Patent CA-2257128-A1 (CA)
Inventor: RAJAN VARAGUR S V
IPC: B01F5/06
Filed: 1998-12-23
Abstract: Structured packing for mass-exchange or energy-exchange processes uses a stack of parallel, flat sheets forming flat channels therebetween. A number of tabs extends between adjacent pairs of sheets to form both bridges for fluid flow and spacers for structural rigidity of the packing. Some of the tabs serve predominantly to divert fluid over the entire surface of a given sheet to prevent so-called channeling, while other tabs are disposed to predominantly enhance fluid transfer between the adjacent sheets. Fluid communication between both sides of each sheet is facilitated due to perforations caused by the manufacturing of the tabs. The design allows for the use of very thin sheets resulting in a light-weight packing assembly.

Title: Valve cage and ball for a reciprocating pump
Inventor: CONN KENNETH S
IPC: F04B53/12
Filed: 1999-03-02
Abstract: An improved ball-type check valve is provided for a reciprocating pump. The valve is an assembly having a cage containing the ball and a ball stop at the cage's fluid outlet, a ball seat and a seat retainer. A contiguous bore is formed therethrough from a fluid inlet at the retainer to the fluid outlet. The bore has an inside wall which is formed of three continuous profiles. The diameter of the bore diminishes from the fluid inlet of the seat retainer to the ball seat, then increases in the cage to the fluid outlet. Bore transitions are substantially tangential throughout. The cross--sectional area of the cage is managed to be about twice that of the ball's area. The bore of the ball seat is maximized to be within 1/8 inch of the diameter of the ball. More preferably, the ball is hollow. Accordingly, the improved valve has a low pressure drop and can operate at lower hydraulic head before vapor-locking or reduced pumping efficiency.
Patent CA-2264501-A1 (CA)
Inventor: MALEK SHAHIN S
IPC: B25C11/02
Filed: 1997-09-04
Abstract: A device for removing staples from papers, cloth, or other material without tearing or mutilating the material. The device utilizes a heel of palm to finger gripping action to facilitate a more natural action for removing staples. Staples are extracted by way of a jaw which opposes a wedge-shaped piece (16) to an abutting plate piece (21), which straightens the staple while simultaneously pulling it out of the paper in a perpendicular direction. The wedge-shaped piece (16) includes a portion where its width and thickness increase to dimensions wherein the sum of the width plus twice the thickness exceeds the total length of the three sides of the staples being removed, thus facilitating complete extraction.

Title: Isothermal flow controller for air sampler
Inventor: HALL PETER M
IPC: G01N1/24
Filed: 1999-04-06
Abstract: A method and apparatus for measuring gas flow in a gas sampling device including a vacuum pump which generates pulsations and the gas flow is disclosed. The exhaust from the vacuum pump is passed through a tube having an internal diameter of about 1 mm to about 5 mm, and the length of about 10 mm to about 150 mm under substantially isothermal conditions. Pulsations in the gas flow are dampened in the pulsation damper located at the upstream end of the tube. The pressure is measured at the upstream end of the tube and the gas flow is derived from a predetermined relationship between the gas flow and the tub under substantially isothermal conditions and the upstream pressure in the tube, the large bore of the tube, allows dust particles to pass through the system rather than clog up small air passage ways. The method and apparatus of the invention provide a simple means for measuring air or gas sample flow by neutralising the effect of the back pressure caused by the pump strokes.

Filed: 1998-03-17
Abstract: The centrifugal cleaner (20) of this invention is of the type having an inverted cylindrical cone (36), with a tangential inlet (34) at the top and an outlet at the bottom (26). The improvement consists of placing a ring (22) or flow smoothing means on the inside surface of the cylindrical cone about onehalf the diameter of the base of the cone (36) down from the inlet. The ring (22) forces the stock injected into the centrifugal cleaner (20) to flow towards the axis of the cone away from the inside cone wall. Once the stock passes over the dam (22) it once again flows to the inner wall of the cone (36). The stock, in being forced to flow over the ring (22), is made uniform, eliminating spiraling of the flow which has been found to decrease the efficiency with which separation within the cleaner is accomplished.
