Abstract: 698,827. Making paper bags. DICKINSON & CO., Ltd., J. May 12, 1952 [April 27, 1951], No. 9870/51. Class 94(ii) Comprises apparatus for gumming the end 15, Fig. 4, of a flat tubular blank BT and folding it over to form the bag bottom. The blank BT, Fig. 1, is fed from conveyer tapes 12, between the adhesive-applicator roll 1 and anvil roller 2 so that an adhesive-transfer pad 16, registers with the blank end. The roller 2 rotates in a water bath 9 and is scraped by the rubber doctor blade 10. The end of the blank remains adhered to the pad 16 and is also held by one of the suction nozzles 42a to be carried towards the bottom end fold-forming gripper cylinder 3. When a tucker blade 18 just behind the pad 16 registers with the space between a nipper bar 24 and anvil block 25, on the gripper cylinder 3, cam means 39 cause the blade to move outwards and tuck a fold of the blank between the bar 24 and block 25. The bar 24 thereafter is moved by cam means 29 to nip the fold line and initiate the end folding which is completed when the end of the blank is stripped from the pad 16. The folded end is then drawn between the ironing tapes 28 and the surface of cylinder 3. The gripper mechanism is released by the cam 29 when the completed bag reaches the stack of bags lying against the stacker plate 35. Details of the cam mechanism and suction valves associated with the supply to nozzles 42a are described, Figs. 2, 3 (not shown).

Abstract: 1,143,381. Cathode-ray tubes. RANK ORGANISATION Ltd. 4 March, 1966 [9 March, 1965], No. 9892/65. Heading H1D A cathode-ray tube comprises a face-plate having a planar inner surface and formed of an assembly of optical fibres 11 in which the fibres in at least the marginal zones of the face-plate have their axes inclined to the axis of the tube so that their outer ends lie nearer the centre of the face-plate than do their inner ends so as to reduce pin-cushion distortion of optical images transmitted through the face-plate. When the tube is used in conjunction with an imageforming optical system, e.g. a spherical mirror, then the optical fibre face-plate may, in addition, have its outer surface formed so as to coincide with the focal surface of the mirror and thus reduce image distortion due to this surface being aspheric. The luminescent screen 8 may be replaced by a screen which is electrically sensitive to incident light.

Hollow cup-shaped or tubular workpieces such as shell cases 4, Fig. 5, bearing races or steel cylinders, are made by piercing a blank 4, Fig. 1, by a mandrel 5, and then passing the pierced blank whilst retained on the mandrel between radially acting swaging tools 1. The blank 4 which is preferably of square section, is placed inside a guide 3 against an hydraulically biased backing member 7 and is wholly or partially pierced by the mandrel 5 movable in a sleeve 6 which moves initially with the mandrel under hydraulic pressure into the guide 3, Fig. 2 (not shown). Thereafter a throttle valve is opened allowing the backing member to move to the left under pressure of the mandrel and the pierced workpiece is thus swaged by the tools 1 which are radially adjustable for varying their stroke position. The mandrel and sleeve with the workpiece are then withdrawn and the sleeve is moved forwardly relatively to the mandrel to eject the workpiece 4 therefrom. The face of the backing member may be recessed to receive the mandrel when the blank is wholly pierced.
