Title: Improvements in and relating to electrical switching devices for measuring or control apparatus
IPC: H01H29/20
Filed: 1934-04-19
Abstract: 437,110. Actuation of switches. JOENS & CO., GES., W. H., 33, Franklinstrasse, D³sseldorf, Germany. April 19, 1934, Nos. 11839 and 11840. Convention dates, May 12, 1933 and Jan. 16, 1934. [Class 38 (v)] [See also Group XXXVIII] In a control device, e.g. for maintaining temperature constant, wherein a pointer f of a measuring or like instrument moves over a scale, and wherein a switch is operated when the pointer reaches a particular position, the switch consists of a mercury tube a mounted on a double beam b forming part of a parallelogram and carrying an actuating plate c which lies between two continuously-reciprocated members d, e, the arrangement being such that when the pointer f lies clear of the plate c the switch occupies one position and when it lies so as to be gripped between the plate c and the member d it assumes another position. Fig. 1 shows the first position. The U-shaped members d, e are pivoted as shown and actuated by two continuously rotated cam discs g, h so as alternately to grip the plate c and move apart from it. The member e is omitted from the one part of the Figure for the sake of clearness. When the pointer f moves to the right, it comes between the members c and d, so that when the member d moves upwards again the pointer is pressed by it against the member c and the member c is thereby raised so as to tilt the switch into its other position. When the pointer f moves back again, the member e at its next reciprocation will move the switch back. In a modification, Fig. 4, the switch has three positions, a central position in which the circuit to a motor is broken and two end positions in which the motor is caused to run in forward or reverse direction. These three positions are determined by the pointer f being free of the member c, engaging a projection i on the member c or engaging the main portion of the member e.

Abstract: 1471240 Preparing tertiary phosphine oxides HOECHST AG 21 March 1975 [1 April 1974] 11929/75 Heading C2P A tertiary phosphine oxide (R 1 )(R 2 )P(O)CH 3  wherein R 1  and R 2  are alkyl, alkenyl or alkynyl or an optionally substituted cycloalkyl, aralkyl or aryl radical having up to 18 carbon atoms is obtained by splitting off formaldehyde and hydrogen halide at a temperature within the range 150‹ and 350‹ C. in the presence of added hydrogen halide gas from a molten compound of the general formula in which X is halogen, separating off the formaldehyde and hydrogen halide split off from the reaction mixture, during or after the reaction, and separating the tertiary phosphine oxide from the crude reaction product, e.g. by distillation or crystallization. The gaseous formaldehyde and hydrogen halide may be passed through a condenser to liquefy the formaldehyde and the hydrogen halide absorbed in water or aqueous NaOH solution or the condenser may be replaced by a scrubbing column charged with water. Hydrogen halide dissolved or absorbed in the reaction product may be recovered by stripping the melt with nitrogen, CO 2  or argon or by treating the melt with an alkali metal- or alkaline earth metal carbonate and filtering off the metal halide formed. Examples are given for the production of trimethylphosphine oxide and dicyclohexylmethyl phosphine oxide.
Patent GB-434547-A (GB)
Title: Manufacture of artificial silk, threads, sheets, ribbons or the like
IPC: D01F2/08
Filed: 1934-04-20
Abstract: In the manufacture of artificial silk, ribbons, sheets, and the like, freshly prepared bleached pulp obtained by digesting cellulosic materials with nitric acid, is converted without drying into alkali-cellulose, xanthated, and dissolved to form a viscose containing more than 5 per cent, preferably more than 6 or 7 per cent of cellulose.  Preferably, the viscosity of the cellulose is lowered by treating the alkali-cellulose with a gas containing oxygen, e.g. air, in the presence of an alkali sulphide or polysulphide.  For example, the pulp may be mercerized in the presence of alkali sulphide and then treated with air, or the alkali-cellulose may be treated with air containing hydrogen sulphide.  In an example, wood is disintegrated by means of nitric acid, extracted with waste liquor containing alkali sulphide, and bleached.  The bleached pulp, after treating with solutions containing caustic soda and sodium sulphide, is centrifuged, during which process the copper viscosity of the cellulose is reduced to about 45" due to the action of atmospheric oxygen. The alkali cellulose is xanthated and dissolved to produce a viscose containing 7,5 per cent of cellulose and 6,5 per cent of alkali.  The ripened viscose is spun into acid baths, giving an artificial silk having a tensile strength of 150--160 grams per denier.
