Patent CA-2231051-A1 (CA)
Title: Device for compressing a tube
Inventor: GARAY THOMAS WILLIAM
IPC: F15B15/10
Filed: 1998-05-07
Abstract: The present invention relates to a device for compressing a tube which can be used to control fluid flow within the tube, for pumping fluid, or for operating as a motor. More specifically, the invention relates to a device with a compressing member that can move along the tubing. The tubing can be easily removed from the device after operation. This can greatly simplify cleaning or replacement of the tubing. The device is very compact and economical to manufacture and maintain. The device consists of a supporting roller, a compressing roller that are driven against each other using handles. This causes a location of compression on the tube which restricts fluid flow. The handles can also be moved along the tube to cause the fluid to move within the tube. Another function of the device is to apply fluid pressure to one end of the tube. This induces a force to cause the compressing roller to move linearly along the tube.

Title: Environmentally friendly filter cartridge
Inventor: ROGERS JEFFREY E D
IPC: B01D29/21
Filed: 1996-12-19
Abstract: A filter cartridge (22) for use in a filter system (20), in which the cartridge (22) has no structural metal or plastic parts and is adapted for environmentally acceptable disposal. A pleated paper filter media is formed into a cylinder (40), and potted end caps (44, 45) at the axial ends of the cylinder hold the shape of the filter. Sealing gaskets (50, 51) are associated with the end caps (44, 45). At least one side has a radial seal formed at the outer periphery of the filter cartridge (22) to protect the associated end cap from higher a pressure region found at the outer periphery. The other axial end can have a similar radial filter in some applications, or in other applications, where flow at the end of the filter is not desired, can utilize an axial seal specially configured to protect the associated end cap from higher pressure at the outer periphery. Maintenance of lower pressure at the respective end caps places any axial loads on the filter in tension, and thereby prevents the application of axial crushing loads on the filter cartridge.

Title: Fuel cell, separator for the same and method for distributing gas in fuel cell
Inventor: MIZUNO SEIJI
IPC: H01M8/04
Filed: 1999-02-25
Abstract: Reduced performance of a fuel cell formed of a plurality of stacked unit cells caused by unequal gas flow rates in the unit cells is avoided through the use of separators, each having a plurality of through holes extending therethrough and a recessed portion formed in a surface of each separator. In a fuel cell incorporating such separators, the recessed portion of each separator forms an in-cell oxidative gas passage, together with an adjacent cathode. An oxidative gas, supplied from an external device into the fuel cell, is distributed from an oxidative gas supply manifold formed by holes of the separators, to the in-cell oxidative gas passages. The oxidative gas is then collected in an oxidative gas discharge manifold formed by holes of the separators, and conveyed out of the fuel cell by the discharge manifold.      During the passage through each in-cell oxidative gas passage, the oxidative gas flows via an oxidative gas transit manifold formed by holes of the separators.

Patent CA-2277086-A1 (CA)
Inventor: BEYER CURTIS D
IPC: C10L5/44
Filed: 1998-01-14
Abstract: Processes are provided herein for making a combustible article. One such process involves mixing finely-divided plant-fibre particles and finely-divided synthetic polymer, namely finely divided polyethylene particles or finely-divided polypropylene particles, to form a substantially-uniform mixture. The finely-divided, synthetic plastic materials are of a size which is small enough to be distributed in the substantially-uniform mixture so as to have great surface contact with the plant-fibre particles and to improve the bonding strength of the substantially-uniform mixture. The proportion of the finely-divided, plant-fibre to the finely-divided synthetic polymer is sufficient to provide a combustible article and to produce a structurally-solid composite without the use of any binder. The process further comprises heating the substantially-uniform mixture to a temperature below a flash paint of the mixture to form a pressable hot mixture. The flash point is defined as being a temperature which is sufficient to ignite, or at least to cause the substantially-uniform mixture to begin smoldering, at a temperature which is below the melting point of the synthetic plastic at one atmosphere pressure. The process further comprises pressing the pressable hot mixture in a briquette press at a pressure between 200 and 250 Kg/cm2, thereby to cause penetration of the finely-divided synthetic polymer particles into voids of the plant-fibre particles.      This produces a structurally-solid composite (or log) without the use of binders. Such log has been found to burn longer and better than a comparable wood log, with less evolution of particulate matter. Such logs produce any power ashes, do not produce sparks, and burn well when mixed with other fuels.
