Abstract: A web handling apparatus for splicing the terminal end of one roll of web stock to the lead end of a second roll of web stock in an uninterrupted feed to a machine. The first roll web is fed into the machine and a second roll web in parallel relationship to the first is guided by two turning bars laterally and again in parallel and overlying relationship to the first. Thereafter a splicer device joins the second roll to the first roll. The second turning bar is pivotally mounted on a vertical axis and movable vertically such that it can be moved from below the first roll web vertically upwardly and by pivoting about the vertical axis to a position whereat the second turning bar overlies the first roll web. Subsequently, the second roll web will overlie the first web in splicing relationship.

Abstract: There is disclosed herein apparatus which views a glass container from above while the container is rotated about its vertical axis. A source of light, preferably a laser, has its beam swept diametrically back and forth across the bottom of the container to be examined. The inclusion of a piece of stuck or fused glass in the container will create a light output in the form of a pair of concentric halos of light above the container finish. The halos are sensed by two concentric arrays of solar cells positioned above the container. The output of the solar cells is fed to logic and reject electronics for selected rejection from a line of ware moving along a conveyor, depending upon whether or not the container has a piece of stuck glass therein.

In the child-resistant mode, the resilient inner closure spring biases the outer shell into locking engagement with lugs formed on a cooperating container. A handling ring is provided for removing the inner closure for use separately as a snap cap. For this purpose, the inner closure includes an annular plug, and a short annular skirt arranged to engage the container rim.

Abstract: A batch process for recycling plastic container scrap is disclosed comprising the steps of reducing a container bearing an externally disposed label to granules, agitating the granules in hot water to remove the label material portion from the plastic portion, separating the hot water and label portion from the plastic granules, filtering and recycling the hot water into the batch while separating the waste label residue, remixing and reagitating until substantially all of the waste label residue is removed. Subsequently, the plastic granules are floated over a weir and collected in a dewatering station with the hot wash water recycled into a hot water reservoir. A major portion of the wash water is removed from the granules in the dewatering station. Substantially all of the residual wash water is removed in a drying station.

Abstract: An apparatus and a method for identifying defects in objects, such as glass bottles, utilizing data signals generated from a photodiode camera and light source. Event signals are generated when the magnitudes of adjacent data signals differ by an amount which exceeds a threshold level. Signals are also generated to identify the location of each event signal with respect to a corresponding photodiode and to identify during which vertical sweep of the object the event signal was generated to associate the event signal with a point on the object. The event signals are processed to identify defects. Events in proximity in the same sweep are identified as a string. Event magnitudes and totals in a string are compared with predetermined values to identify defects. Strings in proximity are identified as a blob. Event magnitudes and totals and blob width are compared with predetermined values to identify defects.

Abstract: An apparatus for displaying an output of an inspection device for objects such as glass bottles and the like is connected to a source of data signals each proportional in magnitude to the amount of light received from an associated point on the object being inspected. The data signals are inputs to a storage means and an adder for generating a signal representing the difference between each one of the data points and an adjacent one of the data points stored in the storage means. Each difference signal is compared with a threshold signal to generate an event signal when the magnitudes differ. The event signals are displayed as a two-dimensional representation of the surface of the object as if it had been cut and unwrapped. The operator can repeat the inspection utilizing different threshold values to optimize the defect detection performance of the inspection device.

Abstract: Apparatus for inspecting glass containers in which an indexing starwheel moves a plurality of containers in series through a plurality of positions or stations where the containers are physically and optically examined.One station, or position, is described in detail as the position where a glass container that is in a vertical position is rotated about its vertical axis by engagement of the finish thereof with a driven wheel. The container, as it is rotated, is viewed by a camera whose lens focuses the sidewall image of the bottle onto a vertical, linear array of light sensitive pick-ups in the camera. The camera is supported relative to the bottle handling system for adjustment up and down, back and forth and sideways so as to have the flexibility of viewing different size bottles. At the station where the sidewall of the bottles is to be inspected, a light source in the form of a tall housing is positioned in a vertical, annular recess of the starwheel.

Abstract: An improved composite material provides surfaces for handling hot glass charges and newly-formed glass articles without detrimental marring or marking of the same. The surface is formed on a relatively smooth metallic substrate by applying a primer coating of a first silicone resin to the substrate, applying a solventless second silicone resin binder coating over the primer, depositing a layer of granular heat-resistant carbonaceous material over the binder and allowing the binder to embed the carbonaceous material, and heat-curing the binder to provide a lubricated durable wear-resistant surface for handling hot glass charges or gobs as well as newly-formed glass articles.

Abstract: The present invention relates to method and apparatus for preheating pulverous materials, such as glass batch constituents, prior to their introduction into a melting furnace to increase the efficiency and output of the melting installation. The pulverous materials are passed downwardly by gravity through a shell and tube preheater including an interior exhaust chamber to vent the contained moisture from the heated pulverous material. The venting prevents moisture condensation and build-up of the pulverous material within the tubes and batch materials, especially in cooler areas, which can cause tube pluggage. The subject invention is of particular utility to the glass industry and especially glass melting furnaces, but is also applicable to other types of furnaces.

Abstract: A pressure-resistant thermoplastic container has a low center of gravity and a dimensionally stable seating ring zone of substantial strength. The center of gravity is lowered by reducing the weight of the finish and neck, and using a larger diameter for the main body to reduce the overall height while maintaining the desired internal volume. The improved design of the seating ring results in a thicker wall in the bottom end and, therefore, a stronger structure. The bottom end includes a sharp V-shaped structure having a concave inside wall and a generally convex outside wall joined at the bottom ends by a return portion. A convex central portion is connected to an upper end of the inner wall to define a central cavity and an extreme lower end of the outer wall is generally concave.

Abstract: This invention relates to a laminated vacuum pad, and method of making same, comprising a heat-resistant woven fabric substrate having a continuous heat and wear-resistant continuous coating thereon for handling hot glass articles, and the like, without marring same. The heat-resistant flexible vacuum pad is formed from a tightly woven fabric such as glass fibers with a continuous imperforate coating of organic-inorganic silicone resin containing a filler of heat-resistant carbonaceous material adapted to withstanding extensive repeated contact with newly-formed hot glass articles. The flexible laminated vacuum pad is preferably used as a facing material for a rigid structural member formed of metal.

Abstract: This invention relates to a thermoplastic, foam composition having enhanced heat-shrink capability by the physical intermixing therein of a minor amount of a second polymeric material having superior infrared absorbing properties. The intermixed composition is able to be foamed and formed into an oriented sheet adapted to fabricating heat-shrink tubular labels or sleeves, for example, having improved thermal contraction properties when subjected to infrared radiation. The subject composition is thus able to provide markedly improved heat shrinkage at lower temperatures than heretofore required for a variety of fabricated products. Polyethylene foam or polystyrene foam can be taken as the thermoplastic base material having a minor amount of a second polymeric material such as polyethylene terephthalate dispersed therein, the latter having a high absorbing capability for infrared energy.

Abstract: A method is disclosed for blow molding poly(ethylene terephthalate) preforms, such as injection molded parison, to achieve exterior surface embossed designs on blown containers without using profiled blow mold cavity walls. In the method, a raised profile is molded or otherwise formed on the exterior wall of the preform, defining a preform wall portion having embossed areas. Then the entire preform is heated to blowing temperature and it is also disclosed that when the raised portion is at the same time raised to a higher temperature the embossed design of the preform is opacified by crystallization without crystallizing the balance of the preform. Thereafter, the preform is blow molded under conditions such that the poly(ethylene terephthalate) material strain hardens in order to cause the different wall thicknesses to expand and stretch essentially proportionately.
