Filed: 1929-09-03
Abstract: 339,287. Nippon Gaishi Kabushiki Kaisha. Jan. 22, 1929, [Convention date]. Insulators.-An insulator of the type in which a cap and a pin are secured by helical springs to the insulator body, is formed with openings on enlarged portions of the cap and pin, the springs being forced into position in grooves in the parts to be joined through the openings on the cap and pin. In the embodiment a suspension insulator- 1 is fitted with a cap 2 and pin 3. The lower edge 4 of the cap 2 is rounded, and the insulator neck grooved, to form a circular ring space 8. An opening 6 is provided in the cap edge and is adapted to allow a coiled spring wire 7 to be forced through the opening 6 into the space 8. The insulator pin hole is formed with a groove 9 and an annular groove 10 is formed at the top of the pin 3. A portion 11 of the pin neck is cut away to form an opening through which a coiled spring 7 of phosphor bronze or piano wire may be placed in position in the circular ring space formed by the. grooves 9, 10.

Title: Process for preparing detergent bars
IPC: C11D1/16
Filed: 1961-07-25
Abstract: <PICT:0942045/C3/1> Detergent bars are made from a flowable mass comprising, by weight, 15-25% alkyl glyceryl ether sulphonate and 60-40% alkali metal soap by subjecting the heated mass while in a non-crystalline state to high shear mixing to homogenize the mixture, and thereafter, until the finished detergent bars are obtained, maintaining the temperature outside the range 110-120 DEG  F. for a time sufficient to ensure non-preferential crystallization of the detergent components from the mixture.  It is preferred that the soap consist of substantially equal weights of sodium coconut oil and tallow soaps and that the weight ratio of soap to sulphonate be substantially 2 : 1, 10-30% of the alkyl glyceryl ether sulphonate may be present in the dimeric form. A favoured composition consists of 46% soap, 23% sodium alkyl glyceryl ether sulphonate, 2% glycerol, 1-2% sodium chloride, 23% moisture, and minor amounts of perfume, silicates, and preservative.  The composition may be aerated to provide floating bars.  As shown, the mixture from crutcher 1 is pumped through high shear homogenizing valve 3, the pressure drop across which is preferably 500-1500 p.s.i.g.  The mixture passes to heater 4 where it is raised to 390-415 DEG  F., and thence to flash chamber 6 before being pumped to crutcher 10 where other additives may be incorporated and the mixture aerated if desired. The mixture is agitated and cooled in device 11 to 120-160 DEG  F., preferably 140-145 DEG  F., and is extruded at 12 and cut into bars by cutter 14. The bars are then cooled to 75 DEG  F. at 80% relative humidity, under which conditions the bars are at a temperature of 110-120 DEG F. for less than 15 minutes; the avoidance of this temperature range is stated to prevent mottling. Specifications 555,034 and 935,200 are referred to.

Title: Process for the manufacture of phosphate-containing fertilizers
IPC: C05B11/06
Filed: 1951-11-16
Abstract: A fertilizer consisting mainly of dicalcium phosphate is prepared by treating raw phosphates with a mixture of nitric acid and sulphuric and/or phosphoric acid, followed, after the decomposition has taken place, by heating to a temperature above 100 DEG C. but below 200 DEG C. thereby removing the nitrogen content substantially completely (i.e. below 3 per cent. preferably below 1 per cent.).  The reactant acids are preferably employed in amounts proportionate to their equivalent weights and if sulphuric acid be employed, gypsum may be separated before the heating step.

A reinforcing yarn comprises an encapsulated multifilament low-twist yarn (as defined) formed from a regenerated or synthetic polymeric material in which the encapsulating material is an elastic solid having a Poissons ratio of at least 0.45 under tensile strains not greater than 5% and penetrating the whole of the yarn outer surface to a depth at least sufficient to bond together 30% of the filaments of the yarn. The elastic solid may be derived from a resorcinol-formaldehyde-latex adhesive composition which may contain butadiene, vinyl pyridine or natural rubber, and the yarn may be of rayon, nylon, polyester or polyvinyl alcohol. In the manufacture of the reinforcing yarn, a multifilament low-twist yarn is coated with a liquid which can subsequently be converted to an elastic solid having a Poissons ratio of at least 0.45 under tensile strains not greater than 5%, the depth of penetration being at least sufficient to bond together 30% of the filaments of the yarn, and the liquid is then converted into the elastic solid. In a preferred embodiment, at least two multifilament yarns are coated with the liquid and twisted together prior to the conversion of the liquid into the elastic solid. The liquid may be a solution of a polymer in an organic solvent, a solution of cis-polyisoprene in nhexane containing dicumyl peroxide or a liquid polyurethane. In a preferred embodiment the multifilament yarn is pre-treated with an adhesive. The yarns are preferably used to make cords for use in the manufacture of pneumatic tyres.

Abstract: 191,704. Motte, G. Jan. 13, 1922, [Convention date]. Void [Published under Sect. 91 of the Act]. Uniting and dividing by fusion.-In an electrical process for welding and cutting, the bringing together and proportioning of the substances used in the operations varies with the progress of the operation, the substances being supplied continuously, and their nature and proportions being varied as desired. An electric conductor 1 wound on a drum 2 is fed' by motor-driven rollers 4 through a tube 3 having an extension 13 of flexible hose provided at the outer end with an operating handle 12 and a roller 14 which may adhere to the work magnetically. The rollers 4 supply current to the electrode and may be situated at the delivery end of the tube 3. The speed of the rollers is automatically regulated by the arc current acting directly or through the medium of an electromagnet on the excitation regulator of the feed-motor. Alternatively the welding current may energise an electromagnet controlling a friction-clutch fitted to the rollers 4. The electrode is coated automatically during its progress through the tube 3 by a strip of material 8 drawn off the reel 9 bv rollers 10. The strip may be wound on the electrode by a device similar to those used in making electric cables or the electrode 1 may be rotated during feeding. In some cases the strip 8 may be the electric conductor, in which cases the current is supplied to the rollers 10. The tube 3 has a branch 11 through which solids or liquids may be introduced. The apparatus may be used for overhead or under-water operations by supplying an active or inert gas through the branch 11, and work may be done in an explosive atmosphere if an inert gas is used. The arc may be directed by a magnetic field. The tube 3, rollers 4, 10 and drums 2, 9 are enclosed in a casing 21 which may be suspended from a pulley block or mounted on wheels. The operating handle 12 is provided with a lever 23 controlling the operation of the feed rollers and may be connected to the sliderest of a lathe for automatically depositing metal on a shaft. In the arrangement shown in Fig. 2, the tubes 3 are provided with cylinders 24 containing pastes supplied to the tubes under pressure by pistons 15. The apparatus may be used for cutting refractory materials.
