A transparent laminate structure is provided that includes a front section, a rear section, and a middle section securing the front and rear sections to one another with a gap therebetween. The front section has a strike face formed of an impact resistant layer and a polymer backing layer bonded to the impact resistant layer by an interlayer. The rear section has a forward face comprising at least one polymer layer. The front and middle sections can form an integral subassembly.

Light weight temperature resistant transparent laminate structure

A multilayer armor is provided that includes a first rigid layer, a second rigid layer, and an interlayer securing the first and second rigid layers to one another. At least one of the first and second rigid layers can include a plurality of regions with a physical or material property that varies between the regions. The interlayer can have a force-extension ratio of 5,600 psi/in or less. The interlayer can have a physical or material property that varies within the interlayer.

Multilayer armor

The shaped composites of the present disclosure have metal powder bonded with glass powder. This feature provides the advantages of metal, metal powder, or glass composite materials, without suffering from the disadvantages. The composite is prepared with simple sintering methods, and can easily be formed into any number of desired shapes with dimensional characteristics and ingredients suited to a particular application.

Glass-bonded metal powder charge liners

The invention relates to a lightweight transparent armor laminate comprising layers of borosilicate glass, layers of transparent glass-ceramics and a polymer spall layer of polycarbonate and/or polymethyl methacrylate. The layers are bound by polyurethane and/or polyvinylbutyral interlayer films.

Lightweight transparent armor window

The invention relates to aluminoborosilicate-based glasses suitable for use as a solid laser medium. In particular, these aluminoborosilicate-based laser glasses exhibit broad emission bandwidths of rare earth lasing ions. Although not entirely understood, the broadening of the emission bandwidth is believed to be achieved by the presence of significant amounts of lanthanide ions in the glass matrix. In addition, because of the high values of Young's modulus, fracture toughness and hardness, the rare earth aluminoborosilicate glass system according to the invention is also suitable as transparent armor window material.

Rare earth aluminoborosilicate glass composition

The invention relates to a process and apparatus for forming a particulate composition, especially a particle glass composition, through the use of shock waves. A nozzle element is utilized having inlets for introduction of cold and heated gas and a delivery tube for introducing molten material. Through the introduction of the cold and heated gases, droplets are formed from a molten stream, a cone-shaped standing shock wave is formed, and shock waves are formed via a modified Hartmann-Sprenger chamber, the shock waves impinging on the droplet stream to break up the larger droplets.

Method and apparatus for spray-forming melts of glass and glass-ceramic compositions

The opto-ceramics and optical elements of the present invention are transmissive to visible light and/or to infrared radiation. They consist of a crystal combination in which individual crystallites have a cubic structure of the type YOand are made from InOor a mixture of oxides of the type XOin which X=Y, Lu, Sc, Yb, In, Gd, or La. Also mixtures of XOwith oxides having different stoichiometries, such as zirconium and hafnium oxide, are possible, as long as the cubic structure of the opto-ceramic is maintained. The optical elements prepared from the opto-ceramics are particularly suitable for mapping optics, such as objectives having reduced chromatic aberrations, in particular with approximately apochromatic mapping behavior. The optical elements of the present invention may be used in lens systems in combination with lenses of glass, but also with other ceramic lenses.

The optical elements are made from an opto-ceramic material that is characterized by high density, transparency for visible light and IR, high refractive index, high Abbe number and outstanding relative partial dispersion. Mixed oxides are sintered to obtain the opto-ceramic material. The mixed oxides contain zirconium oxide and hafnium oxide mixed with one or more oxides of yttrium, scandium, lanthanide elements, and optionally mixed with one or more of SiO, NaO, and TiO. Alternatively the mixed oxides contain zirconium oxide and hafnium oxide mixed with CaO and/or MgO and optionally mixed with one or more of SiO, NaO, and TiO. In addition, the mixed oxides can also include one or more oxides of Al, Ga, In, and Sc; optionally one or more oxides of yttrium, some lanthanide elements; and optionally one or more of SiO, NaO, MgO, CaO, and TiO.

Optical elements and imaging optics comprising them

A hot forming unit or debiteuse for plate glass production, with a noble metal box or frame encompassed by and contained in a highly heat-resistant ceramic frame and having a drawing slot matched to a cross section of a plate glass sheet to be produced. The dimensional integrity of the drawing slot of the noble metal frame is assured because the ceramic frame is constructed of longitudinal components and lateral components, where the longitudinal components of the ceramic frame and the longitudinal legs of the noble metal box rest against one another and are held so that they can still move axially against each other in a limited fashion. The longitudinal legs of the noble metal box are held in a stretched position by tension springs.
