Introduction

Paul G. Friedmann is a notable inventor based in Madison, NJ (US), recognized for his contributions to cooling technologies and molten metal measurement systems. With a total of 2 patents, Friedmann has made significant advancements in the field of industrial processes.

Latest Patents

Friedmann's latest patents include a "Method and apparatus for cooling a moving chill substrate." This innovative cooling apparatus features a series of spray nozzles designed to spray coolant against one surface of a moving chill substrate. The apparatus is equipped with an enclosure that applies vacuum to prevent the migration of the sprayed coolant. This design ensures that any coolant escaping along the sealed edges is forced back into the enclosure by a pressure gradient. The edges are sealed using elongated plastic rods, and scrapers are included to remove any residual coolant from the sprayed surface. The coolant is sprayed at high velocity to enhance its heat transfer efficiency.

Another significant patent is the "Method and apparatus for measuring crucible level of molten metal." This invention simplifies the measurement of molten metal levels in a crucible heated by an induction coil. By utilizing a variable frequency power supply, the power provided to the coil remains substantially constant, regardless of variations in power factor. The detection of frequency changes in the power supplied to the induction coil indicates changes in the power factor due to variations in the molten metal level.
