Abstract: A removable seat assembly for mounting on an all-terrain vehicle, which seat assembly is characterized by a base plate frame for mounting on an ATV and receiving a fixed or rotatable pedestal or a pedestal having a rotatable pedestal flange, and a seat attached to the pedestal or the pedestal flange. The base plate frame is designed to permanently or removably weld, clamp or bolt on the utility rack of an all-terrain vehicle or mount on a seat slide, and a swivel mechanism may be interposed between the seat pedestal and the seat or between the seat pedestal and the base plate frame or seat slide to facilitate rotation of the seat with respect to the base plate frame and the all-terrain vehicle. In another embodiment a pair of support arms extend upwardly from a support arm mount secured to the rotatable seat, pedestal or pedestal flange and terminate in a top frame carrying a cover to protect and camouflage the occupant of the seat.

Abstract: The present invention relates to a process for forming glass-ceramic tiles. Fly ash containing organic material, metal contaminants, and glass forming materials is oxidized under conditions effective to combust the organic material and partially oxidize the metallic contaminants and the glass forming materials. The oxidized glass forming materials are vitrified to form a glass melt. This glass melt is then formed into tiles containing metallic contaminants.

Abstract: The present invention relates to a process of forming ceramic tiles having the appearance of tiles produced from clays. The process includes melting a material to form a glass melt, treating the glass melt to produce a solid glass product, grinding the solid glass product to produce glass particles having a particle size of less than 200 microns, mixing the glass particles with a first additive to form a glass powder mixture having a composition of 55 to 99 wt. % glass particles and 45-1 wt. % first additive, forming the glass powder mixture into tiles by dry pressing, where the tiles have a primary crystalline phase selected from the group consisting of nepheline, diopside, anorthite, wollastonite, melilite, merwinite, spinel, akermanite, gehlenite, crystalline phases based on iron substitutions in the crystalline phase, and mixtures thereof.

Abstract: A laser vibrometer which includes a laser, a laser beam splitter, two reflectors, an optical processor which includes two optical sensors, a digitizer for converting an analog signal into a digital signal, a flip-flop circuit, and a counter.
