Abstract: A water jet assembly includes a faceplate with at least one opening, a housing constructed to cooperate with the faceplate, and a mover disposed within a chamber of the housing. The mover is configured to move between a first position adjacent the at least one opening of the face plate and a second position offset from the faceplate to provide a variable volume within the chamber. The water jet assembly also includes an exciter connected to the housing and configured to transition the mover between the first position and the second position to increase and decrease the volume to move fluid into and out of the chamber via the at least one opening.

Abstract: A device and method for producing pulsating waves of energy for the massaging effect normally associated with high pressure jet systems in whirlpools, pedicure spas, bathtubs and other medical and non-medical devices. The jet assembly includes no external pipes and unlike “pipeless” jet assembly systems in use today, does not require disassembly or circulation of chemical cleaning agents to maintain a sanitary condition of the jet assembly.

Abstract: A self-propelled concrete finishing trowel has a steering system that counteracts a portion of the load associated with operator manipulation of a steering handle. A steering linkage connects the steering handle to a rotor assembly. A steering assist mechanism, preferably including a torsion bar or a spring, imposes a preload on the steering linkage to reduce handle actuation forces. The steering assist mechanism reduces handle retention forces, required to maintain the handle in a particular position after moving the handle to that position, to less than about 20 lbs throughout the stroke of the operating handle.
