Abstract: 800,870. Moulding concrete pipes, posts &c. AUCAMP, J. D. Oct. 13, 1955 [Oct. 22, 1954 ; July 5, 1955], No. 29219/55. Class 87(2). [Also in Groups X and XXVIII] Concrete &c. pipes are cast in situ between shutters 1 and a core 10 which is rotated and withdrawn by a handle 23 and bevel gear 19. The shutters 1 are supported by yokes 7 and the core 10 is supported by a bearing 15 on a slide 16 carrying the handle 23. A cable 28 is connected to an end yoke 7 and is adapted to be wound on a drum 24 when this is connected to the handle 23 by a clutch 25 to move the slide 16 along the top of the shutters 1 and withdraw the core 10. The core 10 passes through a bridging member 9 between the shutters which carries a core cleaning rim 11. A sleeve 13 forms a socket in the end of the pipe to guide the end of the core into position for casting the next length of pipe. Branch pipe fittings 37 may be cast in the pipe. Pure cement is sprinkled on top of the core when the level of concrete is just below the top of the core and the core trowels the cement to form a bore with smooth and water impervious surface. Dolomite may be added to form an acid resisting coating. An expansion joint is formed in the pipe by a briding plate in two halves so that it may be removed. Reinforcing wire, as a preliminary step is wound round the core 10 and subsequently cast in the pipe. The bridging member 9 may have an attachment to mould a socket in the end of the pipe and a plate at the other end of the pipe moulds a spigot. To cast a longer pipe, e.g., for a fencing pole a short core 39, Fig. 9, abutting the end of the core 10 and adapted to be turned by a handle 40 is supported by a bridging member 38 at the end of the shuttering 1.

[Also in Divisions E2 and F2] A closure for openings such as nuclear reactor standpipes comprises a body which forms a fluid-tight joint with a peripheral wall surrounding it, radially movable locking member disposed about the body and engageable with the standpipe, and a member axially disposed about the body and axially movable between a first position in which the locking members are held extended and a second position in which the locking members are allowed to retract. The upper end 11 of the standpipe includes an angular seating 36, a keyway 15, on annular sealing surface 13 and a locking groove 18. The plug comprises a body 10, on angular seating 35, sealing rings 12A, 12B, a cage 16 which is rigidly attached to the body 10 and supports the locking members in the form of balls 17, an axially slidable locking ring 19 for locking the balls 17 in position and having mounted in its top surface dowels 26 which, in the locked position shown, engage the under surface of a retaining ring 24 rotatably mounted on the body 10. To unlock the closure, grab arms 20 having fingers 21 on their lower ends are lowered past the retaining ring 24 by way of slots 30 therein and past similar slots 31 in the locking ring 19 to the position shown. Rotation of the grab causes the fingers 21 to move out of alignment with the slots 31 in the locking ring 19 to a position beneath a flange 23 in which the slots are situated. A key 34 on the grab arm 20 caused the retaining ring 24 to rotate against spring biasing to a position in which the dowels 26 are aligned with holes 26 in the retaining ring. Upward movement of the grab arms pulls the locking ring upwards to a position which allows the balls to be retracted and, when the top of the locking ring contacts the undersurface 27 of the retaining ring 24, withdraws the plug bodily from the standpipe. The plug may be used to entirely close an opening, or may itself have an opening therethrough.

Title: Methods of winding capacitors
IPC: H01G13/02
Filed: 1971-06-24
Abstract: 1338825 Capacitors ILLINOIS TOOL WORKS Inc 19 Jan 1971 [20 Jan 1970] 29748/73 Divided out of 1338824 Heading H1M In a method of winding a capacitor from a single strip of dielectric material metallized on both surfaces, the strip is folded at about its middle and the folded portion is wound around two lead wires brought into contact with the opposite surfaces at locations such that, when winding is continued using the lead wires as mandrel, they become separated in the roll by at least three thicknesses of dielectric strip, the folded portion wound into the roll increasing the effective mandrel diameter and permitting winding with fewer turns, and the ends of the strip being sealed to the underlying portions of the roll on completion of winding. In one embodiment (Fig. 13), strip 114 is folded twice around pins 116, 118 which are withdrawn as lead wires 148 175 are rotated as one to wind the roll. Preferably however, the fold is formed and winding carried out using the apparatus illustrated in Fig. 1B, wherein the free end of metallized strip 14 is secured to block 20 slidable in chute 22 and the tension in strip 14 is adjustable by weights 30, 40. Initially the strip passes between a first lead wire 48 and a retractable pin 54, the lead being supported between a slot 50 in winding head 52 and a support 58. Rotation of winding head 52 about its axis 49 causes pin 54 to orbit round lead 48 to form the loop (Fig. 3) and orbiting is continued so as to carry the loop at least once round lead 48 before second lead 75 is brought into contact with the opposite metallized surface of the strip (Fig. 5). During orbiting lead 48 has moved to the other end of slot 50 permitting lead 75 to be introduced along the same axis-that of the winding head-as was lead 48, so that the leads may be supplied from the same spool. Pin 54 is now rotated about its eccentric axis 76, effectively moving it radially inwardly (Fig. 6, not shown), and separating it from the strip to some extent to permit its withdrawal. Continued rotation of head 54 winds in the loop. On completion, the supply strip is clamped at 78 and severed, adhesive tape 21 securing the leading end of the strip to block 20 is removed therefrom and used to secure the strip ends to the roll. The strip may be of heat-shrinkable material, e.g. polypropylene of polyester film and the completed roll may be heat-treated to shrink the material and secure the leads in the roll (Fig. 14). The leads, both extending from both ends of the roll, may be bent and/or severed to give a desired configuration.
