Title: Improvement in preserving rubber and other oxidisable organic substances
IPC: C11B5/00
Filed: 1942-08-05
Abstract: Rubber and other oxidizable organic substances are preserved by incorporating a compound having the formula Ar-NH-Ar1-O-Y-COOX, where Ar, Ar1 and Y are aromatic radicals and X is hydrogen or an element forming salts with acids, e.g. Zn, Ca, Mg, Na, NH4 or NH2(CH3)2. Such compounds include arylamino-aryloxy-aromatic or arylalkyl carboxylic acids, and their metal, ammonium, and alkyl-ammonium salts which may contain more than one carboxyl group.  They can be prepared by reacting a hydroxy-diarylamine with a halogen substituted aromatic acid in the presence of alkali.  Zinc salts, made by mixing the sodium salts with zinc sulphate solution, are particularly useful in milled rubber, and ammonium or alkyl ammonium salts in latex, the amounts being from 0.1 to 3 per cent by weight of the rubber.  An example shows the effect on tensile strength and elongation of the addition to a white stock of 0.5 parts of p-(4-carboxy-benzyloxy)-diphenylamine per 100 parts of rubber.  In addition to natural and synthetic rubber and allied gums, reference is made to the use of the preservatives in fatty and petroleum oils, soaps, aldehydes, synthetic resins, and turpentine.ALSO:Rubber and other oxidizable organic substances are preserved by incorporating a compound having the formula Ar-NH-Ar1-O-Y-COOX where Ar, Ar1, and Y are aromatic radicals and X is hydrogen or an element forming salts with acids, e.g. Zn, Ca, Mg, Na, NH4 or NH2(CH3)2.

Title: Reactive power compensator for electrical power transmission systems
IPC: H02J3/18
Filed: 1974-03-12
Abstract: 1456575 Automatic control of power transmission BBC BROWN BOVERI & CO Ltd 2 March 1974 [14 March 1973] 10978/74 Heading G3R [Also in Division H2]  An adjustable reactive power compensator for a single phase or polyphase electrical transmission line f, comprises a reactive transformer having an excitation winding a for connection to the line and a power winding a' connected to an adjustable reactive element b which element is connected to a control device e for deriving an error signal representing a deviation from a normal value of a line parameter whereby the reactance of the element is adjusted to compensate for the deviation. The parameter may be the line voltage which is measured by a device g and fed to the control device e where it is compared with a reference value to produce an error signal. The error signal controls the reactance of the element b and switches a capacitor bank c until the measured value approaches the reference value to maintain the line voltage constant. The control is assisted by the transformer since saturation occurs when the voltage rises above a predetermined value thereby additionally increasing the reactive power consumption. The element b may consist of one or a combination of arrangements such as synchronous phase shifters, thyristor controlled capacitors or chokes, mains commutated converters, artifically commutated reactive power converters, choke coils (transductors) controlled by D.C. magnetic bias, chokes or capacitors connected to step switches or a regulating transformer.
