Filed: 1969-04-21
Abstract: 1,209,579. Stud welding circuits. WARREN FASTENER CORP. 21 April, 1969 [22 April, 1968], No. 20155/69. Heading H2H. A control circuit for stud welding apparatus includes a number of energy storage devices which can be discharged simultaneously or sequentially through the stud and workpiece so as to increase the intensity and/or the duraton of the welding current. In the circuit shown, capacitors Cl, C2 are charged through a transformer 20 to voltages which are limited by a Zener diode 98. A welding operation is controlled by a sequence timer 80 which first cuts off the charging circuit by means of a thyristor 92. Next, a triac 72 is gated to supply pilot arc current from a secondary winding 28 to the stud 36 and workpiece 38 which are simultaneously drawn apart by the operation of a stud lift coil 48. A pilot arc is thus formed, and now the timer 80 supplies a signal to gate a thyristor 108 so that the first capacitor C1 discharges through the arc providing current of welding intensity. The same signal actuates an adjustable delay circuit 140 so that a second thyristor is subsequently fired and capacitor C2 discharges through a parallel circuit into the arc. The setting of the delay circuit thus controls the intensity and duration of the arc current. The lift coil 48 is now de-energized and the stud is forced against the workpiece to complete the weld. A manual switch 125 may be held open so that the stud is maintained in contact with the workpiece throughout.

Filed: 1974-05-08
Abstract: 1474764 Matrix displays INTERNATIONAL BUSINESS MACHINES CORP 8 May 1974 [1 June 1973] 20266/74 Heading G5C A display system comprises a gas discharge panel with crossed conductor arrays and means for applying sustain signals and a write pulse of such an amplitude that its trailing edge can cause erasure; the write and sustain signals being arranged to produce a transitional waveform that is substantially continuous from the write signal to the sustain voltage level of the opposite polarity over an interval that is short enough to prevent a cell being erased as the result of any ionization associated with the trailing edge of said write signal. Sustain pulses are produced on the horizontal and vertical conductors 14, 17 by signals 2A, 2C applied to transistors 43, 47. These generate pulses which are applied to transistors 38, 41 producing pulses 2B, 2D on lines 24, 34 connected to the conductors. Prior to write and erase operations all the conductors are grounded by grounding transistors 43, 47 and applying a pulse 2F to turn transistor 65 on. During the period signals are applied to turn selected transistors 19, 20, 28, 29 off. Write pulses 2G, 2H are applied to transistors 49, 50. Pulse 2G turns transistor 49 on and raises line 24 to reference potential to which is added the voltage across winding 54. The pulses produce potentials 2I, 2J on lines 25, 33 which are applied to corresponding conductors since transistors 19, 20, 28, 29 are already off. The write signal comprises a positive ionization pulse immediately followed by a negative going sustain pulse. In another embodiment a group of horizontal conductors at the bottom of the panel are not visible and form a store for a code word corresponding to data written in the visible part of the panel. The code is read by applying write pulses to this lower part of the panel. In cells with a stored charge a relatively low current is produced.
