Title: Variable-frequency pulse generator system - divides crystal oscillator frequency by input frequency setting and compares quotient in AND=gate with counter contents
Inventor: TRUONG THINH VAN ING GRAD
IPC: H03K23/66
Filed: 1978-12-30
Abstract: The pulse generator has a crystal oscillator whose output is divided by the input signals from the input keyboard. The resulting quotient is constantly compared by an AND-gate with the contents of a counter, driven by the crystal oscillator. The AND-gate output controls a flip-flop which converts it into rectangular pulses having the frequency entered via the keyboard. The crystal oscillator may have a frequency of 200 MHz, i.e. 200 times greater than the max. output frequency, in order to reduce the error introduced by neglecting the decimal places when the quotient is formed. The pulse generator operation provides rectangular voltage signals of any arbitrary frequency.

Patent DE-2901036-A1 (DE)
Title: Gas and air dehumidification - by vapour diffusion towards cooled surfaces to save power etc.
Inventor: FLEISCHER DIETER DIPL ING
IPC: B01D5/00
Filed: 1979-01-12
Abstract: The method is based on water vapour diffusion in the direction of the cooled surfaces which are adjoined by a layer of almost stationary air. This layer is achieved in practice by arranging the cooling surfaces horizontally and by lining them with gas-permeable material which keeps any fast flow away from the cooled surfaces, leaving adequate space for water condensation. The method avoids the waste of energy by having to cool the entire fluid below its dew point and utilising only a small part for water condensation. This saves both power and constructional expenditure.

Title: Welding parameter display system - removes noise interference through averaging by periodical integration
Inventor: PUSCHNER PETER DR ING
IPC: B23K9/10
Filed: 1979-04-30
Abstract: Welding parameters such as the current are displayed and recorded by integrating an output signal for given integration intervals. Each integration cycle is repeated and each result is stored until the next integrated value has become available. The averaged parameter is recorded or used directly for the control of the welding operation. This produces continuously reliable data for monitoring or controlling a welding operation. This deals with the strong noise content in all welding signals and removes subjective errors in reading fluctuating pointer indications.
