Title: Regulating actual frequency of pulse chain - measuring phase position w.r.t. stipulated frequency and using resultant difference signal to maintain constant value
Inventor: BAADER UWE DR ING
IPC: H03L7/097
Filed: 1990-08-20
Abstract: The phase position of the pulse chain is measured and evaluated by converting the pulses in each chain in a signal cycle into constantly repeated voltage or time signals. Each voltage signal in each signal cycle has a climbing flank reaching a peak value followed by a fulling flank, one flank being steeper than the other. The gradient angle of the flatter flank has a certain relationship fuctor with the frequency of the pulse chain. The angle if inclinat-ion of the steeper flank is either alos related to the frequency yet at a higher factor or dependent on a predetermined time that is shorter than the climbing or falling time of the flatter flank. Comparison signals are derived from the voltage signals. USE/ADVANTAGE - Signal suitable for direct regulation of the actual frequency generated from comparison of the measured phase positions.

Patent DE-4036563-A1 (DE)
Inventor: BOLLMANN WERNER
IPC: B29C44/34
Filed: 1990-11-16
Abstract: 2.1 Foam articles are produced by allowing steam to act on the expandable polymer in a mould. In this case, the steam state is assumed to be invariable, and the steam treatment is controlled only in terms of time. If the steam state varies, the essential properties of the foam article change. With the novel process, foam articles of consistently high quality are obtained without using an excessive amount of steam. 2.2 In the case of the novel process, measuring of the flow rate (by means of a vortex-flow flowmeter), pressure and temperature of the steam is carried out. From this the amount of steam fed to the foaming apparatus at short time intervals is calculated. Subsequently, the duration of the individual phases of the steam treatment is altered - if appropriate fully automatically - in order that the foaming apparatus is fed the necessary amount of steam in each steam-treatment phase. 2.3 Production of foam articles from expandable polymers, for example from expandable polystyrene. <IMAGE>
