Patent CA-2187589-A1 (CA)
Title: Sheet-fed printing machine
Inventor: SCHAEDE JOHANNES GEORG
IPC: B41F15/20
Filed: 1996-10-10
Abstract: The impression cylinder (2), which together with the cylinder (1) that prints the image, forms the printing nip, co-operates with two transfer cylinders (3, 4) which feed or remove the sheets, and has an essentially closed cylindrical circumferential surface, into which, at the beginning of each impression segment, a suction strip (5, 6) is inset to apply suction to the front edge of a sheet.  The two transfer cylinders (3, 4) are similarly provided with suction strips (7, 8;  13, 14) which are arranged in good register with the suction strips (5, 6) of the impression cylinder (2), and moreover have dipping grippers (10, 12; 16, 18), which are located in gaps in the dipping strips. Sheet transfer to and from the impression cylinder (2) is effected by alternately switching on and off the suction air at the relevant suction strips. As they pass the printing nip, the dipping grippers of the transfer cylinders occupy their lowered position, whilst away from the printing nip, they occupy their raised position, in order to hold the sheets while the suction air of the relevant suction strip is switched off.

IPC: B62C5/02
Filed: 1996-11-01
Abstract: The invention pertains to a compositely constructed sulky shaft for use with sulky bikes in harness racing. The shaft comprises wood and reinforcing material laminated to parts of the shaft, the reinforcing materials allowing for a dimensionally smaller shaft in cross section but yet a strong shaft while providing a significantly lighter shaft than wood-only shafts of the prior art. The composite shaft has a tip portion, a receiver end portion, a vertical bend portion adjacent the tip portion and an elongate portion intermediate the vertical bend portion and receiver end portion. Preferably, reinforcing material is laminated to both sides of the receiver end portion and the intermediate portion but short of the vertical bend portion. The tip portion preferably has a reinforcing material insert layer laminated into a slit or split in the wood of the tip portion, the layer running perpendicular to the sides of the tip portion. The split and associated laminate insert to the tip portion preferably extends inwardly to the vertical bend portion of the shaft but short of the point where the reinforcing material laminated on the sides of the intermediate portion of the shaft stops.

Patent CA-2195039-A1 (CA)
Inventor: ZHANG JIHAI
IPC: H04B1/40
Filed: 1997-01-14
Abstract: A frequency stabilized communication system comprising Doppler -shift detective and corrective unit  and  dual-carrier  radio receiver is employed to  decrease  a  Doppler  frequency-shift effect due to relative movement between  mobile  station  and base one, drifts of local oscillation signals of receivers and transmitters. The dual-carrier receiver completes the frequency selection and frequency conversion with utilizing  mixture  of local oscillation signal of receiver and  dual-carrier  signal itself so that effect to frequency-drift is reduced, and power consumption of local oscillation generator is  controlled. Due to applying the Doppler-shift detective and  corrective  unit, the frequency of reception and transmission of mobile  station will be remotely real-time controlled by base  station  or  be by mobile one itself directly as the movement  state  of  that changes, which avoid the adjacent channel interference from the transmission of mobile station against the  receiver  of  base one and balance from the receiver of mobile one against signal.

Title: Sewer inspection chamber with back-flow prevention valve and method and apparatus for installing valve in sewer inspection chamber
Inventor: WATTS LEON B
IPC: F16K15/03
Filed: 1997-04-09
Abstract: An inspection chamber for use in sanitary sewer systems has an integral back-flow prevention valve. The valve can be installed through an access pipe with the inspection chamber in place underground. The valve does not interfere with the installation or removal of a plug in the inspection chamber during construction and inspection of the sewer system.

Title: Co-production of potassium sulfate, sodium sulfate and sodium chloride
Inventor: LAMPERT SHALOM
IPC: C01D3/08
Filed: 1995-11-13
Abstract: A process for producing potassium sulfate, sodium sulfate, and sodium chloride from potash and a sodium sulfate/water source, wherein potash (12), sodium sulfate (14), slurry (34) from the recovery stage and brine (18) from the gaserite decomposition stage (20) are introduced to a first stage (10), wherein the sodium sulfate and potash dissolve, such that glaserite is precipitated. The slurry is concentrated and delivered (22) to the glaserite decomposition stage (20) along with water (24). Potash is introduced directly (8) and/or via stream (22) by introducing excess potash into stage (10). The potassium sulfate solids are separated, washed and dried to give a potassium sulfate product (27). The mother liquor (18) removed from the reactor is returned to the glaserite production stage (10). The brine (26) produced in the production of glaserite (10) is evaporated in an evaporative crystallizer (28). The removal of water (30) produces a supersaturation of sodium chloride, which precipitates out of solution.

The method inhibits adsorption of container-derived substances on a drug to preclude development of insoluble particulate matter owing to said adsorption in an aqueous solution prepared extemporaneously without causing loss of the drug and avoiding the toxic effect of decomposition or degradation of the drug, thus insuring a long-term trouble-free stable shelf-life of the drug.
Patent CA-2208200-A1 (CA)
Title: Injection molding apparatus and method
Inventor: ERIKSON ERIK E
IPC: B29L22/00
Filed: 1989-11-01
Abstract: A method and apparatus for making a plastic injection molded part with a smooth surface or skin and a hollow core wherein thermoplastic material is injected as a molten stream into the mold cavity through a sprue bushing fixed in the mold.  Simultaneously, an unmeasured quantity of inert gas is introduced through an adapter into the molten stream at the sprue bushing substantially coaxially with the melt stream and at a pressure sufficient to penetrate the thermoplastic material to form a gas cavity in the molten material in the mold.  For retrofitting an existing mold, an adapter can be added to the existing sprue bushing.  During plastic injection and cooling in the mold the gas is maintained at a high pressure, preset, constant and adequate to maintain the plastic against the mold surface until it is self-supporting.  The gas is exhausted from the mold, back through the sprue bushing and adapter, before the mold is opened.  Adequate preset high pressure is maintained at the gas supply by a large cylinder having a positive displacement member therein that is controlled by a pressure sensor in the gas pressure line to the mold to maintain preset adequate gas pressure within the cavity.
