Patent CA-2176699-A1 (CA)
Title: Mid-stream fluid sampler
Inventor: ALLAN JOHN ROBERT
IPC: G01N1/10
Filed: 1994-11-24
Abstract: A fluid sampling device which collects the initial sample of a fluid stream, discards it and collects a mid-stream sample for future analysis. When used for the collection of urine, the initial sample is collected in a hopper, which after collecting the initial sample, rotates from a first positionto a second position and discards some of the initial sample. While in its second position, a surface of the hopper diverts the mid-stream sample to the container for collection of the sample.

Patent CA-2186993-A1 (CA)
Title: Vapor compression distillation apparatus
Inventor: PITTMON LEE
IPC: F28F9/24
Filed: 1996-10-02
Abstract: A vapor compression distillation apparatus includes a vessel for containing a liquid to be distilled and a heat exchanger of the shell and tube type immersed in the liquid. The heat exchanger has top and bottom manifolds and vertical tubes surrounded by a shell. Foraminous vortex-drag induction plates extend across the shell between adjacent rows of tubes for inducing turbulence in the vortices to provide a better heat transfer from vapor passing through the shell to liquid in the tubes. Baffles are provided at selected intervals across the shell, between adjacent rows of tubes to produce a sinuous flow path for the heating medium. Steam injecting sparging tubes extend along the lower manifold of the heat exchanger to inject steam bubbles into the liquid to be evaporated. This produces turbulence in the tubes of the heat exchanger, promotes a better flow through the tubes and scrubs the tube interiors.

Title: Multi-purpose dolly-truck
Inventor: STICH RICHARD G
IPC: B62B3/10
Filed: 1996-10-07
Abstract: A multi-purpose, movable apparatus (henceforth dolly-truck) for conveying objects, such as, for example, a five-gallon, cylindrical, industrial bucket, is described.  A dolly-truck includes a one-piece, molded plastic base having caster wheels and truck wheels.  The caster wheels are mounted on a lower surface of the base and provide short distance rolling movement capability in the upright position.  Connected to the base are two truck support arms which support an axle with two truck wheels.  The truck wheels provide a hand truck capability for negotiating stairs, bypassing obstacles and an omnidirectional capability in conveyance of objects.  Centered on the base is a retaining wall for receiving and holding objects. Connected to, and integrated into the retaining wall is an adjustable handle for conveying the dolly-truck by hand.  The handle can be used to move the dolly-truck on the caster wheels as a conventional dolly, or alternatively on the truck wheels as a conventional hand truck.  The base of the dolly-truck is surrounded by an optional kick ring which allows the dolly-truck to be conveyed by foot.  An annular surface of the base outside the retaining wall and inside the kick ring forms a spill surface that prevents spillage of liquid from an open bucket onto the floor.

Title: Knife projection sensing system
Inventor: MIERAU CAMERON DEAN
IPC: B27L11/00
Filed: 1997-07-22
Abstract: A knife projection sensing system for cutting machines having a rotatable surface adapted to retain a plurality of cutting knives.  The system employs a plurality of sensors mountable to the cutting machine to be stationary with respect to the rotatable surface. The sensors generate a signal capable of indicating the position of each cutting knife as the knives rotate past the sensors.  A microprocessor in communication with the sensors analyzes the signal generated to determine the projection of each knife from a reference surface and to determine if the projection of at least one of the plurality of cutting knives deviates outside preset desirable limits.  The projection status of the knives is communicated to an operator by a light display or paper printout.  The system can be used to ensure that knives are correctly installed in the cutting machine and to monitor knife position during normal operation.  The system can also be used to determine when knives need changing for sharpening.  If the projection of the knives exceeds preset limits, the system will automatically shut down the cutting machine to prevent damage.

Title: Procede de fabrication de plombs de chasse
Inventor: DORAN WILLIAM J
IPC: B22D25/02
Filed: 1996-02-01
Abstract: L'invention porte sur un procédé de fabrication de plombs de chasse non toxiques faits d'alliages, notamment à base de bismuth, et destinés à remplir les cartouches de chasse. Un alliage métallique en fusion, par exemple de bismuth et d'étain, est injecté dans un moule de manière à former un ensemble rectangulaire dense et régulier de plombs. Le rapport entre les baguettes de coulée et les plombs est réduit, et la production de plombs par coulée est accrue puisque les plombs des colonnes et rangées voisines sont mis en contact par de petits canaux d'interconnexion. Lesdits canaux permettent au métal de se répartir entre les plombs et de passer d'un plomb à l'autre. Le métal en fusion peut ainsi contourner les obstacles qui limitent le nombre de plombs par coulée. L'écoulement du métal dans le moule se trouve par ailleurs amélioré si on rabote la surface du moule d'une faible quantité de manière à former une feuille mince d'alliage entre les plombs.
