A glass composition is disclosed which is formed from a mixture comprising one or a plurality of natural mineral zeolites and having a melting point in the range of from about 1000. degree. to about 1500. degree. C. The glass compositions of this invention can be formed into various glass articles, including flat glass, glass containers, glass fiber and glass foam.

An associative data processor including a spin glass type amorphous magnetic film has input areas, output areas, and "hidden" or associative areas. A coil provides selective magnetic biasing, and lasers provide selective digital input to the input and output areas, which are intercoupled by the associative areas. Following input of a number of digital patterns to the processor, and "learning" by heating the associative areas, an incomplete input pattern may be applied, and the complete pattern read by sensing the polarization of reflected polarized light from the output areas.

A process for making a porous ceramic composite with a bimodal pore size distribution includes the steps of mixing an organosilicon precursor, an alcohol, water, a catalyst, granules, particles, whiskers or powders of a fumed silica and granules, particles, whiskers or powders of a ceramic material and a combustible material having a diameter in a range of 500 angstroms to 500 microns to form a mixture, pouring the mixture into a mold, allowing the mixture to gel form a ceramic composite and drying the ceramic composite. The process also includes the step of heating the ceramic composite in either air or oxygen to burn away the combustible material. The organosilicon precursor is selected from a group consisting of tetramethoxysilane, tetraethoxysilane, tetrapropoxysilane and tetrabutoxysilane. The alcohol is selected from the group consisting of methanol, ethanol, propanol and butanol.

Amorphous ferroelectric materials are formed by a sol-gel type process and the ferroelectric properties stabilized by complete hydrolysis and polycondensation, and extraction of residual organic materials, preferably by heating at temperatures below the temperature at which crystallization may occur. Stable solutions of metal alkoxides are prepared by reacting or dissolving a metal alkoxide in alcohol such as absolute ethanol. The solution may be spincast on essentially any substrate, conductor or nonconductor, crystalline or amorphous, transparent or opaque, and even including plastics. Hydrolysis and polycondensation occur in situ to deposit an amorphous ferroelectric film. Residual alcohol is extracted by heating below the temperature at which crystallization occurs. Such films show P-E hysteresis loops and pyroelectric current. Such ferroelectric thin films are useable in electronic, opto-electronic and optical devices.

Solid animal excreta, such as solid livestock excreta, solid human excreta and solid poultry excreta, is converted to useful products by particulating the excreta and heat treating it in a closed heating zone at about 200. degree. C to about 1000. degree. C for a time sufficient to volatilize a portion thereof and provide the solid residue with a carbon content of about 1% to about 80 weight percent. The volatilized portion can be withdrawn from the heating zone and separately recovered by condensing the condensibles. This consists of an aqueous and a non-aqueous portion. The non-aqueous portion of the condensate is oleaginous in the form of an oil, grease or wax containing nitrogenous substances and is useful for a variety of purposes. The aqueous portion is rich in nitrogen and is useful as a fertilizer. The solid particulate residue can be employed as a foaming agent or filler for glass products and as a coloring agent or pigment in inks, paints and rubber products.

A method is provided for preparing piezoelectric fibers by concentrating a solution containing at least two metal alkoxides, a carboxylic acid and lead alkanoate to form a viscous liquid. The viscous liquid is drawn into amorphous fibers and the fibers are calcined and sintered to form the crystalline piezoelectric fibers.
