Title: Improvements in or relating to pneumatic shuttle-conveying systems
IPC: B65G51/32
Filed: 1969-11-26
Abstract: 1,245,847. Pneumatic despatch apparatus. SIEMENS A.G. 26 Nov., 1969 [27 Nov., 1968], No. 57764/69. Heading B8A. In a pneumatic shuttle-conveying system, each station may act as a despatch, receipt or through station and is provided with a single slide valve which can be introduced into the internal cross-section of the conveyer tube for the receipt of shuttles, whereby a decelerating cushion of air builds up between the incoming shuttle and the valve. As shown, stations 2, 3 are located in vertical conveyer tube sections 4, 5 and are provided with slide valves 2a, 3a actuated by electromagnets 2b, 3b. The electromagnets and travel contacts 2d, 3d are connected to bi-stable store devices 2c, 3c. As a shuttle approaches station 2, it actuates the contact 2d and thereby causes the slide-valve to be actuated after the passage of the shuttle. The shuttle then falls back and is decelerated by an air cushion as it approaches the slide valve. As a shuttle approaches station 3, it actuates the contact 3d to close the slide valve 3a and a decelerating air cushion is formed between the falling shuttle and the valve. In a second embodiment, Fig. 2 (not shown), a station in a single-tube system for alternating operation is provided with a single slide valve and two travel contacts. Both travel contacts are located above the valve, the lower one being adapted to be actuated by shuttles arriving at the station from below and the upper one being adapted to be actuated by shuttles arriving from above.

Title: Injection-type frequency-locked oscillator apparatus
IPC: H03B9/12
Filed: 1971-12-14
Abstract: 1312387 Synchronized oscillators NIPPON ELECTRIC CO Ltd 14 Dec 1971 [14 Dec 1970] 58032/71 Heading H3T An injection-type frequency-locked oscillator comprises a controlled oscillator 4 having an output terminal 5 for connecting to a load 7, and a terminal 14 for coupling to an injection input 1 via a directional coupling circuit 3, there being an impedance mismatch at terminal 14 so that the total power output appearing at a monitor terminal 13 is indicative of the phase difference between the portion of the injection input signal reffected at 14 and the oscillator output also appearing at 14. When the frequencies of the input 1 and the oscillator 4 are equal, the two signals appearing at 13 are out of phase by 180; and for a given input power level, the output power at 13 becomes zero. If the frequency of 4 deviates from the locked condition, there is a departure from the 180 degree phase relationship and the power output at 13 increases until oscillator 4 falls out of lock. The embodiments shown in Figs. 5, 6 involve a transistor 20, a Gunn effect diode 38 respectively as the active element of the oscillators using cavity resonators 15, 37 as the resonating element. The desired impedance mismatch to the input signal being provided by a coupling loop 32 or by an appropriately dimensioned coupling window in the resonator 37 respectively.

Title: Self-locking one-piece metal castel nut
IPC: F16B39/284
Filed: 1970-12-08
Abstract: 1324549 Self-locking castle nut AMERACE ESNA CORP 8 Dec 1970 [9 Dec 1969] 58287/70 Heading F2H In a self-locking one-piece metal castle nut 10 comprising a thin-walled, internally threaded tubular body 12 provided with wrenching faces 26, the thread 14 extending the length of the body, a radially outwardly projecting flange 20 at one end 16 of the body and preferably of an axial depth sufficient to encompass at least one full turn of thread, and at least one pair of axially extending diametrically opposed slots 30 in the body wall adapted to receive a cotter pin, portions 36 of the body, located axially between the flange and the end 32 of at least one slot, are permanently deformed radially inwardly with respect to, and are thinner walled than, adjacent surrounding portions of the body 12 to provide thread portions 38 such that when the nut is threaded on to a bolt the deformed portions 36 are resiliently deflected outwardly to grip and lock the nut and bolt together. The portions 36 are preferably not diametrically opposed since if an end of a diametral hole, for receiving a cotter pin, of a coacting bolt, engages a portion 36, the locking effect is lost. In the embodiment of Figs. 4-6 (not shown), the nut (110) has deformed portions (136) which are circumferentially extended to be wider than the slots (130) to minimize this reduction in locking effect so that the applied installation torque is more nearly constant. In Figs. 7 and 8 (not shown) a "double hexagon" headed nut has deformed portions (236) located beneath projections (234) rather than beneath slots (230).

Title: Improvements in or relating to data-processing systems
IPC: H04M3/00
Filed: 1969-12-01
Abstract: 1,245,485. Automatic exchange systems; data processing. SIEMENS A.G. 1 Dec., 1969 [2 Dec., 1968], No. 58557/69. Heading H4K. Processing of call connection data in a telephone exchange system involves control circuits S1 to Sm and circuits such as allotters U1, U2, transfer of data between a control unit and an allotter being effected in response to a demand from the allotter by way of a circuit individual demand wire in a cable uz, demands existing in the cable uz being detected by a scanner distributor Z1 which gives access to a data bus system US, SU for the data transfer. Once a bus is seized for a demand the identity of the calling unit and/or the wanted unit is sent over the bus to engage the service of the control unit. If such a data transfer is required at the instance of a control unit S1 to Sn, a demand is made direct to the wanted allotter over an individual wire of the cable Sm. The allotters contain scanners whereby the demand is detected along with the identity of the calling control unit and the allotter can seize the data bus as described above. Markers M1 to Mm similarly gain access to a bus system MS, SM over demand wires mz supervised by a distributer Z2, or in response to a demand over cable Su, to exchange data with a control unit. Demand wire cables mz<SP>1</SP> and uz<SP>1</SP> allow the bus systems US, SU, and MS, SM, to exchange roles from time-to-time so that the allotters and markers are alternately served by one and the other bus. If one bus system fails the other bus system can serve both allotters and markers. The bus systems have separate GO and RETURN loops connected from send to receive circuits in the distributers Z1 and Z2. Allotters and markers are coupled by transformers in shunt across each transmission pair while control units are coupled to transformer windings in each leg of each pair, Fig. 2, not shown. Processing of a particular connection involves a series of data transfers over the bus system each transaction being interleaved with similar transactions conducted on behalf of other connections.

Abstract: 1475874 Jet propulsion plant HAWKER SIDDELEY DYNAMICS Ltd 20 June 1974 [21 March 1973 21 March 1974] 59041/72 and 12552/74 Heading F1J In a missile electrical power for guidance and control systems is produced by an M.H.D. generator. In one arrangement a gas generator 11 is fed via pipe 13 with monofuel, e.g. iso-propyl nitrate, seeded with particulate matter such as a potassium compound. Some of the resulting combustion gas flows via duct 14 and valve 29 to control surface actuators 30 of the missile before exhausting into jet efflux duct 22. A further portion of the gas flows via tapping 15 to drive the fuel pump and the remainder flows via tapping 20 and restrictor 21 into efflux duct 22 and through the magnet of an M.H.D. generator 23. The magnet is protected by an insulator 24. The electrical output 27 of the M.H.D. generator is compared with a reference signal 28 and the difference 28a is applied to means for displacing valve 26 to control oxygen addition from source 25 and thus the power output. The oxygen may be pre-heated by heat exchange with the combustion gas. A piston and cylinder device 31 may inject a stream of water/methanol coolant into the ionized gas exhausting from duct 22 to prevent detection. When the magnet of the M.H.D. generator is associated with the main propulsion duct of the missile, then directional control of the latter may be achieved by biasing the gas stream by applying signals from the target detection system to selected field coils. The magnet may be shunt wound or of permanent type and may be cooled by coolant supplied by an umbilical connection to a launch vehicle. The M.H.D. generator may be associated with the propulsion gas stream of a ram jet, pulse jet, liquid or solid fuel rocket, liquid/gas propulsion unit or a gas turbine engine.

It is stated that a smooth broadband frequency characteristic may be obtained if the restricted length of the cavity is about 0À3a where a is the H-dimension of the waveguides.
