Apparatus and method for treating a substrate, for example texturing a substrate. In some embodiments, a masking material is applied to a surface of the substrate in a predetermined pattern, the surface thereafter contacted with an etchant that removes the masking material. Contacting the surface with the etchant produces multiple co-located textures. In other embodiments, the masking step can be eliminated, and the etchant is applied in a predetermined pattern to produce multiple co-located textures. In still other embodiments, the substrate has a chemical composition, and the substrate is exposed to a leachant that leaches at least one constituent of the chemical composition to produce a substrate with a varying chemical composition at the substrate surface.

Multi-layer structure and method of making same

A process for producing glass laminates including at least one sheet of glass having a thickness not exceeding 1.0 mm with reduced optical distortion and shape consistency. A pre-laminate stack of two glass sheets and a polymer interlayer are stacked between two buffer plates that are formed nominally to the desired shape of the laminate mold. The pre-laminate stack is held between the buffer plates while a vacuum is applied to the edges of the pre-laminate stack and the stack is heated to a temperature somewhat above the softening temperature of the interlayer to de-air and tack the interlayer to the two glass sheets forming the desired shaped laminate with reduced optical distortion.

The disclosure is directed to a transparent armor laminate having a glass, glass-ceramic or ceramic strike face layer, one or a plurality of glass, glass-ceramic ('GC'), ceramic ('C') or polymeric (&#x201c;P&#x201d;) backing layer behind the strike face layer, one or a plurality of spall catcher (&#x201c;SC&#x201d;) layers behind the backing layer(s), and a thin cover glass layer laminated to the strike face, the thin layer being the first layer to be impacted by any incoming projectile or debris. The cover glass has a thickness &#x2266;3 mm. In another embodiment the cover glass thickness is &#x2266;1 mm. Additionally, a defrosting/defogging element is laminated between the cover glass and the strike face.

A method for fabricating electrode structures within a honeycomb substrate having a plurality of elongated channels is provided that is particularly adaptable for producing an ultracapacitor. In this method, the nozzle of a co-extrusion device simultaneously feeds a current collector along a central axis of one of the channels while simultaneously injecting a paste containing an electrode material so that the interior of the channel becomes completely filled with electrode paste at the same rate that the current collector is fed. Such co-extrusion as performed simultaneously at both sides of the ceramic substrate to rapidly form electrode structures within substantially all the channels of the substrate. The resulting ultracapacitor is capable of storing large amounts of electrical energy per unit volume in a structure which is relatively quick and easy to manufacture.
