Patent number: 10335889Abstract: The present disclosure provides a system for printing at least a portion of a three-dimensional (3D) object. The system may comprise a source of at least one feedstock, a support for supporting at least a portion of the 3D object, a feeder for directing at least one feedstock from the source towards the support, and a power supply for supplying electrical current. The system may comprise a controller operatively coupled to the power supply. The controller may receive a computational representation of the 3D object. The controller may direct the at least one feedstock through a feeder towards the support and may direct electrical current through the at least one feedstock and into the support. The controller may subject such feedstock to Joule heating such that at least a portion of such feedstock may deposit adjacent to the support, thereby printing the 3D object in accordance with the computational representation.Type: GrantFiled: March 30, 2018Date of Patent: July 2, 2019Assignee: DIGITAL ALLOYS INCORPORATEDInventors: Paul Burke, Mateo Pena Doll

Patent number: 4173457Abstract: A mining or drilling tool which has a region subject to excessive wear is hardfaced on such region with sintered chromium carbide particles metallurgically bonded on the tool by a steel matrix which is alloyed with the particles at the interfaces therebetween. The particles are in a size range of 10 to 60 mesh and are present in an amount for effective abrasion resistance. The particles are comprised of grains of chromium carbide having an average size in the range of 0.5 to 25 microns disposed in a binder comprising a major portion of nickel. Minor portions of grain growth inhibitors, particularly, tinanium carbide and molybdenum carbide, are preferably components of the carbide particles so as to inhibit growth of the chromium carbide grains to be such that such grains have an average size in the range of 0.5 to 15 microns.Type: GrantFiled: March 23, 1978Date of Patent: November 6, 1979Assignee: Alloys, IncorporatedInventor: Thomas J.

Patent number: 3946190Abstract: A conductive hermetic sealing cover for a container is fabricated by disposing the cover with a superimposed preformed heat-fusible conductive ring having outer dimensions similar to those of the cover in a shallow cavity of a nonconductive supporting member, the cavity having dimensions only slightly larger than those of the cover to secure registration between the ring and the periphery of the cover. A plurality of pairs of spaced electrodes are resiliently engaged with the ring with substantially equal contact pressures and a separate pulse of current is passed between the electrodes of each pair and through the ring and the cover, thereby producing an effective spot weld between the ring and the cover adjacent each of the electrodes. The term "ring" is used herein and in the appended claims in its generic sense to include a closed loop of conductive material of any configuration corresponding to the periphery of the cover, usually round or rectangular.Type: GrantFiled: October 22, 1974Date of Patent: March 23, 1976Assignee: Semi-Alloys IncorporatedInventor: Norman Hascoe
