Patent DE-4102983-A1 (DE)
Inventor: SERMUND GERALD
IPC: B21B27/00
Filed: 1991-02-01
Abstract: The surface structure is generated on a roller (2) designed for application to a material. The roller (2) has recesses (22) produced by an electron beam (3) and consisting of depressions and crater walls (62) surrounding them. The recesses (22) are arranged in a two-dimensional grid with a constant grid structure. The grid consists of substantially mutually parallel rows of recesses (65) and the recesses (22) in neighbouring rows (65) are mutually staggered. The recesses overlap at least in the direction of the row or in a direction running transversely thereto and thus form a quasi-stochastic grid. In the process for producing the surface structure, a grid formed by the recesses with a constant grid structure is produced by the electron beam in the region of the roller surface. The partly overlapping arrangement of the recesses produce a pseudo-stochastic three-dimensional surface contour.

Title: Biological air cleaner - uses preheated water for air washer to keep microorganisms active during all seasons
Inventor: DETZER RUEDIGER
IPC: B01D53/85
Filed: 1991-04-29
Abstract: In the operation of a biological air cleaner, where microorganisms lie on a carrier after an air humidifier esp. a spiral twist washer, the water for the air washer is preheated so that the dry thermometer temp. of the air leaving the washer does not drop below a given value pref. of +10 deg.
