Abstract: 1,231,552. Track switch operating mechanism. PHILIPS' GLOEILAMPENFABRIEKEN N.V. 21 Jan., 1970 [24 Jan., 1969], No. 2977/70. Heading B7N. In a track switch operating arrangement, when each switch tongue has been moved to its required position, the appropriate tongue is resiliently urged against its associated rail. Switch tongues 4, 5 are coupled by bar 6 and connected by an adjusting bar 7 to an operating stretcher bar 8 in switch box 9. An additional lock bar 10 and bars 11, 12 for operating the points position detectors also enter the switch box. The stretcher bar 8 is connected to one arm 14 of a two-armed lever 15 pivotally mounted at 16 and having the free end of its second arm 17 recessed 40 and angled 18, 19 to receive a driving pin 24. The pin is mounted on a reciprocating element 22 coupled by nut 23 to drive shaft 20. The arm 17 also supports at pivot 27 a flat plate 28 with uptur ned portions 29, 30 on which cup springs 33, 34 are mounted by nuts and bolts 31, 32. One of the bolt heads can engage an abutment surface 36 or 37 on a support 35 secured to the lever 15. The free end of the plate 28 is formed similarly to the free end of arm 17 of the two-armed lever except that the surfaces 38, 39 enclose a smaller angle than the surfaces 18, 19. In use shaft 20 is rotated by a motor (not shown) and moves drive pin 24 into engagement with the recess 40 at the end of the lever and thus moves the switch tongues to the required positions. The final movement of the pin rotates plate 28 about its pivot, whereby a further resilient force is applied via the springs and the support 35 to move the appropriate tongue into contact with its associated rail.

Abstract: 1,251,665. Collapsible steering columns. ARA Inc. 2 Oct., 1968 [2 Oct., 1967], No. 46690/68. Heading B7H. An energy absorbing steering mechanism for a vehicle comprises telescopically interengaging upper and lower column portions, 14c, 18c, cycling and energy absorbing means 74 associated with the column portions for absorbing energy by cyclical plastic deformation on axial collapse of the column and means 302 for absorbing energy in a non-axial direction. The steering column encloses and supports a steering shaft. The energy absorbing means comprises a number of circumferential circular section arcuate or toroidal elements or a helical element 74 which are or is " rolled " between the inner and outer column portions on their telescoping. The helical element may be divided into two sections by a spacer 206. Individual parts of each element, which may be formed from aluminium or beryllium copper wire, are cyclically subjected to tension and compression loads as the element " rolls " about its longitudinal central axis and is plastically deformed, thereby absorbing energy. To control the rate of energy absorption, the inner portion 12c is tapered. To facilitate collapse and absorb energy when non-axial loads are applied to the steering column, a low friction P.T.F.E. or other bush 302 which engages the inner tube is mounted in the outer tube. An elastomeric member (212) (Fig. 14, not shown) may be mounted between the steering wheel and column.

Abstract: 1,251,980. Battery-charging circuits. BARDIC SYSTEMS Ltd. 30 Oct., 1969 [31 Oct., 1968], No. 51758/68. Heading H2H. An auxiliary battery is charged in parallel with a main battery by an internal combustion engine system. An over-current relay is connected in series with the auxiliary battery so that the latter is disconnected if an excessive current is drawn. In the system shown, an auxiliary battery 10, for example on a trailer or caravan, is connected to a main car battery 12 by way of socket terminals 13, 14, a current relay winding 16, and a normally closed contact 17/1. In normal operation, the batteries are charged in parallel by a generator 27, but operation of the car starter will tend to draw a large current not only from the main battery 12 but also from the auxiliary battery 10. To prevent this, at a current of, say, 8 amps., the relay 16 closes its contact 16/1 and energizes a relay 17 which opens the contact 17/1 and disconnects the battery 10. The contact 16/1 now reopens, but the relay 17 remains energized for a predetermined time, say, a few seconds, owing to the presence of a large capacitor 21. After this time, the contact 17/1 recloses and normal charging will continue unless the overload condition still prevails when the disconnection cycle will be immediately repeated. The main battery terminals may also be connected through a rectifier 24 to an external A.C. supply 25 which can be used to charge the batteries or to supply loads in the caravan or trailer while the car is parked.
