IPC: F02B25/00
Filed: 1928-09-15
Abstract: 297,126. Dugelay, P. Sept. 16, 1927, [Convention date]. Void [Published under Sect. 91 of the Acts]. Flame igniters.-In an engine having terminal ports for exhaust and for the admission of scavenging air and a mechanically-actuated valve in each cylinder head for the admission of combustible mixture, rotary compressors, or fans supply the cylinder charges, ignition is effected by a flame from an adjoining cylinder and the mixture inlet valves are timed to vary the duration of admission and thus the final compression pressure. The cylinders are preferably disposed in radial formation, the six cylinders of such an engine being shown diagrammatically in Fig. 1. During the explosion periods pairs of cylinders communicate with one another through valves 13 - - 18 controlled by a common cam which is angularly adjustable to alter the timing of the valves. Each cylinder is provided with a sparking-plug 19 which may be housed in a pocket separated from its cylinder by a valve. The orifices of the chambers in which the sparking- plugs are housed are shown at 20 - - 25. If preferred, the engine may be provided with one sparking-plug only. An eight cylinder engine is described in which each explosion acts simultaneously upon two pistons, ignition being effected by a flame from an adjoining pair of cylinders. A single mixture admission valve serves each pair of cylinders.

Abstract: 1,059,961. Helicopters. RIPPER ROBOTS Ltd. Oct. 8, 1963 [July 10, 1962], No. 26543/62. Heading B7W. [Also in Division G3] A helicopter utilizing a rigid lifting rotor as the sole means of horizontal propulsion has a linear accelerometer so mounted in it as to measure horizontal airspeed. In Fig. 1, the body of a drone helicopter used for crop spraying is supported by a framework 12 on which are mounted two engine-driven lifting rotors 14, 16 of the non-flap, non-see-saw type, and two transverse control surface flaps 22, 24 in the rotor slip streams. Electrical signals from a transverse accelerometer (not shown) on axis YY are amplified to control the pitches of the two rotors in opposite senses and maintain any desired sideways movement. Amplified signals from an altimeter (not shown) control the pitches of the two rotors in the same sense to maintain any desired altitude or vertical movement. Electrical signals from a longitudinal accelerometer (not shown) on axis XX are amplified to control the deflections of control surfaces 22, 24 in the same sense to maintain any desired fore-and-aft movement. Amplified signals from a compass, which may be of the integrating type, or a radio guidance system, control the deflections of control surfaces 22, 24 in opposite senses to maintain any desired yaw attitude. Electrical signals dependent on the speed of the engines are utilized to maintain engine speeds at desired values. Signals representative of the desired values of the various quantities are derived manually and may be transmitted by radio from the ground. Automatic control of the helicopter by controlling the speeds of the two rotors or their relative attitude, and the use of coaxial twin rotors, is referred to. Control of the helicopter about all three axes by means of flaps is also referred to.

Title: Reversing device for pressure-lubrication equipment
IPC: F16N25/02
Filed: 1958-08-21
Abstract: 894,404. Valves. SATZGER, E. Aug. 21, 1958 [Aug. 22, 1957], No.. 26883/58. Class 135. A reversing lubricant dosing device with two outlets 7, 8 which are connected alternately with a source of pressurized lubricant 6 and with a pressure-relief line 9, has two consecutivelyactuated leading and lagging control pistons 1, 2, whose piston ends are acted upon by the infeed pressure or by the discharge pressure, and of which the piston 1 controls the connections of the outlets with the source of pressure and the supply line, whilst the piston 2 effects the interconnections of control ducts for the subsequent reversal. The reversing process is initiated by the opening of a maximum-pressure relief-valve 27 that controls the connection of one of the chambers 36, 37 of piston 1 with the pressurerelief line. As shown, inlet pressure is continuously led to the space 15 between the end lands of the piston 1 by a passage 10. Depending on the position of the piston 1 relative to the piston 2, the space 15 is in communication with one of the outlets 7, 8 through one of two passages 14 or 19 in the piston 2. Also, one of the piston chambers 36, 37 is in communication with one of two passages leading via slot 20, or 30 to a chamber 25 which opens to the relief line 9 through passage 26. In operation, after the dosing appliance connected to the outlet 7 has discharged, the infeed pressure rises and causes relief valve 27 to open to enable the infeed pressure to move the piston 1 to its other end position so that it then supplies lubricant to the outlet 8 ; the relief valve closes with the ensuing pressure drop. The outlet 7 is then in communication with the relief line 9 via passages 14, 37, 36, 29, 31 and due to the pressure difference across the piston 2 the latter moves to an upper position where the reverse cycle takes place. A non-return valve 34 is provided in the line 9 and a relief valve 40 in the passage 29. During transit the two piston valves are held in functional relationship by a spring-loaded ball.

Title: Winding head for winding weft threads on to shuttles
IPC: D03D47/26
Filed: 1971-04-19
Abstract: 1327683 Winding precise lengths of thread; shuttleless loom VYZKUMNY USTAV BAVLNARSKY 19 April 1971 [28 April 1970] 27253/71 Headings D1E and DIF  The invention is concerned with apparatus for winding a precise length of weft thread onto a bobbon within a shuttle.  A bobbin spindle 1 carries a brake-wheel 32 that can be held by jaws 52 against rotation derived from a slipping friction clutch (2), Fig. 1 (not shown), until such time as the jaws 52 are moved apart by upward movement of a lever 4. When this happens the friction clutch (2) drives the spindle 1 until the lever 4 is lowered to its original setting. The extct time that the lever 4 is raised is determined by a counting gear 9.  To start a winding operation a releasing member 19 is swung inwardly in Fig. 2 to cause a rod 20 to move a box plate 21 to the right against a compression spring 30. This movement of the box plate 21 causes a cam surface (57) thereon to displace a lever 22 in a manner releasing a friction wheel 8 from friction engagement with the counting gear 9. The friction wheel 8 is then turned anti-clockwise by a spiral spring 12 until a stop pin 7 on the wheel 8 strikes against a finger 13 on a regulating lever 15.  The movement of the pin 7 away from the lever 4 will allow the lever 4 to raise under the action of spring 6 when permitted to do so by clock-wise movement of member 19. This upward movement of the lever 4 releases the jaws 52 from the brake-wheel 32 and winding of the bobbin on the spindle 1 commences. Lever 4 can only move upwards, however, when the lever 19 has swung back to the setting shown since until this happens a blocking shoulder 18 on the releasing member 19 will be in engagement with the end 17 of the lever 4.  When the releasing member 19 has moved back to the setting shown the box plate 21 will also have moved back and its cam surface (57) will no longer act on the lever 22. As a result the friction wheel 8 now drives the counting gear 9 clockwise until the stop pin 7 again contacts the lever 4 to move it downwardly and so allow the jaws 52 to grip the brake-wheel 32. On the spindle 1 in a gear 33 that meshes with gear 11 of a double-gear 11, 34. Gear 34 meshes with counting gear 9.  The counting mechanism can be adjusted over a range of settings to allow the length of weft thread wound to be varied.

Title: Improvements in filling heads for bottle-filling machines
Inventor: FOX DOUGLAS PERCY SHOOL BRED
IPC: B67C3/26
Filed: 1954-09-24
Abstract: 792,262. Bottling. FOX & CO., Ltd., D. Aug. 18, 1955 [Sept. 24, 1954], No. 27730/54. Class 125(2). In rotating table counterpressure bottling machines having filling tubes 26 the lower ends of which are closed by pear valves 27 closed by springs 30 and opened by fluid pressure acting on a piston 29, a single rotatable plug cock 14 actuated step by step by stationary trips supplies counterpressure and fluid pressure for actuating pistons 29 to each pair of filling tubes 26, a check valve 21 being provided for cutting off the counterpressure if a bottle should burst, but being prevented from closing during the application of counterpressure. As shown, extensions 102, 103 of a central body 10 are each provided with a depending filling tube 26 and the body 10 contains a vertical bore 11 containing a vertical plug cock 14 the shaft of which is extended upwardly and the end thereof is connected with a certain amount of lost motion to a star wheel 151 so that shock occurring when the trips actuate the star wheel is largely absorbed. Counterpressure is supplied through passages 19, 17 to the space 11 and bottling liquid through passages 20, 18 and a pair of passages 36 to chambers 24 communicating with the filling tubes 26. In operation, the parts are initially in a first stage in which the pear valves 27 are closed by springs 30 and the ports of cock 14 are also closed ; during this stage each bottle is raised to contact and raise a guide bell 32, a gasket 322 on which seats an annulus 253 fixed to the bottom of extensions 102, 103. The cock 14 is then rotated by the first trip to the second stage in which counterpressure can flow through passages 37 in the cock and passages 33, 34, 341 to the bottle ; during this stage the check valve 21 in the counterpressure supply is held from its seat by a projection 143 on the cock. The second trip then rotates the cock to the third stage in which the passages 37 still connect space 111 to passages 33 and also connect the space through passages 31 to space 221 above the piston 29 so that the counterpressure forces down the piston and opens valve 27 to allow liquid to flow into the bottle. During this stage, check valve 21 can move to its seat should a bottle burst and the passages are vented to atmosphere through the burst bottle so allowing spring 30 to close valve 27 ; also during this stage displaced gas flows from the bottle in reverse direction through passages 341, 34 and 33. The third trip then moves cock 14 to the fourth stage in which passages 38, 39, 40 therein connect passages 31, 33 to atmosphere so that spring 30 closes liquid valve 27 and the bottle head space is snifted. The cock is then turned to its initial position and the filled bottles are lowered. According to the Provisional Specification, the plug cock controls a single filling tube assembly only.
