Title: Improvements in or relating to circuit arrangements including a relay
IPC: H01H47/22
Filed: 1960-11-09
Abstract: 963,588. Binary counting relay circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. Nov. 9, 1960 [Nov. 12, 1959], No. 38497/60. Heading H2H. A binary pulse counting circuit comprises a polarized bi-stable relay whose coil W 1  is serially connected to a capacitor C, which, when contacts i and ia are open is charged to a potential - E. Closure of contacts i discharge the capacitor C through W 1  closing contacts 1a On the second opening of contacts i capacitor C is charged positively, and then discharged on the second closure of contacts i, thus opening contacts 1a and closing 1b. Meanwhile opening contacts 1b charges a capacitor C<SP>1</SP> to a potential +2E and when 1b is subsequently closed, the capacitor is discharged to a potential +E through a coil W 2  of a second bi-stable relay, closing contacts 2a. The second opening of contacts 1b discharges capacitor C<SP>1</SP> to zero, and the second closure of 1b recharges C<SP>1</SP> to +E, thus closing 2b and opening 2a which increases the capacitor C<SP>1</SP> charge to 2E. Contacts 2b may be connected to a further counting circuit. The contacts i, 1 and 2 operate in the ratio 1, 2, 4. R 5 , R 6 , R 5 <SP>1</SP> and R 6 <SP>1</SP> are current limiting resistors.

Title: Device for delivering a firing voltage for semiconductor switches

Filed: 1971-08-31
Abstract: 1361677 Triggering circuits for controlled rectifiers HOLZER PATENT AG 31 Aug 1971 [17 Sept 1970] 40598/71 Heading H2F A circuit for producing a train of trigger pulses in synchronism with an A.C. supply (e.g. for triggering a triac 3) at a phase relative to the A.C. supply, adjustable over substantially a full cycle in dependence on an input signal, has means for producing an additional trigger pulse after any trigger pulse which is produced at more than 180 degrees before the end of a cycle of the A.C. supply, the additional pulse being timed to coincide with the passage through zero of the A.C. supply voltage following that pulse. The triac 3 can thus provide cycles of current the duration of which may be adjustable from a full wave to a small part of a half wave. Alternatively, the triac 3 may be replaced by a rectifying arrangement. As described, each positive half cycle of the A.C. supply is limited by a Zener diode 6 to provide a trapezoidal waveform which is rectified at 7 and smoothed at 8 to form a D.C. supply used to charge capacitor 19 via resistor 18 so as to provide the sawtooth wave (Fig. 3d). Transistor 9 of a reciprocallycoupled complementary pair of transistors 9, 10 is turned on at a point in each sawtooth determined by a D.C. control voltage at terminal 2, so as to produce a pulse to trigger the triac 3. The trapezoidal wave (Fig. 3a) is differentiated by capacitors such as 32, to provide positive and negative pulses (Figs. 3e and 3b) at the bases of transistors 26, 17, respectively. The negative pulses turn on transistor 17 which allows diode 25 to discharge capacitor 19 at the end of each positive half-cycle thus terminating each cycle of the sawtooth wave. If transistors 9, 10 have generated a pulse during the negative half-cycle, the positive pulse will turn on transistor 26 so that diode 25 will trigger transistors 9, 10 to generate a further triggering pulse for triac 3 thus ensuring that it is conductive during the whole of the positive half-cycle. Transistors 9, 10 may be replaced by a four-electrode siliconcontrolled switch.

Zinc is recovered from ferrites by leaching the ferrites with a sufficient excess of H 2 SO 4  to obtain, after breaking down the ferrites, an H 2 SO 4  concentration of not less than 180 gms/litre; separating the insoluble compounds from the resulting solution; increasing the volume of the solution with H 2 SO 4  having a concentration of 150-200 gms/litre; oxidizing with MnO 2  any ferrous ions that may exist; and reducing the acidity of the solution until a concentration of H 2 SO 4  of 3-5 gms/litre is obtained, to precipitate the iron present in the form of basic sulphate. The H 2 SO 4  of a concentration of 150-200 gms/litre may be " return acid " regenerated by subsequent zinc sulphate electrolysis.
