Abstract: A system and method for controlling a mixing system at a peak energy efficiency point, maximum response point or reduced sound generation point based on displacement, velocity, acceleration or jerk operating conditions.

Abstract: A compressed air or gas operated vibrator that has a cylindrical housing with a raceway located and formed therein. The raceway is sized and shaped for guiding a rolling member along an orbital path. The vibrator also includes at least one removable end cap for closing any open ends of the housing. The cylindrical housing has an inlet port for directing a flow or jet of the compressed gas to and towards a selected point of the raceway. The vibrator also has an outlet port for exhausting gas from the housing. The vibrator further includes a turbine wheel that rotates inside of the housing with a predetermined clearance. The turbine wheel has a plurality of blade members formed along its outer diameter and a recess portion that is formed into its outer diameter for allowing the rolling member to reside therein while also allowing the rolling thereof.

Abstract: A side-by-side coil inductor includes a first coil comprising a plurality of conductive first coil segments positioned one above another and connected in series. A second coil includes a plurality of conductive second coil segments positioned above one another and connected together in series. The first and second coil are in side-by-side position relative to one another and are connected together in series. Each of the first and second coil are approximately circular or square in configuration and the total configuration of the two coils is rectangular.

Abstract: An air-driven dental scaler has a scaling tool vibrated at a high frequency and low amplitude by a vibratory transducer having a ball within a chamber, a race in the chamber, and air inlets and air outlets arranged for admitting air under pressure into the chamber and directing the air toward the ball adjacent one of the opposite poles of the ball, the relative dimensions of the chamber and the ball providing a relatively small clearance between the ball and the chamber for enabling relatively high speed rotation of the ball within the race in the chamber, in response to the passage of the air under pressure through the inlets into the chamber and through the outlets out of the chamber, and the concomitant transmission of relatively high frequency, low amplitude vibrational energy from the rotating ball to the scaling tool.

Abstract: The present invention is for a backpack sprayer which has a reservoir tank fixedly attached to a support frame, the tank having a fill opening located at the top end and a pressure vessel located therein. The pressure vessel has a pump housing located therein which has a one way check valve leading into the pressure vessel, the pump housing also having a cylinder actuated by a hand crank for compressing the sprayed liquid into the pressure vessel. The pressure vessel expels the compressed liquid through a hand held wand operated by the user.

Abstract: The housing of a rotary ball type industrial vibrator is injection molded from a reinforced plastic material, and an annular metal raceway structure is molded integrally with the housing and forms a contact surface for a metal ball disposed within the interior of the housing. In response to a flow of pressurized air through the housing, the ball is rapidly rotated around the metal raceway to impart oscillating vibrational forces which are transmitted through the housing to a bulk material handling structure to which it is rigidly secured. The light weight plastic housing facilitates a highly efficient vibrational force transfer to the material handling structure, and the integrally molded metal raceway structure isolates the rotating ball from the interior plastic housing surface to prevent internal housing abrasion, and significantly reduces operational noise generation.

Abstract: This invention pertains to unidirectional vibration apparatus using resilient shock absorber mounting means to change multidirectional vibration into unidirectional vibration forces. Two embodiments are directed to a motor means, usually electric, which drive one or more eccentric weights at the desired speed. In each embodiment the motor is carried by a ring mounted and secured to a resilient disk. One or more weights are carried on a shaft in axial alignment with the motor shaft.

Abstract: A rotary vibrator having a cylindrical shape and an outer cam strip running the length thereof is mounted in a housing which has a matching inner cam strip and is affixed to a structure to be vibrated. Vibrator migratory movement during operation causes the vibrator cam strip to engage the adjacent surface of the housing and the housing cam strip to engage the adjacent surface of the vibrator. This wedging effect gives rise to a third point of vibrator-housing contact located essentially equidistant from the other two contact points and displaced therefrom approximately 120.degree.. Thus, a secure inter-locking between the vibrator and its mount is achieved. A source of compressed gas may be attached at either end of the vibrator and an exhaust outlet located in the vibrator directs the pressurized driving fluid into the space between the vibrator and housing for vibrator cleaning and lubrication and for quieter vibrator operation.

Abstract: This invention pertains to unidirectional vibration apparatus using resilient shock absorber mounting means to change multidirectional vibration into unidirectional vibration forces. Three embodiments pertain to the use of pressurized air for driving an eccentric weight at a desired speed. One embodiment employs a turbine which is carried between and by resilient disk members secured to mounting rings. A roller is driven by pressurized air and the vibrating apparatus is carried within and by a resilient ring. A ball vibrator also uses a resilient ring as a shock absorber.
