Title: Improvements in or relating to the manufacture of interpolymers of acenaphthylene
Inventor: ARMITAGE FRANK
Filed: 1949-08-05
Abstract: Acenaphthylene or a nuclear halogen or alkyl, e.g. methyl, ethyl, chloro or fluoro substitution derivative is interpolymerized with one or more polyhydric alcoholic esters, in the absence of styrene, by heating the mixture.  The polyhydric alcoholic esters are obtained by the esterification of one or more polyhydric alcohols with one or more monobasic carboxylic acids only, at least one of which acids contains ethylenic unsaturation, preferably conjugated and either a diene or triene fatty oil acid, the other or others being either saturated or unsaturated carboxylic acids, e.g. sorbic, cinnamic, acrylic acids or linseed, tung, dehydrated castor, perilla, sunflower, soybean, safflower seed, fish, cotton-seed, corn or oiticica oil acids.  A solution in, e.g. xylol, may be heated under reflux, together with modifiers, such as monocyclic a -terpenes, dipentene, sulphur and phenol, catalysts, e.g. hydrogen and benzoyl peroxides and hydroperoxides, aluminium chloride, or activated clay, and air or oxygen may be blown through the mixture.  The acenaphthylene may be added continuously or discontinuously in portions throughout the reaction period.  Examples show acenaphthylene interpolymerized with conjugated linseed oil alone, or admixed with raw china wood oil, with or without dipentene; dehydrated castor oil, and china wood oil.  Driers, e.g. cobalt naphthenate, pigments, e.g. titanium dioxide, and solvents, e.g. aromatic white spirits, may be added to produce varnishes and paints.

Abstract: 1,031,616. Gas turbine plant; power plant. INTERNATIONAL RESEARCH & DEVELOPMENT CO. Ltd. April 28, 1965 [May 30, 1964; Sept. 3, 1964], Nos. 20866/64 and 36154/64. Headings F1G and F1Q. The invention relates to a closed cycle gas turbine plant in which the gas in the closed cycle is cooled before admission to the compressor by heat exchange with liquefied natural gas, the liquefied natural gas being thereby changed back to the gaseous state. In the plant shown the working fluid of the closed cycle plant is helium which is first cooled in a pre-cooler 5 and then compressed in a compressor 1. The helium under pressure is then heated in a heater 6 and then further heated in a heater 7 before passing into a turbine 2 which drives the compressor 1. The helium is then further expanded in a second, useful power turbine 3 which drives an electric generator 4. The helium discharging from the turbine 3 is cooled in the heat exchanger 6 and then further cooled in the pre-cooler 5. Liquefied natural gas from the reservoir 8 is delivered by pump 10 through the heat exchanger 5 wherein the liquefied natural gas is heated and changed back to the gaseous state and the helium in the closed circuit is cooled. The natural gas in the gaseous state is supplied to a gas line. A portion of the natural gas in the gaseous state passes to the combustion chamber 9, the combustion products from which pass through the heat exchanger 7 to heat the helium before admission to the turbine 7.
