Patent CA-2360793-C (CA)
Title: Screw press apparatus
Inventor: MITANI YUKITOSHI
IPC: B30B9/12
Filed: 1999-11-30
Granted: 2006-06-13
Abstract: A screw press apparatus has frames, a screw shaft, an outside tube, a cylindrical screen, a screw blade, a supply pipe, and a cleaning pipe . Raw liquid is fed from the supply pipe via an opening of the screw shaft to the upstream region of the cylindrical space. The cleaning pipe ejects cleaning water onto the screen. Raw liquid fed from the opening to the upstream region is pressurized and carried towards the downstream region by the screw blade, and is separated into filtrate which flows through the fine holes out of the screen and a cake which moves in the cylindrical space, to be discharged from the downstream region. Sizes of the fine holes of the screen decrease gradually from the upstream region towards the downstream region.

Title: Micro-fuel cell sensor apparatus and method for modeling the sensor response time
Inventor: BEAUCHEMIN CLAUDE
IPC: G01N27/404
Filed: 2002-02-28
Granted: 2009-02-17
Abstract: An apparatus for measuring hydrogen content and partial hydrogen pressure in gas streams and a method of modeling the sensor based on the characteristics of the sensor. The apparatus includes a housing 20 with micro-fuel cell sensor 10 disposed therein. The sensor includes a sensing element having first and second gas diffusing electrodes 4-1, 4-2 spaced from one another with an acidic electrolyte disposed between the electrodes. A first gas permeable membrane 14 separates the first electrode from an external gas stream. A second gas permeable membrane 12 separates the second electrode from atmospheric air. Electrochemical charging of the first electrode occurs when hydrogen from a gas stream diffuses through the first membrane to react with the first electrode, while the potential of the second electrode remains unchanged. The potential difference between the first and second electrodes measured as current is identified to represent the sensor output. The response time of the sensor is modeled based on the characteristics of the sensor affecting the sensor response time.

Abstract: An arrangement that includes at least two PBXs interconnected by a network employs CTI ports to control operation of the PBXs. Through such control, a user can set up a telephonic presence in a visited PBX such that, to the user and to all others who interact with the user, it appears that the user is at the user's office, rather than at an office that is served by the visited PBX. This is effected by forwarding calls that are destined to the user at the user's office to the visited PBX, and by translating all dialing commands of the user at the visited PBX, and acting upon the translated commands, so as to provide the user with the features available to the user at the user's office while presenting an appearance to called parties that the user is at the user's office.

Abstract: A manually operated apparatus (35) for removal and insertion of a tool holder (20) to and from a tool pocket (12) of a magazine (10) includes two components - a multi-function insertion/removal tool (37), and a pivot bracket (38). The multi-function tool generally comprises an elongated bar (45) having a tool holder removal element (40) at one end (47) and an insertion element (50, 48) at the opposite end (61). The removal element can constitute a known pry tool having a fork portion (41) configured to facilitate insertion between the rim (13) of the tool pocket and the underside of the circumferential flange (23) of the tool holder. The insertion element of the multi-function insertion/removal tool comprises a pivot block (48) and a pressure plate (50). The pivot block includes a pivot pin (52) projecting therefrom that is configured for pivoting engagement within a channel (56) defined in the pivot bracket. The pivot bracket is mounted to the housing (17) of the tool magazine at a manually accessible location relative to the tool pockets with the open end of the channel facing away from the tool pocket. When the pivot pin of the insertion/removal tool is disposed within the channel of the pivot bracket, the pressure plate is situated over a portion of the circumferential flange of the tool holder when the holder is loosely disposed within the tool pocket. The elongated bar of the tool can be used as a lever arm to pivot the tool about the fulcrum point defined by the pivot pin and pivot bracket.  As the elongated bar is manipulated, the pressure plate is pivoted downward, bearing against the circumferential flange of the tool holder with sufficient force to overcome the pocket spring force operating against the head (21) of the tool holder.

Abstract: An expandable baffle (16) for sealing a cavity (24) of an automobile (10) is provided. The baffle (16) includes a thermally expandable sealing material (18) which has an expansion temperature similar to the temperatures achieved in specific stages of the automotive manufacturing processes (e.g., the paint bake stage ). The inventive baffle (16) further includes a support (20) for the sealing material (18) which maintains the material at the desired location within the cavity (24) until thermal expansion. The support (20) is formed of a material having a melting point higher than the thermal expansion temperature of the sealing material (18). In one embodiment, the support comprises a pair of solid, spaced-apart sidewalls (26a, 26b) that "bow" upon expansion of the sealing material (46). In an alternate embodiment, the sidewalls (62a, 62b) include a plurality of openings (64) formed therein through which the sealing material (52) flows during thermal expansion. The inventive baffles (FIGS. 2, 5, 6) are useful for providing noise attenuation and for sealing the cavity (24) from moisture and contaminants while providing a limited degree of structural reinforcement.
