Title: Thomas P. Ladisch: Inventor of Liquid-Processing and Valve Technologies

Introduction

Thomas P. Ladisch is an inventor associated with Alburtis, Pennsylvania, whose patents address equipment for liquid processing and tank-valve design. His work includes technologies intended to support controlled separation and sterilizable fluid handling.

Latest Patents

Ladisch’s patent for an apparatus for mixing liquids used in countercurrent multiphase liquid separation describes a reusable, multistage system. It is designed to support precise liquid transfer, air exclusion, homogeneous mixing, and isolation from the surrounding atmosphere, without valves. A sliding bottom moves within a chamber, while an internal mixing element—preferably a magnetic stainless-steel ball—can be reciprocated from outside the apparatus. Stops limit the bottom’s movement, and the patent describes several ways to actuate the device.

His patent for a flush-sealing tank valve with a diaphragm describes a valve designed to sit flush with the bottom of a tank and serve as a sterilizable drain. A piston-mounted diaphragm seals an opening, and the design includes a steam inlet and outlet. It also provides a containment outlet to help manage tank contents if the diaphragm ruptures. The diaphragm may be made from PEEK, and a threaded handle moves the operator piston to open or close the valve.

Together, these 2 patents reflect Ladisch’s focus on practical equipment for controlled liquid processing and tank drainage.

Career Highlights

The supplied career information associates Ladisch with E. I. du Pont de Nemours and Company. His patented work spans both multiphase separation equipment and a diaphragm-based tank valve.
