Title: Coagulation of dissolved elastomers
IPC: C08C2/06
Filed: 1965-08-20
Abstract: A solution in an organic solvent immiscible with water of an elastomer or mixture of elastomers containing a pigment dispersed therein is passed with water to a mechanical mixing zone where it is formed into an emulsion by violent mechanical agitation; the emulsion is then introduced into a vigorously agitated body of hot water contained in a coagulation zone and maintained at a temperature above the boiling-point of said organic solvent or its azeotrope with water, to thereby contact said solution with hot water and vaporize said organic solvent to produce a particulate coagulum of elastomer containing said pigment in a uniformly dispersed state.  The process is particularly applicable to butyl rubber, polybutadiene rubber, a mixture of polybutadiene rubber and SBR, and ethylene-propylene-dicyclopentadiene rubber solutions all containing carbon black.  The solutions may also contain processing oil.

Abstract: 977,693. Transistor amplifying circuits; amplitude modulating systems. RACAL ELECTRONICS Ltd. Oct. 20, 1961 [Oct. 21, 1960], No. 36200/60. Headings H3R and H3T. In an amplifier of the type in which the signal to be amplified is modulated on to a carrier of higher frequency, modulation is performed by a bridge network comprising two resistive arms R 1 , R 2  and two arms each comprising an inductance L 1 , L 2  respectively, series resonant with a potential variable capacitor D 1 , D 2  respectively. The potential variable capacitors comprise oppositely poled diodes biased by means of voltage sources B 1 , B 2  respectively. The carrier frequency V 0 , f 0  of constant amplitude is applied across one diagonal of the bridge and the modulated output V 1 , V 2  taken from the other, the signal dv to be amplified being injected between the bridge network and earth and causing the capacity of the diodes D 1 , D 2  to vary in opposite directions. The resistive arms may be replaced by capacitors and the series resonant circuits may alternatively be replaced by parallel resonant circuits. When the arrangement feeds into a transistor amplifier it may be coupled into the amplifier by means of a tuned transformer with a screened primary winding.
