Abstract: Embodiments disclosed herein relate to superabrasive compacts having a metallic member disposed between a superabrasive body and a substrate; and drill bits and methods of making the same.

Abstract: A wind turbine yaw brake apparatus includes a circular rotation support base having an inner and an outer cylinder wall. The circular rotation support base is mounted to a top face of a wind turbine tower and a nacelle such that the nacelle can rotate relative to the wind turbine tower. A plurality of brake lining elements are removably mounted to the circular rotation support base. A disc brake unit acts upon the brake aligning elements.

Abstract: A novel truss track assembly for use in transporting passenger vehicles provides two sets of tracks for supporting two passenger vehicles concurrently. The truss track assembly includes four running rails for mounting passenger vehicles and a central support rail. A series of frame elements are periodically secured to the running rails and the central support rail to support and maintain the parallel relationship of the running rails and the central support rail. The truss track assembly may be “split” into two individual truss track assemblies wherein the individual truss track assemblies each accommodate a passenger vehicle or a train of passenger vehicles. The present invention further provides a novel side-mount vehicle suitable for mounting of the present invention on the truss track assembly.

Abstract: An apparatus which measures the deflection of a single or double reed of a woodwind musical instrument. A strain measuring transducer affixed to the reed measures the amount of pressure applied by the players lip or lips to said reed. In the preferred embodiment, the signal indicative of the deflection is delivered to the bridge completion circuit. This circuit is amplified by the high gain amplifier to a level that can be read by the adjustable peak level indicator or viewed on a readout meter. A method whereby musicians are provided with an indication of lip pressure for comparison and analysis. The signal can also be viewed on a time based voltage recorder or spectrum analyzer for quantitative lip pressure effects as well as timbre characteristics of different mouthpieces, reeds, ligatures and instruments.
