Latest Patents

One of Ross's latest patents is the "Torch support and height sensor apparatus for shape cutting machines." This invention provides an improved method for employing a plasma-arc cutting torch to cut a metal plate. The improvement consists of operating the torch with its lower portion submerged in a layer of water provided over the workpiece. To allow automatic adjustment of the torch to the appropriate working height above the workpiece, a mechanism is provided for mounting the torch with respect to the support carriage, which guides its horizontal path. This mounting mechanism allows relative up and down movement between the torch and the support carriage and includes a detecting mechanism. This mechanism consists of a frame and vertical slides on which the cutting torch is secured. When the mounting mechanism is lowered to the point where the torch touches the metal plate, the detecting mechanism communicates a signal for the upward movement of the mounting mechanism, thereby raising the torch to a predetermined cutting distance from the metal plate.

Another significant patent is the "Ground freezing method." This invention describes an apparatus and method of freezing a large volume of ground for tunnel construction and similar applications utilizing liquefied nitrogen. The apparatus consists of a series of freeze pipes embedded in the ground, each consisting of a conductor tube and an inner header tube. The header tube of each succeeding freeze pipe in the series has discharge holes of a predetermined cross-section, allowing for greater control of gaseous and liquefied nitrogen pressure throughout the system. This method and apparatus enable more accurate control of ground freezing by merely controlling the inlet liquefied nitrogen pressure and the exhaust gaseous nitrogen temperature.
