Abstract: 195,098. Farbwerke vorm. Meister, Lucius, & Br³ning. March 20, 1922, [Convention date]. Purifiers; purifier waste, revivefying,-In the purification of gaseous mixtures by the absorption of one or more of the components in active charcoal, a thin layer of charcoal is employed which is moved transversely through the stream of gas or over which the stream is passed in a transverse direction. The charcoal may be arranged, as in Fig. 3, as an endless layer 8 passing through the gas stream 8, the absorbed components being removed in an suitable manner between the points where the layer. leaves and re-enters the stream. Several such layers may be arranged .either concentrically or in succession for the recovery of the several components of the mixture. Alternatively an arrangement comprising gas delivery and collecting pipes 12, 11, Fig. 4, and vapour delivery and collecting pipes 13, 10, for the recovery of the absorbed components may be made to travel round the stationary charcoal layer 14. By regulating the rate of movement of the charcoal relative to the gas stream the composition of the absorbed fraction of the mixture can be varied so that it comprises either the most readilv absorbed constituent alone, or other less readily absorbed constituents in addition, and in the latter case the absorbed components may be separately recovered. Thus, the components absorbed from the gas stream 19, 24, 20, Fig. 6, by the travelling charcoal layer 21 are recovered by vapour supplied through inlets 31, 30, 29. The components are expelled in the inverse order of their absorption, and are separately collected in the chambers 28, 27, 26.

Title: Production of single crystal compounds
IPC: H01L29/00
Filed: 1962-03-02
Abstract: Pure single crystal forms of compounds of an element or elements from Group IIIb (Mendel<\>aeef), excluding boron, with an element or elements from Group Vb, e.g. gallium arsenide and phosphide, are prepared by heating the compound with hydrogen halide vapour to a temperature sufficient to cause reaction, e.g. 135-1200 DEG  C., and thereafter subjecting the resulting vaporous product to a lower temperature, e.g. 130-1195 DEG  C. to condense the compound in a single crystal form. The process may be carried out either in a closed system containing the compound and hydrogen halide vapour one part of which is heated to the reaction temperature and another part maintained at a lower temperature to condense the product, or by a continuous flow method wherein the hydrogen halide vapour is passed at 2-100 c.c./min. over the compound maintained at the reaction temperature and the resulting vapour passed to a condensing zone. Pressures of 0.01-10 atmosphere are specified. The process may be used to deposit epitaxial layers of the above compounds on substrates selected from the same group of compounds and silicon and germanium. Smoother, more uniform epitaxial films are obtained when they are deposited on (100) crystal faces or (111) crystal faces where the Group V atoms are exposed.  Other compounds specified are indium arsenide and phosphide and ternary compounds of the type GaAsxP1-x, GaPxN1-x, InAsxP1-x, and AlPxAs1-x, where x is greater than zero and less than one.

[Class 83 (iii)] Drills for wood and like relatively soft materials, comprise a shank carrying a tubular portion with a sharp cutting edge at its end, and a radial cutting edge on a member detachable from the tubular portion and located within it. The shank 11, Fig. 1, has an enlarged end terminating in a tubular member having an annular cutting edge 14 and provided with an opening 13 for the escape of cuttings and to afford access to a screw 19 that secures in place both an insert 15 having a longitudinal groove 16, and a cutter 18 having a radial edge 17 and projecting into a slit 20 in the tubular member. The parts are separated to permit easy regrinding. In a modification the shank is integral with the inserts, the tubular member being attached thereto. The radial cutting edge may be constituted by one edge of the insert and in this case is continued by a tooth formed laterally in the annular edge. The bore of the tubular member may taper outwards, the insert being correspondingly tapered ; this results in a thin annular edge and a tooth in it is then unnecessary. In a further modification the radial cutter is attached directly to the shank, the insert being dispensed with.
