Abstract: A method for forming a back panel for a plasma display includes preparing a green ceramic tape having a temperature coefficient of expansion (TCE) which matches the TCE of a metal core. Barrier ribs are formed on the back panel by embossing or scribing the green ceramic tape. The formed green ceramic tape is then bonded to the metal core. Finally, the bonded formed green ceramic tape and the metal core are cofired to form the back panel.

Abstract: A plasma display having a transparent front panel spaced from a back panel which is a metal core having layers of a dielectric material extending over and bonded to the core. Conductive electrodes are on the surface of or imbedded in the dielectric layer of the back panel. The materials of which the back panel is made are chosen to form a back panel having a thermal coefficient of expansion compatible with that of the front panel. Barrier ribs are formed on the back panel by embossing the green tape before cofiring the bonded assembly. The green tape is embossed using pulsed pressure and an embossing tool that is formed by assembling embossing members and spacing members in compression. The embossing tool further includes elastic spacers mounted outside of the embossing tool and in a position such that the elastic spacers are held in compression during the embossing operation to aid in releasing the embossed green tape from the embossing tool after the embossing operation.

Conductive electrodes are on the surface of or imbedded in the dielectric layer of the back panel. The materials of which the back panel is made are chosen to form a back panel having a thermal coefficient of expansion compatible with that of the front panel. The dielectric material is made from a green ceramic tape which is bonded to the core and cofired with the core to form the back panel. Barrier ribs are formed on the back panel by embossing or scribing the green tape before cofiring the bonded assembly. Slight differences in the TCEs of the front and back panels may be compensated for by heating the panel having the lower TCE to a temperature hotter than the panel having the lower TCE during the frit seal process.

Abstract: An electrical terminal applicator is provided for crimping terminals onto electrical wires. An applicator ram is movable mounted on an applicator frame and is drivable by a press ram through a working stroke towards, and a return stroke away from, a crimping anvil. A crimping die is mounted on the applicator ram for cooperation with the anvil to crimp a portion of a terminal onto a wire during each working stroke of the applicator ram. A pneumatic piston-and-cylinder device is mounted directly on the applicator frame adjacent the applicator ram and is connected to the crimping die for moving the crimping die through a first portion of movement into engagement with an uncrimped terminal to preposition the terminal for crimping thereof.

Abstract: An electrical terminal applicator is provided for crimping terminals onto wires, the terminals being secured to a tape in a side-by-side relationship with their axes extending laterally of the tape. An applicator ram is drivable in a first path for moving a crimping die toward and away from a crimping anvil. A track guides the tape in a second path which generally intersects the first path of the ram. The track includes a platen and a guide plate which define a pair of opposing clamping jaws for engaging and gripping opposite surfaces of the tape and pulling the tape laterally of the second path thereof. The tape is moved relatively away from the crimping die when in crimping condition with the anvil and in engagement with a crimped terminal, to break the terminal away from the tape.

Abstract: An electrical terminal applicator is disclosed for crimping terminals onto wires, with the terminals being secured to a tape in a side-by-side relationship. An applicator ram is drivable in a first path through a working stroke towards, and a return stroke away from, a crimping anvil. A crimping die on the applicator ram cooperates with the anvil to crimp a portion of a terminal onto a wire during each working stroke of the ram. A track guides the tape in a second path which intersects the first path of the ram. A tape feeding system includes a shuttle member adapted for linear reciprocal movement alongside the second path of the tape in an advancing stroke towards, and a return stroke away from, the crimping anvil. The shuttle member has at least one tooth for engaging indexing apertures in the tape and incrementally advancing the tape on the advancing stroke of the shuttle member.

Abstract: A connector delivery system delivers an electrical connector component from a storage container to a processing station regardless of the relative orientation of the storage container to the processing station. The storage container contains a plurality of the connector components. A delivery conduit communicates between the storage container and the processing station. An air jet is located within the delivery conduit for effecting a pressure differential therewithin to create a vacuum to cause movement of the connector components in the delivery conduit in a downstream direction from the storage container to the processing station without the use of gravitational forces. A selector pawl upstream of the air jet feeds the connector components through the delivery conduit one component at a time in an incremental fashion. An orientation track between the selector pawl and the air jet is effective to deliver the connector components in a predetermined orientation.

Abstract: An automatically activated fire extinguishing apparatus mounted within a stove hood. The apparatus has a plastic bag liner enclosing a composition of fire extinguishing materials under pressure within a metal necked container. A pressure gauge housing having an interior channel containing an end of the plastic liner separates the necked container from an actuating header. A plastic nipple, located in a channel of the actuating header, closes an open end of an insert connected to the plastic liner. A fire sensitive device actuates a trigger which causes a cutting ram to sever the end of the nipple to permit exit of the fire extinguishing composition.

Abstract: A tool head for use in crimping a connector to a conductor, where the connector and conductor extend in a longitudinal direction. The tool head defines a crimping area about which a plurality of crimping nibs are mounted for movement into the crimping area so that the nibs act to indent the connector during a crimping operation of the tool head. Each nib is elongated and includes a connector indenting surface formed by a segment of a cylinder the axis of which extends transverse to the direction of elongation of the nib. In the preferred embodiment, four nibs are provided to define two opposing pairs of nibs. The nibs of one opposing pair are elongated generally transverse to the longitudinal direction of the connector, and the other opposing pair of nibs are elongated generally parallel to the longitudinal direction of the connector. Therefore, the nibs of each pair are elongated generally perpendicular to the nibs of the opposite pair.

Abstract: A paving mixture containing black asphalt which is changed to a color other than black by the addition of a limited amount of a coloring agent to the mixture, such as ferric oxide, to impart a permanent, distinctive color to the pavement without sacrificing any of the wearing qualities thereof. At the same time, the cost of the pavement is maintained within practical economic limits so that it may be used in the production of paved areas of limited extent, such as tennis courts, playgrounds, running tracks, parking lots, airport runways, etc. When the mixture is laid down in depths of one-fourth inch to twelve inches, the increased cost of the pavement is made up in a reasonably short period of time by the elimination of the need for painting the conventional black surface repeatedly, especially when the latter is subjected to extensive use and wear.
