Abstract: A tube separator (1) having a shut-off means for separating an inlet side (2) from an outlet side (3) is provided. In order to prevent flutter of the shut-off means (4) in a pressure region changing over the shut-off means, a control valve (10) controlling the shut-off means (4) is provided. The control valve (10) is designed such that the pressure required for changing over from a first opened position to a second shut-off position is smaller than the pressure for changing over from the second into the first position.

Abstract: A tube separator (1) having a housing (2) with an inlet (5), an outlet (6) and a separating chamber (14) connectable with a drain (9) is provided. A shut-off member (10) connecting the inlet (5) with the outlet (6) in a first position thereof and separating the inlet (5) from the outlet (6) and connecting the outlet (6) with the separating chamber (14) in a second position is provided between the inlet (5) and the outlet (6). In order to prevent the entry of contaminations into the separating chamber (14) and hence into a line system connectable with the inlet (5) and the outlet (6) the separating chamber (14) is designed in a manner to be tightly sealed against contaminations. To this end preferably a filter (24) is provided between the separating chamber (14) and the drain (9).

Abstract: A tube separator (1) is provided comprising a housing (2) with inlet connection (13) and outlet connection (14) and a member (37) being disposed within the housing (2) and slidable between a first and a second end position. The member (37) comprises a channel (49) extending from an entrance opening (55) to an exit opening (56) and an area (40') on which the pressure in the inlet connection may act upon. Furthermore, a spring (46) acts upon the member (37) in a direction opposite to the action of the inlet pressure. The channel (49) forms a connection between the inlet connection (13) and the outlet connection (14) in the first end position of the member (37), and the member (37) separates the inlet connection (13) from the outlet connection (14) in the second end position of the member (37). The entrance opening (55) and the exit opening (56) each comprise a straight secant, and their respective secants being parallel to each other.

Abstract: A tube separator (1) is provided comprising a shut-off means (4) for separating an inlet side (2) from an outlet side (3) as well as a control valve (11) controlling the shut-off means (4) in dependence on the difference of the pressure at the inlet side 2 and the outlet side 3. In order to prevent a flutter of the shut-off means (4) for low flow rates a valve (42) is provided which is designed such that it releases the connection of the outlet pressure with the control valve (11) only if the flow rate of the medium drops below a certain value.

Abstract: A mobile metering apparatus is provided for metering into a liquid stream or flow an agent which is to be metered or dosed in a quantitative proportional relationship. The metering apparatus contains liquid meter through which passes the liquid flow and a metering pump connectable to a dosing agent reservoir on the input side thereof and to a metering location at the output side thereof. The metering pump meters the agent from the reservoir into the liquid flow as a function of signals supplied by the liquid meter. The liquid meter is installed in a short conduit portion provided with an inflow connection and an outflow connection. The short conduit portion, liquid meter and metering pump are mounted at a supporting frame enclosing the aforementioned members on all sides. The drive of the metering pump is accomplished by the pressure of the liquid flow.

Abstract: A method and apparatus for supplying dry detergent concentrate to a metering device for dissolving or dispersing in water which prevents or minimizes the formation of dust, lumping, caking, and encrustation of vessel walls and supplies new detergent to the laundry plant in response to changes in electrical conductivity of the wash water from a predetermined value which indicates consumption of original detergent required in soil removal and need for replenishment thereof. The minimizing of dust and protection of the detergent from moisture is accomplished by using a flexible delivery container, the filling means and emptying means of which are sealable and which emptying means acts in cooperation with the metering apparatus section to form an integral delivery system which is generally isolated from the surrounding atmosphere.
