Title: Process for the treatment of polymers of alpha-olefins
IPC: B25B13/46
Filed: 1958-03-25
Abstract: A process for the preparation of solid polyolefin products from polyolefins containing catalyst residues remaining after polymerising olefins having a terminal olefinic double bond and containing 2 to 8 carbon atoms in the presence of a catalyst comprising a halide of titanium, zirconium, hafnium, vanadium, niobium, chromium, molybdenum or tungsten and an activator therefor comprising a metal alkyl, a metal hydride, a metal borohydride or an alkyl metal halide, comprises contacting said polyolefins containing catalyst residues comprising inorganic metal components with aqueous solutions of alkali metal bicarbonates or oxalic acid and separating the polymer from the aqueous solution, provided that when an aqueous solution of oxalic acid is used the concentration and quantity of said solution are sufficient to supply at least 1,5 mols of oxalic acid per mol of metallic components listed above of metals of Group IV(A) to VI(A) of the Periodic Table of Mendeleef.  After polymerisation the catalysts may be deactivated by adding water, methanol, ethanol, propanols or butanols prior to treatment in accordance with the invention. Alternatively the aqueous bicarbonate or oxalic acid solution may be used to deactivate the catalyst and remove the residues thereof. When contacting is effected at temperatures below 50 DEG C. the oxalic acid solution may contain up to 5% of nitric acid.  The polymers may be ethylene, propylene, butene-1, isobutylene, 3-methyl butene-1, 3-methyl pentene-1 or butadiene polymers.  Examples describe the polymerisation of propylene in the presence of titanium trichloride, aluminium triethyl and n-heptane and the treatment of the product with (1) potassium and sodium bicarbonate solutions, (2) isopropanol and sodium bicarbonate solution, (3) isopropanol and oxalic acid solution and (4) oxalic acid solution containing nitric acid.  The products are compared with those obtained by treating with aqueous potassium carbonate solution and with a solution of nitric acid in isopropanol.

Title: Improvements in the construction and method of working internal combustion engines
IPC: F02M1/00
Filed: 1924-04-17
Abstract: 239,896. Le Mesurier, H. E. April 17, 1924. Stop-gear. - In an internal - combustion engine in which loss of heat from the cylinder is prevented by supplying water from a tank to a nozzle in the inlet pipe, in the carburettor, or in the transfer passage in the case of a two-stroke engine, means are provided for stopping the engine in case of failure of the water supply. In one form, a float in the tank is provided with a contact arm which short-circuits the ignition magneto when the tank is empty. In ignitiontube gas engines, or in oil engines, the float is arranged to turn off a gas or oil supply cock 24. The float may comprise two open-ended cylinders 21, 22, with the open ends facing each other, so that upward movement of the float is ensured by air trapped in the part 22 and downward movement by water retained in the part 21. The float is enclosed in a cylinder attached to a removable plate, to prevent its being affected by surging of the water. In an alternative form, the float is connected through a lever to a valve adapted to close an air vent in an otherwise airtight petrol tank, in order to cut off the petrol supply to the engine. In a further form, the float is rigidly connected to an outlet valve in the petrol tank for the same purpose. In order to stop the engine if the water nozzle becomes choked, the resulting increase of temperature in the cylinder may cause the expansion of a medium in a tube to move a plunger and cut off the petrol supply. Reference has been directed by the Comptroller to Specifications 5147/97, [Class 7, Air and gas engines], and 14591/03.

Abstract: PURPOSE:To obtain a color image of high image keeping down the unevenness of color tone from mixing of colors to the minimum by making a developing device of a multi color processing unit individually exchangeable and at the same time, restricting the specified developing device to be attached to a specified position. CONSTITUTION:The multi color processing unit 3 is fitted onto a main body attachably/detachably, and the developing units 36 to 38 of the unit 3 are easily attachable/detachable with an attaching mechanism. The developing devices 36 to 38 are set and stacked in the vertical direction, according to the type of developer, and attached and restricted by a key shaped projection and a key groove to the specified position. That is, the developing device 36 containing the yellow developer, which is most affected by mixture of colors, is attached to the uppermost position, and the cyan developing device 38, which receives little effect, is placed in a lower position, with especially black color developing device always attached in the lowermost position. Thus, unevenness of the color tone due to mixture of developer can be kept down to the minimum, and an image forming device which can form the color image of high quality can be obtained.
