Patent CA-2116744-C (CA)
Title: Joint connector
Inventor: CHISHIMA MASAMITSU
IPC: H01R31/08
Filed: 1994-03-01
Granted: 1997-03-11
Abstract: This invention aims to provide a joint connector which makes it easy to insert a tool therein upon detaching a female terminal therefrom and prevents a locking finger from being deformed and impacted.  A locking finger (1d) is arranged inwardly below an outer face of a side wall (1b) of a connector housing (1).  The side wall (1b) is provided on an outer face with an outwardly slanted portion (1h) which inclines and extends outwardly from an end face (1e) opposite to a distal end of the locking finger to the outer face.  The slanted portion (1h) guides a tool (5) to insert it into the connector housing (1).  An upper end of the slanted portion (1h) becomes a fulcrum for the tool and thus a distance between the fulcrum and an acting point of the tool becomes longer.  In order to prevent a short-circuit due to a leak between branched circuits, a coupling portion (25a) of a shorting plate (60) abuts on a distal end of a side wall (12) of the connector housing (1) so that the distal end limit an insertion position of the shorting plate (60).  The connector housing (1) includes first side walls (12a, 12b, 12d) the distal ends of which abut on the coupling portions (25a) of the shorting plates (60A, 60B) for a divisional shorting use and a second side wall (12c) the distal end of which abuts on the coupling portion (25a) of the shorting plate (60) for an all pole shorting use.  In order to avoid interference upon connecting alternately electrical wires directed in opposite directions, a joint chamber (115) is provided between piled terminal accommodating chambers (13), which are communicated with the joint chamber through apertures (112).  The shorting plate (60) is inserted into the joint chamber (115) to confront a given aperture (112).  A female terminal (2) is provided with a tongue piece (22c) which elastically contacts with the shorting plate (60) through the aperture (112).  When the terminal (2) is inserted to the terminal accommodating chambers (13) having openings (131) directed alternately in the reversed directions, the tongue piece (22c) contacts with the shorting plate (60) to electrically interconnect them.  Since the chamber (13) may be arranged through the aperture (112) adjacent to the joint chamber (115), the chamber can be directed in any direction.  In order to use electrical wires having different diameters, the connector housing (1) is provided with terminal accommodating chambers (13) having different sizes so that the housing can simultaneously accommodate electrical wires (91 and 92) with large and small diameters.  Since a contacting portion (22) of each terminal (2) has a common shape, the chamber (13) can accommodate either large or small diameter wires.

Title: Face seal with angled and annular grooves
Inventor: SEDY JOSEF
IPC: F16J15/34
Filed: 1994-09-01
Granted: 2005-01-25
Abstract: A non-contacting grooved face seal assembly (10) for a shaft rotating at a high pressure and high spend with a combination of two groove patterns on one of the two sealing faces (17, 18; 118) of mating sealing rings (16, 18; 119); one pattern being relatively deep angled grooves (34; 134), and the other pattern being a relatively shallow annular groove (44; 144). The relatively deep groove pattern is optimized for hydrodynamic operation and on shaft rotation pumps the sealed fluid between the sealing faces to set the running clearance. The relatively shallow pattern is designed to hydrostatically prevent a friction lock of the sealing faces at starting and stopping of shaft rotation by admitting controlled amount of sealed fluid between the sealing faces (17, 18; 118) when the shaft is at or near to a stationary condition.

Title: Processes of retaining chelant-containing effluent within pulp bleach plants
Inventor: GUO RUIJIN
IPC: D21C11/00

Granted: 2001-08-21
Abstract: Improved environmentally acceptable process for retaining chelant-containing effluent within pulp bleach plants, particularly total chloride-free bleaching sequence plants using a chelating agent closed re-cycle process. The process involves treating a pulp liquor in an acidic or near neutral stage with an effective chelating amount of a chelating agent to form a soluble, chelated metal species; removing the pulp to provide a chelated metal species-containing solution; treating this solution in an alkaline stage in the presence of sufficient Ca ions with an effective amount of an alkaline liquor to effect displacement of metals from the chelated metal species and precipitation of the metals as solids in alkaline solution; removing the solids from the alkaline solution to provide a metal-free, chelating agent-containing solution; and recycling the metal-free solution to the pulp liquor.

Filed: 1997-02-07
Granted: 2000-10-03
Abstract: A closed-loop control system controls introduction of either water or hydrogen into a furnace region where a part is subjected to an elevated temperature to accomplish a heat treatment process.  The heat treatment process causes the part to participate in reduction and/or oxidation reactions which remain in balance at the elevated temperature so long as a hydrogen/water ratio set point is maintained.  The system includes an oxygen probe in communication with the furnace region for providing (i) an oxygen output indicative of sensed oxygen concentration within furnace region, and (ii) a temperature output indicative of temperature therein. A controller determines from the oxygen output and temperature output, a measured ratio of hydrogen to water within the furnace region and compares the measured ratio with the hydrogen/water ratio set point, and provides a correction signal output in accordance with a determined difference between the measured ratio and the ratio set point. A flow controller is responsive to the correction signal output to provide a flow of at least one of hydrogen and water to the furnace region to move the hydrogen/water ratio towards said ratio set point.
