Title: Improvements in or relating to the manufacture of titanium
Inventor: QUIN JAMES PATERSON
IPC: C22B34/12
Filed: 1951-09-03
Abstract: A titanium halide or a mixture of titanium halides is reacted with an oxide-free sodium amalgam at a temperature below the boiling point of mercury, and metallic titanium is isolated from the reaction product. Titanium tetrachloride and sodium amalgam may be brought into contact, in the presence of an inert gas such as argon, at 300 DEG C., the amalgam having been first filtered through glass wool.  After reaction, the products are filtered, preferably through a filter bed of powdered titanium.  The sludge is then heated to drive off unreacted mercury and sodium, and the titanium metal sintered above the melting point of sodium chloride and below 1200 DEG  C., e.g. at 950 DEG  C., in the presence of the sodium chloride formed in the reaction.  The titanium is then recovered by removing the salt by bleaching or by vacuum distillation. Titanium di- and tri-chlorides may also be used.  The amalgam may contain 0.05-4 per cent of sodium.

Abstract: 948,047. Cutting webs. BELOIT EASTERN CORPORATION. May 30, 1962 [June 2, 1961], No. 20896/62. Heading B4B. A web-severing system comprises a support over which the web is arranged to move longitudinally, and first and second shearing members 11, 13 supported respectively on first and second carrier members 24, 27 which are disposed on opposite sides of the web and supported by first and second guide members 25, 28 for movement transversely with respect to the web, the transverse positions of both of the carrier members along the guide members being remotely controllable by a power-actuated unit. The shearing members consist of a blade 11 which is rotatably mounted on a bracket 110 depending from the carrier member 24 and a band 13 which is rotatably mounted on the carrier member 27 and driven by a motor 106, frictional engagement between the blade and band rotating the blade. The carrier member 24 is movable along the guide member 25 by a rack-and-pinion mechanism 29, 30 driven from a unit 33 and a motor 35, and the carrier member 27 is similarly movable along the guide member 28 by a rack-and-pinion mechanism 31, 32 driven from a unit 34 and a motor 36, the units 33, 34 each consisting of a pair of selectively-operable forward and reverse clutches and reduction gearing connecting the motors to the pinions and control transformers also connected to the pinions. The transformers in the units 33, 34 are connected by lines 40, 41 to respective selsyn generators in control units 42, 43 which contain amplifiers connecting the control transformers to the forward and reverse clutches of the units 33, 34. If the rotor of the selsyn generator of the control unit 42 is rotated by a knob 45, a voltage is induced in its stator and applied to the stator and rotor of the control transformer in the unit 33. The voltage in the rotor of the transformer, is fed to the amplifier, which includes a phase-sensitive circuit and the output of which is fed to one or other of the forward and reverse clutches of the unit 33 to enable the motor 35 to move the carrier member to a position corresponding to the movement of the knob 45. Similar control of the lower carrier member may be effected by rotation of a knob 46 on the unit 43. In addition, a three position switch 48 can be moved to a second position in which the movement of the lower carrier is controlled by the unit 42 and to a third position in which the lower carrier is controlled by a selsyn generator 37 on the upper carrier 24 whereby the lower carrier follows the movements of the upper carrier. When the carriers are in position, a switch 47 is operated which stops both motors 35, 36 and engages both the forward and reverse clutches of each unit 33, 34 to lock the carriers against movement. A plurality of pairs of slitter units may be used and a pair of switches 92, 93, 94, 95 are provided on the carriers of each unit to automatically disconnect the drive to a unit if it abuts another or an end stop during adjustment.

Title: Method and apparatus for texturing thermoplastic yarn
IPC: D02G1/14
Filed: 1965-05-18
Abstract: In a continuous texturing or crimping process, thermoplastic multifilament yarn(s) is drawn between stretching rollers (which may be heated) and is then introduced, within a jet nozzle, into a stream of hot gas e.g. air or superheated steam, whereby the yarn is directed and hurled towards the nip of converging indented conveying surfaces formed on driven rollers or by chain belts carried thereby. The heated yarn impinges against, and is entrained by cavities on at least one of, the surfaces, passes through a clearance space between the rollers or parallel runs of the belts (which may be cooled by water sprays) and the crimped p  yarn is withdrawn and cooled or further cooled (to set the crimp) by a compressed air aspirator and forwarded to "draw-out" rollers.  The yarn travels through the nozzle, Fig. 4 (not shown) within a hypodermic needle from which it emerges in a nozzle extension wherein it is met by the gas stream which has been directed from a supply pipe through an extended chamber of annular cross-section concentric with the needle.

Abstract: 686,423. Perforating plastic sheet material; imitation woven material. UNION CARBIDE & CARBON CORPORATION. Aug. 23, 1950. [Sept. 8, 1949] No. 20913/50. Classes 31 (ii) and 140. [Also in Groups V, IX and XVI] Thermoplastic resinous sheet which is not thicker than 0.020 inch is perforated by heating it to softening temperature and pressing it between an open-mesh woven wire screen (or a hard surface bearing a pattern corresponding to the screen) and a smooth backing surface. The screen or pattern is so fine that the perforated sheet is substantially impervious to water. For sheet up to 0.012 inch thick the screen has 60 to 20 meshes per inch of wire, and the wire is 0.006 to 0.015 inch in diameter. For sheet from 0.012 to 0.020 inch thick the screen has 25 to 10 meshes per inch of wire, and the wire is 0.010 to 0.030 inch in diameter. At the points of cross-over of the wires of the screen there is an extra thickness which pierces the sheet, and simultaneously with perforation the screen pattern is embossed on the sheet, giving it a woven appearance. Fig. 1 shows a thermoplastic sheet 11 into which is pressed a screen 12 by means of heated plates 10. In Fig. 2 the sheet 11 is pressed between a plate 10 and a screenengraved plate 13. In a further modification, Fig. 3 (not shown), the sheet may be preheated and fed between a screen-engraved roll and a smooth roll, these rolls being preferably cooled. The screen may be single-crimped or doublecrimped, Figs. 4 and 5 (not shown). The sheet material may be made from vinyl chloride-vinyl acetate copolymer. The perforated product of the invention may be used for making raincoats or automobile seat covers. The Specification states that thermoplastic sheet has previously been perforated by discharging an electric arc therethrough. Specification 627,546 is referred to.
