Title: Improvements in or relating to electrical relays or the like apparatus
IPC: H01H51/22
Filed: 1927-03-22
Abstract: 293,082. General Electric Co., Ltd., Angold, A. E., and Wilson, W. March 22,1927. Electromagnetic current and pressure meters. -Electric relays and indicating instruments are constructed with pivotally mounted moving parts arranged and. interconnected in such a manner that when a body with which they are associated is subjected to rotary motion such as oscillation the inertia force of one moving part acts differentially with respect to the inertia force of at least one other moving part, and said differentiallv acting forces counterbalance, whereby the motion is ineffective to produce movement of the. moving parts relatively to the body. The moving parts of a leakage relay or indicator, as shown in Figs. 1 and 2 consist of two frames 13, 14 pivoted on knife-edge trunnions 3U supported by springs 31 the inner ends 37, 38 of the frames being interconnected by a link 26. Each of the frames 13, 14 carries at its inner side, a pair of permanent magnets 15, 16 and 17, 18 counterbalanced by weights 23 and arranged at opposite sides of fixed bus-bars 1, 2 carrying currents in similar directions the polarities of the magnets being arranged in the manner described in Specification 293,083 so that when the currents in busbars 1, 2 are unequal the frames are rotated in opposite senses to operate relay contacts or to give a suitable indication of the unbalance. Tf, however the relay &c. is mounted in a location, e.g. on a railway train motor vehicle or aeroplane in which it is subjected to external movement such as oscillatory rotary movement the forces exerted on the two frames 13, 14 due to their inertia are equal and opposite and as their adjacent ends are linked together in the manner described such motion will be ineffective to produce motion of the frames relatively to the bus-bars.

Title: Improvements in or relating to the manufacture of brushes
IPC: A46B3/04
Filed: 1941-06-26
Abstract: 550,229. Moulding brushes. HOOVER, Ltd. June 26, 1941, No. 8032. Convention date, Aug. 29, 1940. [Class 87 (ii)] [Also in Group XXIII] In making a brush comprised of bristles of a synthetic organic compound, particularly of nylon, moulded and fused into a thermoplastic back, particularly one containing polymerized vinyl acetate and polymerized vinyl chloride, the bristles are fed from a hopper 25, Fig. 4, by a notch 28 in a reciprocating separator 26, 27 to a position over a loading core 16, into which they are forced by a plunger 30 so that their looped ends project below the base of the core. This loaded core is inserted in the movable member 15, Fig. 2, of a two part core with the bristles projecting into a cavity 18 in a stationary core member 14, and the thermoplastic material is forced into this cavity through a feeding orifice 19 from an injection nozzle 20 of a cylinder 21, into the rear portion of which the material is fed in pellet form 24 from a hopper 22. The forward end of the cylinder is provided with a heating chamber 23. Cooling fluid is circulated through passages 17 in the mould, causing the material to set rapidly around the ends of the bristles. The mould is then opened, the brush removed and the flash or sprue at the back of the brush cut off. In an alternative method, a number of filaments of the synthetic organic compound are brought together to form a continuous strand which may be wound on a drum, and the end of each strand is fused so that the strands can be readily threaded into the seats in the movable mould member without using a loading core. The operation then proceeds as before, the mould members being finally separated a sufficient distance to allow the bristles to be cut off to form the brush, leaving a small amount of the strands projecting from the mould member ready for the next operation.

Title: Method of and machine for bundling sticks
IPC: B65B27/10
Filed: 1942-06-15
Abstract: 558,154. Packing. JACKSON & CROCKATT, Ltd.. J. G.; and GAIR. D. June 15, 1942. No. 8131. [Class 94 (i)] A method of forming sticks into wrapped bundles consists in loosely bundling a supply of sticks moving the bundle into chamber where it is rolled into a compact cylindrical form, and introducing adhesive wrapping material into the chamber so that the bundle is wrapped during the rolling operation. The method is intended particularly for use in bundling sticks of cordite to form propellant charges for artillery. The sticks may be bundled about a central core which may consist of shorter sticks or of an additional component. The machine comprises a hopper 11, Figs. 1 and 2. into which a charge of cordite sticks is inserted when permitted by a guard 12 that is periodically drawn clear of the hopper. The hopper comprises an outer funnel for the larger sticks A, and an inner funnel into which any shorter sticks B are inserted. The sticks rest on closure jaws 13 which are opened periodically to allow the sticks to pass into a receptacle 10 divided into an outer cylinder 16, Fig. 4, and an inner cylinder 17 that receive the .sticks A and B respectively. The receptacle 10 is mounted on trunnions, and when charged it is turned through a right angle to allow the sticks to be moved longitudinally by plungers 18, 19 through conical guides 37, 38 into a chamber formed by a dependent loop 28, Figs, 2 and 4, of an endless band 23. The band passes over rollers 24, 25, 26, 27, and when the sticks have arrived in the loop 28, the roller 26 is moved to tighten the loop. Simultaneously, a rotating roller 30 is moved into contact with the band, presses it into contact with the roller 24, and drives it by friction. The band rolls the sticks into a compact cylinder, and when this has taken place, strips C of adhesive material are drawn from rolls D by reciprocating grippers 43, and fed into the rolling-chamber and rolled around the sticks. suitable lengths being cut off by a knife 45. When the wrapping-operation is completed, the belt is slackened again, and the completed bundle is pushed by the succeeding bundle on to a delivery shoot 47. In order to prevent adhesive strips being fed to the rolling-chamber if a charge of sticks is not supplied to the machine, a feeder is provided which is thrust periodically into the chamber 10. If a charge of sticks is not present, the feeler moves a stop into the path of the grippers 43.

Title: Railway vehicle braking systems
IPC: B61H11/00
Filed: 1971-03-30
Abstract: 1362269 Increasing adhesion of wheels on rails GIRLING Ltd 28 March 1972 [30 March 1971] 8166/71 Heading B7J A railway braking system comprises wiper means arranged to be applied to the tyre of a vehicle wheel or the rail on which it runs for increasing the coefficient of friction between the rail and the wheel and being operable to wipe the tyre or rail without imposing any substantial braking effort even when fully applied, and means responsive to actuation, either directly or indirectly, of the wheel brake or a deceleration responsive device to apply the wiper means. In the preferred form of the invention the system comprises a pneumatic actuator 4 for a pair of caliper levers 7 carrying brake shoes 8 disposed on opposite sides of a wheel. The wiper means is an auxiliary shoe 6 movable towards and away from the wheel tyre by an auxiliary pneumatic actuator 5. The shoe 6 has a surface adapted to increase the coefficient of friction of the tyre by cleaning or drying it. It may have a pad of rapidly wearing adherent abrasive material. A brake fluid pressure line P is connected to the actuator 4 through a normally-open electropneumatic pressure reducer valve 2 operable by a skid sensor 1 which produces an electrical output on a predetermined deceleration of the wheel to operate the valve 2. The auxiliary actuator 5 is connected to the fluid pressure supply by a branch line P1 via a pilot-operated control valve 3. The valve 3 has two chambers divided by a diaphragm F urged by a spring E and carrying valves H and J. The chamber housing the spring E and valve J is connected to the output side of the valve 2 whilst the other chamber is in the line P<SP>1</SP> and has air inlet A and an outlet C provided with a bleed passage G. Under normal operation both chambers are at the same pressure and the spring E shuts the valve H and opens the valve J. When an incipient skid condition is sensed by the sensor 1 the pressure in the spring chamber of the valve 3 is reduced and thus the diaphragm is moved under full pressure against the spring E to close the valve J and open the valve H and cause the wiper 6 to operate. The wiper is applied until the supply pressure through P is cut-off or reduced such that the spring E can reclose the valve H. Residual excess pressure in the actuator 5 is relieved through passage G.

Title: Improved device for controlling the flow of a fluid
IPC: G05D23/12
Filed: 1946-03-15
Abstract: 633,690. Diaphragm valves. A.S.W. APPARATENFABRIEK N.V. March 15, 1946, No. 8175. Convention date, June 7, 1940. [Class 135] A valve actuated, e.g., by a thermostat, pressurestat, or hygrostat &c. is characterized by a body disposed between a pair of interconnected diaphragms so that the diaphragms are capable of deflection in either direction, whereby on one of said diaphragms being moved into contact with a side face of the body the other diaphragm is moved away from the other side face, each of said side faces within the area with which the corresponding diaphragm comes into contact being provided with supply and discharge ports. As applied to the control of gas to the burner of an absorption refrigerating machine the valve comprises a casing 9, housing a disc-like body 6 provided with upstanding rims 7, 8 on which rest celluloid diaphragms 4,5 connected together by a stud 15 and nuts 17, 18 with a spacer 16 therebetween. The stud is in contact on one side with a pin 19 of the bellows 3 of a hermetically-sealed thermostat, having a bulb 1 containing a volatile liquid and located inside the refrigerator, and on its other side with a loading-spring 20 adjustable by the rotation of a cam 31. The body and the diaphragms are secured between a ledge 10 in the casing and a locking-ring 11. The disc 6 is formed with an inlet duct 21 having ports 25, 26 leading therefrom to the spaces between the disc and the diaphragms, and an outlet duct 22 communicating with these spaces via the space 22b, around the spacer 16. When the temperature in the refrigerator rises above its desired value, the thermostat bellows expands and moves the diaphragms downwards to close the port 25 and permit an increased flow of gas through the port 26 to the burner. When the temperature falls, the port 26 is closed and sufficient gas flows through the port 25 to maintain the burner pilot light. In a modification, the rims 7, 8 are dispensed with and the diaphragms are arranged to curve outwards when the ports are open. The valve may be used to control the supply of gas to a geyser &c., in which case the port 25 is made larger than the port 26. Specification 347,530 is referred to.

Title: Improvements in submarine vessels
IPC: B63G8/00
Filed: 1919-04-03
Abstract: 140,603. Lieske, r. J. April 3, 1919. Submarine vessels. -. Submarine vessels are adapted to receive auxiliary submarines on slips at the stern of the vessel and just abaft the conning- tower. The auxiliary submarines are received and interlocked with the main vessel longitudinally. When housed, the exteriors of the auxiliaries conform to the shape of the general exterior of the parent vessel, reducing resistance to propulsion. The auxiliary submarines are provided at their forward ends with tubes 9 fitting a corresponding tube 10 in the wall of the main submarine. When disengaged, the tubes 9 act as forward ends to torpedo tubes 30 sliding on ways 32. The block 12 may close the aperture in the main submarine prior to disengagement. Motors 17 operate nuts 21 screwed on shafts to draw the .auxiliaries into final locked position, the end of the shaft 15 engaging the hook 16 on the main vessel. Screws 40, 41 arranged transversely and vertically permit slight adjustments of the main vessel to facilitate entrance of the auxiliaries into the slips. Additional locking-means comprise a series of lugs on the slips engaging similar lugs on the auxiliaries retaining them against vertical movement. Rack teeth may also be fitted to the keels of the auxiliaries in gear with wheels on the slips operated from within the main vessel. The relative disposition of the two auxiliaries is such that the after auxiliary can float upwards, when released, free of the other auxiliary. The parent vessel may be an ordinary surface vessel instead of a submarine vessel.

Title: Improvements relating to sheet folding, interleaving and like machines
IPC: B42C7/00
Filed: 1939-03-16
Abstract: 526,442. Photo-electric control of sheet-feeding machines. DICKINSON, S. March 16, 1939, No. 8399. [Class 40 (iii)] In sheet-folding, interleaving, and like machines, the feeding of backs or interleaves is controlled by a photo-electric apparatus which counts the sheets fed to the folding or stacking position and allows a back or interleaf to be fed after a predetermined number of sheets have been fed. As shown, the sheets are fed by belts a, b, c, Fig. 1, to the stack d against a brush e, and on their way are counted by a photo electric device h, i as in Specification 497,105. When a given number of sheets has been stacked, the photoelectric device causes a motor j to drive a cam shaft k through one complete revolution. This shaft carries four cams. One cam controls suction to cups m, Fig. 2, and another cam serves to lift arms s carrying these cups whereby a back is lifted from a pile f. A third cam advances the shaft r of the arms s to feed the lifter back to tapes c. And the fourth cam lifts a roller 2 to receive the back and drops it again to help the feed of the tapes c, which transfer the back to the stack d. Jets m<SP>1</SP> help to separate the backs on the pile f. After a given number of sheets has been fed on a back, the stack d is folded and expelled, a fresh back fed and a fresh set of sheets stacked on and again folded. In a modification, a motor running continuously may be used, in which case, the photo-electric device controls a clutch between the motor and the cam shaft.
