Abstract: A porous refractory in the K2O—SiO2—B2O3 system is formed by chemical direct foaming by heating to over 600° C., resulting in adherent black or white foam. The foam can function as highly porous thermal insulation, a high or low thermal emissivity surface, as a sealant for deteriorated refractory surfaces, as a filler for pockmarks/holes/gaps or as a bonding agent for parts with large gaps between them.

Abstract: Bulk paint and ceramic powder systems, methods of forming same, and methods of forming a flexible ceramic coating on a metal substrate are disclosed. The systems may include a ceramic composition having between 2 to 30 weight percent of an alkali metal oxide, such as K2O, Na2O, and Li2O or mixtures thereof, between 10 to 74 weight percent SiO2, and between 23 to 79 weight percent B2O3. Additives that are nonwetting with molten metals, such as boron nitride, provide durable coatings for metal processing operations. The ceramic composition may include less than 5 weight percent additional metal oxides. The bulk paint system further may include water and a cellulosic suspension agent to form a bulk paint. The ceramic powder system may be processed to form a uniform powder. The bulk paint or uniform powder may be applied to a metal substrate, such as a ferrous metal substrate, dried, and heated to form a flexible coating on the metal substrate.

Abstract: A non-aqueous solution-suspension of R2O—SiO2—B2O3 comprises in the dry state a composition of 2 to 30 weight percent R2O, wherein R2O is an alkali metal oxide; between 10 to 74 weight percent SiO2; and between 23 to 79 weight percent B2O3. Non-aqueous solution-suspensions are used to blend to give a liquid paint which, on drying, contains the composition within the range given above in the R2O—SiO2—B2O3 system. Non-aqueous bulk liquid and aerosol based spray paints are provided, with or without Boron Nitride additions, to allow the formation of tough, flexible coatings onto ferrous metals after bake-on.

Abstract: A dry composition comprising 2 to 30 weight percent R2O (wherein R2O is an alkali metal oxide, K2O, Na2O, Li2O or mixtures thereof); 10 to 74 weight percent SiO2; and 23 to 79 weight percent B2O3. Aqueous solutions and/or colloidal suspensions (thus referred to as solution-suspensions) are used to blend to give a liquid-binder which, on drying, contains the composition within the range given above in the R2O—SiO2—B2O3 system. The dry composition is mixed with sufficient H2O to form the solution-suspensions. As described herein H2O may also be present in some additional additive.

Abstract: Disclosed are various embodiments for a self-contained power supply. A container is configured to be placed separate from a powered structure, such as a house or place of business. The container houses a power supply unit that includes a battery bank and an inverter. The battery bank receives multiple charging currents from multiple power sources, such as a grid power source and an auxiliary power source. The inverter uses electrical energy stored by the battery bank to provide an output current to the powered structure.
