Abstract: 1,124,347. Ignition systems. ROBERT BOSCH G.m.b.H. Sept. 17, 1965 [Sept.23, 1964], No.39684/65. Heading F1B. A high tension condenser ignition system for an internal combustion engine comprises a step up charging transformer 10, a breaker contact 29 for periodically interrupting the flow of current through the primary winding of the charging transformer from a source of direct current B in timed relation with rotation of the crank-shaft of the engine, a storage condenser 14, at least one rectifier 13 connecting the storage condenser to the secondary winding of the charging transformer for charging the condenser before each ignition process, an ignition coil 16, an electronic switch 17 for discharging the storage condenser through the primary winding of the ignition coil at the instant of ignition and a control device adapted to fire the electronic switch in timed relation with opening of the breaker contact but lagging therebehind in phase. A protective rectifier 4 may be connected in parallel with the storage condenser in such a direction as to become conductive to prevent the storage condenser from becoming charged in the reverse direction after discharge. A Zener diode 40 is connected to the junction of the breaker contact with one of the two ends of the primary winding so that should the condenser fail to discharge the voltage to which the storage condenser is charged is limited to a value below that of the self firing voltage of the electronic switch. In place of the rectifier 41 a safety rectifier 42 may be connected in parallel with the control path of the electronic switch in such a direction as to prevent a reverse polarity being applied to the path. As shown the electronic switch is a cold cathode thyratron. The control device comprises a control transformer 20 and a control breaker contact 23. Several Zener diodes or rectifiers connected together may be used instead of only one Zener diode 40 or only one rectifier 41, 42 or 43. Use of thyristors is referred to.

Abstract: 1,225,464. Transistor pulse circuits. INTERNATIONAL BUSINESS MACHINES CORP. 20 Oct., 1969 [18 Nov., 1968], No. 51351/69. Heading H3T. A pulse transfer system uses bidirectional amplifiers each of which has an input, an output and a common terminal wherein an input signal on the input terminal appears at the common terminal and an input signal on the common terminal appears at the output terminal; and one or more such amplifiers 2, (4, 6, Fig. 1, not shown) have the output terminal or terminals connected in common to all the input terminals of another group of such amplifiers 16, 18 (20) and the output terminals of the other group are connected in common to the input or inputs of the said one or more amplifiers 2 (4, 6). Each amplifier, such as 2, consists of an emitter-coupled pair T1, T2 with a constant current source T5, the common terminal A1 (or B1 in 16; B2 in 18) being connected to T1 base and the output terminal at 29 to T2 collector. A level-shifting circuit 10 using transistors T8, T9, T10 drives, via lead 39, the input terminals of the amplifiers 16, 18, whose output terminals are connected via line 37 to another level shifting circuit 12 (T11, T12, T13). This is connected via line 23 to the input terminal of amplifier 2, which input drives the bases of T3, T7 in respective emittercoupled pairs T3, T4, and T6, T7. The collector of T4 thus produces an output on the common lead 25, but the first emitter-coupled pair T1, T2 is insensitive to the outputs of T4, T7 which are applied respectively to the bases of T1, T2, in common mode. A threshold circuit 14 using T14 produces an output at 5 (line 5, Fig. 3, not shown) if signals appear at two or more of the terminals B1, B2 simultaneously; the outputs of amplifiers 16, 18 are commoned by having a common collector resistor 72, and if two transistors T15, T25 connected thereto conduct simultaneously, the voltage across R72 exceeds the threshold of T14. Pulses pass both ways through the system, and may do this simultaneously in which case two signals may be superimposed at a common terminal (for example at A1 between timer S10, S11, Fig. 3, not shown).

Abstract: 1,228,026. Spinning yarns. IMPERIAL CHEMICAL INDUSTRIES Ltd. 9 April, 1969 [16 April, 1968], No. 17890/68. Headings D1F and D1W. A simulated staple fibre yarn the fibres of which are of various lengths is produced by dividing a non-woven web of randomly-laid continuous filaments into strips and twisting the fibres of the strips together to form the yarn. The web may be formed by withdrawing synthetic polymer e.g. polyhexamethylene adipamide and/or polyipsilon caprolactam, filaments from packages or a melt spinning head and laying them by nip rolls or air ejection in random or predominantly random manner onto a foraminous conveyor belt: it may be stabilised, by steaming, before stitching as by use of stationary, rotary, or vibratory knives, jets of hot air or steam, or hot wires. The strip may be twisted on a ring-spinning frame or one or more e.g. five, strips may be converged into feed-stock supplied to a breakspinning device such as described in Specification 1,031,150. Drawing and/or further drawing of filaments or yarn may be effected during and/or after twisting e.g. to produce a desired final denier. The fibres may be bonded together, before or after forming into yarn, by mechanical treatment e.g. needle punching, or adhesive bonding eg. impregnating the web, strip or yarn with a non-fibrous agent or by incorporation of binder filaments such as composite (core-and-sheath) filaments containing a potentially adhesive or heat activatable component in the web. The filaments may be crimped or have a crimp potential which can be developed at any stage.

Abstract: 1,239,716. Control of D.C. motors. WESTINGHOUSE ELECTRIC CORP. 11 March, 1970 [28 March, 1969], No. 11661/70. Heading H2J. In the forward-run position of a selector switch S1-S5, the armature A of a reversible motor M is supplied from a bridge rectifier PS, comprising phase-controlled thyristors SCR1, SCR2, through a series thyristor SCR3. A freewheeling diode DF ensures correct commutation of the thyristors SCR1, SCR2. To brake the motor, the selector switch is adjusted to shortcircuit the output of a gate pulse source GS whereby the thyristors SCR1, SCR2 are blocked. The gate and cathode of the thyristor SCR3 are short-circuited so that this thyristor is turnedoff A network BSC is connected across the armature A, a thyristor SCR4 being turned-on to complete a circuit through braking-resistor RB and relay Y. Contacts X1, X2, are actuated to ensure that the thyristors SCR3, SCR1, SCR2, are kept turned-off until the motor has stopped. If the selector switch is adjusted to the reverse-run position during a braking operation, the thyristor SCR4 stops conducting and the contacts X1, X2 return to their open state when the armature current reaches zero. The armature current is then reversed, the thyristors SCR1, SCR2, SCR3 being turned-on. The thyristor SCR4 is turned-off while capacitor Cl is charged to prevent rising voltages caused by the turning-on of thyristors SCR1, SCR2, from being impressed across the thyristor SCR4, which could be damaging thereto. If the A.C. source is disconnected from rectifier bridge PS and the selector switch moved to the reverse position which the motor is operating forwardly, and the A.C. source is then re-connected, the capacitor C1 supplies sufficient voltage to fire the rectifier SCR4 and to energize relay Y. The motor is thus braked to a standstill before its armature is re-energized.
