Patent GB-917713-A (GB)
Title: Improvements in or relating to lubricating systems
IPC: F01D25/20
Filed: 1960-09-24
Abstract: 917,713. Lubricators &c. CAMMELL LAIRD & CO. (SHIPBUILDERS & ENGINEERS) Ltd., and ROGERSON, J. Sept. 21, 1961 [Sept. 24, 1960], No. 32891/60. Class 12 (3). A lubrication system comprises a pump 10 which feeds lubricant under pressure to bearing lubrication points 11a via manifold 11. Said pump also supplies lubricant to a gravity feed tank 14 via a pipe-line 13 on the discharge side of the pump. Located in the pipe-line 13 is a spring-loaded restrictor valve 15 which permits oil to be supplied to the gravity feed tank 14 and at the same time maintains the required pressure for the lubricant supply to the bung ports. A delivery pipe 17 is connected from the gravity feed tank 14 to low pressure lubrication ports 12a and 12b. Further interconnection is made between pipe-lines 17 and 13 by pipe 16 in which there is located a non-return valve 18. During normal operation the pump 10 supplies lubricant to the bearing ports 11a and at the same time maintains the lubricant level in the gravity feed tank 14, said tank supplying lubricant to the lowpressure ports 12a and 12b. Should the pressure in the pipe-line 13 drop due to failure of the pump, the non-return valve operates to permit lubricant from the tank 14 to pass to the lubricant ports 11a as well as the normal feed to 12a and 12b in order to maintain, for a short period, lubricant at the required points while the machine concerned is brought to rest.
Patent GB-663028-A (GB)
Title: Improvements in or relating to electric synchronised switching arrangements
Inventor: MACMULLAN JOHN SUMNER MUNRO
IPC: H04K1/06
Filed: 1949-12-23
Abstract: 663,028. Phase measurements. STANDARD TELEPHONES & CABLES, Ltd. Dec. 33, 1949, No. 32926/49. Class 37. [Also in Groups XXXV and XL (c)] A switching-pulse generator (e.g. a multivibrator) of variable frequency is synchronized with a train of pulses, by combining the switching pulses with a series of gating pulses (derived from the synchronizing pulses) in such a manner that partial overlap is obtained, and controlling the generator frequency by a voltage varying with the degree of overlap. In Fig. 3, the freerunning multivibrator 18 generating pulses (e), Fig. 5, in the relay 21, is synchronized by pulses fed at 37 to one valve 25 of a multivibrator 14 of the kind having one stable and one unstable condition. The received synchronizing pulses are differentiated and clipped before they are applied at 37 to open the normally-blocked valve 25, causing pulses (f), Fig. 5, to appear at the cathodes of both valves 25, 26 of a duration dependent on the capacity 27 and the associated resistances. These pulses are applied to opposite corners 42, 44 of a diode bridge, the pulses (e) from the generator 18 being applied to a third corner 46, and the output taken from the fourth corner 47. When the generator 18 is running correctly, the leading edges of its pulses (e) coincide with the mid-point of the synchronizing pulses (f), and the output at 47 is of the form (g). The effect of the generator running too fast or too slow is to distort the output (g) to the unbalanced forms shown at (h) and (j) respectively. When these outputs are integrated by the condenser 50, they provide a control bias for the amplifier valve 51, which, by varying the grid voltage on the valves 54, 55, corrects the frequency of the multivibrator 18.

One of the 'third datum points' 42 to 50 corresponds to the number of tests, 2 to 6, to be carried out on each sample, and the number of the sample receiver positioned at the selected datum point at start-up is that used to pre-set the register. The rates of advancement of the receivers 14, 24 are then such that number of the sample receiver at the sampling point 18 at start-up is shown on the register when the test portions of this sample in receivers 24 reach the testing station 38. 36 is a reagent addition point.

Abstract: 431,992. Control systems for consuming devices. BRITISH THOMSONHOUSTON CO., Ltd., Crown House, Aldwych, London. Nov. 16, 1934, No. 33051. Convention date, Nov. 16, 1933. [Class 38 (iv)] In arrangements in which a pair of gridcontrolled valves are used for controlling A.C. in a load circuit, a control potential from an external source is applied to the grid of only one of the valves, the other being normally maintained non-conductive and rendered conductive in response to current flow in the first valve. Fig. 1 shows an arrangement in which A.C. in a load circuit 11 coupled through a transformer 15 to an A.C. supply 10 is controlled by a pair of reversely connected valves 12, 13. When the valve 12 is rendered conductive by its control circuit 17, the valve 13 which is normally blocked by a bias battery 20 is also rendered conductive by impulses generated in a tertiary winding 19 on the transformer 15. In a modification, Fig. 2, the transformer 15 is dispensed with and the impulses necessary to overcome the effect of the bias battery 20 and render the valve 13 conductive when the valve 12 is rendered conductive by its external control circuit 17 are derived from a current transformer 22 in the load circuit.

Filed: 1945-12-10
Abstract: 624,358. Ammunition shoots. BRISTOL AEROPLANE CO., Ltd., and FONSECA, E. C. M. D. Dec. 10, 1945, No. 33375. [Class 92 (ii)] Relates to shoots comprising a plurality of flat, frame members so connected that each member can turn relatively to the others in its own plane, ammunition passing successively through an opening in each frame member. According to the invention shoots for conveying separated rounds of ammunition have arms projecting from each frame member in opposite directions to support the rounds, the frames being so held together that an arm projecting from one frame is opposite an arm projecting from the adjacent frame on the other side of the frame opening. Attached to a machine gun 12 at one end and a fixed guide 11 at the other end is a shoot 10 comprising relatively movable members 20 forming a channel of substantially constant depth for any elevation of the gun about an axis 16 which is the line of centre of the horizontal shoot. Each member 20 is substantially rectangular and comprises sides 17a and ends 18a forming part of the side walls 17 and end walls 18 of the shoot respectively. Each side 17a is formed of two parts 17b comprising a horizontal strip 17c from which extends a vertical strip 17d having an out-turned flange 17e, the two parts 17b being superposed to form 17a with the vertical strips 17d on opposite sides of 17c. The composite parts 17a are rigidly attached to the ends 18a as in Fig. 5. The flanges 17e form the bearing surfaces for the rounds of ammunition and the distance between the upper and lower flanges 17e is approximately equal to the diameter of the rounds. The forward end of a round is held in position by the forward upper flange of a member 20 and the forward lower flange 17e of the preceding member 20, while the cartridge case is held by the rear lower flange 17e of the said member 20 and the rear upper flange 17e of the said preceding member 20. Each end 18a of the members 20 carries a bracket 21 supporting a trunnion 22. A flexible spring-loaded cable 23 threaded through the trunnions 22 on each side of the shoot 10 is fixed at one end to the block 14 of the gun 10 and at the other end passes through a flange 13 at the end of the fixed guide 11 to a nipple 24 to hold the members 20 together. When the gun is elevated by an amount A, each member 20 is displaced in a vertical direction relatively to the preceding member 20 (the first member 20 being immovable with respect to the flange 13) so that the distance between co-operating flanges 17e is increased by an amount a which offsets the decrease in effective depth due to twisting of the shoot. To maintain the projectiles in parallel relationship the noses are provided with rings as described in Specification 624,355. The forward end wall of the shoot comprises spacer members 18a and 18<SP>1</SP>a along which the rings pass after being removed from the projectiles.
