Patent CA-2370679-A1 (CA)
Inventor: JENKINS STEPHEN S
IPC: B62M13/00
Filed: 2002-02-05
Abstract: A Tread Wheel Frame System drives a human-powered cycle by means of a tread wheel driving a tread of a drive wheel of a cycle rather than driving a drive wheel hub, as conventional cycles do. Most of the driving mechanism, including the tread wheel, a speed ratio mechanism, shifting means, and a power unit device, are safely located above the level of a cycle's axles where they are less likely to encounter accidental impact. The tread wheel with the power unit device also does the braking, which eliminates the need for caliper brakes or hub brakes. Accordingly, a drive wheel is lighter, without the need for a heavy hub, or a heavy rim to withstand the wear and heat of friction of caliper brakes. The tread wheel frame is uniquely designed and engineered to be light, yet strong where needed. The best mode includes many features: an energy recapture and storage system that saves energy that would be lost in braking, for assisting in going up hills; thigh levers:  extendable pedal cranks for providing more pedal leverage; a frame extension that has no cross bar, and foot room to allow easy, low-level, mounting and dismounting;  retractable stand; lean-on device; adjustable steering; and low-mass suspension.
Patent CA-2373738-A1 (CA)
Title: Fibrin polymer structure
Inventor: MARSHALL JULIAN M
IPC: A61L26/00
Filed: 2000-06-01
Abstract: In accordance with the present invention a novel fibrin polymer structure is disclosed. The novel fibrin polymer structure useful, for example, as a surgical sealant, is comprised of a plurality of discrete, droplets of polymerizing or polymerized fibrin each encapsulated by a "skin" of fibrin polymer. These fibrin-skin encapsulated droplets are applied so as to be built up one upon the other, layer by layer, to form an integral sealant structure.  The cumulative effect of the encapsulating skins of those droplets which form the sealant surface is a surface skin which unexpectedly resists cell penetration but enhances cell migration across the surface. The sealant structure of the present invention can be prepared by spray delivery of fibrin polymer forming materials wherein the time required for the materials to commence polymerizing after mixing is less than or equal to the transit time of said materials from the applicator tip to the target surface.

Title: Thermoelectric temperature controlled drawer assembly
Inventor: ZIMMERMAN ROBERT C
IPC: F25B21/04
Filed: 2002-05-03
Abstract: A temperature controlled drawer assembly incorporates a thermoelectric device and a control system to selectively heat or cool the contents of a drawer which is selectively movable into and out of a cabinet designed to be part of an end table, such as a nightstand, or other cabinet remote from a household kitchen. In a cooling mode of operation, a fin, disposed in the cabinet, draws air from inside the drawer and blows the air over a cold side of a heat sink to cool the air. The treated air is blown through plenums, back into the drawer.  At the same time, heat is drawn away from the cold side and directed out of the cabinet. The current through the heat sink may be reversed to flip the cold and hot sides of the heat sink to enable the contents of the drawer to be heated.
