Abstract: 1,230,502. Vehicle safety apparatus. AMERICAN SAFETY EQUIPMENT CORP. 23 June, 1969 [28 June, 1968], No. 31497/69. Heading A3V. Vehicle safety apparatus comprises a strap 25 having at its free end a latch 26 for engagement with a floor hook, and being attached at its other end to spring loaded retraction means 27, the means 27 consisting of an arbor 26 rigid with a cylinder 40 and ratchet wheels 43 and extending between walls 32, 33 of a frame 30, the slotted end 37 of the arbor being engaged by a spring 38 for retraction of the strap such that after the strap is protracted and then allowed to partially retract further retraction or protraction is prevented. When the strap is fully wound on the cylinder 40 its bulk causes a sensor 61 to move pawls 60 away from ratchet wheels 43, but when the strap is protracted a spring 59 allows the pawls to move towards the wheels 43 but they are prevented from engaging the ratchet notches by a lock element 56 on a locking disc 53 which frictionally moves from the full line position in Fig. 8 to the broken line position. When the strap is then retracted partially the locking disc 53 retains its full line position and the pawls 60 enter the ratchet notches thus preventing further retraction or protraction. When it is required to store the strap, latch 26 is engaged with a hook 74 of stowing means 28 which hook is then pivoted to operate a switch 27 causing a solenoid to withdraw pawls 60 allowing spring 38 to retract the strap. In a modified embodiment the retraction means may be mounted in the vehicle ahead of the driver and the strap passed round a roller behind the driver. In this embodiment the stowing means in the form a hook is associated with the retraction means and when engaged by the strap latch mechanically withdraws the pawls 60.

Abstract: 1,250,183. Inverters. WESTERN ELECTRIC CO. Inc. 1 Nov., 1968 [1 Nov., 1967], No. 51922/68. Heading H2F. In an inverter, wherein square wave drive signals from a source 16 cause pairs of transistors 12, 13 and 14, 15 to conduct alternately to supply a load 11 with A.C. from a D.C. source 10, the drive signals are shorted by a transistor 27 during commutation period to ensure a definite "dead time " so that one pair is completely turned off before the other pair is turned on. The drive signals are applied to the transistor's bases by respective secondaries 18-2, 18-3, 19-2, 19-3 of drive transformers 18, 19. The drive signal current B (Fig. 2) is monitored by a primary winding 21-1 in series with the primaries 18-1, 19-1 of the drive transformers and with a saturable reactor circuit 20 so that when the drive current changes direction a voltage is induced in secondary 21-2. This voltage is rectified in a bridge 24 and causes a current pulse C to flow through a capacitor 26 to T27 base saturating the transistor which acts as a short-circuit across auxiliary windings 18-4, 19-4 of the drive transformer via rectifier bridges 32, 33. Thereby the drive signals are effectively shorted. A diode 28 allows C26 to discharge between the pulses. Because of phase difference between drive voltage A (Fig. 2) and drive current B, due to the saturable reactor circuit, voltage wave polarity changes distort the current wave as indicated and can cause ringing currents which may undesirably initiate shorting pulses. This is prevented by a blanking signal D which back biases T27 and is produced by a transformer 22 the primary 22-1 of which senses each time the voltage wave polarity changes and induces a voltage in secondary 22-2. This voltage is rectified at 30 and applied across the base and emitter of T27 preventing its conduction.

Abstract: 1,251,942. Circuit breaker tests. SIEMENS A.G. Jan.20, 1970 [Jan. 21, 1969], No. 2816/70. Heading G1U. In a synthetic test circuit for testing a circuit breaker 5 of the type having a parallel switching resistor 18 of low value in which the outputs of a high current source 1 and a high voltage source 9 are applied in succession to the breaker, the resistor 18 is shifted to a position 18<SP>1</SP> in which it ceases to shunt the output from the high voltage source.  When current from the supply source 1 drops to zero after opening auxiliary switch 4 and the circuit breaker 5, a restriking voltage is applied from the current supply source 1 via capacitor 15 to the breaker. In addition, at this time, spark gap 11 is fired so that a high voltage stored in capacitor 10 is applied to the breaker to increase the restriking voltage. In its position 18<SP>1</SP> the resistor is in shunt only with the supply from the current source. Capacitor 6 ensures that the restriking voltage rises at a suitable rate.
