Title: Improvements in or relating to the production of synthetic resin-fatty oil compositions
Filed: 1943-12-23
Abstract: Resin fatty oil compositions comprise an oil soluble thermo hardening amine modified phenol-aldehyde resin dissolved or dispersed in a fatty oil, i.e. hydroxylated fatty acid glycerides containing a free hydroxyl group, e.g. blown linseed oil, blown or ordinary castor oil. The amine modified phenol aldehyde resin is obtained by reacting cresol, xylenol, or commercial mixtures thereof with formaldehyde in the presence of a primary or secondary amine or cycloaliphatic amine of from 25 per cent by weight of the phenolic compound up to 2 mols amine per 1 mol phenol in presence of an acid catalyst or an alkaline catalyst other than said amine.  The formaldehyde may be replaced by its condensation products with ammonia and hexamethylenetetramine in which case the addition of a separate catalyst is unnecessary. The amines may be used in the form of free bases or of their salts and mixtures of amines may be used the oil solubility increasing and the hardening speed being reduced with increase in the amount of amine used.  The resin may be obtained by reacting 100 parts (by weight) commercial cresol, 50 parts cyclohexylamine, 100 parts 40 per cent formalin and 5 parts .880 ammonia for 60 mins. under reflux, distilling off water, heating for 15 mins. at 130 DEG  C. and cooling.  The product melts at 71 DEG  C. and when mixed with 4 parts blown linseed oil gels on heating to 140 DEG  C. in 8 mins.  Quick drying varnishes are obtained by mixing the composition with vulcanising agents, accelerators, driers and thinners (white spirit, xylol, solvent naphtha).  An amine modified resin is obtained by reacting cresol, aniline, formalin in presence of ammonia and 10 parts of the resin are mixed with 100 parts blown linseed oil the product being suitable as a rubber substitute.

Abstract: 405,331. Valve generating, modulating, and detecting circuits. INTERNATIONAL COMMUNICATIONS LABORATORIES, Inc., 200, Mount Pleasant Avenue, Newark, New Jersey, U.S.A., and CLAVIER, A. G., 46, Avenue de Breteuil, Paris. Aug. 4, 1932, No. 21888. [Class 40 (v).] An ultra-short-wave valve oscillator 1 of the vibrating electron type is utilized for modulation and demodulation by applying the modulating voltage (or the incoming modulated wave) to a potentiometer 12, connected across the cathode 2 and the high-voltage grid 3, whilst a tap 14 on the potentiometer is connected to the low-voltage plate 4. Direct voltages are applied to the electrodes 4, 3 from sources 7, 8 through chokes 9, 10 and the modulating or demodulating voltages are applied through condensers 13, 14. By using a selected ratio for the tapped potentiometer, the frequency of the oscillator remains constant. The specification includes curves showing the relation between grid and plate voltages for obtaining constant frequency ; and other curves showing the wave amplitude as a function of the grid voltage under constant frequency conditions. For modulation a straight portion of the latter curve is used, whilst for demodulation, operation is effected at a point where the amplitude is zero, i.e. where the valve is on the verge of oscillation.
