Abstract: 800,872. Supplying liquid fuel to burners. BENDIX AVIATION CORPORATION. Oct. 24, 1955 [Oct. 25, 1954], No. 30337/55. Class 75(1) [Also in Groups XII and XXVI] Combustion equipment, for example of a starter gas turbine, comprises a combustion chamber 1 having an inlet end portion 5, 9 and an outlet end portion 2 provided with nozzles 3. The equipment is provided with a starting fuel nozzle 27 and main fuel nozzle 31, the latter only being supplied with fuel when a certain pressure has built up in the combustion chamber. The inlet portion of the combustion chamber comprises a portion 5 having an axial bore 6, a central recess 7; and a number of passages 30; also a cup-shaped member 9 which affords a piston chamber 11 and a fuel inlet passage 14. A partition member 8 is disposed between the parts 5 and 9 and a hollow shaft member 18 is slidably mounted therein, also in the end wall 12 of the member 9. A piston 19 is secured on the hollow shaft 18 and the enlarged head 23 of the shaft 18 is held by the spring 17 in contact with the member 5. A starting fuel nozzle 27 is mounted in the axial passage 6, the nozzle having fuel passages 29 and incorporating a fuel supply valve 32. Fuel is supplied by a -pump 16 to the fuel flow restricting valve 10, the fuel then passing through duct 43 to the inlet passage 14 and thence through the passage 15 in the hollow shaft 18. At a certain fuel pressure, the valve 32 is opened against the action of the spring 36, whereby fuel passes through the passages 29 of the starting fuel nozzle 27 and combustion commences in the chamber 1. Combustion gases pass through the narrow passages 26, 25 to the space 24 behind the piston 19 so that at a certain combustion chamber pressure, the piston 19 and the hollow shaft 18 and the head 23 move to the left whereby fuel flows from the passage 15 to the recess 7 and passages 30 to the main fuel injectors 31 and full combustion then occurs. The combustion gases pass through the nozzles 3 to drive the starter turbine 4. The fuel flow restricting valve 10 comprises a hollow cylinder 10 connected to the fuel supply duct 39 at one end and having an outlet port 42 at one side. A sleeve valve 44 having an inturned flange 45 is slidably mounted in the cylinder, a spring 47 being disposed between the valve and a screwed plug 41. The oressure of fuel tends to move the sleeve valve 44 to the left thereby closing the outlet port 42.

Title: A method of pretreating a metallic hydride
IPC: G08B17/06
Filed: 1960-05-25
Abstract: Consistent in- and out-gassing of metal hydrides in closed systems is achieved by heating the hydride in the closed system to outgas hydrogen, cooling to room temperature to reingas as much hydrogen as will reingas, and then withdrawing all excess hydrogen that did not reingas, and then withdrawing all excess hydrogen that did not reingas from the system. The system may then be evacuated and filled with an inert gas. Metal hydrides referred to are those of the alkali and alkaline earth metals, scandium, titanium, vanadium, palladium, ytterbium, zirconium, niobium, hafnium, tantalum, the rare earths and the actinides.  The example describes heating titanium hydride above 1000 DEG  C. by the passage of an electric current, in a closed vessel containing hydrogen at one atmosphere pressure, cooling to room temperature, evacuating the vessel and filling with argon.

Title: Vehicle braking unit
IPC: F16D65/54
Filed: 1962-08-09
Abstract: 984,246. Brake adjusting mechanisms. AIRHEART PRODUCTS Inc. Aug. 9, 1962 [April 26, 1962], No. 30527/62. Heading F2E. In a braking mechanism a a main piston 17 is actuable by fluid pressure in cylinder 13 to engage friction elements 11, 12 and has limited relative movement with respect to an auxiliary piston 19 to which it is interconnected by a stop member 28 movable with the main piston and between spaced abutments 26, 27 on the auxiliary piston. The auxiliary piston is held by a ring member 34 which releases the auxiliary piston for movement in either direction when a predetermined holding force is exceeded. As shown, the limited relative movement of the piston 17 with respect to the auxiliary piston is provided by the ring member 28 which is normally spaced from the shoulder 26 on the auxiliary piston a distance corresponding to the brake clearance 33 and held against a ring 29 by a spring 30. On actuation of the brake and when adjustment is required the ring member 28 is forced against the shoulder 26 on the auxiliary piston by a snap ring 24 in a groove 23 in the piston 17 and moves the auxiliary piston to a new position. Upon release of the brake the spring 30 will retract the piston 17 and again establish the correct clearance 33. If the pad 11 is in engagement with the disc 12 when the piston 17 is in the brake released position, as a result of the installation of new pads for example, and fluid pressure is applied, since the piston 17 cannot move, the auxiliary piston will be moved outwards until the ring member 28 is engaged by the shoulder 26. Built-in clearance is thus automatically re-established. The grip ring 34 may be in the form of an ellipse or of triangular configuration. In another embodiment, Fig. 4, manual adjustment is provided by a bar 46 which can be moved laterally by means of a screw 51 and slide member 48 in a transverse slot 45 in the auxiliary piston. Specification 878,127 is referred to.

Title: Method of effecting the non-destructive readout for magnetic-core storage matrices (learning matrices)
IPC: G06V30/194
Filed: 1963-08-02
Abstract: 1,002,405. Learning networks. STANDARD TELEPHONES & CABLES Ltd. Aug. 2, 1963 [Aug. 8, 1962], No. 30725/63. Addition to 939,134. Heading G4R. In a learning matrix of the kind described in the parent Specification, which comprises an array of cores, the cores of each row being set in a learned pattern, the binary pattern to be recognized is applied in the form of radio frequency currents of one of two phases displaced by 180 degrees, all cores also receiving a second radio frequency current, the match of each stored pattern with the input pattern being represented as a voltage amplitude of a frequency which is the sum or difference of the first and second frequencies. Generator G1 is connected to a split-secondary transformer giving voltages having the same amplitudes but opposite phases T(W1) and T(W1) + 180 degrees. Switches S, which may each be a pair of gates controlled by a trigger, apply the input pattern and each core generates in the corresponding row lead a voltage in phase or 180 degrees out of phase with the applied current according to the state of the core. The best match row will produce a maximum signal having a frequency equal to the difference between the frequencies of the first input current i(# 1 ) and the second i(# 2 ). The worst match also produces a maximum signal but of opposite phase. The best and worst match signals can be distinguished by phase discrimination, e.g. using a ring modulator. In the form of Fig. 1, however, the antiphase signal is cancelled by adding a voltage UZ derived by combining signal i(# 1  and i(# 2 ) in core V. The useful signals representing the extent of the match are separated by selective L-C networks SN and applied to a maximum signal detector.
