  of transducer 1. When this occurs the comparator actuates a control unit 20 to stop further adjustment of the attenuator. Phase 2 then commences, and with switches 9 and 10 in their lower positions the input to the attenuator 3 becomes U 2  -U 3  and hence the output of the amplifier 15 becomes k(U 2 -U 3 ). This is applied to one terminal of the device 19 together with the output U 1  from transducer 1 to the other terminal. Thus the potential across the device 19 is U 1  -k(U 2 -U 3 ), but since k has been adjusted so that kU 2 =U 1 , the potential across device 19 reduces to U 3  U 1  /U 2 .
