摘要： A method for measuring dynamic hardness of elastic materials is applied particularly to determining the state of tonal quality for a piano hammer. The method includes selecting a piano hammer of predetermined type from a set of piano hammers, causing the selected piano hammer to strike against an impact surface having the form of a piano string or string grouping appropriate to a piano hammer of the predetermined type, measuring one or more elements of force and motion of the piano hammer striking the impact surface, e.g. force, determining, e.g., the cut-off frequency of the power spectrum for the selected piano hammer striking upon the impact surface, and comparing the determined cut-off frequency of the power spectrum for the selected piano hammer against a predetermined range of cut-off frequencies of power spectrum acceptable for piano hammer of the predetermined type. An apparatus for testing is also described.

摘要： A nozzle seal for restricting pneumatic leakage from the nozzle hole of a pneumatic hammer having a tool shank movable therein, comprising, a bushing member and a retaining member axially aligned in the nozzle hole of the pneumatic hammer with a seal member therebetween. Bores are provided through the bushing member, retainer member and seal member for accepting the tool shank with the seal member having a bore closely fit around the tool shank to prevent a leakage of air from the interior of the hammer through the nozzle hole. The bushing member is press-fit and firmly held in the nozzle hole while the retainer member is slip-fit into the hole to facilitate its removal and access to the seal member. The bores may be polygonal, circular or oval to accept tool shanks of corresponding cross-sectional shapes. An O-ring may be provided on the retainer member for establishing a hermetic seal between the retainer member and the nozzle housing and a pin may be provided on the retainer member extending through an aperture in the seal member to establish a proper orientation between the bores of the retainer and bushing members and the bore of the seal member.

摘要： Sudden changes in arc current are slowed to mitigate the resulting noise. A sensor detects large decreases in current during initial stages of arc quench and actuate circuits to maintain ionization and current flow to avoid sharp final drop that causes loud noise impulse. Ionization can be maintained by supplying RF energy at appropriate frequency to the arc electrodes and/or by increasing the arc voltage. The sophisticated control algorithm is implemented utilizing an inexpensive microprocessor to exert proper control of arc sustaining parameters to mitigate arc quenching impulse noise.

摘要： A technique for reducing noise generated by transverse vibrations in elongated members comprises the application of a friction element on a surface of the member. The friction element is forced against one or more surfaces of the member by a selected normal force and is provided in a vicinity of maximum distortion of the member when the member undergoes vibrations. A differential movement between the inner surface of the friction element and the outer surface of the member causes heat to be generated which dissipates the energy of such transverse vibrations.

摘要： A device for treating flowing working gases in order to reduce their operational noises and in most instances also to increase their operating efficiency comprises a flowing working gas operating device which has a discharge conduit with at least one discharge opening for the outflow of the working gas. A check valve is associated with the discharge and includes an elastic valve member movable to close the opening when the flow thereof decreases to a predetermined amount for example as determined by the reduction of pressure of the gases so as to prevent any back flow into the conduit which is likely to produce noise. The elastic member may comprise an ordinary rubber band which is preferably held in position by a guide member so that when the pressure of the working gas is sufficient the gases will flow out of the discharge conduit and will be directed through one or more chambers so as to cause the gas to flow into a whirling vortex flow and preferably in a substantially annular path so as to order the gases and to thereby increase their efficiency of operation.

摘要： A reduced operating noise nozzle for a cutting device using at least one electrode and an electric arc to cut material of a workpiece, comprises, a nose end piece disposed around the electrode which has an outer surface tapered from an outer relatively wide diameter end inwardly toward a smaller diameter end which faces the workpiece to be cut. Compressed air is directed in a substantially annular flow path along the tapered surface of the nose piece from the wide diameter end toward the smaller diameter end thereof. Noise which would have emanated from the nozzle, especially when the material of the workpiece which is melted by the arc is blown away to effect the cutting operation, will be greatly reduced.
