Abstract: This invention relates to a method for mounting micro jets on whirlpool bath surfaces. Micro jets are mounted in the bottom of cups. The cup containing the micro jet is mounted in an opening performed in the whirlpool bath shell. The proposed method is specially interesting for jets located on surfaces where fluid flows are obstructed such as the surface where a person's back rests when someone lies in a whirlpool bath. This method allows manufacturers to install micro jets those whirlpool bath surfaces without having a recessed part. Moreover, it allows to modify easily the fluid jet pattern depending on the consumer's needs. The present invention also concerns recessed micro jets for whirlpool baths and method for mounting the same.

Abstract: An automated cleaning system, where dairy cows pass through a foot bath region. The foot bath is periodically changed by implementing an agitation phase where high velocity water jets agitate the waste material in the foot bath and causes these to be discharged, followed by a drain phase where the liquid flows out an outlet. Then, a flushing phase removes the further debris, with the foot bath then being refilled with water and chemical disinfecting liquid for a subsequent cycle where another group of cows would pass through the foot bath region.

Abstract: A whirlpool jet assembly has both an articulatable nozzle and a rotary face. The nozzle can be directed over a range of angles to provide a narrow stream of water and air to hit a selected spot. The rotary face is easily installed to fluidly and mechanically engage the end of the nozzle. When so installed, the rotary face sends the stream through at least two canted apertures which thereby generate torque to rotate a rotor in the face. The resultant circularly shaped stream impinges on a larger area. The user can readily install or remove the rotary face to select either configuration.

Abstract: A hydrotherapy jet system has a segmented outlet that extends from the jet body in response to a water flow through the jet and retracts when the flow stops. Water flows into the jet body, where it is directed into a nozzle that tapers to accelerate the water into a venturi jet that can then be aerated if desired. The water then enters the segmented outlet, which is urged to a retracted position within the jet body by a spring. The pressure from the water causes the outlet to extend from the jet housing against the spring pressure, compressing the spring. When extended, the outlet provides a stream of warm or aerated water to a reservoir such as a spa, pool or bathtub and the outlet can be manipulated to direct the stream. When the flow of water is stopped the spring expands and causes the outlet to retract into the jet body.
