Patent CA-2197198-A1 (CA)
Inventor: HYPPANEN TIMO
IPC: F23C10/10
Filed: 1995-08-16
Abstract: A fluidized bed reactor system includes a reaction chamber (112) comprising a circulating (fast) bed, with a first grid (114) for the introduction of fluidizing gas, and a bubbling (slow) fluidized bed (116) having a second grid (120) for introduction of fluidizing gas. The second grid is mounted below the first grid. First (122) and second (132) interconnections are provided between the circulating and bubbling beds. Particles flow from the circulating bed through the first interconnection to the bubbling bed, and vice versa for the second connection. The interconnections are positioned with respect to each other so that the pressure and density conditions within the bed are the sole mechanisms that provide the driving force to control the flow of particles from the circulating bed to the bubbling bed. An indirect heat exchanger (128) may be located in the bubbling bed for cooling particles, and various constructions of partitions (130) may be provided for dividing up the bubbling bed and defining the interconnections.

Patent CA-2204956-A1 (CA)
Inventor: WEBER JAMES L
IPC: E21B43/12
Filed: 1997-05-09
Abstract: A rotor placer is located within an oil well for stabilizing the rotor of a progressive cavity pump. A tubular housing is connected between the production string and pump stator. A driveshaft is installable within the housing and is connected between the rod string and the pump rotor. The driveshaft latches into a cylindrical sleeve installed concentrically within the housing. The housing is distended outwardly to accept the sleeve which has a bore similar to that of the production tubing. Bearings are interposed in the annulus between the sleeve and housing for concentrically and axially stabilizing the rod string. The sleeve is sealed against the housing to protect the bearings. A passageway is formed in the driveshaft to bypass pumped well fluids around the bearings. The driveshaft-to-sleeve latch comprises a plurality of axially-extending and interconnected slots formed in the inside wall of the sleeve and radially outward biassed pins extending from the driveshaft. Every second hole locks the pin within the slots, and every alternate hole contains wedges for displacing the pins radially inwards and thereby disengaging the pins from the slots so that the driveshaft is released from the sleeve.

Title: Method and apparatus for measuring loads in a common channel signalling link
Inventor: LEMIEUX YVES
IPC: H04M7/06
Filed: 1995-12-14
Abstract: A method and apparatus for monitoring the load on a communications link (28) in a common channel signalling system connecting an exchange (10) in a telephone network to regional equipment such as a remote subscriber switch (12) or a remote cellular base station (64). The length indicator field (54) of each signal unit (36, 38, 40) transmitted over the reserved channel of the communications link is monitored (82) by the exchange to determine the number of bytes of message data being transmitted over the link during a predetermined time period. The load on the communications link is identified by taking the ratio (92) of the determined number of bytes (88) to the number of full value bytes (90) capable of transmission over the communications link during an identical time period. The determined load ratio is compared (98) to a predetermined threshold level to identify an overload condition in response to which the exchange relieves the overload (100) by spreading the messages to other links, discarding low priority ones of the messages, or controlling message flow over the link as necessary.

Patent CA-2212915-A1 (CA)
Inventor: TRAVAGLINI NICK
IPC: A61C17/02
Filed: 1997-08-13
Abstract: A compact, mini-capacity heater suitable for use in a dentist's office has an electric heating element, an on/off switch, thermostat and thermometer.  The miniature heater can be located at the dentists work station, for providing air or water in treating a patient, while minimizing the length of connecting hose required and the temperature drop of the heated fluids.  Hermetically sealed flow paths for the water and air eliminate any likely bacterial infection, such as "Legionaires disease".  Use of mini-connectors enable rapid interposition of the heater into existing micro-tube lines, substantially without disruption in air and rinse water supply.  Use of a copper inner body provides excellent heat exchange capability, while threaded mini-connectors eliminates soldered connections, thus avoiding aluminum and lead contamination.  Multiple outlet connections can be used to supply more than one chair and/or to power and cool air-driven devices, such as drills and grinders.
