Title: The Innovative Contributions of Robert J Dorsey
Introduction
Robert J Dorsey is a notable inventor based in Chicago, IL (US), recognized for his contributions to hydraulic press technology. He holds a total of 5 patents, showcasing his innovative spirit and technical expertise in the field.
Latest Patents
One of his latest patents is a hydraulic refractory press that includes product thickness or density control. This hydraulic press features a frame with spaced-apart vertical side members and a crown, along with a mold box that is rigidly supported between the vertical side members. The design includes a lower plunger assembly positioned below the mold box, which contains at least one plunger that extends upwardly into the mold cavity. An ejection cylinder assembly is integrated to facilitate the selective vertical movement of the lower plunger assembly. Additionally, an upper plunger assembly is situated above the mold box, featuring an upper plunger that extends downwardly into the mold cavity. A hydraulic ram supports the upper plunger assembly, allowing for vertical movement in relation to the mold box and the lower plunger assembly. The hydraulic ram consists of a cylinder fixed to the lower plunger assembly, with a ram housed within the cylinder to drive the upper plunger assembly downwardly. To ensure precise control over the size of the compressed refractory product, rack and pinion position encoders are included to sense the relative movement of both plunger assemblies. Furthermore, pressure transducers are utilized to manage the compression pressure and the density of the resulting products. Another significant patent involves a mold assembly designed for compressing refractory material, which allows for quick removal of the mold box from the supporting mold table.
