Title: Improvements in safety control devices for motor vehicles
IPC: B60K28/00
Filed: 1945-09-26
Abstract: 605,274. Motor vehicles, controlling. DACH, M. Sept. 26, 1945, No. 25002. [Class 79 (v)] A safety device for vehicles or machines propelled by an engine comprises a means for applying increased resistance to the manually operated engine control, said means being normally inoperative but automatically actuated to apply said increased resistance when an unsafe condition exists, whereby the operator is made aware of the unsafe condition but is not prevented from continuing to operate the engine. As shown, the butterfly valve of an engine carburetter 15 is operated by a pedal 10 through a lever 12 and rod 14. An arm 16 is secured to the rod and is dependent therefrom. Mounted adjacent the rod 14 is a cylinder 20 which houses a piston 22 backed by a compression spring 24. A collar 27 is secured to the piston rod 25. The cylinder is connected by a tube 30 to a thermal unit 31 which latter is connected by a tube 35 to the air reservoir 36 of a pressure braking system. The thermal unit which measures the engine temperature contains a valve 32, which, when open allows air to pass into the cylinder, urging the piston against the spring. Should the engine overheat or the air-pressure drop, then the spring moves the piston to the right. In consequence the stop 27 moves into contact with the arm 16, whereby the operator has to exert increased pressure on the pedal to overcome the spring 24 and is so made aware of the unsafe condition. In a modification, two such thermal units are provided, whereby increased pedal pressure is necessary if the engine temperature is below or above a selected working range. In a further modification a spring member is located beneath the accelerator pedal and is operated by a solenoid energized when any one of a number of unsafe conditions exists, viz :-when the engine temperature is above or below a certain maximum or minimum; when the air pressure in the braking system fails; if the engine speed is unduly high; if a door is left open; if the oil level in the. crankcase falls; or if the oil pressure falls.

Title: Improvements in photographic material and method
IPC: G03C1/815
Filed: 1946-08-23
Abstract: 626,319. Photographic relief images. TECHNICOLOR MOTION PICTURE CORPORATION. Aug. 23, 1946, No. 25210. Convention date, May 3. Drawings to Specification. [Class 98 (ii)] A relief image is made in sheet material comprising a base, a layer which is sensitive to secondary radiation and between the base and the sensitive layer a fluorescent layer which emits secondary radiation in response to primary radiation, by exposing the fluorescent layer imagewise with primary radiation, thereby to generate secondary radiation which exposes the sensitive layer from the side of it which is nearest to the base, leaving a portion of the depth of the sensitive layer unexposed and removing this portion to leave the relief image. The fluorescent layer may be exposed through the sensitive layer with primary radiation to which the sensitive layer is insensitive. The base may have the two layers on each side of it, to produce relief images on both sides, of the sheet by exposing the two sides severally to primary radiation, and in this case both primary and secondary radiation should not pass through the base and may be absorbed in the base itself or, as regards the primary radiation, in the incident fluorescent layer ; and dyes, which should be of the fugitive type, in the base or in the fluorescent layers, may effect this absorption or the base itself may not be transparent. The fluorescent layers may be made with a composition comprising gelatin and cadmium sulphide activated with copper, to emit red light when excited with green light, and the photographic layers may consist of gelatin of the bichromate type or may be gelatine-silver halide incorporating dicyanin as red sensitiser and Naphthol Green B for the purpose of confining the exposure zones to the sides of the layers which are nearest to the base. Bichromate layers may be developed by washing with hot water only, silver halide layers require treatment with a hardening developer such as pyro before the hot water wash. The reliefs produced on the two sides of the sheet may represent complemental colour aspects of a scene and may be dyed to produce a two colour picture when viewed by transmitted light, or, for use as imbibition matrices they may represent the same colour aspect so that dye may be applied by passing the sheet through a dye bath, and the dye from the two sides can be transferred to two imbibition blanks simultaneously.

Patent GB-256311-A (GB)
Abstract: 256,311. Igranic Electric Co., Ltd., and Spaink, J. H. A. May 4, 1925. Systems depending on static transformers.-In a system comprising feeder switch mechanism and a variable ratio transformer or other voltage varying device transmitting electrical energy, the means controlling the voltage ratio are automatically operated to minimum voltage position upon opening the feeder switches. The system shown comprises feeder switches S in the primary circuit of a variable ratio transformer T, the secondary winding length of which is varied by a switch arm t<9> and a motor driven screw carrying a notched disc c which co-operates with switch contacts c<2> and motor-controlling solenoids r<3>, l<3> to prevent the switch arm stopping except fairly upon a single contact. The reversible motor M driving the screw is manually controlled by the solenoids r<3>, l<3> and push buttons p<1>, p<2> in circuit with limit switches m<1>, m<2>. A push-button p<3> is adapted to place the motor under automatic voltage-control from the supplied circuit 1, 2. The solenoids r<3>, l<3> have interlocks preventing both closing simultaneously. The motor M and its controlling circuit is supplied from low tension mains L<3>, L<4> through switches S<1> closed only when the feeder switches are closed. When the latter open they close switches S<2> energizing the solenoid l<3> independently of the push button cir. cuit. The motor M is thus operated to lower the transmission ratio, the solenoid circuit remaining closed until the minimum ratio position is reached whereupon the limit switch m<2> opens.

Filed: 1972-06-01
Abstract: 1383539 Light modulating devices PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 1 June 1972 [3 June 1971] 25712/72 Heading H4F [Also in Division H1] A laser capable of producing a two dimensionally scanned output has two electro-optic devices within its resonator which act as controllable masks for polarized light, one device determining the X co-ordinate of the output beam and the other the Y co-ordinate. Fig. 1 shows a degenerate resonator suitable for a scan laser; the optical masks would be positioned at respective focal planes in the resonator, i.e. adjacent one or other resonator reflector, or at the plane 4. One suitable electro-optic device is shown as a sheet 5, Fig. 2, having a grid of wire electrodes 6, 6<SP>1</SP> on each side. The electric field produced may be in the plane of the sheet or across it depending on the individual voltages applied to each wire. The device is used with a laser active medium which gives a polarized output, e.g. a gas tube with Brewster plates, and the voltages applied to the wires set the plane of polarization of the sheet 5 such that light is passed only by a narrow strip of the sheet adjacent a pair of wires to which no voltage is applied, Fig. 3 (not shown). The second device would be arranged with its wires orthogonal to those of the first device. In an alternative device the electric field is applied to sheet 5 by four electrodes positioned as in Fig. 4. This produces a field free region which runs across the sheet (vertically in Fig. 4), the position of this region along the sheet being determined by the relative magnitudes of voltages U 1 , U 2 . The electro-optic material may be KDP, nitrobenzene or liquid crystals. (For Figures see next page.)
