Abstract: A track for a motor-driven or pedal-powered snow vehicle designed to emulate the steering and balancing characteristics of motorcycle and bicycle wheels while providing longitudinal and lateral traction in a variety of snow conditions. The track comprises an endless-loop belt with traction paddles attached to the belt and extending laterally beyond the sides of the belt to form lateral projections for traction with the snow when the snow vehicle is leaned in turning or when crossing steep side-hills. The traction paddles may have paddles with blunt tips having convex curvature to allow the snow vehicle to balance on hard-pack snow and ice. Bearing clips are attached to the lateral paddle projections for bearing upon the vehicle's track slides to support the track at its lateral edges, thereby enabling the snow vehicle to be steeply leaned in turning without the track flexing and sliding sideways.

Title: Implantable delivery device with self adjustable exit port
Inventor: BROWN JAMES E
IPC: A61M31/00
Filed: 1998-03-10
Abstract: A delivery device having a first chamber containing an osmotic agent, a membrane forming a wall of the first chamber through which fluid is imbibed by osmosis, a second chamber containing a beneficial agent to be delivered, and a moveable piston separating the two chambers. In fluid communication with the second chamber is an orifice which comprises a slit valve. In the presence of pressure, the beneficial agent pushes through the slit, opening up a channel for delivery of the beneficial agent and creating flow. Because the slit remains closed in the absence of flow (or when the pressure is below the pressure required to open the slit), back diffusion of external fluids is eliminated when the slit is closed, which prevents contamination of the beneficial agent in the second chamber by external fluids. In addition, forward diffusion of the beneficial agent out of the capsule is prevented when the slit is closed. The slit valve opens only to the minimum dimension required to allow the flow generated by the osmostic pumping rate. The slit valve also allows a flow path to open around any obstruction in the slit valve to prevent clogging.
