Abstract: 991,304. Welding by pressure. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Dec. 11, 1962 [Dec. 14, 1961], No. 46734/62. Heading B3R. In a stud welding device in which a solenoidoperated switch is connected in the welding supply circuit to be energized by a switching on contact and de-energized if the voltage across the parts to be welded falls below a predetermined low value the welding voltage or a voltage derived therefrom is supplied to two parallel branches, one branch comprising the energizing coil of an auxiliary relay and the other branch comprising the series arrangement of the coil of the switch, the switching on contact and a contact of the relay, the latter contact being connected by a holding contact of the switch. A low voltage supply device 2, Fig. 1, is connected to a stud welding gun 5 and to the work 6 via a switch 3 operated by a solenoid coil 4 connected to the positive side of a rectifier 7 connected across the device 2. The coil is connected via a solenoid switch 9 and starting contact 10 in the gun to the negative side of the rectifier. In operation the rectifier 7 energizes the coil 8 of the switch 9 to close the switch. Operation of switch 10 energizes coil 4 to close switch 3 and apply welding voltage to the workpieces. A holding contact 11 is also closed and the switch 9 opens since the coil 8 is shortcircuited by switch 10. When the weld is formed the voltage across the workpieces is so low that rectifier 7 is short-circuited and coil 4 is de-energized to open switch 3. In a modification the coil 4 is supplied from a rectifier 23, Fig. 2, connected across the device 2 and in series with the switch 9 of the coil 8 and a contact 22 of a further solenoid switch which is provided in a parallel circuit across the device 2. The further solenoid switch comprises a coil 20 supplied from rectifier 7, the normally closed switch 22 and a normally open switch 21. In operation the coil 20 is energized from rectifier 7 to close switch 21 and open switch 22, thus energizing relay 8 to close switch 9. On closing switch 10 the relay 20 is short-circuited to open its switch 21 and close its switch 22. The condenser 13 across coil 8 retains contact 9 closed while coil 4 is energized to close switches 3 and 11. After welding is completed coil 4 is short-circuited and switch 3 opens.

A system, for detecting binary signals of the kind in which a clock interval includes a clock pulse and a data pulse when the signal represents a first binary value and includes only a clock pulse when the signal represents a second binary value; includes an input terminal 14 for the binary signals connected to a clock pulse detector 13 producing, at a first output terminal f, an output clock pulse of predetermined duration in response to an input clock pulse; and a reset input 16 to the clock pulse detector, connected to a second output terminal d, whereby the output clock pulse can be terminated prematurely. A timing circuit-data detector 11, depicted in detail in Fig. 3 (not shown) is set by each input pulse b, whether clock or data, and produces an output pulse d only in the absence of a data pulse between two clock pulses, this being the only condition in which a capacitor in circuit 11 has enough time for its charge to decay sufficiently to switch a transistor. The input signal is also led, via a delay circuit 12, for example a capacitor or a monostable multivibrator, to the clock pulse detector 13, which detector comprises a monostable multivibrator which is set by each clock pulse and which then ignores the following data pulse, if present, whilst decaying. The decay periods of circuits 11, 13 and the delay of circuit 12 are chosen to allow the system to operate when the clock and data pulses are slightly displaced in time. The output data pulse is used to resynchronize the output clock pulse by resetting the clock pulse detector before the end of its decay period.

Filed: 1974-11-04
Abstract: 1485993 Ignition system SIEMENS AG 4 Nov 1974 [5 Nov 1973] 47674/74 Heading F1B In an ignition system including an ingnition coil 10c in series with a switching transistor 10f, the control system includes a contact breaker 13, e.g. mechanical, electromagnetic or electro-luminescent, and is effective to render the 'on' time of the switching transistor, and hence the time of energizing the ignition coil, substantially independent of engine speed. As shown, immediately after contact 13 opens, a logic evaluator 12 passes a current through contact units A, C to connect an integrator 11 to a fixed voltage source 5 and to negatively bias the inverting input of an operational amplifier forming part of a voltage comparator 7. The integrator 11 therefore begins to integrate the negative fixed voltage U5, and the voltage comparator 7 produces a constant voltage output fed to the power stage 10 to cause transistor 10b to conduct and hence to turn transistor 10f 'off'. When contact 13 closes, logic evaluator 12 cuts-off the current from control units A and C, connecting integrator 11 to a fixed voltage source 6, and disconnecting voltage source 9 from the comparator 7, so that voltage source 8 becomes effective. The integrator 11 now integrates the positive source U6 in the opposite sense until the integrator output equals that of source 8 when the output from comparator 7 drops to zero switching off transistor 10b, and hence switching 'on' transistor 10f to energize coil 10c for a time until contact 13 again opens, when an ignition spark is produced. A device 16 passes a current through control unit B each time the contact 13 opens, to close a contact b in parallel with the operational amplifier 11a of integrator 11 to reset the integrator. A device 18 ensures that should the contact 13 be closed with the engine idling, the transistor 10b will be switched 'on' to switch transistor 10f 'off' to avoid a continuous power dissipation in the ignition coil. The output voltage of the integrator 11 reaches its saturation value in the engine starting speed range to increase the energy and duration of the ignition spark. The integrator may be a digital counter, and the comparator may be analog or digital.

The period of operation of these contacts may be indeterminate but by means of a pair of impulse converters 9, 10, comprising capacitors and control transistors a pulse of predetermined duration drives the punch 51. A holding circuit connected to an electromagnet 15 ensures that the punching operation is completed before the case-shift key is returned.

Abstract: 1524559 Ignition systems ROBERTSHAW CONTROLS CO 24 Nov 1975 [2 Nov 1974]  48235/75 Heading F1B [Also in Divisions H2 and H3] An ignition system 10 for a combustion chamber 20 supplied with fuel oil by a burner motor (not shown) comprises electrodes 16, 18 connected to a pulse generator circuit 12 consisting of a pulse generator formed by members SCR1, T1, C3, D4 and R6, a trigger circuit formed by members R1, R2, D1, C1 and D2, and a turnoff circuit formed by members C2, D3, R1, R3 and R4, the diode D4 being of the fast recovery type to assist in the reliable turn-off of rectifier SCR1 and so ensure a multiplicity of ignition pulses during each positive half cycle of the AC supply accross members L1, C3, R7 causing operation of the circuit 12. A typical turn-on and turn-off of the rectifier SCR1 is described for the condition when the AC supply passes through zero and begins its positive rise. Figs. 3, 4 and 5 (not shown), this operation being repeated about forty times during each positive half cycle. After turn-on of rectifier SCR1 by the trigger circuit and discharge of capacitor C3, the latter is charged in the opposite direction by the collapsing field of transformer T1, until rectifier SCR1 is turned off by the resultant reverse voltage applied to its anodecathode circuit by capacitor C3 and to its gatecathode circuit by the turn-off circuit. The high voltage pulse produced by the initial collapse of the transformer field is mostly dissipated in the resistor R6 due to the rapid turn-off of the diode D4, thereby relieving the rectifier SCR1 of this surge of energy and assisting in its turn-off by the action of capacitor C3 and the turn-off circuit. The chamber 20 may include a section to blow the discharges between electrodes 16, 18 into the oil spray. The ignition system may alternatively be used with a micro-wave oven.
