IPC: G11B20/12
Filed: 1990-03-12
Abstract: In conventional recording processes, the digital data are recorded continuously from the beginning to the end of the track of the recording medium at a net data rate which is fixed in each case for the entire recording. The aim of the invention is to record and/or scan data on a recording medium with optional reading and writing access. Continuous recording of digital data is replaced by burstwise recording. As a result of the burstwise recording of the data, each burst forms a cluster on the record carrier. The data are preferably recorded in CD standard recording format at a data rate of 1.411 Mbits per second. Recording and reproducing of data on a re-recordable contactlessly scannable record carrier, for example a magneto-optical disk (MOD).

Title: Sediment removal from bottle, esp. for sparkling wine - has closed tube section in bottle neck to take liq. nitrogen@ or air coolant, to freeze sediment to a plug for removal
IPC: C12G1/08
Filed: 1991-03-13
Abstract: To remove the sediment from fermentation in bottles, where the bottles are head-down, it is frozen to form a plug for extn. by passing a coolant fluid into the bottle head by a feed tube. It is held away from the liquid in the bottle, so that the sediment is frozen from within into a removable plug. The coolant fluid is pref. liquid air or nitrogen. A tubular section is secured to the crown cork at the side towards the fluid within the bottle, closed at the inner end and open at the outer end, to take the coolant fluid, or the tube section is a cooling spiral for the coolant to flow through. The tube section has the shape of an inwards closed bowl, to take the coolant fluid delivered by a feed tube, and can be shaped as part of the crown cork. The feed tube for the coolant is inserted into the tubular section, and has axial openings distributed along its length for the coolant to flow against the inner surface of the tubular section. ADVANTAGE - The method gives a rapid freezing of the sediment into a plug, independent of the ambient temp., and without requiring additional appts.

Title: Dynamic compression process for X=ray diagnostic system
Inventor: MAACK HANNS-INGO
IPC: H04N1/407
Filed: 1991-07-05
Abstract: The X rays transmitted through a patient are received by a cylinder shaped drum that rotates about an axis and forms a 2D charge pattern on the surface. The signals may be detected by a sensor, amplified and digitised for input to an image processor.     The processor performs a sequence of operations to provide dynamic compression of the data.
