Abstract: 665,559. Jet propulsion plant. MAURY, E. J. Oct. 26, 1948 [Nov. 26, 1947], No. 27811/48. Class 110(iii) A gas turbine jet propulsion engine, having combustion chambers supplying gases to a turbine driving a rotary air compressor supplying air to the combustion chambers, has the turbine formed with hollow blades and means are provided to impel water or other vaporizable liquid into the blades through a distributing chamber subject to the heat of the combustion products, the vapour leaving the blades being arranged to impinge on means concentric with the outlet for the combustion products and directed in the rearward direction so as to supplement the jet propulsion force exerted by the combustion products. The gas turbine shown consists of a double intake centrifugal compressor 1 which supplies air to combustion chambers 5 the gases from which pass through the blades 6 of a turbine to a propulsion nozzle. Water is pumped by a pump 7 into the shaft 2 connecting the turbine and compressor through a bearing 9. The bearing 9 has a double stuffing box 11 at each side of a groove 10, from which the water passes through ports 12 into the blind axial bore 13 of the shaft 2. From the shaft 2 the water passes through ducts 15 to an annular chamber 16 and then into the hollow blades 6 where it is evaporated. The resulting vapour is diverted by the wall of the duct 18 into the rearward direction.

Title: Improvements in or Relating to a Sensor for a Braking System
IPC: B60T8/171
Filed: 1978-10-31
Abstract: A sensor for responding to the rate of deceleration of a rotating vehicle wheel includes a flyweight 10 coupleable for rotation in response to wheel rotation and selectively decoupleable in response to the exertion on the flyweight of a torque having a magnitude greater than a threshold magnitude due to a deceleration of the wheel. A control device is operatively connected with the flyweight for exerting on the flyweight torques resisting decoupled rotation of the flyweight and is operable for changing the level of torque from a first level to a second, lower level when said threshold magnitude is exceeded. Occurrence of an excessive rate of deceleration of the wheel is signalled, and the control mechanism is operable in response to such signalling for changing the level of torque and thereby for causing the sensor to signal continuously for the interval during which the threshold rate is exceeded. The resisting torque is applied to the annulus 35 of a planetary gear 12 between input shaft 11 and flyweight 10 by magnetic hysteresis drum brake 20. <IMAGE>

Patent GB-2021826-A (GB)
Title: Dynamic storage apparatus
IPC: G11C11/401
Filed: 1979-05-22
Abstract: The storage space of the instant system is considered, for refresh purposes, to contain 512 groups of 26 bit digital words with each group containing 128 such words. Memory refresh is implemented by sequentially refreshing the groups of digital words at the rate of one group every 2.8 microseconds, giving an expected total memory refresh time of approximately 1.43 milliseconds. A particular digital word from each group of digital words refreshed is read from the memory and transmitted to a parity check circuit which generates fault signals for any digital word having faulty parity. At the end of each of the approximately 1.43 millisecond refresh cycles, the particular word read from each group refreshed is changed so that at the end of 128 full refresh cycles (approximately 184 milliseconds), the parity of every digital word in the memory has been checked. Further, circuitry is provided to store the location of the first failing digital word in a trap register in response to an indication of faulty parity.

Title: Liquid metal cooled fast breeder nuclear reactors
IPC: G21C15/02
Filed: 1979-08-21
Abstract: A liquid metal cooled fast breeder nuclear reactor wherein the breeder sub-assemblies each incorporate a fluidic flow control valve 31 for regulating the rate of flow through the sub-assembly. A governing component for the valve is derived from a minor fraction flow driven by an electromagnetic flow coupler 30 associated with the main flow. The minor fraction flow is influenced by a temperature sensitive electro-magnetic braking device 24 to generate a back pressure which controls valve 31. Alternatively, the flow coupler is itself temperature sensitive and the pressure generated thereby in the minor fraction flow acts as the control pressure for the control valve. <IMAGE>

Title: Spare wheel carrier
IPC: B62D43/04
Filed: 1980-02-08
Abstract: A spare wheel carrier for a truck comprises a bracket (3) mounted on the truck, a threaded supporting rod (5) threadedly connected to a bearing 4 in the bracket for movement along an upper part (5a) of the rod (5) between raised and lowered positions relative to the bracket (3). A wheel 11 is connected to the lower part (5b) of the rod (5) by a nut assembly (10) comprising a threaded part (12) and a disconnectable spider 13 which can be bolted to the bracket (3). To remove the wheel the nut assembly is lowered along the lower part (5b) of the rod (5). Continued rotation lowers the rod from the bracket (3) and brings the wheel into contact with the ground (20). Continued rotation releases the spider (13) from the threaded part (12) and allows it to be withdrawn through the wheel centre. <IMAGE>
Patent GB-2049931-A (GB)
Title: Gyroscopic direction apparatus
IPC: G01C21/16
Filed: 1980-02-28
Abstract: Vehicle heading reference apparatus comprises a two-axis rate gyro (18) and an accelerometer (14), both mounted on an azimuth gimbal (12) which is rotatable about a vertical azimuth axis (z<C>) from a position in which the gyro spin axis (z<G>) is at a zero position to a position at 90 DEG  thereto. One input axis (x<G>) of the gyro is parallel to the azimuth axis, and the other input axis (y<G>) is normal to the spin axis (z<G>) and to the first input axis (x<G>). The input axis (16) of the accelerometer (14) is parallel to the spin axis (z<G>). The apparatus operated in two modes, namely a "northing" mode and a "heading reference" mode. In the northing mode the azimuth gimbal (12) is rotated with a roll gimbal (10) about the longitudinal axis (x<F>) of the vehicle so that the azimuth axis is in a vertical plane through the longitudinal axis (x<F>), and a computer (52) computes an initial north deviation from gyro and accelerometer signals obtained at the two azimuth gimbal positions. In the second mode, the azimuth gimbal (12) is orientated with the roll gimbal (10) about the longitudinal axis (x<F>) of the vehicle so that the azimuth axis (z<C>) is parallel to the vertical axis (z<F>). In this mode, with the azimuth gimbal in the 90 DEG position, the computer computes the heading from the gyro angular speed signals. <IMAGE>

Title: Method and apparatus for handling successive sheets to be stacked in a pile
IPC: B65H31/34
Filed: 1981-01-20
Abstract: A piling assembly for a sheet stacker utilises air pressure directed downwards onto a sheet being transported from a conveyor 20 on to a pile 31 formed against a backstop 32. The assembly preferably comprises a plurality of telescoping rods 53 which overlie the sheet pile and issue air jets in a downward and lateral direction on to the upper surface of a sheet 10b so as to corrugate and therefore stiffen the sheet. The mechanism further includes a lift means 58 situated beneath the sheet and directing air against the undersurface of the sheet, so that the sheet can float over the pile as the sheet is jogged against the backstop 32 in the stacker. The backstop 32 is made movable and the telescoping rods 53 are adjustable to accommodate various lengths of sheet in the stacker. <IMAGE>

Title: Plastics tube fitting
IPC: F16L37/133
Filed: 1981-01-23
Abstract: A fitting 18 for securing the end of a plastics tube 12 in a connector 8 comprises a rigid tubular member 20 having arms 36 with detents 38 for holding the fitting in place in the connector. To anchor the tube 12 in the fitting 18, the member 20 has two sets of inwardly projecting barbs 26 and 28. The barbs 26 are of greater axial extent but radially shorter than the barbs 28 and are accordingly stiffer than the barbs 28. The barbs 26 bite into relatively hard plastics tubing and hold it in place, but relatively soft tubing tends to flow around the barbs 26 so that it is not properly gripped. The relatively soft tubing deflects the softer barbs 28 axially inwards as the tube is pushed into the fitting and then if an attempt is made to pull the tubing out of the fitting, the barbs 28 bend back and bite into the tubing and so anchor it in place. The fitting is thus capable of gripping plastics tubing of a wide range of hardness. <IMAGE>
