Title: Improvements in or relating to electrolytic cells for the production of metals
Inventor: RANSLEY CHARLES ERIC
IPC: C25C3/16
Filed: 1957-05-01
Abstract: Titanium carbide having a low oxygen content is made by mixing selected quantities of rutile and carbon (coke) and reacting the mixture at 2000 DEG  to 2500 DEG C. removing gaseous and volatile products out of contact with the mixture at a high temperature at which decomposition of CO cannot occur, and cooling the mixture rapidly.  In an example, stated quantities of rutile and coke were milled together and mixed with cane molasses, the mixture being extruded, dried at 100 DEG  to 110 DEG C. and fired at 1000 DEG C. After cooling, the material was heated for 1 minute at 2300 DEG C., gases &c. allowed to escape at 1500 DEG C., and the resulting TiC rapidly cooled.  After crushing, the TiC was hot- or cold-pressed (see Group II).  Reference has been directed by the Comptroller to Specifications 784,695 and 784,696.ALSO:Current-conducting elements (see Group XXXVI) are made of TiC, ZrC, TaC or NbC by a hot or a cold-pressing process.  In the hot-pressing process, TiC is subjected to a pressure of 0,5 to 5,0 tons p.s.i. while its temperature is raised to 1600 DEG C. to 2700 DEG C.  According to the Provisional Specification, in the cold-pressing process, a TiC or ZrC powder of mean diameter 1 to 2 microns is mixed with a binder such as paraffin wax prior to compacting at 3 tons p.s.i., or, alternatively, to extrusion.  The carbide is then prefired at 1100 DEG C. (1600 DEG C. for ZrC) and then fired at 1600 DEG C. (2200 DEG C. for ZrC).  The content of free carbon in the finished article may be reduced by incorporating calcined alumina, e.g. 2,5%, in the TiC prior to compaction.  Further, the articles may be impregnated with aluminium at 1100 DEG C. to 1150 DEG C. in vacuo.  The hot pressing and sintering is carried out in vacuum or in hydrogen.  Reference has been directed by the Comptroller to Specifications 784,695 and 784,696.

Abstract: 719,498. Moulding ceramic material. PHILIPS ELECTRICAL INDUSTRIES, Ltd. June 6, 1952 [June 9, 1951], No. 14318/52. Class 87(2) Ceramic articles are made by mixing the starting material with a liquid to form a mixture from which the whole or part of the liquid is then removed by a filter press the inner space of which constitutes a shaping die. Initially, the parts are in the position shown. After the mould 6 and sump 12 have been exhausted through suction pipe 13 valve 7 is opened to allow material to flow into the mould under pressure of the piston 4. Valve 7 is then closed, the suction is relieved and the piston 16 lowered until it is almost flush with the inner walls of the mould. The volume swept out by the piston 16 is equal to the volume of liquid expressed from the material through the filter cloth 8 and drainage holes 11. This liquid flows from the sump 12 to a storage vessel to be re-used in subsequent moulding operations. After the moulding operation the piston 16 and die-part 15 are raised enabling the article to be removed from the open die. Alternatively, vacuum may be created beneath the piston 16 and the article raised with the die-part 15. Admission of compressed air to the space 20 by means not shown enables the moulding to be released. The moulded material may be pure titanium dioxide, or a mixture containing the oxides of barium or magnesium. The liquid used may be water, alcohol, acetone or ether.

Filed: 1927-06-02
Abstract: 279,383. Alderfer, S. W. Oct. 20, 1926, [Convention date]. Extrusion machines. - Beads for pneumatic tyres are formed by drawing a number of separate wires through a heated die, forcing rubber in and around the wires during the passage through the die, cooling the band formed, compressing it and winding it to form a bead. The wires 4 are drawn from separate spools through a die 5, sets of wires passing over and below a grooved wedgeplate 35 held by arms 34 in a die to a throat 44, rubber being forced by a feed screw through a chamber 41 in the die so as to surround the wires and further rubber being consolidated about the issuing band by a conical die 45 through which the band passes to a cooling device 10. The band is drawn through the die by a pressure device comprising upper and lower pulley belts 54, 55, a lower fixed guide plate 60 and an upper weighted pressure plate 61, which maintains the band in flat position and at the same time compresses it. The formed band passes from the compressor over a compensating pulley 68 to a winder 15 where it is formed into a bead in layers covered by a fabric 16 and afterwards compressed to the usual triangular section shown in Fig. 14. The winder runs intermittently to allow of the bead being severed, and during the spell the compensator pulley takes up the slack.
