Abstract: Described herein are embodiments that provide a device model to the data structure, or management protocol, of an element management system (EMS) to support new and non-standard devices and incorporate such devices into the EMS for management of the devices. The device model employs device plug-ins for the EMS to gain access to the device without the need to make modifications in the EMS server core.

Abstract: A method for pollutants using an iron-impregnated, carbon-coated silica sand with the iron containing between to and 16 percent silicon. The invention provides an improved method for performing remeditation of pollutants by dissolved metal reactions while minimizing interferences caused by oxide fouling from oxygen in the water or in the atmosphere. The invention further provides an inexpensive media with high surface area for adsorptive fixation and reductive treatment that yields higher than anticipated reaction kinetics utilizing only low concentrations of iron in the media.

Abstract: The present invention presents an improved method and apparatus for liquid entrainment by a two-phase flow system. The present invention provides an apparatus that recovers liquids by entrainment without experiencing deadhead conditions, choking or dry recovery due to fluctuations in the elevation of the liquid level. The apparatus provides self-regulated two-phase recovery of gas and liquid by construction design, thus eliminating the need for manual adjustments or electronically controlled devices. The enhanced venturi effects of the present invention enhance liquid lift while maintaining the gas recovery point above the liquid at all times to eliminate deadhead conditions.

Abstract: A coater head for contacting a liquid coating material with a traveling web of paper or fabric. The coater head includes at least two chambers and an extended outflow bubble to increase the zone of contact between coating liquid and the traveling web. Improved, coating quality also results from controlled flow characteristics through the coater head having a feed zone length-to-depth ratio of four or more.

Abstract: An applicator head is positioned beneath a backing roll and has a housing divided into three sections. A first coating pond is defined between an overflow barrier and a first wall. A converging plate extends between the first wall and a second wall, and converges toward the substrate, and a second pond is defined between the plate and an end wall. Coating is introduced to both ponds. A low pressure cavity is defined beneath the converging plate and between the first wall and the second wall. The cavity opens to the second pond, and draws air and excess coating from the second pond. The substrate is prewetted as it passes through the first pond, and coating deprived of entrained air is applied to the substrate in the second pond. Coat weight uniformity and increased machine speeds are thus achievable.

Abstract: An applicator head is positioned beneath a backing roll over which a substrate can be drawn. The applicator head has a housing which contains a pond of coating material between an up machine overflow lip and a down machine extraction plate or premetering plate. Coating material at a relatively low velocity flows into the pond adjacent to the overflow lip. The premetering plate extends radially from the coating inlet to a position proximate to and converging with the backing roll, where it premeters the amount of coating applied to the substrate. The premetering plate preferably has a plurality of holes through which coating and air are drawn. A metering element is spaced downstream of the premetering plate, and a low pressure area is constructed therebetween. Air and coating are drawn from the low pressure area through a valve, and the pressure thereby controlled.

Abstract: Air entrained within the pond of a coating applicator is influenced toward a designated region for removal. The region is formed by a recessed air collector which sets up a high-recirculation, low-pressure zone within the pond. Entrained air bubbles migrate to the collector. The collected air and excess coating is drawn out of the collector cavity by a plurality of perforations which discharge to a collection cavity at a lower pressure or partial vacuum. The collector structure may be employed in various coater/size press configurations.

Abstract: A backing bar assembly has a plurality of positively positionable backing bar units which are retained within an inverted U-shaped housing by semi-cylindrical lifters which are adjusted by adjustment screws connected to the housing. Each backing bar unit has concave end surfaces which face the adjacent backing bar units. A pair of backing bar units is engaged by the semi-cylindrical convex surfaces of a lifter and may thus be vertically positioned by rotation of the adjustment screw. By adjusting two backing bar units at a single screw, dramatic discontinuities between backing bar units are avoided. An inflatable resilient seal is engaged by all the backing bar units and extends between the units and the blade to transmit force to the blade to retain it in a desired position.

Abstract: A battery cell circuit provides a battery cell having a positive terminal and a negative terminal, and bypass circuitry for allowing current to flow around the battery cell should it fail open. The bypass circuitry includes a first plurality of diodes connected in series between the positive terminal and the negative terminal, with those diodes connected with their forward direction from the positive terminal to the negative terminal, to provide a path for charging current around an open circuit battery cell. Two series sets of parallel diodes are connected between the negative terminal and the positive terminal, with their forward direction from the negative terminal to the positive terminal to provide a bypass path for discharge current to flow around the battery cell in the event if fails open and the bypass circuitry is preferably packaged in a hermetically sealed hybrid module.

Abstract: A penetrating member for a projectile comprising a cylindrical mass body e from a high-density material and formed with a hardened front end in the form of a concavely curved scoop with an outstanding spike in its center. One end of a tubular liner abuts the scoop, the liner being made of an easily deformable, material. When the liner hits a target, the liner is forced back along the curve of the scoop and out the center of its tubular form as a high-velocity, target-penetrating jet of material.
