A musical comb for a striking mechanism of a timepiece includes several tines connected to a heel for securing the comb inside the timepiece. The musical comb further includes grooves in the heel each extending into the extension of each space between the adjacent tines in order to eliminate any dissonance during actuation of the tines.

A resonant member for a striking mechanism of a watch or of a music box includes at least one resonant part, such as one or more gongs, arranged to vibrate and resonate once activated, and an attachment part. The resonant part and/or the attachment part is made from an alloy of tungsten or tantalum or rhodium or hafnium with more than 51% of tungsten or tantalum or rhodium or hafnium in the alloy.

A resonant member for a striking mechanism of a watch or of a music box includes at least one resonant part, such as one or more gongs, arranged to vibrate and resonate once activated, and an attachment part. The resonant part and/or the attachment part is made from an alloy of palladium or platinum with more than 51% of palladium or platinum in the alloy.

Systems and methods for dewatering slurries having relatively high solids content such as earthen slurries are disclosed. In some embodiments, one or more transducer devices configured for acoustic spectroscopy and/or electroacoustic spectroscopy are used to determine a parameter related to the particle size distribution (e.g., specific surfaced area) and/or zeta potential of the slurry.

The resonant member for a striking mechanism of a watch or of a music box includes at least one resonant part, such as one or more gongs, arranged to vibrate and resonate once activated, and an attachment part. The resonant part is made from a copper alloy with more than 70% of copper in the alloy.

A metallophone structure configured for permanent installation in an outdoor environment is provided. The metallophone structure comprises a mounting structure. The metallophone structure also comprises a set of tone producing devices each coupled to the mounting structure by a fastener, wherein each tone producing device is configured to, when actuated, produce a sound frequency. The tone producing device is coupled in a location, by the fastener, as to reduce the effect on the quality of sound produced. The metallophone structure also comprises a mallet cradle configured to receive a mallet. The mallet is configured to actuate one of the tone producing devices. The metallophone structure is configured to be weather resistant such that each tone producing device still produces the sound frequency after an outdoor exposure period.
