International Classification:

G01I 100

US Classification:

2504911, 250361 R

Abstract:

A fiducial beam monitor includes a patterned diode layer on a semiconducting substrate. An electrical field between the diode (or diodes) on the diode layer and the semiconducting substrate modulates the size of the depletion layer formed by the diode or diode. A high energy beam incident upon a diode on the diode layer produces a greater current than a high energy beam incident upon a non-diodic region of the same layer. In use, the beam monitor is typically fixed to the backside of a workpiece such as a semitransparent membrane being patterned by a focused high energy beam that is translated with respect to workpiece and attached monitor. The changes in current during translation are then correlated with the position of the beam with respect to the pattern on the diode layer.

Abstract:

A dissolving tank for dissolving a large amount of gas in a liquid and including a generally horizontally disposed tray (28) (29) mounted within the tank (2) (21) to divide the tank (2) (21) into an upper reaction zone (36) and a lower discharge zone (38). The tray (28) (29) has formed therein both a central opening (34) (35) for fluid communication between the discharge zone (38) and the reaction zone (36) and peripheral openings (32) (33) which allow any liquid which collects on the tray (28) (29) to flow from reaction zone (36) to discharge zone (38). The dissolving tank further includes liquid feed means (10) positioned within the tank (2) (21) below the tray (28) (29) to discharge liquid upwardly through the central opening (34) (35) of the tray (28) (29) and into the reaction zone (36). The dissolving tank further includes liquid distribution means (14) mounted within the tank (2) (21) above the tray (28) (29) and having flared sidewalls (15) and a vertically-oriented distribution orifice (16). The distribution means (14) is positioned so that a portion of the liquid discharged upwardly from the feed means (10) impacts on the flared sidewalls (15) and is distributed as droplets within the reaction zone (36) and another portion of the liquid discharged from the feed means (10) passes upwardly through the distribution orifice (16) toward the top (3) of the tank (2) (21).

International Classification:

F42B 1/028
F42B 1/032

Abstract:

Provided herein are shaped charges for focusing a fluid mass and related methods of using the shaped charges for disruption of an explosive target with a spherical projectile. The shaped charge comprises a plastic shell having a special geometric shape configured to support a shape-conforming explosive. A cylindrical plastic body has an interior volume for containing a fluid and the plastic shell. The plastic body closed distal end has a geometric shape that is substantially matched to the shape of the plastic shell. Metal spherical projectiles having an outer layer of metal selected to have an effective density matched to the fluid provide advantageous target disruption capabilities.

International Classification:

C10L 5/44
C10L 5/36

Abstract:

A process for cleaning and beneficiating biomass is described which may allow removal of entrained salts and light volatiles from biomass materials. The process may also minimize energy use through capturing steam and flue gases for re-use. The process may generally comprise the following steps: prewashing and/or preheating a biomass, pressurizing the biomass in a steam explosion vessel, rapidly depressurizing the steam explosion vessel, releasing the steam from the steam explosion vessel entrained with fine lignin-enriched particles into a cyclone-type gas expansion vessel, routing the steam from the gas expansion vessel to the input hopper, subjecting the biomass to a second washing step, mechanically removing a portion of the water from the biomass, and evaporatively heating the biomass.

After the biomass has been steam-exploded, it may be washed and used as an engineered soil.
