Title: Timer for a high speed resistance welding machine
Inventor: ROCKAFELLOW STUART CRAGO
IPC: H03K17/288
Filed: 1958-02-20
Abstract: 833,389. Control systems for resistance welders. ROBOTRON CORPORATION. Feb. 20, 1958, No. 5546/58. Class 38 (4). A timing circuit for a resistance welder times the electrode moving circuit from the time that the welding current is applied in order to reduce the delay between cessation of the welding current and the opening of the electrodes. A thyratron 3 controlling the electrode movement through a relay 6, 8, 9 is controlled by a C.R. circuit 29, 31, 32 charged through a rectifier 26 from a pair of A.C. lines 1, 2 through the primary winding 22 of a transformer 23, which energizes another thyratron 38. A thyratron 21 is controlled by a C.R. circuit 12, 13 charged through a thyratron 11. On closure of a switch 4 thyratron 3 conducts, operating relay 6, 8, 9 which causes closure of the welding electrodes and selfmaintaining contacts 6. A C.R. circuit 14, 15 is now charged through a rectifier 17 and a switch 18 which blocks thyratron 11, causing capacitor 12 to discharge. Subsequently thyratron 21 conducts, energizing transformer 23 which supplies energy to a thyratron 38, conduction of which energizes a further thyratron 57 controlling the welding current. When the negative potential of a C.R. circuit 51, 52 charged from the lines I, 2 through a rectifier 48 overcomes the positive potential of a capacitor 34 the welding current is terminated and similarly when the negative potential of capacitor 52 overcomes the positive potential of discharging capacitor 29 thyratron 3 blocks releasing the welding electrodes which may therefore commence to open. By adjustment of the timing circuits the electrodes may open either in advance or arrear of the termination of the welding current. Release of the relay 6, 8, 9 causes the thyratron 11 to conduct when C.R. circuit 14, 15 has discharged thus extinguishing thyratron 21. When switch 18 is thrown to repeat position and the switch 4 held closed the above cycle will take place continuously.

Title: Electronic sequence switch
IPC: G11B15/14
Filed: 1961-02-16
Abstract: 954,231. Television; thermionic distributers. FERNSEH G.m.b.H. Feb. 16, 1961 [Feb. 17, 1960], No. 5739/61. Headings H4F and H4P. Signals appearing at terminals I, II, III and IV, Fig. 1, are applied in a non-overlapping sequence to a common output terminal 18 by rendering transmissive in turn normally non- conductive gate stages 13-16 by means of switching signals O, Q, P and R, Fig. 2, obtained by combining 500 c/s. square waves M and N with 250 c/s. square waves E, F, K and L, the waves being derived from 1000 c/s. square waves A and B produced by a symmetrical multivibrator 1 with the aid of binary dividers 2, 3, 7 and 8. In accordance with the invention, multivibrator 1 is synchronized by a signal H with the aid of a phase comparitor stage 5 in which a sawtooth signal J derived from signal H by means of circuit 6 is compared with a pulse G derived from 250 c/s. square wave E by means of circuit 4. Circuit 4 is arranged to permit pulse G to be varied in phase with respect to wave E in order that the switching sequence may be established in a desired phaso relationship with signal H. A signal from divider 3 is applied to divider 7 and signal H is applied to divider 8 for the purpose of ensuring that dividers 7 and 8 operate at the correct phase in the sequence. The invention is stated to be particularly applicable to apparatus for reproducing video signals recorded on a magnetic tape in which four transducer heads mounted on a rotating member become operative in sequence to recover the signals. Signal H is derived photo-electrically from the movement of the rotating member. To ensure that the switching operation of gate stages 13-16 takes place during line flyback intervals, a trigger circuit 19 may be included in the connection from multivibrator 1 to divider 8 and controlled by line synchronizing pulses applied at 20 so that the transitions in waves M and N are initiated only when a synchronizing pulse occurs after a transition in wave 3.
