Inventor: TEMPCO DALE A
IPC: H02B11/10
Filed: 1994-12-14
Abstract: An automatic secondary disconnect mechanism for an electrical switchgear apparatus having an enclosure and a removable circuit device is disclosed. According to a preferred embodiment, the automatic secondary disconnect mechanism comprises a guide rail mounted to the enclosure so as to extend substantially parallel to the racking motion of the circuit device; a slide member slidably mounted on the guide rail; means for locking the slide member in place on the guide rail at a point corresponding to a test position of the circuit device; and means for releasing the slide member when the circuit device reaches the test position from the disconnect position. One of a pair of mating secondary contact members is coupled to the slide member, while the other mating contact member is coupled to the circuit device.      The mating secondary contact members automatically engage as the circuit breaker moves from the disconnect position to the test position, remain engaged and move together via the slide member as the circuit breaker moves between the test and connect positions, and automatically disengage as the circuit breaker moves past the test position toward the disconnect position.

Patent CA-2148320-A1 (CA)
Title: Electrochemical deionisation
Inventor: TURNER ANDREW DEREK
IPC: C02F1/469
Filed: 1995-05-01
Abstract: An electrochemical cell (50) for deionisation utilises electrochemical ion-exchange to remove ions from a feed solution.  Under the influence of an electric field, ions are adsorbed into, are stored within and pass through a permeable layer (54, 64) of particulate ion-absorbing material and binder, the sheet being several millimetres thick.  Water from the feed solution also permeates through the layer (54, 64), so a concentrated solution of the ions emerges from the rear (58) of the layer.  The cell does not require separate sources of feed and eluant solutions and can be operated substantially continuously.  In a modified cell (70) the flow path for the feed solution passes through a highly porous ion exchanger structure (77), which may be located between two such microporous layers (54, 64).  Absorption in such a cell may be effective in the absence of an electric field, elution requiring the periodic application of the electric field.

Patent CA-2156098-A1 (CA)
Inventor: HLAVENKA RUSSEL L
IPC: F04F5/46
Filed: 1995-08-15
Abstract: A fluid injector assembly for drawing a first fluid into the flow of a second fluid. The injector assembly includes an eductor including an inlet having a plurality of openings, a first outlet port, and a first fluid passage extending between the inlet and the first outlet port. The openings are generally disposed tangentially to the first fluid passage. The inlet is adapted o be placed in fluid communication with the second fluid such that the second fluid flows through the first fluid passage from the inlet to the first outlet port. The fluid injector assembly also includes a throat having an inlet port, a second outlet port and a second fluid passage extending between the inlet port and the second outlet port. The inlet port of the throat is spaced apart from the first outlet port of the eductor forming a gap therebetween. The gap is adapted to be placed in fluid communication with the first fluid. As the second fluid flows through the first passage, the tangential openings of the eductor cause the second fluid to swirl as the second fluid flows through the first fluid passage and to form a vortex n the gap as the second fluid flows out of the first outlet port. The vortex of the second fluid creates a low pressure zone within the gap which draws the first fluid into the gap wherein he first fluid and the second fluid enter the inlet port of the throat and flow through the second fluid passage.

Patent CA-2161568-A1 (CA)
Title: Position sensor
Inventor: TAYLOR HOWARD E
IPC: G01B7/14
Filed: 1995-10-27
Abstract: A position sensor includes a coil of small diameter litz wire wound around a ferrite rod. The rod is secured in the end of a ceramic support and an end cap is secured on the other end of the rod to form a bobbin section on which the coil is wound. Two palladium silver strips are formed axially along the length of the support extending from the bobbin section to near the base of the support.      Two free ends of the coil are formed into strain relief loops and soldered to the strips. Lead wires of comparatively larger diameter are also soldered to the strips but near the base of the support. The strips establish electrical continuity between the coil and the lead wires while separating the end portions of the coil from the lead wires so as to prevent the lead wires from inducing stress into the relatively fragile coil wires.      The lead wires are threaded through a cylindrical metal housing, and the base of the ceramic support is located into a cylindrical recess in the housing to support and seal the working end of the sensor.
