Title: Method of recovering metal constituents from the grinding swarf of high-grade metals and alloys
IPC: C22B9/18
Filed: 1975-04-28
Abstract: 1469055 Electroslag remelting; making ingots LEYBOLD - HERAEUS - VERWALTUNG GmbH and VACUUMSCHMELZE GmbH 28 April 1975 [22 May 1974] 17637/75 Headings B3F and B3A [Also in Divisions C7 and H5] Grinding-swarf containing, e.g. Ni, Co, W, Cr, Mo, Ti, and/or Nb is compacted to form a consumable electrode 1 which is remelted in a mould 12 to form an ingot 18 containing the desired metals. The compacting may be by isostatic pressure in a cylindrical or prismatic thermoplastic container, or conventionally, with binders. The electrode preferably has a pin 35 embedded in an end to facilitate attachment to an electrode holder 3. The electrode 1 is melted by passing a current to the electrode and to either the mould wall 13 or floor 19, both water-cooled, in the presence of a liquid slag 16. Permanent electrodes may also be used, for temperature control, and ordinary alloy electrodes, to modify the ingot composition. The electrode holder 3 is moved axially of a column 4 as the melting proceeds (controlled by a unit 30 acting on a motor 11). The unit 30 responds to voltage drop through the slag 16 and superimposed pulses. An electronic processor applies signals to the motor 11. 1-10% Of an oxygen getter, e.g. Al, may be added to the swarf prior to compaction.

Title: Improvements in or relating to the production of non-metallic moulded bodies
Inventor: KIDD FREDERICK
IPC: B29C33/12
Filed: 1957-07-05
Abstract: Discarded fibre reinforced plastic elastomeric material, e.g motor tyres or polyvinyl chloride conveyer belting, is cut up and a predetermined quantity of the pieces of which one or more are of large size in relation to the others compressed and heated in a mould so as to be adhesively secured together to form the moulded body required, e.g. a wheel or roller.  The pieces comprise pellets of such small size as to be randomly orientated and one or more large pieces, e.g. discs, which are mounted in a predetermined position as on a core the pellets being introduced around the discs.  The heat may be applied directly to the mould, but in the case of articles of relatively thick cross-section it is preferable to heat the pieces before introduction into the mould and if necessary also to heat the mould.  When rubber is used, the pieces may first be coated with liquid rubber or rubber solution and in the case of polyvinyl chloride with polyvinyl chloride paste.  The ratio of coating material to fibre reinforced material is from 1 : 4 to 1 : 8.  An insert, e.g. a nylon bearing bush, may be mounted in the mould cavity and have keying formations whereby it becomes secured to the body produced.
Patent GB-923192-A (GB)
Title: Process for the production of high molecular weight linear polycarbonates
IPC: C08G64/14
Filed: 1961-05-16
Abstract: Polycarbonates are made by a continuous process by reacting an organic dihydroxy compound with phosgene and/or a bis-chlorocarbonic acid ester of an organic dihydroxy compound in the presence of an organic monohydroxy compound, an acid-binding agent, a tertiary amine of a quaternary ammonium compound (as catalyst) and an inert solvent which dissolves the polycarbonate. A reducing agent may also be present.  The process may be effected in four or five vessels connected in series and each provided with stirrers and the catalyst may be added to the second or third vessel.  Alternatively, it may be effected in a vertical reaction tube fed at the top with a solution of the dihydroxy compound in part of the acid-binding agent, the monohydric compound and part of the phosgene, at four intermediate points with additional phosgene, and at a lower intermediate point with the catalyst and further acid-binding agent.  The polycarbonate solutions produced by the process may be separated from the reaction mixture by a liquid centrifuge and continuously washed and, if desired, dyestuffs pigments or stabilizers may be added.  The solvent may then be removed from the polycarbonate by evaporation in a worm press or by steam distillation.  Alternatively, the polycarbonate may be precipitated by the addition of a non-solvent (e.g. an aliphatic hydrocarbon, alcohol or ketone).  The dihydroxy compound may be a dihydric phenol (e.g. a bis-phenol, or a dihydroxy benzene, naphthalene, diphenyl or quinoline), a phenol alcohol, an aliphatic dihydric alcohol (e.g. an alkylene-, oxyalkylene or thioalkylene glycol), a cycloaliphatic dihydric alcohol or an aromatic dihydric alcohol.  The organic monohydroxy compound may be phenol, a cresol, p-isopropyl phenol, p-tertiary-butyl phenol or p-chlorophenol.  The acid-binding agent is preferably an aqueous solution of sodium hydroxide but a tertiary amine may also be used.  The organic solvent may be methylene chloride, chloroform, ethylene chloride, chlorobenzene, benzene, toluene or xylene.  Examples describe the production of the polycarbonate of bis-phenol A chain-stopped with p-tert.-butyl phenol. Specifications 772,627, 808,485, 808,486 and 808,490 are referred to.

Title: Improvements in or relating to radiation monitors
Inventor: BISBY HARRY
IPC: G01T7/02
Filed: 1962-05-10
Abstract: 984,240. Radio-active liquid monitoring. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. May 1, 1963 [May 10, 1962], No. 17937/62. Heading G1A. Apparatus for measuring alpha radiation from a liquid 7 comprises an alpha radiation monitor 1 and a cell for the liquid, characterized in that a protective film 20 is interposed between the liquid and an alpha radiation detecting screen 19 of the monitor to prevent liquid droplets being deposited on and thus contaminating the detecting screen 19. In the arrangement shown the liquid flows into the apparatus through a pipe 8 and a separator 4 removes undesirable material from the liquid which then flows into a flat cell 2 through an air-bubble trap formed by a bar 28 an underflow weir 29 and a cowl 30. Laminar flow of the liquid across the cell 2 is achieved by a V-notched weir 5 at the outlet end of the cell. Alpha radiation from the liquid is detected by a zinc sulphide screen 19 deposited on a light guide which couples the screen to a photomultiplier 39. The protective film 20 consists of a P.T.F.E. strip fed from a drum 21 to a take up drum 22 and when the area of P.T.F.E. across the face of the screen 19 has become contaminated a motor (not shown) is used to drive the drum 22 and bring a new area of P.T.F.E. across the screen 19. For calibration a standard alpha source on a plate (not shown) is remotely controlled to move between the liquid 7 and the screen 19. Condensation on the P.T.F.E. strip, the screen 19 or the standard source from the air is prevented by heating the incoming air by an electrical heater 26.
