IPC: A61M5/142
Filed: 1994-08-08
Abstract: A liquid dispensing device (2) and a method of dispensing liquid are disclosed The device (2) includes a hollow gas and liquid tight casing (4), a flexible gas and liquid tight membrane (18, 130) having at least one convolution(132) and disposed across the casing interior and dividing the interior into a propellant chamber (36) and a liquid chamber (24), an outlet port (28) from the liquid chamber (24), two mutually reactive chemicals (38. 40) in the propellant chamber (36) but reactive upon contact to form a propellant gas. Upon generation of the gas, the gas expands against the membrane (18, 130), pressurizing the liquid chamber (24) to expel the contained liquid through the outlet port (28). A pressure relief valve (45), suitable for use with the device, allows gas to escape from the device when the gas pressure exceeds a predetermined level.

Patent CA-2171868-A1 (CA)
Title: Method for dosing therapeutic compounds
Inventor: ALEXANDER PETR
IPC: A61P31/12
Filed: 1994-09-16
Abstract: The internally cyclized congeners of hydroxy-substituted nucleotide analogues have been found to exhibit substantially lower toxicity in vivo than their uncyclized analogues, while retaining essentially the same antiviral activity. This was unexpected because the prior art would have suggested that the cyclic analogues offered no significant advantages in respect to toxicity in vivo. This finding permits the administration of much greater doses of the cyclic congeners than otherwise would have been possible and/or allows the clinician to omit toxicity ameliorating interventions. Novel compounds are provided for use in the method of this invention. Novel methods for the preparation of these compounds also are provided.

Title: Composition and improved ph driven method for wastewater separation using an amphoteric carboxylate and a cationic destabilizer composition
Inventor: FALBAUM DAVID J
IPC: C09K23/18
Filed: 1995-06-08
Abstract: Improved separation of emulsified hydrophobic organic soils can be obtained from aqueous effluents using an amphoteric carboxylate surfactant material in combination with cationic destabilizer or flocculent materials.  Such a treatment in combination with an acidic pH adjustment causes the rapid separation of hydrophobic organic soils from the aqueous stream.  The treated aqueous stream is environmentally compatible. Improved laundry detergents comprising an organic amphoteric carboxylate surfactant and selected nonionic surfactants provide both cleaning for fiber and fabric containing items soiled with substantial quantities of hydrophobic soil.  The pH of an effluent generated in such cleaning processes can be adjusted to an acid pH and treated with a cationic material causing a break that permits rapid and substantially complete separation of the hydrophobic organic soils from the effluent.  Residual concentrations of organic soil in effluent water can be less than 250 ppm and can be as low as 100 ppm.

Title: Automated tube reforming apparatus and associated methods of manufacturing
Inventor: STACHOWIAK ROBERT S
IPC: B29C57/00
Filed: 1996-10-10
Abstract: A tube reforming apparatus and associated methods provide efficient mass production of reformed tube end portions.  In a preferred embodiment,  a tube reforming apparatus has a loading station, two heating stations, a forming station, and an unloading station.   The  loading station permits rapid loading of a series of laterally spaced apart tubes into clamping fixtures, and accurately meters a downwardly extending end portion of each tube.  The heating stations permit accurate and evenly distributed heat to be applied to the end portions to make them pliable.   The forming station reforms the end portions between a mating die pair, while compensating for any volume variation in the end portions.  The unloading station automatically unloads the tubes from the clamping fixtures. Automation features of the apparatus permit these operations to be efficiently accomplished.

Patent CA-2195870-A1 (CA)
Title: Method and apparatus for screening a fiber suspension
Inventor: AALTONEN FRANK
IPC: D21D5/16
Filed: 1995-07-28
Abstract: The differences in performance of a screening cylinder during screening of a fiber suspension (e.g. low consistency paper pulp) at the inlet end compared to the reject end is accommodated by constructing the feed side surface of the screening cylinder so that it induces greater turbulence in the vicinity of the screen cylinder surface adjacent the reject end of the screen than adjacent the inlet end. Typically this increase in turbulence is at least about 10 % (preferably at least about 40 %, and typically greater than 100 %).  The turbulence increase can be provided by a substantially smooth screening medium surface at the inlet end and a contoured screening medium surface adjacent the reject end, or by first and second contoured surfaces of different aggressiveness. Contoured surfaces typically include grooves, and variables that may be changed to affect the turbulence, include the depth of the grooves, the angle of inclination of the downstream wall of the grooves, the spacing between the grooves, the radius of curvature of the opening (holes or slots) edges, the frequency of openings in grooves, and the dimensions of the openings (holes or slots) in the grooves. The screen cylinder is mounted in a pressure screen housing.
