    摘要: A carpet stain removal product and process are disclosed. The product includes a liquid cleaning composition (18) which contains water, an organic solvent and a surfactant, an absorbent stain receiver, and a sonic or ultrasonic wave generating source (10) for imparting sonic or ultrasonic waves onto stains (14) on textiles (16). The sonic or ultrasonic wave source is, for example, a hand-held, pen-shaped device with a directed point to focus the sonic or ultrasonic waves at the stain to be removed.

    摘要: A screening system having a resiliently mounted frame with a screen extending thereacross. The frame is vibrated by a low frequency vibratory drive using eccentric weights. About the peripheral frame of the screen, a high frequency drive or drives is employed to vibrate the screen in the range of 20,000 Hz. The high frequency vibration is generated at the peripheral frame about the screen. The screen is responsive to the high frequency vibrations in a plate-like manner rather than as a membrane.

    摘要: An electric oscillating tool, having particular but not necessarily exclusive utility as an electric toothbrush, for driving a brush head assembly or end effector with a resonant mechanism at high frequencies. The electric toothbrush includes handle housing, an electromagnetic motor mounted in the housing, and a mechanical oscillator acted upon by the motor. One end of the mechanical oscillator extends outwardly through an opening in the handle housing while the other end is attached to the housing inside the chamber. The end effector/brush head assembly attaches to the extending end of the mechanical oscillator. A power source supplies an alternating current drive signal to the motor, in turn causing the armature and the mechanical oscillator to oscillate and drive the brush head assembly. Control circuitry senses the frequency of oscillation of the mechanical oscillator and controls the frequency of the drive signal to maintain the mechanical oscillator at resonance under the variety of loads imposed during use.
