Title: Improvements in or relating to ships for carrying liquefied gases
IPC: B63B25/16
Filed: 1957-04-26
Abstract: 854,706. Carrying liquefied gas. CONSTOCK LIQUID METHANE CORPORATION. April 26, 1957 [May 7, 1956], No. 5374/59. Divided out of 854,705. Class 113. A ship for the transportation of a liquid cargo which needs to be maintained at a low temperature comprises an outer hull, an inner wall spaced a short distance from the outer hull to form an inner hull which defines a cargo space, cargo tanks 17 in said cargo space, at least one of the tanks having a thermally insulated dome 21 extending upwardly through the deck 28, through which dome the liquid cargo may be loaded and unloaded (via conduits 34, 33), and a thick layer of a thermally insulating material 16 between the tanks and the inner hull. The dome is in the form of a cylinder 26 provided with corrugations 25, has insulation 31, and is braced by a structure 39 against lateral shifting.

Title: Improvements in or relating to tongs for screwing or unscrewing pipe sections
IPC: E21B19/16
Filed: 1948-02-24
Abstract: 652,425. Screwing or unscrewing pipe sections. BYRON JACKSON CO. Feb. 24, 1948, No. 5457. Convention date, Dec. 30, 1947. [Class 83 (iii)] A tong for screwing or unscrewing pipe sections comprises a lever 11 having a series of pivotally - interconnected jaws 13, 14, and 17, the jaws 13, 14 being pivotally connected to the lever at spaced points 15, 16 so that swinging of the lever in one direction constricts the jaws about a pipe 21, and rollers 24, 26 for rotating the pipe relative to the tong which are mounted on the jaws 13, 14 respectively, so as to be movable to engage or disengage the pipe. The jaws 13, 14 are provided with gripping dies 22, 23 respectively. Rotatable idler rollers 49, 50 are mounted on the jaw 17. The rollers 24, 26, 49, 50 are advanced to engage the pipe by fluid-pressure means comprising roller supports connected to the pistons of piston- and-cylinder assemblies 35, 45 and 54, which are connected to a source of pressure fluid 95 by means of conduits 108, 109 controlled by a valve 105, and are retracted by means of springs. The rollers 24, 26 are rotated by means of sprockets and chains driven from a sprocket 61 driven by an air motor 57. The jaws 13, 17 are releasably connected together by means of a latch 19 which is moved to the closed position by a spring and to the open position by a piston-and-cylinder assembly 117 operated by the air motor 57. When screwing- up a joint, the rollers 24, 26, 49, 50 are advanced to engage the pipe by operating the valve 105 to connect a supply conduit 103 to the conduits 108, 109 leading to the cylinders 35, 45, and 54, and a valve 90 is opened to actuate the motor 57 to rotate the rollers 24, 26 in a counterclockwise direction. The pipe is thus rotated in a clockwise direction and the turning movement of the pipe is continued until the motor 57 stalls under overload. The valve 90 is then closed and the valve 105 operated to connect the conduits 108, 109 to a return conduit 102. The rollers 24, 26, 49, 50 are then retracted by means of the springs provided, A.tong line 128 secured to the outer end of the lever 11 is then tensioned to swing the lever in a clockwise direction constricting the jaws 13, 14, and 17 about the pipe and bringing the dies 22, 23 into engagement therewith. Continued tensioning of the line 128 applies the final screwing action to the pipe. To remove the tong from the pipe, the line 128 is slackened to release the grip of the jaws on the pipe. Air is then admitted to the latch-operating cylinder 117 thereby causing the latch 19 to be swung outwardly from engagement with the jaw 17. In a modification, the idler rollers are fixed in position. In another modification, only one roller for rotating the pipe is provided. In a further modification, one of the jaws is provided with two gripping dies.

The liquid may be an aqueous solution of non-ionic sugar, e.g. sucrose, or a macromolecular solute, e.g. a copolymer of sucrose and epichlorohydrin, or dextran, of molecular weight 10,000-2,000,000. The fluid may be a body fluid e.g. blood, bone marrow, spinal fluid, pleural fluid, or urine. The liquid may be separated, mixed, and plated out on a nutrient medium for microscopic analysis. In a modification, a gelling agent is added to the liquid in a centrifuge tube, which is then cooled to solidify the liquid, then the fluid is added and the tube warmed to liquefy the gel for centrifuging. The gelling agent may be gelatine. A device for use in the method comprises a tube closed by means allowing passage of a hypodermic needle and containing a sterile aqueous solution for reception of the micro organisms, the aqueous solution comprising less then 50 weight per cent of a gelling agent, which may be an epichlorhydrinsucrose polymer or a dextran.

Patent GB-355302-A (GB)
Title: Improved process for obtaining iron from iron carbonyl
IPC: C22B5/20
Filed: 1930-02-22
Abstract: Iron is obtained mainly in the form of leaflets or lamin  by introducing heated small inorganic non-metallic bodies, e.g. spheres, cylinders, &c., of quartz, quartz glass, natural or artificial corundum, glass or porcelain, into a space filled with iron carbonyl vapour and then separating the deposited iron from the bodies.  The apparatus used may comprise a central chamber filled with carbonyl vapour, a feed chamber into which the heated bodies are charged from charging cylinders with hinged bottoms and from which they are fed into the central chamber either by gravity or by means of a conveyer, and cooling chambers leading from the central chamber.  The air is displaced from the charging cylinders by carbon monoxide before the bodies are charged into the feed chamber and the carbon monoxide resulting from the carbonyl decomposition passes down the cooling chambers and prevents the access of air until the iron is cooled. The iron may be separated from the bodies by various means, e.g. mechanical agitation, centrifuging, e.g. on the surface of a hollow cone, wind sifting, magnetic or chemical action or a combination of these methods. Carbonyl vapour direct from a carbonyl producer, i.e. mixed with carbon monoxide, nitrogen and hydrogen, may be used. Reference has been directed by the Comptroller to Specification 114,025, [Class 72, Iron &c.].
