Abstract: 819,604. Supply systems for discharge vessels. DORTMUND - HORDER HUTTENUNION A.G. March 15, 1957 [March 17, 1956], No. 8648/57. Class 38 (4). [Also in Group XL (a)] A glow discharge vessel 10 for treating workpieces is supplied from a D.C. supply 47, 54 across which is connected a resistor 61 and a capacitor 62, the discharge vessel being connected across the capacitor in series with an inductor 64. When the glow discharge breaks into an arc, the additional current through resistor 61 causes the voltage across vessel 10 to fall, and this is further reduced by the oscillatory swing of components 62, 64 to a value low enough to extinguish the arc. An additional resistor 65 which may consist entirely of the cable resistance may be connected in series with the inductor 64. A further resistor 68 supplies an auxiliary electrode 32 reducing the striking voltage. The value of resistor 61 may be reduced if an additional inductor 60 is connected in series. Suitable values for the components are given in the Specification.

Abstract: The invention comprises carbocyanine dyes of the formula: <FORM:0781210/IV (b)/1> where R and R1 are alkyl or substituted alkyl, R2 is aryl and X is an anion such as chloride, bromide, iodide, methylsulphate, ethylsulphate or p-toluenesulphonate.  These are made by treating ketones of the formula: <FORM:0781210/IV (b)/2> with a phosphorus oxyhalide and condensing the ketone halide with a benzthiazolium salt of the formula: <FORM:0781210/IV (b)/3> preferably in the presence of a base such as triethylamine.  R and R1 are preferably primary alkyl of 1-4 carbon atoms but may also be b -hydroxyethyl or benzyl; R2 is preferably phenyl, which may be substituted, e.g. by methyl or chlorine.  An example is given of the preparation of the dye in which R and R1 are methyl, R2 is phenyl and X is toluene-p-sulphonate.  Other dyes are mentioned in which R is ethyl, R1 is methyl or ethyl, R2 is phenyl and X is iodide.ALSO:Ketones of the formula <FORM:0781210/IV (a)/1> where R is alkyl or substituted alkyl and R2 is aryl, are obtained by condensing quaternary derivatives of 2-methyl-6-phenyl-benzthiazole with aroyl halides in the presence of an acidbinding agent such as pyridine, picoline or quinoline. Examples are given of the process where R is methyl or ethyl and R2 is phenyl.  R may also be propyl, butyl, benzyl or b -hydroxyethyl.  3 - Ethyl - 2 - methyl - 6 - phenyl - benzthiazolium p-toluenesulphonate is prepared as follows: p-xenylamine is condensed with sulphur monochloride to give 6-phenyl-benzthiazthionium chloride and the latter reduced to 2 - amino - 5 - phenyl - thiophenol (as zinc salt).  Ring-closure with acetyl chloride gives 2 - methyl - 6 - phenyl - benzthiazole which is quaternated with ethyl p-toluenesulphonate.

Abstract: 857,614. Temperature measurements. WESTINGHOUSE ELECTRIC CORPORATION. March 21, 1958 [March 28, 1957], No. 9105/58. Class 40 (1). [Also in Group XXXVI] The temperature of current - carrying electrical apparatus is measured by means of a magnetic member which becomes heated by the magnetic field due to the flow of current in the leads to the windings of the apparatus; the temperature of the magnetic member then gives an indication of the temperature of the apparatus. In Fig. 1, current is led to a transformer  winding 10 by leads 13, 14 around which is located a metallic member 19. Heat is generated in this by the magnetic field due to the current in the leads and also by conduction through the insulating liquid medium 11, and its temperature is measured by a thermocouple 24. The arrangement can be used to show the temperature of the winding since the magnetic member is fixed on account of the sloping leads 13, 14. The actual temperature of the member can be adjusted with thermal insulation, and by arranging gaps in the member to control its magnetic reluctance. The member can be supported outside the dielectric medium 11, and a thermistor or thermostat can be used to measure its temperature,
