Abstract: A "green" sheet manufacturing method and apparatus contemplates perforating the "green" sheet with through-holes as it is calendared, rolled or extruded by rollers. To this end, the rollers are each machined with punches of a length one-half the thickness of the "green" sheet and that mate with punches on the other. Any flash or diaphragm obtaining in the through-holes are removed by subsequently exposing the "green" sheet to new mechanisms providing fluid pressure or vibration, or spiking. The bosses or punches may be supplemented with enlargements and other bosses providing for pads and counterholes and grooves in the "green" sheet. The through-holes may be shaped to have a smaller diameter interiorly than at the outer edges to lock in place solder or other conductive media squeegeed into them. The locking action may be enhanced by slightly off-setting bosses or mating punches to produce through-holes whose top and bottom halves are slightly off-set.

Abstract: Conventional golf tees and markers are modified to provide golf club face and club face groove cleaners. The heads of tees and markers are formed square rather than round to provide straight edges for scraping the faces of dirtied golf clubs and with the edges intersecting to form sharp corners for insertion in club face grooves to facilitate eviction of the dirt therein. The stems of tees may be made of wood and the heads thereof of a molded material to provide superior cleaning capability.

Abstract: Apparatus for discharging sheets having skins on them and different patterns, characteristics, and properties. One or more rollers, belts, plates, or combinations thereof, having cavities and projections of desired patterns formed on their surfaces, pass through low pressure liquefied extrudable materials to be bathed thereby and pass by another surface(s). Heating or cooling is applied as appropriate to the roller(s), plate(s), belt(s), to form a skin on the extrudate and/or set same. A distributed low pressure, mixed orientation, low gas, liquefied extrudable material is generated using a vented barrel assembly and manifold mechanism. By using a dynamic moving die surface, bathed in a low pressure material chamber, rather than extrudable material forced through a fixed die opening as is normally done in extrusion processes, a product with low stress and one that exhibits isotropic properties results.
