Abstract: A footwear attachment device for releasable mounting on primary footwear, e.g., a boot or shoe, to provide enhanced traction. The primary footwear has an upper including a toe portion and a heel portion, a sole including a fore-foot portion and a heel portion.  The attachment device comprising an integral member having a mounting ring, a forefoot-sole engaging portion, a heel-sole engaging portion, and plural connecting webs. The attachment device is preferably molded of a resilient material. The forefoot-sole engaging portion and the heel-sole engaging portion of the device are each a generally planar member mounted within the bounds of the ring by the connecting webs. The ring is stretchable to enable it to encircle the upper of the primary footwear to releasably mount it, so that its forefoot-sole engaging portion is engagement with the forefoot portion of the sole of the primary footwear, and its heel-sole engaging portion is in engagement with the heel portion of that sole. The forefoot-sole portion and the heel-sole portion of the attachment device each have a ground engaging surface, e.g., a multitude of organized or disorganized fibers, plural ridges, grooves, cleats or combinations thereof, for providing a desired type of traction. A pull tab is also provided on the ring to facilitate the mounting of the ring on the primary footwear. A disposable gritted pad having a pressure-sensitive adhesive is provided for releasable mounting on the ground engaging surface of the attachment device or on the sole of the primary footwear to enhance the traction provided thereby.

Title: Anti-theft seat belt
Inventor: CASTELLANOS MARIE-PAULE
IPC: B60R25/00
Filed: 1999-05-25
Abstract: A seat belt arrangement selectively enables vehicle drivability when a buckle member carried on a restraint belt is engaged with a mounted buckle receiving mechanism. The buckle member is removable from the restraint belt, and may be hidden or carried on the person of the user when leaving the vehicle unattended, thereby providing a vehicle anti-theft feature. The detachable buckle plate member is advantageously keyed to the buckle receiving mechanism such that only a particular buckle plate member will operate a correspondingly keyed receiving mechanism with which it is brought into engagement. Such keying may be provided mechanically in the form of a special shape such as employed in the construction of standard keys, or may employ other recognizable identifying factors, such as digitized, audio, optical or other discernable discrete data communicated between the plate and locking members. The buckle receiving mechanism correspondingly enables correct operation of the vehicle in response to recognition of the proper keyed buckle plate member when lockingly engaged therewith.

Title: Oil return from evaporator to compressor in a refrigeration system
Inventor: CAREY MICHAEL D
IPC: F25B43/02
Filed: 1998-01-28
Abstract: A refrigeration system (10) employing a screw compressor (12) and a falling film evaporator (20) makes use of high-side pressure to drive lubricant, which escapes the compressor (12) and collects as a lubricant-rich mixture of lubricant and refrigerant in the system evaporator (20), back to the compressor (12). The mixture is cyclically exposed to high-side pressure for a period of time which (i) varies in accordance with the difference between a sensed condenser-related pressure and a sensed evaporator-related pressure and (ii) is calculated to maintain a predetermined oil concentration in the lubricant-rich mixture in the evaporator (20) so as to minimize the oil return process.

Title: Cytokine related treatments of disease
Inventor: AVERETT DEVRON
IPC: A61K31/7042
Filed: 1998-01-13
Abstract: Nucleosides and other compounds to selectively modulate Th1 and Th2 responses relative to each other in the treatment of disease. In one aspect of the invention, administration of a nucleoside or other compound reduces the dosage at which a primary drug is administered. In another aspect of the invention, an abnormality reflected in increased response in one group of cytokines is treated by administering a nucleoside or other compound which increases response in another group of cytokines. In yet another aspect of the invention, a patient is prophylactically treated by administering a nucleoside or other compound which selectively reduces Th1 activity without significantly reducing Th2 activity. In yet another aspect of the invention, a nucleoside or other compound is administered to a patient at a dose which reduces the patient's GTP pool to a degree that selectively reduces one of the Th1 or Th2 response without significantly reducing the other response. Controlled release dosage forms are particularly contemplated to achieve that result.

Patent CA-2289240-A1 (CA)
Inventor: FRIGGSTAD TERRANCE A
IPC: A01B73/06
Filed: 1999-11-10
Abstract: An agricultural implement, having a tool bar that is pivoted forwardly to initiate the conversion of the implement from a working position toward a transport position, including left and right wing members extending in opposing directions to respective distal ends, is provided with a lift assist mechanism to support the distal ends of the wing members as the tool bar is pivoted forwardly to an intermediate transport position. The lift assist mechanism includes a frame pivotally mounted to each respective wing member, a lift assist wheel providing ground-engaging support for the wing member, and a lift assist actuator that controls the pivoted movement of the lift assist mechanism to maintain the lift assist wheel in supporting contact with the ground until the tool bar has been rotated approximately 60 degrees from the lowered working position toward the raised intermediate transport position. A cable extends from the lift assist mechanism to a toll bar lock apparatus to release the tool bar lock only when the lift assist mechanism has been positioned for proper support of the wing member during the pivotal movement of the tool bar from the intermediate position rearwardly into the working position. A hydraulic circuit controls the operation of the lift assist actuators and the tool bar actuators to effect a coordinated action between them so as to maintain proper support for the wing member during the pivotal movement of the tool bar.
