Title: Improvements in or relating to brakes for vehicles
IPC: F16D65/22
Filed: 1938-10-06
Abstract: 520,034. Drum brakes. CLEVELAND, F. J., (Hydraulic Brake Co.). Oct. 6, 1938, No. 29011. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 11, 1939.] [Class 103 (i)] A brake comprises two shoes 14, 16, Fig. 1 having an adjustable anchor 28 between one pair of ends and anchor blocks 126, 128 slidable in guides, adjustably connected to the other ends. Between the anchor blocks is an operating-cam 142 and between the other ends of the shoes is an alternative operating cylinder 34. The cylinder has two pistons 62, 102, Fig. 5, and an intermediate floating piston 84 provided with an axial channel 94 containing a one-way valve 98, and a plurality of spaced channels 100. Pressure liquid is supplied to the cylinder through the passage 50. On operation of the brake by the cylinder the shoes are applied by the respective pistons 62; 102 the 'cylinder chamber 40 being supplied at first through the passages 100 until the piston 84 is moved against the action of spring 72 thus seating the end of this piston in a port 48. Further liquid then flows to the chamber 40 past the non-return valve 98 and is thus trapped in this chamber. The shoe 14 being a leading shoe and thus exerting the greater braking force tends to move the drum sideways but this is resisted by the trailing shoe 16, inward movement of which is prevented by the trapped liquid. When the pressure is reduced to release the brake, the piston 84 returns to permit return of the liquid in chamber 40. When the brake is applied by the cam 142 the shoes are moved by the blocks 126, 128 through the pins 132 which are eccentric to their pivots on the blocks and can be turned for adjusting the shoes. In this case the shoes anchor on pins 26 on adjustable parts of the anchor 28.

Abstract: 322,841. Bartlett, B. G. W. Oct. 10, 1928. Variable-speed epicyclic gearing comprises a train of toothed wheels b, g, j, Fig. 1, the intermediate one g being floating or unsupported by a spindle, being automatically wedged or drawn in between the other two as described in Specification 221,580. The gear b is fast on say the crank axle a of a bicycle.

When a clutch sleeve w is moved to the left, it engages dogs on the gear b so as to effect solid driving. When the sleeve w is moved to the right, the gear 2 is anchored by the detent, and the train rolls round on it yielding a reduced speed. Control is effected by turning a drum u by a cable. The invention resides in ball bearing races arranged as abutment surfaces for the toothed gears.

IPC: B64C27/18
Filed: 1964-07-20
Abstract: 1,055,328. Gas turbine engines. ROLLSROYCE Ltd. July 13, 1965 [July 20, 1964], No. 29417/64. Headings F1G, F1J and F1T. A gas turbine engine comprises a first shafting on which is mounted a compressor and a turbine of the engine, a second shafting on which is mounted a further turbine, there being means for maintaining the relative speed of the first and second shaftings substantially constant at all times. The invention is described with reference to a gas turbine ducted fan engine suitable for mounting at the tip of a helicopter rotor blade and comprises a compressor 14, which comprises axial-flow and centrifugal stages, combustion equipment 20 and a turbine 21 which drives the compressor through shaft 23. Downstream of the compressor drive turbine is a separate turbine 22 which is mounted on a shaft 24, and carries fan blades 25 at its periphery, the fan blades being disposed within a duct 26 formed between the outer casing 12 and inner casing 13. The two shafts 23, 24 are designed to rotate in opposite directions so as to eliminate gyroscopic forces. The area of the propulsion nozzle is controlled by means of a plurality of flap members 31 pivotally mounted at 32. The shafts 23, 24 each carry a sun gear 33, 34, the relative sizes of which correspond to the relative design speeds of the turbines 21, 22. Engaging with the sun gears are planet gears 37 which are carried by a planet carrier 36, a projecting arm of the planet carrier being connected through linkage 41, 44 to the nozzle flap members 31. The arrangement is such that when the relative speed of the shafts is at the designed value the planet carrier is stationary, but in the event that the relative speeds vary, the planet carrier rotates in one direction or the other causing the flaps 31 to move either to increase or to decrease the area of the nozzle whereby the speed of the two shafts is restored to the predetermined relative ratio.

Divided out of 473,198 under which a Specification was laid open to inspection under Sect. 91 of the Acts, Oct. 9, 1936. [Class 138 (i)] A dish-washing machine comprises a motordriven pump adapted to force liquid from a tank through one or more oscillatory pipes with upwardly-directed nozzles along the length thereof, the pump, tank, and nozzles being arranged below the dishes so that they are sprayed exclusively from below. In the construction shown, a casing 3 is provided with two tanks 4, 5, the tank 5 for rinsing liquid enclosing the tank 4 for washing liquid. The tanks 4, 5 are in communication respectively with pumps 8, 9 coupled to an electric motor 7. The outlet 11 of the pump 8 is connected to a spraying device 12 comprising hollow arms 12a, 12b provided with spray nozzles 35. The device 12 is rotatably and detachably mounted by means of an extension 14 inserted in the pipe 11, and may be oscillated mechanically or, as shown, by means of the reaction pressure of a jet issuing from a nozzle 15. The jet strikes a reflecting member 17 which is adapted to be shifted by means of abutments 16 whereby the direction of motion of the device 12 is reversed at intervals. The rinsing liquid is sprayed from pipes 19, 19a. The dishes are arranged above the spray nozzles in a basket 13 enclosed in a cover 22 provided with reflecting surfaces 32 to disperse the liquid thrown up by the spray nozzles. While one pump is in operation the other is shut off from a supply of liquid by means of one or other of flap valves 25 adjustable from outside of the casing 3. The tank 4 is provided with a strainer 5 and an overflow pipe 29 removable for draining purposes. Specification 473,198 is referred to.

Abstract: 765,598. Television. PHILIPS ELECTRICAL INDUSTRIES, Ltd. Oct. 14, 1954 [Oct. 15, 1953], No. 29629/54. Drawings to Specification. Class 40 (3). In a sequential colour television system a single carrier wave is modulated in turn by two signals the first of which is the green signal and the second of which comprises the red signal, together with the blue signal, the latter being transposed in frequency by means of an auxiliary carrier such that the spectra of the blue and red signals do not overlap sufficiently to prevent correct separation at the receiver. The definition of the blue signal is considerably lower than that of either the green or the red signal and the overall band-widths of the systems is equal to the pass-band of the green signal, that of the red signal being 20 per cent smaller. For stereoscopic operation the green and red signals may be replaced by black/white " stereoscopic pair " signals and the blue signal replaced by the sound signals. The receiver for colour reproduction may employ: (1) a separate cathode-ray tube for each colour; (2) a single tri-gun tube; (3) a single tube with two guns, one of which is employed for the blue signals, or (4) a two-colour tube with one electron-gun together with a further tube for the third colour.
