Abstract: Rail assemblies on either side of a shelf each include a rail reciprocated to a slide adjustable from a rail-locking position to a post-locking position. The slide is configured to restrain the rail from reciprocating longitudinally relative to the slide, when the slide occupies a rail-locking position and the rail occupies a stowage position relative to the slide. The slide is configured to enable the rail to reciprocate longitudinally relative to the slide and to releasably secure a rack post, when the slide occupies the post-locking position.

Abstract: A load-conveying and transport apparatus includes a first frame, a conveyor carried by the first frame, and a second frame mounted to the first frame for movement between lowered and raised positions relative to the conveyor. The second frame lies below the conveyor, when the second frame is in the lowered position relative to the conveyor. The second frame lies proud of the conveyor, when the second frame is in the raised position relative to the conveyor. The conveyor is for conveying a load placed thereon without interference from the second frame, when the second frame is in the lowered position relative to the conveyor. The second frame is for supporting the load placed thereon above the conveyor for disabling the conveyor from conveying the load, when the second frame is in the raised position.

Abstract: A lift device includes a lifting mast having a top, and a drive assembly for moving the lifting mast in lifting and lowering directions. A head is positioned above and over the top of the lifting mast, and is mounted to the lifting mast for displacement between a neutral position and a safe position with respect to the lifting mast in response to the head contact encountering an object above the top of the lifting mast and the head. The drive assembly is enabled for moving of the lifting mast in the lifting and lowering directions in the neutral position of the head, the drive assembly is enabled for moving the lifting mast in the lowering direction in the safe position of the head, and the drive assembly is disabled for moving the lifting mast in the lifting direction in the safe position of the head.

Abstract: A lift apparatus includes a lift device operable for raising and lowering a first platform, a base releasably connected atop the first platform, a second platform mounted to the base for tiltable movement between a first position and a second position relative to the first platform, the second position of the second platform being tilted relative to the first position of the second platform, and a retention assembly coupled between the base and the second platform for selectively tilting the second platform from the first position to the second position, and selectively retaining the second platform in the first position and in the second position.

Abstract: A bucket includes a first volume defined by a continuous primary sidewall extending from a periphery of a first bottom to a primary rim and has a flattened portion extending from the periphery of the first bottom to a subjacent portion of the primary rim. An inner surface of the flattened portion of the primary sidewall is textured to form a paint roller grid. A second volume is defined by a continuous secondary sidewall extending from a periphery of a second bottom to a secondary rim and has a flattened portion extending from the periphery of the second bottom to a subjacent portion of the secondary rim adjacent the subjacent portion of the primary rim. An edge couples the subjacent portion of the secondary rim and the subjacent portion of the primary rim.

Abstract: A device for lifting, lowering, and mounting rack-mounted equipment has an “L” shape frame. A platform is vertically movable in a vertical member of the “L” shaped frame. The platform has a horizontally movable top surface. A plurality of wheels is coupled to a bottom surface of the “L” shaped frame. A lifting mechanism is coupled to the platform for moving the platform vertically in the vertical member of the “L” shaped frame. A stabilizer unit is coupled to the bottom surface of the “L” shaped frame.

Abstract: An apparatus and method for cooling air that utilizes a removable reservoir that may be filled with a consumable beverage or other cooled liquid or solid material. The bottom of the reservoir is made of a thermally conductive material that is placed within an air duct within a base unit that has a battery powered fan capable of drawing in warm air from outside of the base unit and cooling it by passing it over the thermally conductive material in a turbulent fashion and expelling it back into the surrounding environment. An expandable hose may also be included to direct the airflow in a desired direction or location. The unit may also include an alternative path for airflow such that the airflow may be heated. The unit may also be secured to an open air vehicle such as a golf cart to provide cooled or heated air for golf course patrons.

Abstract: A celestial tracking apparatus (20) has a support (26), a tracking assembly (28) coupled to the support (26) by an azimuth pivot (36), a collector assembly (30) coupled to the tracking assembly (28) by an elevation pivot (38), a wind-speed sensor (172), and a controller (150) coupled to the azimuth and elevation pivots (36,38) and configured to cause the collector assembly (30) to assume a wind-stow position (66) when the sensor (172) detects a wind having a speed greater than a predetermined speed, upon failure of a component of the apparatus (20), or upon receipt of a wind-stow command. The collector assembly (30) has a solar collector (22) with a substantially flat surface (24), a center of gravity (52), and a target axis (54) substantially perpendicular to the substantially flat surface (24) and passing through the center of gravity (52).

Abstract: A pair of struts are frictionally and mechanically disengageably engaged with corresponding ones of opposed uprights of the base of an ankle brace walker to provide rigidity to an enveloped foot and ankle. The base includes a plurality of longitudinally aligned laterally offset flanges intermediate laterally aligned flanges, all of which flanges are disposed intermediate the sole and the foot bed of the base to provide rigidity for the foot and with sufficient strength to permit walking without danger of breakage of the base with resulting injury to a user. Cushioning means and strap means retain the foot and ankle comfortably but firmly within the ankle brace walker.
