Title: Improvements in or relating to electrophotography
IPC: G03G17/02
Filed: 1962-04-19
Abstract: For developing a visible record on a photoconductive layer which has been or is being exposed to a light image, D.C. is passed through a dilute aqueous solution containing silver, calcium and acetate ions in contact with an anode and the surface of the photoconductive layer which is carried by, or whose other side is in contact with a conducting layer serving as a cathode. Typically the applied voltage is from 30 to 80 volts, the solution contains also a silver complexing agent such as a 2-hydroxyethylaminooligoethylene sulphide as in Specification 1,007,582, the silver ion is introduced as silver nitrate and the calcium and acetate ions as calcium acetate, while the photoconductive layer is ZnO in a butadienestyrene resin carried on an aluminium support. An A.C. source may be used due to the rectifying action of the electrolyte-photoconductive layer interface. Comparison tests are made using, instead of calcium acetate, magnesium acetate, chlorides or nitrates of calcium magnesium, or barium, or strontium nitrate.

[Classes 2 (iii) and 15 (ii)] [Also in Group VIII] Quaternary ammonium compounds are obtained by reacting tertiary aliphatic or heterocyclic amines with compounds having the formula wherein X is hydrogen, alkyl or aralkyl, Y is O or COO and Z is halogen. In examples, pyridine is reacted with the chlormethyl derivatives of 5-octadecyloxymethyl-2-hydroxybenzoic acid, 2-octadecyloxymethyl-4-chlorphenol and 4-octadecyloxymethylanisol. The ether and ester starting materials are prepared from the corresponding chlormethyl derivatives and compounds having the formula HYC 15/18  H 31/37 . The resulting intermediates are then heated with formaldehyde and hydrogenhalide. Tertiary amines mentioned are quinoline, monoalkylpiperidines and trimethylamine. The products, which form froths in aqueous solution are used for rendering textiles water repellent, by treating the latter with aqueous solutions of the products and heating. A sample has been furnished under Sect. 2 (5) which is prepared by treating trimethylamine with the chlormethyl derivative of an ester obtained by condensing sodium stearate with 5-chlormethyl-2-hydroxybenzoic acid. The Specification as open to inspection under Sect. 91 comprises also the treatment with tertiary amines of phenols and ethers having the above formula in which Y is a bivalent residue such as NH, NHCO and NHCONH, and additional examples use chlormethyl derivatives containing a carboxyamide residue. This subject-matter does not appear in the Specification as accepted.

[Class 44] A safety lock, particularly for bicycles in that it can be mounted on a bicycle frame by means of a plate 2 secured removably by a dove-tail connection to one of its sides, comprises a fixed casing I in which is slidably mounted a bolt 3, having a solid cylindrical rod 31 intended to engage in a recess in a locking device on the wheel, and a hollow cylindrical part 4 provided with a hollow longitudinal rib 5, which has a small side projection 6 guided in a slide .7 in the casing and acted upon by a spiral spring 8 which tends to keep the lock in the released position ; a revolving barrel lock controlled by sectioned, spring- urged pin-tumblers is mounted in the hollow part 4 of the bolt, the barrel 9 having a radial pin 16 the head of which co-operates with a radial slit 17 in the part 4 of the bolt and engages in a U-shaped slide 18 in the wall of the casing 1 to which the plate 2 is secured. Thus by introducing the correct key into the passage 10 in the barrel when the lock is released and by giving it a quarter turn, the bolt can be pushed from right to left, (Fig. 4), the head of the pin 16 now lying at the left hand side of the transverse branch of the slide 18 ; the key is now given a quarter turn in the opposite direction, so that the head of the pin 16 lies at the top of the left-hand side arm of the slide 18, in which position the bolt is locked and the key can be removed. For unlocking, the key is inserted in the same angular position as for locking, and given a quarter turn ; the bolt is then released under the action of the spring 8. The right angle 18<1> of the slide 18 is rounded to facilitate the return of the bolt into the unlocked position. The slide 18 may be of a more complicated shape, involving more than two rotations of the key and one axial displacement of the bolt for operation.

Title: Improvements in or relating to the cleaning of rags by solvents

Filed: 1929-05-17
Abstract: 312,319. Rozieres, J. A. L., and Soc. Anon. des Produits OlÚiques. May 24, 1928, [Convention date]. Fats and fatty oils, extracting by solvents.- In an apparatus for degreasing rags by a volatile solvent in which the extractor is connected with a series of vessels holding solvent containing fat in increasing concentrations, the fat-laden solvent in the last vessel is passed by gravity to a still, and the condensed solvent is returned to the first vessel which supplies pure. solvent to the said vessels to decrease the concentration of fat contained therein. In a suitable apparatus the rags are agitated in a vessel 3 and are treated with a solvent, containing some dissolved fat supplied from a vessel 7 through a pipe 3<1>. The solvent containing the fat then passes to a centrifuge 4 and after water and solid particles are removed, returns to the vessel 1 through the pipe 9. When extraction is complete the rags are rinsed with substantially pure solvent fed through the pipe 3<1> from the vessel 2. During this treatment a cock 16 is opened, allowing pure solvent to pass from vessel 2 to replace a portion of the fat-laden solvent in vessel 1 and the latter liquid passes by gravity through a pipe 13 to a steam-heated still 5, where the solvent is volatilized and passes through pipe 14, and condenser 6 to the vessel 2. After rinsing the rags are treated with steam fed through pipe 11 to remove the contained solvent which is vaporized and passes through pipe 12 and the condenser 6 to the vessel 2. The residue of fat in the still 5 is treated with steam to vaporize contained solvent, and is run out by the cock 17.

Title: A process of preparing organopolysiloxane compositions
IPC: C08G77/00
Filed: 1955-05-31
Abstract: In making an organopolysiloxane by hydrolysing one or more silanes of the general formula RnSiX4-n, wherein each R is a monovalent hydrocarbon or halogenated hydrocarbon radical, X is a hydrolysable radical and n has a value from 1 to 2, the hydrolysis is effected in the presence of styrene in amount such that the hydrolysis product is in solution therein, and the styrene solution is thereafter separated from the aqueous phase and any hydrolysis by-products.  The term styrene includes styrene, a -methylstyrene, chlorostyrene, bromostyrene, vinyltoluene, divinylbenzene and mixtures thereof, and the amount used may range from 1 to 99 per cent by weight of the finished product.  Silanes specified are dimethyldichloro-, vinylphenyldiethoxy-, diphenyldiacetoxy-, octadecyltri-, chloro-, cyclohexyldichloro -, methyldichloro -, chlorophenylmethyldichloro -, trifluoromethyl - phenyltrifluoro -, bromoxenyltrichloro - and tolylmethyldichloro-silanes and phenylmethylsilazanes; and these may be used with unsubstituted silanes, e.g. silicon tetrachloride, ethyl silicate or trichlorosilane, or with R3SiX silanes.  The hydrolysis may be effected by adding the silane(s) to a mixture of styrene and water, and preferably a polymerization inhibitor, e.g. tertiary butyl catechol, and carrying out the hydrolysis at temperatures below the reflux temperature of the styrene.  Alternatively, the water may be added to a styrene solution of the silane(s).  If desired minor amounts of other solvents, e.g. ethanol, may be added.  In examples, siloxane solutions are made in the above manner from (1) methyltrichloro-, phenyltrichloro-, dimethyldichloro- and diphenyl-dichlorosilanes; (2) butyltrichlorosilane; (3) dimethyldichloro-, phenyltrichloro- and methyltrichloro-silanes; (4) dimethyldichloro,- chlorophenyltrichloro- and vinyltrichloro-silanes. The solution from (1) was added to a maleic anhydride polyester resin in amounts varying from 1 to 50 per cent by weight of polysiloxane calculated on the total composition, and cured; The solution from (2) was added to styrene monomer or a partial polymerisate thereof and then polymerized. The compositions may be incorporated in any compatible organic resin, whether synthetic or natural.
