Abstract: A caster wheel assembly includes at least one hub that has an annularly dished concave region disposed between a pair of cylindrical lips about its outer periphery. An elastomeric tread has a convex inner periphery that seats in the concave region of the hub. The interface between the hub and tread is parabolic in cross-section to manage load-inducted stresses in the tread. The parabolic cross-section is defined by the equation y=A*x2, where A is between 1.5 and 4. A cylindrical lip/pad interface is established between hub and tread on opposite sides of the parabolic interface to accommodate high load situations. A bearing is supported in the hub, and a bushing inside the bearing. An axle shaft passing through the bushing attaches the hub and tread to a support bracket for use in a wide variety of industrial applications.

Abstract: The invention discloses an LED light fixture, which comprises a lamp body and a lamp handle connected therewith, wherein the lamp body adopts an AC (Alternating Current) LED as a light source. As the LED light fixture does not need a power supply, the light fixture has the advantages of being small, having a simple structure and saving materials; as a plurality of small planes are used for forming a complete multi-stage sagittal reflecting surface, the light fixture has higher reflection efficiency; as a gland strip and a shielding mechanism are adopted, the reverse side of the product has a complete structure and is lightproof; as non-through screwed connection holes are formed at positions of the lamp body, at which the lamp body is connected with the lamp handle, the light fixture has superior sealability and watertightness.

Abstract: A shelving assembly including a frame including a plurality of support columns. A shelf unit includes a plurality of sides disposed inside the frame. A gear assembly is disposed adjacent to one of the plurality of sides of the shelf unit. The gear assembly includes a drive shaft, a translational shaft and a translational gear disposed on a distal end of the translational shaft. A vertically-extending toothed rack is positioned on the frame. The vertically-extending toothed rack is operably engaged with the translational gear such that rotation of the drive shaft causes rotation of the translational shaft and rotation of the translational gear, which results in vertical translation of the shelf unit.

Abstract: The present invention relates to a polysaccharide extract derived from a mushroom of the Lentinus genus and also to the method for preparing such an extract. This polysaccharide-rich extract can be used as a nutraceutical, cosmetic or pharmaceutical preparation.

Abstract: A caster has a ring-shaped main body, two ring-shaped wheels provided on both side end parts of the main body and two ring-shaped holders by which the two ring-shaped wheels are rotatably fitted on the main body. Each of the wheels has a first sliding face on an inner side of an inner circumferential part and a second sliding face on an outer side thereof. A first dry bearing is provided between an outer circumferential face of a ring-shaped flange provided on each of the both side end parts of the main body and the first sliding face, a second dry bearing is provided between an outer circumferential face of a ring-shaped flange provided on an outer end part of each of the holders and the second sliding face. The caster provides a high mechanical stability, durability, impact resistance and heat resistance.

Abstract: A caster includes a base carrying a rotation shaft and forming a pivotal joint seat. Wheels are rotatably mounted to the rotation shaft. Each wheel has an inside surface that is recessed to form an inner rim. A brake arm has a first end rotatably coupled to the pivotal joint seat and a second end forming a brake pawl extending into the inner rims of the wheels. A spring is arranged between the brake arm and the base so that the spring normally biases the brake pawl to depress against the inner rims of the wheels to brake the wheels. A release knob is rotatably mounted to the base and forms a cam section positionable against the brake arm. The cam section, when rotated by the release knob, drives the brake arm backward to release the brake pawl from the wheels, allowing the wheels to freely rotate.
