Abstract: 1,113,236. Valves. PLESSEY-UK Ltd. 15 Oct., 1965 [4 Nov., 1964], No. 44969/64. Heading F2V. [Also in Division B7] A V.T.O.L. aircraft has wing tip and nose and tail nozzles for roll and pitch control, supplied with air through a shut-off valve operated through pneumatic servo-pressure lines, means being provided so that if the servo -pressure lines leading to the valve develop a leak when the valve is in either the closed or the open position the valve is looked in that position. The valve closure 4 has a cylindrical skirt 6 engaging a cylindrical part 7 of the housing and defining a chamber 8 which is in communication with a valve 36 by which it may be vented through passages 12, 38 to open the valve 5 and allow communication between the inlet I and outlets 2, 3, or pressurized with incoming air through passages 11, 37 and 12 to close the valve. The valve 36, is moved by shuttle 13 opposite sides 19, 21 of which are pressurized through restrictions 23, 24 from the passage 11, and is movable by venting one side through a spool valve 31. The shuttle also has auxiliary chambers 20, 22 which are vented respectively by the valve 36 and by a similar valve 39 when the shuttle reaches the end of its travel and the pressure differential between the chambers 20, 22 then holds the shuttle in position even if the pressurized chambers 19 or 21 is vented, e.g. by failure of the lines 25, 28 leading to the spool valve 31. A pilot operated solenoid valve 41, 42 may be used to close the lines 28 and thus the valve 4 can be opened when the line 28 is leaking. The valve 31 is actuated through a worm drive 32, 33 so that the valve 4 is opened when the lift engine 35, or a pivotable engine nozzle is inclined at more than 30 degrees to the horizontal, and is closed when the inclination is less than 30 degrees. The air supply is bled from the engine compressor.

An hydraulic shock-absorbing buffer 100 comprises a piston 101 with a seal 112 and working in a heavy duty cylinder 102 and a hollow piston-rod 105 having a seal 127 and which works in a cylinder extension and pistonrod guide 126 which is secured to the cylinder by bolts 128 and sealed therein by an 0-ring 134. The base 121 of the cylinder 102 carries a hollow metering tube 103 which has openings 118 and extends through the piston 101, internal flats 122 being provided on the tube 103 to allow fluid to flow past a piston stabilizer 110 for a replenishing piston 104 slidable within the hollow piston-rod 105. Return springs 107, 108 are constrained between the replenishing piston 104 and an end wall 106 of the rod 105. During a compression stroke the piston 101 forces fluid from a working chamber 116 in the cylinder to a replenishing chamber 109 in front of the piston 104 by way of the openings 118 in the metering tube, and past the stabilizer and through a conduit 123 with openings 124 therein, fluid also passing to the space behind the piston 101 through a vent hole 117. During a retraction stroke fluid is metered back to the chamber 116 through the tube 103 and through a port 313 in the piston 101 controlled by a one-way valve 114. A filling duct 131 in the guide 126 is closable by a plug 130, the amount of fluid in the shock-absorber being ascertainable by means of a rod 133 which can be introduced through a screw-plugged opening 132 in the piston-rod end wall 106.

Both connecting rods are reciprocated by drives from a shaft 2, the rod 3 via a disc 7 to which it is adjustably pivoted, and the rod 4 via an eccentric disc 8 and follower 81. Marks printed on the underside of the web denote the length of each label and thus the required length of incremental feed step. Most of such a step is effected at the higher speed by rod 3 but the last part is effected at the slower speed by rod 4 so that when a photo-electric cell E detects a mark, the web can be stopped quickly by an electromagnetic brake 9. A ratchet 91 prevents reverse rotation of shaft 1, and a spring 41 in the connecting rod 4 takes up any further movement of the follower 81. Labelling.-Labels cut from the web at J, Fig. 1, are held by suction to a date printing drum F and then to a pasting drum H. The labels are then applied to bottles I.

The device(s) may be PN, P+PN, PNN<SP>+</SP>, PIN, or PNPN wafers. The terminal blocks are of a single conductivity type throughout. An embodiment consists of a stack of silicon PNN<SP>+</SP> wafers, the stack being provided at each end with a low resistivity P-type silicon terminal block. The wafers and blocks are heat and pressure-bonded together using aluminium precoated on the P-type surfaces. Other bonding materials are gold, with or without dopants, and nickel, nickel being used with N-type surfaces and applied by electroless plating. The terminal leads are of copper coated with nickel and gold and are attached to the stack by gold, doped or undoped, or aluminium during the process which bonds the wafers and blocks. The completed stack may be dip-coated in RTV silicone rubber, dip-coated in silicone varnish, and moulded in epoxy, phenolic, or silicon resin. Other forms of encapsulation may instead or additionally use glass with resin and/or varnish, may use oxide or nitride-over-oxide passivation, or may use a hermetic case (in which case the stack may or may not be passivated). Another embodiment is a single PNPN device with one semi-conductor terminal block.

Abstract: 1,017,008. Recoding circuits. STANDARD TELEPHONES & CABLES Ltd. Nov. 22, 1963 [Nov. 27, 1962], No. 46216/63. Addition to 952,804. Heading G4H. In a recoding circuit the data to be encoded is applied to a first matrix and the outputs of the first matrix are applied to a second matrix, the outputs of which are applied in pairs to maximum signal detectors or individually to threshold circuits, the arrangement being such that even though there is a defective connection between the two matrices the correct output data is produced. In the form of Fig. 2a the input data consists of a marking on one of eight leads b0-b7 and the first matrix PM2 consists of admittances at the crossing points each having one of four values 0-3 which govern the signals appearing at the outputs. In the example shown the lead b2 is marked and a pattern of signals appears on the output leads corresponding to the b2 row wire. The second matrix BM2 has resistive junctions designed for recording on the binary scale giving outputs on pairs of row leads for mark and space respectively. Comparators E21-E23 find the higher of each pair. In normal operation the outputs on the row wires are as indicated so that outputs are provided on leads e1, e2 and e3. If a failure occurs in the third lead from the first matrix the outputs of the second matrix are as shown in brackets and the comparators still produce the same output thereby correcting the error. The comparators E21-E23 may be replaced by threshold devices having a threshold level of between 4 and 5 units. The admittances valued 1 in the first matrix may be omitted without affecting the operation of the circuit and as a further simplification the resulting pattern of admittances valued 3 and 2 may be replaced by admittances of a single value as shown in Fig. 4. In the form of Fig. 6 the second matrix is designed to give a two-out-of-five code. The first matrix consists of ten row and ten column wires with admittances at the cross-points having values of 0, 1 or 2. Threshold devices 56 reduce the outputs of the second matrix to binary form.
