摘要： Disclosed is a brake booster for motor vehicles, the control valve (12) of which is operable, irrespective of an actuating rod (7) that displaces a valve piston (9), via an electromagnet (20), which actuates a third sealing seat (24) allowing ventilation of the working chamber (3). The third sealing seat (24) is provided on a sleeve (32) that cooperates with the electromagnet (20), and a ring (36) is arranged, which is displaceable in relation to the third sealing seat (24) and is supported on the sleeve (32) by the intermediary of an elastic or compressible element (37). In order to improve the dynamics and the sound behavior of the brake booster, the ring (36) is arranged radially within the sleeve (32) in such a manner that its areas (33), by which it is in contact with the valve body (10), at least partly release the passages (19) provided in the valve body (10).

摘要： The invention relates to a method permitting the magnetic properties of ferromagnetic powders which are used for the preparation of heavy media for the float-sink dressing of minerals, to be tested. To this end, the invention provides for the ferromagnetic powder to be magnetized in a magnetic steady field at a field strength within the range 600 to 1000 amperes per cm and the magnetized ferromagnetic powder to be demagnetized in a cyclicly decreasing magnetic alternating field at a field strength within the range 1000 to 1500 amperes per cm. Next, the ferromagnetic powder so pretreated is heaped up, in the center portion of a circular plate made from dielectric material and the circular plate is placed on an iron core-provided coil. An alternating current voltage of 180 to 260 volts is applied to the coil, thereby effecting the occurrence of alternating fields of 180 to 220 amperes per cm in the center portion of the circular plate. The ferromagnetic powder heaped up is observed for the figure it is forming under the influence of the alternating fields. The formation of a closed figure around the center portion of the plate indicates unlimited qualification of the ferromagnetic powder for use in a heavy medium suspension.

摘要： The invention relates to a method permitting ferromagnetic powders for use in heavy medium suspensions for the float-sink dressing of minerals to be readily tested as to their efficiency in magnetic separation and demagnetization. To this end, the invention provides(a) for a heavy medium suspension specimen to be removed from the purification cycle directly downstream of the magnetic separation stage, for it to be freed from impurities by decantation, and its relative sedimentation velocity to be determined with the aid of a sedimentometer;(b) for a heavy medium suspension specimen to be removed from the purification cycle downstream of the demagnetization stage, for it to be freed from impurities by decantation, and for its relative sedimentation velocity to be determined with the aid of a sedimentometer; and(c) for the heavy medium suspension specimen according to (b) to be demagnetized in a cyclicly decreasing magnetic alternating field with a maximum field strength which is 1.1 to 1.5 times the maximum field strength of the magnetic separator, and for the relative sedimentation velocity of the specimen to be determined with the aid of sedimentometer. The ferromagnetic powder is reliably separable magnetically and demagnetizable with the aid of a demagnetizing means in the event of the relative sedimentation velocity according to (a) being at least ten times greater than the relative sedimentation velocity according to (c), and the relative sedimentation velocity according to (c) being at most 10% lower than that according to (b).

摘要： The radial pump preferably for use in connection with a hydraulic clamping device includes a plurality of pumping elements enclosed in a housing and cooperating with a corresponding pluraity of discharge valves. A multiway control valve controls the delivery of pressure fluid to a load port in such a manner that during the actuation of the load the outlet of all discharge valves are united to deliver the entire flow of pressure fluid into the load port, whereas when the load is maintained under a constant pressure, only one pumping element delivers discharged fluid via a single discharge valve into the load port and the remaining pumping elements deliver their output into the reservoir.

摘要： The present invention discloses a brake force booster for automotive vehicles having a control valve which is operable independently of an actuating rod displacing a valve piston, by way of an electromagnet which actuates a third sealing seat. Displacement of the sealing seat in opposition to the actuating direction of the brake force booster permits ventilating the working chamber. To eliminate all pneumatically induced force components in an independent activation, according to the present invention, a permanent pneumatic connection is provided between a pneumatic chamber delimited in the control housing by the valve member and the vacuum chamber, and in that both a second sealing seat which is provided on the valve piston and used to ventilate the working chamber, the third sealing seat, and the valve member in its sealing lip delimiting the pneumatic chamber in the control housing have almost identical diameters.

摘要： For filling and adjusting double-membrane cassettes acting as link members in piston metering pumps, the sealing surfaces of the membranes are first coated with a resilient pressure-deformable cement. The membrane cassette is introduced still unclosed into a thermostat where an adjustable, uniform pressure is applied to the upper membrane. The membrane cassette is then filled under an excess pressure of from 0.2 to 1 atm. and closed. After closing, the membranes of the cassette are brought into plane-parallel alignment in an evacuation unit.
