Patent DE-3844566-A1 (DE)
Title: Process and apparatus for separating solvents and oils
Inventor: VOM DAHL UWE
IPC: B01D3/34
Filed: 1988-06-21
Abstract: Oil-solvent solutions are separated by azeotropic distillation. Despite the reduction of the solvent content in the oil achieved thereby, the latter is considered as special waste. The novel process is to lead to virtually solvent-free oil. The oil-solvent solution is vortexed with dry gas. The gas enriched with solvent is conducted away and dried by intensive cooling. The thawed solvent is removed, the dried gas is conducted off and the solvent-free oil is discharged. Separating solvents and oils from an oil-solvent solution, in particular chlorinated or fluorinated hydrocarbons from machining oils.

Title: Door station of a domestic telephone system equipped with voice control
Inventor: MANSEL WERNER
IPC: H04M11/02
Filed: 1989-04-04
Abstract: In a door station equipped with voice control which has a microphone and a loudspeaker and which can be connected to a number of domestic telephones, the microphone of the domestic telephone is intended to have virtually unconditional priority; however, acoustic feedback within the door station is intended to be prevented in every case. For this purpose, it is proposed that the microphone and the loudspeaker of the door station are connected via a transformer of a hybrid circuit to the line leading to the domestic telephones, and that the loudspeaker-side output of the hybrid circuit is monitored by a comparator which, when speech voltages occur via amplifiers, deactivates switches disposed downstream of the microphone and activates switches disposed upstream of the loudspeaker.

Patent DE-3920234-A1 (DE)
Inventor: RAUSER HORST DIPL ING
IPC: H04N5/76
Filed: 1989-06-21
Abstract: The invention concerns a video recorder (VR) with a text-signal generation facility.

Title: Tubular paper box-prodn. machine - winds walls round shaping cores on capstan after parting-off
Inventor: ITO SADAHARU
IPC: B31B105/00
Filed: 1989-07-24
Abstract: The machine produces paper boxes each with a bottom and a tubular sidewall.

First and second gluing units (13, 14) apply adhesive along one lengthwise edge and the cut lines respectively, after which a cutter unit (15) parts the strip off along successive cut lines so as to form the sidewalls. The latter are then sucked against the wound round shaping cores (161) protruding radially from a rotary capstan (16) and are pressed and heated so as to harden the adhesive and secure the overlapping portions together. A second feed mechanism delivers the bottoms to the core ends, the wall ends being rolled over and glued to them via the strips formed along the lengthwise edges. USE/ADVANTAGE - No handling operations are needed between wall formation and assembly, during mfr. of paper boxes.
