Title: The manufacture of wool-like artificial fibres
IPC: D01F2/06
Filed: 1934-01-10
Abstract: Wool-like artificial fibres are manufactured by treating newly spun and not yet dried artificial fibres of regenerated cellulose, which has a high affinity for substantive dyestuffs, i.e. which is capable of absorbing when dyed with Diamine Pure Blue FF at 20 DEG  C. at least half of the maximum quantity of dyestuff which it is capable of absorbing when dyed at higher temperatures, and which has been freed from metallic compounds, acids or sulphur, and if desired, bleached and washed, with organic liquids capable of dissolving water until the fibres only contain the molecular water usually present in the commercial material.  In an example, newly spun copper silk freed from copper and acids is introduced immediately after being centrifuged or pressed into a sufficient amount of alcohol (95 per cent).  It is then advantageously centrifuged and separated from the remaining alcohol by an after-treatment with, for example, carbon tetrachloride or ether. The last used solvent is recovered by evaporation.  Other liquids customary for removing water and containing, if desired, some water themselves, may be used singly or several in admixture or in succession.

Title: Complex hydride compounds
IPC: C07F5/06
Filed: 1958-01-10
Abstract: In the production of high complex hydrides of formula MEH4.nE1H3, where M is Li, Na, K, 1/2 Be, 1/2 Mg, or 1/2 Ca, E and E1 are th same, or different, trivalent element and n is 1/2 or 1-16 (see Group III), in, as solvent, an ether, thioether, or amine, e.g. tetrahydrofuran, diethylether, or thio-ether, or isopropylamine, the hydride products may be isolated as complexes with the solvent by crystallizing or freezing out.  Thermal decomposition of the solvates may give a lower solvate with fewer additive hydride molecules.  A solvate of a low molecular polarity solvent may be converted to the solvate of a higher molecular polarity solvent by extracting the solvate with the higher polarity solvent.  The Specification lists and exemplifies a number of solvates including tetrahydrofuranates of complexes of Li, AlH4 and BH3, or AlH3, LiGaH4 and BH3, CaAlH4 and BH3, and NaAlH4 and BH3 with, or without, AlH3, diethyl etherates of complexes of LiGaH4 and GaH3, or AlH3, and diethyl thio-etherates of a complex of CaAlH4 and BH3.ALSO:High complex hydrides of formula MEH4.nE1H3 where M is Li, Na, K, 1/2 Be, 1/2 Mg, or 1/2 Ca, E and E1 are the same, or different, trivalent elements, and n is 1/2 or 1-16, are prepared by introducing the hydrides involved into a solvent and reacting with exclusion of air and moisture.  The reaction may be effected between simple hydrides (MH, EH3, and E1H3), simple and double hydrides (e.g. E1H3 and MEH4), or double hydrides (e.g. MEH4 and E(E1H4)3), and the hydrides may be produced in situ, e.g. by reaction of simple, or double, hydrides with halides, e.g. BF3 or AlCl3 or with B(OR)3 or by reaction of metal, e.g. Ca and Al, with H2 or C2H4.  The reaction products may be isolated from the solvent ether, thioether, or amine (including NH3), e.g. tetrahydrofuran, diethyl ether, or thioether, or isopropylamine, by crystallizing definite solvates, or freezing out the oily substance.  Thermal decomposition of the solvates gives the hydride, or a lower solvate with fewer additive hydride molecules.  A solvate of a low molecular polarity solvent may be converted to the solvate of a higher molecular polarity solvent by extracting the solvate with the higher polarity solvent.  The Specification lists a large number of compounds and solvates, and exemplifies the preparation of some, including aluminium hydrides, gallium hydrides, and indium hydrides of Li, Na, Ca and Mg complexes with various proportions of borine (BH3) and hydrides of gallium, indium and aluminium.  In some cases more than one E1H3 compound is present in the complex.  A number of tetrahydrofuranates and diethyl-, and di-ethyl thio-, etherates are listed.

Title: Improvements in and relating to methods of manufacturing semi-conductor devices
Inventor: JOCHEMS PIETER J W
IPC: H01L21/00
Filed: 1959-01-14
Abstract: 906,941. Semi-conductor devices. PHILIPS ELECTRICAL INDUSTRIES Ltd. Jan. 14, 1959 [Jan. 17, 1958], No. 1390/59. Class 37. In the production of a semi-conductor device, the removal of some part, such as selected regions of a layer required to act as a mask in a later operation, is effected by projecting an abrasive or other medium against the surface in the region of a projecting electrode whereby removal is effected except in the region of the electrode shadow. Fig. 2 shows a P-type germanium body with an N- type layer 2, an alloyed rectifying contact 3 and an ohinic contact 4, both to the N-type layer 2. The body and electrodes are covered with a lacquer such as a solution of nitro-cellulose in butyl acetate. A mixture of air and butyl acetate is then sprayed on to the device in the directions of arrows 8 and 9 (Fig. 4) so that all the lacquer layer is removed except that portion lying on and between the electrodes. The device is then dipped into an etching solution of hydrofluoric and nitric acids to dissolve away the N-type layer 2 except for the region between electrodes 3 and 4. Removal of the lacquer layer provides a transistor as shown in Fig. 6 comprising base electrode 4 and emitter 3, the main P-type semi-conductor zone 1 forming the collector. The projected medium for removing the material may consist of an electron beam or a light beam in conjunction with an etching process. Leads may be added to the electrodes and the body soldered to a nickel strip before the process commences, and the invention may be applied to circular and annular shaped electrodes.
