Abstract: An inexpensive, lightweight, strong and durable casting that has a surface appearance simulating carved stone, and is especially adapted for use as a transition between a brick or stone wall and window and door openings. Further, it provides architectural detail to building constructions, especially as a surround for window and door openings. The casting is produced from a mixture of graded aggregates and a resin binder, combined in predetermined proportions to make a soupy mixture that is cast in a mold. The mold is vibrated to cause migration of air bubbles away from the surface of the molded product, and to cause realignment and orientation of the aggregate materials in a way to enhance the structure and surface density of the product. After the casting has set, it is removed from the mold and cured and the surface is sandblasted to erode away some of the resin binder and portions of the aggregate at the surface to produce an appearance that is an accurate simulation of carved stone.

Abstract: This relates to a workpiece particularly a simulated raised panel door as used on furniture and kitchen cabinets. Such doors are fabricated from a single sheet of core material and have a panel section machined into its face. In certain specific instances it is desired that the corners of the machined panel section be square and at best of very low radii. Because of this corner design it is virtually impossible and definitely time consuming to machine such corners in volume. The problem is solved by using preformed corner plugs inconjunction with a machined core. The core is composed of standard fiberboard material with a panel section machined into its face and plug housings machined into the face of the core at the panel section's proposed square corners. The corner plug is composed of a plastic material formed in part to that of a typical woodworking plug of cylindrical shape and a square inside corner section formed into the face and edge of the plug.
