The present invention discloses an integrated supplying apparatus for gas and sizing. It comprises a sizing barrel, a gas supply unit and a switching unit. The sizing barrel and the gas supply unit are both connected with the switching unit. When the switching unit is fixed in a first state by a safety component, the gas supply unit can only output high pressure gas through the switching unit. When the switching unit is converted into a second state by releasing the safety component, the gas supply unit in turn outputs some high pressure air into the sizing barrel through the switching unit, so that the sizing inside the sizing barrel is output under the action of the gas pressure and the gas inside the sizing barrel is then output when completing the output of the sizing.

A solar hot water system is provided, comprising an ambient temperature sensor, a controller, a valve, a water storage tank, having an inlet and an outlet, and at least a first solar panel, having an inlet in fluid communication with the water storage tank outlet and an outlet in fluid communication with the water storage tank inlet. When the temperature sensor indicates to the controller that the ambient temperature is above a predetermined level, the controller controls the valve to direct flow from the water storage tank outlet to the solar panel inlet and from the solar panel outlet to the water storage tank inlet. When the temperature sensor indicates to the controller that the ambient temperature is below a predetermined level, the controller controls the valve to direct flow from the solar panel inlet to the valve and so to atmosphere.

The exhaust gas recirculation valve comprises a tubular valve housing includes a gas inlet, a first gas outlet and a second gas outlet located proximate thereto. Located inside the tubular valve housing is a rotatably supported valve body that is designed as a hollow body having a semi-cylindrical lateral surface having a lateral penetration opening. The gas inlet as seen from the top includes a blocking wall on the side thereof facing the first gas outlet and the second gas outlet, the blocking wall being located inside the valve housing perpendicular thereto and having a height equal to at least the length of the valve body and sitting flush against the gas passage in the closed position of the exhaust gas recirculation valve.

A diverter valve is provided for an extruder, especially a twin-screw extruder, that allows for the replacement of the extruder screws without dismounting the same. The diverter valve includes a valve housing with a first flow passage, which can be fastened indirectly or directly to an extruder cylinder, whereby the valve housing can be arranged on the extruder cylinder with the first flow passage aligned with the screw area. The cross section of the first flow passage is constructed large enough to pass extruder screws arranged in the extruder through the flow passage. The diverter valve further includes a valve bolt having its axis arranged basically perpendicular in relation to the direction of flow of a liquid or a melt, with at least an additional flow passage, which can be oriented in alignment with the first flow passage of the valve housing and whose cross section is likewise constructed large enough to pass extruder screws arranged in the extruder through this second flow passage, whereby the valve bolt is arranged adjustably in the valve housing.

The present invention relates to systems for circulating water in a potable water piping network to prevent the stagnation of water in this piping network. Several systems are disclosed wherein partitioned pipes, pumps, partitioned headers, check valves, and scoop inserts are used to keep the water in movement inside the pipes. The present invention comprises several pumping arrangements for circulating water inside fire hydrant laterals and inside the branch pipes along dead-end streets where most of the water stagnation occurs. Although partitioned pipes are used and opposite flows are induced in opposite pipe halves, full pipe flow to each hydrant is maintainable in case of emergency. Inside buildings, the water is kept in movement inside a loop pipe that extends close to each water outlet such that the water is maintained fresh at each outlet.

The body of the valve has two outlets whose axes are offset in the direction of the axis of the mounting base by a distance greater than 5 mm, typically between 20 and 60 mm, the spacing between the outlet axes being greater than 60 mm and typically less than 130 mm. This arrangement avoids problems of positioning and collision between the upstream circuitry connected to the outlets in the use configuration of the valve on a dive tank.

An apparatus for supplying a slurry to a polishing surface has a slurry source, a slurry supply line, and a slurry return line. The slurry supply line and slurry return line are configured so that slurry may be directed from the outlet of the slurry supply line onto the polishing surface during a chemical mechanical polishing operation, or into an inlet of the slurry return line after the polishing operation is stopped. This permits continuous circulation of slurry through the slurry supply line to prevent coagulation.
