Patent CA-2121628-A1 (CA)
Inventor: WANNG RD JOHAN
IPC: C25B1/26
Filed: 1994-04-19
Abstract: The invention relates to a process for electrolytic production of alkali metal chlorate where the demand of pH-adjusting chemicals is largely covered by integrated production of acid and alkali metal hydroxide. The process consists in electrolysing a partial flow of chlorate electrolyte produced, in a cell provided with a separator, for producing a catholyte containing alkali metal hydroxide and an anolyte containing hydrochloric acid. The catholyte and the anolyte are used in alkalisation and acidification in the chlorate process, thus significantly reducing the admission of impurities via externally produced chemicals.

Title: Radical (co)polymerization process of fluorinated olefinic monomers in aqueous emulsion
Inventor: ABUSLEME JULIO A
IPC: C08F2/20
Filed: 1994-05-13
Abstract: ABSTRACT     Radical  (co)polymerization process of fluorinated olefinic monomers in aqueous emulsion.     Fluorinated  olefinic  monomers,  optionally  in  association with non-fluorinated olefins, are (co)polymerized in aqueous emulsion in the presence of a hydrophilic solvent and of a fluoropolyoxyalkylene having hydrogenated end groups and/or hydrogenated repetitive units. In this way it is possible to obtain high productivities, close to those obtainable using a hydrophilic solvent and a chlorofluorocarbon.

Patent CA-2136873-A1 (CA)
Title: A cutter
Inventor: ROLFE JAMES G
IPC: A01D34/73
Filed: 1993-05-25
Abstract: In its preferred form, the present invention provides a blade assembly for a lawn mower, having a generally planar central body (1) rotationally balanced about a vertical shaft (24), with four projecting blades (6) extending radially from the periphery of the central body. The central body (1) is shaped with vanes (3) to form a fan-like structure or impeller. The structure is arranged to create a strong rotational flow, which carries air and cut material around with the assembly in use. The projecting blades (6) create an updraft in a peripheral region of the assembly, while the vanes (3) of the central structure are shaped to create a regulated, relatively light downdraft towards the centre. If the mower is provided with an outlet (25) for a catcher, the strong rotational flow overwhelms any influence of the relatively light secondary flows, and the air and clippings are carried centrifugally outward through the outlet. If the outlet is disclosed or the mower has no catching facility, the air and clippings continue to flow around with the assembly in a turbulent, shallow spiral inwards and downwards, to be discharged into the lawn under the mower as a mulch.
