Patent DE-3102374-A1 (DE)
Title: Antireflection treatment of films
Inventor: KNOLL PETER DR
IPC: B24B31/00
Filed: 1981-01-24
Abstract: A process is proposed which serves for roughening surfaces of polyester films. The polyester film is covered with quartz sand or corundum powder of a defined grain size and vibrated, for example on a vibrating table. The degree of roughening can be varied by the choice of a suitable grain size and by the duration of the vibration. The polyester films are used in particular as polariser films for LCD displays. The roughening prevents reflection of the displays, so that they can be read more easily. The antireflection treatment of finished displays is also possible in this manner.

Title: Free-flow valve or regulator
Inventor: DUNGS KARL
IPC: F16K1/44
Filed: 1981-02-24
Abstract: The invention relates to a valve or regulator based on the free-flow principle. The valve or regulator has a movable valve plate which, when the valve is open, is located outside an approximately straight flow passage which opens into the valve seating area. In order to achieve a significantly higher flowrate without changing the overall size and pressure drop and, in addition, a flowrate/lift ratio which rises more rapidly in the initial stage of opening, two valve plates which can be moved jointly, two valve seats, situated a distance apart, and two flow passages parallel to one another are accommodated in the same housing. In the open position one valve plate is in the lee of the housing and the other valve plate is in the lee of a central web which carries one part of the two valve seats. <IMAGE>

Title: Ribbed component, whose ribs are formed by bends in sheet metal which are pressed together
Inventor: LINHARDT PETER
IPC: F28F3/04
Filed: 1982-12-09
Abstract: The invention relates to ribbed components of sheet metal, whose rib parts have been produced until now with open or with closed ribs. The object of the invention is to reduce the stringent demands in the technological production methods used in rib manufacture, to be precise to create a rib shape in which sealing creates no problems and in which the moulding force which has to be applied to press the rib walls together in the case of the closed ribs is low. The invention consists in that the rib walls touch only at the rib root in the region of the rib ends over the entire rib height and in the intermediate zone. The ribbed component can advantageously be used for the production of cooling vessels for transformers, of housings for electrical rotating machines, and of various heat exchangers.
