Abstract: 353,462. Electromagnetic interrupters. SIEMENS & HALSKE AKT.- GES., Siemensstadt, Berlin. Feb. 21, 1930, No. 5846. Convention date, May 28, 1929. [Class 38 (v).] Where electromagnetic interrupters are employed as vibrating rectifiers for measuring purposes, the vibrating contact being joined mechanically to the relatively fixed contact through bodies having different temperature coefficients in order to prevent distortion of the contact-carrying member as by bending due to changes in temperature, the surfaces of the joint are symmetrically disposed, for example, by arranging duplicate surfaces at opposite sides of the relatively fixed contact-carrying member. As shown in Fig. 1 the magnetic reed 7 carrying the movable contact 18 is secured to the block 3 carrying the relatively fixed contact 4 by being clamped between a surface of the block 3 and an identical surface of a block 31 by a screw 5, thin mica insulating sheets being interposed between the surfaces of the joints. The reed is magnetized by a permanent magnet mounted below the base 1 and the energizing current is fed to coils 9 on a laminated magnet structure 10 formed with an air gap into which the free end of the reed projects. In a modified form of the contact support shown in Fig. 4 the member 22 carrying the relatively fixed contact 4 is clamped between a supporting block 19 formed integrally with the reed 7 and a corresponding metal block 20, the bearing surfaces and insulating sheets 8, 81 at opposite sides of the contact support 22 being made symmetrical to prevent distortion of this member and consequent alteration in the operation of the interrupter with changes of temperature.

Abstract: The invention comprises thermoplastic polyimino carbonates containing recurring units of the formula:  <FORM:0845650/IV(a)/1> and which may also contain recurring units of the formula:  <FORM:0845650/IV(a)/2> where R and R1 are the same or different, and are the residues of dihydric phenols which may contain substituents which neither react with cyanogen halides nor produce steric hindrance at the phenolic hydroxyl groups, e.g. halogen, nitro, alkyl or alkoxy groups.  The resins are prepared by reacting a cyanogen halide, e.g. bromide or chloride, with an alkaline solution of the dihydric phenol at temperatures up to 50 DEG C; phosgene may be added before, with, or, preferably, after the cyanogen halide.  Dihydric phenols mentioned are hydroquinone, resorcinol, bisphenol A, bis (4-hydroxy, 3-methyl phenyl)-2 : 2-propane, bis (4-hydroxy phenyl)-1 : 1-cyclohexane and bis- (4-hydroxyphenyl)-2 : 2-butane.  The alkaline solvents specified are trimethyl benzyl ammonium chloride, triethyl dodecyl ammonium chloride, N-methyl pyridinium chloride and/or aqueous Na OH in toluene, xylene, methylene chloride or CCl4.  The resins are soluble in benzene, chloroform, dimethyl formamide, acetone, cyclohexanone or ethyl acetate and may be used for surface coating.

Filed: 1957-02-22
Abstract: 825,091. Controlled non-linear inductors. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. Nov. 7, 1957 [Feb. 22, 1957], No. 6023/57. Class 40 (9). [Also in Group XXXV] D.C. voltage is stabilized by charging a capacitor from a rectifier through a " resetting " type of reactor, the " resetting " being controlled by variably discharging the capacitor back through the reactor (and a control valve) during the non-conducting half-cycles of the supply rectifier. The effect of discharge current due to rectifier leakage may be off-set by a control winding on the reactor carrying the current to an external load (not shown). The capacitor 5 is charged through the reactor 4 from a full-wave bridge rectifier 3, and the " resetting " current is determined by the triode 6 shunted across the input side of the reactor 4. The triode 6 is controlled by a fixed negative bias and a portion of the voltage across the capacitor 5.

Abstract: 277,389. White, G. N. March 8, 1926. Colouring plastic compositions. - Building materials such as cements, plaster, lime, asbestos, &c. are coloured by means of vat dyestuffs or colouring agents used in a state of dryness or suspension, e.g. in colloidal solution. The dyes may be applied either to the loose material or by way of painting or impregnation to the finished product. They may be converted into a finely divided state either by grinding or by oxidizing a solution of the leuco compound in presence of a dispersing agent. According to one example 5 lbs. of Caledon brilliant purple 2R standard paste is intensively ground in a Follows and Bate mill, optionally with addition of 6 pints of sodium silicate. The product is made up to 2¢ gallons with water and used as the gauging water for cement mortar containing 100 lb. of cement. In another example 5 lb. of standard paste is mixed with 2¢ gallons of 5 per cent caustic soda and reduced with sodium hvdrosulphite. 6 pints of sodium silicate and 3 pints of sodium carbonate solution are added. The mass is oxidized by blowing air through it, then made up to 2¢ gallons with or without a prior grinding operation, and used to gauge 100 lb. of cement.
