Patent CA-2140765-A1 (CA)
Title: Centrifugal blood pump
Inventor: MATHEWSON WILFRED F
IPC: A61M60/804
Filed: 1993-03-12
Abstract: A low priming volume centrifugal pump comprising a disc shaped impeller (10) having opposite faces (16,18) and an  inlet  hole  (20)  centrally  disposed  therein.    The impeller  (10)  has flow channels  (12,14)  disposed on at least one of the faces (16,18) of the impeller (10) which radiate outward from said inlet hole (20).  The volume of the flow channels (12,14) is small relative to the total impeller envelope volume providing for efficient momentum transfer with a minimum of turbulence and backflow.  Thus, priming volume is reduced and flow within the pump is more efficient.  The pump can be used as stand alone device, or it can be integrated with a blood oxygenator into a common housing.
Patent CA-2141180-A1 (CA)
Title: Method for making smooth uncreped throughdried sheets
Inventor: ENGEL STEVEN A
IPC: D21H27/00
Filed: 1995-01-26
Abstract: Uncreped throughdried cellulosic webs having improved smoothness and stretch are produced by transferring a newly formed web from the forming fabric to a slower moving, high fiber support transfer fabric, preferably using a fixed gap or kiss transfer in which the forming fabric and the transfer fabric converge and diverge at the leading edge of the transfer shoe. The web is then transferred to a throughdrying fabric and throughdried to final dryness, producing a web having an improved softness due to increased surface smoothness.

The lock assembly has a bolt extendable from the mullion cavity to engage the bolt engagement assembly supported by the top fitting and hold the mullion in a fixed position.  Retraction of the bolt is controlled by a key lock assembly that allows controlled access disengagement of the bolt from the bolt engagement assembly, followed by pivoting movement of the mullion away from its upright position in the door frame.
Patent CA-2151212-A1 (CA)
Title: Underreamer
Inventor: VERDGIKOVSKY ALEXANDER VLADMIN
IPC: E21B10/34
Filed: 1995-06-07
Abstract: An underreamer which may be mounted on a core drill to allow single phase underreaming or creation of a bore hole of larger diameter beneath a pilot hole.  A plurality of levers are powered by a plurality of corresponding jacks which are adapted to exert pressure on the levers in order to cause them to extend beyond the periphery of the expander body.

Patent CA-2151915-A1 (CA)
Title: Non-contacting face seal
Inventor: SEDY JOSEF
IPC: F16J15/34
Filed: 1993-12-14
Abstract: A non-contacting face seal for shafts rotating at high speeds with improved secondary sealing means for low axial drag forces. Secondary sealing means comprise an O-ring (26) with a compliant spring element (28, 52, 56) at its outer circumference. Compliant spring (28, 52, 56) provides a controlled radial force which keeps the secondary seal (26) in a more reliable sealing contact with the seal ring (18) and the seal housing balance surface (30) but avoids excessive radial forces, typical for secondary seal located between two machined cylindrical surfaces. Low axial drag forces due to secondary seal displacements ate important for prevention of sealing face hang-up and consequent high leakage condition.

Title: Contact tray apparatus and method
Inventor: LEE ADAM T
IPC: B01D3/22
Filed: 1995-09-06
Abstract: A downcomer tray assembly for vapor liquid contact towers.      The downcomer is formed with generally semi-conical walls forming a vapor tunnel relative to the discharge region therebeneath. The discharge region is also constructed with a trough and a plurality of venting chambers upstanding therefrom for improving mass transfer efficiency. The venting chambers reduce fluid pressure to vent excess vapor from the underlying tray. The vented vapor is selectively directed into the liquid discharged from the downcomer and allowed to pass through the vapor tunnel. In this manner both entrained liquid and entrained gas can be effectively released to facilitate a stabilized vapor-liquid flow configuration.

The output mirror is mounted to reflect the image at an angle to the normal of the remote surface substantially equal to the angle the light path is offset from the normal of the panel.
Patent CA-2164894-A1 (CA)
Inventor: FERNANDEZ RICKEY J
IPC: F16D65/84
Filed: 1995-12-11
Abstract: A drag brake mechanism prevents rotation of the shaft of a truck mounted connect-disconnect, clutch-operated, power takeoff device when the clutch is in its disconnect mode, by applying a constant braking force to the shaft which cannot be overcome by inadvertent frictional forces within the discs of the clutch that may occur despite the clutch being in its disconnect mode.          The constant force selected, however, is insufficient to create undue heat during normal shaft rotation and is easily overcome when the clutch is placed in its connect mode.
