The distance between the plates on opposing drums is equal to the thickness of the circuit board plus the height of the components and any projections on the soldered side of the board. The distance between opposing striker elements of the drums is equal to the thickness of the board plus a small tolerance. The speed of the board is controlled by the rotational speed of the drum (6). Two further drums may be used, with the positions of the striker elements reversed w.r.t. the drums (5,6). The striker elements are rectangular in shape and have a concn. of mass and a saw-toothed configuration at their outer ends.

Patent DE-4442012-C1 (DE)
Inventor: HUMS ERICH DIPL CHEM DR
IPC: B01J29/06
Filed: 1994-11-28
Granted: 1996-08-29
Abstract: The selective catalytic reduction method has been adopted world-wide to decompose nitrogen oxides contained in flue gas. In this process, nitrogen oxides are contacted with a catalyst together with a reducing agent, mostly ammonia, and react into nitrogen and water. Because ammonia is difficult to handle, the storage, supply and dosage of ammonia are particularly complex. In order to achieve a high reaction rate, the invention provides for nitrogen oxides to be contacted with a catalyst at a temperature from 100 to 800  DEG C. The catalyst contains as catalytic components an aluminium silicate with a stratified structure, in particular mica. Transition metal ions, preferably lanthanum and/or cerium, are incorporated into the silicate grid. In this type of catalyst, nitrogen oxides decompose in the absence of a reducing agent. In addition, the nitrogen oxide decomposition rate is not adversely affected by the oxygen contained in the flue gas. In the temperature range from 200 to 600  DEG C, decomposition rates higher than 70 % were obtained with this catalyst. Catalysts according to the invention can replace state-of-the-art catalysts that work with a reducing agent to reduce the nitrogen oxide content of waste gas, for example for scrubbing flue gas or waste gas from power stations or internal combustion engines.

The seal between the upper side of the frame and the window frame is such that such a displacement of the frame produces a ventilation gap (12) between the frame and the window frame. The displacement is between 1.0 and 2.0 cm. The sealing device work in conjunction with a surface extending from the window frame vertically to the movement direction of the frame. The sealing devices comprise brush components.
