A battery has anodes, cathodes, separators, and electrolyte. Particles of loose hydrated alkali aluminum silicate contact the anodes and cathodes and are immersed in the electrolyte, to enhance operability of the battery. The maximum dimensions of at least a majority of the particles are between about 5-10 mm, and they range in shape from spherical to irregular.

Battery with ceramic particles

A lightweight armor system providing blast protection and ballistic protection against small arms fire, suitable for use in helmets, personnel or vehicle protection, and other armor systems. A hard substrate is coated on the front surface with a thin elastomeric polymer layer, in which hollow ceramic or metal spheres are encapsulated. The coating layer having a thin elastomeric polymer layer with encapsulated metal or ceramic hollow spheres can be stand-alone blast protection, or can be added to an underlying structure. The glass transition temperature of the polymer is preferably between negative fifty Celsius and zero Celsius.

An apparatus and method for treatment of articles, using glass failure generated pulses. The apparatus and method is directed towards the hardening and compaction of a spherical article surrounded by a glass orb in a confined arrangement. The apparatus includes a striker having first and second opposing strikers for striking the glass orb from different sides of the confinement arrangement, to create an explosive reaction that pressure-treats the spherical article, thereby causing the hardening and compaction.

Apparatus and method for outer surface enhancement and compaction of a spherical structure using glass failure generated pulse

An apparatus and method for treatment of articles, using glass failure generated pulses. The apparatus and method is directed towards the hardening and compaction of a glass-covered elongated object that is impacted by a flyer plate having a shape that is complimentary to that of the elongated object. The flyer plate is propelled by, an explosive reaction to create the impact on the glass-covered elongated object. This results in an explosive reaction that pressure-treats the elongated object, thereby causing the hardening and compaction.

An apparatus and method for treatment of articles, using glass failure generated pulses. The apparatus and method is directed towards the hardening and compaction of an elongated cylindrical article surrounded by a glass sleeve in a confined arrangement. The apparatus includes a striker for striking the glass sleeve to create an explosive reaction that pressure-treats the cylindrical article, thereby causing the hardening and compaction.

Apparatus and method for outer surface enhancement and compaction of a cylindrical structure using glass failure generated pulse

An apparatus and method for hardening and compacting an inner face of a cylindrical opening of a structure. The apparatus and method is directed towards the hardening and compaction of an elongated cylindrical opening by surrounding the inner face of the cylindrical opening with a glass tube, and initiating an explosive volume expansion of the glass. This in turn, creates a compressive force that acts on the inner face to compact and harden the surface.

A composite article having blast and ballistic resistance suitable for helmets, personal protection and hard armor applications comprises a high-strain hardening elastomeric layer and a layer of continuous yarns having a tenacity of 15 grams per dtex and a modulus of at least 500 grams per dtex or an oriented polyethylene sheet layer having a modulus ten times greater in one direction than in another direction.
