Class 135 A float-operated valve for flushing cisterns and the like comprises a valve stem 4 which is formed as a unit with the valve closure member 6 and carries a resilient member 9 by which pivotal movements of the stem within an opening 8 in the valve casing 3 are resiliently resisted. The valve stem 4 is rigid with the usual float arm 5 and has a flange 4a above which is a boss adapted to receive a collar 9 of rubber or other resilient material. The collar has a flange which fits snugly in the opening 8. A pin 10 passes through the boss and the collar to support the valve stem hingedly. The valve closure member comprises a sealing ring 6 of rubber or other suitable material on a flanged collar 11 which is retained on a reduced part of the stem 4 by a nut 15. The ring 6 is preferably of curved contour and may be rotated to present a fresh surface to the valve seat 7.

Filed: 1954-04-02
Abstract: 748,249. Carpets and rugs. WAAGE, J. April 2, 1954, No. 9672/54. Class 142 (4). Carpets and rugs are made by winding yarn 11 spirally on to flexible cores 17 or 23, winding one or more cores on to a drum carrying a backing material, securing the yarn to the backing with rubber latex, and cutting the yarn and removing the cores. Strips, ribbons, or waste cuttings may be used instead of yarn. Patterns may be obtained by printing the yarns before or after removal of the cores, or by using different coloured yarns. The cores may have two spiral layers of yarn thereon. The pile is cut by a rotating knife, indicated at 21, engaging slots in the cores. The top of the pile may be trimmed by a knife indicated at 26. The cores are made by extruding a thermoplastic material. An intermediate layer of linen 28 impregnated with rubber latex forming adhesive layers 29, 29a may be interposed between the yarns 11 and a canvas or hessian backing 27. In one embodiment the wound cores are stored on a drum and the backing and intermediate linen sheet are stored on separate beams. The ends of the cores, of the intermediate sheet, and of the backing sheet are all secured to a further beam and wound thereon, the intermediate sheet passing through a bath of adhesive. In a further embodiment (Fig. 5) a drum 70, equal in length and circumference to the size of rug required, is driven by a chain 75 from a motor 76b and a reel 79 holds a single continuous length of a wound core 77. The.drum 70 has a backing sheet 78 secured thereto and the core is wound on to the drum, passing over an adhesive coating device 85 and through guide means 82 on a screw 83 which is geared to rotate with the drum. A cutting device is subsequently substituted for the guide means 82 and the yarn severed and the core removed. The drum may be heated.

Abstract: 117,135. Shiels, A. D. July 6, 1917. Embossed and relief photographs.-Relates to relief prints of the type in which the print is modelled from the front upon a backing of plastic material, and consists in cutting the print to the outline of the figure or image, securing it upon the cast formed from a hand-made model, and finishing off the edges of both. Plastic clay is placed upon a modelling board and covered with a sheet of flexible material, e.g. paper, bearing the printed photograph. It is then modelled by hand and a permanent mould g, Fig. 5, preferably of plaster of Paris mixed with any fine cement, is prepared therefrom. Any number of casts b, Fig. 2, are taken from this mould, and each is secured to a backing-board a in order that a photographic print c on thin paper, cut to the outline of the figure, may be affixed to the face of the cast. The edges of the figure are then finished off or covered in any suitable manner. Alternatively the cast may be unmounted or may have a backing cut flush with the edge of the figure. Reference has been directed by the Comptroller to Specification 27076/09.

Title: Improvements in and relating to electric control systems
IPC: B23K11/24
Filed: 1939-03-29
Abstract: 529,973. Supply systems for resistance welding. BRITISH THOMSON - HOUSTON CO., Ltd. March 29, 1939, No. 9825. Convention date, March 29, 1938. [Class 38 (iv)] A.C. is supplied to a welding circuit 1, 3 from an A.C. supply by means of two groups 4, 5 of valves, the valves in one group being arranged reversely to those in the other group. The valves in each group are controlled to operate sequentially by means of a switch 51 which determines the connection of the control electrodes of the valves in the excitation circuit, to permit the valves to be operated at a higher rating than the normal continuous load rating. The contacts 55, 56 and 61, 62 of the switch 51 are sprung so that during changeover a control electrode of one valve in each group remains connected in the excitation circuit. The switch 51 is operated by a coil 50 intermittently energized from a supply 66 by means of a relay 64 which is periodically energized and de energized by means of a further relay 65. Excitation circuits 12 13 are provided for the groups 4, 5 respectively ; an impulse from the control circuit 27 applied across the resistance 26 causing the valve 14 in the circuit 12 to conduct and initiate discharge in the particular valve of group 4 to which it is connected by the switch 51. The impulses for controlling the group 5 of valves by means of the circuit 13 are derived from across the transformer 3 in the load circuit The impulse generator circuit 27 is of the kind described in Specification 495,700, [Group XL], the phase of the impulses being adjustable by means of a phaseshifter 44. Condensers 25 are connected in the grid circuits o: the valves 14 to dissipate any transients which may occur Specification 486,349 also is referred to.

Title: Improvements in or relating to lifting-trucks
IPC: B62B3/06
Filed: 1919-04-17
Abstract: 149,722. Spencer, H. E. April 17, 1919. Hand-trucks. - Mechanism for locking in the raised position the loadcarrying frame of lifting- trucks of the kind adapted to be run under the load, comprises a locking pawl which is held engaged as by the weight of the load-frame and is disengaged by a spring when relieved of that weight, the spring being connected to a lever or equivalent so that it is stressed only when it is desired to lower the loadframe, thereby avoiding undesired disengagement of the pawl. Figs. 1 and 2 show the mechanism applied to a truck of the kind described in Specification 149,720 in which the load-frame A is pivotally mounted at the front end upon a crossmember F in which the steering-wheels Bare mounted and which is rocked about the axle L of the wheels B by the handle M for raising and lowering the frame A. The locking pawl N is pivoted at N' on the frame A, and is connected by a spring P to a hand lever O pivoted at O<1> on the frame A. Normally, the lever O rests against a pin Q on the frame A, as shown in Fig. 1, with the spring P relaxed. When, for raising the frame A, the cross-member F is rocked from the position shown in Fig. 1, to that shown in Fig. 2, an abutment F<4> on the member F moves into engagement with the pawl N and so holds the parts in the raised position. When it is desired to lower the frame A, the lever 0 is moved to the position shown in Fig. 2 in which a pin O<2> thereon rests on a cam surface F<6> on the member F, thereby tensioning the spring P, which then holds the lever in this position. On moving the member F slightly in the frame-raising direction, so that the weight of the load is taken off the pawl N, the spring P raises the pawl and the load-frame can then be lowered. As the member F is rocked, the cam-surface F<6> moves the lever 0 sufficiently for the spring P to return it to the position shown in Fig. 1. The lever 0 may be a foot-lever, and its return movement may be initiated by the coupling-bar E or other part instead of, or in addition to the member F. The pawl may be adapted to lock the frame A in one or more partly-raised positions.
