Abstract: Method and apparatus for providing a completely encircling coating of an organic polymeric material on a localized region of a glass container. At a coating station, a glass container is rotated through at least 360.degree.. During the rotation, a material application head furnishes fluid organic polymeric material to the surface of the localized region of the glass container which is to be coated. Stop members hold the application head a fixed distance from the localized region and a doctoring edge of the application head helps form a uniform layer or coating of the organic polymeric material completely encircling the localized region.

Abstract: An improved memory for a glass container inspection machine. In one common form of glass container inspection machines, the containers are indexed through multiple stations where they are inspected for various attributes. Rejection of defective containers can take place only after all of the inspections have been made. The information relative to a defective container is placed in a master-slave type flip-flop uniquely associated with a particular inspection station. Information is then shifted through a group of series-connected master-slave type flip-flops in synchronism with the movement of the container until the container, if defective, reaches a location where it can be rejected. The information is moved or clocked by a generated clock pulse that has a rise time that is faster than the information transfer time through the flip-flops.

Abstract: A convenience closure having a removable central panel. A convenience closure is attached to a can end to seal the can. The closure includes a removable central panel; a panel fold with an endless severing line formed in its upper surface; a chuck wall fold which has a nose portion that extends radially inwardly farther than the severing line and overlies the severing line; and a pull tab, attached to the central panel, which has a nose portion that extends to the severing line. The panel fold includes a nose portion that extends to a position adjacent to and under the severing line. To remove the central panel, the pull tab nose is depressed to break the severing line. Then, the pull tab is moved upwardly to complete the breaking of the severing line and remove the central panel. Breaking the severing line forms two sharp raw edges; one lies under the nose of the chuck wall fold and is thus protected. The other raw edge is formed adjacent the nose of the panel wall fold.

Abstract: An improved "bird-swing" detector which has a downstream rejection system. An optical type bird-swing detector inspects glass containers as they move therethrough on a conveyor. A container exhibiting a bird-swing defect causes generation of a rejection signal. An oscillator may be set at a frequency in synchronism with the travel of the containers. A wave-shaping circuit forms the output of the oscillator into square waves at the frequency of the oscillator. A flip-flop has one input connected to the rejection signal and another input terminal connected to the wave-shaping circuit. The flip-flop output is connected to a multi-stage shift register. The signal from the wave-shaping circuit clocks the shift register. The switching of the flip-flop is delayed to allow entry of any information therefrom into the shift register before the flip-flop is reset. A reject or defective container signal is clocked through the shift register in synchronism with the travel of a defective container on the conveyor.
