Abstract: Reinforcing or carrier elements for plaster are used as electrodes in electro-osmotic dehumidification installations. The elements comprise a carrier body constituted by a flexible net having a surface of synthetic resin in contact with the plaster and the net has filamentary carrier materials incorporated therein. The synthetic resin is a conductive, essentially ion-free thermosetting resin of macromolecular structure, preferably an at least partially cross-linked acrylate polymer having a high surface roughness and containing a small amount of a plasticizer, and forms either the matrix or a coating of the flexible net. The filamentary carrier materials may be carbon or metal filaments. In the use of the dehumidification installation, a voltage alternating between a positive and a negative potential is conducted between the cathode and the anode, the time interval of the positive potential exceeding that of the negative potential.

Abstract: A monolithically integrated component generates an alarm signal which exhibits a desired pulse program. The element contains at least one frequency divider and a logic circuit generating the pulse program. The input signal is a pulse-shaped clock signal which is produced in the electrodynamic resonator of the clock mechanism or in an additional oscillator circuit of the component. The monolithically integrated component only contains four terminals and can therefore be accommodated in commercially available (plastic) forms of housings.

Date Jun. 15, 1989.An optical system for laser marking, such as for engraving marks such as numbers and dates on surfaces, and exhibiting improved efficiency and improved quality of the resulting mark. The optical system includes a focusing system, such as a lens, and a concave mirror situated between the laser and the mask with its vertex at the focal point of the focusing system and its reflecting surface facing the mask. An inlet opening in the concave mirror is formed about the vertex, and the transverse measurement of the inlet opening is slightly larger than the transverse measurement of the focal point. The mask is formed as a mirror, preferably a plane mirror, with the reflecting surface facing the concave mirror, and the radius of curvature of the concave mirror is longer than twice the distance between the mask and the concave mirror. In operation, the portion of the laser beam radiated through the mask is increased because the portion thereof not passing directly through the mask openings is reflected by the mirror face of the mask back to the concave mirror, which in turn reflects the light back to the mask, such that additional portions of the laser beam pass through the mask openings. The size of the reflecting surface of the concave mirror and consequently the amount of the light reflected by the concave mirror are optimized by the laser beam being focused by the focusing system in the small opening in the vertex of the mirror.
