Filed: 1950-05-17
Abstract: 701,693. Displaying. ANGEHRN, E. R. May 17, 1950, No. 23021/50. Divided out of 701,688. Class 3(2). A display device comprises a back support, a flexible display sheet secured to one end of the support so that.the sheet passes around the said end with a display portion of the sheet extending in front of and towards the other end of the support and means connecting the other end of the sheet to the said other end of the support so that the part of the display portion of the sheet in front of said other end of the support is inwardly bowed towards the back support so that the display sheet is of scroll formation. As shown in Fig. 2, a flexible display sheet 16 is stapled to the top of a strut 15 so as to pass around the top and extend lengthwise of the strut. Part of the sheet is folded to form a base 19, and the end 18 is bent up so that the resilience of the sheet holds the strut against it. In an alternative construction, Fig. 3, the strut is replaced by a rectangular tube 20 which may be collapsed flat. The sheet 23 is stuck to the top of the tube at the rear and the other end of the tube engages a flap 24. With the tube collapsed the device is flat and is erected merely by opening the tube. In another construction the tube is circular in section and is non-collapsible. The sheet engages a slot at the top rear of the tube and has a base and flap to engage the bottom similar to that shown in Fig. 3. In this construction the sheet may be detached from the tube and rolled up for mailing inside the tube. Specification 701,688 is referred to.

Title: Improvements in or relating to filters
Inventor: CLEGG JOSEPH
IPC: B01D37/02
Filed: 1964-06-03
Abstract: 1,104,231. Filters for liquids. POROUS PLASTICS Ltd. 1 June, 1965 [3 June, 1964], No. 23026/64. Heading BID. A filter includes a foraminous tubular reinforcing core formed by sintering a coarsegrained plastics material, and, separate from but fitting closely about the reinforcing core, a tubular filter septum of microporous plastics material. As shown, for a swimming pool filter, a reinforcing core 11 is made by packing coarse grains (themselves microporous) of polyethylene around a mandrel in an iron tube forming a mould. The assembly is heated to sinter the plastics material. The hollow cylindrical core is then removed and fitted into a tubular septum 10 of microporous highdensity polyethylene having one end closed by a disc 12 secured by adhesive and the other end provided with an adhered flange 14 into which a disc of wire gauze 15 is inserted. Several such filter candles are assembled in holes, in a header plate 16, each occupied by a grooved rubber grommet 17. In operation, unfiltered liquid is pumped into casing 20 to flow inwards through the candles, and filtrate flows to use through a pipe (not shown) connected to cover 21. For backwashing, unfiltered liquid is pumped along part of the outlet pipe, including the connection with cover 21. and outwards through the filter candles. This liquid, plus residue, is discharged along part of the inlet pipe and to a drain connection. Appropriate isolating valves are provided. Filter aid such as kieselguhr may be applied. Instead of polyethylene grains, polyvinyl chloride grains may be used for the core 11.
Patent GB-1512024-A (GB)
Title: Recording process
IPC: B41M5/20
Filed: 1975-05-23
Abstract: 1512024 Electrographic printing EASTMAN KODAK CO 23 May 1975 [29 July 1974] 23072/75 Heading B6C An electrographic recording process produces visible images in a charge-sensitive recording element containing a reducible metal compound by subjecting the element to a current in selected regions to produce a storable latent image having a charge density of less than 1 millicoulomb per square centimeter and developing by the application of heat. The charge-sensitive layer of the element incorporates a reducible metal compound, a reducing agent being also included in that layer or in a contacting layer during development, heat activating the reduction reaction. The chargesensitive layer may be sensitive or insensitive to visible light; if it is light-sensitive, then it is possible to superimpose the electrically-produced image and a light-exposed image and develop them simultaneously. It is also possible to transfer the developed image to a thermoplastics receptor sheet. Imaging methods include applying current by a single stylus or selectively from an array of styli; scanning with an electron beam through an electrostaticallycharged stencil; placing a photoconductor 30 in contact with the charge-sensitive layer 10, Fig. 2a, between conductive members 15, 35. Member 35 being transparent, and imagewise exposing while applying a potential from source 40 across the sandwich; the charge-sensitive layer 10 thus receives an imagewise modulated current. If a suitable photoconductor is chosen, it need be exposed only once and used with a plurality of successive recording elements. An alternative method includes applying a potential across a similar sandwich with photoconductor 30 being replaced by a dielectric material with a built-in conductivity pattern. Potential could also be applied using a grid controlled corona charger. Development may be by contacting the recording element with a heated platen, or by passing between heated rollers or by applying radiant heat. It is stated that the imaging method produces electrical and/or chemical change in the sensitive layer, the dry development subsequently causing reduction only in those areas.
Patent GB-852743-A (GB)
Title: Improvements in or relating to a method of manufacturing flat plastic moulded shapes
IPC: B44C5/06
Filed: 1957-07-22
Abstract: Artificial plastic foliage, petals, flowers and the like are made by first preparing a mould with a plurality of cavities of the desired shape, inserting stems into stem channels of each mould cavity, filling the mould cavities with liquid, heat-solidifiable plastic material, e.g. a vinyl base pigmented plastisol, and subjecting the mould to a source of heat until the plastic material solidifies.  The moulds may be stamped from aluminium sheet and preferably anodised black.  It is important that they be preheated before use to bring them to the solidifying temperature of the plastic.  The plastic is extruded into the mould cavity from a nozzle formed from material softer than that of the mould to prevent scratching and is applied in a continuous band around the edge of the cavity and in a central deposit before being brushed to an even level over the entire mould area.  Where contrasting coloured speckles are required on the patterned surface of the foliage, the surface of the mould cavity is stippled with a suitably coloured liquid plastic and heated to a firm set prior to the filling of the cavity, The stems which are inserted after the mould filling operation are cotton-wrapped wires which are heat-dried beforehand.  The moulded products are stripped from the moulds immediately they are solidified by grasping the stems with a stripper block and manually flipping the moulds upwardly with a twisting motion.  The plastic portion of each moulded item is manually twisted immediately after stripping and before cooling to impart a life-like curved appearance to each item.

Abstract: 532,084. Mercury-vapour generators. BRITISH THOMSON-HOUSTON CO., Ltd. Aug. 16, 1939, No. 23642. Convention date, Aug. 17, 1938. [Class 122 (iii)] In a mercury boiler having both natural and forced circulation, mercury from a drum 28, Fig. 1, is forced by a pump 26 into down-tubes 22, 23, which line the walls of a combustion chamber 11 and are connected at their lower ends to up-tubes 36, 37 lining the walls of a convection chamber 13. The tubes 36, 37 are connected to the upper ends of heating-tubes 38, which have hairpin-shaped portions and are located in an extension of the convection chamber. The lower ends of the tubes 38 are connected to the drum. In order to obtain the maximum circulation, means are provided for preventing evaporation in the down-tubes 22, 23 by varying the speed of the pump. The tubes are arranged to be movable vertically in relation to the walls of the boiler, as described in Specification 530,461. The lower portions 14, 45 of the walls have sliding joints with the upper portions, and are supported by the tubes. The tubes are drawn downwards and outwards by springs. In a modification, the combustion chamber, to which fuel is supplied from a burner 58, Fig. 2, is lined with both up-tubes 59 and down-tubes 60, 61, which extend between an upper header 62 and lower headers 63, 64, 65. A convection chamber 57 contains up-tubes 66, connected at their lower ends to the headers 64, 65, and at their upper ends to the drum 67. Mercury liquid is forced from the drum by a pump 70 into the lower header 63 and thence through the up-tubes 59. It then flows down the tubes 60, 61 to the headers 64, 65, and finally up the tubes 66 to the drum. The circulation in the combustion chamber is effected primarily by the pump, and that in the convection chamber primarily by thermo-syphon action. The means for preventing evaporation in the combustion chamber is responsive to pressure-temperature differential, as described in Specification 501,200. Pressure and temperature responsive members act on bellows 73, 74, which jointly operate a lever controlling a switch 77. The speed of the pump-motor 80 is accordingly varied by the insertion or short-circuiting of a resistance 79.
