Title: Improvements relating to containers
Inventor: WALSH JAMES JOSEPH
IPC: B65D17/40
Filed: 1961-11-14
Abstract: 945,985. Opening containers. A. R. D'ANDREA, and W. F. BECKER. Nov. 14, 1961, No. 40772/61. Heading B8D. An end wall 214 of a container may be stamped from metal sheet and is opened by means of a pull tab 227 cut or stamped in the end wall. An interrupted slit 224 extends round the end inside the peripheral seam and a frangible sheet 234, e.g. of aluminium foil or plastics material, is secured by a layer of adhesive 235 to the inner side of the end wall so that, on pulling the tab 227, the whole of the container end may be removed. The slit may be replaced by a weakened portion in the metal end wall. In a modification, Fig. 10 (not shown), a sectoral opening is formed in the container end, the pull tab being joined to the end wall either at the apex of the sector or on its curved outer edge, Fig. 13 (not shown). Again, Fig. 23, a strip of metal having a lower leg 332 is applied to an aperture formed in the end wall of a container, and a frangible sheet secured on the underside, so that the strip may be torn away to break the frangible sheet and form a pouring opening. A spur 340 pierces the sheet, as the tab is bent backwards, and before the main aperture is made, so releasing any gas formed in the container. The tab is held down by means of a tongue 336 which passes through a hole 339 in the tab. In the form illustrated in Fig. 28, the lower leg 361 of the tab strip underlies and is broader than a preformed opening 355 in the container end wall. Spurs 367 on the lower leg 361 are initially flat, but when the tab is pulled upwards they are forced down by the edges of the opening 355 thereby piercing a frangible sheet secured below.

Abstract: 1,188,329. Coating wire. BRITISH INSULATED CALLENDER'S CABLES Ltd. 13 Sept., 1968 [14 Sept., 1967], No. 41926/67. Heading B2K. [Also in Division D1] A process of enamelling a wire comprises preheating the wire to a temperature in excess of the boiling point of the solvent of the enamel solution and applying a plurality of coatings to the hot wire before it passes into a baking oven, the interval between successive applications being such that flash evaporation of the solvent from each coating occurs before the next coating is applied. The coatings may be applied within a single closed chamber through which the wire passes or two or more separate closed chambers may be used and one or more than one coating applied in each. Preheating of the wire may be effected by passing the wire through a hot liquid or through a fluidised bed of heated inert powder or through a heated inert gas, or by means of high frequency induction heating or by resistance heating or by a wire drawing operation. Wire of diameter 0.25 millimetres and upwards may be used. In an apparatus which is described a wire 1 passes through fluidised bed 6 of silica heated by heating elements 8. The wire then passes successively through a series of applicators 10 which have cavities into which enamel solution is fed from a pipe 11. The solvent is removed from the enamel by flash evaporation in the zone 4 between the coating stages. Finally, the wire enters the curing ovens 5.

As shown the primary transducers are light emitting diodes arranged in a rectangular matrix 12, 13 and co-operating with a lightsensitive probe 19. The secondary transducers may be similar, may alternatively operate on magnetic, capacitive or inductive principles, or may be replaced by push-button or other switches. Instead of a matrix, a fixed row of light emitting devices co-operating with a movable column thereof may be used (Fig. 7, not shown).  The position of point P is measured relative to a chosen origin A whose co-ordinates Xa, Ya are entered on, e.g. thumbwheel switches 17, 18. The absolute co-ordinates of P are then Xa+ X +x, Ya+Y+y (Fig. 6, not shown). To obtain X and Y, probe 19 is placed at the required point, and the diodes are scanned in turn using a counter 45 and a register 40. When the diode at B, Fig. 3, is energized, a signal from probe 19 stops the scan, and the required co-ordinates are fed from register 40 to a computer 44. A similar circuit controls the secondary transducers (Fig. 5, not shown) to obtain x and y probe 19 being placed on matrix 15 to correspond with the position of point P in its area 11. The above apparatus may be used to display the co-ordinates of a point P obtained from computer 44, the appropriate diodes being lit. In this case the secondary diodes may be replaced by numerical display devices.
