Title: Improvements in or relating to hydraulic pumps
IPC: F04B49/22
Filed: 1957-03-15
Abstract: 858,901. Reciprocating pumps. BOCKUMER GESELLSCHAFT FUR GRUBENAUSBAU UND TECHNIK. March 15,1957 [March 19, 1956], No. 8570/57. Class 102(1). A reciprocating pump comprises at least one piston and cylinder relatively displaceable by a rotary drive motor, the inlet to each cylinder being provided with a non-return valve and a throttle the size of which varies in direct dependence on the torque required to be exerted by the motor to effect the relative displacement. The pump shown in Fig. 4 comprises four radially arranged cylinders 1 driven by an electric motor 43 in which a rotatably adjustable throttle plate 38 is provided with openings 40 controlling the inlets to such cylinder. The plate 38 is connected through a linkage 41 to a bed plate 42 secured to the stator of the motor and supported for pivoting about 44 in a trestle 45. When the torque increases, due to a rise in pressure in the delivery line, the reaction of the torque rotates the stator and bed plate in the direction d against a spring force 47 to reduce the throttle opening. The opening 40 may be pear-drop shaped or circular so that the throttle opening may be varied from a maximum to 5% of this value. In a modified form the throttle plate is connected by linkage directly to the stator which also carries a counter-weight in the form of a loose fitting piston in a cylinder filled with oil.

Title: Improvements in or relating to machines for the scutching or decorticating of flax, hemp and analogous fibres
IPC: D01B1/30
Filed: 1930-03-18
Abstract: 343,351. Scutching flax, hemp, &c. ROBEY & CO., Ltd., Globe Works, and McGAUGHEY, R. S., 2, Bernard Street, both in Lincoln. March 18, 1930, No. 8599. [Class 120 (i).] In a machine for scutching flax &c., the stricks are scutched along one side only during one operation by being carried by a travelling holder axially along a single cylindrical beater drum and by the tails of the stricks being held in contact with the beater bars by an air blast provided independently of the beater drums. The bars scutch one side only of the end of the strick, the other side being subsequently presented to a second beater drum prior to the other ends of the stricks being similarly treated. Flax &c. stricks fed by a band 1 are gripped at one end between a balata belt 3, passing around grooved pulleys 2, 6 and jockey pulleys 7, 8a, 9, 8, and a rubber belt 4 which embraces the lower parts of the pulleys 2, 6 and is guided by pulleys 8 .. 12, the flanges on the pulley 2 co-operating with the belts to grip the flax 5, Fig. 6. The belts 3, 4 draw down the stricks and present them to a rotary beater 13, comprising wooden bars 28, Fig. 4, secured to spiders 29, while a long fan 14 holds their tails on the beater which scutches the underside thereof. The stricks are withdrawn from the beater as the belts rise to pass over the pulley 8 and are then presented similarly to a second beater 15, offset from the beater 13, and rotating in the opposite direction thereto which co-operates with a fan 16 to scutch the other side of the end of the stricks already scutched. The scutched ends of the stricks hang down until a guide 17 raises them as the belts approach the pulleys 8a, 10. Pulleys 18, 36 similar to the pulleys 2, 6 but offset from them, carry co-operating belts 19 which grip the stricks at the ends which have been scutched and permit the untreated ends to be scutched on both sides by beaters 20, 21 aided by fans 30, 31 before the completely scutched flax is delivered from the machine. The beaters 20, 21 rotate in opposite directions and the beater 20 is mounted on the same shaft as the beater 15.

Title: An improved motor-protection switch with quick release
IPC: H01H71/68
Filed: 1946-03-20
Abstract: 609,686. Automatic circuit-breakers. LANDIS & GYR SOC., ANON. March 20, 1946, No. 8689. Convention date, March 29, 1945. Addition to 605,418. [Class 38 (v)] The invention of the parent Specification is modified in that the circuit of the switch magnet is controlled by a cut-out relay which in the closed position of the protective switch is in turn latched with the carrier for the combined movable contact and latch members, so that the closure of the protective switch when the switch magnet is de-energized, is maintained by the cut-out relay. The moving contact carrier 1 and armature 2 are independently pivoted at 4 and have projections 54 which inter-engage when the magnet 3 is energized to close the switch, in which position a latch 63 on the carrier 1 engages the latch arm 61 of a normally-energized relay 56, 57, and at the same time opens an auxiliary switch contact 34 to de-energize the closing electromagnet 3, whereupon the armature 2 is returned to the off position by spring 2a. Another auxiliary switch 59 opened by the lever 22 and pin 10a on contact 8 de-energizes the latch relay 56 after a quick-release of one of the phases, so releasing the carrier 1 and opening all the phases, and also the contact 33 of the auxiliary switch to prevent an attempt to reclose before the released contact is reset. The resetting knob 28 operates the latter through the lever 22 and pin 10a and also permits spring 40 to latch the carrier 1 during resetting; it also allows switch 59 to reclose and re-energize relay 56 to reset the latch 61 and prepare for reclosure by press-button 55.

Title: Improvements in or relating to carbon coated resistors
IPC: H01B1/24
Filed: 1940-05-15
Abstract: 541,241. Resistances. ROSENTHAL, E., and SCHAEFER, E. May 15, 1940, No. 8700. [Class 37] Carbon-coated resistors, of the kind comprising porcelain rods or other insulating members coated with a thin film of crystalline carbon deposited thereon by the dissociation of hydrocarbon gas at high temperature in a vacuum 'furnace, are manufactured in such a way that uniformity of resistance is obtained in each batch from the furnace. The latter comprises a porcelain tub 1 which is heated to 700‹ C. by a coil 2, the turns of which are closer spaced at the ends, and exhausted by a pump 13 and then charged with the hydrocarbon gas from a liquid-container 12. The latter comprises a bulbous part 14 and a graduated neck 15 leading to a tapered part 16 and flange 17 for fusing to a tube of small and large diameter, respectively. The rate of deposition can be controlled by the pump and the flow arrested when the right resistance is obtained, and the container can be changed for one of larger or smaller diameter where a greater or less volume of liquid is required. The flow of gas, and hence the duration of the coating operation, can be varied by choice of one of a range of constricted tubes, the constrictions 20 of which are of different sizes. These tubes have ends 21, 22 analogous to those 16, 17 of the containers and can be separated at the fused parts to effect a substitution. Fig. 2 (not shown) illustrates how, by using a pair of cocks between the furnace and the pump and container, the gas may be caused to reverse its direction of flow in the furnace. The Specification refers also to cooling the liquid container for controlling the rate of vaporization, and to grinding helical grooves in the completed rods for obtaining different resistance values. Alternatively or additionally, the coated rods may be immersed in quartz sand in a grinding cylinder which is rotated for a period of time depending on the resistance required.
