Patent NL-7208356-A (NL)
IPC: H04N7/34
Filed: 1972-06-19
Abstract: This disclosure relates to real time, all digital, video receivers wherein a linear light modulation is achieved by means of a "half-tone process." The half-tone process is effected by gating a linearly scanned electron beam with constant amplitude, variable duty cycle pulses. The duty cycle is varied in successive Nyquist intervals in a manner directly related to the binary digit content of the successive n-bit words of a received pulse code modulated (PCM) video signal. For a 7-bit conventional PCM video signal, for example, 128 different levels of light intensity can be provided for each Nyquist interval.

Title: Flow limiting valve for pipe line - uses sudden fall in downstream pressure to cause valve closure
IPC: F16K17/30
Filed: 1976-03-31
Abstract: The flow limiting valve has a cylindrical body (1) with top and bottom flanges. The valve head (6) is attached to the valve rod (4) which slided in the guide bush (5).
