Title: Hydrostatic propulsion system
IPC: B60K17/356
Filed: 1975-04-15
Abstract: 1493003 Hydrostatic transmissions CLARK EQUIPMENT CO 15 April 1975 [15 April 1974] 15511/75 Heading F2W A hydrostatic transmission for a vehicle comprises a pump 14 which supplies in closed circuit either two sets of motors, 42, 44 and 76, 78 for four-wheel drive or only motors 42, 44 for two-wheel drive, a further pump 90 connected in open circuit additionally supplying motors 42 and 44 in two-wheel drive. Pump 14 is a variable-displacement reversible swashplate pump and supplies motors 42 and 44 via one side of a flow divider 48 (in forward drive), the motors 76 and 78 being supplied via the other side of divider 48 and a valve 62. The valve 62 has a position 63 in which it permits flow to motors 76, 78, a position 64 in which this flow is returned instead to the pump inlet and a position 65 in which this flow is combined with the flow from the other side of flow divider 48, so that the entire output of pump 14 passes to motors 42 and 44. The outlet of pump 90 (of fixed displacement) passes to a valve 92 which returns this flow to a reservoir 100 except when valve 62 is in position 65 (there being a common control lever 66) when the output passes through a shuttle valve 94 to combine with the output of pump 14, shuttle valve 94 ensuring that the system works equally well in reverse. A further shuttle valve, 96, returns a portion of the return flow to the reservoir through a check valve 98. In an alternative embodiment valve 98 is replaced by a gear pump driven by the same shaft as pump 90, this gear pump metering the return flow to ensure that it equals the output of pump 90 (Fig. 4, not shown). A flow divider 56 is controlled by a push-pull cable 132 from the steerable wheels 12 of the vehicle to allow differential action. The valves 94 and 96 can be replaced by a solenoid operated three-way valve (Fig. 4, not shown). Pump 14 is controlled by push-pull cables from a pedal (Figs. 2 and 3, not shown). A make up pump 116 is provided and anti-cavitation valves and a cooling circuit can also be provided. Hydrostatic braking is possible by returning the pump 14 to zero displacement or reversing it and by switching from twoto four-wheel drive (if in two-wheel drive). The provision of position 64 in valve 62 allows a smooth transition between two- and four-wheel drive to be effected. Pressure relief valves 144 and 140 are provided for the output of pump 90.

Title: Selective electrical switching means
IPC: H01H67/30
Filed: 1973-03-30
Abstract: 1451451 Co-ordinate selectors; electromagnetic relays UNIVERSAL TELEWRITERS (UK) Ltd 7 Dec 1973 [8 Dec 1972 30 March 1973] 56794/72 Headings H1L and H1N A plurality of selectively operable switching elements are arranged in an array of rows and columns to form a co-ordinate switching matrix, each switching element comprising fixed contacts 102, 103, arranged to be contacted by an armature 111 centrally pivoted for movement between the contacts in response to selective energization of conductors 114, 115. A ferromagnetic yoke 116 comprising a plate 117 having pole members 118a, 118a', 118b, 118b' projecting towards the armature is arranged so that air-gaps are formed between the armature ends and these poles. Current passing in conductors 115 produces flux crossing the gaps between armature end 111a and poles 118a, 118a' in the same direction whilst current passing in conductors 114 produces flux crossing these two gaps in opposite directions, so that with selected currents the flux in one gap is cancelled and in the other is strengthened so that the armature is moved to contact one of the fixed contacts. Reversing one of the selected currents caused the armature to move to contact the other fixed contact. The arrangement is bi-stable. In an alternative embodiment, Fig. 4, (not shown), the conductors embrace the yoke and two armatures are provided which rotate in opposite directions when selected currents pass in both conductors. Sets of such armatures can be formed integrally with connecting bus-bars from a metal sheet, and the bus-bars can be supported on glass sheets 27, 28, Fig. 6, together with fixed contacts 54, 56. In this embodiment selected currents in conductors 22, 23 embracing yoke 21c, 21c', causes deflection of the armatures 25, (24) in a hollow 57 in one of the glass sheets 27 to which the armature bus-bar strips are attached. To make the device bi-stable the contacts 54, 56 on the other of the glass sheets 28 are associated with permanent magnets 29 to hold the armature on to the contact. The glass sheets are bonded around their periphery to form a sealed unit. In a still further embodiment, Fig. 8 (not shown), two yokes are associated with a single armature, one on either side of it, and the armature is attracted towards one or other of them according to the currents in the conductors embracing the yokes. The bi-stable feature in this case is provided by a bowed resilient strip on the armature, Fig. 9 (not shown).

Title: Signal-translating system
IPC: H04B3/42
Filed: 1945-06-19
Abstract: 593,662. Pulse modulation. HAZELTINE CORPORATION. June 19, 1945, No. 15653. Convention date, Aug. 15, 1944. [Class 40 (v)] Relates to signal translating circuits particularly applicable to the production of uni-directional pulses from input signals derived from the output of a radio pulse receiver subject to C.W. interference on a different carrier frequency as described in Specification 593,661. These signals may comprise D.C. pulses b, Fig. 3, or A.C. pulses b<11>, Fig. 4, at a heterodyne beat frequency, from a wide-band amplifier following the receiver second detector. They are fed through condenser 66, Fig. 1, to a limiter stage 65 comprising two cathode-coupled diodes 67A, 67B biassed to limit the negative and positive excursions respectively of the input wave. The limited output may be, therefore, pulse d, Fig. 3, or pulse d", Fig. 4, c and c' being the limiting levels. The two triodes 76A, 76B are biassed so that the former is substantially unresponsive to a negativegoing input while the latter repeats both negative-going and positive-going grid voltages. They are coupled by the common cathode resistances 78, 79. The bias of valve 76A is maintained at a suitable value for different signal amplitudes by a voltage developed across resistance 95 by signals fed from its anode through condenser 94 and rectified by diode 77. The signal output from valve 67B is fed through condenser 80 to the grid of triode 76A and a predetermined fraction of the signal is fed from a tapping on the anode resistance 72, through condenser 81 to the grid of triode 76B. When pulse d, Fig. 3, occurs at the anode of valve 67B, valve 76A is unresponsive, but valve 76B repeats the pulse, Fig. 3, curve h, which is fed through condenser 91 to the output cathodefollower stage 90. When pulse d<11>, Fig. 4, occurs at the anode of valve 67B, the negative half-cycles are repeated by valve 76B as before. The positive half-cycles are repeated by valve 76A, as well as valve 76B, and the output of 76A appears in the common cathode circuit 78, 79. The resulting output comprises positive half-cycles of amplitude lying between the amplitudes of the signals applied through condensers 80, 81 to the two grids. The effect of all the half-cycles of the input wave is the production of output pulse h<11>, Fig. 4.

Filed: 1974-04-10
Abstract: 1500713 Valves GULLICK DOBSON Ltd 14 March 1975 [10 April 1974] 15807/74 Heading F2V In a control system for a self-advancing mine roof support a control valve 10 of the type described in Specification 1,261,129, is effective to connect ports 13, 14 so that a port 39 of a valve device 11 is connected to a pressure line 47. Fluid pressure at port 39 acts on a piston 33 of a plunger 30 to move it against a spring loading 36 to connect a port 40, which is also connected to the pressure line 47, to lines 49, 50 to operate the props 20, 21, 22 of the support. The pressure at port 40 also passes check valve 37 to act in chamber 45 on piston 35 so that the plunger is hydraulically locked in the actuated position even if the valve 10 disconnects ports 13, 14. If the valve 10 is moved to connect ports 14, 53 fluid pressure acts on a piston 56. to open check valve 37 and so depressurize the. chamber 45 so that the plunger 30 moves to connect the lines 49, 50 to the exhaust port 42. A plunger 57 is simultaneously actuated to open a check valve 51 to depressurize the forward props 22. When valve 10 is moved to connect ports 14, 58 the plungers 59, 60 are moved to open check valves 51 and depressurize the props 20, 21. In a modification of the valve device 11, Fig. 3 (not shown) a check valve (75) traps the actuating fluid from valve 10 in a chamber (76) to hold the plunger (64) in actuated position. Fluid pressure from valve 10 acting on the larger piston (73) acts to move the plunger against the hydraulic lock.

A cylinder 1 containing piston 5 is secured to a liquid receptacle by a screw cap 2, Fig.1, and has a dip tube 3 and inlet valve 4. In operation, depression of button 7 moves piston 5 downwardly and pressurizes liquid in cylinder 1 until the pressure acting on piston 13 via passages 12, 10a is sufficient to move it downwardly against spring 17 to open valve 16a to produce a pressurized spray without non- atomized drops. Downward movement of piston 5 also opens a cylinder port 18 to vent the receptacle to atmosphere. At the end of the downward stroke, piston 5 enters enlarged section 1a of cylinder 1 which connects the cylinder beneath the piston to port 18 to release the pressure therein and cause valve 16a to close under spring 17. A port 19 vents leakage from the space beneath piston 13 to port 18. Passages 12 may be formed in piston 5 or in cylinder 10, as shown.
