Abstract: In a hydraulic mount the use of multiple primary orifices with unequal area reduces the effects of rapid transitions in dynamic rigidity and the amplitude of impulsive vibration generated thereby. This invention's reduced impulsive vibration has lead to the substantial elimination of mode transition related noise in associated vehicle structures in the 200 Hz to 500 Hz range.

Abstract: An apparatus to assist the musical instruction of a student including one or more tone sources (e.g. flute, human voice, violin) playing monophonically as inputs, means to quantify aural parameters of pitch, amplitude, duration, and timbre of inputs, means to visually store and represent temporal history of said, means to store and playback audio signal of inputs, and means to arrive at and display musical related pitches. A digital waveform analyzer is used to control a tunable low-pass filter in the pitch tracker and preform spectral estimation of timbre. Also, a digital version is described. Pre-recorded music instruction and a karaoke player are used as examples of reference tone sources. Visual representation of aural parameters can be provided as video output.

Abstract: The present invention provides a pressure-sensitive adhesive composition and a method for producing the same. The pressure-sensitive adhesive composition is produced by the combination of at least one free-radically photopolymerizable monomer and at least one cationically polymerizable monomer and a suitable photoinitiation system consisting of at least one salt of a cationic organometallic complex, an optional additional free-radical initiator and the application of sufficient energy to photopolymerize same.

Abstract: A music re-performance system allows a plurality of untrained instrumentalist to play pre-stored music using traditional playing techniques along with an automatic accompaniment at a tempo controlled by a selected-instrumentalist. Instrumentalist's gestures start and stop pre-stored score notes and temporal restrictions limit gestural timing errors. Expression parameters, including volume, timbre, and vibrato, are selectively updated, allowing editing of music sound files. A finger manipulation and energy driver controller model, including transducers and signal processing, accommodates wind and string instruments. Temporal masking prevents substantially concurrent finger and energy gestures, intended as simultaneous, from producing multiple false gestures.

Abstract: The present invention provides a pressure-sensitive adhesive composition and a method for producing the same. The pressure-sensitive adhesive composition is produced by the combination of at least one free-radically photopolymerizable monomer and at least one set of polyurethane precursors, and a suitable photoinitiation system consisting of at least one salt of a cationic organometallic complex, an additional free-radical photo initiator and the application of sufficient energy to photopolymerize same by sequential exposure to visible electromagnetic radiation and then to ultraviolet electromagnetic radiation.

Abstract: Composition comprising (a) susceptors having the capability of absorbing microwave energy, said susceptors comprising a particulate substrate substantially non-reflective of microwave energy and a coating capable of absorbing microwave energy, and (b) a matrix substantially non-reflective of microwave energy. Susceptors are typically particles having a thin-film coating thereon. The matrix typically comprises polymeric or ceramic materials that are stable at temperatures conventionally used in microwave cooking. The composition allows reuse of the susceptors, eliminates decline in heating rate, eliminates arcing, allows the heating rate to be controlled, allows overheating to be controlled, and allows formation of microwave heatable composite materials having very low metal content.

Abstract: Apparatus for producing a metal powder includes a cooled hearth structure in which a metallic alloy is melted and a heat source above the hearth positioned to heat the melt in the hearth. The cooling of the hearth causes a protective hearth skull to form between the melt and the hearth itself. The hearth is placed within an environmental control chamber. A supply structure provides a continuous supply of the metallic alloy to the hearth structure from the exterior of the chamber. A metal powder producer is positioned to receive molten metal from the hearth, and a continuous stream of the molten alloy from the hearth is transferred to the metal powder producer. The transfer is accomplished by tipping the hearth or by teeming through an opening in the bottom of the hearth. The hearth structure can utilize two individual hearths, controllably arranged so that molten metal is drawn from one hearth while the other is recharged.
