Abstract: A group of water-soluble salophene-lanthanide complexes and other salophene-metal complexes are useful for purposes including: (i) detecting neutral carbohydrates at physiologically-relevant pH, (ii) the selective detection of gangliosides, and (iii) the selective detection of lysophosphatidic acid (LPA) in the presence of phosphatidic acid. The selective detection of LPA is useful in diagnosing ovarian and other cancers.

Abstract: The present invention provides a throttle position sensor for a motorcycle including a handlebar having an end. The throttle position sensor includes a rotor having a first end and a second end. The rotor is positioned within the handlebar and rotated relative to the handlebar. The second end is closer than the first end to the end of the handlebar. The throttle position sensor also includes a sensor operable to detect rotation of the rotor relative to the handlebar and generate a signal corresponding to the rotation of the rotor relative to the handlebar. The throttle position sensor further includes at least one electrical conduit passing into the rotor from the first end. The at least one electrical conduit is routed through the rotor and is accessible from the second end of the rotor.

Abstract: An inexpensive, stereoselective synthesis for nootkatone, tetrahydronootkatone, and their derivatives is disclosed. The starting materials used in the synthesis are inexpensive. The principal starting material, (?)-?-Pinene, is on the GRAS list (generally recognized as safe).

Abstract: Rotary power slips mounted in the rotary table of an earth drilling rig and having slips for gripping and releasing pipe in the rotary table. The air transfer ring has concentric grooves in the upper surface. An annular seal ring is secured to the body of the rotary power slips and has a pair of air passageways. The air passageways lead to secondary fluid conduits in the body, which, in turn, lead to each end of the pneumatic cylinders to raise and lower the slips. Expansive rings are secured to the surface of the air transfer ring by mounting the edges of the rings into the grooves in the air transfer ring. When air pressure is applied through one of the primary fluid conduits, one of the expansive rings expands and cooperates with the lower surface of the seal ring to form an expansive fluid duct. The air pressure flows through a perforation in the expansive ring into the expansive fluid duct, and then through the air passageway and the secondary fluid conduit to the pneumatic cylinders.
