Patent number: 7909262Abstract: According to one embodiment of the invention, a control valve for regulating temperature comprises a conduit, a fluid limiter, a restoring actuator, an opening actuator, and a restoring actuator chamber. The conduit has an inlet, an outlet, and an opening between the inlet and the outlet. The inlet is operable to receive fluid into the conduit and the outlet is operable to dispense of fluid out of the conduit. The fluid limiter is operable to at least partially cover the opening and thereby resist flow of fluid through the opening. The restoring actuator is operable to provide a force that moves the fluid limiter toward the opening to resist flow of fluid through the opening. The opening actuator is operable to provide a second force that moves the fluid limiter away from the opening to allow the flow of fluid through the opening. The opening actuator is activated based on a temperature of fluid in the conduit.Type: GrantFiled: December 13, 2007Date of Patent: March 22, 2011Assignee: Flow Design, Inc.Inventors: Fritz Eβfeld, Bernhard Henke, Karl-Heinz Brinkmann, John M. Trantham

Patent number: 4607797Abstract: A method and apparatus for pulverizing polymers. The apparatus comprises a hollow barrel within which at least one screw rotates. The interior of the hollow barrel is divided into a plurality of zones. Heating members are associated with a first of these zones and cooling members are associated with at least a second of these zones. Pre-crushing and pulverizing members are also disposed in said second zone. In the method, polymeric material is fed into the first zone of the hollow barrel and is fused therein. The fused material is then conveyed into the second zone wherein it is cooled, pre-crushed and pulverized. The powdered polymeric material is then discharged from said second zone. The method can therefore be effected continuously in a single apparatus.Type: GrantFiled: September 7, 1984Date of Patent: August 26, 1986Assignees: NPO Norplast, Hermann Berstorff Maschinenbau GmbHInventors: Nikolai S. Enikolopow, Stanislaw A. Wolfson, Anatolie I. Nepomnjaschtschie, Wadim G. Nikolskie, Wiktor A. Teleschow, Lidia A. Filmakowa, Heinz Brinkmann, Eckart Pantzer, Eberhard Uhland

Patent number: 4456308Abstract: A brake-drum flange is bolted to a wheel disk by an interface surface structure which limits the engagement area and avoids contact around the fastening bolts. In the case of a twin-wheel configuration, the two wheels are placed back-to-back, whereby the contact area has larger diameters than the contact areas between the brake drum and the one-wheel disk.Type: GrantFiled: September 29, 1982Date of Patent: June 26, 1984Assignee: Mannesmann AGInventors: Paul Opel, Klaus Herbst, Heinz Brinkmann, Albrecht Luders, Hans P. Wolsdorf

Patent number: 4416543Abstract: Apparatus for treating powdery rubber mixtures to form processed intermediate products comprises volumetric metering means; a filling extruder; a mixing and plasticizing portion located at the downstream end of the filling extruder and having a central toothed spindle, toothed planetary spindles and an internally toothed housing; and forming out means shown as an extruder cascade connected to the mixing and plasticizing portion and extruding material through a perforated plate with cutting blades. The mixing and plasticizing portion is of only short length and can effect intensive working but does so for only a short period of time on the material passing therethrough so that the material is not damaged by being over-heated.Type: GrantFiled: September 1, 1981Date of Patent: November 22, 1983Assignee: Hermann Berstorff Maschinenbau GmbHInventor: Heinz Brinkmann

Patent number: 4415268Abstract: A temperable screw casing for a twin screw extruder for processing plastics comprises a supporting member and wear resistant liner disposed therein. The liner has a spectacle shaped bore accommodating both screws of the extruder. The supporting member, which engages around the liner, takes over the reinforcing function of the screw casing. Low technical manufacturing cost and satisfactory tempering of the screw casing is achieved by providing the liner with a circular external cross section, surrounded by a supporting member which has a circular internal recess. Axial tempering holes are provided in wedge shaped projections which extend into the spectacle shaped bore of the liner. Axial tempering holes are disposed opposite one another in the supporting member, at the sides of the spectacle shaped bore of the liner. These result in individual tempering systems, by which the liner and supporting member can be tempered independently.Type: GrantFiled: June 10, 1981Date of Patent: November 15, 1983Assignee: Hermann Berstorff Maschinenbau GmbHInventors: Heinz Brinkmann, Siegfried Chszaniecki

Patent number: 4176967Abstract: Apparatus for the preparation and extrusion of plastics material or rubber, comprising a planet rolling extruder and a feed portion disposed upstream thereof with a main shaft of the planet rolling extruder being surrounded by planet shafts and being driven jointly with a feed-screw of the feed portion, in which some of the planet shafts at their ends adjacent the feed-screw are reduced in section to form transfer shaft portions and thereby receiving chambers for material fed to the planet rolling extruder by the feed portion. The transfer shaft portions may be cylindrical with a diameter smaller than the diameter of the root circle of the planet shaft gearing or may have, adjacent the feed-screw, a diameter smaller than the root circle of the planet shaft gearing and increase in diameter in a direction away from the feed-screw until they achieve the full shaft outline.Type: GrantFiled: June 8, 1978Date of Patent: December 4, 1979Assignee: Hermann Berstorff Maschinenbau GmbHInventors: Heinz Brinkmann, Horst Spielhoff
