Abstract: An improved method and apparatus for optical determination of the orientation of a garment workpiece (12) by locating a seam (18) on a stationary workpiece formed from at least two sub-pieces sewn together along that seam. The device consists of a light emitting surface (14) on which the workpiece is placed, so that light is transmitted at a first intensity through the surface, at a second, lower intensity through a single layer of the fabric of the workpiece, and at a third, very low or no intensity through the seam, to provide a contrast in light intensities that highlight the shape of the workpiece and the location of the seam, which appears as a dark or black line. A CCD Vision System Camera (22) can be mounted above the lighted surface to capture an image of the workpiece which is transmittted to a controller. The controller compares the image of the workpiece to a stored image of a like workpiece of known orientation to determine the actual orientation of the workpiece. The computer (26) can then, if desired, use an industrial robot or other similar device (30) to reorient the workpiece to a desired orientation for further processing.

Title: Power supply for electrostatic precipitator electrodes
Inventor: JOHNSON NATHANIEL M
IPC: H02M7/10
Filed: 1996-03-19
Abstract: A power supply system particularly adapted for use with an electrostatic precipitator to provide substantially ripple-free DC power for improved precipitator operation. The power supply is adapted to receive three-phase AC  power and to transform the AC power into high voltage DC power having a minimum of voltage ripple in the output. The power supply includes a multi-phase transformer having three primary windings, each of the primary windings having associated with it a pair of secondary windings. The primary windings can be either delta connected or wye connected. One of each of the secondary windings associated with one of the respective primary windings is connected together in a delta connection arrangement, and the remaining secondary windings are connected in a wye connection arrangement. Because the respective AC voltage outputs of each of the secondary windings are out of phase with the AC voltage outputs of the other secondary windings, the resultant combined DC  output voltage, after the DC voltages have been rectified in a three-phase, full-wave bridge rectifier stack, which produces minimal ripple voltage and current, without requiring additional, more expensive, and less reliable components.

Title: A method and apparatus for removing gaseous elementary mercury from a gas
Inventor: ALLGULIN TORKEL
IPC: B01D53/78
Filed: 1998-05-22
Abstract: A method for removing gaseous elementary mercury from a gas that can be permitted to contain sulphur dioxide. The gas is treated in a washing tower with washing liquid that circulates in a closed system and that contains 0.01-300 mmol/l mercury (II) ions and at least twice this amount of chloride ions. The elementary mercury present in the gas is oxidised and solid mercury (I) chloride is formed. A part of said formed solid mercury (I) chloride is passed to a reaction unit for oxidation to mercury (II) chloride. Chlorine intended for said oxidation and liquid intended for taking-up mercury (II) ions formed by said oxidation process is caused to pass up through a reaction zone in the bottom part of the reaction unit and said zone is kept substantially full of solid mercury (I) chloride. The quantity of chlorine is adapted so that said chlorine will be essentially consumed during its passage up through the reaction zone. The liquid and its content of formed mercury (II) ions is united and mixed with the washing liquid present above said reaction zone and thereafter the so united washing liquid is passed with its increased mercury (II) content to the closed circulating system to be recycled to said washing tower as a compensation for the mercury (II) ions consumed for the oxidation of elementary mercury.      An apparatus for effecting the method has a washing tower (11) and a reaction unit (26) with a smaller cross section than the tower (11). The reaction unit (26) is connected to the bottom of the tower (11) and has conduits and means for maintaining a closed circuit system of washing liquid from a liquid outlet (41) in the lower part of the tower (11) to a liquid inlet (40) in the upper part of the tower (11). The lower part (42) of the washing tower (11) below the level of the liquid outlet (41) has a tapering cross section for adaptation to the reaction unit (26).

Title: Proxy database for element management system of telephone switching network
Inventor: HSIEH JIAN J
IPC: H04M3/22
Filed: 1999-08-09
Abstract: An element management system ("EMS") interfaces between a telephone company computer or a terminal for use by a telephone company system administrator or customer service representative, and a telephone network element such as a central office or a group of central offices. In order to store and process subscriber data during the time periods when a telephone computer system is busy controlling telephone switching functions and therefore giving low priority to such data, the EMS contains a proxy database and maintains it between the periods when access to the telephone computer system is desired and available, without detrimentally involving the telephone computer system, the telephone switching network or any elements thereof. The EMS is capable of operating as the sole repository of subscriber data in a telephone computer system configured to operate in such an environment. The proxy database effectively mirrors subscriber data in one or more central offices and/or other network elements of the telephone computer system. By utilizing the proxy database, the EMS (i) provides relatively current subscriber data to telephone company personnel and systems, and (ii) accepts telephone network configuration commands from such personnel and systems, communicates the commands to the corresponding network elements, and upon receiving information indicating that the commands have been carried out, provides verification information to the client personnel and systems.

IPC: D04H1/46
Filed: 1998-03-20
Abstract: A dual-zoned, three-dimensional, resilient absorbent web is disclosed which is suitable as body-side liner for absorbent articles such as feminine pads, diapers and the like. When used as a liner in absorbent articles, the dualzoned web combines the advantages of apertured films and soft, nonwoven cover layers in one structure while still being inherently hydrophilic. The liner comprises a web of wet-resilient, hydrophilic basesheet having a threedimensional topography comprising elevated regions onto which hydrophobic matter is deposited or printed and a plurality of spaced apart depressed regions. In a preferred embodiment, the hydrophobic matter applied to the elevated regions of the basesheet comprises hydrophobic fibers in a contiguous nonwoven web which has been apertured or provided with slits or other openings, such that the apertures or openings overlay a portion of the depressed regions. The elevated hydrophobic regions enhance dry feel and promote fluid flow toward the lower hydrophilic regions, which comprise the exposed depressed regions of the basesheet. The basesheet is preferably in liquid communication with underlying absorbent material, most preferably a stabilized airlaid cellulosic material or compressed stabilized fluff such that the absorbent material can wick fluid out of the basesheet by capillary action. When soft, hydrophobic fibers are deposited on the elevated regions, the liner also has a soft, cloth-like feel in addition to a dry feel in use.
