Abstract: The invention discloses various embodiments of an ultrasonic motor and converter adapted to be used in home or industrial ultrasonic devices. The ultrasonic motor is generally of a piezoelectric material having a removable tip or of a design in which the complete motor is contained in a housing, which housing has electrical contact means adapted to be plugged into an adapter which, in turn, is connected to a converter. The motor is designed such that frequency sensing means is provided therein and the feedback signal is utilized by the converter to adjust itself thereto. The converter includes tuned circuit means tuned to a band including a desired frequency for sustaining the vibration of said motor at the desired frequency.

Abstract: Ultrasonic systems for use in consumer, and other applications, having electromechanical motor systems providing bursts of ultrasonic mechanical vibration at an applicator repeated at a sonic frequency to produce both ultrasonic and sonic vibratory motion and effect during use of said applicator.

Abstract: This invention relates to the method of manufacturing a toothbrush adapted to be mounted on an automatic toothbrush power handle, and having as a power source vibratory energy in the ultrasonic range. The manufacturing process includes that of providing a plastic brush having a head portion including a plurality of apertures and positioning a bristle cluster respectively in each aperture; and effecting a flow of the plastic in the head portion into substantially surrounding relationship of the bristles in each aperture therein, such that the plastic solidifies in adhesive relationship to the bristles to transmit the ultrasonic vibratory energy from the brush head portion to the bristles.

Abstract: The invention discloses various embodiments of an ultrasonic kit adapted to be used in the home or for industrial purposes, as well as a variety of ultrasonic motor constructions and ultrasonic converter designs to be used either individually or in combination with each other. The ultrasonic motor is generally of a piezoelectric material having a removable tip or of a design in which the complete motor is contained in a housing, which housing has electrical contact means adapted to be plugged into an adapter which, in turn, is connected to a converter. The motor may be designed such that frequency sensing is provided therein and the feedback signal is utilized by the generator to adjust itself thereto.
