Abstract: The invention relates to the drying of veneer and similar products. It provides a solution to the problem of such products, after having passed through a hot air drier, exhibiting local areas having an intolerantly high moisture content--they are "underdried". According to the invention those areas are dried with microwave energy. The products (4) pass through the near field of the microwave energy present as standing waves in transverse ducts (6) also supplying the hot air and having openings (11) through which the microwave energy is tapped. Together they cover all of the adjacent product surface, but energy is only tapped through those of them past which underdried areas travel.

Abstract: The invention relates to a method for drying wooden products and solves the problem of providing such a method which is very economical and allows continuous control of the drying process. According to the invention the products are the moisture to migrate to the external surfaces of the products where it is absorbed by the air which is then dehumidified. The temperature and moisture content of the chamber atmosphere are continuously controlled.

Abstract: A marking device for thin wires, conductors and the like comprises two major portions. The first portion is of substantially arcuate cross-section and its inner wall extends along at least half the circumference of the thinnest wire on which the device may be mounted. The second portion, which is integral with the first one, consists of two flange-like projections extending radially outwards and interconnected at their outer ends. Their outer walls offer large areas for receiving symbols. When the device is mounted on a maximum diameter wire the arcuate portion and the projections are stretched to form a circular sleeve the inner wall of which contacts the wire along all of its circumference.
