Abstract: 1,233,103. Bearings. NATIONAL RESEARCH DEVELOPMENT CORP. 20 May, 1969 [28 May, 1968; 20 Aug., 1968], Nos. 25432/68 and 39804/68. Heading F2A. A bearing comprises a layer of bearing material adhered to a backing member 17, the bearing material comprising lengths of a non- woven yarn disposed beside one another and set in a resin matrix with the bearing surface standing clear of the matrix. Preferably two different types of yarn, e.g. P.T.F.E. or carbon fibre are helically wound in or on a metal backing member and bonded thereto by an epoxy resin. The bearing may be made by winding the yarn on a former, applying a curable resin, assembling a backing shell over the yarn, curing the resin so that the yarn adheres to the backing shell, and removing the former. If the bearing surface is to be formed on the outside surface of the backing member, the yarn is wound on to the backing member and impregnated with resin, a former is slid over the yarn, the resin cured and the former removed.

Abstract: 1,233,155. Mechanical calculating apparatus. BURROUGHS CORP. 18 June, 1969, No. 30922/69. Heading G4B. A multi-bit mechanical store, having pneumatic write-in and non-destructive read-out, comprises a pair of discs 18, 20 fixed on a rotating shaft 10. Each disc has an annular row of holes 24, 26, pairs of holes being aligned as shown and containing a ball 28. The discs are separated by a gap 22 and have a cover 30, 32 having annular rows of ports 34, 36. To write data into the store, as each pair of ports passes nozzles 40, 50 a pneumatic pulse from one of the nozzles directs the ball into the opposite hole 24 or 26 to represent a stored 0 or 1 bit, res ectively. The ball seats against port 34 or 36 owing to rotation of the discs. To read out the stored data pneumatic pressure is applied to gap 22 via a bore 14 in the shaft 10, the fluid escaping via those ports not seated. As each pair of ports passes transducers 56, 58 the escaping fluid causes pressure rise in one or the other transducer so that a diaphragm 64 or 66 is displaced, moving magnet 68 or 70 within coil 72 or 74 to produce a pulse representing a stored 1 or 0 bit, respectively.

Abstract: 1,238,623. Radio receiving arrangements. MAGNAVOX CO. 2 Feb., 1970 [24 Feb., 1969], No. 4852/70. Heading H3Q. A search tuning system for a television receiver having a tuner operated by a tuning motor comprises an energizing circuit for the motor, a relay actuatable for completing the energizing circuit and having an energizing coil, a source of voltage, a control circuit connecting one end of the coil to the source of voltage, means for connecting the other end of the coil to a point of lower potential for energizing it, and control means including the control circuit operable in response to an increase in the D.C. voltage present in a sound demodulator tube means for interrupting the supply of voltage from the source to the one end of the coil to deenergize it. The V.H.F. tuner of a television receiver is rotated by rotor 10 of a motor, coil 1 of which is energized from relay contacts 16, 18: closure of an associated local or remote push button biases the base of transistor T1 positively, causing saturation and energization of relay coil 22. Rotor 10 also drives a Geneva mechanism which closes blade 44 on contact 42 whereby the motor is maintained energized in tuning from one channel to the next. Rotation also causes the closing of moving contact 36 on contacts 34, 38 to apply a muting bias via line 40 to an audio stage of the receiver The U.H.F. tuner may be rotated in either direction by means of a second motor having rotor 50 and coils 52, 54 energizable by means of relays 68, 72 respectively, under control of transistors T2, T3 respectively: rotation of rotor 50 likewise mutes the receiver by means of switch 86. If an audio signal carrier is present in the channel to which the arrangement becomes tuned, the potential drop across resistor 114 in the circuit of a sound channel detector increases. This biases Q3 to conduction, reducing the collector potential and causing a bi-stable circuit comprising transistors Q1, Q2 to reverse: this lowers the potential on line 24 to deenergize that of the relay coils 22, 68, 72 which is energized. Relay coil 104 controls a switch 110 to provide for turning off the receiver in response to a signal from the remote control, which biases transistor T4 conductive, or in response to the building up of a predetermined voltage on capacitor 102 which occurs in the absence of a sound I.F. carrier. In a first modification (Fig. 2, not shown) the emitter bias of transistor Q3 (Q6) is derived via a resistance network including a varistor from the cathode circuit of the audio output valve. In a second modification (Fig. 3, not shown) this bias is derived from the voltage drop across the resistor (186) in the circuit of the sound channel detector via a long time-constant circuit, the bias on the base being derived over a short time-constant circuit.

Abstract: 1316452 Gas turbine engines DEFENCE SECRETARY OF STATE FOR 5 Aug 1971 [14 Aug 1970] 39173/70 Heading F1G A gas turbine engine comprises a rotor member, a shaft to which the rotor member is connected and which is supported in bearings which allow freedom for axial thermal-expansion of the shaft, the rotor member being spaced from a sealing member supported in static structure at a first radial plane of the engine by an axial sealing clearance, and the shaft being mounted on a member which is located in static structure at a second radial plane of the engine, the member being made of a material having a lower coefficient of thermal expansion than the shaft. In the by-pass gas turbine engine shown, the H. P. compressor rotors 7 are connected to the rotor of the H. P. turbine 13 by a shaft 14 supported by roller bearings 15, 16 which permit axial displacement due to thermal expansion. Endwise location of the shaft 14 is effected by a tubular member 20 which is attached to the shaft by a coupling 23 at a position between the rotors 7 and the rotor 13 and is located at its upstream end by a ball bearing 21. The member 20 is of a material having a lower co-efficient of thermal expansion than that of the shaft 14, whereby axial movement of the turbine rotor 13 relative to adjacent parts of the casing is reduced, so that a closer clearance between sealing members 17, 19 can be maintained. For the purpose of maintaining the temperature, and therefore the thermal expansion, of the member 20 at an accurately known value, air at a known temperature is bled from the compressor and supplied to the space 31 between the member 20 and a surrounding tube 32. Similarly, the portion of the engine casing surrounding the combustion chamber 11 may be of double-walled construction 40, 41 to provide an annular space 44 supplied with air at known temperature bled from the compressor. This air is exhausted via holes 45, 46 into the by-pass passage 5 or may instead be used for cooling hot parts of the turbine. The outer wall 40 is of the same low expansion material as the member 20, while the inner wall 41 is anchored at its downstream end and supports the stator of the H.P. compressor 6 through a sliding joint 43. To provide sealing where the burners 10 pass through the walls 40, 41 despite relative thermal expansion between the walls a sleeve 60 is screwed into a threaded aperture in the wall 41 and a cup 61 is dispersed between a shoulder 62 on the sleeve and the wall 41. The cup can slide axially relative to the sleeve and radially relative to the outer casing.
