Abstract: A sanitary valve assembly for controlling the flow of hot and cold water, which includes at least two superimposed annular control elements arranged and constructed to provide at least two passgeways therethrough with a control lever operable coupled to one of the control elements for proportioning both hot and cold water therethrough. The control elements are formed having reduced surface areas for effecting a watertight seal.

Abstract: The disclosure and drawings describe and illustrate a water mixer fitting having a temperature measuring means operatively coupled between the mixed water outlet opening and a display terminal disposed in or adjacent to the handle assembly.

Abstract: The present invention is directed to a straight-way and shut-off valve in which identical discs are arranged in face-to-face contact to provide a fluid-tight seal therebetween and means are provided whereby fluid is not trapped between the central rotatable disc and an outer disc so that upon expansion of the fluid, the discs do not shift outwardly due to axial pressure that would break the fluid-tight seal.

Abstract: A single-lever sanitary water valve is provided with a fixed cylinder which has at least one water inlet aperture and serves to receive a rotatable and/or slidable piston, by means of which the inlet aperture can be wholly or partly closed and can be linked to the outlet aperture, the slidable and/or rotatable piston being controlled by means of a lever assembly. The lever assembly includes a rotatable cap mounted on the valve body to which is coupled the piston and the adjusting lever via at least two linkage members so that first, second and third pivot bearings are formed at their respective points of connections whereby lateral forces acting on the piston are substantially eliminated when the adjusting lever is shifted between its raised and lowered positions.

Abstract: A straight-way valve comprising a valve body having regulating elements is mounted therein. The valve regulating elements include a plurality of discs, one of which is mounted for rotation and at least one of the other discs is statically mounted in valve body. The rotatable disc has a plurality of flow ports, which correspond with flow ports formed in the at least one static disc. The at least one static disc is arranged in face-to-face contact against the rotatable disc to form a fluid tight, mechanical seal. An actuating device is coupled to the rotatable disc and is mounted for rotation in said valve body. The actuating device includes means, which extend through the valve body for rotating the disc from an opened to a closed position.

Abstract: A straight-way valve assembly is provided with regulating elements in the form of discs, of which one is rotatably-mounted and includes flow ports, which correspond to flow ports of the other static discs, which static discs are arranged on opposite faces of the rotatable disc to form a mechanical, fluid tight seal, whereby the face of the rotatable disc directed away from the supply line includes one or several recesses that are in fluid communication with valve vent means when the valve is in its closed position; the recesses extending radially outwards across the surfaces of the rotatable disc.

Abstract: This invention concerns a sanitary water valve having a valve assembly, which includes a cylinder having a bore extending longitudinally therethrough and at least one water inlet orifice and a water outlet orifice formed in the cylinder wall; and a slot or opening, extending longitudinally over the length of the cylinder wall. The at least one water inlet orifice and water outlet orifice are formed on the cylinder and positioned the same longitudinal distance from one end thereof. A piston is positioned in the cylinder bore and is rotatably and longitudinally shiftable therein, the piston including a water mixing chamber in the form of a transverse slot or water passage, which is arranged and constructed to connect with at least one water inlet orifice and the water outlet orifice.

Abstract: A row-crop harvester has a frame displaceable along the ground and formed with a plurality of forwardly opening throats at each of which is provided an endless conveyor chain spanned over a drive sprocket and an idler sprocket. A fluid cylinder mounted on the frame is provided for each of the idler sprockets so that when this cylinder is pressurized it can urge the respective idler sprocket away from the respective drive sprocket and tension the respective conveyor chain. A pressure-responsive switch is connected to each of the fluid cylinders and to a magnetic clutch between the drive for the chopper and drive sprockets for the harvester. When the pressure drops suddenly in any of the cylinders, as happens when a chain breaks, his pressure-responsive switch will respond and open the clutch to shut down the harvester.
