Title: Improvements in or relating to braking devices for vehicles moving at high speed over natural ground
IPC: B60T1/14
Filed: 1954-08-04
Abstract: 754,056. Skid brakes. SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES DU SUD-EST. Aug. 4, 1954 [Sept. 26, 1953], No. 22671/54. Class 103 (1). In a braking device for vehicles moving at high speed over natural ground of the kind comprising at least one tooth mounted on a retractable support pivotally mounted on the vehicle to be projected towards the ground for frictionally engaging the ground when the vehicle is to be braked, the support is associated with a device which allows each tooth to be drawn from the ground when engaging a rigid obstacle and allows each drawn tooth to penetrate the ground again after the obstacle has been cleared. In one embodiment of the invention applied to the braking of aircraft take-off carriages of the type described in Specification 740,292 the braking and stopping device comprises a triangular beam structure 1 (Figs. 1, 2 and 3), having a pair of side members pivotally connected at one end to a pair of upper brackets 2 secured to a cross member 3 of the vehicle to be braked and pivotally connected at the other end to a resilient bearing 4. Mounted in the bearing 4 is a shaft 5 which supports a tubular cross member 6 to which ground-engaging teeth 7 are secured. At either end of the cross member 6 a pair of resilient struts 15 is provided. In the inoperative position, the teeth 7 are retracted to the position shown in Fig. 3 and held in place by a catch member device 27, 33. When it is desired to effect braking of the vehicle, cable 44 is pulled, releasing the catch member device and allowing the teeth 7 to engage the ground as indicated in Fig. 2. Should the teeth 7 encounter a resistance exceeding a predetermined amount due to the presence of hard bodies in the soil, the teeth are swung in a counter-clockwise direction and rearwardly thereby elongating the resilient struts 15 by compressing the resilient pads 16 therein and swinging the triangular beam unit 1 in a rearward and upward swinging movement, thus disengaging the teeth from the ground to clear the obstacle and returning them to their ground engaging position when the obstacle has been passed. A modification is described in which the teeth are formed on a plurality of ring members, as shown in Fig. 7, which may be mounted on a common tubular cross member 6 of the structure shown in Figs. 1, 2 and 3. Should the forces acting on the ground-engaging tooth 52, for example exceed' a predetermined limit, i.e. when it encounters a hard obstacle, the tooth 52 will be rotated in the direction of the arrow F together with ring member 51 and the other tooth 53 against the spring- loaded cam members 58 and 59 whereby the obstacle will be cleared and thereafter stop 55 will engage a cam member 59 and cause the other tooth 53 to penetrate the ground. Specification 739,814, [Group XXXIII], also is referred to.

Abstract: 614,808. Photographic printing paper. DIMSDALE, W. H., and ILFORD, Ltd. July 31, 1946, Nos. 22843 and 37547. [Class 98 (ii)] A photographic printing paper has an emulsion containing silver halide in amount between one and seven milligrams per square decimeter calculated as silver. By use of an aromatic primary amino developer and a dye intermediate which will combine with oxidation products formed during development of the silver image to produce an azomethine or quinoneimine dye, an image of both silver and dye is formed, and this image is of adequate density, which would not be the case with a silver image alone of this low concentration. The dye intermediate, and preferably one including a long chain alkyl group or resin group, or one formed in a resinous medium as described in Specification 524,154, may be present in the emulsion itself or in an adjacent layer, so that commercially available developers such as p-phenylene diamine or N.N-diethyl-p-phenylene diamine may be used. Dye intermediates which give a grey or neutral tone, such as described in Specification 542,149 are desirable. An example indicates the use of a baryta-coated paper with a silver chloridegelatin emulsion containing 1-phenyl-4-hydroxy pyrazole-3-carboxylic acid anilide. In a modification developers which are themselves converted to coloured substances, referred to as Howolka developers, may be used; a second example specifies indoxyl carboxylic acid for this purpose and a list of other developers of this type, giving the colours of the images produced by them, is provided.

Title: Improvements in or relating to gas turbine power plants
Inventor: REDDING ARNOLD HURXTHAL
IPC: F02C7/047
Filed: 1952-09-16
Abstract: 709,547. Gas turbine plant. WESTINGHOUSE ELECTRIC INTERNATIONAL CO. Sept. 16, 1952, No. 23228/52. Class 110(3). A gas turbine plant has a de-icing arrangement for passing heating fluid adjacent the air inlet which is connected to cold air and hot gas supply passages of the plant through a control valve which proportions the supply of cold air and hot gas. The de-icing arrangement described comprises a number of hollow guide vanes connected to common inlet and discharge manifolds. Heating fluid is supplied from the plant through a conduit 35 and a control valve 36. The control valve 36 comprises a casing 37 having end plates 39, 40, supporting a stationary rod 41. A sleeve 44 is mounted in the casing to form a gas chamber 45 connected to the discharge of the combustion apparatus 24 by a probe 50 and an air chamber 46 connected to the cooling passage 25. A valve element 52, rotatably and axially movable on the shaft 41 in the sleeve 44, has air ports 55 and hot gas ports 58 which co-operate with similar ports 56, 59 in the sleeve 44 to control the gas flow into the interior 53 of the sleeve from whence it flows to the pipe 35. When icing conditions are encountered, the circuit 93 is energized, and a vent valve 90 opened, this allows the air pressure on the piston 82- to unseat the valve 80 and reduce the pressure in the space 64. The gas pressure in the space 62 then moves the piston 61 and valve element 52 to the left which opens the passage between the chamber 62 and conduit 35. The compressor discharge pressure determines the axial movement of the piston and the valve element 52 while the temperature of the gases flowing through the chamber 62 passing over the element 73 determines the rotary movement.

Title: Improvements relating to hydraulically actuated friction clutches
IPC: F16D48/02
Filed: 1936-08-24
Abstract: 474,539. Operating clutches. WICHTENDAHL, R. Aug. 24, 1936, No. 23246. Convention date, Aug. 31, 1935. [Class 80 (ii)] The piston valve 5 controlling an hydraulically-actuated friction clutch for a motor vehicle is connected with the accelerator in such a way that, on release of the latter, the valve occupies the position shown, in which a conduit 3 leading from an engine-driven oil pump 1 communicates with an air vessel 11 through three passages 8, 9 and 10 of successively-larger cross-sectional areas, while a conduit 12 leading to the pressure chamber 13 of the clutch communicates with a drain conduit 20. On depressing the accelerator, the passage 10 is cut off from communication with the conduit 3 and is placed in communication with the conduit 12, and the conduit 20 is closed, while the passages 8 and 9 still provide communication between the pump and the vessel 11. The clutch therefore engages. On excessive depression of the accelerator, however, the passage 9 is closed so as to restrict the supply to the vessel 11 and prevent the clutch from engaging too rapidly. The clutch may be constructed as described in Specification 451,814.

Abstract: 799,156. Controlling clutches. FICHTEL & SACHS AKT.-GES. July 30, 1956 [July 30, 1955], No. 23441/56. Class 80 (2). A speed responsive hydro-dynamic clutch is combined with a separator clutch automatically disengaged by an electric switch on the gear change mechanism, the separator clutch being held disengaged at low engine speed. A clutch operating relay 6 for a pneumatic, hydraulic or magnetic clutch servo system is energized by a battery 1 on movement of a gear lever switch 5 to disengage the clutch and thus eliminate drag from a combined hydrodynamic clutch. The relay 6 is also energized by closing of a relay 11 when the voltage from the engine driven dynamo 2 is insufficient to hold the switch 12 open, such as would occur with the vehicle at rest or at low engine speed. In a modification, a second winding on the relay 11, shown dotted, acts through a speedometer switch 13 to engage the clutch when the vehicle moves even though the engine is running slowly.
