Patent DE-4135465-A1 (DE)
Inventor: SCHROECK PETER DIPL ING
IPC: B30B7/04
Filed: 1991-10-28
Abstract: In a radial press with a press spindle (A), a plurality of external control surfaces (1, 2, 3, 4) at an angle to one another are arranged in groups in two press yokes (18, 19) which are driven radially in relation to one another. The planes of symmetry of the control surfaces (1, 2 or 3, 4) which are arranged in the same press yoke extend parallel to the direction of drive. A plurality of external control bodies (31), which are situated between two of the external control surfaces in each case, are used for the radial advancing of pressing jaws (30) towards the press spindle. Internal control bodies (37) with further pressing jaws (41) are driven synchronously by the external control bodies (31). To reduce weight and size, one press yoke (18) is guided in relation to the other press yoke (19) by tie rods (25, 26), which penetrate the leading press yoke (19) on its ends situated outside the control surfaces (1, 2, 3, 4), are fixedly connected to the other guided press yoke (18) in each case and are connected on the opposite side of the leading press yoke to a pulling drive (52) which is preferably designed as a dedicated hydraulic drive (47/51, 48/50) which is assigned to each tie rod (25, 26). <IMAGE>

Inventor: MUELLER HANS
IPC: E03F3/06
Filed: 1992-03-06
Abstract: An underground main sewage pipe (12) is connected to a house by a branch pipe (2).

Title: Vacuum drying process with pure gas supply - to avoid stationary evapn. equilibrium conditions
Inventor: KRAEMER HANS-JOACHIM DIPL CHEM
IPC: B29C37/00
Filed: 1992-04-14
Abstract: A vacuum drying process is optimised by supplying fresh gas (pure gas or gas mixt. in which the partial vapour pressure of the liq. to be evaporated is below the equilibrium partial pressure under the prevailing drying conditions) into the drying chamber while maintained defined conditions of gas compsn., gas vol./unit time, pressure, temp. and time-variable vacuum. When e.g. acetonitrile-contg. liquids are being evaporated by drying at room temp. and 0.05 Pa vacuum, a supply of ultra-pure nitrogen, contg. no partial pressure of acetonitrile, is provided. The vacuum pumps must produce a much higher vacuum than the drying pressure, when the fresh gas supply is shut off, so that a sufficient amt. of fresh gas can be supplied to attain the drying pressure without too great a redn. in the vacuum. ADVANTAGE - The drying process is optimised w.r.t. time and quality and the materials are given more protection against losses, which is important in micro-analytical processes.
