A vehicle barrier apparatus includes a horizontal barrier component, a vertical barrier component, at least one rigid stabilizer beam having two end surfaces and at least one elongated side surface. One end of the stabilizer beam is affixed to the vertical barrier component. The elongated side surface of the stabilizer beam is affixed to the horizontal barrier component to prevent rotational movement of the vertical barrier component. A lower surface of the horizontal barrier component is a friction-enhanced surface which creates a sliding friction interface upon contact of a moving vehicle with the vertical barrier component.

Expedient barrier apparatus

A configuration, all components of which are man portable in some embodiments, for holding panels to protect assets against external force and impacts from airborne projectiles. An open box-like stackable frame module holds panels along a side of the frame. Multiple frames are connected to construct a protective barrier, such as a wall. Frames include provisions for connection in a vertical configuration so as to allow stacking of the frames to increase the height of the barrier. A method of installing is also provided.

Transportable modular configuration for holding panels

A cementitious armor panel assembly including cementitious armor panel with ballistic and blast resistant properties attached to a frame structure to produce a protective structure. The cementitious armor panels have a continuous phase resulting from the curing of an aqueous mixture of an inorganic cement binder, an inorganic mineral filler having a particle size of about 150-450 microns, a pozzolanic mineral filler, a polycarboxylate based superplasticizer self-leveling agent, and water. The mixture may also contain alkanolamine, and acid or acid salt. Prior to curing, the continuous phase is reinforced with fiber uniformly distributed in the continuous phase before it is cured to form the panel. The panel may be reinforced with a skin attached to at least one surface of the panel.

Cement based armor panel system

A cementitious panel with ballistic and blast resistant properties having a core layer of ultra-high compressive strength composite and at least one skin layer. The panels can also be used in walls, ceiling and flooring panels which require high compressive strength for resistance to earthquakes and surfaces resistant to surface abuse such as in prison and other institutions. The panel core layer has a continuous cementitious phase resulting from the curing of an aqueous mixture, in the absence of silica flour, of inorganic cement binder, inorganic mineral filler having a particle size of about 150-450 microns, a pozzolanic mineral filler, polycarboxylate based superplasticizer, alkanolamine and acid or alkali metal acid salt; and water. The mixture may be uniformly reinforced with fiber added before curing. The cementitious core layer is then reinforced with the skin, such as fiber reinforced polymer, attached to at least one panel surface.

Cement based laminated armor panels

A self-leveling cementitious mixture with excellent flow properties and which hardens with a controlled rate of strength development to an ultra-high compressive strength composite composition for use in making articles such as cementitious armor panel with ballistic and blast resistant properties including: a continuous phase resulting from the curing of an aqueous mixture, in the absence of silica flour, of inorganic cement binder, inorganic mineral filler having a particle size of about 150-450 microns, pozzolanic mineral filler, polycarboxylate based self-leveling agent and water. The cementitious mixture may include alkanolamine, such as triethanolamine, and acid or acid salt, such as tartaric acid. The cementitious composition may be reinforced with reinforcing fibers, e.g. glass fibers, in an amount of about 0.5-6.0% by volume of the overall cementitious composition. The fibers are uniformly dispersed in the cementitious composition before it is cured to form a final cementitious armor panel.

Concrete structures and components with improved strength and toughness. A uniform mix of first constituents comprises: cement of Blaine fineness of 280-360 m/kg; sand at a mass ratio of 0.75-1.25 of the cement; silica fume at a mass ratio of 0.15-0.4 of the cement; silica flour at a mass ratio of 0.15-0.3 of the cement; and microinclusions at a mass ratio up to 0.35 of the cement. This is then mixed with a blend of second constituents comprising a specified amount of an HRWRA and an amount of water at a mass ratio of 0.2-0.35 of the cement. This is mixed sufficiently to form a uniform cement-based paste to which an amount of macrofibers at a mass ratio of up to 0.35 of the cement is added to yield a uniform product. Nanoinclusions may be added to improve crack resistance and increase density.

A portable nuclear material detector generally includes a scintillating fiber radiation sensor, a light detector, a conditioning circuit, a frequency shift keying (FSK) circuit, a fast Fourier transform (FFT) circuit, an electronic controller, an amplitude spectral addition circuit, and an output device. A high voltage direct current (HVDC) source is provided to excite the light detector, while a separate power supply may be provided to power the remaining components. Portability is facilitated by locating the components of the detector within a handheld-sized housing. When bombarded by gamma particles, the radiation sensor emits light, which is detected by the light detector and converted into electrical signals. These electrical signals are then conditioned and converted to spectral lines. The frequency of a give spectral line is associated with a particular radioactive isotope, while the cumulative amplitude of all spectral lines having a common frequency is indicative of the strength and location of the isotope. All or part of this information (identity, strength, direction, and distance) may be provided on the output device.

Portable nuclear detector

Minute amounts of material, such as a contaminant, are detected, classified and located using a single procedure that eliminates the need for using complex and sometimes redundant instrumentation setups, multiple (and sometimes overlapping) analytic processes, or both. In one embodiment, a series of processing steps enables one to detect, classify, and localize minute amounts of particular elements, e.g., contaminants, in material being tested. Data sets, suitable for characterizing components of samples at least spectrally and spatially, are collected from at least one uncontaminated sample of material (the 'baseline' or 'control') and a sample of material under test (MUT) that may contain contaminants. Comparison of these data sets, using the procedures of the present invention, enables ready classification of minute amounts of material in any sample. The present invention may be used for liquids, solids, and gases, with specific application to gels, pastes, hard powders, soft powders, films, inorganics, and pharmaceuticals.

Detecting, classifying and localizing minor amounts of an element within a sample of material

Minute amounts of material, such as a contaminant, are detected, identified and located using a single procedure that eliminates the need for using complex and sometimes redundant instrumentation setups, multiple (and sometimes overlapping) analytic processes, or both. In a preferred embodiment, a series of processing steps enables one to detect, identify, and localize minute amounts of particular elements, e.g., contaminants, in material being tested. Data sets, suitable for characterizing components of samples at least spectrally and spatially, are collected from at least one uncontaminated sample of material (the 'baseline' or 'control') and a sample of material under test (MUT) that may contain contaminants. Comparison of these data sets, using the procedures of the present invention, enables ready identification of minute amounts of material in any sample. The use of existing conventional procedures may require that multiple sets of data be taken or multiple processes be applied.

A mat for covering soil comprising a lower fabric layer, an upper fabric layer superimposed over the lower fabric layer, and a water absorbing material interposed between said lower fabric layer and upper fabric layer. The mat contains tubular segments containing fabric and hydraulically setting cement. The cover, when wetted, becomes ballasted by the absorbed water and the tubular elements harden to form rigid ribs that hold the mat in conformity with the surface of the underlying soil.

Camouflaged erosion control mat

Rigid composite laminates of paper and glass layers, suitable for use as ouflage, are provided. This combination of components allows for great versatility in the final design and utility. A strong bond is obtained between paper and a fiberglass layer due to formation of a resin-cellulose matrix which allows interbonding between the paper and fibrous glass. The composite laminates may include other coatings or signature control layers and can be used as simple appliques or construction materials. A method for preparing the composite laminates is also provided wherein the paper is treated to enhance porosity in the formation of the resin-cellulose matrix.
