Abstract: This invention is directed to a nozzle or spout for a sanitary fitting, which is arranged and constructed to reduce the noise of fluid, (water), as it flows through the nozzle or spout passageway and which also removes particles entrained in the fluid, (water), before flowing through the nozzle or spout passageways, to prevent clogging.

Abstract: This disclosure relates to a flow control device in which the discharge from the nozzle is kept at essentially the same volume rate of flow in spite of fluctuations in the hydraulic pressure upstream from the device by providing a spray body that has a group of radially disposed channels which are perpendicular to the general direction of flow. A flexible spray control washer spaced upstream from these channels responds to hydraulic pressure by pressing into the channels and restricting the flow area of each of these channels in proportion to the applied hydraulic pressure. In this way, the flow area within the chamber is inversely related to the hydraulic pressure in order to maintain a continuous volume rate of flow through the device.

Abstract: Consistency transmitters are described in which a torsional transducer is used as a flexural mount for a consistency sensor. A torsional force balance loop, in which signals from the transducer operates a torque motor to balance the torsional forces on the transducer corresponding to consistency, provides for instantaneous and continuous measurement of consistency.
