  • Publication number: 20190358702
    Abstract: Liquid, cold-casting, multi-structure metal alloy to produce precision molds. After cold hardening and special treatments high scratch and impact resistance with steel similar mechanical properties created—the process causes zero health or environmental problems. Non digital system reproducing any shape and surface structure replacing all presently known machining methods. A unique system with great social economic impact on merging and other markets.

  • Patent number: 5743179
    Abstract: The present invention relates generally to a frameless high pressure press. The high pressure press includes first and second opposed plates that are at least partially surrounded by a wrapping structure. A lift device is positioned on one of the first and second plates at a location offset from the wrapping structure. The press also includes a linkage structure that transfers force generated by the lift device to the wrapping structure such that the wrapping structure forces the plates together. The linkage structure includes a tensioning member connected to the wrapping structure and generally transversely aligned with respect to the plates. The linkage structure also includes a cross member that extends between the lift device and the tensioning mechanism. The length of the tensioning member can be adjusted to control the level of force multiplication generated by the press.

  • Patent number: 5298102
    Abstract: An apparatus and method for forming and bonding skins to shaped articles includes a first sleeve having an open top end and a lower end closed by a bottom plate, a second sleeve having an open top end and a lower second end which is slidable arranged, and coaxially connected, with the top end of the first sleeve, a top plate, and a forming medium. The forming medium may be an elastic medium, a fluid, or a plurality of low-friction particles, and may be covered by a flexible open pore sponge blanket. The shaped article and the laminate skin to be bonded thereto are placed on the forming medium within a space defined in part by the second sleeve, and the forming medium is pressurized so as to cause the skin to form and bond to the shaped article.
