A beam having a triangular cross-section, with concave inward side walls forming substantially an equilateral triangle in cross-section, with a convex curved apex at the intersection of each of the three walls, the convex curved apex being formed of a rubber-like material and each having a different radius of curvature to thereby provide a rounded walking surface, each walking surface providing a different degree of difficulty and resulting in a different applied pressure to the foot of the user...

A nonimaging beam combiner and collimator. The nonimaging beam combiner and collimator can include at least two light sources that emit light of the same wavelength through a focus point and a nonimaging element that receives the light of the same wavelength after the focus point and collimates the light at the same wavelength through the atmosphere. The at least two light sources can include fiber light sources, optical fibers, gradient index lenses, fiber lasers or laser diodes. The collimator...

A beam for supporting an load such as a storage rack, platform or the like is provided whereby products in or on the article can be stored safely and displayed. In particular, the present invention includes a beam with a support element having a first and a second end, a continuous base portion having a turned portion positioned between the first and second ends of the support element, a beveled display portion joined to the continuous base portion, and a brace portion joining the display portio...

The invention refers to a beam arrangement for a vehicle. This beam arrangement is designed to extend between and connect two frame side members (2,3) which extend in the longitudinal direction of the vehicle. The beam arrangement includes two side portions (7,8) which extend substantially vertically, and a connecting portion (9) which connects the side portions. The side portions (7,8) converge, as seen from above, in each of the end regions (4,5) of the beam arrangement towards a point situate...

A beam supporter has an upper outer cylinder, a lower outer cylinder, a gearbox connecting these cylinders up an down to each other, and a drive and driven bevels mating one another within the gearbox. A sleeve built in the gear box has an outer periphery integral with the driven bevel, a female threaded inner periphery, and a threaded rod is in mesh with the female thread and extends through the inner periphery. A horizontal shaft of the of the drive bevel protrudes from the gearbox to provide ...

An object of the present invention is to provide a beam source capable of efficiently generating a high-density energy beam having good directivity and a relatively large beam diameter. The beam source of the present invention comprises a discharge tube; a gas inlet for introducing gas into the discharge tube; three electrodes mounted in the discharge tube downstream from the gas inlet, wherein the electrode on the upstream end has a plurality of openings through which the gas can pass, the midd...

A beam isolator which is inserted into at least one end of a tubular beam in a railroad car to minimize the movement of the beam during movement of the railroad car. The beam isolator includes first and second isolating pads, each defining openings. A hinge connects the first and second isolating pads at a first end of said first and second isolating pads. A stopping member is attached to and transversely projects from a second end of the first and second isolating pads. The first and second iso...

A structural beam having a core with a multiplicity of wrappings therearound of shrinkable material, such wrappings being of greater mass than the core and in one embodiment having interlayers of fiber materials between the wrappings of shrinkable material.

A beam compass including a hollow beam, two implement securing units, and a slot communicating with the interior of the beam and extending along at least a portion of the length of the beam and away from the first implement securing unit. At least one of the implements is releasably secured to the beam at a selected location along the slot by means of a second securing unit which includes an interior portion inside the beam and an exterior portion outside the beam. The interior portion and the e...

A trammel head assembly, characterized by the provision of improved locking means for rigidly locking the trammel body to a scale upon which it is slidably mounted. More particularly, the means for locking the trammel body to the triangular scale comprises a yoke member having a transverse portion extending longitudinally completely through said opening, and a pair of parallel leg portions that extend integrally from the ends of said transverse portion within corresponding grooves contained in t...
