Title: Improvements in picking and shedding mechanism for looms for weaving
IPC: D03D49/24
Filed: 1959-07-09
Abstract: 933,073. Picking motions; shedding motions. K. MOUNG. Jan. 1, 1960 [July 9, 1959; Aug. 11, 1959], Nos. 23585/59 and 27367/59. Class 142 (2). Picking motion, Fig. 2.-The picking impulses are provided by strikers 13 on flywheels 8, one at each end of the crank-shaft, acting on levers 14 which are brought alternately into range of the strikers by cams 31 on a half-speed shaft 5. The impulses are transmitted to the pickers by arms 23 fixed on the levers 14. Each cam 31 reciprocates a sliding bar 11 (with a dwell at each end of the stroke), the bar being coupled by a link 20 to a lever 16 which acts through a spring 32 on the lever 14, whereby the lever 14 is moved into and out of picking position but can move relatively to the lever 16 when operated by the striker 13. To enable the loom to be turned backwards without affecting the pickers, each lever 14 has a tip 12 pivoted to it at 15 and normally held by a spring 15 against an abutment 21 on the lever 14. Shedding motion, Fig. 9.-The sliding bar 11 at one end of the loom is coupled by a link 42 to an arm 43 fixed on a shaft 45; the oppositelymoving sliding bar at the other end of the loom similarly oscillates the shaft through a link 42a and arm 43a. At each end of the loom, a rocker 46 on the shaft 45 operates shedding levers 51, 52 through links 49, 50. Bars 61, 62 rigidly attached to heald frames 63, 64 carry pins 59, 60 engaging slots in the shedding levers.

Filed: 1944-11-28
Abstract: 587,698. Moulding by extrusion. WALKER, L. Nov. 28, 1944, No. 23685. [Class 87 (ii)] [Also in Group II] Plastic material is prepared by introducing relatively dry granular material in scattered form into a zone of reduced pressure and simultaneously spraying liquid into the zone in predetermined amounts in relation to the amount of granular material. The granular material and the liquid may be introduced intermittently into the zone, wherein the pressure may be in the neighbourhood of 2 1bs. per square inch absolute. Apparatus comprises a chamber 1 connected to a vacuum pump 11 through a washer 13 and a filter 16. Granular material is admitted through a rotary valve 3 with pockets 4 driven by a gearing 5. The latter also drives a cam 9 which operates a poppet valve 7 to admit a spray of liquid through a nozzle 6. Pressure is applied to the mixture by mixing arms 23 on a rotary shaft 20, which also carries curved arms 19 to propel the material through an outlet 18. The latter is sealed at the commencement of the mixing with a plug of the plastic mixture, in order to maintain a reduced pressure in the chamber 1. In a modified apparatus the arms 19, 23 are replaced either by a pair of pressure rolls or by an extrusion screw. Air may be admitted through the inlet valve for the granular material, at each delivery of the latter, to apply an increased pressure to assist in the mixing of the materials already delivered to the vacuum chamber.

Title: Improvements in electric relays
IPC: H01H53/10
Filed: 1935-08-28
Abstract: 461,817. Induction relays. GENERAL ELECTRIC CO., Ltd., and BARRELL, F. Aug. 28, 1935, No. 24067. [Class 38 (v)] An electric relay adapted to close a contact against a biassing force comprises a rotary operated member and a rotary biassing member which have axes of rotation disposed sidewardly of one another and connected together by a link in such a way that the control exerted by the biassing force decreases during the final part of the contactclosing movement. As applied to an induction disc relay, the disc or discs are mounted on a vertical spindle O Fig. 1, and the spiral control spring acts in a clockwise direction on a parallel spindle R. The spindles O, R carry cranks 1, 2 the free ends of which are joined by a link 3, the distenals OL and LK being equal and the distance LK being greater than the distance between the axes O, R. With this mechanical arrangement it is shown in the Specification that with a large angular . movement of the induction disc shaft that the control force exerted by the spring will, during such movement, rise to a maximum and, during the final part of this movement during the approach of the controlled contacts to their engaged position, the biassing force will decrease from this maximum value, thus ensuring adequate contact pressure. The control spring may be arranged with or without an initial tension, and usually the stress on the spring will be adjustable.

Title: Improvements in electric discharge tube oscillation generators
IPC: H03B9/10
Filed: 1934-08-21
Abstract: 437,473. Valve generating circuits. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and MEGAW, E. C. S., c/o General Electric Co., Wembley, Middlesex. Aug. 21, 1934, No. 24134. [Class 40 (v)] Overloading of a split - anode magnetron oscillator 1 is prevented by automatically applying a negative voltage to a grid 3 within the magnetron when the energy taken by the load 8 is reduced, The output coil 6 of the magnetron is variably coupled to the load circuit 7 and to a coil 11 connected in circuit with a rectifier 12 and a condenser 13. The grid 3 is connected to the negative side of this condenser, and its positive side is connected to a positive tapping on a potentiometer 14 across the anode supply source 9. When the load 8 is reduced or removed the voltage across the coil 11 rises, and the grid becomes more negative, cutting down the anode supply current and preventing overheating in the valve. In a modification, a grid-leak rectifier is employed in place of the diode 12, and the reduction in its anode current caused by removal or reduction of the load 8 releases a relay. Thereupon one switch is opened to place a grid-biassing resistance in the anode supply circuit, and a second switch is closed to short-circuit a variable series resistance in the relay circuit. The relay coil may be shunted by a variable resistance. Instead of employing a rectifier, a gaseous discharge tube placed near the oscillator may be caused to initiate a discharge when the field strength rises, and the discharge current may be used to apply negative bias to the grid 3. The oscillator may be used in connection with electro-medical apparatus, or in treating materials by high-frequency fields. Specifications 400,995 and 408,641 are referred to.

Abstract: 863,755. Control of A.C. motors. LANCASHIRE DYNAMO ELECTRONIC PRODUCTS Ltd. Oct. 16, 1958 [July 30, 1957; April 30, 1958], Nos. 24146/57 and 13752/58. Class 38 (3). [Also in Group XXXV] A control system for a servomotor M comprises transistors Tr1, Tr2, supplied from a fullwave bridge rectifier D, the connections of the transistors to a centre-tap of supply transformer T1 being made through a control winding W1 of the motor. The input to the transistors is derived from control element E generating a control signal in phase with or in phase-opposition to the A.C. supplied to the transformer T1 for determining the sense of operation of the motor. The control element is coupled to the transistors by transformer T2 so that its output is 'applied oppositely to the inputs of the two transistors which conduct on alternative halfcycles of the supply voltage. An alternating- current is thus developed in winding W1 which reverses in phase when the control signal is reversed. The transistors may be substituted by thermionic valves, Fig. 2 (not shown). Each limit switch LS cuts off those half-cycles of rectified current that energize the motor during movement towards the limit of travel at which the switch operates to stop the motor.
