  • Patent number: 5313048
    Abstract: A high temperature bottom-loading research furnace is provided having a lifting mechanism comprising a V-shaped wheels and corresponding guide members for raising and lowering the furnace oven door. The lifting mechanism facilitates precise opening and closing of the door which, along with other mechanical features, reduces the heat loss from the furnace and, accordingly, reduces the amount of energy needed to operate the furnace.
    Type: Grant
    Filed: July 7, 1992
    Date of Patent: May 17, 1994
    Assignee: Morris Berg
    Inventors: Morris Berg, Patrick T. McGuire
  • Patent number: 4451429
    Abstract: A method of reclaiming precious metal incidentally sputtered into vacuum chamber walls, fixtures, and the like. The incidentally sputtered precious metal is reclaimed by grinding it into a metal powder that is useful as an electrical conductor in a cermet ink. Power can also be made by pulverizing the principally sputtered metal too.

    Inventors: Morris Berg, Carl F. Schaefer, William J. Johnston
  • Patent number: 4312770
    Abstract: This invention relates to resistor compositions comprising, in % by weight, about 5-24% RuO.sub.2, about 10-20% Ag, about 3-8% Sb.sub.2 O.sub.3, about 8-12% CdO, about 35 to 70% lead-borosilicate glass, up to about 4% Ta.sub.2 O.sub.5 and up to about 2% thermistor powder such as at least one of the transition metals Mn.sub.2 O.sub.3, NiO, CuO, Cr.sub.2 O.sub.3 and ZnO. These resistor compositions are adapted to be dispersed in a liquid vehicle to form a resistor ink or paste that can be applied to a surface of a ceramic substrate and fired to form a resistor having stable electrical and mechanical properties.

    Inventors: Ruey J. Yu, Morris Berg
  • Patent number: 4253934
    Abstract: In a preferred embodiment of the invention, a method of making a solid electrolyte electrochemical-type exhaust gas oxygen sensor. A platinum exhaust electrode is sputtered onto a zirconia body and the body then heated in nitrogen at C. for at least 30 minutes to reduce rich-to-lean switching time response.

  • Patent number: 4051072
    Abstract: A method for making improved pellet type catalysts utilizing a support material having relatively high alkali metal content, comprising the steps of grinding the support material to the desired size, forming the pellet into the desired shape and size, calcining the pellet to obtain the desired surface area, soaking the calcined pellet in a dilute acid for a short period of time to form the alkali metal salt of the acid to a controlled depth inward from the surface of the pellet, and impregnating the pellet with the desired catalytically active metallic material after draining the acid wash solution, the depth of penetration of the catalytic material being limited to the depth treated by the acid wash.

    Inventors: Raymond E. Bedford, Morris Berg
  • Patent number: 3954672
    Abstract: Cordierite refractory compositions made from a mixture of talc, clay, calcined kyanite, alumina and water, the composition being such as to result on firing in a body having cordierite as the major crystalline phase and mullite as the minor crystalline phase and wherein the amount of Na.sub.2 O and K.sub.2 O is not in excess of about 0.14% by weight of the batch dry materials, such compositions being suitable for making a catalyst substrate or support in the form of an extruded multi-tubular refractory body as well as other ceramic bodies such as turbine engine components, heat exchanger cores and furnace ware which have a requirement for high resistance to heat shock and low thermal expansion characteristics.
