Title: Control of PWM signals in push=pull DC=AC converter
Inventor: HOUBEN MICHAEL
IPC: H02M3/337
Filed: 1994-06-23
Abstract: A method for controlling PWM signals in a push-pull DC-AC converter 14 has the PWM signal pulse frequency preset by a clock generator in a control module 24 and the pulse-width controlled by a main circuit 20, 22, 24 depending on the comparison between actual and required values of output voltage and/or current.

Title: Identification coding for containers
Inventor: MUELLER GOTTHARD
IPC: B65D23/14
Filed: 1994-11-08
Abstract: The container has at least one recess into which a transponder (2) placed. By using a HF field data is written into the transponder memory to be read by a similar HF field.

Title: X-ray image acquisition arrangement and x-ray detector
Inventor: SUZUKI MASAKAZU
IPC: G01N23/04
Filed: 1994-11-24
Abstract: The arrangement has an x-ray irradiation device for directing x-rays towards a region of an object, an image generator for detecting the x-ray image of the region and an image processor for reading the image from the image generator and for performing predefined image processing.
