Title: Improvements in or relating to the electrolysis of alkali chlorides
IPC: C25B1/36
Filed: 1941-02-10
Abstract: 541,292. Electrolysis of alkali chlorides. TAYLOR, M. C., and GARDINER, W. C. Feb. 10, 1941, No. 1799. [Class 41] In the electrolysis of alkali metal brines to produce chlorine and alkali hydroxide, employing a mercury cathode, the composition of the circulating brine is controlled to contain in grains per litre calcium not exceeding about 3.6, iron not exceeding about 0.0001, and magnesium not exceeding about 0.006. The brine discharged from the cell or a portion of it is de-chlorinated by reduction of the pressure or the passage of inert gas such as air or nitrogen, which has the effect of precipitating the iron in the form of hydrated oxides. Magnesium is precipitated as hydroxide by rendering the de-chlorinated brine alkaline (pH 9.4 to 10.4) by the addition of alkali hydroxide. The filtered brine is re-saturated with alkali metal chloride before returning to the cell. If it is desired to remove hypochlorous acid and sodium chlorate produced during the electrolysis, this is done by adding hydrochloric acid during the de-chlorination step.

Abstract: 953,835. Tyre chafers. WEST POINT MANUFACTURING CO. Jan. 16, 1963 [Feb. 1, 1962; Nov. 9, 1962], No. 1929/63. Heading B7C. [Also in Division D1] A non-woven fabric for use as a tyre chafer material is made by prebonding a multidirectional fibre web with a minor quantity of elastomeric material, drying the web to cure the prebond material, rebonding the web with a major quantity of elastomeric material and drying the web without substantial curing of the rebond material. An airlaid or cross-laid-carded fibrous web 10 of cotton, viscose rayon, polyamide, polyester or poly acrylic fibres or a mixture thereof is passed through a prebonding bath 14 of elastomeric material to lightly bind the web 10. Excess liquid is removed by a suction box 16. The web 10 passes through a heater 18 to dry the web and substantially completely cure the prebond material. The prebond material preferably contains both vinyl pyridine-butadienestyrene terpolymer latex and butadiene-styrene latex with resin-forming ingredients, such as resorcinal and formaldehyde, and with caustic soda added. Other elastomers, such as natural, butyl and nitrile rubber, may be used in the prebonding composition either alone or with other elastomer and/or resin. Specified elastomers are nitrile rubber latex, medium nitrile butadiene-acrylonitrile rubber latex, medium nitrile carboxylate butadiene acrylonitrile rubber latex, aldehyde resins such as a triazine type thermosetting aldehyde resin precondensate, a methylated methylol melamine resin and diammonium phosphate as a catal ys for resin cure. The web 10 may then be needled by a needle loom 20, the needleholes serving as pores to facilitate entry of additional bonding material. The web 10 then passes through a re-bond bath 28 in which it is thoroughly impregnated, excess binder being removed by a suction box 30 and the web then being dried by a heater 32. The elastomeric rebond material is non-curable and contains no vulcanising agent, accelerator or catalyst. The rebonding material preferably contains both natural rubber latex and butadiene-styrene rubber latex with a styrenated phenol type antioxidant and a potassium rosin stabilizer. Fillers, such as carbon black or clay, may be added to the rebond material. The fabric then passes through rebonding baths 38, over suction boxes 40, 44 to remove excess liquid and over dry cans 42, 46. Also additional binder may be applied by dip and squeeze padders. Each bath 38 may be identical in composition with the bath 28 or may additionally contain glyceryl ester of rosin, carbon black pigment, zinc oxide, sulphur, zinc mercaptobenzothiazole and diphenyl guanidine. Examples of fibre denier, fabric density at each stage of the bonding, drying temperatures and the percentage compositions by weight of the binders are given in the Specification. Specification 703,574 is referred to.

Abstract: 1396619 Toy aeroplanes &c MATTEL Inc 17 Jan 1973 [7 Aug 1972] 2384/73 Heading A6S [Also in Division F2] A powered, propeller driven toy, shown as an aeroplane, has an impact resistant, energy absorbing device associated with the propeller, viz. in the drive to the propellor or in the connection between the propeller mounting and the toy body, to protect the toy if it strikes an obstruction. In one form, a driving gear 149, Fig. 3, is connected to a frusto-conical torque transmitting resilient coupling 159 of rubber or neoprene in turn friction fitted to the end of a propeller shaft 35. A removable, shock-absorbing propeller shaft housing 181 surrounds and journals the propeller shaft, a portion 191 of the housing acting somewhat in the manner of a Belleville spring to allow relative rearward movement of the propeller shaft if the propeller strikes an obstruction, Fig. 5 (not shown). At the same time the resilient coupling 159 tends to collapse, and allows the propeller shaft to move axially towards the gear 149. Projections 163 on the coupling 159 extend through holes in the gear 149 to hold the parts together. An electric motor 83, Fig. 1, controlled by an on-off switch 111, has its drive pinion 143 meshing the gear 149. In the "off" position of the switch 111, a jack plug can be inserted through a hole 121 to recharge batteries 93 powering the motor. The shock absorbing propeller shaft housing 181, Fig. 2, has radial tabs 205 latched by twisting under tabs 201 in a transverse wall plate 31 inserted behind lugs 43 in a frame of the aeroplane fuselage 15, and retained by a catch 55. The motor 83, &c lies behind the wall plate 31. In the form shown, the front 187 of the propeller shaft housing 181 is tubular, and fins 189 are formed at its end around the propeller shaft journal. In a modification, Figs. 6, 7 (not shown), the front of the propeller shaft housing is tapered, and is formed with axial ribs (213). In a further modification, a coupling 373, Figs. 8, 10, connecting the propeller shaft 319 to its drive shaft 333, consists of a tube 385 with axial slots 383 receiving the T-shaped end 387 of the propeller shaft to allow its inward movement. A resilient, energy absorbing propeller shaft support 345 has broad, flat sides, Fig. 8, which are bowed, Fig. 10, if the propeller is pushed back on impact. In yet another modification, a similar coupling contains a spring 381, Fig. 11, abutting the T- shaped propeller shaft end 387, and universal movement is allowed by a ball 333A on the shaft end 333 having radial pins 333B engaging axial slots in the coupling sleeve. A resilient energy absorbing noze cone 403, which supports the propeller shaft, collapses on impact, Fig. 12 (not shown).
