Provided are gas distribution apparatus with a delivery channel having an inlet end, an outlet end and a plurality of apertures spaced along the length. The inlet end is connectable to an inlet gas source and the outlet end is connectable with a vacuum source. Also provided are gas distribution apparatus with spiral delivery channels, intertwined spiral delivery channels, splitting delivery channels, merging delivery channels and shaped delivery channels in which an inlet end and outlet end are configured for rapid exchange of gas within the delivery channels.

A device for grinding and reducing food waste to be disposed of in sewage systems. The device eliminates disagreeable odours by flooding the grinding chamber with water using a swivel plug that retains a gap of fresh water from the last use of the tap. The fresh water serves as a barrier to odors by creating a partition, isolating the dirty water in the grinding chamber. The matter to be grinded is segmented and torn up several times by a grinding apparatus made of cutting blades while it swirls in the water until it is reduced to particles small enough to pass through openings in a spherical grid. The device can be adapted to different uses: residential, commercial or industrial.

A water quality and flow monitoring and control apparatus, method and system installed at an end user location and being capable of monitoring one or more of the following water quality parameters: microorganisms (including E. coli), mineral or other ion concentration, pH, temperature, and turbidity. The system also has a water meter that detects the flow of water and has a valve to shut the flow of water off upon detecting a fault condition such as a leak.

Some embodiments may include a water supply system for supplying water based on a predetermined planned daily supply amount of water. While the worries supplied, it may be determined whether a second time has reached after a predetermined time passed from a first time. When it is determined that the second time has reached, an accumulated amount of the supplied water may be measured. A difference between the measured accumulated amount of the supplied water and the planned daily supply amount of water may be calculated. The planned daily supply amount of water may be corrected by adding the calculated difference to the planned daily supply amount of water after the second time. Water may be supplied based on the corrected planned daily supply amount of water.

The invention relates to a pressure indicating device for indicating a pressure in a first fluid system, said pressure indicating device including a first port via which it is fluidically connected to the first system, which pressure indicating device furthermore comprises a cylinder with a preloaded piston that can be displaced therein in an axial direction, during which movement fluid contained in the first system can act on the piston surface. The invention is characterized in that said piston has an opening in its piston surface, which opening can be made to communicate with a second system via a second port, said piston comprising a diaphragm which is impermeable to a first fluid but permeable to a second fluid, said diaphragm separating the first port from the second port.

A tire inflation system and method for a tire supported by a wheel, the tire inflation system including a pump system including a pump cavity configured to fluidly connect to the tire, an actuating element configured to actuate relative the pump cavity, a drive mechanism rotatably coupled to the wheel, the drive mechanism including a motion transformer and an eccentric mass, a valve fluidly connecting the pump cavity to a fluid reservoir; and a control system configured to operate the valve.
