Title: Interpolymers of oxidized drying oils and alkenyl aromatic compounds and compositions comprising same
IPC: C09D125/14
Filed: 1949-02-03
Abstract: Toluene-soluble resins are made by copolymerizing at elevated temperatures a monovinyl aromatic hydrocarbon having less than 12 carbon atoms in the molecule, a mono-alpha-alkyl vinyl aromatic hydrocarbon containing less than 13 carbon atoms in the molecule and having less than 5 carbon atoms in the alkyl-vinyl group, and a drying oil which in its raw state has a degree of conjugation not greater than 25 per cent and which has been oxidized by an oxygen-containing gas so that its combined oxygen content is increased by at least 10 per cent, the proportions being from 80 to 20 parts of the oxidized drying oil and from 20 to 80 parts of a mixture consisting of from 10 to 40 per cent of the alpha-alkyl vinyl compound and from 90 to 60 per cent of the monovinyl compound. Polymerization is preferably effected en masse at temperatures between 100 DEG  and 300 DEG  C. in the presence of an organic peroxide catalyst such as benzoyl, lauroyl, or acetyl peroxide.  If desired, either or both alkenyl aromatic reactants may be added gradually to the heated oil.  Solvents such as benzene, toluene, ethylbenzene and xylene may be, but are preferably, not used. Suitable monovinyl compounds are styrene, o-, m-, and p-methyl and ethyl styrenes, ar-monoisopropyl styrene, ar-methyl-ar-ethyl styrenes and ar-dimethyl styrenes.  Mixtures of two or more may be used. Specified alkyl vinyl compounds are a -methyl styrene, a  - ethyl styrene, ar - methyl - alpha-methyl styrenes, ar-dimethyl-alpha-methyl styrenes, ar - ethyl - alpha - methyl styrenes and ar-isopropyl alpha-methyl styrenes. Suitable drying oils are linseed, soyabean, dehydrated castor and sardine oils.  Mixtures of these or with highly conjugated oils may be used provided that the average degree of conjugation is not greater than 25 per cent.  The oils may contain minor amounts of the free acids or of mono- or di-glycerides of the acids. Synthetic oils such as ethylene glycol or propylene glycol esters of drying oil fatty acids may also be used. The oil is oxidized by blowing air, oxygen or oxygen-containing gas through the oil heated to temperatures of from 50 DEG  to 300 DEG  C. After polymerization, the unreacted material may be removed by treatment with steam or by heating under vacuum.  The gummy or resinous copolymers are soluble in paint and varnish solvents such as benzene, toluene, xylene, mineral spirits and the material known under the Registered Trade Mark "Solvesso."  Driers such as lead and cobalt naphthenates and pigments may be added and the compositions form films which dry in air, apparently undergoing oxidation to form hard tack-free coatings.  Specifications 573,835, [Group IV (b)], 621,542 and U.S.A. Specification 1,975,959 are referred to.

Abstract: 1,042,773. Valves. GIRLING Ltd. Sept. 19, 1963 [Sept. 27, 1962], No. 3064/65. Divided out of 1,042,772. Heading F2V. A valve for controlling the relative fluid pressures in the two chambers of a cylinder 44 comprises a first closure member 55 supported on diaphragms 56 and 57 and a second closure member 52, both members being urged by springs 59, 53 towards the right. In the position shown, the two parts of the cylinder 44 are interconnected through pipes 46, 47 and a port 61 and are also connected by port 45 to vacuum. When air from a control device enters the valve housing through a port 51, member 55 moves to the left to seat on member 52 and break the communication between the two parts of the cylinder. A further increase in the air pressure causes the member 55 to move member 52 away from its seat 54, so permitting atmospheric air to pass from ports 49 to the left-hand end of the cylinder 44 to move the piston therein to the right.

Abstract: 1437913 Transistor amplifying circuits TRW Inc 23 Jan 1974 [29 May 1973] 03067/74 In a push-pull amplifier, in-phase components in the output are fed back to the input in parallel with the input signals. An input stage comprises transistors 31, 33 driven in push-pull by means of input transformer 35 and thus drives an output stage comprising transistors 32, 34 in common base connection. Output is obtained via output transformer 44. The bases of transistors 32, 34 are connected together and biased via resistor 44, while the bases of transistors 31, 35 are biased over the resistance network 45, 46, 47, 48. Any unbalance produces a signal at the common bases of transistors 32, 34 and this is fed back via the capacitor 49 in such a way as to reduce the unbalance.

Abstract: 868,407. Alternators; supply systems depending on variable speed generators. BETEILIGUNGSUND PATENTVERWALTUNGSG.m.b.H. Jan. 28, 1960 [Feb. 2, 1959], No. 3132/60. Classes 35 and 38 (4). An alternator 1 which is driven from the wheels of a refrigerated wagon is compoundexcited in such a way that the refrigerator motors 16 operate at constant torque irrespective of the wagon speed. This is achieved by feeding the shunt excitation winding through air-gap chokes 8 which maintain this field current constant irrespective of speed, and using current compounding 11, 9 to off-set the effects of load. Thus the voltage generator is proportional to the frequency, and the motors operate at constant torque. The current compounding rectifier may be in the primary 12 or secondary 14 of the motor transformer, or it may be in the star-point of the generator, or of the motors, the transformer being dispensed with in this case.
