Abstract: 1446887 Automatic control buffer couplings MINISTRY OF TRANSPORT 5 Dec 1973 [1 March 1973] 56445/73 Heading B7T In an automatic central buffer coupling carrying service line (e.g. air, electricity) couplings in a housing 3, the buffer coupling includes a feed device for feeding the service line couplings forwardly into the desired position during coupling, the device comprising an actuating lever 9 and a feed lever 1 which are connected by a spring 8 and pivoted about a common pivot 7, and the feed lever 1 being coupled to the service line couplings by engagement of a head 1a at the free end of the lever 1 in a slot 2 in the housing 3 so that in use, on a buffer coupling operation with a similar central buffer countercoupling which actuates the lever 9 and hence via spring 8 the lever 1, the service line couplings are moved forwardly and upwardly by the lever 1. To effect such movement of the service line couplings, a forward surface portion 5 of the head of lever 1 contacts a surface portion 4 of the slot 2 in the housing 3, the surface portions 4 and 5 being mutually shaped so that as the housing is moved forwardly, an upward thrust is also imparted to the housing to ensure correct abutting alignment of the service line couplings with those of the counter.coupling. As shown in Fig. 2, the surface portion 5 is chamfered or bevelled downwardly and the surface portion 4 of the slot is correspondingly oblique. In other forms, either the surface portion 5 is convexly shaped, Fig. 3 (not shown), or the portion 4 is convexly shaped, Fig. 4 (not shown).

Abstract: 1,240,319. Protecting thyristor circuits. SCHALTBAU G.m.b.H. 10 Dec., 1968 [15 Dec., 1967], No. 58654/68. Heading H3T. [Also in Division H2] To protect from overheating a semi-conductor switching element, such as a thyristor or a transistor, which is supplying a load in an ONOFF mode, the switching element has a temperature sensor, such as a thermistor, physically associated therewith, the sensor functioning to modify the mark-space ratio of the switching element operation so as to limit the temperature developed by the element. The switching thyristor may control the current supplied to the motor of a battery driven truck, the thyristor being triggered by a sawtooth voltage from a multivibrator superimposed upon a D.C. bias determined by the operation of the accelerator pedal of the truck. Should the combination of these two voltages cause the thyristor to overheat, the thermistor becomes effective to reduce the sawtooth frequency and hence modify the mark-space ratio of the thyristor operation. An over-riding signal is provided to render the thyristor non-conductive if the mark is greater than a desired time. In other embodiments, the thermistor controls the repetition of the firing pulses to the thyristor.
