Patent DE-3151005-A1 (DE)
Title: Gravure printing machine
Inventor: KOERNER FRIEDRICH
IPC: B41F35/02
Filed: 1981-12-23
Abstract: The invention relates to a gravure printing machine. Ink is applied to the gravure impression cylinder via an ink roller. The excess ink is scraped off by a squeegee. However, ink pigments usually accumulate in the edge region of the cylinder circumference, form solid lumps in the course of time and have to be removed if they have not previously been flung off in an uncontrolled manner. According to the invention, the accumulation of the ink pigments in the edge region of the cylinder circumference is prevented in that the edge regions are sprayed with the solvent contained in the printing ink. Due to this spraying, a continuous cleaning of the edge regions and also of the end faces of the cylinder can take place. The solvent correspondingly passes continuously into the ink trough, which is more favourable than the addition of relatively large quantities of solvent from time to time.

Patent DE-3222201-A1 (DE)
Title: Earth rod
Inventor: MEIER RUDOLF
IPC: H02B1/16
Filed: 1982-06-12
Abstract: The invention relates to an earth rod, which is assembled from a plurality of rod-shaped subelements (1), for dissipating electrical currents in which recesses (10, 11) are provided for connecting these subelements to one another, as well as pegs (3) which can be driven into these recesses. The pegs have a plurality of regions which lie one behind the other in the longitudinal direction of the subelement and are used as a mechanical press connection, the recesses being constructed to match them. While maintaining the required length of the pegs and the depth of the recesses, it is intended to reduce the effective closing movement and hence to make it possible for the earth rod to be driven correctly into even relatively soft ground. In addition, difficulties which previously arose as a result of deformed or torn material (so-called "fretting") should no longer occur. To this end, the peg regions (6, 7) have different diameters, the diameter of the region (6) closest to the base (9) of the peg being greater than the diameter of the region (7) behind it in the direction of the end (8) of the peg. <IMAGE>

Title: Device for the precise automatic counting of objects to be counted passing a gate or lock arrangement
Inventor: RICHTSCHEID ANTON DR ING
IPC: G07C9/00
Filed: 1983-01-20
Abstract: A device for the precise automatic counting of objects to be counted, with distinct height extent, passing a gate or lock arrangement, the counting being carried out wire- and contact-lessly, has at least two transmitter/receiver combinations, tuned to one another, as system components for simultaneously detecting the passing object to be counted at various measuring locations. At least one of the transmitter/receiver combinations is set by discrimination of the propagation conditions in such a manner that it only detects a predetermined, spatially limited section of the objects to be counted. The receivers, numbering at least two and detecting different measuring locations, of the transmitter/receiver combinations are logically combined by means of an AND circuit in such a manner that the detection signals emanating from the receivers are only used for the counting operation in the case of an AND statement. A counting device designed in this manner makes it advantageously possible operationally reliably to carry out self-monitored and absolutely precise single-counts of passing living beings and/or moving objects.
