Abstract:
An electronic temperature control method and apparatus unit for a mixing valve for plumbing fixtures. The loop gain in the control unit is at least approximately inversely proportional to the instantaneous slope of the characteristic curve of the mixing valve, and the slope of the characteristic curve is determined from the instantaneous conditions of valve opening, hot and cold supply temperatures and mix temperatures.
Abstract:
An assembly is provided for the prevention of scalding in showers and other such installations. The assembly includes a valve assembly within a mixed water supply line and a temperature sensitive element for controlling the operation of the valve assembly. The valve assembly is preferably designed to allow some leakage when in the closed position.
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 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.
Abstract:
A filtration cartridge faucet assembly contains a filtration cartridge having a filter core that is concealed beneath a sink deck through the use of an escutcheon mount. The escutcheon mount permits access to a renewable filtration cartridge from above the sink deck while concealing and protecting the filtration body. The renewable filtration cartridge is equipped with a flow control device, as well as counter rotation devices that prevent undesirable outrotation of a threaded cap.
Abstract:
The invention relates to a sanitary proximity valving (1) having an associated control device (8) with a sensor device (9) and a valve device (10) coupled with the control device (8), whereby the control device (8), after detection of a signal by the sensor device (9), activates the valve device (10) to release water. The aim of the invention is to provide a sanitary proximity valving (1) which can be used also in the private sphere without major inconvenience, and is thus characterized in that the control device (8), after detection of a signal from one side, activates the valve device (10) to release cold water, whilst the control device (8), after detection of a signal from the other side, activates the valve device (10) to release warmer water.
Abstract:
A multifunction shower head with a housing, a fixed nozzle plate, and a rotatable nozzle shutter in which is set a screen disk and which is fixed to an adjustment ring has between the housing and the nozzle plate a guide plate with throughgoing passages and a wheel with radially extending and annularly arranged vanes, apertured regions and blocking regions. Rotation of the nozzle shutter relative to the nozzle plate and arresting or releasing of the wheel allows several types of spray to be selected.
Abstract:
A drainage fixture for a sanitary device, such as a sink, lavatory, or bathtub having a drainage socket with a drain hole includes a drainage funnel and a stationary disk inserted into the drain hole of the sanitary device. A plunger, including a plunger head and a guide element, for closing the drain hole is positioned under the stationary disk so as to be movable between a closed and an open position. The drainage funnel has an upper rim portion forming a sealing collar for the plunger head in the closed position. The upper rim portion is recessed in the drain hole so as to provide space for a longitudinal movement of the plunger head between the closed and the open positions. The stationary disk is made of ceramic material of a color adapted to the color of the ceramic material of the sanitary device and has a diameter that is smaller than the diameter of the drain hole and at least as great as the greatest diameter of the upper rim portion of the drainage funnel so that an annular gap is formed between the stationary disk and the rim of the drain hole.
Abstract:
A plaster-protective cover for bathroom fittings is mounted recessed in the wall, the cover being fixed to the buried part of the fitting and having an outwards-facing dome-shaped cap designed to protect the fitting parts inside it. The hole in the wall for the fitting is sealed by a collar-like sealing element which produces a watertight seal and which has, at the wall end, an annular flange which rests against the wall. The flange is embedded in a layer of sealing material applied following installation of the buried part of the fitting as the bed layer for subsequently laid tiling, and the flange thus seals off the edge of the hole pierced in the wall for the buried part of the fitting.
