Abstract: 1,222,814. Road vehicle lighting systems. JOSEPH LUCAS (INDUSTRIES) Ltd. 18 June, 1968 [7 July, 1967], No. 31448/67. Heading H2H. [Also in Division G4] A lighting system, particularly for tractortrailer vehicles, comprises two lamps connected across a battery, and a relay which controls the connection of the junction between the lamps to an intermediate terminal of the battery. The system shown includes sidelamps 11-14, stoplamps 15, 16, and flashers 17, 18, all of which are rated at 12 volts. The sidelamps are connected in pairs between an earth terminal 21a and a second terminal 22a connected to a 24 volt battery by way of a switch (not shown), and the mid-points of each pair of lamps is connected to a 12-volt centre-tapping 33 on the battery through a normally open relay switch 34. Closing the sidelamp switch energizes a coil 35 which closes the switch 34, but in normal conditions no current flows to the terminal 33. However, if one of the lamps 11-14 fails, the other lamp of that pair will stay lit since current can flow through the contact 34. This current flow may actuate a warning device indicating lamp failure. Stoplamps 15, 16 are similarly operated and are connected through a relay 36 to the terminal 33. Flashers 17 and 18 are energized from terminals 24a, 25a and are connected in series with resistors 31, 32 to reduce the applied voltage to 12 volts. The system described is on a trailer vehicle and has a second set of terminals 20a-20c, 22-25 which can be used if the associated tractor vehicle has only a 12 volt supply.

Filed: 1976-07-30
Abstract: 1509973 Centre spindle BSR Ltd 30 July 1976 [30 July 1975] 31840/75 Heading G5R In a record changer centre spindle including three record support arms 32 and three record retaining fingers 50, the arms are not withdrawn to release the lowermost record until the remaining records are held by the retaining fingers. Control rod 13 is slidable within the spindle casing 11 and at its upper end is coupled by spring 25 to cam element 21 which acts on the retaining fingers 50. Slidable on the middle part of the rod 13 is a member 30 carrying the support arms 32 which are biased outwards by blade springs 33. The springs are formed with apertures 36 which embrace a disc like element 37 attached to the control rod and thus limit movement of the member 30 relative to the rod. A further abutment 38 on the rod forms a stop for a spring 39 which at its other end abuts a shoulder (not shown) at the end of a sleeve 40. The opposite side of this shoulder abuts a main return spring 41 for the spindle mechanism. Normally spring 41 forces the sleeve 40 against the bottom of blade springs 35 to push the member 30 upwards against a stop (not shown) and spring 39 pushes the control rod upwards so that abutment 37 is against the upper end of the blade spring apertures 36. The spindle is operated by pulling rod 13 downwards whereby surface 22 of cam element 21 moves retaining fingers 50 outwards to engage below and support the records other than the lowermost, the further downward movement of the rod being accommodated in the cam element by compression of spring 25. During this initial downward movement of the rod the member 30 is unaffected as the abutment 37 moves downward in the apertures 36. When the abutment engages the lower edge of the apertures the member 30 is drawn downwards thereby retracting the support arms so that the lowermost record drops on to the turntable. During release of the last record downward movement of cam element 21 is not opposed by fingers 50 engaging a record and this reduction in the amount of force required to draw down the rod is detected to indicator last record release.
