Title: Improvements in or relating to processes for purifying substances by drawing a molten zone therethrough
IPC: C30B13/00
Filed: 1955-05-10
Abstract: In a zone refining process small quantities of one or more additives which promote the removal of one or more impurities during the zone-drawing process are added to the molten zone of the substance to be refined.  The additive may be a metal having an atomic weight greater than 50; it may form with the impurity a compound which is only dissociated to a small extent at the melting point of the substance; it may have a higher affinity for the impurity than for the substance; it may have low coefficients if distribution and diffusion in the substance; and the end of the substance may be removed after the passage of one or more molten zones therethrough. The Specification contains an example of the use of ultra-pure iron for the removal of silicon from a germanium rod.  For semi-conductors the additive may act as a donor, an acceptor, a trap, or a recombination centre, and after the completion of the process it need not be completely removed but serve to influence the electrical properties of the refined substance.

Patent GB-664956-A (GB)
Title: Improvements in the manufacture of acetals
Filed: 1949-05-23
Abstract: An acetal is produced by subjecting an alcohol and a keto compound to reaction in presence of an acid catalyst and a water-immiscible liquid forming an azeotrope with water having a boiling point below that of the reaction products and the alcohol used and continuously removing water formed in the reaction as an azeotrope with said liquid.  The preferred method comprises heating an alcohol together with an acid catalyst and the water-immiscible liquid feeding a keto compound into the hot mixture and continuously heating to effect the reaction and to distil off water produced as an azeotrope with said liquid. Specified water-immiscible liquids are benzene, cyclohexane, pentane, hexane and toluene and the catalyst may be sulphuric, hydrochloric, phosphoric, or toluene sulphonic acid.  In an example cyclohexane is added to a mixture of normal propyl alcohol and diluted sulphuric acid and the mixture is then heated almost to refluxing temperature in a still base, formalin being then added slowly as the mixture is refluxed.  The water is distilled off continuously as an azeotrope with cyclohexane and the mixture is condensed and the water layer separated, the cyclohexane being returned to the reaction zone.  When no more water separates from the distillate the catalyst is neutralized and unused formalin resinified by adding an excess of aqueous sodium hydroxide and the mixture again refluxed to remove the added water as an azeotrope with cyclohexane. After filtration to separate sodium sulphate the filtrate is fractionated (after adding calcium carbonate to give slightly alkaline conditions) to remove unreacted alcohol and the cyclohexane and the di-n-propyl formal is finally distilled at reduced pressure.

Abstract: 772,609. Braiding machines. ENSOR, A. J. May 11, 1955 [May 11, 1954; Nov. 5, 1954], Nos. 13778/54 and 32045/54. Class 74 (1). Wires 33 on their way to the braiding point, there to be braided about a core 15, pass over and under the radiused edges of a bush 21 and a member 29, whereby they are deflected and tensioned, the radiused edge of the member 29 lying closer to the core than that of the bush and means being provided to vary the axial distance apart of bush and member, thereby to vary the tension. The bush 21 and/or the member 29 may be loaded axially by a spring such as 21A and the outer diameter of the member 29 is less than that of the conical mouth of the bush so that the member can pass thereinto. An inward projection 23 on the bush centralizes the core. The member 29 may be undivided or may be divided into fingers 30 by saw cuts, the fingers being pressed inwardly to an extent determined by adjustment of a nut 32. The bush 21 and member 29 are readily detachable for substitution by others of different diameter and are movable towards and away from each other by means of lead screws 19, 27. In addition, either or both may be reciprocated axially, during braiding, to relieve tension intermittently and avoid tendency for the braid to form otherwise than on the core. Thus, the member 29 may be reciprocated by an electric motor 100 acting through an eccentric 101 and the linkwork shown.
