  • Patent number: 10258842
    Abstract: A golf club head includes a metallic section, a polymeric section, and an adhesive material. The metallic section defines an opening and the polymeric section extends over the opening. The adhesive material is disposed between the metallic section and the polymeric section to form an adhesive joint therebetween. The adhesive joint has an adhesive retaining strength configured to inhibit the polymeric section from being detached from the metallic section when the adhesive material is at least partially cured. The metallic section and the polymeric section are also mechanically engaged with one another to form a mechanical joint therebetween having a mechanical retaining strength configured to inhibit the polymeric section from being detached from the metallic section. The adhesive retaining strength of the adhesive joint, alone, is greater than the mechanical retaining strength of the mechanical joint, alone, only when the adhesive material is at least partially cured.

  • Publication number: 20150100032
    Abstract: An information bearing septum viewable under radiographic imaging is formed by molding a septum base to have a depression with a given configuration and molding a one-piece solid radiopaque material insert having the same given configuration. The radiopaque insert is mounted to the cavity formed by the depression at the septum base. The top of the septum is then covered by a silicone layer that bonds to the septum. The finished septum is adapted to be fitted to a reservoir housing of a subcutaneous implantable portal. In place of the solid insert, the septum may be formed by placing on top of the septum base a one-piece top layer impregnated with a radiopaque material that has an integral hanging insert that fittingly mounts into the cavity formed by the depression at the septum base.

  • Publication number: 20150071626
    Abstract: A nozzle heater assembly coupled to a hot runner nozzle includes a heater support made of at least two support segments spaced apart by a gap. A heater element secured to both support segments is configured to limit the gap between the two segments. The nozzle heater assembly to be coupled to a hot runner may also include in other applications a heater support formed of a single piece and configured as a hollow helical tube including at least two axial gaps. A heater element is secured to the helical tube, where the helical tube can be compressed or stretched axially to alter a clamping force generated when the helical tube and the heater are coupled to the hot runner nozzle.
