Patent GB-408310-A (GB)
Title: Improvement in clutch control mechanism for an automobile
IPC: B60K23/02
Filed: 1932-10-04
Abstract: 408,310. Controlling motor vehicles. BENDIX AVIATION CO., 105, West Adams Street, Chicago, U.S.A. Oct. 4, 1932, No. 27535. Convention date, Oct. 5, 1931. [Class 79 (v).] In a vehicle having inter-connected throttle, clutch and brake mechanism a clutch servomotor is energized to disengage the clutch if the accelerator pedal is released and the brake pedal is not operated, but on the operation of the brake pedal the clutch is first re-engaged, to allow the engine to be used as a brake, and on further operation of the brake pedal the clutch servo is controlled by a governor which re-energizes the servo to disengage the clutch when the vehicle speed falls to a pre-determined low limit. In the construction shown in Figs. 3-5, the clutch mechanism (not shown) is operated by a servomotor 22 adapted to be connected, by a pipe 24 and a valve 26 controlled by the accelerator pedal 14, either to the induction pipe 10 to disengage the clutch when the accelerator pedal is released or to the atmosphere to re-engage the clutch when the accelerator pedal is depressed. The brake pedal B, which may be loosely mounted on the clutch-operating shaft C, is connected by a link 78 to a valve 68 and by a link 76 and lostmotion connection 92 to a valve 70. When the brake pedal is in the released position shown the valve 68 connects the servomotor 22 to the pipe 24 and the valve 26 so that the clutch is disengaged if the accelerator pedal is released. If now the brake pedal is depressed the valve 68 is raised and the servomotor is put in communication with the atmosphere via valve 68, pipe 64 and valve 70, so that the clutch is re-engaged during braking. On further depression of the brake pedal the lost-motion at 92 is taken up and the valve 70 is raised, thereby connecting pipe 64 to a bye-pass pipe 641 having a governor-controlled valve 80 and connected at 66 to the pipe 24. The valve 80, Fig. 5, comprises a spring-loaded piston 84 controlled by fluid pressure in a pipe 88 leading from a pump (not shown) operated by the vehicle driving shaft, so that under normal running conditions the piston closes the pipe 641, but as soon as the speed drops to a predetermined minimum the fluid pressure in pipe 88 drops sufficiently to allow the piston 84 to open the pipe 64<1> and thus connect the servomotor 22 to the valve 26 and the induction pipe 10 so that the clutch is disengaged before the vehicle stops. The governor valve 80 may be controlled by a solenoid energized or deenergized in accordance with the speed of the driving shaft.

Abstract: 639,272. Luminescent screens. GENERAL ELECTRIC CO., Ltd. Oct. 14, 1947, No. 27581. [Class 39 (i)] A luminescent screen of long afterglow with exponential decay which is excited by long-wave ultra-violet or visible radiation from a cathoderay tube comprises solidified partially dehydrated boric acid containing as an activator up to 1 per cent by weight of an organic substance which will not decompose appreciably during manufacture of the screen material. Boric acid is mixed with an aqueous solution of the organic substance, e.g. fluorescein or its compounds, uranine, phenol phthalein, 2- naphthylamine-6: 8-disulphonic acid, orthoaminophthalic cyclic hydrazide hydrochloride, naphthalic anhydride, quinine acid sulphate, pyrogallol or sodium salicylate. The preferred amount of activator is .0003 per cent by weight, good results being obtained with .001-.1 per cent uranine. The mixture is stirred whilst heating and when the melt is one-third solid is poured on to a non-adhering surface, e.g. mercury, which can be warmed to prevent too rapid cooling. The material is moulded in plates #-“ inch thick and protected by a waterproof lacquer. Alternatively the melt is poured between two thin sheets of metal foil, e.g. Cu or Ni, enclosed between metal plates heated to 160‹ C. When cold the foil is stripped off. Small plates may be cemented together to form a larger graticule framework. The melt may be cast direct on to a preheated sheet of transparent material of expansion coefficient similar to boric acid, e.g. a glass screen of a cathode-ray tube.

Abstract: 1,002,840. Windscreen wiper. K. KIRCHNER. July 12, 1963 [July 31, 1962], No. 27664/63. Heading A4F. [Also in Division F2] A windscreen wiper has means for changing the drive of the wiper from/to continuous to/from intermittent wiping. The wiper shaft 8 engages the bore of a cylindrical projection 5 on the wiper drive 4 and levers 9 and 10 of different thickness and under spring pressure are eccentrically mounted adjacent the bore. A pin 12 fixed to the drive 4 engages slots in a gear-wheel 14 having a disc 15 mounted thereon and as the wheel rotates the disc prevents the thicker lever 10 from swinging out beyond the periphery of the cylindrical projection 5 except when the position of the wheel is such that the lever 10 is adjacent a recess 16 in the disc when it can then spring out. On counter clockwise rotation of the wiper drive the thinner lever 9 engages the driver 11 of the wiper shaft to bring about continuous wiping, but on clockwise rotation the thicker lever is kept in a neutral position by the disc 15 except in the one above-mentioned position when it can spring out and engage the driver 11 of the wiper shaft to cause intermittent wiping. The direction of rotation of the wiper drive can be changed by means of a switch.

Abstract: 1,044,006. Pulse generating circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. July 18, 1963 [July 19, 1962], No. 27844/62. Heading H3P. [Also in Division G4] In a pulse generating circuit for use in measuring the tracking properties of an electrical insulator 6, Fig. 1, by applying highvoltage pulses to an electrode pair 4, 5 until a conductive track becomes established on the surface of the insulator, a delay line L 1 , C 1  is charged from a 3 kv. A.C. source until it triggers a controlled spark gap G 2  (as described in Specification 861,740, which is referred to) which then applies 10 kv. from a charged capacitor C 3  across the electrodes 4, 5, thereby establishing an arc between them, and the arc is maintained by the energy in the delay line until it is discharged. Once the arc between electrodes 4, 5 breaks the delay line begins to charge again and the cycle is repeated. When a conductive path is established between electrodes 4, 5 a capacitor C 2  begins to charge and eventually establishes a spark at a gap G 1  which, via a relay contact NC, removes the 3 kv. source.
