Title: Thermal shaping of corundum and spinel crystals
IPC: C30B29/26
Filed: 1947-02-26
Abstract: 621,662. Gems. LINDE AIR PRODUCTS CO. Feb. 26, 1947, No. 5538. Convention date, March 1, 1946. [Class 43] [Also in Group XI] A small rounded gem is made from a thin crystalline rod of corundum or spinel by rotating the rod about its longitudinal axis and simultaneously applying to a free end thereof a heating medium of high intensity, e.g. oxy-natural gas flame or oxy-hydrogen flame, until a bulb is formed, after which said bulb is thermally or mechanically severed from the rod and may then have a finishing operation applied to it, e.g. it may be cut or ground. The heating medium is such that the material is heated at least superficially to its melting point, surface tension causing the melted material to assume a generally spherical shape. One end of a crystalline corundum or spinel rod 11, Fig. 1 is preferably tapered, e.g. by grinding, after which the other end is mounted horizontally in a chuck 13 rotated e.g. by an electric motor 15. A burner 17 is held adjacent the free end of the rod so that a thin sheet-like flame 19 impinges normally against a longitudinal zone of the rod 11, said flame being formed by one or more rows of jets, which jets are larger at the ends of the rows than in the middle thereof, with the result that the ends of the zone are heated more rapidly and to a greater depth than the middle, so that a bulb 39, Fig. 10, connected by a thin neck 41 to the rest of the rod, is formed. The bulb 39 is then cut or broken off, or severed by a flame, from the rest of the rod at or near the neck 41 to provide a generally pear- or teardrop-shaped body. The remainder of the rod 11 now has a flame-formed cone on its free end and the bulb-forming process can be repeated. In another method, Figs. 14 and 15, a rod 45, with or without a tapered end, is mounted as before, and a flame 53, preferably multi-jet, is made to impinge normally against a circumferential end portion of the rod to form a bulb 55. After formation of the bulb the flame is moved so that it impinges against a zone of the rotating rod slightly spaced from the base 57 of the bulb, whereupon successive portions of the surface of the rod in this zone are melted and, under the influence of surface tension and the dynamic erosive action of the hot gases in the flame, are displaced longitudinally in both directions from said zone to form a neck 59. The portion of the rod which flows away from the bulb 55 forms a second smaller bulb 61 on the main body of the rod, while the portion which flows towards the bulb 55 is incorporated therewith to produce a pear- or teardrop-shaped body which is severed from the rod as before. The whole process can now be repeated on the bulb 61 left on the rod. A teardrop produced by these methods can be made into a cabochon or pendant, for example, by abrading material from it to form a plane surface extending either transversely or longitudinally thereof respectively.

Title: Improvements in or relating to the rolling of metal strip
IPC: B21B15/00
Filed: 1936-08-17
Abstract: 463,939. Rolling; winding. WILLIAMS, W. P. (American Rolling Mill Co.) Aug. 17, 1936, No. 5596/37. Divided application. [Class 83 (iv)] After rolling a metal strip 29. back and forth through a mill 47 by coilers 27 and 61 the strip is severed at the coil 61 to leave the trailing portion of the strip still threaded through the mill and held by the pinch rolls 31 so that the leading end of a succeeding unrolled coil 11 can be attached to the unrolled trailing end of the previous coil when repeated rolling back and forth can proceed as follows : Before rolling, the individual sheets are led from a coil 2 between straightening rolls 3, each end is sheared square at 5 and then welded end to end at 6. They then pass before a flash cutter 7 of pinchroll 8 and are coiled up at 11. This now-continuous strip is threaded round tensioning rollers 32 and the static tensioning roller 40 and through the mill 47 to the other static tensioner 52 and the end is fixed on the tight coiler 61. The strip is now rolled from left to right until its trailing end is just held by the pinch rolls 30, 31 when the mill is reversed and dropping of the deflector plate 28 directs the strip into a coiler 27 provided with an outside sheath of roller chain 18 tightened by a weight 26 to press the strip against the drum 27, which thereby frictionally grips it and coils it up. The strip is then rolled to-and-fro and finally wound upon the drum 27 or on the tight coiler 61 and severed when the coiler 61 is then swung round a pivot 58 through 180‹, so bringing another tight coiler 62 into position for rolling the next strip while the first rolled strip at the same time can be led away to a storage coiler 70 or a shears. The initial unrolled length of the first strip on coil 61 is waste. The trailing end held by the pinch rolls 30 is welded to a new supply strip which has meantime been accumulated on the reel 9 and so pulls and threads the new strip through for repeated rolling as before. The tight coilers 61 or 62 are driven through a clutch from a motor while the coiler frame is turned through 180‹ by a separate swing motor.

Title: Improvements in the Heating Walls of Coke Ovens and the like and in Blocks for the Construction of such Walls.
Inventor: ROBERTS ARTHUR
IPC: C10B29/02
Filed: 1919-03-07
Abstract: 135,091. Roberts, A. March 7, 1919. Coke ovens.-In a heating-wall formed of blocks, which are recessed to provide passages for the heating- gases within the body of the wall, the construction is such that more heat is transmitted to one face of the wall than to the other. The blocks are formed with end portions shaped to engage adjacent blocks as shown in Figs. 2 and 8, and the unequal transmission is effected by varying the depth of the recesses 21 along the reduced portion of the block, as shown in Fig. 2, or by corrugating the reduced portion at one end as shown in Fig. 8. In building a coke oven the blocks are assembled as shown in Fig. 11, so that more heat is transmitted from the wall 15 to the oven 13 than to the air-heating passages 17.
