Title: Improvements in or relating to winding machines
IPC: B65H59/38
Filed: 1954-05-18
Abstract: 751,166. Winding yarn. UNIVERSAL WINDING CO. May 18, 1954 [July 8, 1953], No. 14542/54. Class 120 (2). [Also in Group. XXXV] A winding machine comprises a rotatable winding spindle, means for traversing yarn, an electric motor having variable speed characteristics for driving the spindle, an alternating current supply for the motor, a saturable reactor having a load winding and a control winding, said load winding being in series with the motor and supply line, means adapted to engage the running yarn prior to its engagement by the traversing means and to move in response to tension changes therein, a source of direct current connected to the control winding, and means operated by the movement of the yarn - engaging means to control the flow of direct current through the control winding whereby the amount of current flowing through the load winding and motor is varied to vary the speed of the motor. As shown, yarn Y is fed at constant speed over an idler roll 84, under a dancer roll 82 carried by an arm 80 attached to a rotatable wheel 74 and thence to the reciprocated yarn guide 16 for winding on the core on the holder 24. A magnetic core 62, carried by a flexible tape 78 suspended from the periphery of the wheel 74, is arranged to co-operate with a coil 50 forming part of a bridge arrangement 42 fed with current from the secondary winding of a transformer 40 connected across the A.C. supply lines 30, 32. As the winding tension in the yarn Y varies, the core 62 will be raised or lowered in the coil 50 to produce a degree of unbalance in the bridge 42 so that current will flow in the conductors 52, 54, which on being rectified by the full wave rectifier 56 will flow in the control coil of the saturable reactor 38 to vary the current supplied to the motor 28. The supply line to the motor preferably includes a variable resistance 36 to a single pole single throw switch 34 which, in the event of yarn breakage or failure, is opened by a contact moved by a spoke of the wheel 74. The weight of the core 62 is compensated by a spring 92 connected to a lever 96 and to the hub of the wheel 74. For the purpose of gradually reducing the winding tension as the package builds up, an adjustable linkage 104, 108, 100, 96, moved by the traverse frame 20 as it recedes from the winding spindle 14, gradually lessens the spring-tension 92. In order that the spring- tension 92, operating through the linkage 96, 100, 108, 104, shall not unduly effect the pressure of the yarn guide upon the package, two modified forms of linkage are described through which the lever 96 is connected to the link 108 by way of an adjustable cam and lever-follower arrangement. Specifications 653,902 and 697,303 are referred to.

Abstract: 1304049 Anti-skid systems ROBERT BOSCH GmbH 26 March 1970 [27 March 1969] 14632/70 Heading F2F A compressed air, vacuum or hydraulic pressure fluid system for preventing a vehicle brake 3 from locking an associated vehicle wheel comprises a master cylinder 1 from which fluid can be transmitted through a brake line 2 for actuating the brake, a floating piston 7<SP>1</SP> provided in the line 2 and actuable by a servomechanism to relieve the pressure in the brake line in response to the associated wheel commencing to lock, the servomechanism including a two-way valve which, in a first position, connects the working chamber 9<SP>1</SP> of the servomechanism to atmosphere and which, when actuated by a signal issued from a wheel lock sensing device, moves to a second position in which the chamber 9<SP>1</SP> is connected to a source 20 of pressure medium and the piston 7<SP>1</SP>, and flow control means, including a throttle, for varying the rate of flow of pressure medium to and/or from the chamber 9<SP>1</SP>. As shown, the sensing device transmits a signal to solenoid 21 of the two-way valve whereby the closure member of the valve engages valve seat 14 so that pressure medium flows to the chamber, the pressure difference between the source 20 and the chamber being such as to raise the valve closure member 18 and as the pressure in the chamber approaches that of the source the member 18 is seated so that pressure medium now flows through throttling hole 15. The piston 9 and rod 8 are displaced so that the rod closes the bore 6 of the piston 7<SP>1</SP> whereby the pressure from the master cylinder 1 is reduced. Upon cessation of the signal from the sensing device the solenoid of the two-way valve is deenergized and the closure member of the valve engages the seat 13 so that pressure medium flows from the chamber 9<SP>1</SP> to atmosphere at 21<SP>1</SP>. In a modification, the inlets of the two-way valve are connected to the pressure source 20 and atmosphere via an accumulator and a throttling aperture.

Abstract: 594,905. Tenderising food. BERKEL & PARNALL'S SLICING MACHINE MANUFACTURING CO., Ltd. (U.S. Slicing Machine Co.). June 11, 1945, No. 14699. [Class 28 (ii)] A machine for tenderising food, e.g. by rotated knives 20 or teeth, is provided with an ultra-violet lamp 17 to dstroy any bacteria &c. on the food or in the machine. The food is fed in at the funnel 19. The machine has a removable cover 12 pivoted on hinges 14 and containing an ultra-violet U-shaped lamp 17. On lifting up the cover 12, an adjustable tappet 31 is freed from contact with lever 29 pivoted at 28 and allows the spring of a limit switch 23 to move a finger 30 outwardly to open the switch and rock the lever 29 counter-clockwise, thus breaking the circuit to motor 25, Fig. 7, and to the transformer 45 of the lamp 17. The circuit may be manually closed while the cover is open by sliding a knob 36, whereby a ramp 42, Fig. 6, on a slide block 39 contacts and pivots the lever 29 to close the switch 23, thus reconnecting the motor 26. The lamp circuit, however, has been previously cut out by hand operating a switch 44. In case the operator forgets to switch off the light by hand switch 44, an alternative switch 46 may be provided coupled to and operated by the slide block 39 at the same time as it closes the switch 23 so that the motor only can be started while the cover is open.

Filed: 1919-10-23
Abstract: 157,680. Smith, W. S., Salmon, P., and Ellor, J. E. Oct. 23,1919. Spray carburettors.-In a carburettor of the kind described in Specification 150,019 in which two Venturi tubes 13, 15 are nested together, the outer one being connected to the engine induction pipe and the inner one having at its throat a fixed nozzle 37 connected to a fuel reservoir at a lower level, the inner Venturi tube 15 is movable automatically by the engine suction against a spring 39 to act as a throttle valve for the secondary air passing through the outer Venturi tube and also to vary the suction at the nozzle 37. Fuel is lifted by suction from the main fuel reservoir', through a uon-return valve 55, an auxiliary reservoir 42 and a conduit 38 to the nozzle 37. The casing 40 of the spring 39 may be provided with a stirrup and rod 41 for manual adjustment of the throttling. The inner Venturi tube acts as a pilot tube for slow-running when in the closed position. When applied to aircraft engines, where the suction lift or negative head of fuel varies with the change of attitude of the aircraft, the carburettor may be fitted with a compensator for supplying the fuel under constant pressure. As shown in Fig. 6, the compensator is situated at the same level as the carburettor and comprises a fuel inlet valve 45 connected by a leak valve 54 to the underside of a spring-pressed diaphragm 44, the fuel passing through a conduit 49 to the nozzle tube 35. If the pressure in the chamber 47 rises, the diaphragm closes the valve 54, fuel leaks downward past the periphery of the valve 45, and the valve 45 closes or tends to close; if the pressure falls, the diaphragm opens the valve 54, thus releasing the fuel from the underside of the valve 45, which then opens. In a modification, the compensator, which is similar to that described in Specification 150,019, comprises a diaphragm carrying a needle valve controlling the outlet of fuel from the bottom of the fuel tank, the chamber above the diaphragm being connected by a pipe to the fuel nozzle, and the chamber below the diaphragm being connected by a pipe to an air space around the nozzle.
