Title: Bottle label removing installation - softens labels with water, followed by brushes, or alternatively by using hot air jets
Inventor: SCHUMANN GUNTHER DR
IPC: B08B9/08
Filed: 1977-03-07
Abstract: The system for removing labels from beer or soft drink bottles, uses a caustic bath through which the bottles are passed. The bottles are also subjected to additional treatment such as passing them through rotating brushes and softening the labels by passing the bottles through a hot water bath. After passing through the brushes, they can then pass through sprays or washing water. Before passing through the caustic bath, the bottles may be passed through hot air jets at a temperature between 60-70 deg.C so as to soften the adhesive used during labelling, the air jets also removing the labels. Finally, remaining particles can be burnt and removed by brushes.

Patent DE-2801960-A1 (DE)
Title: Electrochemical machining of long grooves - by DC pulses of specified mark space ratio
Inventor: GOSGER PETER ING GRAD
IPC: B23H9/00
Filed: 1978-01-18
Abstract: The electrochemical machining of long grooves in the surface of metal workpieces uses d.c. pulses with a pulse length of less than the time required for the passage of the electrolyte through the working gap. At the end of every working pulse, a pause which is sufficient for the gap flushing is interposed. This prevents the increased metal removal rate near the end of the passage channel because of the rapid temperature rise in long grooves, followed by a decreased rate because of electrolyte sludging. Long grooves of uniform shape can now be produced.

Title: ignition point time control for IC engine - eliminates engine knocking by using counters to displace ignition point
Inventor: PAGEL ERNST-OLAV DR ING
IPC: F02P5/152
Filed: 1978-11-09
Abstract: The ignition point time control has a first stage forming a count state that increases when engine-knocking signals occur simultaneously with the release pulses initiating ignition and that decreases to zero when these two signals do not occur simultaneously. A second stage uses clock pulses to count backwards the count state of the first stage until zero is reached. The ignition delay is determined by the time needed for the second stage to count backwards to zero. The pinking signal lasts for a time corresponding to a given angle of rotation of the crank shaft. The release-pulse generator is connected at its output to an up/down counter that counts up in the presence of a knocking signal and down to zero in its absence.
