Title: Driving and idling rolls for straightening curved billet - at exit end of guide and support roll track of continuous casting plant
Inventor: GROTHE HORST
IPC: B22D11/128
Filed: 1979-09-28
Abstract: The cast billet leaving a mould travels through a curved guide and support roll track, and must then be straightened. Straightening is achieved using pairs of idling rolls, rotating on horizontal axes while the billet is driven by pairs of rolls rotating on vertical or inclined axes; rolls are driven at an adjustable speed, and are in contact with the edges of the cast billet. Each pair of rolls is pref. driven via a common gearbox and universal shafts. The straightening force is applied by rolls which must be large when the cast billet has a large cross-section.

Title: Sound-emission locator and analyser for non-destructive testing - has test head containing acousto-electric transducers to determine direction of incident sound pulses
Inventor: CROSTACK HORST-ARTUR DR
IPC: G01S5/22
Filed: 1980-09-10
Abstract: The position of the sound sourceis determined from the arrival of sound pulses at different measurement points. The moment in time when a pulse or pulse-like feature arrives at each of three or more adjacent sections (1) within each measurement point is measured, The differences in the times of arrival at the three sections are formed and used to find the direction from which the sound is approaching the place of measurement. The position of the sound source is determined from this direction and from a knowledge of the positional coordinates of the measurement point. Frequency analysis or an analysis correlating directly with the direction of the sound is performed at each measurement point. The signals are filtered or analysed before then are digitised. The measurement point is defined by a test head. The sections consist of transducers within the head. Several such heads may be attached to the component under examination. The outputs of the transducers are amplified (2), digitised (3), the pulses counted (5), and the counts passed to a microprocessor (6). The system handles sound of unknown speed, rapid pulse repetition rate, high noise levels and long transit times.

Title: Prepn. of hydrogen required for hydrogenation of coal - by supercritical extn. of hot separator sludge and gasification of residue
Inventor: DOLKEMEYER WILFR DIPL ING
IPC: C01B3/00
Filed: 1980-10-01
Abstract: In the catalytic hydrogenation of coal in oil suspension, hydrogen needed is made as follows from sludge in the prod. hot separator. The sludge is supercritically extracted with a C3-C10 (about) hydrocarbon. The extn. residue is gasified conventionally by endothermic and exothermic gasifying agents to H2, CO and CO2. The CO is then catalytically converted conventionally by water vapour to give more H2, which is sepd. The extn. may be preceded by vacuum distn. to remove more distillate oil. The amt. of coal required to produce the necessary H2 by gasification is reduced. The processing of the sludge is simpler and more economic than others used (e.g. centrifuging and pyrolysis, or coking in presence of H2).
