Abstract: 1375873 Preventing theft from shops CHECK MATE SYSTEMS Inc 2 Feb 1972 [3 Feb 1971] 4806/72 Heading A4T [Also in Divisions B8 and G4] Thefts of products from a shop are prevented and sales records obtained by means of an electrically releasable device, as shown, which is secured to each product, is readily detected by detection apparatus near the shop exits, can be released by application of an electrically powered key 20, and can contain data relating to the product which are read-out automatically in the form of electrical signals when the key is applied to unlock the device. The unlocking is produced by heating a bi-metallic element within the device with an electric current supplied by the key. The device may have two pivotally connected parts 34 and 36, biased to an open position limited by pin and slot 140, 142. The device may be secured around one part of the product e.g. the handle 32 of an electric iron, or one part may be formed with points (48a), Fig. 3, (not shown) which pierce a part of the article or its wrapper and are received in the other part. The data may be encoded on a card or the like which has an aperture to fit over boss 64, and be retained by the device when it is locked. The coding may be magnetic or optical. The card may also have a part projecting from the device which carries written information about the product. The two parts may be connected along a perforated line, so that the card tears rather than pulls out of the device. The encoded data is preferably read by the key as it moves along a keyway in the device towards the position in which it unlocks the device, magnet 44 within the device is detected to give the alarm if the device is taken out of an exit to the shop.

Filed: 1918-03-21
Abstract: 121,452. Rialland (nÚe Percevault), A. Dec. 10, 1917, [Convention date]. Recovering waste lubricants.-Waste lubricants are purified e.g. from suspended solids or from dissolved salts of copper, tin, lead, or other metals, by mixing with a tannin-gelatin alkali solution and slightly acidifying so as to produce a precipitate of tannate of gelatin which carries down the impurities. The mixture is agitated, allowed to settle, and is filtered hot. The tanningelatin solution may be obtained from gelatine or from waste-leather. The Specification as open to inspection under Sect. 91 (3) (a) states that the precipitate may be formed by precipitating a hot alkaline solution of gelatine with a salt of alumina, or iron, or by precipitating a solution of an alkaline tannate with lime or another metallic salt. This subjectmatter does not appear in the Specification as accepted.

Title: An improved pouring appliance for producing artificial skins
IPC: B29C48/08
Filed: 1932-02-19
Abstract: <PICT:0375243/IV/1> <PICT:0375243/IV/2> In the manufacture of artificial skins of material such as cellulose, the slotted pourer pipe, from which the film-forming solution is extruded, is uniformly fed over its whole length by means of a supply pipe provided with graduated choking nozzles which compensate for the fall in solution pressure along the supply pipe.  As shown in the drawings, the pourer pipe is constructed in two halves 1a and 1b which are bolted together. The extrusion slot 11 is adjusted to the required thickness by means of two plate members 2a, 2b secured by screws 3.  One of the two end walls 7 carries the supply pipe 8.  This pipe is closed at one end and is provided with a number of choking nozzles 9 the size of which increases in the direction of flow.  The arrangement of the supply pipe within the pourer pipe disposes of the need for connecting tubes.  For assisting uniformity of flow the nozzles 9 are directed away from the extrusion slot, and the two halves 1a, 1b are provided with longitudinal grooves which together form a duct-like enlargement 14.  The extrusion slot is thus divided into several slots 11, 12, 13 which become narrower towards the actual outlet.

A valve h, suitable for regulating the flow of viscous fluids, is actuated by a piston b, diaphragm, &c., included in the flow path of the regulated fluid and across which is established a differential pressure produced by passing the regulated fluid through a choke tube l, orifice, nozzle, &c., the valve being urged to open by the difference of the forces due to a weight, and to a spring acting on the weight, and to close by the differential pressure. As shown, the weight is constituted by the weight of the piston and the spring c is a tension spring adjustable by the handwheel f and screw e. The spring may be replaced by a compression spring supporting the piston, and part of the weight of the piston may be relieved by a weight at the end of a beam on a movable fulcrum. The valve h is shown as a ball valve actuated through a crank i, but it could be a piston valve. The device for producing the differential pressure may be included in the piston itself. A steam jacket n is employed for use with viscous liquids.
