Title: Improvements in or relating to the polymerization in aqueous dispersion of polymerizable organic compounds
IPC: C08F291/00
Filed: 1946-09-05
Abstract: One or more organic compounds containing a single CH2=C< grouping are polymerized in aqueous dispersion to produce particles of predetermined size by a process comprising providing in the dispersion a known number of polymer particles of the same compound(s) or of a different polymer compatible with the polymer to be produced and of known dimensions, and maintaining present during polymerization 20-60 per cent of the theoretical amount of dispersing agent necessary to form a unimolar layer on these particles.  A substantial proportion of a previously prepared aqueous dispersion containing the polymer particles may be added to the monomer dispersion before polymerization occurs.  Preferably the ratio of monomer to polymer present in the reaction mixture is always less than two to one during the course of polymerization.  Preferred polymerizable compounds are vinyl and vinylidene chlorides and mixtures thereof with each other and with lesser proportions of vinyl esters and esters of acrylic and substituted acrylic acids.  Other polymerizable compounds listed are styrene, p-chlorostyrene, esters of acrylic and substituted acrylic acids, acrylo- and methacrylo-nitriles, acrylamide, vinyl esters, ethers and ketones, ethylene, isobutylene and N-vinyl pyrrole, carbazole, indole and succinamide and mixtures thereof.  In carrying out the process the average diameter of the polymer particles initially present is determined, e.g. by X-ray or electron diffraction methods, and the weight of polymer present also determined.  The calculation of the amount of dispersing agent theoretically required is described and 20-68 per cent of this value added to the dispersion.  Polymerization is carried out, additional dispersing agent being added during the reaction to maintain its concentration within the required range. Specified dispersing agents are stearates, oleates, palmitates, myristates, rosin, dehydrogenated rosin soaps, hymolal sulphates, alkaryl sulphonates, dialkyl succinamates and sodium N-octadecyl-N-1.2-dicarboxyethyl sulphosuccinamate.  Preferably the monomer is introduced gradually during the reaction. Polymerization catalysts may be used, e.g. benzoyl, caprylyl and hydrogen peroxides, potassium ferricyanide, sodium perborate, percarbonates, persulphates and mixtures thereof.  The hydrogen ion concentration may be controlled by addition of ammonium hydroxide or sodium hydroxide, bicarbonate or acid phosphate or of lead acetate.

Title: Regulation device for internal combustion engines
IPC: F02D9/00
Filed: 1924-11-10
Abstract: 236,796. Rogers, F. H., (Senkra Motoren- Ges.). Nov. 10, 1924. No Patent granted (Sealing fee not paid). Regulating by changing from fourstroke to two-stroke working. The engine is provided with inlet valve 3, exhaust valve 2, transfer passages 5, inlet pipe 11 from carburettor, and air-inlet pipe 23 leading to crank case. For four-stroke working, the cam shaft 16 is adjusted so that the valves 2, 3 work in the usual sequence, and a flap valve 25 connecting the pipes 11 and 23 is closed. On the suction stroke, mixture first enters through the valve 3, and afterwards air is transferred from the crank case through the passages 5. The exhaust valve is timed to open sufficiently early on the firing stroke to allow the cylinder pressure to fall to that in the crank case before the transfer passages 5 are uncovered to admit air for scavenging. For two-stroke working, the flap 25 is opened, and the cam shaft is moved axiallv so that the inlet valve is put out of action and the exhaust valve is opened by another cam at everv revolution. Mixture from the pipe 11 and air from the pipe 23 are together drawn into the crank case. Further regulation during fourstroke working is obtained by throttles 10 and 12 provided in the pipes 23 and 11 respectively. A valve actuated from the cam shaft may be provided in the pipe 23 to admit scavening-air to the crank case when the throttle 10 is closed.
