Title: Improvements relating to automatic headlamp dimming apparatus
IPC: B60Q1/14
Filed: 1957-11-19
Abstract: 816,668. Automatic headlamp dimming apparatus. GENERAL MOTORS CORPORATION. Nov. 19, 1957 [Dec. 5, 1956], No. 36010/57. Class 40 (3). Vehicle headlight dimming apparatus which is operated by the lights of an approaching vehicle, comprises a photo-cell 80, valve T-1 and transistor A and B amplifiers and relays 52 and 18 which switch the headlights from high to low intensity when the light incident on the cell reaches a predetermined value. The headlamps 2 and 4 each contain two filaments, high beam 10 and 12 and low beam 6 and 8. The heavy duty relay 18 controls the power circuit to each filament and is itself controlled by the relay 52 when the switch 34 is in the position shown. With no incident light the high resistance of cell 80 in conjunction with resistance 86 maintains the grid of the second part of valve T-1 at earth potential. The valve is cut off by the positive cathode bias applied via the potentiometer 130, hence no base or collector current flows in the transistor A. The very small voltage drop across resistor 122 produces a high base and collector current in transistor B which operates the relay 52 and hence the relay 18, switching the headlights to high beam. When the light incident on the cell increases to a level which allows the valve to conduct the process is reversed and the headlights switched to the dim position. At the same time the bias on the valve is decreased by disconnecting R64 from the power supply, this increases the sensitivity of the amplifier and prevents a change back to high beam when the approaching vehicle dims its lights. The lamps can at any time be switched to high beam by operating the foot switch 34. In a further arrangement (Fig. 2, not shown) feedback is used to increase the speed of operation of the system.

Abstract: 1,141,371. Spray-producers. C. D. LISTER. 3 Aug., 1967 [12 Aug., 1966], No. 36172/66. Heading B2F. In a device for lubricating a moving chain 11, air is fed intermittently to a spray head 18 in which lubricant is entrained in the air as the air expands after passing through a Venturi 55. Air is fed to a regulating valve 13 through a tube 14 and thence to a chamber of a capacity adapted to be varied by a piston 27. A valve 44 is biased by a spring 48 to close an air passage 39, the valve being opened by a lever 17 operated by a roller 53 coacting with links on the chain 11. In operation, the pressure of the air in the chamber builds up until the valve 44 is opened, when a pulse of air entrains sufficient lubricant to lubricate one link of the chain 11. The rate of flow of the air is regulated by the valve 13 to a valve insufficient to entrain lubricant continuously if the valve 44 remains open. A regulator valve 58 controls the flow of lubricant. The lubricant supply pipe 22 is provided at its lower end with a non-return ball valve (23), Fig. 1 (not shown), and is immersed in a lubricant container (21).
