Patent CA-2227622-C (CA)
Inventor: SEN ASIM K
IPC: F03G7/08
Filed: 1998-04-02
Granted: 2002-10-22
Abstract: This invention relates to a new and useful improvements of an earlier scheme patented by this inventor (Canadian Patent No. 1,245,992, issued December 6, 1988) for generating electricity using gravitational energy. The improved scheme uses a set of massive underground spinning wheels, wherein each wheel is geared to a large driving wheel requiring a lower input torque, which wheel is then fitted with a mechanism to receive and transmit gravitational torque pulses from a passing vehicle to keep the wheels in motion. The above transmission mechanism consists of a stepping board, a cylindrical rod and a movable striking head with a toothed jaw attached to the lower end of the cylindrical rod by a hinge fitted with a torsional spring. The upper end of the cylindrical rod which protrudes above the ground surface is rigidly connected to the moving end of the stepping board and both are kept in their initial upward position by means of a "recocking" compression spring. Also, the upper jaw of the striking head which initially remains closed and attached with the cylindrical rod due to the spring pressure, is designed to rest on a set of matching teeth.  The electricity is generated by using each spinning wheel in combination with an appropriate gear system to act as the prime mover of an alternator.

Title: Vascular tissue sealing pressure control and method
Inventor: KENNEDY JENIFER S
IPC: A61B17/12
Filed: 1996-08-12
Granted: 2001-05-08
Abstract: A clamping force mechanism (10) and its method of use with electrosurgery allow a user to seal and/or joint patient's particular vascular tissue; the mechanism is elongate with user and patient ends (14). An actuator (15) is at the user end (13) and the effectors are at the patient end (14). Each effector has a face of an area to contact the particular vascular tissue. A lost motion connection (18) transfers user actuation to the effectors to hold a predetermined clamping force during electrosurgical tissue sealing. A yielding member (19) in the loss motion connection clamps the particular tissue between the faces with a predetermined force. The yielding member (19) is a spring (20), slip clutch (36) or hydraulic coupling possibly near the actuator (15).  An active electrode is carried on one end effector and a return electrode (24) contacts the tissue so an electrosurgical energy supply (25) connected thereacross delivers energy therebetween. A feedback circuit (27) responds to parameters of energy delivered to tissue. A temperature sensor (28) on one face and an impedance monitor (29) respond to energy delivered. A control (30) applies energy to held tissue to seal and/or join it. The method transfers user actuation of the effectors with the lost motion connection (18), maintains clamping force while sealing and applying electrosurgical energy to seal and/or join held tissue. Energy is applied to a temperature or an impedance. The method shifts the yielding member (19) so the opposing faces (17) clamp the particular tissue therebetween with the force from the spring (20), via a transfer rod or by the hydraulic coupling or the slip clutch (36) for a range of pressure.

Abstract: A multimedia transaction between a local and a remote transaction systems (10 and 12) is facilitated by a multimedia interface (16) within each system. The multimedia interface (16) associated with each transaction system serves to signal a telephone (18, 20) associated with the other transaction system to go off hook while the transaction systems are exchanging data when a voice conversation between the transaction systems is desired. Further, the multimedia interface (16) serves to convert the analog speech from the telephone of its associated transaction system into digital voice packets for transmission with the digital signals to the other the transaction system. Also, each multimedia interface converts the digital voice packets received at its associated transaction system from the other transaction system into analog voice information for receipt at the associate telephone.

Title: System and method for measuring channel quality information
Inventor: BALACHANDRAN KRISHNA
IPC: H03M13/23
Filed: 1998-07-30
Granted: 2003-02-18
Abstract: A system and method to measure channel quality in terms of signal to noise ratio for the transmission of coded signals over fading channels. A Viterbi decoder metric for the Maximum Likelihood path is used as a channel quality measure. This Euclidean distance metric is filtered in order to smooth out short term variations. The filtered or averaged metric is a reliable channel quality measure which remains consistent across different coded modulation schemes and at different mobile speeds. The filtered metric is mapped to the signal to noise ratio per symbol using a threshold based scheme. Use of this implicit signal to noise ratio estimate is used for the mobile assisted handoff and data rate adaptation in the transmitter.

Granted: 2001-12-11
Abstract: This application relates to an apparatus for containing and filtering rinse water, sediment and aggregate resulting from washing the hopper and discharge chute components of a concrete truck at a construction site following use, The apparatus comprises a container removably mountable on the end of the discharge chute, the container having an open upper end, a screen removably positionable within the container and an outlet located in a lower portion of the container below the screen. The apparatus further includes a pump mountable on the truck, the pump having a suction hose extending between the container outlet and the pump; and a discharge hose extending from the pump to an open end discharging into the mixing drum. When the pump is operating, rinse water and relatively small particle size sediment flushed down the chute and into the container is automatically conveyed through the suction and discharge hoses into the mixing drum. The screen has openings approximately 1/4 inches in diameter to trap relatively large particle size aggregate thereby preventing clogging of the pump fittings. The apparatus avoids the need for a designated truck wash-off station at the construction site and prevents contamination of the site or adjoining waterways with cementitious debris.

Granted: 2007-01-02
Abstract: A spent zeolite-containing hydrocarbon cracking catalyst is treated by regenerating it to remove carbonaceous deposits. A portion of the regenerated catalyst is withdrawn from the circulating catalyst inventory of a hydrocarbon processing unit and slurried with a liquid containing an activating agent to solubilize and/or dislodge contaminants which block the pores of the zeolite and adversely affect the activity of the catalyst. The slurry is agitated to dissolve or dislodge the contaminants from the zeolite pores, and the agitated slurry, without being permitted to settle, is transferred to a fluidized drying zone where the liquid and solubilized and/or dislodged contaminants are removed from the treated catalyst which has a level of cracking activity higher than that of the catalyst in the circulating catalyst inventory. The treated catalyst is then recycled to the unit and contacted with a hydrocarbon feedstock under cracki ng conditions.
