Abstract: Relates to tooling devices for removing piston pins for automobile engine pistons for repair or replacement and for installing a repaired or new pin in the piston. More specifically, the invention accomplishes these objects without imposing any load on the piston, thus eliminating the possibility of distorting or otherwise damaging the softer piston. Instead, one of the supporting structures of the tool is shaped in a special way to enter the skirt of the piston and underlay the smaller end of the connecting rod in opposing relation to the driving forces tending to advance the piston pin through the bore of the connecting rod either to remove the pin or to install the repaired pin or its replacement.

Abstract: A display device includes a layer of electroluminescent material which is capable of conducting electric current. The electroluminescent material is sandwiched between a pair of electrodes to which a voltage is to be applied to excite the electroluminescent material to luminescence. The display device is manufactured by disposing on an assembly comprising a substrate with one of the said electrodes thereon, two masks in which are formed aligned apertures defining a region in which the electroluminescent material is to be provided. The electroluminescent material is disposed in the apertures, and, after that material has solidified one of the masks is removed, the other of the electrodes then being formed on the exposed surface of the electroluminescent material and within slots in the remaining mask and the mask is removed.

Abstract: A microwave magnetron having an anode assembly formed of a plurality of vanes contacting an anode cylinder and extending inwardly toward a central region containing an electron source in which the anode vanes have notches adjacent the anode cylinder into which retaining rings have been deformed to maintain the vanes in a spaced peripheral location in firm metallic contact with the anode cylinder and with the assembly brazed together by heating the assembly with a plurality of straps contacting alternate vanes adjacent their inner ends to form a unitary electrically conductive anode resonator.

Abstract: A center column press is provided for use in automobile related applications. The press includes a center column mounted on a base with a vertically extending center wall interconnecting two opposed, vertically extending side walls to define at least one vertically extending channel on each side of the center wall. Press means are mounted within one of the channels and include a moveable ram adapted to travel in a vertical direction to effect a pressing operation. An adjustable work table is adjustably mounted in said one channel between the press means and the base and may include an adjustable, self-storing leveling bar. A nesting block is pivotably mounted within said one channel between said press means and said work table. Storage means are provided within said other channel for press tooling.

Abstract: A stone setting press for securely fastening stones to settings comprising an arbor supported on a frame or base, shaped to receive and support a ring setting. A forming die at the end of a shaft is shaped to deform the prongs of a setting about a stone. The shaft is supported on the frame for axial movement to and from a position in which the die shapes the prongs. A leverage system having variable mechanical advantage is used to actuate the shaft.

Abstract: An improved wedge-based lamp and method of manufacture are disclosed in which conductive leads and an exhaust tube are positioned and held in the pinch end of a flared section of glass tubing. After one or more filaments are attached to the leads and accurately positioned relative to the pinch end, an envelope is fastened to the flare to enclose the filaments and the lamp is exhausted or filled with inert gas(es) via the exhaust tube.

Abstract: Method of manufacturing grid electrodes wherein a grid sleeve is produced by depositing pyrolytic graphite on a polished mandril of glassy carbon and provided with apertures by means of the laser beam, then the finished grid is provided, by means of hot gas pyrolysis, with a second layer of highly oriented pyrolytic graphite, and thermally and/or mechanically after-treated at 3000.degree. to 3800.degree. K and 10-500 bar.

Abstract: A press machine comprising a frame having a pair of spaced legs, and adjustable press bed transversely carried on the legs so as to be adjustable in position along the length thereof wherein abutment supporting blocks carried on the frame legs support abutment members for supporting the press bed. A bridge plate is secured to the legs and extends over the abutment supporting blocks for aiding in retaining the abutment member while increasing the structural integrity of the frame legs so as to increase the load capacity thereof.

Abstract: A forcing press for simultaneously pressing members onto opposite ends of a central member, such as railroad wheels onto an axle, wherein the press is prestressed by exerting balancing force against opposite ends of the axle prior to pressing the wheels onto the ends of the axle and including mechanism for simultaneously pressing the wheels onto the axle.

Abstract: A charging electrode array for droplets formed from a plurality of liquid streams is formed in a silicon substrate. The substrate also has an FET shift register and FET latch circuits formed therein to supply signals to the charging electrodes, which are formed by diffusing a dopant into at least a selected portion of the wall of each of a plurality of passages in the substrate.

Abstract: Bearing material, such as an aluminum alloy, is applied and bonded to the support surface by heating the surface to 500 to 700 degrees Fahrenheit, applying the bearing material in sheet form to the surface at one edge thereof, and spreading the material across the surface by moving a zone of pressure application to the bearing material from one edge of the surface to an opposed edge so as to reduce the thickness of the bearing material and to provide a flow which continually brings fresh previously unexposed bearing material from the interior of the sheet so as to effect a molecular bond. Typical applications are to sleeve type bearings or bushings, and a preferred use of the invention is the application of bearing material to connecting rods.
