IPC: G21C7/22
Filed: 1959-11-26
Abstract: 962,311. Reactors. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Nov. 15, 1960 [Nov. 26, 1959], No. 40174/59. Heading G6C. A reactor comprises a nest of vertical tubes which contain liquid moderator. The spaces between the tubes house channels which contain fuel and coolant. Each coolant channel 7 is surrounded by moderator tubes 2. The latter have hexagonal end pieces; they rest at the base on a perforated plate and are held together at the top by a plate 8 with a cut-away centre. The lower plate rests on beams which include channels 18 through which moderator (D 2 O) is withdrawn for cooling; cool moderator is returned to the top of each tube where a baffle 16 distributes it over the walls of the tube and retains some to form a reflector 32. Radiolytic gases are flushed out by He flowing in through tubes 21 perforated above and below the moderator surface and out through tubes 22. The reactor may be controlled and shut down by variation of the moderator level, by control rods 26, or by poisoning e.g. with boric acid. The reactor is steam-cooled. Rapid shut down is affected by dumping of the moderator, dropping of the control rods.

Abstract: 1,212,517. Staying masts. DELL QUAY GROUP Ltd. 29 Aug., 1968 [2 Sept., 1967], No. 40222/67. Heading B7V. Means for staying a mast 2 comprises a spreader member 4 which spreads a stay, a portion of member 4 being engaged within the mast. In Fig. 2, sockets 8 are inserted in opposite holes in the mast and have their ends 10 bolted together so that flanges 12 bear against the outer surface of the mast. The end of the member 4 is inserted into the socket and is then rotated through 90 degrees so that pins 20 engage the rear surfaces of ribs 18. Rotation of the member 4 is then prevented by a stay under tension passing through the free end of the member 4. In Fig. 4, a plug 24 having a longitudinal slot 26 through which the stay 6 passes is inserted into hollow member 4 and retained against rotation by pin 28. In Fig. 5 (not shown) a tube (30) extending through the mast contains a bobbin (34) with heads (42), the stays having reduced portions engaged behind the heads.

Abstract: 1,075,434. Shearing. H. JESPERSEN. Sept. 22, 1965 [Sept. 26, 1964], No. 40365/65. Heading B3W. A tube-shearing device comprises a frame 1 having a tube receiving aperture therein which forms a fixed knife, a movable knife 12 which also has a cutting edge formed by a tube receiving aperture and which is held in contact with the fixed knife by a clamping plate 25, and a guide ring 2 which surrounds the movable knife and which has cams 4, 5, 6 and 7 which co-operate with cams 13, 14, 15 and 16 on the movable knife to produce orbital motion of the knife. The cams 13, 14, 15 and 16 are angularly spaced from each other by 90 degrees, but the angular spacing between the cams 4-5, 5-6 and 6-7 is less than 90 degrees so that the angular space between the cams 7-4 is greater than 90 degrees. In the guide ring are four recesses 8, 9, 10 and 11 which co-operate with the 15, 16, 13 and 14 respectively so that as the guide ring is rotated by a lever 3 to the position 3<SP>1</SP>, shown in dotted lines, the movable knife is displaced radially in several different directions and shears the tube 24. The tube is supported internally by a plug 19 the end face of which is flush with the interface between the fixed knife 1 and the movable knife 12. A further knife 21 is secured to the plug 19 by a bolt 20 which passes through an oversize hole in the knife 21 to allow the knife 21 to move with the tube 24 as it is sheared by the movable knife 12.

Title: Automatic packaging
IPC: B65B11/52
Filed: 1973-08-29
Abstract: 1437726 Packaging M E WALLIS 29 Aug 1973 [31 Aug 1972] 40697/73 Heading B8C [Also in Division B2] Articles are conveyed by a conveyer 12 to intercept a molten sheet or film 13 of plastics material extruded from a head 14 and as the article intercepts the molten sheet 13, a partial vacuum is developed around the article to cause the sheet to wrap and seal about the article. To create the partial vacuum, suction is applied through an elongate orifice 17 having a length at least as great as the width of the extruded sheet 13. As the wrapped article is moved away from the region of the head 14 by a conveyer 16, the suction separates the trailing portion of the extruded sheet from that wrapping the article and also breaks away excess film from the wrapped article. The plastics scrap is drawn into and collected in a perforated basket 28 located in a chamber 24 between the suction orifice 17 and a blower. The scrap may alternatively be gathered and carried away by a conveyer or a vacuum transfer system. Air from the blower is directed through ducting 54 and blown on to the wrapped articles as they are conveyed on a perforated belt conveyer 62. To produce a seal between the molten sheet and the trailing side of an article, the article may be conveyed into the molten sheet in an inclined position so that the trailing side has a somewhat upwardly facing surface. Alternatively the article may be modified and, as disclosed, a tray to be wrapped has a flange 47 extending from its trailing side 44 and to the upper surface of which the molten sheet material seals. The flange 47 includes a line of perforations 48.

Abstract: 1284542 Thermographic stripping films used to produce multi-coloured images AGFA GEVAERT 20 Aug 1969 [3 Sept 1968] 41793/68 Heading G2C A heat-sensitive stripping film comprises a support, a stripping layer of a hydrophilic colloid and glycerol and a heat-sensitive layer which undergoes a change in water permeability on exposure; the adherence of the stripping layer for the support being weakened when wetted with an aqueous liquid, The prepared colloid is gelatine. The invention also relates to a recording process wherein a heatsensitive layer as above carried on a temporary support is transferred by adhesion to a permanent support and then imagewise exposed to heat. The latent image thus produced may be developed by removing the water-permeable areas with an aqueous medium. The temporary support is preferably coated with a stripping film as above and the heatsensitive layer preferably contains a pigment. Specified heat-sensitive materials are those disclosed in Specification 1, 139, 841; 1, 139, 894-5 and 1, 160, 221. In the examples, a subbed permanent polyester support Specification 1, 234, 775 is coated with a heat-sensitive layer of polyethylene particles and a green pigment are dispersed in polyvinylpyrrolidone, imagewise heat exposed to a green separation negative and developed to leave a green positive image. A red heat-sensitive layer on a gelatine stripping layer containing glycerol and a cellulose triacetate temporary support was pressed whilst wet on to the green image and the temporary support stripped off, The red layer is imagewise exposed and developed and a blue heatsensitive layer transferred on to the red image from a temporary support and the process repeated to produce a multi-coloured image. The heatsensitive layer may include a water-soluble dye which absorbs light and converts it to heat so that on flash exposure to light may be used and so that the dye is removed completely from the layer by washing after exposure, Four coloured images are also produced using a black separating negative. The multi-coloured image may be protected by applying a protective layer e.g. as disclosed in Specification 1, 284, 543.
