  • Sound generator
    Patent number: 5910648
    Abstract: In a sound generator of the type having a motor powered piston (7-9) limiting a chamber (18) connected to a resonance tube (16) and which is adapted to generate sound waves for cleaning heat exchange surfaces, the piston (7-9) is according the invention provided with two axially spaced piston membranes (8, 9) and a device (19) for establishing a vacuum between the two membranes (8, 9) and thus ensuring only tensile stresses in membranes (8, 9) thereby increasing their life time.

  • Motor powered sound emitter
    Patent number: 4805732
    Abstract: In a sound emitter including an emitting piston powered by a three phase asynchronous electric motor, the torque curve of the motor may be adjusted to suit any temperature, causing variations in the emitted resonance frequency by using a motor having its maximum torque at less than half the maximum speed. This may be done by using an alloy of silicon and aluminum in the rotor winding.
