Abstract: 486,065. Current meters ; wireless receivers. SIEMENS & HALSKE AKT.- GES. June 23, 1937, No. 17506. Convention date, June 26, 1936. [Class 37] [Also in Groups XXXV and XL] Rectifying apparatus for measuring highfrequency currents particularly in the short wave ranges comprises a coreless transformer a rectifier and a capacitance in a common casing, the apparatus being tuned to a fixed relationship between input alternating-current and output continuous-current. A transformer 4, 5 is mounted between flanges 2, 3 on support 1, one end of either winding being led out axially so that the transformer ratio can be adjusted by locating a winding end in holes or notches in one of the flanges. The condenser 7 is wound on the base 1, the conducting layers projecting at each side beyond the dielectric material and being wound with the connection wires 8. The rectifier 6 of very small contact surface is contained in a glass cartridge and is located within the condenser 7 being thus shielded electrostatically. The lead wire from the rectifier is preferably formed directly into the transformer secondary. The units are housed in an insulating tube 10 and the spaces filled with a sealing compound. The apparatus is about 40 mm. in length and 10 mm. in diameter and can be used with waves of the order of one decimetre.

Title: The preparation of new amino derivatives of dioxacyclopentane and of quaternary salts derived therefrom
IPC: C07D317/28
Filed: 1945-07-11
Abstract: Tertiary amino derivatives of dioxacyclopentane, of the general formula <FORM:0595963/IV/1> (wherein R represents hydrogen or an alkyl group, which may be substituted by a hydroxy or a dialkylamino group, R1 represents hydrogen or an alkyl group, and R2 and R3 represent identical alkyl groups) are manufactured by the action of a dialkylamine on the corresponding halogenated dioxacyclopentanes, which may themselves be prepared by heating a halogenated acetal of the type <FORM:0595963/IV/2> with a polyhydric alcohol of the type R4-CHOH-CH2OH (wherein R4 represents hydrogen or an alkyl group, which may be substituted by a hydroxy group or a halogen atom, permitting of subsequent substitution by a dialkylamino group). Quaternary ammonium salts, having physiological properties similar to those of acetylcholine, may be made by treating the tertiary amines with an alkyl halide or sulphate.  In examples: (1) ethylene glycol is heated with bromacetal and the resulting 2 - bromomethyl - 1 : 3 - dioxacyclopentane is heated with a solution of dimethylamine in benzene in a sealed tube to produce 2 - dimethylaminomethyl - 1 : 3 - dioxacyclopentane, which may be treated with methyl iodide to form the methiodide; (2) glycerol is heated with bromacetal and the resulting 2-bromomethyl - 4 - hydroxymethyl - 1 : 3 - dioxacyclopentane, which is slightly contaminated with 2 - bromomethyl - 5 - hydroxy - 1 : 3 - dioxacyclohexane, is heated with dimethylamine solution in a sealed tube, yielding 2-dimethylaminomethyl-4-hydroxymethyl-1 : 3-dioxacyclopentane and some 2 - dimethylaminomethyl - 5 - hydroxy - 1 : 3 - dioxacyclohexane, from which the corresponding methiodides may be obtained by the action of methyl iodide; (3) glycerine a -monochlorhydrin is treated as in (1) to give 2-bromomethyl-4-chloromethyl-1 : 3-dioxacyclopentane and from it (using 6 molecular proportions of dimethylamine) 2 : 4 - di - (dimethyl - aminomethyl) - 1 : 3 - dioxacyclopentane and its dimethiodide; (4) pentane - triol - 1 : 2 : 5 similarly yields 2-bromomethyl- and 2-dimethylaminomethyl - 4 - (31 - hydroxypropyl) - 1 : 3 - dioxacyclopentane and the methiodide of the latter.  The Specification as open to inspection under Sect. 91 comprises also manufacture of tertiary amines of the general formula given above in which R2 and R3 may represent two different alkyl groups and in which the dialkylamino group may be linked to the ring by a polymethylene chain instead of a single methylene group, and also a method of making the quaternary ammonium salts directly by treating the halogenated dioxacyclopentanes with a trialkylamine.  Reference is also made to the treatment of the product of example (2) above with acetyl chloride to form the acetyl derivative.  This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to weighing devices for indicating the weight of the pickling brine to be supplied to meat for the purpose of picking the latter
IPC: G01G23/20
Filed: 1933-06-26
Abstract: 402,360. Weighing-apparatus. BEISSER, C., 68, Ahrensburgerstrasse, Rahlstedt, Hamburg, Germany. June 26, 1933, No. 18211. [Class 143.] A weighing device for enabling the weight of pickling brine required for pickling meat to be determined without calculation is provided with a dial on which graduation marks (which may be replaced by an automatically-adjusted marking pointer) are arranged in relation to the positions of the weight indicator for the fresh meat at distances corresponding to the weights of pickling brine required for preserving the quantity of meat indicated by the weight indicator. In the form shown in Fig. 1, the dial is marked with areas f, g, rendered distinctive for example by alternate black and white colourings, by raised or sunk impressions, or by illumination. Within the distinctive areas are inscribed a series of graduations spaced in the present instance to facilitate the weighing out of brine equal to 7 per cent of the weight of meat to be treated. In using the device the meat is placed on the machine and the pointer registers on the dial in the usual manner. Assuming the pointer to have taken up the position shown viz., opposite a black area and at the fourth graduation therein, the operator adds brine to the meat until the pointer moves to the fourth graduation in the next area i.e., to the position a .. b, the admitted brine then amounting to 7 per cent of the weight of meat. If the operator wishes to admit 8 per cent of brine he allows the pointer to travel an extra graduation before cutting off the brine. In a modification, Fig. 2, the usual indicating pointer 2 is connected by gearing to a marking pointer 10 which is thus driven in advance of the pointer 2 by a steadily increasing amount so as to indicate a 7 per cent excess in weight beyond the indication of the pointer 2. Thus, after weighing the meat, the operator disconnects the pointer 10 and adds brine until the pointer 2 coincides with the pointer 10. Instead of employing the gearing shown, a cam and lever transmission may be used to actuate the pointer 10.
