Abstract: 636,974. Sensitized photographic emulsions. KODAK, Ltd. Oct. 15, 1947, No. 27660. Convention date, Dec. 29, 1945. [Class 98 (ii)] The spectral sensitivity of a light-sensitive silver bromide, bromiodide, or chlorobromide emulsion and sensitized with a cyanine dye is modified by incorporating therein a pyridine base having at least one substituent on a carbon atom in the pyridine nucleus, and wherein all of the substituents present are selected from alkyl, alkoxy, hydroxyalkyl, aryl, aryloxy, alkylmercapto, arylmercapto, acyl and acyloxy groups and halogen atoms. The cyanine dye may be one which produces a second longer-wavelength sensitivity maximum at a higher concentration or on digestion of the emulsion at one concentration of the dye. 0.10 to 1.5 grams of pyridine base may be incorporated per litre of emulsion. Bases specified are 2-, 3-, and 4-methyl-, 2 : 3-, 2 : 4-, and 2 :6-dimethyl-, 2:3:4-trimethyl-, 2- ethyl-, 2-propyl-, 2- and 3-phenyl-, 2-benzyl-, 3-ethoxy-, 3-acetoxy-, 3-methylmercapto-, 2- chloro-, 3 :5-dichloro-, and 3 5-dibromopyridine.

Abstract: 610,054. Transmission line arrangements; automatic control of voltage; converting; inductances. GENERAL ELECTRIC CO., Ltd., and FRIEDLANDER, E. S. Oct. 22, 1945, No. 27741. [Classes 38 (ii) and 38 (iv)] An inductive reactor I having D.C. saturating windings II variably energized through a grid-controlled rectifier GR is connected across a long transmission line L to compensate for excessive capacitive power. Alternating current of adjustable phase angle for the control of the rectifier is derived from a network comprising a D.C. saturable reactor X in series with a condenser C and A.C. saturable reactor SR in parallel, as described in Specification 610,072, phase control being effected by manual or automatic control of the excitation of the D.C. winding CW of reactor X, this winding being fed from the line over a variable ratio transformer PT and a rectifier bridge MR. With switch SW thrown to the left the control is by manual adjustment of tapping T1. Automatic control by the voltage variations at transformer PT, accompanying changes of capacitive power, is obtained by throwing the switch to the right, when the rectifier MR is supplied through a network comprising in effect an A.C. saturable reactor SR1 in series with a capacitor C1, both being shunted by a further capacitor C2. Reactor SR may be in the form of a square wave transformer, as described in Specification 466,282. The reactor I may comprise two six-legged cores so wound as to avoid all odd harmonics up to the eleventh, the even harmonics being eliminated by symmetry of the D.C. windings II. Instead of six-legged cores, four-legged cores excited either in pairs or in triple groups, as shown in Figs. 3-5, may be used. In these Figures AW and DW denote the A.C. and D.C. windings, respectively, and R, R<SP>1</SP> denote fluxes 30 degrees out of phase due to inter-star connection. The reactor I may draw considerable magnetizing current without D.C. excitation, when it functions as a combined A.C. and D.C. saturable reactor as disclosed in Specification 610,061.

Abstract: Crude adipic acid is purified by passing an aqueous solution of the crude acid through a filter having a pore size of 1 to 15m  and crystallising the acid from the filtrate.  If desired, active carbon, kieselguhr or other adsorption active additive or a filtration auxiliary such as shredded cellulose acetate may be used in the filtration.  A diaphragm of polytetrafluoroethylene or polytrifluoro-mono-chloroethylene may be used as the filter of specified pore size.  The solution may first be passed through a filter having a mesh size of at least 20m , e.g., 20-100m .  The solution may be passed through an ion-exchanger before or after the ultra fine filtration.
