Abstract: A method and apparatus for manufacturing a crack repair product, and a method of repairing a crack using the product are disclosed. The material is made by heating and softening a bulk sample of direct-fire crack sealer material. The softened material is then extruded into a strand having a predetermined diameter. An anti-adherent material such as a polyethylene film is then applied to the extruded material, and the material is drawn along its length to reduce the diameter of the material to a desired diameter. In order to repair a crack, a length of the material is selected and has a diameter corresponding to the crack width. The material is packed into and near the top of the crack, and is then melted to permanently seal and repair the crack.

Abstract: The head of a golf putter has a body elongated in the longitudinal direction and having a striking portion with a strike face extending in a direction transverse to the longitudinal direction of the body. An extension of the longitudinal axis of the shaft of the putter passes through the center of mass of the head but the shaft itself is connected to the head by means of a connector member having a portion which extends upwardly from the head in a direction normal to both the longitudinal and transverse directions, and a second portion connecting the first portion with the shaft.
