93 results about "Transverse orientation" patented technology

Transverse orientation, keeping a fixed angle on a distant source of light for orientation, is a proprioceptive response displayed by some insects such as moths. By maintaining a constant angular relationship to a bright celestial light, such as the moon, they can fly in a straight line. Celestial objects are so far away that, even after travelling great distances, the change in angle between the moth and the light source is negligible; further, the moon will always be in the upper part of the visual field, or on the horizon. When a moth encounters a much closer artificial light and uses it for navigation, the angle changes noticeably after only a short distance, in addition to being often below the horizon. The moth instinctively attempts to correct by turning toward the light, thereby causing airborne moths to come plummeting downward, and resulting in a spiral flight path that gets closer and closer to the light source.

Sports equipment holding device

A portable holder for supporting a ski, snowboard, bicycle and firearm during cleaning, maintenance, adjustment, sighting and repair operations at a work station, the holder being adapted to support a portion of the ski, snowboard, bicycle and firearm, the portable holder comprising: a base section adapted to be fixed to the work station in a substantially upright position; a threaded rod mounted to the base section in a substantially vertical orientation; and, one of a support bead and a vise assembly affixed to the upper portion of the threaded rod; wherein the base section contains a substantially vertically orientated threaded aperture allowing the threaded rod to be rotated about its longitudinal axis into the threaded aperture of the base section to permit both mounting of the threaded rod to the base section and height adjustment of the threaded rod relative to the base section; the support head having a base and at least one flange extending upwardly from the base to receive a support tongue of one of a ski and snowboard support, a bicycle bottom bracket shell support, and a gun barrel cradle and means for pivotally connecting and locking at least one flange and the support tongue; at least one flange of the support head having a substantially horizontal aperture formed therein for receiving a bicycle axle in a substantially transverse orientation to the support head.

Spherical flue element equivalent model thermotechnical waterpower experimental apparatus

ActiveCN102855802AReflect thermal hydraulic characteristicsRealize electric heatingEducational modelsThermal expansionEngineering
The invention discloses a spherical flue element equivalent model thermotechnical waterpower experimental apparatus comprising a pressure-bearing component, an electric heating component, an insulation component, a seal component, a pressure measurement component and the like, and field assembly and disassembly can be realized between the components. According to the spherical flue element equivalent model thermotechnical waterpower experimental apparatus, a banded fin thin rod bundle electric element is taken as an equivalent model structure of the spherical flue element, electrical heating method is realized, single-phase water flow and heat transfer experiment can be developed, and thermal-hydraulics of the spherical flue element can be reflected. The pressure measurement component can be assembled and disassembled on spot, consumables such as an O-shaped seal ring and a lead pressure pipe are convenient to replace, thereby reducing loss and cost. A grid spacer plays a role in transverse orientation for the banded fin thin rod bundle electric element, and a single-cone structure of the grid spacer can guide a plurality of the banded fin thin rod bundles to assemble, thereby reducing the difficulty of assembling and improving the efficiency of assembling. Copper braid is adopted to connect a lower conducting element and a lower conductive contact to realize flexible connection, so that the problem caused by electric component thermal expansion is effectively solved.
