Title: Apparatus for locating and for Raising Sunken Vessels.
Inventor: BEARD HIRAM EDMOND
IPC: B63G8/41
Filed: 1916-10-12
Abstract: 111,687. Beard, H. E. Oct. 12, 1916. Sunken ships, raising.- In apparatus for locating and raising sunken ships, in which a buoy released from the ship rises to the surface of the water and lifts a cable connected to the ship, and grappling means are lowered down the cable to engage a hook on the ship, the hook member 20 has a mushroom head 55, is attached to the ship by a double pivot 18, and contains a reel for the cable 53 which is connected to the indicating buoy 15. The chamber 52 for the reel is narrow to prevent back lash. The buoy 15 is so shaped as to offer little resistance in its passage through the water and has a recess 19 in its under side 21 to house the hook 20. A conductor in the cable 53 is connected to a conductor 67 passing into the ship for purposes of communication, the water forming the return conductor. When the buoy is found, the cable 53 is attached to the slack cable take-up device 53<1> on a salvage ship and grappling means, connected to a lifting- rope 89 and comprising a frame 81 and hooks 83 limited in movement by abutments 84, are lowered down the cable 53 to engage the mushroom head 55, latches 93 then locking the parts. The grappling means have a mushroom head 88 so that, if the first lifting-rope breaks, further grappling means may be lowered to engage the first grappling means. The mushroom heads 55, 88 are radially grooved.

Title: Thermoplastic moulding compositions
Inventor: FENDLEY JOHN ATTON
Filed: 1957-05-08
Abstract: Thermoplastic moulding compositions comprise 50 to 90% by weight of a hard non-rubbery polymer obtained by polymerizing methyl methacrylate with 0 to 25% of its weight of acrylonitrile, and 50 to 10% of a rubbery polymer or copolymer of butadiene-1,3 having a gel content of at least 30% by weight, that is insoluble in methyl ethyl ketone after extraction for 24 hours at 20 DEG  C. Specified rubbery copolymers are those of butadiene with styrene, acrylonitrile, methacrylonitrile and methyl methacrylate, optionally with a cross-linking agent, e.g. divinyl benzene.  They may be prepared by polymerization in aqueous emulsion in the presence of emulsifying agents, e.g. sodium lauryl sulphate, sodium oleyl sulphate, sodium cetyl sulphate, the sodium salts of sulphonated castor oil or of sulphonated or sulphated methyl oleate, sodium oleate, sodium palmitate or sodium stearate, catalysts, e.g. hydrogen peroxide, potassium persulphate or redox systems, and modifiers, e.g. mercaptans, organic polysulphides and dialkyl xanthogen disulphides. The gel content may be increased by polymerizing to high conversion, e.g. greater than 75%, or by milling the polymer.  The methyl methacrylate polymer may be prepared by polymerization in aqueous emulsion or by a granular process in the presence of a suspending agent, e.g. gelatine, pectin, starch, methyl cellulose, hydroxyethyl cellulose, talc, kaolin, polyvinyl alcohol or salts or polyacrylic or polymethacrylic acids, and catalysts, e.g. benzoyl peroxide. The polymers may be mixed by mixing aqueous dispersions before coagulating or spray drying, by adding one in dry powder form to an aqueous dispersion of the other and thereafter separating the water, or masticating the dry polymers.  Pigments, fillers and lubricants may be added and the compositions may be vulcanized. The compositions may be formed into extruded pipes, pipe couplings, refrigerator parts, kick panels, protective helmets, wheels, gears, pulleys and combs.

Title: Method of manufacturing coloured oriented articles from acrylonitrile polymers and copolymers
IPC: D06P1/673
Filed: 1961-04-25
Abstract: 986,114. Dyed polyacrylonitrile fibres. A. STOY, and M. SIVOKOVA. April 25, 1961 [April 25, 1960], No. 14848/61. Heading B5B. Dyed oriented home- or co-polyacrylonitrile articles such as fibres are made by shaping a gel of 15-35% of the polymer and 65-85% of an inorganic salt solution, stretching the product 200-900%, washing, dyeing, and setting the polymer structure. Dyeing must be effected within a limited time of washing dependent on the degree of stretch. A single solution may effect both washing and dyeing. The acrylonitrile may be co-polymerized with vinyl acetate or pyridine, styrene, or methyl methacrylate. The inorganic salt may be sodium or potassium thiocyanate, zinc chloride, or lithium bromide, alone or together with calcium or magnesium chloride or aluminium nitrate. The solvent for the inorganic salt may be water and/or methanol or ethanol. Polymerization may be effected in the inorganic salt solution. The gel may be formed as a moulded layer (which is then cut into strips), moulded monofilaments, or spun yarn. Washing before dyeing may be effected in dilute hydrochloric acid solution. Practically any dyestuff may be used, for example an acid dyestuff containing one or more sulphonic acid groups. Stretching may be effected in a hot dyeing bath. The dyed article may be washed with water, dried at 60-90‹ C., and set at 125‹ C. Examples are given.

Title: Improvements in or relating to radioactive organic compounds
IPC: G01N33/62
Filed: 1959-05-01
Abstract: The urea content of body fluids, especially blood from which the serum has been removed, is determined by adding radio-active xanthydrol having a C14 atom in the 9-position (see Group XL(a) ) in order to precipitate dixanthyl urea, separating and washing the precipitate, and measuring its radio-activity.ALSO:Radioactive o-phenoxy benzoic acid having a C14 atom in the COOH group is prepared by reacting gaseous carbon dioxide p  containing C14 with o-phenoxy phenyl magnesium iodide.  The acid is converted to xanthone having a C14 atom in the 9-position by the action of acetyl chloride at an elevated temperature in the presence of sulphuric acid. Reduction of the xanthone using aluminium powder and potassium hydroxide solution yields radioactive xanthydrol which is used to estimate urea in body fluids by precipitation of dixanthyl urea.

Abstract: 496,940. Thermal switches; snapaction switches. TUCKER & CO., Ltd., J. H., FUKE, F. C., and AVISON, R. G. June 3, 1937, No. 15385. [Class 38 (v)] A safety switch for electrically heated vessels comprises a frame-plate attachable to the casing bearing a sliding rod carrying contacts, and adapted to be pulled to set the switch and to set toggle members and rod in alignment in which position they are held slightly over centre by a spring operating to one side of them, the same spring also acting to reinforce the breaking of the toggle, after the initial movement has been effected by a thermal element on overheating. In the Figure, which shows the switch in the " on " position, the toggle members l, m and the sliding resetting rod f are in substantial alignment, retained by the spring o, the bridging contacts b, d being closed. In this example the switch is held in this position against jar by an additional three-armed lever r pivoted at s, a catch r<5> on the arm r<3> being engaged under a terminal piece m<1> on an extension of toggle arm m, through a spring w. On overheating, the rod t, normally held as by solder, rises owing to the pull of spring w, forcing upward a plate r<4> on the arm r<1> of the lever r, the rotation of the lever giving a positive start to the breaking of the toggle. The rod f may be operated by a handle i, or, if mounted vertically, by a pedal. According to the Provisional Specification the switch may be operated by movement of the pan bottom on overheating.
