Title: Improvements in or relating to carburettors for internal combustion engines
IPC: F02M7/26
Filed: 1924-04-17
Abstract: 234,600. Brown, C., and Brown & Barlow, Ltd. April 17, 1924. Spray carburettors.-The carburettor is of the type in which the fuel nozzle is located in an air passage forming a branch of the main air passage and the invention consists in controlling a supply of air to the branch passage by a member actuated independently of the throttle valve except that as the throttle is brought to its closing position, the member is simultaneously moved to close the air supply. A piston valve c is moved across a straight-through passage having an inlet a and outlet b and carries a needle valve h for controlling a nozzle d located in a passage f whichcommunicates through a sheet of gauze g with the main passage. The passage f is in communication through holes i with an annular passage j to which air is admitted through holes in the wall of a cylinder l containing a control piston. A further supply of air is admitted to the chamber f through a duct e<1> at a point in advance of the controlled supply. The throttle valve is actuated by lever r and link s and the air-regulating piston by lever p and link o. These levers have lugs r<1>, p<1> so arranged that the throttle can be moved independently of the air-control piston, except that as the throttle approaches its closing position, the lug r<1> engages lug p<1> and closes the air supply. A pilot nozzle t may be provided, fed with fuel from the main fuel passage and with air through a controlled transverse passage.

Title: Process for coagulating and coalescing to form shaped articles
IPC: D01F6/18
Filed: 1965-03-08
Abstract: 1,092,504. Acrylonitrile polymer filaments. ROHM & HAAS CO. March 8,1965 [March 12, 1964], No. 9748/65. Heading B5B. A continuous'shaped article, e.g. a filament or film, is made from an aqueous dispersion of a polymer containing at least 50% by weight acrylonitrile (and preferably at least 85%) and which is in the form of discrete particles dispersed by means of an acid-sensitive dispersant which loses its dispersing capacity in an acidic medium, by extruding the aqueous dispersion into an aqueous acidic bath at 70-90‹ C. and containing a rapidly-diffusing acid and a solvating agent for the polymer so as to form a shaped, partly-coalesced article and then contacting said partly coalesced article with an aqueous coalescing solution for the polymer for sufficient time to provide a shaped article coalesced sufficiently for subsequent drawing. A " rapidly diffusing acid " is defined as either nitric acid of 40 to 45% by weight concentration or hydrochloric acid of 10 to 37% by weight concentration. The solvating agent is defined as either nitric acid of 40 to 45% by weight concentration (i.e. the nitric acid also functions as solvating agent), or, where hydrochloric acid is used as the rapidly-diffusing acid, or any of:-20 to 50% by weight sulphuric acid, water-soluble thiocyanates, iodides, bromides and chlorides of Group I and II metals of atomic numbers 3 to 48, or compatible mixtures of these salts. Preferably the polymer particles are less than about 1 micron in size, and the polymer dispersion is prepared by emulsion polymerization using an acid-sensitive emulsifying agent. The aqueous coalescing bath may contain any of the solvating agents used in the coagulating bath but at higher concentrations, e.g. 50 to 60% by weight nitric acid, where the aqueous acidic bath is 40 to 45% by weight nitric acid and the solvating agent used must be compatible with the components of the coagulating bath. Where a solvating acid, e.g. 55-60% by weight nitric acid or 70- 98% by weight sulphuric acid is used, the coalescing bath is preferably held at room temperature. Lower concentrations of the solvating agent may be used at elevated temperatures, e.g. 50-55% by weight nitric acid at 50- 60‹ C. bath temperature. Elevated temperatures are also preferred where inorganic salts are used as solvating agents in the coalescing bath. On leaving the coalescing bath the articles may be stretched, e.g. in a hot water washing bath, or, after washing, in hot water, or in steam, or in the dry state.

Title: Process for producing catalyst for polymerization of olefins
Inventor: CHANG MAIN
IPC: C08F4/642
Filed: 1989-10-27
Abstract: This invention relates to a process for preparing a supported metallocene alumoxane catalyst for use in the polymerization of olefins. The invention particularly relates to the use of silica gel containing from about 6 to about 20 per cent by weight adsorbed water as the catalyst support material. It has been found that such silica gel may be safely added to an trialkyl aluminum solution, preferably a mixed trimethylaluminum-triethylaluminum solution, to form by direct reaction with the adsorbed water content of the silica gel catalyst support material the alumoxane component of the catalyst system. An alumoxane coated silica gel is formed to which a metallocene may be added and the resulting material dryed to free flowing powder. The dry free flowing powder may then be used as a supported metallocene alumoxane catalyst complex for gas phase or liquid phase polymerization of olefins.
