Abstract: 562,368. Reciprocating pumps. TURNER MANUFACTURING CO., Ltd., and GROVES, W. R. April 25, 1942, No. 5558. [Class. 102 (i)]. For the hydraulic transmission of power on aircraft or for presses, two double-acting differential piston pumps are operated from the same source of power during the main part of the transmission of power, one pump being byepassed automatically when the delivery pressure rises to a predetermined value. The pumps may be operated by hand or by power, and preferably the byepassed pump is of larger capacity than the other. In the form shown, two similar pistons D, E are reciprocated in cylinders B, C by the short and long arms f<1>, f<2> of a pivoted lever F, connecting rods d, e, and hollow piston rods e<2> which have a crosssectional area half that of the pistons. Each of the latter has a deep groove e<4> containing a shallower rubber packing ring e' and connected by ports e<5>, e to the spaces below and above the piston. The non-return spring-controlled inlet valves H rest on rubber seatings h<1>. The delivery passage J is connected directly to the cylinder B, and to the cylinder C by way of a passage K with a spring-pressed non-return ball valve k, an annular-passage m<3> in a sleeve m, and the upper part of cylinder B. The sleeve m contains a plunger M which is pressed upwards by a spring m<1>, has an enlarged head m<2>, and has an annular groove m' connected by passages m<5>, m<6> to the inlet G. A passage N leads from the passage K to a space n above the sleeve m so that at a high delivery pressure the plunger M is depressed, the groove m<4> coincides with the recess m<3>, and the cylinder C is byepassed.

IPC: F16F15/129
Filed: 1961-02-15
Abstract: 959,460. Damped resilient couplings. DANA CORPORATION. Feb. 15, 1961, No. 5704/61. Headings F2S and F2U. In a friction damped torsionally resilient connection between the driven hub 10 and the outer plates 24 of a friction clutch plate for automotive transmissions, the initial resisting force of the frictional damping of a series of pairs of buttons 14, 15, interposed with cushion springs 13 in pockets 25 of the outer plate flanges 19, 20, which slide frictionally along radially compressed C-sectioned sleeve springs 16, located in clearance notches 12 in the hub flange 11, is decreased when the cushion springs 13 yield only after a limited amount of lost motion is absorbed, due to the difference in length between the notches 12 and pockets 25, as one of each pair of buttons 14, 15 comes into driving contact with the adjacent end of its notch 12, reducing the frictional damping to that of the remaining movable buttons. The sleeve springs 16 automatically compensate for wear and may be omitted from some of the button assemblies to vary the damping effect. The buttons 14, 15 may be of a stamped sheet metal construction. Specification 706,260 is referred to.

Title: Improvements in or relating to the breaking of electric circuits under abnormal loadconditions
IPC: G11C7/04
Filed: 1943-04-09
Abstract: 564,822. Resistance measurements. STANDARD TELEPHONES & CABLES, Ltd., and CHATTERJEA, P. K. April 9, 1943, No. 5710. [Class 37] [Also in Group XXXVII] A supply S is connected to a load L over series-connected contacts a, b of relays A, B, of which A is shunted by the resistance element R of a thermistor T (vide Bell Laboratories' Record, Dec. 1940, page 106), _the heating element a is in shunt or (as shown) in series with the load. With A, B unenergized and to open, the thermistor is cold, and resistances R2, R3 are adjusted so that A closes a but B is inoperative. Switch K is then closed, a heating current passes, and, if R has a negative temperature-coefficient, its resistance decreases and B closes b, switch K being then released. If the current falls off, B releases b, whereas if the current becomes excessive, R gets low enough to cause A to release a, the circuit in both cases being broken. If R has a positive coefficient, the functions of A, B are interchanged. The invention is applicable to testing, for example, resistances within certain tolerances, the relays A, B being then adapted also to accept or reject resistances. By opening connections X, Y and applying a source to 5, 6, the thermistor element R and relays may be independently energized. After each operation, the circuit can be reset by switch K.

Title: Improvements in or relating to flow-meters
IPC: G01F1/28
Filed: 1947-02-27
Abstract: 631,973. Fluid flow meters. WEBB, R. H. Feb. 27, 1947, No. 5745. [Class 69 (i)] [Also in Group XXVII] To measure the flow of a fluid through a conduit 10, one or more wires 23, 24 forming arms of a Wheatstone bridge circuit are stretched across the conduit so that the variation in fluid flow alters the strain on the wire or wires and in consequence their electrical resistance. The strain may be either longitudinal or torsional as in the case when a disc is eccentrically supported by the wire. The wires may support a drag body 25 or a disc so that the strain in one wire increases whilst that in the other wire decreases. Another wire forming the third leg of the bridge circuit may circumferentially surround the pipe to make any corrections necessary should the conduit be physically deformed. The out-of-balance current in the bridge circuit may be used to control the fuel supply to an internal-combustion engine when the conduit forms the air intake to such an engine.

Patent GB-970220-A (GB)
Title: An arrangement for automatically mixing liquids
IPC: G05D11/13
Filed: 1963-02-15
Abstract: In mixing flowing liquids in proportionate quantities the p  outputs of the pumps feeding the constituents are electronically controlled and the required percentages of the constituents may be set manually on a dial, or by means of a punched card.  A diode matrix is connected to appropriate voltages which are stored and combined by the matrix in such a manner that its output voltages are a measure for the individual quantities of liquid and preset a counter for the number of revolutions or piston strokes of the pumps.  Continuous flow is obtained by metering and mixing a large number of successive batches, each of very small size, per unit of time, the frequency being a measure of the total quantity dispensed.  A control system is described for mixing liquid fuels comprising main constituents, major additives of the order of a few per cent, and minor additives of the order of a few per thousand.

Abstract: 1,015,592. Radio beacons. STANDARD TELEPHONES & CABLES Ltd. Feb. 15, 1963 [Feb. 19, 1962], No. 6331/62. Heading H4D.  A Doppler V.O.R. radio beacon comprises Fig. 1, an odd number of spaced antennµ 4, (five antennµ being shown for convenience, but twenty-five being preferable), occupying one half of a number of equi-spaced positions on a circle, no antenna being diametrically opposite another, means (e.g. capacitive switch elements 6 and 8) to energize the antennµ singly and cyclically from a first source of waves 1, so that the energization cycle travels at a constant speed around the circle, means (e.g. capacitive switch elements 7 and 8) operative on the energization reaching a position in its cycle unoccupied by an antenna to energize the antenna diametrically opposite that position from a second source of waves 2, whereby radiation is alternately of waves from the first source and of waves from the second source, and means to energize a further antenna 9 at the centre of . the circle from a third source of waves 3, the waves from the first and second sources having the phases and frequencies of respective equal order amplitude modulation sidebands of the waves from the third source, the beacon being arranged to transmit a reference signal phasecorrelated with the said energization cycle for its indication to a receiver, and the spacing between adjacent position not exceeding one half of a wavelength at the radiated frequencies. The positions not occupied by the antennµ are occupied by matched loads to absorb the energy of the connected wave source, or alternatively the wave sources may be periodically switched off. To make the beacon compatible with conventional V.O.R. receiving stations, the waves from the first and second sources have frequencies differing from that of the wave from the third source by plus and minus 9960 c/s. respectively, while the waves from the third source 3 are amplitude modulated at 30 c/s. in synchronism with the 30 c/s. energization cycle of the antennµ. In a second embodiment, Fig. 2, all the antennµ 4 are grouped in one half of the circle. The signal received at the aircraft &c. from the antennµ 4 is frequency modulated at 30 c/s. with a frequency deviation of 19,920 c/s. and this modulation may be used as the reference signal. The square envelope of this modulation may be used to produce harmonics to provide fine bearing information as described in Specification 1,003,317. In a third embodiment twenty-five antennµ may be used in five groups of five to produce a square reference wave at a frequency of 150 c/s. Wave energy should be gradually switched from one antenna to the next to avoid transients.
