Title: Improvements relating to electric lamps
IPC: H01J61/96
Filed: 1934-12-08
Abstract: 447,428. Supply systems for discharge lamps. SIEMENS ELECTRIC LAMPS & SUPPLIES, Ltd., Caxton House, Tothill Street, Westminster, and LE MERECHAL, W. H., and ALDINGTON, J. N., c/o Siemens Electric Lamps & Supplies, Ltd., Dock Road, Preston, Lancashire. Dec. 8, 1934, No. 35343. Drawings to Specification. [Class 38 (iv)] [See also Group XL] An electric lighting unit comprises a highpressure mercury-vapour lamp and in series therewith a resistance having a positive temperature coefficient, some or all of which resistance is light-emitting, arrangements being made to cut out automatically part of the resistance, which part includes always any light-emitting part, when the voltage across the lamp approaches its working valve. The resistance may be a gas-filled metal filament lamp with a tapped filament part of which may be short-circuited, or a number of lamps, some of which may be switched out. An electromagnetic switch responsive to the voltage of the lamp may be used, but preferably a bimetallic switch is actuated by the heat of the discharge lamp. A mercury-vapour lamp is described which is combined with a tapped tungsten filament, a portion of which is adapted to be short-circuited by a bimetallic switch. The discharge lamp contains mercury and additional quantities of metal such as zinc and cadmium which give the lamp a rising voltage - current characteristic more nearly resembling that of the tungsten filament than does the nearly flat characteristic of a pure unsaturated mercury filling. Voltage fluctuations in the supply mains are thus distributed more evenly between the discharge lamp and the filament. Dimensions and details of electrical performance are given for the lamp described. Specification 431,382, [Group XL], is referred to.

Title: Clutch operating mechanisms for motor vehicles
IPC: F16D48/06
Filed: 1973-07-25
Abstract: 1459419 Clutch control; valves AUTOMOTIVE PRODUCTS Ltd 21 Jan 1974 [22 Jan 1973 25 July 1973] 55641/73 and 35414/73 Headings F2L and F2V A friction clutch on a motor vehicle is disengaged by a slave piston and cylinder 48 supplied with liquid under pressure either from a master cylinder 10 operated by a pedal or from an accumulator 23 through a solenoid 34 operated valve 15, the solenoid 34 being activated by closure of a switch 39, which occurs when the vehicle gear lever is operated. The master cylinder 10 is, when the solenoid is deactivated, connected to the slave cylinder 48 through the valve 15. The return flow to the reservoir 18 when the clutch engages passes through the valve 15, the master cylinder 10 and a restrictor 19, which controls the rate of clutch engagement. The restrictor 19 may only be operative during vehicle braking (when lower gears are usually selected), this being sensed electrically by a brake-operated switch to activate a solenoid in the restrictor, or by a pendulum which senses deceleration or by fluid pressure from the braking system (Fig. 2, not shown). In a further embodiment the slave cylinder has tandem pistons (Fig. 3, not shown) each being operated by one of the pressure sources. The accumulator 23 is charged by a pump 21 which may be driven by the starter motor of the engine, which motor has means to prevent it from engaging the engine when so used. The accumulator may be dispensed with and the pump 21 driven by an electric motor which operates on energization of the solenoid 34.

The frame is rotated in a tanning bath M. The arrangement is such that the hides, when their suspension edges are in the lowermost position, bend over into the bath as shown at L, the bending being stated to facilitate tanning.

Title: Improvements in and relating to colour photographic processes and materials
IPC: G03C1/805
Filed: 1959-10-23
Abstract: 905,217. Colour photographic material and separation record production therefrom. FRAUNHOFER, H. VON, and FRAUNHOFER, J. A. VON. Oct. 24, 1960 [Oct. 23, 1959], No. 35958/59. Class 98 (2). A base provided with an anti-halo layer is superimposed with, in order, a red-sensitive silver halide emulsion layer, a soft gelatine magenta dye layer, a green-sensitive silver halide emulsion layer, a soft gelatine layer of low melting-point, a yellow filter layer and then a blue-sensitive silver halide emulsion layer. Variations include combining the yellow filter and its adjacent soft gelatine layer, and the provision of an ultra-violet filter layer above such. Procedure therewith involves exposure and normal processing including fixing, treatment of the top layer with a viscous bleach to convert the silver image therein to a silver salt, contacting with a take-off material in the presence of hypo to form a silver sulphide image by reaction as with cadmium, uranium or titanium sulphide provided therein and so produce the blue separation negative, passage of the multi-layer material through warm water to melt the upper soft gelatine layer and remove layers above this; repetition to produce the green separation negative, and leave the red negative on the original base. Separation positives may be made similarly using a reversal technique. An example is directed to camera exposure of the material, describes a loaded ferrocyanide surface acting bleach, and the use of warm urea solutions for the steps of melting the soft gelatine layers. Specifications 795,186 and 796,054 are referred to.

[Also in Divisions F2 and H3] A control apparatus comprises first means for producing a first pulse train by successive integration of an input signal, second means for deriving a second pulse train from the first pulse train at the frequency of the first pulse train, and transducing means actuated by the said pulse trains so that the output signal of said transducing means is a function of the input signal. A unidirectional control signal on a terminal 28, Fig. 2, produces an integrated ramp function which is fed to a circuit 15 having a polarized relay 18, 19 which resets amplifier 8, hence this circuit produces a sawtooth waveform (U 1 , Fig. 3, not shown) of frequency dependent on the magnitude of the control signal and of corresponding sign. The sawtooth waveform is fed to solenoids 31, 32, Fig. 4, the plungers of which are connected to the carrier 43 of a planetary gear so that if gear 41 is stationary, a ring gear 44 attached to output shaft 47 will oscillate, one of two other circuits 22, 23 provide directional pulses (U 2 ) at the instant of closure of contacts 19 which are fed to a stepping motor 33 coupled to gear 41 which compensate for reversal of the carrier so that the motion of the shaft 47 is unidirectional. Cyclic velocity changes of shaft 47 may be smoothed by the control system (not shown) attached thereto.
