Patent number: 4925607Abstract: A material hermetically seals two members. One member may be titanium or a titanium alloy and the other member may be a noble metal such as platinum. The seal is resistant to acids and alkalis and is substantially impervious to shocks resulting from mechanical forces or abrupt changes in temperature. The material includes a pair of fluxes having different melting temperatures and oxides of zinc and zirconium. The oxides of zinc and zirconium become crystallized at the surface between one of the members and the material. An oxygen valence bond is also produced between the material and such member. The material becomes progressively amorphous with progressive distances from such member. The material is formed by progressive heatings for at least a pair of periods of time insufficient to crystallize all of the material and by rapid coolings of the material after each of such heatings.Type: GrantFiled: October 20, 1983Date of Patent: May 15, 1990Assignee: James C.

Patent number: 4657337Abstract: A terminal pin extends through a first housing portion and has a flange. A hard bead having a high melting temperature is disposed on the flange. At least one layer of insulating material is disposed on the bead and is provided with a lower melting temperature than the bead. A second housing portion is attached to the first housing portion as by welding to define a housing. The layer of insulating material is melted and the terminal pin is pressed in a direction, while the layer is molten, to eliminate any air pockets in the layer and to provide for a hermetic sealing of the layer of insulating material to the bead, the terminal pin and the housing. Instead of a single layer of insulating material, at least a pair of insulating materials may be used. These layers may have melting temperatures less than the bead and the layer closest to the bead may have a higher melting temperature than the layer removed from the bead. The assembly of the connector may be accomplished by the rotation of a turntable.Type: GrantFiled: June 29, 1984Date of Patent: April 14, 1987Inventor: James C. Kyle

Patent number: 4654752Abstract: A first insulating member has electrical terminals and may constitute a semi-conductor chip. A second insulating member made from a first insulating material may constitute a heat sink for the semi-conductor chip. Electrical leads may extend through the second insulating member to the periphery of the member. A mound formed from a mixture of electrically conductive particles and electrically insulating particles is disposed between the first and second members. The electrically conductive particles may have sizes to a few hundred microns. When the first and second members are pressed toward each other, the electrically conductive particles migrate toward one another to establish an electrical path to the electrical terminals on the first member and establish electrical continuity between the electrical leads and the electrical terminals. At the same time, the electrically insulating particles tend to at least partially envelope the electrically conductive particles.Type: GrantFiled: December 4, 1984Date of Patent: March 31, 1987Inventor: James C.

Patent number: 4593758Abstract: First and second spaced members are hermetically sealed by a partially amorphous and partially crystalline insulating material. The insulating material is non-hygroscopic and is able to withstand forces of about 26,000 psi at about 700.degree. F. It may provide resistances of at least 10,000 megohms even when subjected to 500 volts AC or DC and to steam at about 212.degree. F. for three (3) days. A second insulating layer may be fused to the first insulating layer with essentially the same properties and composition as the first layer. However, the second layer may be more crystalline than the first layer to provide a mechanical and chemical barrier. The insulating materials may be formed from the oxides of lead, zinc, aluminum, silicon, cerium, lanthanum, cobalt, sodium, zirconium, bismuth and molybdenum. The oxides of lead, silicon, bismuth and sodium may be glass formers. The oxides of cerium, lanthanum and zirconium may form crystals. A mixture of the oxides may be heated to at least 2000.degree.

Patent number: 4518820Abstract: A ferrule made from an electrically conductive material has a coefficient of thermal expansion which changes at a particular rate with temperature changes. The ferrule is attached to an electrically conductive lid as by the application of heat and has a body portion pivotally movable at a particular position, such as a heat sink, on the body portion. Such heat sink has a minimal thickness in the body portion. When the ferrule is being attached to the lid as by heat, the heat becomes concentrated in the ferrule at the heat sink. A first ceramic material disposed within the ferrule has hard and rigid properties and is supported by the ferrule above the heat sink. The first ceramic material is preferably fused partially to the ferrule to provide for variations in its pivotal disposition relative to the ferrule. A second ceramic material within the ferrule is fused to the ferrule and the first ceramic material. The second ceramic material has more amorphous properties than the first ceramic material.Type: GrantFiled: November 4, 1982Date of Patent: May 21, 1985Inventor: James C. Kyle

Patent number: 4493378Abstract: First and second members are disposed in spaced relationship to each other. The members may be electrically conductive. The first member may be provided with a particular coefficient of thermal expansion which is higher than the coefficient of the second member. A plurality of layers of insulating material are disposed between the first and second members and are hermetically sealed to one another and to the first and second members. Each of the layers of insulating material has a coefficient of thermal expansion less than the particular coefficient. The progressive layers of insulating material from the first member have coefficients of thermal expansion of decreased value. This causes the layers of insulating material to have coefficients of thermal expansion which approach the coefficient of the second member with progressive distances toward the second member.Type: GrantFiled: July 16, 1981Date of Patent: January 15, 1985Inventor: James C.

Patent number: 4493218Abstract: Apparatus indicating the linear movement of a member includes a pulley and a spring disposed on the pulley and having characteristics of producing a force substantially linearly related to its speed of movement with respect to the pulley. A motor produces a displacement of the spring relative to the pulley. A transducer produces a signal related to the speed of movement of the spring relative to the pulley at each instant and provides a signal linearly related at that instant to the distance of the spring movement at that instant. A cam may also be included for converting the movement of the spring into a non-linear function having particular characteristics. Such cam may have a particular non-linear relationship on its external periphery relative to its axis of rotation. The cam and the pulley may be coupled to opposite ends of the spring to provide a conversion between the linear movement of the spring and the particular non-linear relationship provided by the cam.Type: GrantFiled: January 27, 1983Date of Patent: January 15, 1985Inventor: James C.
