Abstract: A process for the treatment of spot-like zones in fabric webs or material strips of this type during a manufacturing process and a device for this are intended to make it possible to detect and, above all, locate defects easily, without the manufacturing process having to be interrupted as a result. For this, the spot-like zones are assigned marking plates prepared so as to be finish-resistant and having metal inserts, and these marking plates are connected to the fabric web in such a way that the metal insert spans a particular spot-like zone. The connection of the marking plate to the fabric web is to be made by means of an adhesive layer which is activated ultrasonically. The device has a marking plate (10) with a carrier disc (11) made of flexible and finish-resistant material as well as with a metal insert (12) which is covered, on the surface of the carrier disc facing the latter, with an adhesive layer (14). <IMAGE>

Title: Video recorder with improved recording of the audio signal
Inventor: KLUTH HANS-JUERGEN ING GRAD
IPC: H04N9/802
Filed: 1982-10-25
Abstract: A video recorder of the Video 2000 system switches to replay for a test time (13) of 1.5 lines during the recording for the purpose of scanning a control signal (9) for track position control. When a frequency-modulated audio carrier (11) is also recorded on the video signal track, this audio carrier has periodically repeated interruptions (28) during the replay. These are avoided by an increased angle ( alpha ) of wrap of the tape (20) around the head wheel (14) and by the audio channel being switched over (25) between the video heads (15, 16) in each case at the beginning of the test time. <IMAGE>

Patent DE-3246323-A1 (DE)
Title: Nickel bath
IPC: C25D3/12
Filed: 1982-12-15
Abstract: In some cases it is necessary to coat aluminium with nickel, the most difficult operating conditions probably being encountered in aluminium pistons in internal combustion engines. Adhesion problems are encountered, during further coating with other metals when known processes are employed. Satisfactory solutions are not obtained without intermediate activation. However, this solution is obtained by high proportions of nickel sulphate, small proportions of an acid which stabilises the pH, very small proportions of a fluoride which disintegrates the oxide layer produced in the lithium/cerium bath, a chloride which promotes the dissolution of the nickel anodes and a phosphite which improves the adhesion of the nickel layer. The solids in the bath are kept in suspension by vigorously circulating, for example, air. The particle size should preferably be 3 micrometers.

Patent DE-3307443-A1 (DE)
Title: Fault-protection circuit
Inventor: EICHHORN KARL-FR DR ING
IPC: H02H3/33
Filed: 1983-03-03
Abstract: A fault-protection circuit for circuits having fixed or variable frequencies and any desired current waveforms, especially for (domestic) electrical stimulators, having a summing current transformer whose primary windings are located in the operating circuit and whose secondary winding is supplied with AC frequency which is generated by an auxiliary generator. The secondary winding and an amplifier are connected in series with the auxiliary generator which generates the AC frequency, so that, if the summing current transformer is operated exclusively in the linear region and a fault occurs in the operating circuit, the fault impedance is copied on the secondary side. This leads to an increase in the centre-frequency current from the auxiliary generator, which is evaluated for tripping. Alternatively, the premagnetisation can be set by means of the centre-frequency auxiliary generator voltage such that the device operates in the saturation region of the transformer core, the operating-point displacement on the B-H characteristic in the event of an unbalanced fault occurring generating even-numbered harmonics, which are evaluated for tripping.
