Patent CA-2088300-A1 (CA)
Title: Oil-in-water emulsions
Inventor: DAHMS GERD H
IPC: B01F23/00
Filed: 1993-01-28
Abstract: An oil-in-water emulsion containing 0.5% to 30% metallic oxides having a particle size of less than 0.2 micron, less than 10% total emulsifier, 5% to 30% of an oil phase and at least 60% of an aqueous phase is provided.    The invention also makes available a method of preparing such emulsions in which the emulsion is formed by use of a dispersion in water of the metallic oxide particles.        By comparison with previously known emulsions of this type relatively small quantities of emulsifiers are used and it is possible to use an emulsion system with a low HLB value (e.g. less than 6). Preferably no hydrophilic emulsifiers are used.        The emulsions are suitable for preparing UV-absorbing compositions such as sunscreens, moisturisers and after-sun lotions. The ability to use no, or little, hydrophilic emulsifiers is advantageous since, in, general, these emulsifiers are not biodegradable whereas hydrophobic emulsifiers generally are biodegradable.

Title: Vacuum Filtration System and Method of Filtering Pulp Fibers from Pulp Slurry Using the Same
Inventor: LEWIS FREDERICK S
IPC: D21F1/76
Filed: 1993-10-28
Abstract: A method and apparatus for filtering pulp fibers from a pulp slurry, using a combination of vacuum, hydrodynamic and hydrostatic forces in order to achieve a more effective deposition of pulp fibers onto the filter surface and enhanced flow of filtrate through the cylinder.  The apparatus is in the form of an improved vacuum filtration system, in which the filtrate outlet tube is disposed along the axis of rotation of the rotary cylinder and the filtrate inlet and outlet ports of each filtrate conduct are radially offset from one another in the direction of intended rotation of the cylinder.  During various phases of filter operation, vacuum forces generated by the vacuum source cooperate with either hydrodynamically or hydrostatically generated forces, which together act upon columns of filtrate in the filtrate conduits as the cylinder rotates.
