A sprinkler assembly with a nutating distribution plate can improve even distribution of water. The distribution plate can tilt and/or translate upon water impinging the distribution plate to disperse water in different directions. The sprinkler assembly can have a deflector assembly including the distribution plate, a stem supported by a bearing, and a contact portion upstream of the distribution plate to contact an outer race that limits a range of movement of the distribution plate. The sprinkler assembly can be disassembled and reassembled with minimal tools and effort for servicing.

A cleaning apparatus having a door assembly sealable against the door opening of the sterilizing machine by an inflatable seal connected to an air chuck on the cleaning apparatus is operable to descale a sterilizing machine. The cleaning apparatus includes separate tanks for storing and dispensing cleaning fluid and rinse fluid. A pump associated with each tank sends fluid into the spray wand for distribution within the sterilizer machine. A vacuum is created within the corresponding tank and to draw fluid from the sterilizer machine back into the selected tank. The spray wand can be moved linearly and rotationally to direct the fluid throughout the interior of the sterilizing machine with the fluid being recycled back into the tank through a vacuum port. A selector valve on the cleaning apparatus allows the selection of cleaning fluid or rinse fluid to be drawn into the sterilizing machine.

A surface treatment assembly for treating a contoured surface includes a surface treatment array formed from a plurality of base structures, each base structure operably coupled to a first phalange structure and a first phalange structure first end. A second phalange structure operatively coupled to each first phalange structure and a phalange joint disposed between each first phalange structure and each second phalange, thereby forming a finger structure. Moreover, at least one applicator head is coupled to a second phalange structure second end of each finger structure and configured to treat the contoured surface. A base structure actuator and a phalange joint actuator operatively coupled to and configured to manipulate the first phalange structure and the second phalange of each finger structure to adjust the surface treatment array relative to the contoured surface.

A washing device 1 includes an inner tube 13 pivotally supported rotatably, a turning shaft 14 provided in a direction substantially orthogonal to the inner tube 13 and pivotally supported rotatably at a distal end of the inner tube 13, and a nozzle 3 provided on the turning shaft 14, and the nozzle 3 is rotated in a revolving direction and in a rotating direction by a first motor 25 and a second motor 28. A revolving direction model 41a for setting an operation of the nozzle 3 in the revolving direction and a rotating direction model 41b for setting the operation of the nozzle in the rotating direction are displayed on display means 7, and a movement locus of the nozzle is prepared from the set operations of the nozzle in the revolving direction and in the rotating direction.

The present invention provides a technique in which service life of a coolant application device can be extended. The coolant application device includes a nozzle body which spouts coolant, a hollow shaft which rotates the nozzle body, a motor which controls a rotation angle of the hollow shaft, and an Oldham coupling portion which connects the hollow shaft and an output shaft of the motor, the Oldham coupling portion transmits driving force of the motor to the hollow shaft, allowing a misalignment between an axis of the hollow shaft and an axis of the output shaft.

The present disclosure describes a system and method of depositing ceramic or ceramic composite coatings on the inside surface area of a tubular shape. The system and method described herein can provide an interior coating for tubes and pipes to provide wear resistance, abrasion resistance, and anti-scaling effects.

A nozzle apparatus may comprise a nozzle body having a nozzle tip with a discharge port for spraying a treatment fluid onto a substrate; a nozzle moving member for moving the nozzle body relative to the substrate; a rotating member for rotating the nozzle body or the nozzle tip so that a treatment fluid is sprayed onto the substrate during rotation; and a control unit configured to control an operation of the nozzle moving member and the rotating member.

A water feed tube assembly for a dishwasher with a water feed tube having one or more inlets and outlets and front, back, and side walls. At least one outlet is positioned on the front wall of the water feed tube. The water feed tube includes a manifold docking retainer that is integral with the water feed tube at a position adjacent to the outlet. The manifold docking retainer includes first and second ears that are positioned on and extend integrally from the side walls of the water feed tube such that the first and second ears of the manifold docking retainer are configured to receive first and second docking arms of a spray arm manifold. The manifold docking retainer includes first and second knobs that are positioned on and extend integrally from the front wall of the water feed tube to mate with the spray arm manifold.

A laminar device is provided. The laminar device includes a collar, an arm lid plate, a first bracket, a second bracket, and a laminar body. The arm lid plate is rotatably enclosed in the collar. The first bracket is opposite the second bracket and extends downwardly in a same direction from the arm lid plate. The laminar body is rotatably coupled to the first bracket and the second bracket and rotates and tilts to create one or more water features.
