Abstract: A refrigerator includes an insulated cabinet having an opening and a first hinge structure. The refrigerator includes a door including a second hinge structure that is movably connected to the first hinge structure. A height adjustment lever operably interconnects the first and second hinge structures.

Abstract: A furniture frame contains a support column, a furniture leg to support the support column, a foot ring, and a fastening device affixing the foot ring to the support column. The fastening device contains a first threaded bushing being non-rotatably connected to the support column and has an external thread, and a second threaded bushing being non-rotatably connected to the foot ring and has an internal thread. The internal thread engages with the external thread. The second threaded bushing is rotatable about the first threaded bushing by at least one revolution such that the second threaded bushing can be axially moved relative to the first threaded bushing. The fastening device has as a locking element which prevents a relative movement between the first and the second threaded bushing in a first operating position and enables relative movement between the first and the second threaded bushing in a second operating position.

Abstract: A generating apparatus for generating electrical power from a horizontal water flow comprises a fixed hub on a support structure and a power wheel arranged for rotation about a vertical axis about the hub. The power wheel includes rotor vanes adapted to cause rotation of the power wheel when the power wheel is subject to a substantially horizontal water flow. One or more generators are provided on the hub to produce electrical power output from rotation of the power wheel relative to the hub. A shroud is rotationally mounted on the hub and arranged to cover at least some of the rotor vanes of the power wheel, so that the water flow is concentrated on the rotor vanes on one side only of the power wheel. A directional controller holds the shroud in a predetermined rotational position relative to the hub dependent on the direction of the water flow.

Abstract: An elevating mechanism for a projection apparatus includes a bottom cover, a resetting element having a first elastic member, a sliding mount, a screw stud sleeve, a screw stud, and a second elastic member. The sliding mount is disposed on a first side of the bottom cover and leans against the resetting element, and the sliding mount has an opening, at least one slot and a thread structure. The screw stud sleeve has a plurality of engaging teeth engaging within the slot. The screw stud has a thread structure and the thread structure of the screw stud meshes with the thread structure of the sliding mount.

Abstract: A movable multi-directional light stand is revealed. The movable multi-directional light stand includes a retractable top support rod that can be received into and connected with a hollow middle support rod. The top support rod is disposed with a mounting slot on a wall, along an axial direction thereof. A sleeve with external threads is disposed around the top of the top support rod and is arranged with a guiding slot corresponding to the mounting slot of the top support rod. A retractable light rod is pivoted to the wall of the top support rod that is disposed with the mounting slot. The retractable light rod is formed by a hollow outer tube and an inner tube that slides in the outer tube and having a hook. The light stand further includes an adjustment nut with threads engaging corresponding external threads of the sleeve so that the adjustment nut can support the outer tube, locate the retractable light rod in the mounting slot and adjust the height of the light.

Abstract: A height adjustable seatpost assembly is provided with first and second tubes, a ratchet mechanism and a drive source. The first and second tubes are telescopically arranged. The ratchet mechanism includes a ratchet tooth structure and a pawl structure. The pawl structure is engaged with the ratchet tooth structure in a lock position. The pawl structure is movably coupled with respect to the ratchet tooth structure in a movable position such that the first and second tubes are movably arranged relative to each other in at least one axial direction of the first and second tubes. The drive source moves the pawl structure between the lock position and the movable position in response to operation of the drive source. The drive source further axially moves the first and second tubes relative to each other in response to operation of the drive source.

Abstract: A force adjustment assembly for use within a telescoping subassembly that includes a first elongated member and a second elongated member that is supported by the first elongated member for sliding motion along an extension axis, the subassembly further including a force equalizer assembly that includes a strand having first and second ends that are supported by the second and first elongated members, respectively, the adjustment assembly comprising a preloader supported by at least one of the first and second elongated members and supporting at least a portion of the strand, the preloader applying a preload force via the strand when the second elongated member is in a fully extended position and an adjuster for adjusting the preload force applied by the preloader.

Abstract: A microphone stand assembly includes an automatically operated anti-rotation arrangement for preventing inadvertent disengagement of the shaft from the base.

Abstract: A chair base includes a rigid base member having a plurality of elongate tubular leg members disposed angularly around and radiating outwardly from a central hub. Each leg member adjacent an outer free end thereof has a hub structure defining a through vertical bore for retaining the pintle of a caster. The hub structure includes coaxially aligned upper and lower sleevelike hub parts which are monolithically and integrally joined to and extruded transversely into the interior of the leg member from the respective top and bottom walls thereof. The pintle-retaining hub structure is formed by a pierce-and-extrude process whereby small pilot openings are initially formed through the respective walls, and the annular wall portion surrounding the respective pilot opening is thereafter transversely extruded to effect forming of the respective hub part. The pierce-and-extrude process for each hub part is, in a preferred process, carried out by a single forming tool.

Abstract: An improved light duty easily adjustable pipe support assembly having a flat base, cushion pad, and free turning adjustment rods. Each adjustment rod has an adjustment knob with friction locking capabilities that permits ease in the turning of the rod while preventing inadvertent turning. A pipe support devise engaged upon the adjustment rods travel vertically up or down along the rods when the knobs are turned. A pipe roller assembly has the capability to compensate for lateral as well as linear movement of the piping system it is intended to support.

Abstract: An adjustable support for a sensor has a first support defining a first end and a second end. A first clamp is fixedly coupled to the first support between the first and second and thereof. The first clamp has an adjustable coupling for selective fixation to a support platform. A second support is adjustably coupled to the first support in a way that supports the second support, facilitates selective movement of the second support relative to the first support in one dimension, and facilitates fixation of the second support relative to the first support. A second clamp is adjustably coupled to the second support so that a sensor fixedly coupled to the second clamp can be moved relative to the second support and fixed thereto by the second clamp.
