Abstract: A wireless data exchange system is disclosed. The system includes an electronically operated appliance including a transmitter, a receiver, and a control module configured to communicate with the transmitter and receiver. The control module provides a primary mode of operation and a secondary mode of operation and includes control logic configured to selectively change the mode of operation of the electronically operated appliance. A communication device adapted to be held in the hand of a user is configured to cooperate with the transmitter and the receiver to impart instructions wirelessly to the control logic in order to change the mode of operation of the electronically operated appliance upon receipt of a command from a user. A method of exchanging data wirelessly between an apparatus and a communication device is also disclosed.

Abstract: A flushing device includes a cistern, in which at least one pressure chamber is arranged with a supply line for water and a discharge valve. At least part of the flushing water may be pressurised in the pressure chamber and may be discharged for flushing through the discharge valve. At least one pressure cylinder unit is provided, in which the flushing water may be pressurised and discharged for flushing, by means of a spring-loaded pressure piston. The pressure piston is preferably held in a starting position and may be released for a flushing execution. Should two pressure cylinder units be provided, either a partial or a complete flushing operation may be selected.

Abstract: A toilet system comprises a liquid receptacle and a control element. The control element configured to automatically control an amount of liquid input to the liquid receptacle for each of a plurality of flushes of the liquid receptacle such that an amount of the liquid residing in the liquid receptacle between flushes is substantially varied thereby impeding formation of a chemical deposit ring on an inner surface of the liquid receptacle.

Abstract: A remotely managed electronic dispensing apparatus having a transmitter for transmitting a detection signal and a receiver for receiving a reflected signal and a communication signal is disclosed. When the detection signal is reflected from an object, the dispensing apparatus opens a valve allowing fluid to flow. The communication signal may contain software update or other information for the dispensing apparatus.

Abstract: A remotely managed electronically operated dispensing apparatus having a transmitter for transmitting a detection signal and a communication signal is disclosed. When the detection signal is reflected from an object, the dispensing apparatus opens a valve allowing fluid to flow. The communication signal may contain maintenance, status and other information and is received by a communication device.

Abstract: A toilet system which can be rinsed by a rinsing device. A pipe is connected to the toilet pan and leads to a sanitation pipe. Means are provided for transporting a suction material from the toilet pan into the pipe and into the sanitation pipe. Said means comprise two valves which are arranged in the pipe and a pressure chamber is disposed in-between. In order to suction the suction material from the toilet pan, low pressure is produced in the pressure chamber and used to transport said suctioned material. The pressure chamber is embodied as a piston cylinder and the piston is connected to a controllable drive in order to produce the high and low pressure. The inventive toilet system enables rinsing to occur using a very small amount of water and which can be adapted to different toilet pans.

Abstract: A pressurized water closet flushing system for flushing a toilet includes a water vessel having at least one opening for receiving water. A fill tube and a discharge tube extending into the vessel are secured to the vessel. A modular assembly cap including an intake and an actuator covers the opening. The fill tube remains secured to the vessel when the assembly cap is removed from the vessel.

Abstract: An improved control valve in combination with a pressurized water closet having a housing, a spool rotatable within the housing, a valve stem threading engaging the spool but fixed from rotating relative to the housing and a needle valve extending from the valve stem and into the housing orifice, creating a self cleaning valve adjustable by rotating the spool, which adjusts the depth of the needle valve in the orifice, and thus adjusting the effective opening of the orifice.

Abstract: For pressure testing a drain and vent piping system communicating with a tub opening having an anchoring structure a plug has a central, axially extending aperture therethrough. The plug has a resilient, compressible portion and is provided with inner and outer ends. An anchor is located at the inner end of the plug and extends axially beyond the inner end to engage with the anchoring structure and seal the tub opening. The test plug assembly also includes a threaded shaft that passes through the aperture in the plug and connects to the anchor. A manually operated threaded actuator is located at the outer end of the plug and is configured for threadingly engaging the shaft to draw the actuator towards the anchor and compress the compressible portion of the plug to block fluid flow through the bath tub opening and permit pressure testing of the drain and vent piping system.

Abstract: An inner and an outer body are clamped toward opposite faces of a tub wall over a tub overflow opening. Excess water flows from the tub through an overflow outlet water passage extending through the inner and outer bodies. A water inlet passage has an inlet in the outer body and a non-circular outlet in the inner body. Flow from the tub into the water supply is prevented by a check valve in the water inlet passage. An inlet water conditioning assembly is supported at the outlet of the water inlet passage to provide a smooth, controlled, laminar cascading flow into the tub. The inlet water conditioning assembly includes a flow straightener with parallel blades parallel to the flow direction dividing the total flow into segments that are reunited in a header region at the outlet of the flow straightener. A screen assembly downstream from the header region includes a number of wire mesh screen laminas each having a wire direction angularly offset from the wire direction of adjacent screens.

Abstract: An odor trap has a basin-shaped housing and a collecting basin, which forms an inlet. Inserted into the housing is a siphon which prevents the passage of gas from an outlet to the inlet. A deodorizing insert is located on a screen below the inlet in an essentially dry area. Air ascending out of the siphon flows over the deodorizing insert and is thereby deodorized. The deodorizing insert is located under a cover and can be replaced along with the siphon.
