Title: Catalytic reactor with u-tubes for improved heat transfer
Inventor: STERENBERG DAVID J
IPC: H01M8/06
Filed: 2002-01-30
Abstract: In an apparatus and method for improved operation of a catalytic reactor, a preferred reactor comprises a vessel having concentric first and second annular catalyst beds. Heat transfer fluid flows through expandable heat transfer U-tubes passing through the catalyst beds, either concurrently or countercurrently with respect to the flow of process gas through the catalyst beds. This arrangement delivers improved heat transfer between the process and heat transfer fluids and allows the heat transfer U-tubes to expand longitudinally to withstand the pressure differential between the process gas and heat transfer fluids.
Patent CA-2369494-A1 (CA)
Inventor: FITTS TODD M
IPC: B60P3/40
Filed: 2002-01-25
Abstract: A device for extending the storage bed of a vehicle and creating a storage receptacle at multiple locations on top of the storage bed. Adjustable length side walls are pivotally attached to an end wall to form an open top box. Two walls pivotally attached to each other and to the end wall allow formation of a storage receptacle when desired. The adjustability of the side walls permits the open top box, whether it is used to extend the storage bed, create a storage receptacle on top of the storage bed or both, to make optimal use of the storage space between the wheel wells of the vehicle and its raised tailgate, as well as to make optimal use of the additional storage bed space created by lowering the tailgate. Storage receptacles created by the open top box may be subdivided into multiple smaller storage receptacles.

Abstract: A floating harvesting header apparatus comprises a float pan pivotally attached at a front end thereof to the header at a front attachment location in proximity to the crop intake. The float pan extends rearward under the header and a pan actuator is attached to the float pan to selectively move the float pan up and down and maintain the float pan in a selected vertical position relative to the header such that the header can slide along the ground on the float pan. The header can float up and down independently with only a portion of the header's weight carried on the float pan. The float pan curves down from the front and then curves upward towards the rear such that when the rear end of the float pan is raised the crop intake moves lower and the contact area between the float pan and the ground moves toward the crop intake.

Patent CA-2392796-A1 (CA)
Inventor: EVANS MARK D
IPC: B60K17/10
Filed: 2002-07-09
Abstract: A control system for a utility vehicle transmission provides for operator selection of vehicle "aggressiveness," or rates of acceleration in response to operator command. The aggressiveness of a vehicle's performance can be controlled by modulating control signals to proportional control valves, which determine the transmission acceleration, according to two or more electrical ramp-up (or ramp-down) profiles, in response to an operator's acceleration command (or deceleration command). The transmission control system includes a controller, directional switches and electro-hydraulic valves which control hydraulic pressure in the servo control system of a hydrostatic transmission. The operator is provided with a two-position set switch. With the set switch in the less aggressive position, in response to an operator's command, the software in the controller provides a relatively slow current ramp to energize the control valves. With the switch in the more aggressive position, the current ramps and resultant pressure ramps are faster, thus causing more aggressive transmission operation for the hydrostatic transmission.

Patent CA-2405151-A1 (CA)
Title: Bile acid containing prodrugs with enhanced bioavailability
Inventor: COOP ANDREW
IPC: A61K35/50
Filed: 2001-04-06
Abstract: Many compounds have poor bioavailability or variable bioavailability because  of poor absorption of the compound in the small intestine. Conjugation of th e compound with bile acid to form a prodrug will increase the bioavailibility of the compound and/or reduce the bioavailability variability of the compound because of the active transport of the prodrug by the intestinal bile acid transporter and because of increased lipophilic nature of the prodrug. A linker group can be used between the bile acid and the compound. One example  of a bile acid containing prodrug is acyclovir valylchenodeoxycholate, where  valine is the linker group. Another example of this prodrug is atenolol chol ic acid amide.
