Title: Improvements in and relating to liquefied gas storage and dispensing apparatus
IPC: F17C3/08
Filed: 1961-06-02
Abstract: 924,755. Storing liquefied gas. UNION CARBIDE CORPORATION. June 2, 1961 [June 9, 1960], No. 19917/61. Class 8(2). An apparatus for storing and dispensing liquefied gas comprises an inner vessel 10 surrounded by an outer shell 15 within which the vessel 10 is supported by two axially aligned cylinders 20, 21 each extending across an insulation space 18 between the vessel 10 and the shell 15 and having one end disposed in a socket 22 or 23 and the other end disposed within one of the ends of a metal tube 26. The insulation space 18 is preferably subject to a low vacuum pressure and filled with insulating powder of small particle size and containing a pacifying material in the form of metal flakes. Alternatively, the space 18 may be filled with multiple alternate layers of fibre mat and polished metal foil wrapped about the inner vessel 10. The cylinder 20 is fixed in the socket 22 and the adjacent end of the tube 26, the other cylinder 21 not being so fixed to allow for expansion and contraction. The cylinders 20 and 21 are preferably made from reinforced plastic material, e.g. a glass reinforced epoxy resin. The tube 26 is filled with an absorbent material such as silica gel or certain molecular sieve calcium zeolites retained by screens 35 and in communication with the insulation space 18 through holes 29 in the cylinders 20 and 21, for example, so that when subject to the stored gas temperature the absorbent material will absorb traces of gas or vapours from the insulation space. Conduits 30 and 32 are provided for filling and emptying the vessel 10, the conduits being coiled or looped within the insulation space 18 to reduce heat conduction along the conduits. The cylinders 20, 21 may be filled with porous insulating material such as glass wool, glass fibre packing or alternate disks of metal foil and glass fibre mat. The outer shell 15 is mounted on a skid frame 37 connected to the shell through rubber shock mountings 40. The inner vessel and outer shell may be spherical. In a second embodiment, Fig. 3, an inner vessel 110 is supported within an outer shell 115 by cylinders 120, 121. The cylinder 120 has one end secured in a socket 122 provided with a removable cover 50 for renewing absorbent material 127 which is contained in a tubular chamber 54, the latter being welded to a tube 51 within which is secured the other end of the cylinder 120. The cylinder 121 has one end secured in a socket 123 and the other end slidably carried in a tube 60 through which pass filling and emptying conduits 65, 66. The outer shell 115 is mounted on a wheeled carriage. Liquid gas is normally delivered from the vessel 10 under its own vapour pressure but the gas may be put under pressure by external means, e.g. a supply of the same gas as that being stored.

Patent GB-1113722-A (GB)
Title: Aerobically polymerisable compositions
IPC: A61K6/884
Filed: 1965-05-12
Abstract: Compositions which are aerobically polymerizable in the presence of a free radical catalyst comprise one or more mono- and/or bisacrylate or methacrylate monomers and 0.05-6% by weight of the monomer(s) of a triarylborane complex of the formula R3B-Am in which R represents an aryl radical of 6-12 carbon atoms and Am represents sodium hydroxide, ammonia, benzene or an amine.  The radical R is preferably free from hydroxyl, carboxyl and amino groups but may contain substituents such as halo, alkyl and alkoxy groups.  The (meth)acrylate monomer is one which normally polymerizes only with difficulty with a free radical catalyst unless oxygen is almost completely absent; suitable esters are alkyl, allyl and fusel oil (meth)acrylates, the bisesters of glycols and bisphenols, and the bisester condensation products of phenols and glycidyl(meth)acrylate (which may contain additional ethylenic unsaturation).  The composition may also include an oxirane-type monomer, e.g. glycidyl acrylate or methacrylate or a diluent monomer such as phenyl acrylate, hydroxyethyl methacrylate or acrylonitrile.  A free base may also be included as a co-catalyst component, e.g. dimethyl-p-toluidine, tri-nbutylamine, diethylenetriamine, N-methylpiperidine, N-methylmorpholine, 2,5-dimethylpiperazine or 1,2,4-trimethylpiperazine.  Other optional components include solvents, fillers (e.g. silica, alumina or synthetic fluorapatite), pigments, dyes and plasticizers.  To effect polymerization a free radical catalyst is added, e.g. benzoyl peroxide, methyl ethyl ketone peroxide, t-butyl hydroperoxide or azobisisobutyronitrile, and the composition is then activated by heating or acidifying, e.g. with an inorganic or organic acid; the latter is preferably a compound which will copolymerize with the (meth)acrylate monomer, e.g. acrylic, methacrylic, maleic or citraconic acid.  The compositions may be stored as multi-component kit, each component containing some of the ingredients of the composition in stable form.  The compositions are suitable for coating, moulding, potting, embedding or sealing and, particularly, for use as a vehicle in dental filling compositions, as described in Specification 1,113,723.

Abstract: 980,815. Parenteral liquid injection apparatus. W. R. KOEHN. June 8, 1961 [June 8, 1960], No. 20718/61. Heading A5R. [Also in Division G1] Parenteral liquid injection apparatus comprises a parenteral liquid container 10, a flow rate indicator 15, flow control means 18 and means for connection to a patient, the flow rate indicator comprising a float chamber 20 having a continuous downwardly diverging wall and, in the chamber, a float 30 of specific gravity less than that of the parenteral liquid to be metered. A parenteral solution container 10 has an air inlet tube 13 and is connected to an injection needle 17 by a flow meter 15, a drip chamber 24 of flexible synthetic plastic, e.g. polyvinyl plastic, and flexible tubing 16. A clamp 18 on the tubing enables the rate of flow of the liquid to be varied. The flow meter comprises a tapering float chamber 20 of transparent acrylic plastic having a scale. A pointed neck 23 at the upper narrower end of the float chamber penetrates the container stopper 12. When liquid from the container is flowing through the float chamber, the float 30 is held in an equilibrium position by the drag force due to flow of the liquid and a balancing opposing buoyant force due to the difference in the specific gravities of the liquid and the float, the equilibrium position giving an indication of the rate of flow on the scale. The specific gravity of the float is chosen so that a single calibrated scale may be used to indicate the rate of flow of any one of a group of liquids of differing specific gravities in which the drop force on the float is proportional to the specific gravity, e.g. a group including 1% to 20% by weight dextrose solutions, normal saline solutions and other solutions of dissolved salts normally occuring in the body or a group including bloods of differing specific gravities or a group of oils. A flow meter intended for use with blood has diametrically opposite transparent radial fins (not shown) which project into the float chamber to form a guide for the float, the position of the float in the opaque liquid being observed through the fins.
