[Also in Division H3] A magnetic amplifier is arranged to produce pulses of opposite polarity to respectively switch on and off a controlled rectifier. The magnetic amplifier shown comprises two windings 7, 8 on saturable cores 5, 6 and connected through rectifiers 14, 15 to load 17 so that the current from one winding is normally equal and opposite to that of the other and no current flows in the load. The bias resistor 13 is selected so that saturation normally occurs at the 90-degree phase point. However, if a control current is supplied to windings 8 one core will saturate earlier and one later so that pulses will be produced across the load, the polarity depending upon the sense of the control current. The pulses are applied to a gate controlled rectifier 2 arranged so that positive pulses will turn it on whereby load 24 is energized and negative pulse will turn it off. Bias for the rectifier is provided by circuit 25, 26, R, C, and a capacitor 37 by-passes unwanted high frequency currents. The rectifier is isolated from supply line interference by a filter LC.

[Also in Division B7] In a vehicle a seat belt system comprises a support, a retractor member movable on the support to extend or retract the belt, has means for urging said member to retract the belt, a seat belt connected to the retractor member, a stop member mounted on the support to prevent or allow belt extension, means biasing the stop member toward the preventive. position, an actuator which when electrically energised will move the stop member to the release position but when deenergised will lock the stop member, and an electrical circuit, including a power source, connected to the actuator to energise or deenergise it according to the condition of motion of the vehicle, a switch in the circuit sewing to lock the system on de-energisation of the vehicle ignition circuit. Two embodiments are disclosed of which one is a rotary reel retractor and the other a linear retractor. The electrical circuit may include devices for detecting vehicle conditions, such as a mercury switch to detect abrupt acceleration or deceleration or skew orientation, or a hydraulic pressure switch combined with the vehicle's braking system. In the linear retractor of Fig. 3, a carriage 42 slides in a channel-shaped housing 24 and is biased by a spring 44 toward the pivoted pulley 48, the seat belt being fastened at the end of the housing remote from the pulley and looped through a retractor bar 52 mounted on the carriage. A locking bar 64, biased by a spring 66, engages abutments 68 on the side of the housing to lock the carriage and hence the belt. The bar however is kept from engagement under normal vehicular conditions by the action of a plunger 72 and an energised solenoid 70, but when the solenoid is de-energised the plunger is released and the bar locks. The solenoid is energised with the ignition system of the vehicle, and a time delay switch may be included to ensure that the solenoid remains de-energised for a predetermined time. Fig. 8 shows a reel type retractor, in which a solenoid and plunger, when energised, prevent a toothed pawl 230 from engaging a toothed reel 222. On de-energisation of the solenoid, the pawl engages the reel, under the action of biasing spring 244, and locks the seat belt system.

Abstract: 1,266,474. Button sewing machines. G. M. PFAFF A.G. 30 July, 1970 [2 Aug., 1969], No. 36864/70. Heading D1G. A machine for sewing on buttons in which a support 23 for a button clamp 55 located below the needle 40 of the machine and a material holding plate 45, 37 on a plate 24 are connected together by gearing 28, 32, 29, 33 in such a way that the plates 23, 24 can be moved together by a cam and can be displaced relative to each other by a second cam. A first cam moves a rod 22 which is fixed to plate 23. Movement of plate 23 carrying the button clamp 55 on arm 17 causes the gear wheel 28 to rotate and thus the gear wheel 31 rotates to move the plate 24 in the same direction and to the same extent as plate 24. When a cam 56 is rotated to move shaft 34 axially the gear wheels 28, 29 move transversely to the plates 23, 24 and cause movement of the plates relative to each other in the longitudinal direction. This movement causes relative movement of the button clamp and the work holder which allows for the production of some blind stitches at the completion of the button sewing to prevent folding of the material.
