Patent CH-650527-A5 (CH)
Inventor: AESCHBACH HERMANN ALBERT
IPC: C12J1/10
Filed: 1979-09-26
Abstract: A method for the submersed, automatically controlled production of fermentation vinegar from ethanol is conducted in two stages. The installation for accomplishing the method includes one or more pre-fermenters and a product fermenter, in connection with which each pre-fermenter exhibits a volume 1.7 to 3.5 times that of the product fermenter. The terminus of the fermentation is reached in the product fermenter when the dissolved oxygen, indicated by means of an oxygen electrode, rises, at which point the product valve is opened. The product fermenter is evacuated when no more alcohol remainder is present. In the final step the alcohol is therefore completely utilized.

Abstract: A process for cutting at least one surface of a workpiece wherein a face milling cutter is used in working the surface in both pulling and pushing cuts and wherein the camber angle as measured with respect to the normal to said surface is maintained at a constant value during both pulling and pushing cuts. A face milling cutter adapted for use in both pushing and pulling cuts and used in the process has an angle of rotation with a selected chamber angle. The cutting face has inside and outside cutting edges which define a polygonal cutting edge geometry and intersect at a selected angle of intersection. The angle of intersection has a line of bisection which as measured with respect to the axis defines an inclination angle generally corresponding to the chamber angle.
