Publication number: 20180369658Abstract: Ball striking devices, such as golf clubs, have a head that includes a face having a striking surface configured for striking a ball, and a body connected to the face and extending rearwardly from the face, with the body having a crown, a sole, a heel side, and a toe side, such that the face and the body combine to define an enclosed internal cavity. A damping member is connected to the body and includes a post extending inwardly into the cavity from an inner surface of the body, a first arm extending from the post toward the heel side of the body, and a second arm extending from the post toward the toe side of the body. The damping member is configured to produce a mass damping effect upon an impact on the face.Type: ApplicationFiled: August 21, 2018Publication date: December 27, 2018Inventors: David N. Franklin, Michael Wallens

Patent number: 8936460Abstract: An extrusion head for an extrusion apparatus can include a spider for supporting a central mandrel. A high volume reservoir can be mounted to the spider on a downstream side of the spider. The central mandrel can extend longitudinally into the high volume reservoir. The high volume reservoir can have an axially straight annular conduit with a length L and an outer diameter OD. The annular conduit can have an L to OD ratio of about 1:1. A set of dies can be mounted downstream of the high volume reservoir, whereby the high volume reservoir reduces pressure and promotes homogenization of molten polymer flowing therethrough, before reaching the set of dies.Type: GrantFiled: September 21, 2010Date of Patent: January 20, 2015Assignee: American Maplan CorporationInventors: John Michael Wallen, James W. Nixon, Bradley M. Eisenbarth

Patent number: 8758003Abstract: The extrusion head including a conduit with a central mandrel extending within the conduit for supporting an inner die portion of a set of dies that has inner and outer die portions. An upstream spider and a downstream spider are included, and each have webs supporting the central mandrel at axially spaced apart positions. The webs of the upstream and downstream spiders can have web portions that are axially offset from each other to promote mixing of polymer flowing through the conduit.Type: GrantFiled: September 21, 2010Date of Patent: June 24, 2014Assignee: American Maplan CorporationInventors: John Michael Wallen, James W. Nixon, Bradley M. Eisenbarth

Patent number: 8333580Abstract: A spider for an extrusion apparatus located upstream from a die, through which a profile is extruded. The spider can have an outer housing with a central flow passage therethrough. An inner hub can be positioned within the central passage for supporting an inner portion of the die. At least one spider leg can be secured to the outer housing and the inner hub, and support the inner hub within the central passage. The at least one spider leg can recess radially rearwardly outwardly in the downstream direction such that molten polymer flowing through the central passage flows around the at least one spider leg, separating and rejoining together earlier in inner radial regions close to the inner hub than in outer radial regions close to the outer housing for reducing spider lines on inside surfaces of extruded profiles.Type: GrantFiled: December 15, 2011Date of Patent: December 18, 2012Assignee: American Maplan CorporationInventor: John Michael Wallen

Patent number: 5030676Abstract: An improved unplasticized polyvinyl chloride composition for forming articles for exterior use such as house siding and window profiles includes a polymeric organic impact modifier, at least one thermal dehydrochlorination stabilizer, and an ultraviolet stabilization system. The ultraviolet stabilization system includes from about 0.2-15 parts by weight of the polyvinyl chloride resin of rutile titanium dioxide and less than about 5 parts by weight of the polyvinyl chloride resin of magnesium oxide. Inclusion of magnesium oxide in the unplasticized polyvinyl chloride composition permits the extrusion of ultraviolet resistant siding and window profiles including relatively low levels of titanium dioxide.Type: GrantFiled: July 14, 1989Date of Patent: July 9, 1991Assignee: Certainteed CorporationInventor: J.
