Title: Method and device for displaying signal curves on a screen or on a recorder
Inventor: MEYER WOLFRAM ING GRAD
IPC: G01R13/20
Filed: 1981-11-02
Abstract: In certain recording methods, signal curves are to be sampled in time, digitised and temporarily stored in buffers. The problem exists of regenerating an analog curve with accurate values after reconversion of the digital values. The reconverted samples are usually averaged by filtering so that a high sampling frequency would be necessary for a sufficiently accurate representation of the values. According to the invention, the digitised signal values are reconverted into such a quasi-analog signal which represents the accurate value of the stored sample for each sampling time and represents the intermediate areas between the samples. In a device for carrying out the method, the buffer (2, 22) is associated with a unit (3-7, 23-27) for forming an excessive difference value, a subsequent filter ensuring that the curve passes accurately through the values of the stored digital values. <IMAGE>
Patent DE-3148034-A1 (DE)
Title: Pressure vessel with removable lid
Inventor: JASPER JOSEF
IPC: F16J13/24
Filed: 1981-12-04
Abstract: The invention relates to a pressure vessel with a removable lid. At its lid-side edge, the pressure vessel has a seating collar. At its edge, the lid is provided with a flange which is matched to the seating collar. The seating collar and the lid flange are surrounded by a clip of U-shaped cross-section. One leg of the U of the clip reaches under the seating collar. With the other leg of the U, it rests on the lid flange. It can be clamped by means of a hydraulic or mechanical clamping device. On the seating collar and/or on the lid flange there is an encircling positive engagement groove. The associated leg of the clip engages in this with a projecting, encircling positive engagement rib. The clip has an opening in the U which is larger by more than the height of the positive engagement rib than the thickness of the seating collar plus the lid flange. On the inside of the lid flange and/or seating collar there is a sealing apron. The arrangement is such that the sealing apron seals the gap which forms between the lid flange and the seating collar under the influence of the internal pressure in the vessel. The result is that the seal formed by the interaction of the seating collar, the lid flange and the clip can only be released when there is no longer an excess pressure in the vessel. It is simultaneously ensured that the vessel can only be pressurised when the lid seal has been properly closed. <IMAGE>
