A system is disclosed for controlling the flow of a liquid from a liquid pressure line for flushing a toilet bowl comprising a valve interconnecting the liquid pressure line and the toilet bowl. An electrical control generates a first and a second timer period with the second timer period being longer in duration than the first timer period. The electrical control is connected to the valve for opening the valve for the first timer period for flushing a liquid waste from the toilet bowl and for opening the valve for the second timer period for flushing a solid waste from the toilet bowl.

Dispensing system

A system is disclosed for dispensing a liquid at a desired temperature from a hot liquid pressure line and a cold liquid pressure line to a plurality of liquid outlets such as a bathtub, a sink or the like. The system controls the temperature of the liquid flowing from the plurality of liquid outputs as well as controlling the level of liquid within a container and for maintaining the temperature of the liquid therein. The system includes a liquid recycling system which reduces the amount of liquid discarded during the operation of the system and to conserve heat energy. The system is controlled by a novel electronic control which when applied to a water dispensing system is able to control all functions of a bathtub as well as being capable of controlling a sink, a toilet or the complete water system for a residence, a hotel, an industrial or a medical complex or the like. The system also includes novel valve menas for providing liquid mixing, liquid flow control, liquid distribution and diverting, liquid draining and liquid eduction which may be useful in many liquid distribution systems independent of the examples of the liquid dispensing system set forth herein.

A flow meter having electrical signal outputs and a digital display is described. A transducer uses a magnet inside the flow meter to position a ball on a resistor bar and a contact bar and, thus, generate a position signal. The position signal provides an accurate electrical indication of flow to the circuitry driving the display.

A flow switch is disclosed comprising a body member having a fluid inlet and a fluid outlet defined therein. An outer core tube is disposed within the body member and has a first and a second end. An inner core tube is disposed coaxial to and within the outer core tube and has a first and a second end with the first ends of the inner and outer core tubes being disposed adjacent the fluid inlet. One of the inner and outer core tubes being in fluid communication with the fluid inlet. The body member defines a body flow path between the outer core tube and the body member and in fluid communication with the fluid outlet. A first aperture is defined by the inner core tube and a second aperture is defined by the outer core tube. Securing means secures one of the core tubes to be non-rotatable relative to the body member. The other of the core tubes is rotatable relative to the body member enabling the first aperture to register with the second aperture for defining a first orifice of variable size to provide a variable flow path from the fluid inlet to the body flow path and to the fluid outlet in accordance with the relative rotational position between the inner and outer core tubes. A cylindrical chamber is defined by the rotatable core tube. A piston is slidably disposed in the cylindrical chamber for movement in accordance with the fluid flow through the fluid inlet. A switch is disposed proximate the piston for providing a switching output in response to the fluid flow through the fluid inlet exceeding a preselected level.

Fluid flow switch

A flowmeter for measuring the flow rate of a liquid or gaseous media is disclosed. The flowmeter comprises a body portion including an inlet and an outlet. A fluid path extends between the inlet and the outlet. A core tube is disposed vertically within the body portion and a recessed groove is defined by the core tube. The groove extends longitudinally relative to the core tube and a first piston is movably disposed within the core tube and disposed adjacent the groove. A cross sectional area of the fluid path is defined by the groove and the first piston, the cross sectional area of the fluid path being variably dependent upon the longitudinal disposition of the first piston relative to the groove. A cover tube is disposed adjacent the body portion and in fluid communication with the fluid path. A second piston is disposed within the cover tube and is connected to the first piston by a connecting means enabling the first and second pistons to move in unison. A first and a second side of the second piston are immersed in a static fluid enabling controlled damping of the first piston and an indicator cooperating with the second piston indicates the position thereof relative to the cover tube. An embodiment is disclosed for measuring gaseous flow in which the indicator is operative within a range dependent upon the buoyancy of the connecting means immersed in the static fluid.

Flowmeter

An improved flowmeter is disclosed for measuring the flow rate of a fluid such as a gas or a liquid. The flowmeter comprises a body portion including a fluid inlet and a fluid outlet. A core tube is vertically disposed within the body portion to be in fluid communication with the fluid inlet. A tapered recessed groove extends along the core tube to provide a fluid path adjacent the core tube in fluid communication with at least the fluid outlet of the body portion. A piston is located within the core tube to expose a variable amount of the tapered recessed groove to the fluid inlet upon movement of the piston within the core tube. The fluid flow moves the piston relative to the recessed groove to an equilibrium position determined by a single cross-sectional area of the tapered recessed groove for a given flow. Means are provided for indicating the position of the piston for determining the volumetric flow rate of the fluid.
