An improved upward flow constructed wetland cell for treatment of water contaminated with chlorinated aliphatics is disclosed. The improvements include adding ammonia-oxidizing microorganisms to the methane-oxidizing microorganisms already present in an oxygenated root zone and adding improved pore-water sample chambers for measuring the performance of the constructed wetland cell.

Upward flow constructed wetland for treatment of water contaminated with chlorinated aliphatics

The present invention comprises a reflective surface used in conjunction with an aiming device that provides the user targeting information on a surface directly on the aiming device. The reflective surface is moveably mounted directly behind the aiming device, where a user's eye would normally be positioned. In this configuration, a user, positioned at a point not directly behind the aiming device or system being used, may move the mirror to an angle appropriate to see where the system is being aimed, as indicated, on the surface of the aiming device.

Aiming device

A pyrotechnic, molten metal jet torch which employs a loose pyrotechnic ster powder such as (1) magnesium powder, or an intimate mixture of (2) Mg and CuO, (3) Mg and Fe.sub.2 O.sub.3, (4) Mg and Co.sub.3 O.sub.4, (5) Al and CuO, or (6) Al and Fe.sub.2 O.sub.3 powders which are capable of being ignited by a conventional military incendiary grenade fuse and which generated enough heat to ignite pyronol pellets which are pressed from an intimate powder mixture of (1) nickel, (2) metal oxide, (3) a component selected from the group consisting of (a) aluminum and (b) a mixture of at least 50 weight percent aluminum and a metal that is magnesium, zirconium, bismuth, beryllium, boron, or mixtures thereof.

Pyronol torch

A composite armor shield comprising alternating layers of steel and a polymeric material which is either a polymethyl methacrylate of the general formula ##STR1## or a polycarbonate of the general formula ##STR2##

Composite shields

The invention is directed to a Pyronol torch and holder device for provid quick and efficient attachment of the torch to a barrier target (flat, curved, or irregular shape) that is made of steel or magnetic steel alloys. The device provides for attachment to the target and for holding a cutting torch containing pyrotechnic material at a predetermined standoff distance from the surface of the target for proper operation of the torch and for permitting escape of products of combustion to minimize liftoff forces on the holding device tending to lift it from the target to which it is attached.

Apparatus for attaching ordnance to barrier targets

A molten metal-liquid explosive device comprising:
