Abstract: 1,254,004. Copolyamides. IMPERIAL CHEMICAL INDUSTRIES Ltd. 14 April, 1970 [2 May, 1969], No. 22508/69. Headings C3C and C3R. Copolyamides of reduced viscosity at least 0-5 consist essentially of repeat units A represents -CH 2 (CR 1 R 2 ) m CH 2 -, where R i  and R 2  are H or C 1-4  alkyl and m is 0 to 10 in 4 to 20% of the units and -C 6 H 4 -SO 2 -C 6 H 4 - is the remainder while B is a direct link or divalent organic group and is -(CH 2 ) n -, where n is 4 to 14 in at least 75% of the units. They may be prepared by co-condensing a bis(4- aminophenyl) sulphone and an appropriate diaminoalkane with an appropriate dicarboxylic acid or acids conveniently by the process of Specifications 1,254,003 and 1,254,007. Matter claimed in Specification 1,254,005 is disclaimed. Up to 5 mole per cent of monofunctional chain terminators, e.g. monoaminodiphenyl sulphones or benzyl, n-hexyl, n-decyi or n-octadecyi amine, or polyfunctional chain branching agents, e.g. 4,4<SP>1</SP> - diaminodiphenylamine, 2,4,41 - triaminodiphenyl sulphone or 3,31-diaminobenzidine may be included. Numerous suitable diamines and diacids for the essential units are listed. The products may be modified to reduce acidity by reaction with an isocyanate, epoxide and/or monofunetional primary or secondary amine while amine ends may be neutralized by acylation, e.g. with acetyl chloride. Additives such as heat and light stabilizers, lubricants, plasticizers, pigments, dyes, mould release agents and fillers, e.g. glass, asbestos or carbon fibres, powdered glass, metals or metal oxides, graphite, carbon black or molybdenum disulphide may be included in the polymers. The polymers are stated to be generally amorphous non-crystallizable tough thermoplasts of high softening points with better colour and lower melt viscosity than the corresponding bis-(aminophenyl) sulphone homopolymers. They may be hot shaped to films, fibres and other articles by extrusion, moulding or vacuum-forming. Films and fibres may also be obtained from solutions, e.g. in dimethyl formamide, acetamide or sulphoxide, N-methyl pyrrolidone, tetramethylene sulphone, tetramethyl urea or hexamethyl phosphoramide. Solutions or organic or aqueous dispersions may also be used as adhesives or coatings or varnishes for wires or fabrics. Specified applications of the polymers include dielectric film for slot liners in electric motors and insulation in transformers, capacitors or cables; corrosion resistant pipes and containers; and fibres woven into fabric for use in protective clothing, filters or electrical sheathing. Foamed polymers may be obtained by controlled flow of nitrogen through the melt during polymerization. Reference is made to Specification 1,161,124.

In treating seeds of legumes, e.g. soybeans, chick peas and like hull-enclosed cotyledon seeds, to improve their edibility, the seeds are dry-heated throughout each seed, as by hot air, or hot combustion gases associated with a flame, at a temperature betwen 175‹ and 500‹F. for 10 seconds to 60 minutes, so as to split the hulls, and the seeds, e.g. still hot, are then leached with water, in which they are preferably agitated, to swell the cotyledons and detach the hulls and also, if desired, the hypocotyls (hearts), and extract undesired flavours and sugars. The dehulled and swollen seeds are then removed from the leaching water and dried, e.g. in a current of air at 175‹F. or 425‹F.; or roasted, e.g. in hot air at 325‹F., or in edible oil at 300‹F., and may then be ground to yield a flour, or ground with ingredients selected from: edible oils, sugars, salt, flavourings and stabilizers, to yield a food paste or spread.

Title: Improvements relating to windscreen wipers for motor vehicles
IPC: B60S1/18
Filed: 1935-08-13
Abstract: 461,255. Windscreen-cleaners. LUCAS, Ltd., J., WATSON, E. A., ROBINSON, E. H. C., and HUYTON, A. Aug. 13, 1935, No. 22774. [Class 138 (i)] Operating mechanism for a windscreencleaner comprises a driving member, a driven member capable of lateral movement relatively to the driving member, and a crank or equivalent means associated with the driven member for actuating an oscillatory wiper arm or arms, so that with the driven member in one extreme lateral position, the arm is oscillated between suitable limits on the screen whilst with the driven member in the other extreme lateral position the arm can be brought to rest in an unobstructive position. In the construction shown in Figs. 1 and 2, a worm a driven by a flexible shaft d engages a worm wheel b, the spindle of which carries a crank c connected by a rod g and crank f to an oscillatory wiper arm. The worm wheel b and its spindle e are carried by a slide l which is capable of being displaced within limits determined by a slot n, displacement being effected by means of an eccentric p on a shaft q provided with a finger piece. The shaft q also carries a cam s adapted to actuate a lever j which is connected by a cable t to a clutch (not shown). Fig. 2 shows the position of the mechanism when the wiper is operating. To stop the wiper, the finger piece is rotated so that the cam s permits the lever j to be actuated by a spring k. The end of the lever rides on a disc h secured to the spindle e and eventually falls into a notch i, whereupon the cable t declutches the flexible shaft d from its drive. The worm wheel b is moved to the left at the same time so that the wiper arm is brought to rest in a horizontal position indicated by 1. In a modification shown in Fig. 4, the spindle e of the worm wheel b is carried by a slide l which is formed with a slot w for engaging a crank v on the spindle q fitted with a finger piece. The spindle e carries a cam x which is adapted to operate an electric switch z whereby the driving mechanism is declutched electromagnetically when the wiper is moved to its horizontal position. In a further modification shown in Figs. 7 and 9, the worm wheel b is not capable of displacement, but is connected to a crank 6 secured to a hollow spindle 7 to which is also secured the crank c operatively connected to the wiper arm. Within the spindle 7 is a shaft 8 provided with a finger piece r, the shaft at its inner end having an eccentric 9 carried by the casing m. To the eccentric is secured a cam 10 adapted to act on the lever j. The wiper is inoperative with the mechanism in the position shown. When the finger piece r is rotated the shaft 8 and spindle 7 are displaced whereby the wiper arm is moved to a position at one end of its normal traverse, and the lever j is operated to cause engagement of the clutch and permit rotation of the worm wheel b to effect the oscillation of the wiper. U.S.A. Specification 1,906,047 is referred to.

Abstract: 615,763. Electric gauges. BIRMINGHAM SMALL ARMS CO., Ltd., and WALTON, K. July 31, 1946, No. 22776. [Class 37] A device for measuring the thickness of a non- magnetic coating on a magnetic base comprises an electromagnet 17, the core 7 of which is biassed upwardly by a spring 11, and a coaxial plunger 25 also biassed upwardly by a spring 33, the core and plunger normally contacting one another at contacts 39, 41 as shown in Fig. 1. In operation, the D.C. through the coil 17 is first adjusted at 59 to a maximum. The core 7 is then forced downwardly by means of the handle 37 into engagement with the work being gauged where it is held by the electromagnet. The handle 37 is then released and breaks the circuit of a normally lit lamp 73 at contacts 39, 41. The current in coil 17 is then gradually reduced by adjusting resistor 59 until the spring 11 pulls the core 7 away from the work, when the lamp 73 is relit. The current flow at this instant is a measure of the non-magnetic coating thickness and is read on the meter 55 which may be graduated to read thickness direct. A variable resistor 6 is used to compensate for ageing of the supply battery 53 and the meter may be shunted by an adjustable resistor to cater for a plurality of thickness ranges.
