Patent DE-3201848-A1 (DE)
Inventor: DUDLI ANDREAS
IPC: C02F3/08
Filed: 1982-01-22
Abstract: With contactor bodies formed of spirally wound up corrugated panels providing ducts in the region of the corrugation profiles which are alternately filled with waste water and air, there is a problem to completely fill the ducts and to provide a continuous flow through the ducts in a body of simple and rigid construction. In order to solve this problem, the corrugation profiles of at least one corrugated panel (3', 3'') are inclined at a predetermined angle relative to the axis (XX) of the contactor body. Thereby, the disadvantages of the known, mechanically unstable constructions comprising a tube bundle are avoided and an intensive flow of waste water and air within the ducts is achieved. Advantageously, the corrugation profiles of winding layers arranged radially above each other or axially beneath each other comprise different inclination angles (a', a''), especially angles which are opened contrary to each other.

Title: Maintenance-free weather protection and wind sealing cover for old and new windows with sealed joints
Inventor: SCHWEGLER ALOIS DIPL ING
IPC: E06B3/30
Filed: 1982-01-22
Abstract: Summary of the patent application for a maintenance-free weather protection and wind sealing cover for old and new windows, with sealed joints. The window case and its window frame are to be covered with a weather protection cover with a sealing strip so as thus to ensure protection against any weather conditions. The cover material is made of metal coated with aluminium, plastic, asbestos or glass fibre reinforced concrete or of profiled wood. The cover is connected to the glass window-pane using a PVC sealing strip with a flexible lip. By widening the PVC receiving groove, the window case like the window frame can be provided with full heat protection or with soundproofing. Where fixed roller shutters are mounted, only a slight weak insulation can be achieved on the window case, a full insulation of the glass frame being possible however. Roller shutters which are mounted subsequently can be fully insulated. The construction is such that full ventilation is ensured. The protection cover makes it possible for the metal/plastic windows to be fully insulated. This thus results in a full protection against wind and weather. The visible surface can be treated as desired depending on the cover material. The cover can be mounted even by a non-specialist.

Title: Pneumatic operating element having a membrane piston
Inventor: HOFFMANN RUEDIGER
IPC: F15B15/10
Filed: 1982-11-26
Abstract: The invention relates to a pneumatic operating element having a membrane piston, whose housing is split, transversely to the direction of the stroke, into two housing halves which in each case extend approximately over half the piston stroke. At their connecting point, the housing halves overlap over the complete circumference, such that they enclose the membrane axially between them in a sealed manner and subject to pretensioning. Provided on the outer edge of the membrane is a bead-like thickening which is held in a corresponding annular recess in the housing halves. In order to be able to achieve a piston force which is as high as possible for a predetermined structural volume and predetermined operating pressure, the axial extent of the overlapping region and the clamping-in length of the membrane therein are designed to be as long as possible, that is to say they correspond to approximately half the piston stroke. In consequence, the connection of the housing halves and the clamping-in point of the membrane can be constructed to be particularly narrow, radially.
