Title: Automatic dough dividing/kneading machine - with oil wiping station to prevent dough/piston crown sticking
Inventor: SCHROEDER HERBERT
IPC: A21C7/00
Filed: 1975-02-27
Abstract: In the parent patent, a revolving drum contains four rows of measuring chambers with pistons, 90 degrees offset relative to each other, each row with five chambers.

Title: Quick replacement filter for aggressive or radioactive substances - has filter insert in tube between two clamping plates
Inventor: PFEIFER KURT ING GRAD
IPC: B01D29/01
Filed: 1976-04-26
Abstract: Filter comprising a replaceable filter insert is for filtering solids from gases or liws. The filter insert is mounted between two clamping plates which are movable towards and away from the one another transversely to the plane, one plate having the inlet fixed to it, while the outlet is fixed to the other plate. The filter insert is housed in an open-ended tube or similar housing between the two plates and compression springs bias the plates apart; a pressing mechanism enables the two plates to be pressed towards each other, so that the open-ended tube contg. the filter insert is clamped between the two plates. Used for any application where the filter insert must be changed rapidly at regular intervals, and in particular where aggressive gases, acids or liws, or radioactive substances are filtered. The filter insert can be rapidly removed as soon as the pressing mechanism has been released to allow the two plates to move apart. It is not necessary to disconnect the plates from the inlet and outlet pipes for this purpose.
