Title: Innovations of Stephen A. Thompson
Introduction
Stephen A. Thompson is a notable inventor based in St. Bruno, California. He has made significant contributions to the field of metal casting and injection systems. With a total of four patents to his name, Thompson's work has advanced the technology used in manufacturing processes.
Latest Patents
One of Thompson's latest patents is a double acting cylinder for filling dies with molten metal. This innovative melting casting process produces meltable metal cores for subsequent molding of components made of plastic material and encapsulated components such as turbine blades. The process utilizes a double acting piston in a cylinder, allowing for unlimited dispensing capacity without pauses between piston strokes. The apparatus includes a tank for containing molten metal, a double acting cylinder with an injection piston, and an operating mechanism for reciprocating the piston. Valve mechanisms ensure that as the piston moves, molten metal flows into a die while the cylinder remains full of molten metal.
Another significant patent is a method of and system for controlling the flow of molten liquid to cast metal. This improved control system is designed for casting metal alloys with low melting temperatures. It features a fluid-operated drive cylinder with a drive piston connected to the injection piston. A transducer linked to the injection piston provides location indications, while a controller compares the position of the injection piston with a predetermined time/distance profile. This system produces an injection stroke signal to control the drive cylinder, ensuring the injection piston follows the desired profile and avoids porosity in castings.
