Patent number: 8371241Abstract: An electric circuit is applied to an object having a curved surface. The curved surface of the object is divided into sections, and the circuit is applied one section at a time. The circuit is formed between layers of dielectric material. The dielectric is applied by a computer-controlled device, which controls the position of a spray head and the rotation of the object, such that the spray head is held substantially perpendicular to the surface of the object at all times, and such that a controlled thickness of dielectric material can be deposited. The fine-featured circuits formed by the invention are rugged, and can be used on objects intended to be exposed to harsh environments.Type: GrantFiled: April 29, 2010Date of Patent: February 12, 2013Assignee: Max Levy Autograph, Inc.Inventors: Donald C. Sedberry, Derek S. Rollins, David S. Metzger

Patent number: 6553662Abstract: A high-density circuit has a plurality of conductors formed in grooves in a ceramic substrate, the conductors having a height less than that of the walls of the grooves. The substrate is embossed with a pattern of grooves corresponding to the grooves in an electroform made from a master tool. The same master tool is used to form a stencil which mates with the grooved substrate. A cermet paste is pushed through the stencil, so as to fill the bottom region of the grooves, and the stencil is then removed, leaving only the paste at the bottom of the grooves. The substrate is then fired, causing the substrate to harden, and causing the cermet to become conductive and to become firmly bonded to the substrate. Because the stencil and the substrate are made from the same, or replications of the same, master tool, the cermet paste can be laid down with great precision, thus enhancing the quality of the product, and reducing the cost of its manufacture.Type: GrantFiled: July 3, 2001Date of Patent: April 29, 2003Assignee: Max Levy Autograph, Inc.Inventor: Donald C.

Patent number: 5624708Abstract: The present invention is a high-density circuit, wherein the circuit conductors, and the spaces between conductors, are preferably less than about 0.005 inches wide, and wherein the lines are disposed over a relatively large area. The circuit is defined by a pattern of grooves in a dielectric substrate, and a conductive material is deposited in the grooves, and heated so as to form a tight bond with the substrate. The resulting circuit is stable, rugged, and capable of withstanding a wide range of adverse environmental conditions. The invention includes the circuit itself, as well as processes used in its manufacture. The invention also includes a high-density print head, for a thermal or electrostatic printer, made from the circuit described. The rugged, high-density circuit of the present invention can generate a set of very closely-spaced conductors which are then used to produce a high-density image.Type: GrantFiled: October 31, 1994Date of Patent: April 29, 1997Assignee: Max Levy Autograph, Inc.Inventor: Donald C.

Patent number: 5488394Abstract: A print head is made from an electronic circuit having a pattern of electric conductors embedded in a dielectric substrate. The conductors are formed by depositing a cermet material in grooves in the substrate, and heating the substrate in a kiln so as to make the cermet electrically conductive, and to form a very tight bond between the conductors and the substrate. The resulting circuit is stable, rugged, and capable of withstanding a wide range of adverse environmental conditions. The print head can be used in a thermal or electrostatic printer, or other type of printer using a print head powered by electric circuitry. The rugged, high-density circuit of the present invention can generate a set of very closely-spaced conductors which are then used to produce a high-density image. The invention also includes a multi-layered version of the print head, and permits the production of black and white or color halftone images having very large numbers of grey scale levels, and exceptional resolution.Type: GrantFiled: August 8, 1994Date of Patent: January 30, 1996Assignee: Max Levy Autograph, Inc.Inventor: Donald C.

Patent number: 4296397Abstract: A fine ozone corrosion resistant fuse wire is supported between conductive terminals which are, in turn, supported on and spaced apart by rigid insulator spacing means so that the fuse wire is extended. Insulator shield means is placed over the fuse wire over a substantial length of the insulator spacing means to shield the insulator spacing means from vaporized filament material to ensure that in all possible fuse failure modes that the circuit is completely broken but including a portion is unshielded so that vaporized material will plate on to the insulator to permit quick detection of a failed fuse. The rigid insulator spacing means may take the form of a rod generally parallel to the fuse with the terminals as end caps fitting over the rod or it may take the form of a tubular member fitting around portions of the terminals and confining the fuse internally, preferably so that oxygen cannot readily reach the fuse when it is used in a concentrated oxygen atmosphere.Type: GrantFiled: May 30, 1980Date of Patent: October 20, 1981Assignee: Welsbach Ozone Systems CorporationInventor: Donald C.
