Patent GB-617893-A (GB)
Abstract: 617,893. Battery lamps. CONCORDIA ELECTRIC SAFETY LAMP CO., Ltd., and LUCAS, H. Jan. 31, 1946, No. 3186. [Classes 39 (ii), 75 (ii) and 75 (iv)] [Also in Group XXXV] A battery lamp has switch means enclosed in the lamp housing controlled by the rotation of the lens ring and reflector. The reflector 4 Fig. 3 (Comp.), is attached to a lens ring 2 and to a bulb holder 12 on which are mounted spring contacts, such as 9a, 9b these contacts being held between co-axial bushes 11a, 11b or being inserted in a plastic moulding in which the reflector 4 may also be inserted or with which the reflector, if plastic, may be integral. The reflector 4 carries a spring 7 having a metal ball 24 adapted to rotate when the lens ring 2 is rotated so as to occupy one of the positions 22a, b, c or d, Fig. 2 (Comp.) in a strip 22 which is electrically connected to terminal 8b. In the position shown, the contact 9b engages a contact 8a and as the rear end of the contact 9b is bent downwardly to engage the bulb 5, Fig. 3 (Comp.) current passes to one filament of the bulb, which may be of the twin filament type or two or more single or multifilament bulbs may be used. When the ring is rotated so that the ball enters the position 22b, the contact 8a is not engaged and the lamp remains unlighted. Further rotation brings the ball into the position 22c where the contact 9a engages the contact 8a so that a second filament is energized and the lamp is lit. A stop pin 23 may be provided in the fourth hole 22d so that the ball may not enter this position until the pin 23 has been withdrawn, as by a magnetic force. In this fourth position, contacts 13a, 13b engage the contacts 8a, 8b and since the rear ends of the contacts 13a, 13b are bent upwardly to engage pins 10, Fig. 3, to which a source of charging current is connected, current is supplied to charge the battery. A stop 21 may be adapted to engage the pin 23 and prevent rotation of the switch beyond the hole 22a, this pin 23, therefore, preventing access to the current-carrying parts of the lamp and allowing the lamp to be opened only when the magnetic force is applied. According to the Provisional Specification the switch may comprise fixed contacts w<1>, w<2>, Fig. 1 . (Prov.) and a rotatable disc x<1> on which are mounted lamp contacts l, m, r and charging contacts x, y. Rotation may be limited by a pin p engaging in a slot z, arranged so that when the pin is at one end of the slot the contacts l, m are put upon the contacts w<1>, w<2> and current is supplied to the left hand filament, while if the pin is at the other end, the contacts m, r are put upon the contacts w<1>, w<2> and current is supplied to the right hand filament. The battery may be charged by applying a magnetic force to withdraw the pin p from the slot z and allow the contacts x, y to be brought upon the contacts w<1>, w<2> to supply a charging current through the battery.

Abstract: 735,260. Stereophonic systems. WARNER BROS. PICTURES, Inc. June 23, 1953 [April 6, 1953], No. 17351/53. Drawings to Specification. Class 40 (4). A stereophonic system for a cinema comprises left, centre and right-hand loudspeakers situated near 'the stage and fed from appropriate left, centre and right sound tracks and a series of loud-speakers in the auditorium, e.g. along the back and side walls, fed with selected background music and effects.

Title: A smoke signalling device to be launched from a submerged submarine
IPC: F42C15/32
Filed: 1978-12-28
Abstract: The smoke signalling device is operated by the hydrostatic pressure of the water as the device travels from the submarine to the water surface. A system of pistons 3, 19, 23; cylinders 2, 16, 24 and springs 21 and 22 operate so that the high pressure prevailing on launching of the device cooks the activating mechanism, and when the pressure drops as the device nears the surface, one of the pistons 23 is drawn back against the pressure of spring 22 until the joint 14 separates whereupon the piston 23 becomes free and is shot forward by the spring 22. The spring strikes a percussion cap 26 which ignites smoke producing material 30. Smoke is produced, and when the pressure in chamber 31 rises to a certain level, a valve 35 opens to allow the smoke to issue. <IMAGE>

Title: Interlocking lid fastenings
IPC: D06F49/00
Filed: 1979-06-20
Abstract: A lid interlock for Spin Dryers and similar machines, comprises a circular plate on which two centrifugal counterweights are mounted. On the underside is a disc which has cam slots connected to the weights and pins slide in these slots to raise and lower the disc. The disc has friction pads attached to the underside which make contact with a static plate to provide a braking action. When the unit is rotated the friction disc remains stationary for a brief moment and opens the weights. There are three holes into which a selector pin whose movement controls the door fastening bolt, engages. One is in the centre boss of the circular plate and one in each of the weights. When the unit is stationary these holes are coincidental and the selector pin will enter them. When rotation movement begins the weights move outwardly and the hole alignment is no longer coincidental, therefore the selector pin cannot be engaged until the rotation has stopped when the lid interlock linkage will again be operational.

Title: Vehicle load sensing arrangement
IPC: B60T8/18
Filed: 1980-01-10
Abstract: A vehicle load sensing arrangement comprises an input arrangement (14,15) to which is applied the force of a road spring (13), and a control valve (1) which may, for example, be a brake pressure reducing valve, having a movable valve member (5). A control spring (24) acts in opposition to the road spring (13) and together with a force-dividing arrangement (19,20) serves to divide the road spring force so that only a proportion of the road spring force is applied to the valve member (5) the remainder being applied to the sprung part (12) of the vehicle. To reduce the load and size of the control spring (24), and to thereby reduce the required installation space, the control spring is arranged between the valve member (5) and the force-reduction arrangement (19,20) and acts against the force transmitted by the force-reduction arrangement, so that the effective force acting on the valve member (5) is the difference between the proportion of the road spring force transmitted by the force-reduction arrangement and the force of the control spring (24).   <IMAGE>
