Title: Improved parity checker
IPC: H04N7/173
Filed: 1959-12-16
Abstract: 935,375. Electric selective signalling systems. SKIATRON ELECTRONICS & TELEVISION CORPORATION. Dec. 16, 1959 [Dec. 17, 1958], No. 12960/60. Divided out of 935,371. Class 40 (1). A checking circuit for use in the subscription television system described in Specification 935,371 which is referred to, performs three checks on a serial train of five different frequencies which should occur in synchronism with five timing pulses. The checks are (1) to check that no two frequencies occur simultaneously (i.e. overlap), (2) to check that not less than five frequencies occur, and (3) to check that not more than five occur. If any one of these checks is not satisfied an output signal indicating an error is produced. The five timing pulses occur successively on five leads 1, 2, 3, 4 and 5, and the serial train of frequencies on an input lead 354. The frequencies are separated by filters and gated with signals A<1>, B<1>, &c. five of which will have been used to control the oscillators producing the five frequencies. The first check (for overlapping) is effected by a threshold amplifier 570. If two frequencies overlap a mixing circuit 566 produces a larger signal than usual which causes the threshold amplifier 570 to produce an error indicating output signal. The second check (for less than five frequencies) is effected by five flip-flops 596-604. When the fifth timing pulse, on lead 5, occurs all five flip-flops should be on thereby opening an and gate 606, inhibiting a gate 610, and thus preventing the fifth timing pulse passing to the error indicating output lead 574. If, however, less than five frequencies are received, gate 606 will not be opened and the fifth timing pulse will pass to the output lead. The third check is similar to the second. In the absence of any timing signals, each frequency signal will pass via or gate 618, and gate 616 to produce an error-indicating output. Each timing signal blocks gate 616 so that if more than five frequency signals occur, or if they occur out of phase with the timing signals, then an errorindicating output is produced.

Abstract: 939,187. Variable-speed epicyclic gearing. FICHTEL & SACHS A.G. April 4, 1962 [April 7, 1960], No. 13044/62. Class 80 (2). [Also in Group XXXI] Back-pedalling of a driving member of a hub change-speed gear engages a free-wheel to cause axial movement of a shift sleeve bearing on a non-rotating thrust block which acts directly on the shifting member of the changespeed gear. A sprocket 8 rigid with a driving member 1 is mounted through bearings 51 on a hub spindle 17 formed with a sun gear 26 meshing with planet gears 25 mounted on a planet carrier 22. The planet gears mesh with a ring gear 7 connected by dog teeth 9 to a pawl carrier 10 having pawls 11 forming a free-wheel coupling between the carrier 10 and the hub shell 13. A gear shift sleeve 4 is splined to the driving member 1 and axially movable against a spring 31 to engage teeth 5 with corresponding teeth 6 or 21 on the ring gear 7 or the planet carrier 22. Back pedal movement of the driving member 1 engages a jamming roller free-wheel 14 to rotate a cam sleeve 15, having sloping teeth 16, to axially move a thrust block 20, in a slot 19 in the spindle 17, engaging directly with an internal shoulder in the shift sleeve 4 to change the gear ratio. The cam sleeve has outstanding ridges 29, 30 to prevent inadvertent change of ratio. The planet carrier 22 may have a threaded engagement with a conical brake member 57 engageable with a brake member 62 rigid with the hub shell.

Title: Improvements in domestic and the like heating systems employing the heat-pump principle
IPC: F25B27/00
Filed: 1951-06-04
Abstract: 705,691. Power generating systems; wind-motors. CAPPS, M. W. R., CAPPS, N. C., and CAPPS, A. W. F. May 29, 1952 [June 4, 1951 ; July 5, 1951], Nos. 13160/51 and 15926/51. Classes 110 (3) and 122 (3). [Also in Groups XI, XIII and XXVIII] Wind-motors, Fig. 3.-The rotating tower 10 of a windmotor contains a transmission shaft 65 vertically reciprocated by link 64, crank 63 and bevel gearing 60, 61 rotated by the rotor 32. The rotor 32 is mounted on the leeward side of the tower so as to be self-setting to the wind. Power-generating systems, Fig. 1.-A wind-motor 32 located on the roof of a building drives a compressor 11 which withdraws water vapour from an evaporator 33 in the tower of the windmotor through a suction pipe 23. The superheat of the steam is removed by a heat accumulator 38 used for cooking and like purposes and by a domestic water heating unit 40 and the saturated steam flows through a pipe 25 to a subterranean storage tank 14 where it condenses. Radiators 43 are provided with low temperature steam from tank 14 which also heats the surrounding ground. If heating is not required in radiators 43, the steam is passed through valve 107 and pipe 106 to a manifold 21 leading to open-ended pipes 21a enclosed by porous pipes 20 located in the ground. The steam thus condenses in and heats the ground. Steam is bled off from the compressor outlet through a valve 51 and pipe 50 to drive a turbine 48 driving an electric generator 49, exhaust steam returning to the suction pipe 23 through pipes 52, 24. Heat is absorbed by the system from the atmospheric air when the ambient temperature is high enough by the evaporation of water in evaporator 33 due to solar radiation and the air stream around the wind-motor tower. When the ambient temperature is low, e.g. in winter, suction pipe 23 is connected to manifold 21 by opening valve 22 in pipe 24 and water is evaporated from the warm ground. According to the second Provisional Specification, a low pressure turbine may be connected to the manifold 21 for power generation purposes.

Patent GB-132203-A (GB)
IPC: G08B5/22
Abstract: 132,203. Schneider et Cie. Feb. 3, 1918, [Convention date]. Addition to 131,635. Order apparatus.-An order apparatus comprises a Wheatstonebridge resistance having two brushes connected through gearing at the transmitting-station, and a similar Wheatstone-bridge and one or more voltmeters at the receiving-station. When two voltmeters are employed, one gives a coarse adjustment and the other a fine adjustment, while when one voltmeter is employed, means are provided for placing it under the control of one or the other of the brushes. The volt-meter circuit may contain resistances adapted to increase or decrease the sensitiveness of the arrangement, and the needle is masked at its extreme positions. The bridge may be supplied with pulsating current in order that a telephone receiver connected in parallel with the volt-meter may warn the operator when the balance of the bridge is upset. The brush A', Fig. 1, is mounted upon the driven shaft p at the transmitting- station, which drives, through redueing-gearing P, P<1>, R', R, a second brush A<2>. The brushes B<1>, B<2> at the receiving-station are similarly driven. The brushes A', B<1> are connected by the circuit D, E containing a voltmeter F, and the brushes A<2>, B<2> are connected by the circuit D<1>, E<1> containing a volt-meter F<1>. When the shaft p is rotated, the shaft q is rotated to keep the needles f, f<1> on the zero readings of the meters. Should, however, the operator at the receiving-station fail to notice the movement of the fine-adjustment meter F, the coarse-adjustment meter F<1> will be moved from its zero position to indicate that the transmitter has been operated. In the modification shown in Fig. 2, a single volt-meter F and a switch T are provided, the arrangement being such that, by means of the switch T, the volt-meter may be placed under the control of the brushes A<1>, B<1> or the brushes A<2>, B<2>. A normally shunted resistance W may be placed in the circuit of the volt-meter by means of a switch w, and a resistance V normally in circuit with the resistance may be shunted by a switch v. A shield U obscures the needle f when in its extreme positions.

Abstract: 885,371. Packaging by banding. VEREENIGDE METAALVERPAKKING MAATSCHAPPIJ N. V. April 13, 1960 [April 18, 1959; Oct. 1, 1959], No. 13248/60. Class 94(1). A machine for banding packages has two gear wheels 16, 17, Fig. 4, that can be closed on the banding means 5 and driven through a slipping clutch to tension the band, the teeth of the gear wheels being reduced in height over that part of their length that is to be occupied by the band to minimize the formation of weak zones in the band. The teeth 45, of the wheel 16, have recesses 46 in their effective flanks such that the sharp edge of the crest of the recessed portion of each tooth is spaced from the teeth 44 of the gear wheel 17. In Fig. 1 the band 5 is fed from a roll 6 to feed rolls 8 and 9, and then around guide members 3, 4, to encircle a package k. The free end of the band is then gripped and an arm 11 is rocked clockwise about its pivot 11a to disengage the feed rolls 8 and 9 from, and to close the gear wheels 16, 17 on, the band 5. The gear wheels 16, 17, driven through the friction clutch then tension the band until the clutch starts to slip. A cam controlled fastening mechanism 42 then punches through the overlapping portions of the tensioned band to form interlocking tongues. The gearing includes means whereby the gear wheels 16, 17 are then moved closer together and the drive thereto is rigidly coupled to the driving shaft 18 instead of through the slipping clutch. The tension in the band 5 then increases until it breaks immediately behind the sealing zone.

Filed: 1950-05-26
Abstract: 679,586. Automatic pilots. BENDIX AVIATION CORPORATION. May 26, 1950 [June 23, 1949], No. 13345/50. Class 38 (iv). In an automatic pilot, the ailerons are controlled by the craft heading detector and the rudder by deviations from the dynamic vertical displacement plus rate of yaw to prevent side slip or skidding. Rudder control, Fig. I.-As shown, a pendulum 11 mounted forward of the craft CG to swing athwartships responds to dynamic vertical displacement (a persistent low-frequency signal) and yaw acceleration (a non-persistent higher frequency signal). The output from the pendulum pick-off 13 is fed in part to a selective ball-and-disc type integrator unit 17 to provide a yaw-rate signal, and in part to a thermal delay low-pass filter unit 42 (such as that described in Specification 679,560) which passes only the vertical error signal. These signals appearing at potentiometers 40, 62 respectively are connected in series to the rudder servo amplifier 74 together with the rudder displacement signal from pick-off 67 in a conventional manner. Alternatively the pendulum casing may be filled with damping oil, in which case the required yaw rate plus vertical displacement signal is obtained directly from the pendulum pick-off, Fig. 2 (not shown), or the vertical component may be obtained from a damped pendulum, or an undamped pendulum at the craft CG, and the rate of yaw signal obtained from a gyro, Fig. 3 (not shown). Aileron control.-The conventional aileron servo system is fed from signal detectors responsive to rate of bank, roll displacement, course setter, compass and radio track, Fig. 4. not shown.

Abstract: 913,805. Supplying liquid fuel to burners. SHELL RESEARCH Ltd. March 17, 1961 [April 14, 1960], No. 13354/60. Class 75 (1). [Also in Group XXI] A safety device in the fuel supply line of a burner 1 comprises a valve 7 spring biased towards a closed position and held open by the pressure of a fire extinguisher capsule 10, and a fusible plug 11 which permits the extinguisher capsule to discharge on undue rise in temperature at the burner 1, thereby allowing the valve 7 to close. The valve 7 (Fig. 3) is slidably mounted within a housing 16 provided with end plugs 17, 18 and comprises piston parts 22, 25, 28 connected by necked parts 24, 27. A pipe 9 connects the extinguisher capsule 10 to a tapped hole 35 communicating with a bore 34 in the end plug 18. The pressure of the extinguisher fluid retains the valve in the open position wherein fuel from a reservoir 3 flows through a pipe 4, a control valve 5, a pipe 6 connected to a passage 19 in the valve housing, round the necked part 24 of the valve and through a pipe 8 leading from a second passage 20 in the housing 16 to the kindler trough 2 of the burner. The fusible plug 11 is disposed within a conduit 12 connecting the bore 34 with a bore 38 in the other end plug 17. When the fusible plug melts extinguisher fluid passes through the conduit 12 to equalize the pressure on opposite faces of the valve and a spring 32 moves the valve to a closed position wherein the passage 19 is closed by the piston part 22. The extinguisher fluid passes through a bore 30 in the piston part 28, a passage 21 in the housing 16 and a pipe 14 leading to a spray nozzle 15 adjacent the kindler trough 2. In another embodiment the stem of a spring-loaded fuel valve is connected to a diaphragm subjected on one side to the pressure of the extinguisher fluid to retain the valve in the open position. The other side of the diaphragm is connected to a conduit leading from the extinguisher capsule to a ring of spray nozzles and containing the fusible plug, so that if the plug melts the pressure across the diaphragm is equalized, thereby permitting the valve to close.
