This relates to a bicycle saddle of the type that presents two identical portions (1, 1′) longitudinally symmetrical. Thanks to its special conformation, said saddle permits the cyclist to avoid the occurrence of pathologies normally caused by the use of a racing saddle of commonly known types, eliminating the crushing of the vascular structure of the perineum, as well as the testicles of male cyclists and the clitoris of female cyclists. The special geometry permits a pedaling action without causing friction of the thigh muscles, in particular the delicate and adducent muscles.

A self-piercing rivet of a special rivet geometry is described, which in particular is suitable for joining high strength steel sheets, but can also be used for other metal sheets. The self-piercing rivet is in particular characterized by a special underhead geometry as well as a special geometry of the rivet foot (cutting region). Thus the self-piercing rivet has an underhead chamfer which with a radial plane of the self-piercing rivet encloses an angle of 20°+5°/−5° and merges tangentially into the cylindrical outer surface of the rivet shank via a radius. In the region of the rivet foot the self-piercing rivet has a plane shank face, which extends essentially at a right angle to the rivet axis and which merges “smoothly” into the cylindrical inner surface via a shank inner surface and a radius. In comparison to conventional self-piercing rivets the special rivet geometry enables lower joining forces and tensile forces in the joining operation, an optimized load bearing performance and an optimum joint quality of the self-piercing rivet joint as well as minimum gap formation between the rivet and the metal sheet.

A rear frame of a trailer has an elongated horizontal sill having a closed cross-section which is rigid in bending and in torsion. The elongated horizontal sill is formed of a fantail and a base plate attached to an underside of the fantail. The base plate has front and rear sections that are not notched as notching of the sill can weaken it. The front section is horizontal and the rear section is angled upwardly relative to the horizontal front section at a predetermined angle of approximately 22 degrees. The angling of the base plate provides a specialized geometry for accommodating a tuck-under lift gate. The sill also has minimal vertical dimensions to aid in the non-interference with legs of the tuck-under lift gate.

The invention belongs to the field of optical measurement and relates to an optical doubling frequency laser interference measurement method for the displacement of a special geometric point. The method comprises the following steps: symmetrically placing two pyramid prisms on two sides of a special geometric point on a measured object; accurately obtaining the displacement of a central point by utilizing the displacement sum of two points; and dividing laser output light into measurement light and reference light by utilizing a polarization light splitter, wherein the measurement light respectively passes through the two pyramid prisms and returns twice in each pyramid prism and the measurement light moves for 8 Delta if a measured point moves for one Delta so that the optical octuple frequency of interference measurement is realized and the measurement accuracy is improved. Because the measurement light returns along the prior path in the pyramid prisms, even if the measured object moves in a plane vertical to a motion direction according to the characteristics of the pyramid prisms, the measurement accuracy of the motion direction is not influenced so that the method can be more widely applied. The invention can be applied to the measurement of non-guide rail movement and other complicated movements with more measured object freedom.

We disclose a device for the production of hydrogen from water using heat. The device employs thermal water splitting and works essentially without electricity. It is based on the concept of a membrane reactor with two kinds of membranes allowing the separation of hydrogen and oxygen simultaneously in stoichiometric quantities from the reactor volume. The device has a special geometry resulting in a temperature distribution inside the reaction chamber to accommodate the use of hydrogen selective membranes. The device will help to reduce the need for hydrogen transport and storage as it will be rather compact for on-site use in households, small factories or gas stations. The use of the device in mobile applications is conceivable. The heat source of the device as described is combustion of a hydrocarbon using porous burner technology; however the device can be modified to exploit any other heat source, especially solar radiation.

Various embodiments for magnetic detent assemblies provide for detent devices with improved performance and manufacturability. In one embodiment, magnetic detent assemblies provide for custom detent positions and custom force profiles by including a pair of unitary magnetic components each having a special geometry. In an embodiment, the changing area of overlap (and hence magnetic flux) between the magnetic components can give rise to the custom detent positions and custom force profiles. In a specific embodiment, the magnetic components can comprise an N-point star shaped geometry, where the number and distribution of the start wings can be varied to define customized detent positions and the contour of the star wings can be varied to create customized force profiles. In other embodiments, devices such as laptop computers and docking stations for handheld electronic devices can implement multi-position detent hinges with the magnetic detent assemblies.

A novel gasket includes at least one gripping element embedded in an annular member for forming a seal between two tubulars. For tubulars having socket and spigot ends, the gripping element includes teeth for gripping an outer surface of the spigot end and a blunt tooth for contacting a front wall of the socket end. The blunt tooth rolls along the front wall during relative movement between the tubulars and can include a contacting face of a specialized geometry to adjust contact dynamics and/or roughened surfaces to increase the frictional contact between the blunt tooth and the front wall. The embedded element can also include at least four teeth arranged such that no more than two teeth normally grip the outer surface of the spigot end. One or more teeth can also include a transverse groove to enhance penetration into the outer surface of the spigot end.
