Abstract: A method and apparatus for operating a gas discharge display/memory panel having a pair of opposed electrode arrays. A pulsating potential sustainer wave form is applied to one electrode array while the other electrode array is maintained at the reference potential of the sustainer wave form, typically the system ground potential. The potentials are applied to the electrodes through switching circuits individual to the electrodes, each circuit including a normally turned on MOSFET and a feed through diode. The MOSFET and the diode are oppositely poled and connected in parallel between the potential sources and the associated electrode.

Abstract: A safety release pipe cap for emergency venting of fluids under excessive temperatures by melting out a replaceable portion. In one embodiment the replaceable portion is arranged to yield under excessive pressure differentials on its opposed faces. The cap is employed on tanks. A threaded ferrule is provided with a flange overlying the end of a pipe with which it is threadingly engaged to clamp the periphery of a separable disk of thermally fusible material against the pipe end. When the disk is of a yieldable plastic it functions as a seal gasket on the pipe end and will yield under pressure differentials to provide a visual indication of such differentials by material and wall thickness characteristics as well as the geometry of the disk. Temperature fusing can be controlled by these characteristics and particularly the melting temperature of the plastic.

Abstract: Apparatus for forming glass containers by the blow and blow process in which a parison mold having a plurality of cavities is centrally positioned relative to a pair of blow molds having a plurality of cavities. The parisons are formed with their necks down in the parison mold from a charge of glass delivered to each cavity. Vacuum is applied to the neck area of the mold to form the finish portion of the container. A neck pin is pulled and air under pressure is fed to the interior of the area from which the neck pin is drawn to expand the glass within the parison mold at a continuous rate until the glass within the parison mold comes in contact with a baffle which closes the upper end of the parison mold. The parison mold is then opened and the parisons are transferred alternately from the parison mold to the blow molds where they are expanded into final shape.

Abstract: This invention relates to the inspection of glass ampules to determine whether or not a complete score line is present. A laser beam is directed to the point on the ampule where a score line would be located. The laser beam is reflected in a diffuse or specular fashion depending upon whether or not a score line is present. By detecting the amount of light which is diffusely reflected in a particular direction, determination of the presence of a score line is possible. The same inspection may be utilized to determine whether the constriction on an ampule is of the proper diameter.

Abstract: A method and apparatus are disclosed for injection molding tubular plastic articles around cylindrical core pins at a molding station, for cooling the articles while supported on the core pins, and for then axially stripping the articles from the core pins at an ejection station. The article stripping step is accomplished by a horizontally reciprocable carriage which is selectively moved into and out of vertical alignment with a set of core pins and molded articles positioned at the ejection station. Sectional gripping members on the carriage are radially closable when in alignment with the molded articles, to grasp the articles for their axial removal from the core pins upon the horizontal displacement of the carriage. The stripped articles may be held in a horizontal cantilever position between the gripping members during an operational dwell time for additional cooling subsequent to their removal from the core pins.

Abstract: Method and apparatus for handling a plurality of glass containers moving on a conveyor at spaced intervals to a coating application area where three containers as a group are simultaneously grasped about their side wall and retracted laterally from the surface of the conveyor. This group of containers is then moved through a 90.degree. arc such that the containers exhibit horizontal axes one above the other. After the articles are turned to the horizontal, they are moved into position between three heel and neck-engaging chucks carried by an indexible turret. The bottles are released to the chucks which are cam actuated in timed relationship with respect to the grasping means so that the grasping means will release the containers or bottles to the chucks. With the chucks holding the bottles in horizontal position, the turret rotates about a horizontal axis parallel to the axes of the bottles through an arc of 90.degree. and presents the chucks in a horizontal line at the bottom of the turret.

Abstract: A gas discharge device having at least one dielectric charge storage member the gaseous medium contacting surface of which consists of a low operating voltage material. The material is used in an amount sufficient to increase the operating life span of the device and/or stabilize the operating voltages of the device. An interface and addressing means is connected to a pair of opposed electrode arrays to energize a plurality of discharge cells, each cell including proximate electrode portions of at least one electrode in each opposed array, said dielectric charge storage member insulating at least one of said proximate electrode portions from said gas. A cell presents a capacitive impedance to a voltage pulse applied by the interface and addressing means to the electrode portions to generate a relatively slow rise time leading edge on the voltage pulse for improved addressing of the cell when the electrode arrays are serially addressed.

The containers to be inspected are brought into the starwheel with the encircling members opened. Upon closing of the encircling members, containers may be indexed through a series of positions where they may be inspected for various defects.

Abstract: An improved home canning closure system is provided for a home canning jar featuring a plastic ring and a metal lid combination which is adapted to allow excess pressure to escape while preventing the escape of the contents from the container. The plastic ring includes an annular top panel portion and a skirt portion depending downwardly from the outer periphery of the top panel portion. The skirt portion incorporates threads on its inner surface to engage threads on the external neck of the home canning jar. The plastic ring features a downwardly and inwardly directed annular sealing flange depending from its lower surface which forms a spring member to maintain a constant force to bias the metal lid into sealing engagement with the upper rim on the home canning jar.

Abstract: A method for the manufacture of plastic containers. In a first embodiment of the invention a tubular length of thermoplastic material is severed from an extruder and blown into a preform shape in a movable preform mold. After completion of the cycle, the preform mold opens and returns to the extruder for a new section of material. The preform shape remains in the location where it was formed. Return of the preform mold moves the previously completed preform shape into registry with a conditioning mold. At this location, it is grasped by an indexable neck clamp. After completion of the thermal conditioning provided by the conditioning mold, the preform shape is indexed to a final shape mold where it is given its final configuration. The completed container is then indexed to a removal station for ejection from the forming process.
