Abstract: 1361282 Evaporators, falling-film type IMPERIAL CHEMICAL INDUSTRIES Ltd 28 Feb 1972 [3 March 1971] 5923/71 Heading BIB A falling-film evaporator comprises a cylindrical column 1 surrounded by a heating jacket 21, the liquid which is to be submitted to evaporation being maintanied as a film on the inner wall of the cylinder by means of resilient demountable blades 19 made of organic polymeric material, preferably polytetrafluoroethylene, which are freely mounted in slots in horizontal arms 18 attached to rotor rod 5, the arrangement being such that, when the rotor is in motion, the blades 19 exert light pressure on the inner wall of the column. The column 1 and the rod 5 may be made of glass. A liquid mixture is supplied to the evaporator from slide funnel container 11, flow control tube 15 being adjusted by screw joint 14 so that the gap between socket 13 and the taper cone at the lower end of tube 15 is regulated whereby a steady feed of the liquid mixture to column 1 is achieved. The more volatile constituents of the mixture flows as vapour to condenser 9; and the condensate is collected in receiver 10. The resdiual liquid flows to receiver 3. Inert gas, such as nitrogen, may be passed through the evaporator from inlet 26. Reduced pressure may be applied at the neck 25 of receiver 10. The jacket 21 may be supplied with the vapours of toluene, xylene, o-chlorotoluene, o-dichlorobenzene, acetophenone or chloronaphthalene by boiling the appropriate liquid in flask 22. The evaporator may be used for separating o-dichlorobenzene from a solution of an organic polyisocyanate.

Title: Improvements in or relating to the manufacture of titanium
Inventor: DAVIES ERNEST
IPC: C22B34/12
Filed: 1956-02-27
Abstract: In a process for the manufacture of titanium by the reaction of titanium tetrachloride with metallic sodium, pure titanium is separated from the product mixture in a single filter vessel, the ground product mixture being fed to the vessel together with dilute acid, so that a concentration of between 15 and 25 per cent by weight of sodium chloride is maintained in solution, while the solution is filtered continuously, preferably until the concentration of leached titanium builds up to a slurry containing 300 kg. of titanium per cubic metre.  A continuous flow of acid is maintained through the filter vessel, which may be fitted with a stirrer.  Preferably the filter comprises polythene cloth mounted between two perforated metal plates.  The impurities are dissolved from the mass, and fine particles of titanium (less than 100 B.S.S.) having a high hydrogen content, pass through the filter.  The remaining pure titanium is then washed with weaker acid and finally with water, yielding titanium which after arc melting contains 0.002 per cent of hydrogen and has a hardness of 130 D.P.N.

Title: Improvements in supports or mountings for telephone receivers
IPC: H04M1/04
Filed: 1919-03-14
Abstract: 144,781. Jones, E. T. March 14, 1919. Mounting and supporting.-A support for a telephone receiver comprises a lazy-tongs which depresses the switch hook when closed. One limb of the lazy-tongs is pivoted at c to a tube d which is clamped so as to turn with the transmitter k about the bolt h and can also turn slightly about its own axis. The limb b<3> of the tongs passes through a slot p in the tube d and a corresponding slot in a plunger r within the tube, and it carries a pin q which moves in a slot t in this plunger. When the lazy-tongs is closed the pin q reaches the bottom of the slot t and depresses the plunger together with the arm u, which actuates the switch-hook. The arm u is so shaped that it does not affect the switch-hook when rotated about the axis h. It is adjustably screwed into the plunger r, so that it is possible to regulate the conditions of lift of the plunger, which is held down by friction until the pin q engages the top of the slot t. The receiver may be of the watch, bell, loud-speaking or megaphone type, and may be rigidly attached to the arm or held in a clamp or clip. A second receiver may be supported on a fixed clip fastened round the neck of the stand.

Abstract: 1,080,632. Semi-conductor devices. WESTINGHOUSE ELECTRIC CORPORATION. Feb. 15, 1966 [March 1, 1965], No. 6524/66. Heading H1K. A multi-region semiconductor device comprises a mounting member (52, Fig. 4, not shown) of good thermally and electrically conductive material having a flat surface (56) supporting a transistor (10). The transistor, shown in Fig. 1, is formed from a semi-conductor wafer 12 of one conductivity type and has a collector region 14 of opposite conductivity type defining a P-N junction extending substantially parallel to the major wafer surfaces over the entire wafer area, a base region 15 comprising concentric sections 16, 18, 20 of the wafer, and an emitter region 21 comprising concentric rings 22, 24 of the opposite conductivity type. A pair of semicircular electrodes 30, 32, Fig. 2, having projections 34-44 of corresponding shape to the base and emitter regions, are placed in contact with the wafer surface and are loaded by means of a spring (84) which is held by a snap ring (88) in a tubular inner housing (64) fixed to the mounting member (52).

Title: Improvements in or relating to apparatus for use for example for vulcanizing purposes
IPC: B29D30/06
Filed: 1945-03-16
Abstract: 595,335. Vulcanising moulds for pneumatic tyres, tubes &c. STEVENS, A. H. (Firestone Tire & Rubber Co.). March 16, 1945, No. 6680. [Class 87 (ii)] The apparatus comprises at least three movable sections and includes a rotatable annular locking ring mounted on and engaged about one of the sections and being adapted to selectively lock the sections together, the ring having three operative positions, and a pressureoperated device connected to the ring and adapted to oscillate it to move it selectively from one of the operative positions to another. In the dual-mould vulcaniser shown there are three mould sections, the lower, 20, fixed to the stationary vulcaniser part 12, the upper, 22, fixed to the movable vulcaniser part 13, and the intermediate, 21, keyed to the locking ring 18 by ears 37, 38. The mould sections are steam-jacketed, steam being applied by flexible pipes such as 24 and 25. The locking ring 18 has lugs 31, 35 engageable with lugs 30, 34, on the vulcaniser parts and is rotatable into three positions. In one position the lugs 34 and 35 only are interengaged and when the cover 13 is raised by means of the arms 17 the ring 18 and intermediate mould part 21 also are raised, thus opening the lower mould. In another position the lugs 30, 31 only are interengaged and when the cover is raised the ring 18 and mould part 21 remain down, thus opening the upper mould. In the third position both sets of lugs 30, 31 and 34, 35 are interengaged and the vulcaniser is locked. The means for rotating the locking ring consists of two double-acting hydraulic cylinders 42, 43, secured together by a common head 44 and slidable bodily on rods 41 fixed to the framework. Also slidable on the rods 41 is a crosshead 56 having a pin 60 engaged with a slot in a bracket 62 fixed to the locking ring. The crosshead is fixed to one piston rod 55, the other piston rod 50 being fixed to the framework. Thus, by extending the piston rod 50 the ring 18 is moved to the right from the central position shown in Fig. 3, or by retracting the rod 55 it is moved to the left. The hydraulic valves, not shown, are operated by a manually-controlled pilot valve. When the cover 13 is raised the pin 60 disengages from the bracket 62, re-engaging when the cover is lowered.
