Abstract: A plumbing control system includes a plurality of plumbing fixtures operated by an electronic control board having a microprocessor. The control board can form a node on a network that monitors and controls the functions of multiple boards throughout a facility from a central computer. Network software running on the central computer communicates with the control boards. The software includes a binding feature that requires reporting of a network operating variable at a first control board to the central computer or a second control board. The network software also has site and device setup forms.

Abstract: A mixing valve apparatus including a mixing valve for mixing water from a cold water inlet and a hot water inlet and supplying the mixed water to a water outlet the water inlets and outlets being for connection to an external water system, a valve servo for moving the position of the valve, a control system for operating the valve servo and thereby controlling at least the temperature at the water outlet, wherein the control system characterises the external water system in which the mixing valve is connected and optimizes control of the valve according to the characterisation.

Abstract: The present invention dispenses hot coffee or other beverage by the cup at a selected temperature, which can be varied from cup-to-cup. The beverage is brewed in a conventional way, and in one embodiment is stored in a conventional holding tank at elevated temperature. The holding tank communicates with two smaller reservoirs. A quantity of beverage is stored in a first reservoir at an elevated temperature, at or above the maximum desired dispensing temperature. A second quantity of beverage is cooled and stored in a second reservoir at a lower temperature, at or below the minimum desired dispensing temperature. When a cup of beverage is to be dispensed, the temperature is selected, and a quantity of beverage is dispensed from each of the reservoirs, proportioned so that the resulting dispensed beverage is at the selected temperature. In another embodiment, the first reservoir is omitted, and beverage from the holding tank provides the elevated temperature beverage for mixing.

Abstract: To obtain an exact regulation of temperature, a strong flow, and a moderate cost, the cartridge comprises a first disc having two transverse hot fluid passages and two transverse cold fluid passages as well as a groove, the base of which forms a seat for a regulating valve which is joined to a thermostatic element, and a second disc having two passages for hot and cold fluid respectively, and which is coupled and rotatable relative to the first disc, between a communicating position and a non-communicating position of the two hot fluid passages on the one hand and the two cold fluid passages on the other of the first disc. The cartridge may be used for thermostatic water mixer taps, in particular for sinks, washbasins, showers and bathtubs.

Abstract: A heating and air-conditioning apparatus for the cabin of a motor vehicle. The apparatus includes a chassis within which air flows and equipped with an air-blowing mechanism and heating and cooling units for cooling and heating the air and a member for controlling the heating unit. At least one airflow duct communicates with the chassis, and at least one mixing shutter, with a variable degree of openness, controls the air stream towards the duct. The mixing shutter is arranged in the overall direction of the air flow downstream of the heating member and transmits additional air passing through the heating unit when the fresh air passage is wide open, and governs in an intermediate position of closure of the air flowing through the heating unit. The mixing shutter also switching a control member controlling the operation of the heating unit between an off and on position.

Abstract: A retrofit automatic temperature controlling apparatus and kit is attached to a prior art steam-cold water mixing valve assembly to produce mixed cold water and steam as hot water at a controlled temperature. An adjustment screw is added to the prior art valve assembly to limit the displacement of a steam poppet valve which is opened by a retrofitted piston. Cold water is redirected to a retrofit temperature control assembly having a mixing chamber for receiving the cold water. A water and steam receiving conduit terminates in the mixing chamber and has fluid isolated sections for receiving steam and cold water with a sleeve valve member for selectively coupling the steam and cold water sections to the mixing chamber. The sleeve valve member is operated by a temperature sensing device in the outlet hot water chamber. A disc member separates the mixing chamber and outlet hot water chamber with small passages which promote mixing.

Abstract: Disclosed herein are storage type water heaters having means for improved mixing of cold water supply with water stored in the water tank of a water heater, means for limiting surges of water into and out of a water tank, and means for disrupting formation and propagation of convection currents and water streamers in a water tank.

Abstract: A temperature-actuated mixing valve for controlling outlet temperature in a fluid flow system including a valve housing having first and second inlets for introducing first and second respective supply fluids and an outlet. A shuttle assembly is positioned in the housing. A valve member is mounted within the housing and responds to the temperature of the supply fluids to vary their mixture ratio to dispense fluid at an outflow temperature. A shuttle member is positioned within the valve member, is moveable responsive to supply fluid temperature variation, and includes an elongate grip pad for manual removal of the shuttle member from the housing. A thermal actuator converts thermal energy into mechanical movement using a piston. A spring maintains the valve and shuttle members in a stationary condition relative to each other and permits movement of the shuttle member relative to the valve member for accommodating movement of the piston when the valve member has reached its limit of travel.

Abstract: A housing (1) has a chamber (10) comprising fluid accesses (41, 42, 43, 44), at least one of which can be plugged by a plug (2); a reversible motor (6) equipped with a rotary shaft is connected to the plug by a coupling (7) involving a screw-nut system (71) to move it in translation towards plugging or uncovering the pluggable access (41) according to the temperature of a stream of fluid travelling through the device; and a thermostatic element (8) located in the same stream of fluid actuates the plug if the motor or its controls fail.

Abstract: The invention relates to a device for controlling the flow of a fluid, housed in a thermostatic faucet comprising:
