Title: Improvements in and relating to advertising devices
IPC: G09F11/34
Filed: 1927-12-09
Abstract: 282,086. Farriols, A., (Assignee of Maumus, E.). Dec. 9, 1926, [Convention date]. Boards and like elements, travelling. - Independent advertising plates 1 are circulated from the front bottom end of an upper inclined guide 24 to the front top end of a lower inclined guide 23 whence they fall by gravity to the bottom back end and are raised in turn to the top back end of the upper guide 24. The plates 1 may be built up of front and back metal borders screwed together with the display sheet between. The mechanism comprises an endless chain, moving uniformly or intermittently, fitted with a finger which engages a roller on a counterbalanced frame 2. A pivoted spring-pressed hook 15 on the reciprocating frame 2 engages extensions 31 on the advertising plates 1 and lifts them over a pivoted spring-pressed hook 27 at the rear of the upper guide 24, upwardly extending blade springs on the frame 2 having previously forced forward the rear plate 1 hanging from the top guide 24. A wedge device 18 fixed on a support 14 mounted on the frame 2 separates the front plate 1 from the pack and lifts it over a beak 26 on the guide 24 so as to lower it, when the frame 2 descends by gravity, to the lower guide 23. Springs at the bottom and sides of the casing cushion the frame 2 in its fall. In a modification the frame 2 is shorter and is provided with a horizontal slot which is always in engagement with a projection on the chain. This causes a slow downward removal of the discarded plate, and in order to lengthen the relative time of exposure the chain may be caused to follow an extended path. The frame 2 may be provided with double guides at each end. Reference has been directed by the Comptroller to Specification 118,996.

Abstract: 381,393. Plug couplings. CLAYTON, C. E. EVERY-, 51, Chancery Lane, London.- (Gottlieb, D. ; 40, Strassburger Strasse, Berlin.) Dec. 2,1931, No. 33446. [Class 38 (i).] A socket consists of a cylindrical piece of rolled sheet metal having one or more inwardly-projecting resilient parts, which are formed by making longitudinal cuts parallel to the axis of the socket and extending over the whole or a part of the length of the piece, and which are of sharper curvature about the axis than the body of the piece, so that each of the projecting parts makes a straight line contact with the plug. As shown in Fig. 2, one end 2 of a cylinder 1 is bent inwards so as to bear against the plug ; overlapping of the free end may be prevented by forming a rectangular part 5 on the end 2. The upper corner of the end 2 may be sloped so as to facilitate insertion of the plug. Both ends of the cylinder may be bent inwards. As shown in Fig. 9, a double T-shaped slit is made in the cylinder, and the flaps 11 thus formed are bent inwards ; the top corners of the flaps may be inclined backwards, and the ends 13 of the cylinder may be made of larger diameter than the middle part, so that when the socket is inserted in an inexpansible block or tube 14 the middle part has room for expansion. The socket has a tail connecting piece at the lower end, or the end may be formed as a plug. The bent flaps may be formed with circumferential slits to increase resiliency ; or a circumferentially running corrugation may be formed at the centre of the flap so that there is no resiliency at the ends.

Title: Method of making embossing rolls and embossing rolls made by such method
IPC: B44B5/02
Filed: 1953-12-03
Abstract: 737,440. Making embossing rollers. SUNDERHAUF, F. A., and O'HEAR, J. C. Dec. 3, 1953, No. 33653/53. Class 83 (2). [Also in Group XVI] A pair of mated engraved steel rollers for embossing sheet material are made by engraving an upper relatively soft roller 1, e.g. by forcing a hardened master roll against it, so as to produce projections thereon, hardening this roller, fixing a gear-wheel 3 on the shaft 2 thereof, coating a lower roller 5 having a similar gear 7 with an acid-resisting wax 11, Fig. 9, pressing the upper roller against the lower roller to produce waxed and unwaxed areas on the lower roller as shown in Fig. 9, lowering the lower roller into an acid bath 12, Fig. 10, to eat away metal from the exposed areas, and washing off excess acid. The process of coating the lower roller with wax, pressing the upper roller against it to impress its pattern on the wax and treating in the acid bath 12, is repeated several times using successively greater pressures until the lower roller is mated with the upper. The lower roller is then given a further acid treatment to produce a predetermined clearance between the projections of the upper roller and their mated recesses on the lower roller, as shown in Fig. 11, to avoid cutting or damaging material 14 being embossed. The acid may be nitric or acetic acid. Each successive rolling operation to impress the pattern of the upper roller upon the wax coating of the lower roller is carried out with increasing pressure so that the rollers bend slightly and cause the markings in the wax coating to be deeper at the ends of the rollers. By this means a slight bulging of the lower roller is obtained, the diameter of the central portion being a little greater than that at the ends. This compensates for bending of the rollers during use and equalizes the embossing pressure along the length of the rollers.

Abstract: 1481221 Injection moulding SCHLOEMANN-SIEMAG AG 1 Aug 1974 [11 Aug 1973] 33949/74 Heading B5A In a method of injection moulding plasticized synthetic material containing a blowing agent a temperature difference is produced between inner and outer zones of the injected material so that the viscosity of the material in the outer zone is substantially higher than that in the inner zone. This is effected by applying heat to the inner zone or cooling the outer zone or both. In the example shown in Fig. 1 heating is effected by a cartridge heater 6 in a tube 5 and cooling by fins 14 on a bushing 12. The tube 5 extends from and may be axially displaceable in a needle 3 which can be moved axially by linkage 4 to act as a valve. The tube 5 may be axially slidable in the needle so that when the needle closes the outlet of nozzle 2, the forward end of the tube closes the injection mould inlet.
