Abstract: An apparatus capable of omni-directional movement including a belt layer made of a plurality of interlocking flexible rings and a surface layer made of a laterally inelastic and longitudinally flexible material that surrounds the exterior of the belt layer. The device has a bladder located in the interior of the belt layer that provides structural support for the belt layer and surface layer and a hub that is in contact with the surface layer and is connected to an axle. Longitudinal motion occurs as the bladder, the belt layer, the surface layer, and the hub rotate together. Lateral motion occurs as the belt layer and the surface layer rotate around the bladder. Longitudinal motion is induced by a plurality of electromagnetic curvilinear motor drive rings that are located around the hub and are in contact with the surface layer.

The cache data memory module is divided into first and second cache data memory modules which are disposed on both sides of the TAG memory module, and input/output circuits of a data TLB are opposed to the input/output circuit of the TAG memory module and the input/output circuits of the first and second cache data memory modules across a bus area to reduce the line length to achieve faster processing.

Abstract: A vehicle (10) includes a pair of hybrid track assemblies (12) mounted on opposite sides of the longitudinal axis (A) of the framework (11) of the vehicle (10) for cooperating to steer the vehicle (10). Each of the hybrid track assemblies (12) includes a first lead track (14) entrained about a first plurality of wheels (16) and a second lead track (18) entrained about a second plurality of wheels (20). A plurality of first lead rollers (26) are rotatably supported in spaced and parallel relationship to one another along the longitudinal axis of the first lead track (14). A plurality of second lead rollers (38) are rotatably supported in spaced and parallel relationship to one another along the longitudinal axis of the second lead track (18). The assembly is characterized by the first and second axes of the first lead rollers (26) and second lead rollers (38) being disposed in opposite directions, i.e., a herringbone configuration.

Abstract: A light weight track system for a buoyant amphibious vehicle, the vehicle having two pontoons, the pontoons having a flat horizontal top surface and a flat horizontal bottom surface, each end of the flat horizontal top surface and the flat horizontal bottom surface being connected by a flat inclined surface, the track system including a plurality of treads connected by a single continuous drive chain assembly around the outside of each of the pontoons, the flat horizontal top surface and the flat horizontal bottom surface having a channel therein for rotatable receipt of the drive chain assembly, the drive chain assembly including a plurality of rotatable drive rollers connected to the treads and connected to adjacent drive rollers by links to form a continuous drive chain extending completely around the outer surface of each of the pontoons, each tread having an idler roller connected at each end thereof which contacts the surface of the pontoon to support the tread.

Abstract: The in-line roller blade can skate forward, backward, sideward, turn right, turn left and spin to serve as a figure skate. The in-line roller blade figure skate and skateboard comprise a composite belt enwraping around the wheels. The composite belt comprises the resilient belt, string and beads. The self-propelling mechanism can rotate the wheel that the rider can skate without pushing against the ground. These two techniques can be applied to the ice skate to have the sideward skating capability.

Abstract: A baby walker comprised of a movable base, and a seat supported on the movable base by a folding frame, the movable base comprised of a track formed of parallel rollers and endless belt mounted around the parallel rollers, whereby the baby walker is moved forward or backward as the baby supported on the seat pushes the legs against the track.

Abstract: A runner assembly consists of a hollow support providing a track, and a chain link belt revolving in the track, the hollow support consisting of a pair of frame members contoured in mirror symmetry, and which are joined together to provide flanges facing towards each other. The chain link belt is thus guided, and is at least partially encapsulated and protected against contaminants.

Abstract: An improved attachment for an endless track vehicle or crawler, which is attached to shoe plates of the vehicle tracks for preventing the vehicle track running on a paved road from damaging the road surface.

Abstract: A track-type vehicle undercarriage comprising a track frame, a carrier rail mounted on the track frame, a track rail fixedly secured to the track frame underneath thereof, a recoil device mounted on the track frame, a support member fixedly connected to the recoil device and biased forwardly thereby, a front rail rotatably mounted on the support member, a sprocket, and an endless track of linked together track shoes mounted on the carrier rail, front rail, track rail and sprocket.

Abstract: An endless track particularly useful in conjunction with a light-weight track vehicle. The novel track includes endless belt and a plurality of cleats fastened to and spaced about the endless belt. The cleats include rollers to provide the vehicle with agility, ease of operation and reduced turning power.

Abstract: The present invention relates to a track vehicle. The vehicle is comprised of a lightweight frame having a platform or deck portion and first and second track guiding portions. Drive drums are provided, located at one end of each of the track guiding portions. First and second electric motors are connected, via gear reducers, each to one of the drive drums. Idler rollers are located at the other end of each of the track guiding portions. First and second tracks are provided, each encircling and operatively associated with one of the drive drums, one of the track guiding portions and one of the idler drums. Each of the track guiding portions has a bottom portion with each bottom portion having a longitudinally oriented strip of low friction material fastened thereto to provide a sliding surface for each of the tracks when the vehicle is in motion. In another embodiment of the invention the deck portion and track guiding portions are blow-formed from sheet plastics material.

Abstract: A roller for a continuous track on a crawler tractor or the like comprises two sections welded together to define an interior lubrication cavity which communicates by means of lubrication passages to spaces containing bearings and to an exterior lubrication port. Liquid plastic material capable of in situ foaming to form an open cell plastic mass is injected into the cavity and passages wherein it sets into an open cell plastic mass. Subsequently, lubricating oil or grease is injected under pressure through the lubrication port to fill the open cells of the plastic mass for storage and subsequent supply to the bearings through the lubrication passages. The open cell plastic mass also provides a barrier or filter for particles of contaminants disposed in the cavity as a result of welding and other manufacturing steps and prevents circulating of such particles with the lubricant and damage to the bearings and seals.
