Title: Low cost valve for gaseous medium - uses elastic valve ball as regulating element
Inventor: BERKHOF HENDRIKUS
IPC: F16K11/056
Filed: 1974-02-04
Abstract: A valve body for gaseous medium has a cylindrical hole to form an inlet and outlet port. A transverse hole joins the main bore at mid length. The outside end of the transverse hole is tapped so that it can accommodate a regulating screw. At the intersection of the two holes, a flexible plastic or rubber ball is placed. When the ball is not deformed by the regulating screw, the valve is at maximum flow. By screwing the regulating screw into the valve, the ball is being deformed and thus gradually reduces the medium flow to zero. The elastic valve ball acts as self locking element on the regulating screw. By using two or three balls, a finer flow regulation is possible.

Title: Distillery control unit attached to a final condenser - automatically separates the distillate fractions according to instrument settings
IPC: B01D5/00
Filed: 1974-07-05
Abstract: An attachment for the final condenser of a still, has an inlet to be connected to the condenser outlet, followed by 2 changeover valves controlled automatically by monitors, responding to the parameters of the distillate, such, as, volume, weight, time, or specific gravity, for separately regulating the flow of the first, main and end fractions. The nominal value of the parameters can be preselected by adjustable devices, and the flow of the distillate is distributed from a column with an annular overflow trough, from which 2 branch lines drain from different levels. One of the lines feeds the changeover valves and outlet pipes. The other branch feeds the first fraction vessel in which a float lifted by the distillate closes a circuit energising one of the changeover valves. The overflow and first fraction vessels may have solenoid controlled shut off valves similar to the changeover valves or have manually operated valves. In the overflow vessel a hydrometer is provided which, as the density rises, energises the other changeover valve. The operative is relieved of all tasks except to see that the various fractions are collected in the appropriate vessels.
