Matthew Lowney has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Direct metal deposition apparatus utilizing rapid-response diode laser source
    Patent number: 7765022
    Abstract: The present invention incorporates one or more diode lasers for the high-power CO2 or Nd-YAG lasers currently used in closed-loop DMD systems. Being semiconductor-based, such devices are almost instantaneously responsive to the electrical input. As such, a DMD system driven by a diode laser according to the invention provides a much faster response compared to other sources. The faster response time, in turn, provides for enhanced dimensional control and capability to produce intricate components with better dimensional accuracy.

  • COMPOUND MOLD TOOLING FOR CONTROLLED HEAT TRANSFER
    Publication number: 20080003323
    Abstract: In one embodiment, a tool for forming an article in a molding operation has a tool body formed from a non-particulate material, with a particulate material bonded to the body. The body provides a forming surface for forming the article. The particulate material, or the particulate material and the tool body collectively provide a duct for conveying a fluid for transfer of heat with the forming surface. In another embodiment, the tool has a tool body formed from a non-particulate material with a cavity and the particulate material is disposed within the cavity. A heat transfer material is disposed in the cavity bonding the particulate material to the tool body. Methods for manufacturing such tools are also disclosed.
