Title: Improvements in or relating to containers for radioactive or like substances
IPC: G21F5/02
Filed: 1952-06-21
Abstract: 723,814. Housings for radio-active sources of radiation. GILKS, E. -N., and GAMMA RAYS, Ltd. June 21, 1952, No. 16701/62. Addition to 711,532. Class 98 (1). A container for radioactive material of the kind comprising a block of material impervious to radiation with a removable plug includes a plug supporting and guiding structure establishing a predetermined path for the plug between its closed and open positions, in the latter of which the plug is displaced to one side of the path of radiation, and actuating mechanism with a single operating member stationarily situated out of the path of radiation and mounted for turning movement about an axis to move the plug along its path. From another aspect, the mechanism establishes a conversion as between the mode of movement of the operating member and that of the plug, the operating member remaining in or substantially in a fixed location in relation to the body of the container and out of the path of the radiation whilst operated, and serving to move the plug along a path having components extending both parallel and perpendicular to the general direction of the path of radiation. As shown in Fig. 1, and in plan in Fig. 2, the carriage has a U-shaped base resting on wheels 13 and a foot 17, and supports the container 19 on similarly curved arms 18. A socket 14 may receive a handle. Stub shafts fixed on opposite sides of the container are journalled on arms 18. The container may be tilted by a handle 33 on a shaft 31 having a worm wheel engaging a pinion fast on one of the stub shafts. The container 19 has a hollow body, Fig. 3, containing a block 38 of lead or similar dense material. A capsule 43 containing the radioactive material is fixed to a stem 44 slidable in a guide tube 45 in a bore in the block 38. The bore leads into an opening of stepped frusto-conical shape, which is normally closed by a plug 47. A screw-threaded portion 40 of the body can be removed for insertion or adjustment of the stem 44. Plug 47 is supported on an arm 50, Figs. 1 and 2, connected to a cross-head 52 fixed to bars 55, 56 sliding in a housing 61. Bar 55 has rack teeth, Fig. 4, engaging a pinion 69, and bar 56 carries at its free end a roller 62 movable in a cam track 63 formed in a plate 64 fast with the container 19. A hand wheel 74 drives, through worm gearing, the pinion 69, so that plug 47 is first moved out of its seating, and then, through action of roller 62 and cam track 63, is moved into the position indicated at 67 in Fig. 1, permitting the emission of radiation from the container. A key-operated cylinder-type lock 77, Fig. 2, is provided in housing 61 to lock hand wheel 74. A similar lack 83, Fig. 3, locks the removable portion 40 in position. The stem 44 may be locked in position by an eccentric cam 88 entering a slot in sleeve 45 and operated by a lever 89, which is only accessible when the portion 40 has been removed.

Title: Improvements in or relating to apparatus for welding tests
IPC: G01N33/20
Filed: 1961-05-03
Abstract: 918,410. Arc heating electrode holders. MULLER, J. May 3, 1961 [May 3, 1960], No. 16053/61. Class 39 (3). Apparatus which contains an adjustable electrode can be stood on a metal surface, to provide an arc of predetermined current and duration between the electrode and metal, whereby the suitability of the metal for welding may be determined from examination of the resolidified metal. The carbon or tungsten electrode j is connected to the output of a welding- machine via plug b, copper strip e, a pair of bimetallic strips d and d<SP>1</SP> joined at the top by bridge e, copper disc f, brush g, and electrode holder h. The latter is rigidly connected by insulator k to member I which is engaged by a screw-thread with tube m, itself joined to insulating tube n. The latter is seated in the insulating cup o, whereby the axially displaceable structure j, h, k, I, which is pressed down until j contacts the metal specimen 2 to strike an arc, is urged upwards by spring p until the top of tube m abuts latch roller q. For the latter condition, the distance of the electrode from the metal, and hence the arc current, is adjustable by rotation of the structure I, k, h, j with respect to the tube m, corresponding rotation of which is prevented by the engagement of a pin t in a longitudinal slot; the distance is indicated by the co-operation of the clampable sleeve u with a micrometer scale on sleeve v. The duration of the arc is determined by the setting of the stop w on the ammeter scale x, which determines the deformation of the bimetallic strips d, d<SP>1</SP> required to displace the latch roller q and thereby allow the electrode to spring back from the metal a distance sufficient to extinguish the arc.

Title: Method of joining the ends of fibrous mats and a joint produced by this method
IPC: D04H1/66
Filed: 1966-04-12
Abstract: 1,081,159. Scanning non-metallic sheet material. W. H. W. SCHULLER. April 12, 1966 [April 22, 1965] , No. 16076/66. Heading B5K. The ends of fibrous mats B, B<SP>1</SP> are joined by means of adhesive applied only at distributed intervals A to the ends of the mats to be joined. The mats may be of glass fibres reinforced with continuous strands or glass fibre slivers G. The seam may be an overlap seam, as shown, or a butt seam. The adhesive may be based on thermosetting condensation products which have short setting periods and its viscosity may be adjusted by the addition of a filler, e.g. swelling starch, methyl cellulose or diatomaceous earth. Adhesives dissolved in a volatile medium and setting in the absence of heat may be used. The adhesive is applied in the form of dots A, D which may be rectangular, circular, angular, triangular or cruciform and which occupy up to 35% of the area of the joint. Alternatively, the adhesive is applied in narrow continuous or discontinuous lines. At the edges E, F of the overlap the dots D are slightly larger than the remaining dots A or, alternatively, the dots D may be provided in the form of rectangular applications or narrow lines. The dots may be applied by spraying, by brushing using a stencil, by dropping from a container provided above the joint to be produced or by stamping using a hollow stamping strip or stamping roller guided at both ends in vertical rails and containing adhesive which issues through individual nozzles. The period of discharge of the adhesive may be controlled by a time relay. To apply the adhesive, the mats B, B<SP>1</SP> are clamped in position by jaws and the top mat B is folded back to enable the adhesive dots to be applied. The upper mat B is then returned. If the adhesive is applied using compressed air, then it is not necessary to turn the mat B back prior to the application of adhesive since it will permeate the overlap. A pneumatically operated heated bar is lowered to press the joint. The bar is preferably made of individual spring-loaded segments. To form a butt joint, a strip is unwound from a roll, provided with dots of adhesive externally of, or above, the mat, and then moved under or on to the joint.

Abstract: 602,805. Refrigeration; heat-exchange apparatus. SERVEL, Inc. June 26, 1945, No. 16323. Convention date, Sept. 19, 1941. [Classes 29 and 64(iii)] Heat transfer members of absorption refrigerating systems in which liquid flows by gravity over part of a wall, e.g. of a tube 26, have a capillary surface forming an integral part of the wall and extending upwardly from the surface of the liquid. As shown the inside surfaces of the tubes 26 of the evaporator 12 are cut with a fine helical groove swaged to form inwardly extending inclined lips 51, the cut being made at a very acute angle so that liquid is drawn upwardly over the surface of the tubes. The tubes are arranged nearly horizontal so that the liquid flow is along the extreme bottoms of the tubes. The invention is shown applied to a system operated under a vacuum, boiler 10 being charged with a solution of lithium chloride or lithium bromide and heated by steam supplied through a conduit 20 and the expelled water vapour passes from the upper ends of tubes 16 to a condenser 11 and thence through a U-tube 24 to a flash chamber 25 and the evaporator 12. The liquid refrigerant passes into successively lower banks of the finned evaporator tubes 26 through end connections 29 which are open to permit escape of vapour to end headers 30 communicating with the absorber 14. Flash vapour formed in the chamber 25 passes through conduit 31 into one of the headers 30. The absorber and condenser are cooled by water supplied at 45 passing through tubes 34 in the absorber and through a pipe 48 to the condenser from which the cooling water leaves through pipe 49. Weak liquor from the boiler passes through conduit 43, liquid heat exchanger 39, and conduit 32 to a liquid distributor 33, 35, 36, 37 at the top of the absorber and drips over the tubes 34. The strong solution flows through conduit 38, liquid heat exchanger 39 and pipe 40 to a vessel 41 and thence by pipe 42 to the bottom space 17 of the boiler. The pressure in the vessel 41 is equalised with that in the top of the boiler by a pipe 44. Air to be cooled passes over the outer surfaces of the evaporator tubes 26.

Patent GB-219011-A (GB)
IPC: B63C7/12
Filed: 1924-07-10
Abstract: 219,011. Kiwull, W. July 14, 1923, [Convention date]. Sunken ships, raising.-Sunken ships are raised by producing ice locally so as to close the aperture therein, or by means of lifting pontoons frozen on to the ship. Apertures in the deck or outer skin are closed by the local formation of ice which is solidly attached to the surrounding metal parts by cooling the latter by direct contact with pipes or other hollow members through which the refrigerating medium is circulated. Heat insulating layers are used to localize and regulate the ice formation. The apparatus comprises distribution tanks adapted to rest on the surface of the ship and flexible pipes adapted to be spread over the deck or hull to produce the ice coating where required. The method may be used to secure lifting pontoons to the ship by freezing them on. Access to the interior of the hull may be obtained by freezing the water in a compartment into a solid block and cutting shafts in the ice in communication with the air. A working buoy 1, Fig. 3, comprising, a chamber 2 and an outer casing 3 which encloses a trimming tank, is hauled down to the ship on anchored hawsers. The working chamber 2 is connected to the salvage ship by means of flexible piping 4, and is provided with a searchlight, a grab having scissors 5 for clearing, and a pump with jets 6 for scouring sand, weeds &c. Pipes are lowered from the salvage vessel connected to distribution tanks 10, flexible pipes 11 and insulated refrigerating pipes 12. The flexible pipes 11 are spread by operators in the buoy over the deck of the ship and over the damaged parts of the outer skin. Freezing mixture is then pumped through the pipes, producing a layer of ice so that the hull is completely closed. The water in the ship can then be pumped out. Alternatively, vessels 22, Fig. 4, enclosed with layers 23 of heat insulating material and filled with liqud air 20 or cooled by liquid carbon dioxide from cylinders 21 may be used. Lifting means such as pontoons 26 may be provided so arranged that the evaporated air or carbon dioxide passes into them to produce the buoyancy for raising the ship. Pontoons 30, Fig. 5, may be provided with refrigerating pipes 31 and frozen on to the ship by freezing medium supplied through pipes and tanks 33. Specification 183,536 is referred to.
