Patent DE-3106271-A1 (DE)
Title: Electrically heated air humidifier
Inventor: GUENTHER ALFONS
IPC: F24F6/02
Filed: 1981-02-20
Abstract: In an electrically heated air humidifier, a water tank (3) is used, from which, through a small outlet opening (6) present in its closure cover (5), water runs out slowly into a trough (1), on the trough bottom (7) of which the electric heating plate (8) lies. A relatively thin water layer is formed, from which the water evaporates or vaporises. This water layer also closes the outflow opening (6) of the water tank (3) so that no air can penetrate into the interior of the tank (3) and equilibrium is achieved between the hydrostatic inner pressure and the atmospheric outer pressure, which prevents continued flowing of water from the tank (3) for as long as the outflow opening (6) is closed against air access by the water layer in the trough (1). As a result, a constant very low height (H) is maintained so that, in comparison with the tank content, only a small quantity of water constantly has to be heated until it evaporates or vaporises. Therefore, only a low heating capacity is required. <IMAGE>

Title: Optical frequency generator
Inventor: FRENK HELMUTH DR
IPC: H03M1/00
Filed: 1981-03-26
Abstract: Optical frequency generator for application as a tachometer generator and rotation direction sensor and as an incremental phase-angle sensor. Problem: the aim is to avoid signal dropouts and phase errors in the 90 DEG  rectangular signals due to temperature, ageing and mechanical inaccuracies, and the amplitude drops by means of as simple a formation as possible of photocell signals which are suitable for push-pull input. Solution: (Fig. 1) optical imaging of a grid period onto three photocells or a plurality of periods onto three phase-shifted subgrids upstream of the photocells. In the case of four-quadrant cells, two opposite subcells serve as "middle cell". 0 DEG signal through two outer cells onto a push-pull input. The 90 DEG  signal is formed, and simultaneously freed from phase errors, by summing the outer signals and using them in push-pull operation relative to the average signal. An additional advantage is a larger spacing between rotating grid and fixed parts. <IMAGE>
