Abstract: A snowboard boot (200) includes an upper boot (204) secured to an outsole (206). The boot upper includes a vamp opening (208) that is closed by a tongue (210) and a selectively securable vamp fastener (216). The tongue (210) carries a pocket (218) on a lower end (212) thereof, and first and second snap fasteners (222) on an upper end (214) thereof. A semi-rigid tongue stiffener (202) can be selectively secured to an anterior side of the tongue (210) utilizing the pocket and snap fasteners to selectively increase the stiffness of the boot and resistance to forward flexure by a predetermined degree.

Abstract: An interface adjustment mechanism 100 is provided that includes a frame member 102 and fore and aft adjustable spacer holding members 104, 106, and is disposed within the outsole of the snowboard boot 10. The interface adjustment mechanism 100 also includes a plurality of interface adjustment assemblies 160. Each interface adjustment assembly 160 includes a base member 170 having a threaded aperture and an adjustment member or spacer 172 having a threaded portion threadably engageable with the threaded aperture of the base member so that the spacer 172 can be adjustable relative to the base member 170. When incorporated into the snowboard boot 10, the interface adjustment mechanism 100 provides the rider with an adjustable spacer/dampening system that can eliminate slop and provide dampening and shock absorption between the snowboard boot 10 and the snowboard binding 30. Eliminating slop and providing dampening and shock absorption provides the rider with improved control, force transmission, and feel.

Abstract: An embodiment of a snowboard boot with removable upper support includes a sole portion that cooperatively with an upwardly extending boot upper provides a volume for receiving a user's foot. The boot upper has a high back portion that includes an interior pocket adapted to receive a generally Y-shaped stiffening insert. The pocket is provided at the back of the upper, by attaching a back panel to the upper, the back panel having a front panel attached to the front side, thereby forming a pocket. Slots are provided at the top comers of the back panel that can slidably engage the upper tabs of the insert, thereby locking the insert in place.

Abstract: The present invention is directed to a strap assembly (150) for a sports boot (100), that includes a first strap (151) pivotally connected at one end to the boot heel portion (130), and a second strap (161) pivotally connected to the opposite side of the heel portion. A clasp (159) is provided that allows the first strap to be adjustably connected to the second strap. One or both of the straps are attached to the heel portion with a slider mechanism (180) that allows the proximal ends of the straps to be selectively adjusted. The slider mechanism includes a slider plate (181) attached to the boot upper (120) having a medial channel (184) with an elongate slot (186). A nut plate (200) is slidably disposed in the medial channel, and a screw (210) connects the strap to the nut plate.

Abstract: A step-in binding system (20) for securing a boot (24) to a snowboard (22). The boot includes a sole defining a toe end, a heel end, and a binding attachment surfaces (46 and 50). The boot also has an elongate, substantially U-shaped highback (28) mounted to the exterior of the boot in the calf area thereof and extending from the ankle area to the top of the boot. The step-in binding system includes a toe and heel binding (62 and 64) attached to the snowboard for receiving and securing the boot to the snowboard. The step-in binding system also includes a lever arm (66) attached to the heel binding for selectively releasing the boot from the binding. A lean support member (68) is fastened near the rearward end of the binding for engagement with a stopper block (29) secured to the highback to define a minimum forward lean angle of the boot and to limit the aft flexure of the ankle support portion of the boot when the boot is received within the binding.

Abstract: A method of coacting a fluid with a media, such as granular particles. The media is moved to an upper portion in an upright media container, and held there during a treatment cycle in which the fluid is coacted with the media. When the media requires regeneration, the media is allowed to fall to a lower portion of the media container where a regeneration fluid is passed through the media.

Abstract: A radial flow fluidized unit (RFFU) (250) employing non-bonded media particles (56) for removing impurities from an influent, that can be backwashed and/or regenerated by fluidizing the media particles (56) to free the impurities therefrom. During a fluidization operation a fluid applies a drag force on a section of the media particles (56) within a volume of the unit where the media co-acts with the influent: (Volume 1). The drag force transports the media particles (56) into a second volume (Volume 2) for fluidization. Under normal conditions the top portion of the unit contains the packed media (56) where the influent co-acts with the media (56) (Volume 1). The RFFU (250) can also operate in the reverse where the bottom or opposite end contains the packed media (56) for co-acting with the influent.

Abstract: The present invention is an automatic filter cleaning system which includes a solvent dewaxing filter which removes wax from a wax mix slurry and provides a filtrate. Status control apparatus is connected to the filter for affecting the operational status of the filter. Drain apparatus responsive to a control signal controls draining of the filter. Cleaning apparatus is also connected to the filter. A control network connected to the status apparatus, the draining apparatus and the cleaning apparatus controls those apparatus in a manner so as to allow selective changing of the status of the filter from an operational state to a down state to automatically drain the filter and clean the filter while the filter is in the down state.

Abstract: A helical-element antenna as part of a communication system is mechanically steered with reference to an azimuth axis and an elevation axis within a positioning envelope greater than hemispherical. The system for mechanically steering the helical antenna includes a supporting frame having an azimuth member with a longitudinal axis coinciding with the azimuth axis around which the antenna rotates. Further, the supporting frame includes an elevation member that is integral with the azimuth member and has a longitudinal axis displaced from the azimuth axis. An interface fitting rotatably mounts the antenna to the elevation member. The supporting frame is rotatably mounted to a pedestal base that has a plane perpendicular to the azimuth axis. To position the antenna about the azimuth axis, an azimuth steering unit is energized to rotate the supporting frame 360 degrees around the azimuth axis.

Abstract: A solar power satellite (30) includes a truss structure (32) having a plurality of independently controlled solar power modules (34) mounted to one face of the truss structure. The solar power satellite is constructed in orbit by first forming and then assemblying component beam members (50, 52) to the truss structure. The solar power modules (34) are constructed on a fabrication and assembly station (36) movably attached to the truss structure and are then attached to the truss structure. The solar power modules (34) include a primary reflector (200) having a substantially parabolic curvature in cross section. A collector-radiator (202) is mounted on the primary axis of the primary reflector. The cross-sectional configuration of the collector-radiator (202) approximates a flattened inverted S-shape whereon the radius of curvature decreases as the curve approaches both its center and its end furthermost from the primary reflector (200).
