摘要:
A suppression unit includes a nozzle, a casing, and a biasing device. The nozzle includes an exterior surface, an interior bore extending along a longitudinal axis, and a plurality of discharge orifices passing from the interior bore to the exterior surface. The casing includes an interior surface and an exterior surface. The nozzle is disposed within the casing. The discharge orifices are covered by the casing in a biased passive condition of the nozzle, and the discharge orifices are moved longitudinally out of the casing in an active condition of the nozzle. The biasing device is disposed in a spring chamber between the nozzle and the casing. The spring chamber is fluidically isolated from the nozzle in the active and passive conditions.

The invention relates to a dental unit and a method for feeding water to instruments and/or to other water outlet points of a dental unit. The object of the invention is to enable keeping pressure of the water lines of a dental unit essentially stable, especially also when the relatively stable pressure typical for public water systems cannot be taken advantage of because of potential backflow of water contaminated at the point of use to the public water system. According to the invention there is arranged a pressure chamber (12) to the feed water line (10) of a dental unit, the said pressure chamber (12) being arranged in functional connection with pressure control means (14, 15), and upstream of the said pressure chamber (12) a pump (13), which is arranged to be able to pump water to the said pressure chamber (12) also when it is pressurized.

A device for providing the edge of a starting sheet of an electrode used in the electrolytic refining or recovery of metals with a dielectric part comprises a die space, in which the edge of the starting sheet of the electrode can at least partly be fitted, and a feeding device of the dielectric material for feeding the dielectric material into the die space. The device comprises changing members of the volume of the die space for pressing the dielectric material in the die space to that edge of the starting sheet of the electrode, which is at least partly fitted in the die space.

A suppression unit includes a nozzle, an actuator piston, a casing, and a biasing device. The nozzle has an exterior surface, an interior bore extending along a longitudinal axis, and a plurality of discharge orifices passing from the interior bore to the exterior surface. The actuator piston includes an interior channel in fluid communication with the interior bore, the nozzle separably attached to the actuator piston. The actuator piston and the nozzle are disposed within the casing and the biasing device is compressible between the actuator piston and the casing. The discharge orifices are protected by the casing in a biased passive condition of the nozzle, and the discharge orifices are moved longitudinally out of the casing in an active condition of the nozzle.

A water mist fire suppression device includes a nozzle body disposed about a central axis. Also included a nozzle arrangement configured to expel water. The nozzle arrangement includes an annular groove. The nozzle arrangement also includes a micro nozzle extending from a water plenum to the annular groove, wherein the micro nozzle is angularly oriented from the central axis. The nozzle further includes a deflector lip located proximate an outlet of the nozzle, wherein the deflector lip is positioned to contact water exiting the outlet of the nozzle arrangement.
