Patent CA-2192410-A1 (CA)
Inventor: WOOD LEONARD BRENT
IPC: B66F15/00
Filed: 1996-12-09
Abstract: A lifting device particularly suitable for snowmobiles includes a frame with ground engaging feet, a lever pivotally mounted on the frame and connected to a load engaging post which is raised upon movement of the lever from an upper to a lower position, and a latch for holding the lever in its lower position to hold the post in its raised position. A safety catch is movably mounted on the lever for movement relative to the lever between an operative position, in which it prevents release of  the  lever  from  its  latched position,  and  an inoperative position in which the lever can be moved from the lower to the upper position after release of the latch. The safety catch is movable relative to the lever under gravity and arranged  so  that  it  automatically moves  to  an  operative position when the lever is moved to its lowered position and the load is  lifted,  and when the  lever  is  in the  lower position, if the catch is moved from the operative position to the inoperative position,  the catch remains in the latter position while the latch continues to hold the lever in the lower position.

Filed: 1995-08-17
Abstract: A method based on polymerase chain reaction (PCR) amplification and oligonucleotide ligase assay (OLA) reaction is provided for analyzing complex genetic systems in a single reaction vessel. The method involves simultaneously incubating a sample containing one or more target polynucleotides with PCR primers and OLA probes in a single reaction mixture.  The presence of variant polynucleotide sequences in the sample is determined by detecting and identifying the products of the OLA reaction.

Title: Wound roll support in a web winding machine
Inventor: WOHLFAHRT MATTHIAS
IPC: B65H18/26
Filed: 1997-02-14
Abstract: A winding machine for a continuous web includes at least two support rollers defining a bed for the wound web. At least one roller has a rotatable, perforated roller shell. A stationary pressure box disposed inside the roller shell which is opened toward the inner surface of the perforated shell and is connectable to a source of pressure air. A further longitudinally extending packing closes the bottom of the gap between the first and second rollers. Longitudinal packings at the pressure box define a pressure zone extending approximately from the further packing to the place where the round roll lies on the one support roller. A suction zone is defined at the support roller upstream in the direction of roll shell rotation from the pressure zone. A grid of walls along the pressure zone in the pressure box define axially shorter length individually pressurizable zones connectable to a pressure source. In an alternate embodiment, three support rollers define two roll beds.      The first and third of the rollers are support rollers as described above.

Patent CA-2199811-A1 (CA)
Title: Animal feedstuffs and additives
Inventor: CHANDLER PETER JOHN
IPC: A23K1/00
Filed: 1995-09-15
Abstract: Feedstuffs for domesticated animals can be improved by inclusion of choline e.g. as choline chloride. Ruminants cannot benefit from choline in feed unless the choline is protected from destruction in the rumen. Improved protection against ruminal destruction is provided by supporting the choline compound, especially as an aqueous solution, on a carrier particularly ground corn cob, other similar cellulosic material, or porous hydrophilic silica, and coated with or included within a matrix of a protective fatty acid or soap having a melting point above 40 ~C. Even better results can be obtained by including alkali with the choline compound to form caps of soap over the choline compound in the pores of the carrier and/or to plasticise the fatty acid matrix.

Inventor: CHICOINE RICHARD
IPC: F41A9/83
Filed: 1997-04-04
Abstract: A shotgun shell holder for use in quickly loading a plurality of shotgun shells into the magazine of a shotgun. The holder has a wall cylindrically curved about a longitudinal axis to hold the shells. The wall has a narrow, longitudinal extending, curved base section with a front and back end. Sidewall sections curve upwardly from the base section with the free sides of the sidewall sections defining a longitudinal slot between them, the slot being opposite the base section and open at both ends. A pull is provided at the back end of the base section for use in withdrawing the holder out of the magazine while leaving the shells behind. In use, the holder is loaded with shells arranged end to end and inserted into the magazine of a shotgun. A member on the shotgun within the magazine enters the slot on the holder and prevents the shells from being withdrawn from the magazine while the holder is withdrawn using the pull.
Patent CA-2203100-A1 (CA)
Inventor: JOHNSTON RICHARD S
IPC: G02B26/10
Filed: 1995-10-02
Abstract: A miniature optical scanner (10) includes an electromagnetic drive having stationary magnets (26, 28) and stationary drive coils (22, 24) to minimize the rotational inertia of the scanner and increase the scanner's resonant frequency. The scanner is such that the resonant frequency is manually tunable as well as automatically adjustable to compensate for variables causing frequency drift. The optical scan angle is increased by employing a multiplying mirror with the optical scanner (10). For a two axis scanning system, the multiplying mirror may be formed of a second optical scanner to increase the optical scan angle relative to both of the axes.

Title: Isolation and purification of paclitaxel and cephalomannine
Inventor: PANDEY RAMESH C
IPC: C07D305/14
Filed: 1996-11-01
Abstract: A novel process for extraction, isolation and separation of taxanes, particularly paclitaxel, from natural sources such as bark, needles and twigs from Taxus species, tissue cultures, and fungi is described, wherein the taxanes are separated from the crude extracts by partitioning between polar and nonpolar solvents, precipitation in nonpolar solutions, reacting the mixture by halogenation of unsaturated taxane derivatives, followed by chromatographically separating and crystallizing taxanes from a mixture of polar and nonpolar solvents; more particularly, the process of halogenation of unsaturated side chain taxane derivatives, particularly cephalomannine in presence of paclitaxel, is described, wherein bromine is preferably added to the double bond of unsaturated taxanes leaving paclitaxel unchanged, with paclitaxel being easily separated from the mixture including the less polar halogenated taxane derivatives.

Title: Method for internal combustion engine start-up
Inventor: ROMZEK MARTIN ANTHONY
IPC: F02B3/06
Filed: 1997-08-11
Abstract: A method for engine start-up reducing white smoke and the  start-to-idle time.   The method includes the combination of producing two sub-fuel injections into the cylinders of the internal combustion engine at different points in the rotational position of at least one camshaft of  the  engine  and  reducing the  number  of  combusting cylinders in half.  The two sub-fuel injections reduce the start-to-idle time.  Once the engine is idling, the half cylinder  operation  reduces  the  white  smoke  emitted therefrom.  The two sub-fuel injections are also employed when in half cylinder operation to reduce noise.

Title: Aluminum cathode base plate with insert of dielectric material
Inventor: MACLEAN ROBERT JOHN
IPC: C25C7/02
Filed: 1997-12-12
Abstract: There is provided an aluminum cathode base plate which has an insert of dielectric material at an upper edge thereof, in the vicinity of the solution line of the electrolytic cell when the cathode is placed into such cell for the purpose of electrodeposition of zinc. The insert has a flat surface which is raised or projected above the surface of the aluminum base plate by a distance of 0.5 mm to 1.5 mm on both sides of the base plate. In this manner, when the stripping knife strikes the dielectric insert during stripping of the electrodeposited zinc sheets and then penetrates between the zinc sheets and the aluminum base plate, it will not hit and damage the perpendicular interface between the dielectric insert and the aluminum base plate. This will avoid rapid deterioration of the base plate and will significantly improve its life span.

Preferably, the spoil (6) is separated into layers of increasingly larger diameter particles. The geotextile material (8) can be carried as a roll on a padding machine or a frame attached to a tractor or other vehicle. A spreader and optionally a leveler are also provided to evenly place the geotextile material in the ditch. A tensioning device may also be provided to prevent inadvertent unwinding of the geotextile material as it is placed in the ditch (1).
