Date Dec. 19, 1985.During ceramic casting for the production of a molten bath it is often observed that the fire-resistant material becomes eroded and/or solid oxide phases are deposited. Both phenomena interfere with the smooth outflow of the molten bath. The present invention is intended, therefore, to provide an outflow which is stable in shape even when a molten bath is passed through, especially in multiple-sequence casting. To this end, the invention provides for ceramic casting with an envelope (10, 14) which is at least partly external and an internal insert (11, 14, 53) at a distance from the envelope (10, 14), the insert ( b 11, 14, 53) and envelope being connected together.

Abstract: The iron comprises an electrically heated soleplate (3), the desired temperature of which is controlled by a thermostat (5) by the said thermostat periodically interrupting and restoring the power supply. The thermostat (5) can be set by means of an adjusting element (19). The iron is provided with a first and a second indicating element (23, 25), with in each case two indicating states (activated/non-activated). The indicating elements (23, 25) provide information on the actual temperature reached with respect to the desired temperature set. After turning the adjusting element (19), according to the invention the indicating state of the indicating elements (23, 25) is obtained from the turning direction of the adjusting element (19), from the operating state of the thermostat (5) before and after adjustment of the adjusting element (19) and from the old indicating state of the indicating elements (23, 25) before turning the adjusting element (19). As a result, an otherwise complex thermocouple, required in addition to the conventional thermostat (5), is not needed. <IMAGE>

Abstract: A method and a device are proposed for carrying out a value determination of the register difference on contours occurring in the printed image (for example letters in negative writing) by means of a colour video camera 2. The signal of the colour video camera 2 carrying the colour information is subjected to a colour separation in accordance with the printed colours occurring during printing. A contour, which has been produced by printing at least two printed colours on top of one another thus results in at least two separations in the corresponding printed colours. To determine the register difference, the offset from one part-image (separation) compared with the other part-image is now calculated. According to the device, a frame buffer 4, a colour separation computer 5, a colour separation memory 6 and an image computer 7 are provided in addition to a colour video camera 2.

Abstract: The invention relates to a method and apparatuses for thermal wave analysis, which is applied to measure geometrical, thermal, electronic and elastomechanical material parameters of solids, in particular of their surface layers. It is chiefly applied in coating technology. 
<??>The object of reducing the technical complexity and sensitivity limit of thermal wave analysis is achieved according to the invention when a single laser beam which has an additive two-frequency intensity modulation is directed onto the object and the amplitude of the mixed frequency of the discrete modulation frequencies that is not contained in the excitation beam is analysed as the response signal. An advantageous suppression of noise and reduction in the sensitivity limit are achieved through obtaining a reference signal from the excitation beam and forming its difference with the measured signal.

Abstract: A multi-memory apparatus, configured only with identical memory units with access to the common system bus, provides secure data identity in the event of various errors by using synchronous as well as parallel operation. A memory unit in a multi-memory apparatus includes a refresh request circuit, a bus control circuit, a bus-response circuit as well as a control circuit. A master refresh request circuit issues a memory-refresh request by using the bus clock and a backup refresh request circuit issues a memory-refresh request by a trigger from the master memory. A master bus control circuit responds to the system bus and a backup bus control circuit prohibits the unit from responding. A master bus-response control circuit allows the bus control circuit to respond to the system bus and changes mode between memory units from master/backup to backup/master in the event of an error detected in the master memory unit.
