Title: Arc chutes for electric switches or circuit breakers
Inventor: WHITNEY WILLIS BEVAN
IPC: H01H9/36
Filed: 1951-03-20
Abstract: 715,748. Arc-rupturing in switches. BRITISH ELECTRICAL & ALLIED INDUSTRIES RESEARCH ASSOCIATION. March 20, 1952 [March. 20, 1951], No. 6692/51. Class 38(5) In an arc-chute good heat transfer is obtained by providing surfaces of metal laminated with insulation so that the laminae are substantially normal to the adjacent path of the arc. The arc chute is of the kind in which the arc is blown upwardly by a magnetic field and forced to assume a sinous path by interleaved arc barriers and the barriers are formed by metallic laminations 14 separated by plates of dielectric and secured on solid cores 15 of heat resisting insulating material. The inner ends of each core 15 forms a T-piece 16 which assists in securing the laminae. The metal laminations are so thin that the voltage drop per lamination in the gaseous arc path adjacent the laminations is not sufficient to cause the arc to root onto the metal. The metal laminations may be of copper and the insulation between them of mica or vitreous enamel, the latter also serving as a mechanical bond. Alternatively the metal laminae may be insulated from each other by oxide layers on their surfaces or by simple air gaps formed by spacing the laminae apart.

Patent GB-612527-A (GB)
Title: A process for improving the crease-resistance of textile material
IPC: D06M15/693
Filed: 1946-03-04
Abstract: Tetrahydronaphthalene hydroperoxide is prepared by bubbling air through tetrahydronaphthalene at 50 DEG  C., finely dispersed copper bronze being used as a catalyst.  After 18 hours, the catalyst is filtered off, the solution cooled to -20 DEG  C., the crystalline hydroperoxide separated, washed with pentane and recrystallised from gasoline.ALSO:Textile material is treated with a solution of the water-soluble unsaturated product obtained by reacting an alkaline substance with a product manufactured from natural rubber, gutta-percha, balata or other rubber-like natural substances with sulphur dioxide, and subsequently exposing the treated material to the action of sulphur dioxide to improve its resistance to creasing. Suitable alkaline substances are the alkali metal hydroxides or carbonates or organic bases such as triethanolamine, aniline or pyridine.  Heat and organic dispersing agents such as alcohol or ether may be employed to effect the reaction.  The sulphur dioxide used in the second step may be in the gaseous, liquid or dissolved state, and its action may be accelerated by the addition of hydroperoxides such as tetrahydronaphthalene hydroperoxide, peracetic acid and hydrogen peroxide.  The solution used for impregnation may be purified prior to use by the addition of dilute mineral acid and the so-produced coagulum used in a neutral or weakly alkaline solution.  The textile material after treatment has increased crease resistance, improved feel and increased water-repellent properties. In an example, 20 g. of a p  rubber-sulphur dioxide product (S content 11.3 per cent) is boiled with 200 c.c. of 3.6N.  KOH and 800 c.c. of methanol.  The liquid is neutralized with 2N.H2SO4 in excess, precipitating a coagulum which is then dissolved in dilute alkali to give a 5 per cent solution.  120 c.c. of this solution to which 8 c.c. of 40 per cent hydrogen peroxide are added is used to impregnate a rayon fabric, which after treatment, is exposed to sulphur dioxide for 15 minutes at 25 DEG  C.  Specification 608,922, [Group V], is referred to.  The Specification as open to inspection under Sect. 91 refers to the treatment of textile materials with solutions of water-soluble unsaturated products obtained by reacting an alkaline substance with a product manufactured from natural rubber &c. with an inorganic oxygen-containing acid or the anhydride thereof, the acid-forming element of which acid or anhydride is not in its highest valency state, and subsequent exposure to the action of an inorganic acid or the anhydride thereof, of which, if the acid-forming element may occur in several valencies, the highest is excluded.  Suitable additional compounds are phosphorus trioxide, nitrous oxide and the corresponding acids.  For the second step in addition hydrogen sulphide, hydrochloric and hydrobromic acids may be used.  Additional catalysts are benzoyl peroxide, persulphates and the like.  This subject-matter does not appear in the Specification as accepted.

Abstract: 507,257. Substitute for peppermint oil. HARBERD, E. H. (Hittel Ges., Dr.) March 7, 1938, No. 7077. [A Specification was laid open to inspection under Sect. 91 of the Acts, Sept. 10, 1938.] [Class 91] A composition having similar flavour and smell to peppermint oil, consists of synthetic menthol, menthone, menthyl acetate, and mehthyl isovalerianate. In an example, 50 per cent of menthol, 35 of menthone, 12 of menthyl acetate, and 3 of menthyl isovalerianate, are mixed together to form an oil of refreshing and cooling taste. There may be added 3-5 per cent of the initial and final distillate fractions obtained from commercial peppermint oil, eucalyptus oil, mint oil, and other similar oils which improve the flavour. These fractions contain terpenes, sesquiterpenes, terpene alcohols, ketones, polysulphides for example, d-limonene, menthene, carvo-menthene, cineol, piperitone, carvacrol, carvo-menthol, thymol, aromatic disulphides, and dimethyl sulphide. The ingredients of the composition may be made by (1) partially hydrogenating thymol to form a mixture of menthol, and menthone, which is then treated with a restricted amount of glacial acetic acid converting part of the menthol into menthyl acetate. The mixture is then distilled to obtain fractions rich in menthone, and menthyl acetate. (2) Hydrogenating piperitone in the presence of nickel to form menthone and some isomenthone which is allowed to remain in the composition. A part of this mixture is removed, and the remainder further hydrogenated and heated at 180‹ C. to form menthol, as described in Specification 238,314, [Class 1 (i)]. Part of the menthol is heated with acetic anhydride and isovalerianic acid to form the ester. The products obtained are then mixed, together with the initial distillate from Japanese peppermint oil.

Abstract: 1,246,872. Fluid-pressure brake control. AISIN SEIKI CO. Ltd. 10 Feb., 1969 [10 Feb., 1968], No. 7131/69. Heading F2F. In an anti-skid mechanism, supply of hydraulic fluid to the brakes is interrupted on sensing of an impending skid and hydraulic pressure to the brakes is subsequently reduced. Fig. 1 shows the construction of a brake pressure modulator, connected between a master cylinder 15 and the rear wheel brakes W 1 , W<SP>1</SP> 1  in its normal off condition, with chambers 52, 53 on opposite sides of a diaphragm assembly 14 both connected to vacuum. On application of the brakes, hydraulic fluid is conveyed to the rear brakes via ball valve 23, chamber 48, passage 12b and piping 19. Upon detection of an impending skid, a skid sensor 32 actuates a valve 33 to connected chamber 53 to atmosphere to cause a diaphragm 41 and thus actuator rod 21 to the left and close the ball valve 23. The whole diaphragm assembly, including member 42, diaphragm 40, diaphragm 41, and member 27, is, after a delay, forced to the left, against the action of a spring 28, thus causing a plunger 18 to move to the left and reduce the hydraulic pressure to the brakes. The valve 33 may be a solenoid operated valve, Figs. 5-7 (not shown), and a modulator may also be associated between the master cylinder 15 and the front wheel brakes Wf, Wf<SP>1</SP>. The sensor 32 may be of the type described in Specifications 935,830, 962,933 which are referred to.
