The mechanism for producing the harmonic sounds of a grand piano is a mechanical musical accessory which exploits the physical phenomenon of harmonic, or multiple, sounds of a fundamental. The mechanism is applicable to all the strings of grand pianos and can be used to select and prepare in advance any one of the sounds of the harmonic sequence of each note. By means of this accessory, the piano ...

A class of bridged or unbridged metallocene compounds is disclosed, wherein the cyclopentadienyl ligands have two or four adjacent substituents forming one or two alkylenic cycles of from 4 to 8 carbon atoms. These metallocenes are useful as catalyst components for the polymerization of olefins, particularly for the (co)polymerization of ethylene and for the polymerization of propylene.

The invention regards a system for accelerating the rotation of sacks on palletising machines, consisting of the fact that, before the sack reaches the rotation device of a known type, a first partial rotation of 45 degree is imparted by appropriate means. This is obtained, for example, by pushing the sack laterally during its passage by means of a pusher which, at the appropriate moment, strike...
