IPC: D03D49/06
Filed: 1919-11-03
Abstract: 162,695. Brigg, T. H. Nov. 3, 1919. Letting-off warps.-In let-off motions for maintaining a uniform tension on the warps, a feeler mechanism is adapted to control automatically the location of the operating weight-carrier on a balance lever, the operation of the feeler mechanism being such that the sum of the moments about the centre of the warp beam and the fulcrum of the balance lever always counterbalances the required tension of the warp. As shown, the feeler F, which is held in contact with the warp on the beam A by a spring &c. moves vertically between rollers and carries one end of a chain passing over the pulley 3 to an arm T on a bar X carrying the operating weights W. The bar is supported at one end by a link S pivoted to the framework, and has a bracket Y at its other end carrying a runner U adapted to bear on the balanced lever L. A spring or other means is employed to move the bar to the left when the feeler rises and allows the chain to pass over the pulley 3. A greater traverse can be given to the bar by a compound pulley device from which the chain unwinds. A flexible connection is attached to the lever L and passes around a pulley P adjustably connected to one end of the chain or rope of the ruffle R, the other end of the chain or rope being connected to the framework at Z. The connection then passes around pulleys Q, Q<1>, P<1> and is connected at D<1> to a weight-releasing lever 8. The pulley P<1> is adjustably connected to one end of the chain around the ruffle R<1>. When the apparatus is applied to one end only of the warp beam, the flexible connection is attached at D" to the weight-releasing lever 8. In a modification, the weight-carrying bar X carries a bracket Y at each end, a balanced lever being employed at each end of the beam. In another modification, the flexible connection passes around pulleys on the longer arms of bell-crank levers pivoted to the framework, the other arms being connected to the ends of the chains passing around the ruffles on the ends of the warp beam.

Title: Improvements in or relating to fuel injection devices for internal combustion engines
IPC: F02M49/02
Filed: 1946-09-11
Abstract: 630,437. Fuel-injection pumps. MORRIS,A. J. and LISTER & CO., Ltd., R. A. Sept. 11, 1946, Nos. 27343/46 and 581/47. [Class 102(i)] A pump injector comprises a body 10, a reciprocating plunger 19 working in a cylinder 30 to deliver fuel intermittently to a nozzle 17, a spring-loaded gas piston 13 actuated in a chamber 14 by the pressure in the combuschamber, the piston 13 and the plunger 19 being operatively connected to move as one piece and arranged to provide a fluid cushioning buffer to arrest their movement at the end of a stroke. The fuel injection commences when a helical edge 41, on the plunger 19 covers an inlet port 36, in the cylinder 30, the fuel being forced through a duct 37, a port 47, around a neck 43 of the plunger 19 and through a duct 42 to a duct 18. past ball valves 48 to the nozzle 17. The injection stops when a spill port 38 in the cylinder 30 is opened by the neck 43 thus relieving the pressure within the ducts 18, 37 and in the cylinder 30. The lower lip of the neck 43 next closes the port 47 and the fuel trapped within the cylinder and duct 37 provides a hydraulic cushioning buffer for the end of the fuel injection stroke. Should the cylinder be empty cushioning is effected by a pad 23 in the piston 13 engaging the end of a sleeve-like extension 49 of a distance piece 11 secured in the body 10. A fall in pressure within the combustion space allows 'the gases within the chamber 14 to escape through a metering orifice 15a so tapered as to throttle the flow of gases thereby allowing the piston 13 to be stopped gently by an abutment 45 provided by a nut 15 at the nozzle end of the body 10, Concurrently fuel is drawn from delivery connection 27 to a chamber 28 and thence through the port 36 and partly through spill port 38 and duct 37 into the cylinder ready for the next injection stroke. The quantity of fuel delivery may be varied by rotating the cylinder 30 by means of lever 31 such that the point in the delivery stroke at which the port 36 is covered may be varied. An auxiliary means comprises a needle valve 50, Fig. 8, having an enlarged stem 51 mounted in a head 32 for controlling the flow of fuel to the duct 37 adjustment being effected by a nut 54 acting on a spring 53. The cylinder may be primed by loosening a plug 40 and injecting fuel through port 36 by pressure allowing air to escape through a duct 39.

Abstract: 1,179,704. Acoustic testing devices. JOSEPH LUCAS (INDUSTRIES) Ltd. 9 June, 1967 [20 June, 1966], No. 27429/66. Heading H4D. In a system for checking the resonance frequency of a cavity (e.g. in the trumpet portion of a vehicle horn) the cavity is placed in communication with the entrance 4 of a chamber 3 containing a sound emitter 7 operating near the fundamental or a subharmonic of the frequency at which the cavity should resonate, and the pressure wave amplitude within the chamber is measured and compared with that obtained when using a reference cavity. A resilient, annular member 5 provides a seal between the cavity and the chamber 3. The sound wave amplitude is measured by a microphone 10 feeding a transistorized amplifier (Fig. 2, not shown), bridge rectifier and meter. The system is calibrated to give a full-scale meter deflection when using the reference cavity and a sound frequency just off the reference cavity resonance. (It is stated that inconsistent results may be obtained when faulty cavities are tested if the actual resonant frequency is used.)
