Abstract: Compounds of formula <FORM:1020291/C3/1> where X is the residue of a thiocarboxylic acid (i.e. containing S in the carboxyl group) and Z is sulphur when Y is the residue of an alkyl, aryl or aralkyl mercaptan or a mercaptocarboxylic acid ester, and either sulphur or oxygen when Y is the residue of an alpha, beta or gamma mercaptocarboxylic acid or an ester thereof, are used as stabilizers in chlorine containing synthetic resin compositions, especially PVC or a PVC/polyvinyl acetate copolymer.ALSO:The invention comprises diorganotin compounds of formula <FORM:1020291/C2/1> where X is the residue of a thiocarboxylic acid as defined and Z is sulphur when Y is the residue of an alkyl, aryl or aralkyl mercaptan or a mercapto carboxylic acid ester and either sulphur or oxygen when Y is the residue of an alpha, beta or gamma mercapto carboxylic acid or an ester thereof.  "Thiocarboxylic acid" is used to mean a carboxylic acid containing sulphur in the carboxylic group e.g. COSH: a "mercapto carboxylic acid" contains both -SH and -COOH groups in the molecule. Thiobenzoic acid is the preferred thiocarboxylic acid.  The R groups may be alkyl, aryl, alkaryl or aralkyl and may be the same or different. The compounds may be prepared from diorganotin halides or stannones by known methods.  Compounds specified include dibutyl tin thiobenzoate/lauryl mercaptide, dibutyltin thiobenzoate/2 - ethyl hexyl mercaptoacetate and dibutyltin thiobenzoate/b  - mercaptopropionate.

Title: An improved wheel guard and obstruction remover for road vehicles
IPC: B60R21/34
Filed: 1919-07-09
Abstract: 152,124. Mallins, C. W. July 9, 1919. Wheel guards and obstruction-removers.-Relates to life-guards for road vehicles of the type comprising front and rear guards held with their front edges just clear of the ground, the front guard normally serving to catch an obstructing body, but, should the body pass beneath it, being arranged to actuate trip mechanism for lowering the rear guard. According to the invention, the front and rear guards A, A<1>, Fig. 3, are combined in one curved tubular frame pivoted at D on arms B carried by the axle C. A spring E is connected by a curved arm E<1> to a lever F connected to the axis D. and, in the normal position of the guard shown in Fig. 3, its line of action passes below the axis D; when, however, an obstruction passes below and lifts the front guard A, the lie of action of the spring E passes above the axis D, and the spring aids in the depression of the rear guard A<1>. An auxiliary guard G, Fig. 6, may be pivoted to the main guard on the axis D and arranged to swing forwardly to give access to the starting-handle. Instead of being attached rigidly to the axle C, the guard may be pivoted centrally thereon, and arranged to turn laterally with the wheels in steering. Separate guards are provided for the wheels of the vehicle.

Title: A welding dynamo
IPC: H02K23/02
Filed: 1950-07-10
Abstract: 680,166. Dynamo-electric machines; electric supply systems. CESKOSLOVENSKE ZAVODY TEZKEHO STROJIRENSTVE NARODNI PODNIK, and SVOBODA, V. July 10, 1950, No. 17204/50. Classes 35 and 38 (iv). A welding generator is excited in such a way that up to a certain load current it is separately excited, and at greater loads a regulating device is brought into action employing two opposing voltages, one of which is constant and adjustable and the other is proportional to the load current or voltage, so as to limit the shortcircuit current. In one form, Fig. 2, the generator 1 with welding terminals 4 is excited by an exciter 8 feeding field. winding 6, whilst the regulation is achieved by a bucking field winding 7 fed from a further exciter 9 and the voltage appearing across quadrature brushes 5 of the welding generator. This voltage, being dependent on armature reaction, is proportional to the welding current, and when it rises above that of the exciter 9, current passes through rectifier 10 to reduce the excitation of the welding generator and so limit the short-circuit current. In a modified form, Fig. 3, the exciting winding 6 is fed from A.C. mains 13 through a discharge tube 12. The grid 14 of the tube is energized with A.C. voltage from a transformer 15 and a pair of opposing adjustable D.C. voltages Eg<SP>1</SP> and Eg<SP>2</SP>. These voltages are derived from a battery 16 through potentiometer 17, and from a series resistance 5<SP>1</SP> in the welding generator load circuit through potentiometer 18 respectively. For values of load current below a certain value, the resultant difference between voltages Eg<SP>1</SP> and Eg<SP>2</SP> is greater than the peak voltage derived from the transformer 15 so that no regulation of the ignition of the tube and the excitation of winding 6 is unaffected. At a certain load current, however, the voltage Eg<SP>2</SP> exceeds Eg<SP>1</SP> and their difference is less than the peak A.C. voltage from the transformer. This causes the ignition of each cycle to be delayed and the excitation is reduced to limit the short-circuit current. The value of current maximum is controlled by potentiometer 17 whilst the slope of the characteristic may be controlled by potentiometer 18 or by tappings on transformer 15. In a modification, not shown, the slope of the characteristic is increased by connecting a further discharge tube across the exciting winding and controlled to ignite late in each current wave. In a further modification, also not shown, the control voltage dependent on the machine load is derived directly from the output brushes and not from quadrature brushes or a series resistance.

Abstract: Monoisopropylbiphenyl for use as a coolant and moderator in a nuclear reactor (see Group XL(a)) is prepared by adding anhydrous aluminium chloride catalyst to molten biphenyl, heating to 75 DEG -80 DEG C. saturating with hydrogen chloride, and then passing in propylene gas. The reaction product is cooled, mixed with water, and the organic layer separated and washed with sodium chloride solution.  A mixture of para and meta isomers is obtained by fractional distillation.ALSO:A coolant and moderator circulating between a heat exchanger and a nuclear reactor (see Group XL(a)) consists of isopropylbiphenyl or a mixture of this substance with biphenyl. Preferably the liquid has a freezing point of 20 DEG C. or lower and contains at least 80% by weight of a mixture of the meta and para isomers of isopropylbiphenyl.  This liquid is more effective as a moderator and coolant than biphenyl alone, having a lower freezing point and a higher specific heat; free radicals formed by radiolytic decomposition are removed by the isopropylbiphenyl.
