Abstract: A wheel assembly provides an expanded air-pressurization chamber to increase the load capacity of the mounted tire. The wheel assembly includes an axle shaft, including flange plates mounted at opposite ends of the shaft and a mounting disc attached to each flange plate. There is an annular-shaped locking ring attached to each mounting disc. A cylindrical insert assembly is mounted between the pair of locking rings. A central section is defined in the tubular body extending between a pair of annular flange wall portions and includes an array of holes. The tire bead at each inner edge of a tire is located within the annular bead-receiving channels formed between the locking ring and insert assembly. A dual air-pressurization chamber is formed, one radially outward and the other radially inward of the tubular body of the insert assembly.

Abstract: The present invention discloses an endoscopic sleeve apparatus for mitigating propulsion-related epithelial tearing, said apparatus comprising: an elastomeric, pliable, and rotatable sleeve for encasing an elongated shaft member of an endoscope; any one of a right-turn or left-turn helical threading disposed on the outer surface of the sleeve from a proximal base of the endoscope and radially extending to a distal tip of the endoscope; a distal tip port opening configured for allowing at least one channel and, or lumen axially disposed within the elongated shaft member of the endoscope to be engaged to the distal tip port opening for release and, or capture of any agent; a proximal end housing comprising at least one motor coupled to at least one actuator gear, whereby said actuator is in operable communication to the rotatable sleeve via a sleeve-actuator junction seal; a finger-led control disposed on a surface of the proximal end housing and operably coupled to the motor and, or actuator gear for triggerin

Abstract: A tire assembly includes a tire having an annular tread between and connected to outer edges of opposed first and second sidewalls. The first and second sidewalls terminate at radially inner edges defining first and second bead sections, respectively. The tire also has a first interior wall having one edge coupled to the tread and an opposite free edge. The first interior wall is positioned between and generally parallel to and spaced from the first and second sidewalls. A first annular spacer is positionable adjacent the first bead section between the first sidewall and the first interior wall on one side of the first interior wall. A second annular spacer is positionable on the opposite side of the first interior wall. The first and second annular spacers are configured to generally maintain a spacing of the first and second sidewalls and the first interior wall relative to one another.

Abstract: A belt drive system employs variable diameter drive and driven pulleys interconnected by a flat belt and operative to vary the rotational speed of the driven pulley as in a variable speed transmission. Each pulley includes an internal fluid pressure chamber and diametrically aligned pairs of radially movable pistons or lift bars that support transverse lift rods at their outer ends. Axially spaced circular guide plates form end boundaries for the fluid pressure chamber and have radial through-slots that cooperate with arcuate slots in juxtaposed pairs of coaxial guide discs to receive opposite ends of the lift rods and effect synchronous radial movement of the lift rods in response to pressure changes within the fluid pressure chamber. An elongated flexible spring-like support member is attached at one end to a lift rod and extends in supported relation circumferentially over and about the lift rods to define a variable diameter belt support surface.
