Filed: 1939-07-20
Abstract: 532,326. Valve relay circuits. TELEPHONE MANUFACTURING CO., Ltd., and PADDLE, L. H. July 20, 1939, No. 21099. [Class 40 (v)] A differential relay R is operated by D.C. signal impulses applied to the terminals A, B or by A.C. signals applied to transformer 3 and rectified at 4, 5. Valves V1 and V2 are normally non-conductive and conductive respectively. A signal applied to the grid of V1 causes reduction of anode current of V2 which current passes through resistance 15, thus a positive feed-back is given to the grid of V1, and the anode current of V2 builds up very quickly. The decrease of current in relay coil 28 causes an increased voltage across resistance 17 and hence an increased current in the oppositely wound relay coil 29. Reverse action occurs when the signal ceases. Condenser 22 or 22a slightly delays the reverse action of the relay R.

[Also in Division B5] Apparatus for determining the separation of the platens 12, 13 of a press comprises means 32C, 32F for detecting the position of the moving platen 13, and means 20 for detecting the press load in order to compensate for extension of the press frame 15 under load. An hydraulic forging press has its crosshead 14 connected by a cable 24 to a position detector comprising a grooved pulley 23, Fig. 3, around which passes the cable, whose shaft 28 is geared to a toothed sector 27 loaded by a spring or by a pneumatic cylinder 25 whereby the cable is wound on to the pulley as the crosshead ascends. Shaft 28 is coupled through gearing to a coarse magslip transmitter 32C and a fine magslip transmitter 32F which give an output according to the position of the crosshead, and to tacho-generators 36, 37 which give signals dependant upon the speed and direction of the crosshead. The output of magslip 32C, 32F passes through line 45 and zero setting coarse and fine magslips 46C, 46F to a control unit 47. The latter also receives speed-responsive signals along line 38 from the tacho-generators 36, 37 and further signals along line 22 from a pressure transducer 20 connected to the hydraulic supply of the press. Signals corresponding to the upper and lower limits of the crosshead, pre-set by coarse and fine magslips 40C, 40F and 42C, 42F respectively, fitted with indicators, are fed through change-over switch 44 to the control unit 47. The latter gives an output signal along line 50 through change-over switch 51 for controlling hydraulic valves V1, V2, V3. Switches 44, 51, which may be relays or electronic switches, are operated by signals received from the tacho-generator 36, 37. Near the end of the descent of the crosshead the control unit 47 changes over automatically from coarse to fine setting and at the limit of the descent produces a zero error signal which operates a change-over valve V1 to start the upstroke. At the end of the upstroke a rest valve V3 is operated together with a time delay 52 and subsequently a valve V2 produces the next forging stroke. A further cable 24A connected to the opposite side of the crosshead from cable 24, operates a fine magslip 54F to compensate for any tilting of the crosshead. The magslips 32C, 32F and 54F are coupled as described in Specification 968,549.
