Patent DE-2030211-A1 (DE)
Title: Oil tank line system - with choke and sump to ensure uniform feed /drain speeds
IPC: F17D1/14
Filed: 1970-06-19
Abstract: Uniform filling and emptying rates to and from parallel tanks are achieved by a choke built into the horizontal pipeline linking the tanks via connection pieces. The choke reduces the flow in the line sector fitted with the individual tank feeds far enough to ensure that the speeds are uniform. A diverter can be used as choke or again the line can terminate as an immersion tube dipped into a sump at relatively lower level. If the tube is used, it links to the rising connection of the line and fills out the line except for a narrow annular gap. The flow rates are balanced out and thus accurate readings obtained of individual tank levels.

Title: Sugar beet helical screw press - has variable dia core with convex shape to improve drying and extraction
Inventor: MAINKA HELMUT
IPC: B30B9/12
Filed: 1973-12-22
Abstract: The press used for extracting juice from sliced sugar has a helical screw whose roof diameter varies. The screw is designed so that the inlet area of the press is greater than the outlet area. The press spindle helix is arranged on a cylindrical central spindle at the inlet. This cylindrical section is gradually joined, by a concave section to a convex section with increasing diameter. The sliced sugar beet is fed into the cylinder and the inlet section helical blades precompress this material by helical fins. The juice is extracted through perforated cylindrical walls of the press. The gap between the screw and walls narrows and hence juice is efficiently extracted and relatively dry pulp is produced.
