Abstract: A mixer (1) for processing one or more fluid media (2) and optionally one or more solid media (3). The mixer (1) consists of a tank (4) with one or more filling openings (5) and a discharge opening (6) at the bottom of the tank (4), and a mixer unit (8) provided at the bottom of the tank. The mixer unit (8) includes a rotor (9), an inlet (10) and an outlet (11). The mixer unit (8) also includes a valve arrangement (12) with a valve body (13), an inlet (14) communicating with the outlet of the mixer unit (8), a first outlet (14) communicating with the discharge opening (6) of the tank and a second outlet (15) communicating with an inlet in the tank (4). A connection (20) may be provided between the first outlet (15) of the valve arrangement and at least one of the filling openings of the tank.

Abstract: An apparatus for ejecting balls in which a pretensioning arrangement includes a loading device which is displaceable between a first and a second position, first and second locking members are brought to contact each other by displacement of the loading device to a first position as a pivot arm is thereby moved to the loading position, and displacement of the loading device to a second position produces pretensioning of the pivot arm in the loading position. As a result, the pivot arm has a position in which the apparatus is safe because the pivot arm is without tension in the shooting position. Also, the pivot arm can be moved to its loading position without a simultaneous pretensioning being effected. Pretensioning is only established when the pivot arms are in the loading position and are retained by the locking arrangement. Thus, the loading arrangement and shooting power can be varied.

Abstract: The present invention concerns a valve (1), a valve closing body (14) and use of a valve (1) and a valve closing body (14) of the type used for injecting dry powder which is mixed with liquid, and where the dry powder is supplied under the liquid surface in a mixing vessel (11) in which a vacuum is typically maintained. The novel feature of a powder valve (1) according to the invention is that a closing body (14) of the valve in the closed position extends through the valve seat (13) of the valve and into the wet environment. It is hereby achieved that when the valve (1) is opened, powder or dust from powder is not deposited on the valve closing body (14). This is in spite of the valve closing body (14) being wet, due to contact with the liquid to which the powder is added. Due to its elongated shape, the valve closing body (14), which in the withdrawn position opens for inflow of powder, has the property that the inflowing powder dries the valve closing body (14) at first and keeps it dry subsequently.

Abstract: An apparatus for ejecting balls including: a frame supporting a ball holder; an ejecting arrangement adapted for ejecting the ball from the ball holder; and a control unit; the ejecting arrangement including a spring-biased pivot arm which is pivotable about a shaft and has an impact face spaced apart from the shaft, where the pivot arm has a circular path with a first extreme position where the pre-tensioning of the pivot arm is maximal, and a second extreme position where the pre-tensioning of the pivot arm is minimal, where the ball holder and the impact face are arranged such that the ball is hit by the impact face during the working stroke of the pivot arm in a direction from the first towards the second extreme position, at which the frame further supports a spring-biased pivotable braking plate with one or more vertically oriented springs.

Abstract: An endless conveyor has a driven drum that rotates about its axis. A flexible band forms a helix by being wrapped around the drum. A fixed helical support supports the outer edge of the band. A secondary conveyor moves an endless series of stacking blocks. The stacking blocks are in frictional engagement with the drum to transfer driving forces from the drum to the blocks. The stacking blocks also keep the turns of the flexible band spaced apart by a distance equal to the height of the blocks. The secondary conveyor includes guides at both the top and bottom of the drum to guide the stacking blocks into and out of engagement with the inner edge of the flexible band. The stacking blocks are in slip-free and backlash free engagement with the inner edge of the flexible band, and the frictional engagement between the stacking blocks and the drum permits the stacking blocks to be displaced both axially and circumferentially on the surface of the drum.
