Title: Improvements in and relating to the Protection of Surfaces of Materials
IPC: B29C63/00
Filed: 1967-05-12
Abstract: 1,157,364. Laminates. KALLE A.G. 12 May, 1967 [13 May, 1966], No. 22094/67. Heading B5N. A process for protecting material surface by applying thereto a protective film that can be detached therefrom, the protective film comprising a film laminate including an external layer of a thermoplastic material having a melting or softening point lower than any such point of the other layer or layers of the laminate, comprises heating the latter until the external layer fuses or softens and applying the film to the material surface with the fused or softened layer in contact therewith. The difference in softening or melting points of the layers of the film, which may be transparent or include a transparent layer, is at least 20‹ C. Preferably the external layer to be applied to the surface consists of polyethylene and another layer of the film laminate is polypropylene, e.g. biaxially stretched polypropylene film. The other layer may also be constituted by a film of polyester, polyamide, ceullose ether, cellulose ester, polycarbonate, polyvinyl chloride, transparent paper which may be printed or dyed, or aluminium. The external layer may be replaced of polyvinyl acetate or a copolymer of ethylene and vinyl acetate. Heating may be effected by infra-red radiation or hot air, by heating the material surface to be protected or by heating the rollers used to press the protective laminate on to the surface to be protected. The latter may consist of the surfaces of steel or aluminium sheets, pressed plates of melamine resin, plastics coated chip boards and asbestos plates, glass plates, mirrors, marble plates or synthetic plastics films.

Filed: 1937-08-16
Abstract: 491,268. Actuation of switches. HAMILTON, W. R., and HAMILTON, R. W. Aug. 16, 1937, No. 22502. [Class 38 (v)] An electric switch actuated by the flow of a fluid, comprises two contacts, a brass rod 25 partly cut away and a flat steel spring strip 26 carrying an armature 26d, the weight of which causes contact tip 26e to engage with contact 25. These are housed in an insulating tube 23a, lining a metal tube 18 which lies directly below a vane 14a when this is at rest under the sole influence of gravity. In this position a permanent magnet 33 carried by the vane 14a attracts the armature 26d and opens the switch. The vane 14a is caused to move by fluid pressure in the direction of the arrow about pivots 15a, and the magnet 33 moves away from the switch which therefore closes, thus operating an alarm.

Title: Improvements in or relating to switches for charging batteries
IPC: H01M10/46
Filed: 1921-08-25
Abstract: 189,227. Webber, A. B., and Standard Time Co., Ltd. Aug. 25, 1921. Electromagnetic switches.-A two-way switch for automatically connecting, for a short period, a small battery to its charging circuit whenever the intermittent load on the battery is taken off, applicable particularly to electrically-controlled clocks, comprises a pair of contact members 17 normally in engagement with the fixed contact 19 to connect the battery to the load through the operating electromagnet of an armature 26 having a hooked spring extension 31. When the load is taken off the battery, the armature rises and the armature extension 31, which in the downwards direction pass idly by an extension 13 of the contact member, engages the extension and moves the contact-member over to the charging position. The movement is slow, owing to a retardation mechanism 42 associated with the gravity controlling-arm 14, and proceeds until the hook springs pass the extension, whereupon the arm begins to return slowly. Towards the end of its return movement the arm begins to drive the contact-member through a spring-plate connection, but the contact-member is retained by the attraction of a permanent magnet until the plate spring is sufficiently strained to ensure a quick switching movement. Automatic means other than electromagnetic may be employed to change over the switch.

Patent GB-1589127-A (GB)
Title: Opening of packaging containers
IPC: B65D5/06
Filed: 1978-05-25
Abstract: A packaging container, which is suitable, for example, for milk, consists of a packaging material which is provided with a plastic coating at least on one side. Provided for forming a removal aperture for the contents are lines of weakness (8) which bound an aperture. At the places (edges, corners, etc.) subjected to greater loading when the packaging material is converted, the material weakening is less than at the other places in order to avoid unintentional tearing-open of the line of weakness and thus the container becoming leaky. The material weakening is differentiated by the different ratio of the effective length of the line of weakness to the length of the intermediate spaces. It has been found, in particular, that, with the same individual lengths of the effective weakening lines and intermediate spaces, the strength with small intermediate spaces is greater than with larger intermediate spaces. <IMAGE>

Abstract: 1353277 Wells &c CAMCO Inc 16 May 1972 [28 Oct 1971] 22962/72 Heading E1F [Also in Division F2] A safety valve 10 located in a tubing string has a chamber 34 filled with fluid, the fluid 'being heated or cooled to control the actuation of the valve. The valve 10, locked in a landing nipple 38 in a string 11, has a flapper 16 held open by a sliding tube 20 and spring urged to close on a seat 14. The chamber 34, formed between the valve body 12 and the tube, is filled with fluid which expands or vaporizes when heated by an electric heating coil 37 housed in the string and connected to the surface. Heating the fluid forces the tube downwardly to open the flapper, and allowing the fluid to cool by switching-off the coil removes the tube from the flapper which closes under the action of the spring and well fluid pressure. The coil may be replaced by a steam heated one. In a modification the tube is held in its uppermost position by the pressure of the fluid which is at well temperature so that the flapper is closed. Cooling fluid supplied from the surface reduces the fluid pressure and the spring moves the tube downwardly to open the flapper.
