Abstract: A composite for constructing an article which is composed of a nonmetallic substance as represented by igneous rock of different particle sizes which are compacted and then surrounded by a solidified plastic resin. In a preferred manner, the igneous rock material is a selected type of basalt with the basalt particles being of different mesh sizes to be compacted into a mold. After compaction, the plastic resin as represented by an epoxy resin is introduced into the mold so as to displace air from any voids surrounding the basalt particles and to surround them with a resin which later solidifies. A novel resin delivery system is also presented.

Abstract: An article of insulation and a method for making same. Outer sheet-like elements (22,24) of elastic deformable material are secured by adhesive to a base element (20) of rigid deformable material in a particular pattern which defines unbonded areas which are each bounded entirely by adhesive. The combination of the two outer elements (22,24) and the base element (20) is then deformed, following which the base element (20) retains its deformed shape while the outer elements (22,24) spring back to their original shape, leaving voids between the base element (20) and the outer elements (22,24) in which there is a partial vacuum.

Abstract: A protective diffusion barrier for metalized mirror structures is provided by a layer or coating of silicon nitride which is a very dense, transparent, dielectric material that is impervious to water, alkali, and other impurities and corrosive substances that typically attack the metal layers of mirrors and cause degradation of the mirrors' reflectivity. The silicon nitride layer can be deposited on the substrate before metal deposition to stabilize the metal/substrate interface, and it can be deposited over the metal to encapsulate it and protect the metal from corrosion or other degradation. Mirrors coated with silicon nitride according to this invention can also be used as front surface mirrors.
