Patent GB-1061880-A (GB)
Title: Fluid flow control apparatus
Inventor: MCCOMBS HOWARD LEWIS
Filed: 1965-11-19
Abstract: 1,061,880. Valves. BENDIX CORPORATION. Nov. 19, 1965, No. 49300/65. Heading F2V. [Also in Divisions F1 and G3] A conduit is provided with first and second orifices arranged in parallel flow relationship and controllable respectively by first and second valve members, the first member being operated by a fluid pressure servomechanism and the second valve member being biased to an open position, the arrangement being such that when the first orifice is closed by the first valve member, the second orifice is closed by the second valve member when the flow through the second orifice exceeds a predetermined value. In the embodiment shown, a valve 60 comprises an inlet 58 supplied by a pump (38) (Fig. 1, not shown), an outlet 54 supplying the after-burner nozzles of an engine (10) via a control unit (56) actuated by a lever (46), and a valve member 102 co-operable with a seating 104. Valve member 102 is integral with a differential-area piston 98 and is provided internally with a chamber 114 having an inlet 113 and an outlet 116, the latter providing a seat for a valve member 120 biased to an open position by a spring 126. When the engine is running at or above a predetermined speed, the main fuel control unit (34) (Fig. 1) provides a signal in line 72 leading to port 154 of a pilot valve 66 controlling valve 60. A branch 74 of line 72 leads to port 156 of valve 66 via a valve (80) controlled by lever (46) and a check valve 158. When the lever 46 selects after-burner operation, and assuming the engine speed is above the said value, the signals at ports 154, 156 of valve 66 cause a spool 144, 146 to move to the left to vent the space 112 behind piston 98 to allow valve 102 to open. Further movement of lever 46 does not affect the pilot valve since the latter is maintained open by the signal in line 72. When the speed of the engine drops below the said value, the signal in lines 72, 74 is lost and spool 144, 146 moves to the right to connect the space 112 to supply via passage 174 restriction 169 and lines 68, 70, thereby causing valve 102 to close. Valve 120 remains open to allow a small cooling flow to the after-burner contact unit 56, but closes if the flow exceeds a value determined by spring 126.

Abstract: 1,161,608. Control of D.C. motors. KENWOOD MFG. (WOKING) Ltd. 5 Sept., 1967 [6 Sept., 1966; 15 Nov., 1966], Nos. 39843/66 and 51217/66. Heading H2J. [Also in Division H1] A motor for driving a hand tool has armature 1 and field windings 2, 3, the motor being supplied from an A.C. source 5, 6, through a controlled rectifier 4. The conductive period of the rectifier is regulated by adjusting resistor 8 by means of a rotatable member, so changing the phase displacement between the currents passing through the circuit 7-9 and the rectifier respectively. A neon tube 11 ensures that the control voltage derived from the circuit 7-9 is of a prescribed amplitude before it is applied to the electrode 12. In another arrangement, the armature and the field winding 3 are arranged on one side of the rectifier, while the winding 2 is on the other side. Alternatively, the armature and field windings are in series with both the rectifier circuit and the variable resistor control circuit. A mains switch is coupled mechanically with the moving contact of the resistor 8. Capacitors are used to suppress radio interference. In another embodiment, the motor is associated with a reversing switch, and a thumb-operated cam is provided to limit movement of contact 20, so limiting the motor torque.

Title: Improvements in or relating to a method of and a device for circulating a liquid at a temperature at or close to its boiling point
IPC: F17C7/02
Filed: 1965-12-03
Abstract: 1,124,589. Separating liquids in pipe-lines. GAZ DE FRANCE. 3 Dec., 1965 [4 Dec., 1964], No. 51383/65. Heading F2N. [Also in Division F1] A liquid at or close to its boiling point, e.g. liquefied gas, is circulated between a storage tank 2 and a supply tank 3 split up into a number of portions in a pipe-line 8 by free independent bodies, e.g. spherical balls, and the mass of fluid between the bodies is substantially constant during the circulation from the storage tank to the supply tank. During the passage of fluid through the pipe-line 8, the gas forms a layer (37), Fig. 2 (not shown), above the liquid (38) between adjacent balls (105 and 106). The balls have a specific weight less than that of the liquid and as they rise from the perforated tube 13 into the pipe 8 they draw liquid from the tank 2 below skirt 35. The balls are released by an anchor mechanism 27 actuated by the passage of a ball 100 beneath a roller 32. Balls rising from the pipe 8 into the perforated pipe 9 are drawn by suction created in the pipe 10 by a compressor (15), Fig. 4 (not shown), into a chamber 11. A pair of discs 40 and 41 having non-aligned holes 43 and 44, respectively, control the entry of balls into the chamber 11 and the return pipe 12 to the pipe 13. The discs 40, 41 are rotated by a turbine 21 driven by the compressor (15). Gas is fed by the compressor into the pipe 12 through a conduit 20 and bubbles through the liquid 1 from the end of the pipe to cause mixing. In a further embodiment, Fig. 5 (not shown), balls having a specific weight slightly greater than that of the liquid are used and the balls are caused to rise in the pipe-line (208) by means of a continuous or pulsed supply of gas under pressure fed therebeneath from a pipe (52). The balls fall under gravity to the region of gas supply. In another embodiment, Fig. 8 (not shown), balls of lower specific weight than the liquid are fed singly into the pipe-line (508) from a collecting device (72) by means of a turbine driven pair of discs (540, 541). The balls may be hollow and of aluminium or of a natural or synthetic expanded material.

Abstract: 1,202,073. Product; difference computing. AMERICAN OPTICAL CORP. 22 Nov., 1967 [1 Dec., 1966], No. 53273/67. Heading G4G. Alternating current analogue signals are combined to a third signal representing product or difference by applying one such signal (or a combination thereof) to a switch input generating a pulse control signal from the other thereof to control the switch operation between conducting and non conducting and filtering the switch output to produce the required signal. In Fig. 1, signals V A  and -V B  of identical frequency in antiphase (e.g. from the photo-cell outputs of a dual beam spectrophotometer) are applied to inputs 10, 12 from which they are algebraically added at junction 14 to produce error signal V s  applied to a switching circuit (Fig. 3, not shown) comprising a transformer fed biased amplifier having a pulsed transistor alternately connecting and disconnecting the input to earth. Input V A  is also amplified to constant amplitude V c  which is applied to control the frequency of the output V o  of a relaxation oscillator 20 according to its instantaneous voltage values, to drive a oneshot multivibrator 22, whose output is thus a sinusoidally frequency multiplied pulse train, to pulse the switch 16 (Fig. 2, not shown), whose output is integrated in low pass filter 24, to a direct voltage V F  which is shown by mathematics to be combined of a constant voltage V R  and a voltage proportional to the product V c , V s . Amplification by differential D.C. amplifier 26 receiving a voltage V R  produces an output proportional to V c , V s  and thus to (V A -V B ) since V C  is constant. This signal may be applied to a null balance servosystem controlling V A  and -V B  for null error. Alternatively the output represents the product of (V A -V B ) V C  where V C  is proportional to V A . Where V A  and V B  are applied directly to the relaxation oscillator and the switch respectively, the output is proportional to the product V A , V B .

IPC: F16G11/12
Filed: 1967-11-28
Abstract: 1,236,930. Tensioning chains. JOHN LAING & SON. 28 Nov., 1968 [28 Nov., 1967], No. 54210/67. Heading B8B. A tensioning device for the haulage chain 10 of a mining machine comprises a cylinder 1 fixable to stationary framework 30, a hollow rod 5 telescopically slidable into the cylinder 1 against the resistance of a spring 7 once liquid is supplied under pressure to a chamber 12 formed between portions 3-6 on the cylinder 1 and rod 5 and a removable chain lock 8 which holds the chain 10 at the outer end of the rod 5 when the liquid pressure is released whereby the chain is tensioned by the expanding spring 7. In mining, one of these devices is positioned at each end of the haulage chain and one of the devices has its spring 7 compressed by using the staked mining machine which is adjacent the other device, as a winch, whereby the rod 5 is telescoped into the cylinder 1 via the chain 10 and lock 8. During this operation liquid is sucked into the chamber 12 from the exhaust line 18. The spring 7 of the other device is then compressed by liquid pressure in the chamber 12 whereafter the chain is locked thereto by lock 8. At this stage the liquid supply valves 14 are closed and the exhaust valves 15 are opened, whereupon the spring 7 of both devices expand to tension the chain, the mining machine is then unstaked ready for haulage. A restrictor valve 16 in the liquid exhaust line 18 ensures that the liquid in the chamber 12 acts to cushion rod 5 during any sudden release of tension in the chain 10. A safety chain lock 9 at the anchored end of each cylinder 1 may be used to aid in maintaining spring compression when the chain is not being used for haulage. In order to release chain tension, the device at one end of the chain has its spring hydraulically compressed and lock 9 is placed on the chain to prevent the device further tensioning the chain whereupon the device at the other end is similarly hydraulically compressed and has a lock 9 put on the chain so that it abuts the framework 30 in the direction of pull. The next step is to remove the lock 8 on the latter device, expand the spring 7 by exhausting the liquid from the chamber 12, re-applying the lock 8 and removing lock 9. This operation with the latter device is repeated until the tension is completely removed. The tension in the chain may be indicated by calibrating the sliding rod 5 or by inserting a pressure-sensitive device between the spring 7 and the end 2-of the cylinder 1, the said device being coupled to a gauge. The chain lock 8 or 9, Fig. 3 (not shown), comprises an apertured plate having guides on one face between which a bifurcated locking bar is insertable.
