Title: Improvements in apparatus for controlling ring spinning machines
IPC: D01H1/36
Filed: 1931-11-17
Abstract: 377,869. Speed-control mechanism for ring spinning- frames. TRIOU, A., 170, Rue de Paris, Montgeron, Seine-et- Oise, France. Nov. 17, 1931, No. 31872. Convention date, Feb. 20. [Class 120 (ii).] Mechanism for controlling the speed of ring spinning-frames, wherein two motions are combined, of which one is derived from the member producing the reciprocating motion of the ring rail and the other from the member producing the progressive motion, comprises a suitably shaped cam 1 loosely mounted on a shaft 2, which is operated in accordance with the reciprocating and progressive movements of the ring rail and drives the cam in one direction by means of a wheel 4 so that by means of a bowl 6 a lever 12, adjustably pivoted at 13 and carrying a bowl 16, is displaced and operates a cable 28 connected with a speed-changing device 30. The cable is connected to a lever 9 which is oscillated about a pivot constituted by the axle 7 of the bowl 6 by a rod 11 adjustably connected to an arm 21 on a shaft 22 reciprocating in accordance with the ring rail. As the bowl 6 is moved by the cam 1 in the slot of the lever 9, the amplitude of the movement imparted to the cable 28 by the lever is varied, and this, in conjunction with the movement imparted by the bowl 16, effects the necessary movement of the speedchanging device 30.

Inventor: BROWN JOHN KING
IPC: B24B33/02
Filed: 1954-11-04
Abstract: 807,852. Metal-cutting machine details. NICOL & ANDREW Ltd. Feb. 6,1956 [Nov. 4, 1954], No. 31881/54. Class 83 (3). [Also in Group XXIII] A metal-cutting, grinding or honing-machine comprises a bed, a carriage coupled to an operating-head movable along the bed, and a self-contained winch located at each end of the bed beyond the travel of the carriage, the winches being directly connected to the carriage. The machine comprises a carriage 2 on wheels 3 guided in the bed 1. The carriage 2 carries driving-means such as an electric motor coupled by a shaft 4 to a tool-head 5 for operating on work 6. Self-contained compressed-air-operated winches 7A, 7B at the ends of the bed 1 have their cables 8 coupled to the carriage 2. Inlet-valves 19, 20 for the winches 7A, 7B are operated alternately by a lever 15 actuated through arm 14 by a bar 9 mounted in stanchions 10 and carrying adjustable abutments 11, 12 engageable by a projecting arm 13 on the carriage 2; a lever 17 coupled to lever 15 by links 16, 16 operates exhaust-valves 21, 22. The carriage 2 is thus automatically reversed at the ends of its travel. A hand control lever 25 is connected by linkage 26 to the lever 15. Pressure-gauges 23, 24, calibrated in terms of thrust, indicate high spots on the work. The winches may be of the type in which the thrust of compressed air on a piston is communicated directly to the cable by means having a mechanical advantage less than unity; e.g. a cylinder and a piston movable therein may be coupled to the opposite sheaves of a pulley-block system.

IPC: A24C5/39
Filed: 1928-11-02
Abstract: 328,637. Grupe, W. F. Nov. 2, 1928. Cigarette-making machines.-In a continuousrod machine, a stream of tobacco is progressively reduced in width to a narrow stream which converges gradually on to a strip of paper moving in the same direction. In one form, Fig. 1, the tobacco is fed from a hopper 10 by a conveyer belt 11, a carded drum 13, a brushing roll 16, a picker roll 18 and a comb 19. The tobacco is directed on to a series of projectors 28 in a casing 40 by guide plates 20, 21, the plate 20 having a series of parallel or converging ribs or corrugations for producing a stream of tobacco of uniform or decreasing width. The projectors 28, Figs. 1 and 3, have curved vanes 30 for progressively narrowing the tobacco stream, each vane having a radial face and a streamlined following face. The tobacco stream is directed by a shoot 32, with longitudinal ribs 31, on to a flanged projector 36 which delivers the stream on to the moving paper web 33 fed through guide plates 35. The projector 36 has vanes 39 of herringbone form for further narrowing the tobacco stream, and a guide plate extends from the shoot 32 over the web 33. In a modification, the paper moves in a direction at right angles to that indicated in Fig. 1, the axis of the projector 36 being at right angles to the direction of movement of the web and the vanes of the projector being straight. In further forms, the projector 36 is omitted and the casing 40 of the projectors 28 terminates in an elongated tube lying substantially in the direction of movement of the paper web and preferably provided with internal longitudinal ribs.

Title: A lifting jack
IPC: B66F3/42
Filed: 1958-10-07
Abstract: 858,106. Hydraulic lifting-jacks. OLIVIER, H. Oct. 7, 1958 [Dec. 16, 1957], No. 31957/58. Class 78 (3). A cylinder A forming the lifting head of a jack is raised by reciprocation of a piston B in a stationary cylinder E surrounded by a reservoir F. During the down-stroke of handle I, the cylinder A and piston B are raised, valve C remains closed, and valve H opens to allow oil to flow from the reservoir F into cylinder E; whilst during the up-stroke, the piston B is lowered, valve H closes and oil flows from cylinder E into piston B thereby extending the cylinder A relative to the piston B by an amount equal to the stroke of the piston. Lowering is effected by opening a pedal-actuated valve O, thereby permitting oil to return from the piston to the reservoir.

Title: Fuel control system for gas turbine engine
IPC: F02C9/32
Filed: 1974-07-18
Abstract: 1501859 Gas turbine engine fuel systems LUCAS INDUSTRIES Ltd 23 May 1975 [18 July 1974] 31987/74 Heading F1G A fuel system for a gas turbine engine including a gas generator 11 and a separate work turbine 12 comprises a metering valve 15 actuated by a diaphragm 17 subjected, via an air potentiometer 19, 18, to a proportion of the difference between the outlet and inlet pressures P 2 , P 1  of the gas generator compressor and by a bellows 20 subjected to the inlet pressure. A throttle valve 21 downstream of the metering valve 15 and subjected to the pressure drop across the metering valve, acts to maintain the pressure drop constant at very low engine speeds, e.g., at start-up, and also during deceleration. Further throttle valves 23, 24 connected in series with each other and, in combination, connected in parallel with the throttle valve 21, are almost closed at these low speeds, and the throttle valve 23 is almost closed during deceleration, and in both of these circumstances they are ineffective to control the pressure drop across the metering valve 15. During steady-state operation, the throttle valve 24 is sufficiently wider open than the throttle valve 23 to ensure that the latter is effective to control the pressure drop across the metering valve 15. When the work turbine 12 is running below a predetermined speed, this control is in accordance with the relationship between the actual speed of the gas generator 11 as sensed by a governor valve 31 and the desired speed as set by a lever 27. Above the predetermined speed of the work turbine 12, a governor valve 36 driven by its open to reduce the controlling pressure applied by the governor valve 31 to the actuating diaphragm 26 of the throttle valve 23, thereby reducing the fuel flow. During acceleration, the throttle valve 23 is sufficiently wider open than the throttle valve 24 to ensure that the latter is effective to control the pressure drop across the metering valve 15. The throttle valve 24, which is controlled by the governor valve 31, controls the pressure drop in accordance with the speed of the gas generator 11. If the total pressure drop across the metering valve 15, the throttle valves 21, 23, 24 and a shut-off cock 39 becomes excessive, a spill valve 41 opens to spill fuel back to the inlet of the fuel pump 13.

Title: Improvements in the manufacture of peracetic acid
Inventor: BEESLEY STANLEY
IPC: C07C409/26
Filed: 1961-09-07
Abstract: Peracetic acid is produced by reacting acetaldehyde with oxygen in the vapour phase in the presence of at least 17.5% by weight, based on the acetaldehyde, of a solvent for peracetic acid. The process may be continuous by reacting the acetaldehyde and oxygen together, passing the reaction product to a fractionating column to which a solvent is fed, recovering the solution of peracetic acid at the bottom and recycling unreacted acetaldehyde vapour from the top of the column mixed with at least 17.5% of the solvent to the initial reaction zone.  The solvent is one which boils below 80 DEG C., e.g. acetone.  The temperature at the top of the column is preferably at least 25 DEG C., e.g. 35 DEG  to 45 DEG C. and is the temperature of the acetaldehyde/solvent mixture. Specifications 547,333 and 927,053 are referred to.

Filed: 1934-11-09
Abstract: 447,063. Frames and covers for manholes and the like. ELKINGTON, V., Dour Iron Foundry, Dover. Nov. 9, 1934, No. 32280. [Class 107] The frame 15 of a manhole cover 16 or the like is of channel section, open at the bottom, and is provided in its upper part with apertures 20 through which concrete can be injected to fill the hollow interior. The inner side wall of the channel is shaped to provide an inclined seating surface for the cover which surface may consist of two inclined faces 17, 19, and an intermediate substantially horizontal face 18 with rounded edges between adjacent faces. The cover is formed with similarly shaped faces 28, 29, 30 and thus may be readily removed from the frame. The cover is formed with main and subsidiary webs 24, 25 and apertures 26, and is adapted to receive fillings 52 of concrete or wood blocks. Main and subsidiary webs are also provided in the interior of the frame which is preferably formed of four separate sections each comprising a side and a corner. The corners may be rounded as shown or square, and adjacent sections are interconnected by bolts passing through their vertical end walls, a filling of hard white metal being added to key the joint. The frame may be cut away at each end to receive a casting which is riveted to the frame and which extends for a short distance beneath the cover. The projecting portion has a tapped hole for receiving a bolt which passes through the cover and locks it to the frame. In the case of large openings, the cover is made in sections, as shown in Fig. 11, the intermediate sections being each provided with a projecting edge 39 of a shape similar to the seating of the frame to provide a support for an adjacent section. Cross-bars may be provided for supporting the cover sections in cases where the frame is of considerable width. As shown in section in Fig. 13, such a cross-bar 40 is of similar construction to the frame members, being of inverted channel-section, having seating faces 17 ... 19, and having apertures 44 for receiving the concrete filling. The concrete is reinforced by rods 41 which support a stainless steel plate which closes the bottom. of the channel-bar 40. The bar is supported by a rolled-steel joist 45, the ends of which are carried in cast-iron housings 46 anchored to the roadway by rag-bolts. The cross-bar is bolted at its ends to the frame members, the joint being completed by a white metal filling. A stainless steel bolt passing through the ends of the cross-bar and bearing on the joist is employed to loosen and lift the cross-bar, to facilitate its removal, after which the joist also can be removed. In some cases the joist may be dispensed with. Specification 318,012, [Class 107], is referred to in the Provisional Specification.

Filed: 1969-06-26
Abstract: 1279847 Masted lift trucks DSO BALKANCAR 26 June 1969 [26 June 1968] 32457/69 Heading B8H The mast assembly of a lift truck is provided with a control system whereby the maximum height to which a load may be lifted is limited automatically in accordance with the weight of the load. As shown, the hydraulic pump motor circuit includes normally-closed switches 9-12 in parallel with normally-closed switches 5-8. The switches 9-12 are opened sequentially by cams as the lifting carriage rises, and the switches 5-8 are opened by pressure relays 1-4 which are connected to the hydraulic lift circuit and which are adjusted such that as the pressure in the circuit increases the switches 8-5 are opened in turn. Thus, when a load is lifted and if that load requires a pressure that will actuate relays 3, 4 and thereby open switches 7, 8, the load will rise to a height at which switch 11 is opened, at which point the electric circuit of the pump motor is opened, thereby halting the lifting carriage. In a modification, the lift ram is a multi-stage ram and the hydraulic relays are adjusted to correspond with the pressures at which the various ram stages operate, Fig. 1 (not shown). Circuits are also described for application to I.C. engined lift trucks, Figs. 2, 5 (not shown).
