Patent GB-202367-A (GB)
Abstract: 202,367. Munro, H. May 5, 1922. Shaft couplings; sccuring toothed wheels on shafts.-In flexible couplings for connecting aligned shafts or concentric shafts on the outer of which is mounted a gear-wheel, one shaft carries curved concentric cylinders with which co-operate rams on the other shaft, the rams being forced out against normal load pressure by fluid, and their movement being limited by stop means or by the fluid supply being cut off. A driving or driven shaft 1, Figs. 1 and 2, carries pairs of curved rams 5, 5<a> working in cylinders 4, 4a carried by the shaft 2 and respectively operative for forward and reverse rotation. As shown in Fig. 3, the hollow shaft 1, carrying a gear-wheel 25, drives by a toothed coupling allowing longitudinal freedom a floating member 27, which carries the rams and is supported on the shaft 2 or on a flange 33 or on both parts. High-pressure fluid is supplied to the cylinders 4 through a pipe 10, Fig. 4, check valve 13, and pipes 6, and lowpressure fluid to the cylinders 4a by a pipe 11, check valve 13<a>, and pipes 7; communication with the shaft 2 is effected through coupling-pieces 30. Outward motion of the rams ceases by leakage at the mouth of the cylinders balancing the supply, by automatic stoppage of the supply pump, by actuation of a valve, or by the rams encountering a stop. On the occurrence of an overload, fluid is discharged through a relief valve 12, Fig. 4, and, if the overload persists, the discharge is throttled in the cylinders by one of the methods shown in Fig. 1 or alternatively or additionally by external means. The internal throttling-means may comprise fitting portions 39, 40 of reduced diameter, a tapering exhaust port 16 co-operating with a non-return valve 32 in the inlet passage 17, or a supplementary piston 36 co-operating with a cavity 35 in the main ram, there being a non- return valve 38 in the inlet passage 37. The external valve system is automatically actuated by a link 8, lever 24, and a grooved collar 22 driven by the shaft 1 and engaging a helical groove 23 on the driven member; it comprises a changeover valve 9 and either a slide-valve 15 capable of rising from its seat to allow flow to the cylinders or a rotary throttle 31 in a branch pipe. To provide for reversal, the system may be duplicated, as shown at 31<a>, 12<a>, or a change-over valve may be arranged between these valves and the cylinders. During overload, the appropriate check valve 13 or 13a is held open by a connection from the link 8 or otherwise, to allow reverse flow along the pipe 6 or 7. According to the Provisional Specification, the cylinders may be carried by the floating member 27; the supply pump may be mounted on the shafting and may have a controlled variable delivery.

Abstract: 293,839. Regnauld de Bellescize, H. J. J. M. de. July 13, 1927, [Convention date]. Thermionic heterodyne receivers. - A four - electrode valve has its inner grid 6 connected to the local oscillator, its outer grid 7 being connected to the wavereceiving circuit and through a variable coupling 11 - - 13 to the local oscillator The tuned circuit 2 of the local oscillator has the points 9, 10 at opposite potentials connected to fixed condenser plates 12, 13, the movable vane 11 being connected to the outer grid 7 to supply oscillations of either phase thereto. A two-fold heterodyne effect is obtained due (1) to the superposition of the two waves in the circuit of the grid 7 and (2) to the application of one of the waves to each grid 6, 7. If the local wave is shorter than the incoming wave, the two effects are additive when the plate 11 is coupled to the plate 13. and tend to neutralize each other when the plates 11, 12 are coupled. With the local wave longer than the incoming wave, the reverse conditions obtain. In a modification, (Fig. 2, not shown) the local wave is generated by the four-electrode valve, the tuned circuit 2 being connected between the plate 8 and the inner grid 6.

Abstract: 1,066,983. Doffing and donning. SPETSIALJNOE KONSTRUKTORSKOE BJURO TEXTILJNOI PROMYSHLENNOSTI. May 15, 1964. No. 204026/64. Heading D1D. In a spinning or twisting machine doffing and donning device comprising a carriage 1 split into an upper section (Fig. 2) and a lower section (Fig. 4), the upper section may be lifted relative to the lower section after a doffing and donning run so as to suspend drive to the doffing and donning elements and allow the carriage to be moved by its rope drive 9 back to its starting position. As shown the lower carriage section is mounted on rails 2, 3 to be movable along the frame by a rope drive 109, 110. The upper section of the carriage is supported on rods 87, 95 which are mounted in the lower section and are vertically moveable by rotation of a hand operated wheel 93. When a doffing and donning run begins the upper portion is arranged to be in its lowered position in which clutch elements 75 which are driven from gears engaging a rack on the rail 2, are in driving contact with clutch elements 55, 56 in the upper section of the carriage so that drive is transmitted to shafts 53 and 19 which drive various doffing and donning devices on the upper section. Doffing. Doffing is effected by a forked wedge 7, the two arms of which pass either side of the spindles to lift the full cops into guides 69, the thread being severed by cutting blades 49, 50 operated by a shaft 53 on which the clutch parts 55, 56 are mounted. The cops are forced (by subsequently removed cops) into a chute 68 whence they pass to a conveyer 6 which carries them away. The wedge 7 which has a thread deflecting element 9 thereon is mounted on bars 12 which are laterally slidable in guides 13 so that at the end of a doffing run the wedge can be slid outwardly from the frame and be kept clear of the spindles in the reverse run of the carriage. Donning. Empty cop tubes are placed in a hopper 34 whence they pass via a rotating feed drum 28, driven from the shaft 19, to a magazine 35 in which they are held in an inclined position by claws 41, 42. The lower end of the tube in the magazine engages an empty spindle and slides under gravity onto the spindle, an oscillating, resiliently mounted plate 58 being arranged to strike the tube a downward blow to secure it on the spindle. Sprung hinged doors 35, 46 are provided on the hopper'and on the magazine to prevent jamming of the tubes.

Abstract: 1,212,752. Anti-sidetone circuit. INTERNATIONAL STANDARD ELECTRIC CORP. 2 May, 1968 [10 May, 1967], No. 20879/68. Heading H4R. An anti-sidetone circuit for a telephone subset comprises a bridge circuit including oppositely directed amplifiers 57 and 58 in opposite arms with the two wire line 52 connected across one diagonal of the bridge at points 63 and 64 and with a differential amplifier 56 connected to receive the signal across the other diagonal and apply it to the receiver 51. The microphone 50 is connected via a phase splitter 55 to feed signals of opposite polarity to amplifiers 57 and 58, amplifier 57 being a grounded emitter amplifier, providing a further 180 degree phaseshift to the signal applied to point 61 of the bridge, and amplifier 58 being an emitter follower providing no further phase shift to the signal applied to point 62, so that signals of identical phase and similar amplitude appear across the differential amplifier from the microphone, providing only the required small sidetone, while appreciable signal is fed to the line 52. Amplifiers 57 and 58 present appreciable impedance to signals on the line 52 which are therefore applied, via capacitor 70 and capacitor 71 and relatively low value resistor 59, across the differential amplifier input, to be applied to the receiver 51.

Abstract: 703,944. Injection-moulding machines. ECKERT & ZIEGLER GES. Sept. 6, 1951 [Sept. 7, 1950], No. 21060/51. Class 87 (2) In a machine in which the hydraulic mouldclosing piston 2 is integrally connected to the movable mould part 4 and is under low pressure during the initial part of the mould closing stroke and high pressure when the mould is closed, the additional pressure to keep the mould closed is derived from an intensifier 10 by way of a hydraulic column 7, the intensifier being acted upon by a pressure cushion which is resilient, e.g. pnuematic, and is independent of the hydraulic source of pressure. As shown, the pressure cushion is a body of compressed air above the piston 25 of the intensifier. Water under pressure is supplied at 18 and leaves at 15. In operation, to close the mould, valves 23 and 19 are opened, whereupon pressure through 23, 20 and 7 forces (differential) piston 2 to the right to close the mould and simultaneously pressure passes through 19 and 13 to raise piston 25. Then valves 23 and 19 are closed and valve 14 is opened, whereupon the pressure is released from space 12 and piston 25 descends to exert a high pressure on hydraulic column 7 via piston rod 9. To open the mould, valve 14 is closed and valves 19 and 21 opened.
