Patent CA-2134951-A1 (CA)
Inventor: PHILLIPS PAUL E
IPC: F16K21/18
Filed: 1994-11-02
Abstract: A two-stage float actuated shut-off valve for use in underground fuel storage tanks utilizes a drop tube coaxially mounted within the storage tank fill pipe. Fuel flowing into the tank is passed through the drop tube which projects downwardly into the interior of the tank to a valve housing located at the lower end of the drop tube.  Floats slidably mounted in a recessed area in the housing outside of the drop tube within the tank independently operate pivoted valve doors to a closed position within the valve housing, a lower float closing one valve door to block a major portion of incoming fuel flow passage when the level of fuel in the storage tank reaches a predetermined first level and a second upper float causing the secondary valve door to overlap an aperture in the main valve door to almost completely close the flow of fuel to the tank.
Patent CA-2134962-A1 (CA)
Inventor: SCHUTTE ROBERT
IPC: C09K23/54
Filed: 1994-11-01
Abstract: A dispersant, such as sodium silicate, is added to the process water of the hot water extraction process which recovers bitumen from oil sands. The dispersant disperses the ultrafine (less than 300 nm) particles, to reduce the formation of flocs and sludge in the tailings pond. The volume of the pond is such that the retention time of process water is sufficiently short (less than 6 weeks when using sodium silicate) to avoid reforming flocs from the dispersed ultrafines. The ultrafines content in the process water builds up as the water is repeatedly recycled from the pond to the extraction process. The ultrafines content stabilizes at a steady state level as some ultrafines are continuously removed from the water supply when the tailings are delivered onto the "beach" of the pond and become trapped in the sand.

Title: Server detection of client process termination
Inventor: HURAS MATTHEW A
IPC: G06F15/163
Filed: 1995-04-03
Abstract: A service provider for use in a client-server system which is capable of detecting the abnormal termination of a client process is disclosed. The service provider does not require a dedicated process for polling client processes in order to verify their status. Rather, a semaphore, which is used in conjunction with a shared memory segment for communication between a client process and the service provider, is initialized in such a manner that the operating system will automatically increment the semaphore in the event the client process is terminated. Thus, the semaphore will be incremented either when the client process deliberately increments the semaphore in order to notify the service provider that the client process has written data to a shared memory segment, or the semaphore will be incremented by the operating system in the event the client process terminates. A test flag is established in shared memory in order to differentiate whether the semaphore was incremented by the client process, or by the operating system. The client process will set the flag only when the client process increments the semaphore. Therefore, whenever the semaphore is incremented, the service provider will test the condition of the flag, and terminate resources allocated to the client process if the flag is not set.

Title: Latching arrangement for window or door assemblies
Inventor: SLOCOMB COLIN
IPC: E05C3/14
Filed: 1995-04-04
Abstract: A latching arrangement for selectively locking together and unlocking two components in a window or door assembly includes a hollow profile as one of the components with a hole extending through a contact wall of the hollow profile.  The other component has an abutting wall juxtaposed the hollow profile.  A snap-in lock member is assembled to the hollow profile by means of a retainer plate having a split stud with camming surfaces which move through the hole until the camming surfaces pass completely into the hollow interior.  An undercut on the stud engages the inner surface of the hollow interior of the profile while an engaging surface on the retainer plate from which the stud extends engages the outer surface of the hollow profile.  The retainer plate has a locking surface on the same side of the retainer plate as the stud.  A handle on the retainer plate permits the lock member to be rotated about the stud so that the locking surface can be selectively moved from a locking position in contact with the abutting wall of the other component or to an unlocking condition out of contact with the abutting wall.

Title: Method and system for improved fuel system performance of a gaseous fuel engine
Inventor: WALSER MICHAEL W
IPC: F02D41/00
Filed: 1994-03-11
Abstract: An improved gaseous fuel delivery system and method (10) to improve performance of a gaseous fuel engine (30) by variably maintaining gaseous fuel pressure to the gaseous fuel engine (30). From a storage device (12), gaseous fuel flows to fuel pressure regulator (16) that variably and dynamically reduces the fuel pressure from the storage pressure and maintains the gaseous fuel pressure at the desired controlled supply pressure. Regulator controller (20) controls the fuel pressure regulator (16) in response to signal inputs (28, 34, 44, and 54) and maintain the gaseous fuel at the controlled supply pressure. Signal inputs (28, 34, 44 and 54) used by regulator controller (20) are derived from sensors such as fuel pressure sensor (24), an engine speed and/or intake manifold pressure sensor (34), fuel temperature sensor (42), and fuel composition sensor (52). The result is substantially improved fuel system dynamic range and the ability to control gaseous fuel supply to the gaseous fuel engine to provide improved fuel metering accuracy and improved engine performance and emissions.
Patent CA-2163604-A1 (CA)
Title: Electronic device housing having storage portion
Inventor: DEGUCHI MANABU
IPC: H01M2/10
Filed: 1995-11-23
Abstract: An electronic device housing comprises a cover with a locking groove, an operation portion with a locking portion corresponding to the locking groove, and a housing to which the cover is attached. The cover is slidably mounted on the housing. Both the locking groove of the cover and the locking portion have portions inclined with respect to the cover, for instance, a portion shaped as a parallelogram in cross-section. The operation portion has a portion that slides in a direction perpendicular to the sliding direction of the cover. With this sliding portion, the locking portion is slidably inserted into and withdrawn from the locking groove. When the locking portion is fitted into the locking groove so that the cover is mounted on the housing, the cover cannot be dropped from the housing. The operation portion is attached to a portion of the housing, and is moved downwardly by depressing the housing from the upper direction. When the cover is mounted on the housing and the operation portion is depressed downwardly, the locking portion fitted to the locking groove of the cover also moves downward. A wedge effect is produced by the force exerted between the locking portion and an inclined edge located opposite to the locking groove.  The cover then slides along the removing direction in response to force produced by this wedge effect. As a consequence, the cover may be removed, by simply taking it out from the housing without sliding the locking piece. Since the cover moves downward when the operation portion is depressed, the pawl of the engaging piece for preventing the cover from being dropped is automatically released from the housing and removed.

Filed: 1995-07-31
Abstract: A method and apparatus is provided for facilitating coherent communication reception. A received reference symbol coded spread-spectrum communication signal is despread with a spreading code to derive a stream of reference samples (152) and a stream of data samples (158). The channel response is estimated by utilizing the stream of reference samples (152). An offset frequency detector (443) determines an offset to be applied to the received signal via a frequency locked loop (456), while a timing control (176) compensates for slow timing drift and fast fading based on power estimates derived from the stream of reference samples (152) and or the stream of data samples (158). A rate estimator determines the rate at which the information was encoded, and the rate information is used to optimize the timing control (176), frequency offset detector (443) and channel estimator (154). Thus an improved detection of estimated data symbols from the stream of received data samples (158) is provided.
