Title: Speed indicating systems
IPC: G01P1/11
Filed: 1960-07-18
Abstract: 931,428. Speedometers. M. CABANELASCAMANO. July 18, 1960 [July 31, 1959 ; April 26, 1960], No. 24958/60. Class 106 (3). A system for indicating that a vehicle has exceeded a predetermined speed comprises a rotatable disc 4, Fig. 2, carrying a magnetized element and driven from the driving mechanism of the vehicle at a speed proportional to the speed of the vehicle, the magnetized element serving to rotate by induction a revoluble shutter 5 which is arranged at a predetermined position to interrupt or permit the passage of light between a lamp 7 and a photo-electric device 8 which is arranged to operate a signal when the vehicle has exceeded the predetermined speed. The shutter 5 may have an arcuate slot 6, Fig. 1, for allowing light to fall on the photo-electric device 8 and the lamp 7 may be arcuately adjustable for setting the predetermined speed. The system may be driven by a flexible shaft direct from the vehicle or it may be inserted in the drive to the speedometer. As shown in Fig. 3, the shutter 22 is connected by a shaft 24 to a thin plate 23 which is angularly displaced by a magnetized element carried by a disc 27, the shutter 22 being thus deflected against the action of a spring 26. When the predetermined speed is reached, light from lamp 21 falls on the photo-electric device 18 reducing its internal resistance so that relays 19, 20 act in cascade to operate a signal lamp or buzzer. The arcuate slot in a shutter plate may be replaced by a peripheral gap in a depending flange which otherwise shields the photo-electric device from a suitably disposed lamp, Fig. 5 (not shown).

Abstract: 412,449. Hinges. SIMON, M. S. A., 35, Boulevard Rochechouart, Paris. Sept. 11, 1933, No. 25157. Convention date, Sept. 24, 1932. [Class 65 (ii).] A door hinge comprises a strap whose cheeks form two superposed flat lugs, in the shape of a right-angled triangle, adapted to be fitted in a recess in the door post, and a member having a tenon of similar shape to fit closely into the recess between the cheeks of the strap so as to take up the load on the hinge, the two members having bosses near one corner to receive a connecting pivot pin. Fig. 2 shows the strap member 9, of U-shape in crosssection, which is embedded in the door-post so that its open sides are flush with the surfaces of the door post, and Fig. 1 shows the door member 3, having a tenon 5 shaped to fit between the cheeks 8 of the member 9 ; the member 9 has lugs 10 at the end of one open side to receive a pivot pin, which also engages a corresponding lug 6 on the member 3. The door may overlap the door post up to the lugs 6, 10, so that these are the only visible parts ; in a modification, Fig. 8, the part 5 has attached to it, or formed integral with it, a vertical faceplate 17 which similarly covers the hinge in the case of a door which does not overlap. The Specification as open to inspection under Sect. 91 also describes a modification, Fig. 12 (Cancelled), in which the interfitting parts extend in a vertical plane, the post member 9 being of U -shape in elevation, formed of two face plates connected by a web shown in section, and the door member 3 having a bracket part 5 fitting between the upper and lower parts of the member 9. In the form shown the door overlaps the post to cover the hinge, but in a modification the part 5 carries a cover plate similar to that shown in Fig, 8. This subject-matter does not appear in the Specification as accepted.

Title: Illuminated globe used for educational purposes
IPC: G09B27/08
Filed: 1965-06-15
Abstract: 1,106,553. Globes. A. D. WESTENRA. 15 June, 1965 [22 June, 1964], No. 25264/65. Heading G5G. A device for showing the overhead position of the sun and the area of a planet subject to daylight and darkness at any time of the year comprises a translucent globe formed by two portions, having therein a coloured bulb 7 attached to an arm 5 on the other end of which is mounted a hollow hemisphere 4. The arm is pivotable in a vertical plane about pivot 6. The bulb is positioned in a housing comprising a shroud 9 and a lens 8, so that a spot of light representing the overhead position of the sun will be shown on the globe. The globe is rotatable about axis 2 either manually or by an electric motor 22 driving a friction wheel 23 which engages the surface of the globe. The arm 5 is weighted by a counter weight 12, and the position of the arm can be varied by actuation of a slide 14 attached to one end of a cable 13. Plate 15 (Fig. 4, not shown) has marked thereon the months of the year so that positioning the slide adjacent a particular month will result in the correct overhead position of the sun being indicated. The device also includes a fixed ring 30 which is calibrated to indicate time and the motor is preferably arranged to rotate the globe once every twenty-four hours. The ring may also be rotatable about the axis. In an alternative arrangement (Fig. 3 (not shown)) there is no shroud and the light from the bulb is concentrated by a lens and a drive motor is contained within the globe. The pivotal movement of the hemisphere is effected by linkages. Alternatively the movement of the hemisphere may be effected mechanically via gearing and the motor 22 or by a second motor.

Abstract: 883,968. Jet-propulsion plant. GARRETT CORPORATION. Aug. 9, 1957, No. 25288/57. Class 110 (3). A jet power unit for a vehicle comprises a jet motor attached to the vehicle, means carried by the vehicle for storing liquid fuel having a temperature below the liquefaction temperature of the oxygen in atmospheric air, means supported by the vehicle for providing a supply of liquid oxygen as an oxidant for the fuel, means for raising the temperature of the liquid fuel and oxygen and discharging the fuel and oxygen in gaseous form at about ambient temperature, means for connecting the discharged fuel and oxygen with the jet motor, and means for burning the fuel with the oxygen within the jet motor to produce jet thrust for the vehicle. In the arrangement shown in Fig. 2, atmospheric air is taken in through a scoop 22 and passed through three heat exchangers 19, 27, 32 in parallel to a compressor 47 and a further heat exchanger 13 which cools the air sufficiently to liquefy the oxygen which is collected in tank 37; the cool nitrogen collects in the top of the tank and passes out through heat exchanger 27 and release valve 46 to the atmosphere. The oxygen is pumped from the tank 37 by a pump 39 through heat exchanger 32 and thence to a combustion chamber 21 via a control valve and to the rocket motor 7. Liquid fuel, such as liquid hydrogen, is stored in tank 6 and pumped by a pump 8 through heat exchanger 10, the secondary side of which collects gas evaporating from the tank and after cooling it returns it to an outer shell of the tank (not shown). The hydrogen supply passes from heat exchanger 10 through heat exchangers 13 and 19 to combustion chamber 21 where it is partly burnt with oxygen to drive a turbine 55 ; the partly burnt hydrogen is then fed to the main rocket motor 7 which propels the aircraft. The turbine 55 is connected to an auxiliary power unit 59 which may be a pump, as shown, driving the pumps 8 and 39 and compressor 47, or may be a generator. Specification 814,150 is referred to.

Title: Improvements in or relating to electro-catalytic photography
Inventor: ROBILLARD JEAN
IPC: G03G17/02
Filed: 1964-06-23
Abstract: 1,063,029. Electro-catalytic photography. SCM CORPORATION. June 23, 1964, No. 25875/64. Heading H1K. [Also in Division G2] An electro-catalytic photographic material comprises a semi-conductor and a photoconductive material distributed co-extensively over a surface, the semi-conductor having two oxidation states each of a different colour and being predominantly in the higher oxidation state, the semi-conductor also having a sufficient number of defects in its crystal structure to render it sensitive to the introduction of a relatively small number of ions of a catalyst, in the presence of an electric field, which are trapped in the sites of high negative charge to change said semi-conductor from the higher to the lower oxidation state, or to initiate said change. On exposure to an image conductive paths are formed in the photo-conductive layer, which paths enable an applied voltage to inject catalytic ions into the semi-conductor and thus initiate the change in colour of the semiconductor in a pattern corresponding to the image. Metal oxides are suitable semi-conductors, e.g. those of Ge, Mo, Pb, Ti, V, Ta, Ce, Bi, Cr, Co, Mn, Ni, Sn or W. The semiconductor is preferably doped with a donor impurity to provide the defects, e.g. sodium may be used to dope tin, cerium or titanium oxide. The photo-conductor may be CdSe, ZnO or Sb 2 S 3  while the source of catalyst ions may be Ag, Cu, Mn, Ni or Tl. The photoconductor and semi-conductor may be dispersed as a single layer or as two separate layers. The electrode 12 may be of conductive glass or a transparent non-conductive substance with a conductive layer thereon. The other electrode 16 need not be transparent and may be aluminium or a conductive layer on paper or plastic. The catalyst layer 14 is vacuum deposited and is so thin, e.g. 0À1 Á that is oxidized. A binder, e.g. styrene-butadiene copolymer or polyvinyl alcohol with ammonium nitrate, may be incorporated with the photo-conductor. In a modification the layers 12, 13, and 14 form an integral part, the exposing plate, whilst electrode 16 and semi-conductor 15 comprise the recording paper which can be separated and retained as a permanent record after exposure. In an alternative embodiment Fig. 5, the catalyst layer and transparent electrode are omitted and the positions of the photoconductor and semi-conductor reversed. The photo-conductor retains the image after exposure by lens 42 and is subsequently developed by contact with a silver impregnated roller 45 and the electric field between rollers 45 and 46. With some electro-catalytic photographic materials, the initiated change in oxidation state is further developed by exposure to radiation containing U.V. light, e.g. daylight or fluorescent light.
