Abstract: Apparatus is shown for mixing and dispensing an epoxy adhesive. An epoxy resin and its associated curing agent are simultaneously loaded from separate cartridges into a length of flexible PVC tubing, part of which is contained between a rotor and a stator. Bearings, mounted rotatably about the rotor, engage and travel along the tubing as the rotor is revolved, each bearing compressing the tubing at its point of engagement. The tubing, repeatedly compressed and released by each bearing in succession, kneads the epoxy resin and curing agent into a homogeneous mixture. From the tubing, the epoxy mixture is deposited on a moving carrier tape and forms a continuous bead. Downstream, a control tape is spaced apart from the carrier tape and moves in the opposite direction. As the bead encounters the control tape, the control tape removes part of the bead material from the carrier tape and plastically forms the remaining mixture into a film of a uniform thickness substantially less than the bead diameter.

Abstract: The golf club head has a metal face plate, vertically spaced horizontal fins extending rearwardly from the back side thereof, and a central vertical rib between each pair of fins. Weight-carrying inserts are threadedly mounted in the face plate and also extend rearwardly from the back side of the face plate. Molded about the fins, ribs and inserts is a plastic material in the form of rigid or structural foamed polyurethane.

Abstract: The golf club has a head of composite construction which includes a specially configured metal insert encased in a plastic matrix. The insert comprises an aluminum or magnesium face plate, relatively thin corrugated ribs or plates on the same metal extending rearwardly therefrom, and a transversely disposed block of lead cast onto the rear ends of the ribs or plates, the lead block containing therein a stack of individually removable heavy discs, preferably of a tungsten alloy, that further increases the mass at the rear of the insert. The face plate and corrugated plates, which are of aluminum or magnesium, constitute a relatively low density metal, but the plastic matrix, which is molded about the insert, is of a much lower density, the plastic constituting rigid or structural foamed polyurethane.
