Title: Apparatus for weaving shaped fabrics
IPC: D03D3/00
Filed: 1957-08-19
Abstract: 871,743. Weaving shaped tubular fabrics. KOPPELMAN, E. Aug. 19, 1957 [Nov. 20, 1956], No. 3877/61. Divided out of 871,742. Class 142(2) Tubular fabrics of varying cross-section are woven in a flat loom by mechanism which brings the warp threads to four levels to form two sheds for insertion of weft and then moves them to the positions they occupy in the fabric whilst the weft is being beaten up. The warp threads pass through tubular heald eyes 320 mounted between the blades 302 of the reed. The blades are curved to suit the particular fabric being woven in order that when the eyes 320 are moved into position for beat-up, the warp threads are equally spaced round the fabric. The blades are duplicated to guide the front and rear ends of the eyes 320 and are of angle section, their flanges 316 being shaped to provide, in conjunction with the web 314 of the next blade, a slot of uniform width for the eye to ride in. The eyes are suspended on lifting wires 328 hung on guide bars 330, 332. The rear ends of the bars are lifted by jacquard mechanism 336 to form sheds and the forward ends rest on rollers 340, 342 which slowly rotate as weaving proceeds; the rollers 340, 342 have profiles corresponding to the successive contours of the upper and lower halves of the fabric respectively. As the reed 300 beats up a weft, the lifting wires 326 slide along the guide bars 330, 332, thereby causing the warp threads to take up positions determined jointly by the rollers 340, 342, and the blades 302 of the reed.

Abstract: 158,904. Compagnie des Forges et AciÚries de la Marine et d'HomÚ- court. July 10, 1919, [Convention date]. Sights.-Relates to means for sighting machine guns or automatic rifles mounted on armoured vehicles, and consists in mounting the gun on a universal joint, and transmitting its elevating and training movements to a universally mounted periscope whereby the axis of the gun is kept parallel to the line of sight. The invention is shown applied to an armoured vehicle of the kind described in Specification 149,242. The muzzle of the gun A is universallypivoted at 55c', 55b in an embrasure 55 in the armour of the vehicle, and the breech end of the gun is counterbalanced by a weight 70d suspended from a cable 70e passing over pulleys. The periscope 71 is trunnioned at 69b in a ring 69 which can be traversed in a fixed frame 69a. An arm 41 on the gun. and a link 67 pivoted at 67a to the ring 69, are connected by sliding rods 61, 66, to a lever 63 which is ball-jointed to the armour at 64. Training movements of the gun are therefore imparted to the periscope by turning the ring 69 in the frame 69a, and, during elevation of the gun, the periscope is turned about the trunnions 69b by a link 70b pivoted to the link 67.

Title: Improvements relating to voltage control circuits
IPC: H02P9/42
Filed: 1948-02-18
Abstract: 642,341. Automatic voltage and frequency control systems; rectifying. METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. Feb. 18, 1948, No. 4777. Convention date, May 22, 1946. [Classes 38 (ii) and 38 (iv)] [Also in Group XL (c)] In a voltage multiplying circuit of the kind in which a condenser is charged through a rectifier during one half cycle, and the voltage across the condenser is added to the supply voltage during the other half cycle, the said rectifier is grid-controlled so as to control the output voltage. An adjustable A.C. voltage tapped off potentiometer 2 is applied to the multiplier which comprises the grid-controlled rectifier 6, charging condenser 5; and rectifier 7, charging condenser 8. The output is affected through a filter 9, 10 between the reflector electrode 19 and the control electrodes' 18 of a reflex velocity-modulated oscillator 11. The voltage required between the cathode 17 and the electrodes 18 is provided by an unregulated full wave rectifier 12, 13. The two supplies are interconnected by a resistance 29 to prevent the reflector electrode 19 becoming positive with respect to the cathode 17. As the voltage on the reflector electrode partly determines the oscillator frequency, a constant frequency is maintained by coupling the resonant cavity 20 of the oscillator to a frequency discriminator 14 tuned to the required frequency and deriving therefrom a bias voltage which is applied to the grid of rectifier 6 to correctively vary the output voltage of the multiplier. In a modification, Fig. 2 (not shown), instead of the oscillator circuit, a resistance in series with a gas discharge device is connected across points A and B, and the voltage across the resistance is used to bias valve 6 to obtain a constant voltage output.

M. van ; 33, Boezemsingel, Rotterdam, Holland) Feb. 19, 1935, No. 5288. [Class 28 (ii)] In a slicing-machine, the abutment, or slice-thickness gauge plate, is formed with a slice-engaging portion which moves in unison with the substance to be sliced. In the Figure the abutment consists of a number of endless flexible bands, or belts, 10 passing around diametrally reduced portions of vertical end rollers 11, 12, backing rollers 21 being also provided. The rollers are journalled in a frame having top and bottom members 14, 15 and side members 16, 17, the frame being secured to a rod 18, which is adjusted longitudinally for slice-thickness regulation, and is slidable on a fixed guide 19. The rollers 11, 12, 21 are journalled in ball bearings 22 to reduce friction, so that the substance resting against the belts 10 entrains them as it moves towards the knife 13. The gap between the knife edge and the belts is filled by a comb-like member 20 having a rearwardly extending flange by which it is attached to the frame members 14, 15. In modifications, the backing rollers 21 are replaced by a smooth plate, or by smaller rollers which bear only against the front stretches of the belts 10. The moving abutment need not be endless but may instead be arranged to roll itself up at one end, e.g. the end adjacent to the knife. In a further modification, a tined slice stack conveyer is substituted for, and driven non-positively in the same manner as, the belts 10, a swinging discharge fly being provided. The stacker conveyer may consist of a single wide band of rubber or other flexible material.
