Abstract: Alkoxy benzoyl peroxides are used as catalysts in aqueous emulsion polymerization of organic compounds containing a methylene group attached by a double bond to a carbon atom.  These compounds, which may be polymerized singly or in mixtures of two or more, include conjugated butadienes and substituted butadienes; styrene, vinyl naphthalene and alpha-chlorostyrene; acrylic and alpha-substituted acrylic acids, esters, nitriles and amides; vinyl chloride and bromide, vinyl acetate, propionate and butyrate, vinyl furane, methyl vinyl ketone, vinylidene chloride and methyl isopropenyl ketone. Suitable catalysts are o,o1-dimethoxybenzoyl peroxide, o,o1 - diethoxybenzoyl peroxide, p,p1-diethoxybenzoyl peroxide, o,o1- and p,p1-di-n-propoxybenzoyl peroxides, o,o1- and p,p1-diisopropoxybenzoyl peroxides, p,p1-diisobutoxybenzoyl peroxide, p,p1-di - n - hexyloxybenzoyl peroxide, p,p1 - di - n - heptyloxybenzoyl peroxide, 2,4,21,41- and 2,6,21,61 - tetramethoxybenzoyl peroxides, and mono-substituted 2-ethoxybenzoyl peroxide.  These may be used alone, with each other or with other catalysts.  The usual buffers and emulsifying agents may be present in the emulsion, and polymerization is preferably carried out in an inert atmosphere at a temperature of 40-50 DEG  C.ALSO:As an example of the preparation of alkoxy-benzoyl peroxides, used as polymerization catalysts (see Group IV (a)), o,o1-diethoxy-benzoyl peroxide is prepared by reacting o-ethoxy-benzoyl chloride with sodium peroxide, the product being a white crystalline solid.

Title: Manufacture of basic calcium chlorate
IPC: C01B11/14
Filed: 1945-11-15
Abstract: Basic calcium chlorate Ca(ClO3)2.Ca(OH)2 for herbicidal use is precipitated by introducing 1 to 1.1. mols. of hydrated lime per mol. of calcium chlorate to be precipitated into a solution containing at least 50 per cent by weight of Ca(ClO3)2.  To obtain readily separable crystals lime is preferably slowly and continuously added in powder form or liquid suspension to chlorate solution between 50 DEG  C. and the boiling point.  Improved yields are obtained by gradually lowering the temperature to about 5-10 DEG  C. as precipitation proceeds. Mother liquors may be used in a cyclic process to suspend lime and dissolve further calcium chlorate.  If the lime is added at once the fine slurry produced is preferably dried by evaporation and addition of powdered quicklime.

Title: Improvements in or relating to change speed gear
IPC: F16H59/04
Filed: 1928-10-26
Abstract: 322,599. Thornycroft &. Co., Ltd., J. I., and Barford, V. G. Oct. 26, 1928. Controlling, variable-speed gearing. -In selector control gearing suitable for a motor omnibus in which a shaft 20, Fig. 6 or Fig. 3, which slides and turns is connected to a shaft 30 which turns and slides correspondingly, toothed gearing is used to connect the shafts. In the arrangement shown in Fig. 6, a drum 36 with pin teeth 37 is secured to the shaft 20. The teeth 37 constantly mesh with pitch holes 38<a> in a drum 38 fast on the shaft 30. When shaft 20 slides, drum 38 turns without changing mesh of the pin teeth. A control lever 1, Fig. 5, with a sector 33 with pin teeth 34 may similarly turn and slide a recessed drum 35 on the control end of shaft 20. A rack pinion A, Figs. 2 and 3, fast on shaft 20 may mesh with rack pinion B fast on transverse selector shaft 30. The pinion A has annular rack teeth 24 pierced for the passage of rods 26, which act as pinion teeth. The rods 26 engage between parallel wheels 32 which form the rack teeth of pinion B. The wheels 32 are formed with pinion teeth to engage with the annular teeth 24 of pinion A. When either shaft slides, the other turns, and vice versa. The shaft 30 is preferably hollow, supported on end pins 31 and biased to a mid position by springs 30a, 30b. It carries a pinion 29 adapted to be slid to engage toothed rods 28 alternatively, and then be returned to operate the rod selected. The rods 28 are interlocked by a set of three pins 28d which are sometimes in line. The pinion 29 has a notch co-operating with stops 29b, 29<c>, Fig. 2, to ensure that a change can take place only when control lever 1, Fig. 1, is in neutral. The lever 1 is connected to the shaft 20 by a toothed sector 3 on the lever engaging a toothed pinion 4 on the rod between cheeks 8, 9 which effect the sliding of the rod when the lever is moved in the plane of Fig. 1. The lever 1 is supported on a ball pivot 10 pressed upwards by a spring 18 and carries a reverse stop in the form of a disc 17 held in the plane of a fixed stop bar 19 by a spring 12. When reversed driving is wanted, a knob 15 is raised against spring 12 to lift disc 17 clear of bar 19, after which a turning of shaft 20 is effected through the gearing 3, 4. A modification is described in which the elements 3, 4, 8, 9 are replaced by a ball on the lower end of lever 1 engaging the socketed end of a short lever fast on shaft 20.
