Title: Fault-locating system for digital transmissions - sends commands by phase modulated sync. signal with given frequency
Inventor: HAMMER GERHARD DIPL ING
IPC: H04B17/40
Filed: 1979-01-19
Abstract: The fault-locating system sends commands to construct test loops in a digital line section, containing regenerators with low pass phase transmission characteristics. The testing end station sends a command by phase modulating the transmission sync. signal with a frequency lower than the cut-off frequency of the phase transmission characteristics of the series circuit of regenerators. At the other end station the power spectrum of the phase is checked and, if found to exceed a given level at the modulating frequency, a command is released. Detectors (ES) in the regenerators (ZS) receive the commands to construct test loops. The detectors consist of phase locked loops and discriminators.

Title: Plastic insulated cable core stranding - with deflecting rollers before stranding nipple
Inventor: AHLVERS DIETER
IPC: H01B13/02
Filed: 1979-12-04
Abstract: Cores of electrical cables which are insulated by a plastic, e.g. polyethylene, are stranded by directing the individual cores at a certain convergent angle to a stranding nipple. This angle is reduced immediately before the core entry in the stranding nipple from the initial angle to one of 10-40 deg. (15-25 deg.). The rollers which deflect the cores have a lining of PTFE. This results in a gentle stranding action which requires no new plant and can process larger cross-sections and/or insulating materials which are more sensitive to mechanical damage.

Title: Through contacts for printed circuit boards - by focussing high energy radiation beam on carbon based board to produce conductive carbon shell
Inventor: SZEPAN REINER DIPL PHYS
IPC: H05K3/00
Filed: 1980-01-15
Abstract: Drilled holes in printed circuit boards act as through contacts for the metallic conductor tracks. The through contacts are produced in one operation by directing a focussed beam of high- energy radiation on the board, which is a material on a carbon basis, to the exclusion of chemical oxidators. This produces a conductive sleeve of carbon particles along the inside surface of the hole which is either used itself as the through contact or forms the base for an electroplated coating of metal. This is a simple method of producing through contacts in non- conductive printed circuit boards.
