Title: Control of drying time in a container - where 2 probes determine contents level and allow calculation of an operational dwell time which is compared with a preset dwell period
Inventor: OWERFELDT GUENTHER
IPC: F26B25/00
Filed: 1989-08-12
Abstract: A control system for filling and emptying a drying chamber is described. In the upper area of the container are two probes a small distance apart.

Title: Increased output of pocket-like articles based on thermoplastic film - two independent parallel film lines are passed to a welding station where a separating, non-stick film keeps them apart during welding
Inventor: HINTERSEER HEINZ DIPL ING
IPC: B29C65/04
Filed: 1989-09-04
Abstract: Mfr of envelope or pocket shaped articles from thermoplastic film, the film strip is either drawn from a roll and folded along the length or two or more film strips forming a group are brought together before passing welding and punching stations to produce individual prodts. Prodn can be increased if a second folded film strip or film group runs parallel to the first to the welding station.  At the welding point the parallel film lines are kept apart by a heat resistant non-stick film. The two film lines can thus be pressed together and simultaneously welded before separation once more into two lines. Equipment has two parallel film lines comprising film supply rolls, haul off devices, a folding device and a welding press with heating plates and welding tools. A heat resistant non-stick film is stretched laterally between the two film lines. USE/ADVANTAGE: For prodn of envelopes or pockets, particularly for documents or photographs. Allows increased production without increasing production speed.
