Patent DE-2014697-A1 (DE)
Title: Feeding rods to a concrete reinforcementmesh welder
IPC: B23K11/00
Filed: 1970-03-26
Abstract: Wire rods are fed mechanically to the welding machine under the control of one man. A gripper picks up the ends of the rods and carries the towards the welder where the ends are entered into pairs of rolls fixed in a framework. This moves horizontally and vertically to bring the rods opposite the point of entry to the welder, in which position they are held from underneath in another carriage. This then feeds them into the welder step by step for welding to the transverse rods already there. When about half the welds have been made, another mechanism takes over, pulling the partly completed mesh through the mchine, and the feed device is thereby released to receive the next batch of rods for the next mesh. By the use of photo cells, etc., the process can be automated.

Title: Thin film vapour deposition on substrate - in HF magnetic field perpendicular to stationary field producing resonance ionization
Inventor: KAUSCHE HELMOLD DIPL-PHYS
IPC: C23C14/00
Filed: 1973-09-04
Abstract: Vapour deposition of thin oxide and nitride films on a substrate in a reaction chamber made of insulating material uses the electrodeless ring discharge of an inductively coupled HF coil to ionize the reactant gas. The magnetic stationary field from a pair of coils at right angles to the alternating field is superimposed to the latter in an electron-cyclotron resonance or electron-helicon resonance. This achieves fully completed reactions resulting in thin films of stable compounded stages. They have good mechanical and optical properties and are free from absorption.
