Abstract: A downhole vibration tool includes a body, a mandrel, a spring, and a balance piston. The body may be generally tubular and may have one or more helical slots formed on an inner surface thereof. The mandrel may be generally tubular, may have a bore, and may be positioned at least partially within the body. The mandrel may have one or more helical splines formed on an outer surface of the mandrel, the helical splines engaging the helical slots of the body such that the mandrel is translatable axially relative to the body. The spring may be positioned in an annular space formed between the mandrel and the body defined as a spring chamber. The balance piston may be in an annular space formed between the mandrel and the body, wherein the balance piston separates an oil-filled chamber from an internal pressure chamber.

Abstract: A dishwasher assembly may include a dishwasher rack including at least one drinkware row configured to hold drinkware along a length of the rack, a sprayer configured to provide at least one stream of liquid into the drinkware, and a paddle wheel assembly arranged between the drinkware row and the sprayer and including at least one paddle configured to rotate responsive to force of the at least one stream of liquid against the at least one paddle, such that during rotation the at least one paddle is configured to variably deflect at least a portion of the stream onto a plurality of portions of an interior surface of the drinkware.

Abstract: A dishwasher comprises a cabinet defining a wash chamber and a utensil rack mounted within the wash chamber by at least one slide. The slide comprises a track that slidably receives a wheel and includes an access opening for insertion or removal of the wheel from the track. A closure for selectively closing the access opening can prevent undesired removal of the wheel from the track. A method of removing the utensil rack comprises sliding the utensil rack to align the wheel with the access opening and lifting the utensil rack to move the wheel through the access opening.

Abstract: An automatic dishwasher comprises an open-faced cabinet defining a wash chamber and a utensil rack mounted within the wash chamber. The utensil rack comprises a frame mounted to the cabinet and a basket removably mounted to the frame, and the frame and the basket are configured such that the basket is vertically adjustable relative to the frame. Additionally, the basket comprises a plurality of basket elements that are complementary to form a whole basket. Further, the dishwasher includes a pair of slides for slidably mounting the frame to the cabinet. The slides comprise a track that slidably receives a wheel on the utensil rack and includes an access opening for insertion or removal of the wheel from the track. A closure for selectively closing the access opening prevents undesired removal of the wheel from the track.
