Title: Roughening of surface of aluminium@ foil - in which etching tunnels are formed
Inventor: FEILHAUER RUDOLF DIPL ING DR
IPC: C23F1/20
Filed: 1992-09-29
Abstract: Thermally treated aluminium foil is electrolytically and/or chemically roughened using an etching bath containing chloride ions and passivating components. During the process, etching tunnels are formed, and, after an intermediate rinse, these tunnels are widened by electrolytic and/or chemical etching in a further bath. The etching bath contains one or more passivating components of concentration greater than 0-5N. The components are chosen from sulphuric, oxalic, tartaric or phosphoric acids, pref. 2-10N sulphuric acid. Prior to this treatment the foil is treated in an aqueous, halide-free bath as the anode, followed by treatment in a chloride ion-contg. bath which does not contain passivating components. USE/ADVANTAGE - Treating aluminium foil to be used in high voltage, electrolytic capacitors. During the etching process the tunnel formation arises from nuclei in the oxide layer. The oxide layer free from nuclei remains in place, and acts as a protective layer for the aluminium.

Patent DE-4306524-A1 (DE)
Title: Device for pressure-dependent speed regulation in drilling and screwing machines
Inventor: BROCKMANN PETER
IPC: B25B23/14
Filed: 1993-03-03
Abstract: The switching on and off and also the speed/torque of a machine are controlled and regulated pressure-dependently. The device can be used on stationary or movable machines. In conventional machines, the screwing attachment can slip off and damage screw and screwing attachment, on account of incorrect speed or inappropriate pressure. Further, the rotation of the machine starts only after the drive has been manually switched on. To remedy this, the device which controls and regulates the drive pressure-dependently is built onto or into the machine. The drive is switched on only when there is sufficient pressure on, for example, a screw. If the pressure increases during the screwing operation, the speed and torque also increase. This has the advantage that damage to, for example, screw and screwing device is prevented. The screwing operation itself is facilitated since, through such a device, the screwing begins automatically and furthermore the screwing operation is interrupted if, owing to insufficient pressure on the screw, the screwing attachment slips off. Figures 1 and 2 show the principal steps in the use of the device and the effect of sensory analysis and regulation on the drive of a machines, respectively. <IMAGE>

Title: Method for reproducing a single-channel or multiple-channel digital, block-by-block-coded audio signal
Inventor: THEILE GUENTHER
IPC: H04H20/00
Filed: 1993-03-15
Abstract: In order to achieve a variable dynamic range in the reproduction of a single-channel or multiple-channel digital, block-by-block-coded audio signal at low cost, the scaling factors separated from the audio signal are modified prior to their use for level control according to dynamic requirements. The scaling factors in each case classify the peak value of the digital sample values within a specific time interval (block) and control block-by-block the level of the digital audio signal to be reproduced.

Title: Flexible optical sorting of hollow bodies
Inventor: MASSEN ROBERT PROF DR ING
IPC: B07C5/34
Filed: 1993-06-20
Abstract: The invention relates to a flexible system for the sorting of hollow bodies. The hollow bodies, which are individualised on a conveyor belt and transported without slip, first pass a station having image-transmitting sensors from which, using methods of image processing, shape features and colour features are derived, as are the presence of printing, closure caps and jars. The separation of glass and plastic is carried out using the common evaluation of shape signals and the weight determined by means of a balance. The material types are determined using non-contacting infrared, microwave or X-ray sensors, whose measuring field is deflected by the image processing to locations not disturbed by printing. The hollow bodies are moved on the belt in a slip-free manner and are sorted out by a series of sorting switches into containers, the sorting criteria being established flexibly by the user from the measured sensor signals and being assigned in each case to a sorting station.

Title: Process for producing press fittings, and apparatus for carrying out the process
Inventor: VIEGENER WALTER
IPC: B21D17/02
Filed: 1993-10-23
Abstract: The process for producing press fittings from plastically deformable material comprises essentially three process steps. In the first process step, a correspondingly prefabricated blank is inserted into a die and, if appropriate, cut to length. In a second process step, the blank is upset within the die to such an extent that the wall of the blank buckles in the region of annular grooves provided in the die. In a third process step, the pre-upset and buckled wall sections are rolled to the correct dimensions using a roller introduced in the press fitting. A apparatus provided for carrying out this process exhibits a corresponding die and a mandrel which is introduced into the blank and prevents a narrowing of the cross-section of the blank during subsequent upsetting. The upsetting is carried out by means of a sleeve which runs on the preliminary mandrel and presses the blank into the die. The dimensionally accurate forming of the beads on the press fitting is carried out by an excentrically guided roller.
