20100090136 | PRESSURE VAVLE - A pressure valve comprises a valve bush and a control plunger which is movably guided in the valve bush and enables a pressure medium path from a pressure medium source to a consumer via the valve bush to be controlled. A collar section is provided on the control plunger, via which the cross section of a radial opening of the valve bush on the side of the pressure medium source may be modified. The pressure medium path downstream of the radial opening is guided by at least one channel which extends axially through the collar section. The pressure valve also comprises a pilot control system which is used to apply an adjustable control pressure to the control plunger; a control pressure medium supply channel comprising an inlet opening is provided on the control plunger in a region upstream of the collar section. The invention is characterized by the fact that the at least one axially extending channel is dimensioned in such a way that pressure medium may accumulate on the collar section. | 04-15-2010 |

20080230642 | Process and apparatus for defined comminution of polymers gels - An apparatus and process for defined comminution of polymer gels, wherein the apparatus includes a static cutting element in the form of a cutting screen. The cutting element is optionally supported, and has pretensioned wires, rods, fibers, wovens, stencils or profiles. Optionally, a dynamic cutting element is provided for shortening the gel strands or particles obtained by means of the static cutting unit. Also, a feed unit is provided for feeding the polymer gel to the static cutting element in a clamped-in, shape-stable state. The feeding of the gel is effected batchwise or continuously. | 09-25-2008 |
