    Abstract: An ultrasonic waterjet apparatus has a mobile generator module and a high-pressure water hose for delivering high-pressure water from the mobile generator module to a hand-held gun with a trigger and an ultrasonic nozzle. An ultrasonic generator transmits high-frequency electrical pulses to a piezoelectric or magnetostrictive transducer which vibrates to modulate a high-pressure waterjet flowing through the nozzle. The waterjet exiting the ultrasonic nozzle is pulsed into mini slugs of water. The ultrasonic waterjet apparatus may be used to cut and de-burr materials, to clean and de-coat surfaces, and to break rocks. The ultrasonic waterjet apparatus performs these tasks with much greater efficiency than conventional continuous-flow waterjet systems because of the repetitive waterhammer effect. A nozzle with multiple exit orifices or a rotating nozzle may be provided in lieu of a nozzle with a single exit orifice to render cleaning and de-coating large surfaces more efficient.

  • Patent number: 8056830
    Abstract: A shower head designed to produce a consistent, wide diameter spray of water under both high and low water pressure conditions. The shower head includes a spinner tube mounted inside a cylindrical-shaped nozzle body. The upper segment of the spinner tube is held in a central location inside the nozzle body by a fixed cassette assembly. The middle and lower segments of the spinner tube extend below the cassette assembly and are bent outward and axially offset from the upper segment and from each other so that the spinner tube is able to spin freely inside the nozzle body. Mounted inside and over the upper end opening of the nozzle tube is an adapter with a longitudinally aligned threaded cavity formed on one end. The adapter includes a water orifice that delivers water from the shower head fixture tube to to the spinner tube. Disposed between the adapter and the upper end of the spinner tube is a flat washer with a narrow water orifice that delivers a narrow, high velocity stream of water to the spinner tube.

  • Patent number: 8051529
    Abstract: A material-removal system can include a spray-head assembly with a plurality of rotatable fluid bars arranged in a single shroud with overlapping sweeps. A gear-box assembly can index the rotations of the fluid bars to coordinate their rotation and prevent the fluid bars from interfering with one another. The material-removal system can be mounted on a mobile platform, such as a vehicle. The vehicle can have a fluid-storage tank and a debris tank that can be tilted for dumping operation while the fluid-storage tank remains stationary. A peristaltic pump can advantageously remove liquid waste from the debris tank while a vacuum system has the debris tank operating under vacuum. The spray-head assembly can be coupled to the vehicle with an articulating-arm assembly that can include a four-bar mechanism and a pair of rotary actuators to facilitate vertical and rotational movement of the arm assembly and the spray-head assembly.

  • Patent number: 8016210
    Abstract: A high pressure rotary nozzle having a rotating shaft operating within a fixed housing wherein the of axial force which acts upon the shaft due to the fluid pressure at the shaft inlet is balanced by allowing passage of a small amount of the pressurized fluid to be bled to an area or chamber between the outside of the opposite end of the shaft and the inside of the housing where the fluid pressure can act axially in an opposing direction upon the shaft to balance the axial inlet force. The balance of axial forces is self-regulating by controlling escape of the fluid through a tapered or frusto-conical region between the shaft and housing. This further provides a fluid bearing between the two surfaces and allows use of interchangeable rotating jet heads having jet orifices which can be oriented in virtually any desirable configuration including axially forward of the nozzle.

  • Patent number: 7819339
    Abstract: A self-governing spray apparatus for irrigation or cleaning purposes is provided. A spray nozzle at the end of a moment arm and substantially perpendicular to an axis of rotation creates a reaction torque to distribute a spray by spinning. A hinged member thrust into the spray pattern a centrifugal force caused by the spin deflects a portion of the spray and results in a braking action. An equilibrium angular speed is thereby reached by a self-correcting mechanism.

  • Patent number: 7654097
    Abstract: An ice distribution device for delivering ice to an ice retaining unit is provided, whereby a nozzle of the distribution device is adapted to be rotated in an eccentric rotation when installed at an upper end of an ice retaining unit, such that, when it is rotated about its axis, forces acting inside an eccentrically mounted nozzle will produce both axial and lateral components, with the lateral components of force providing a controlled “wobble”, that will deliver a substantially uniform distribution of ice within the retaining unit. A sensing device, which may be ultrasonic, mechanical or some other means, may be used to sense the level of build-up of ice within a retaining unit, for discontinuing the flow of ice to the distribution device, or diverting it to another ice retaining unit, as may be desired. The distribution and sensing devices are mounted on a top wall of the ice retaining unit and are adapted to accommodate top walls of such units of various thicknesses.
