Abstract: An improved combination carrier and stop assembly is provided for use in automated conveyor assembly systems.  The carrier includes a reject pin having two positions that flags defective workpieces and further confirms that non-defective workpieces have passed the previous quality checks.  The carrier also includes an improved mechanism for being grasped and lifted by the stop assembly unit of the present invention thereby enabling the stop assembly unit to grasp and lift the carrier and workpiece above the forwardly moving conveyor.  The stop assembly detects the presence of a carrier, automatically checks the defective/non-defective status of the workpiece and thereafter grasps and lifts the carrier and workpiece above the conveyor if a task is to be performed.  The stop assembly also includes an air-assisted release mechanism to facilitate the release of the carrier from the stop assembly after the task is performed.  A programmable controller controls the moving parts of the stop assembly.

Title: Method of making pig iron with zinc recovery
Inventor: BERNARD JOHANNES GELEIJN
IPC: C22B19/14
Filed: 1995-06-07
Granted: 1999-05-25
Abstract: A method making pig iron employs an in-bath direct reduction performed in a metallurgical vessel which has above it a melting cyclone in which  iron-oxide-containing material fed thereinto is pre-reduced by hot reducing gas coming from the vessel.  Molten material passes downwardly from the melting cyclone into the vessel.  In order to recover zinc from a dust containing zinc and/or zinc oxide, the dust is fed into the melting cyclone.  Zinc is allowed to vaporize out of the dust into the hot gas in the melting cyclone.  The hot gas containing zinc is discharged from the melting cyclone, and zinc-containing material is extracted from this hot gas.

Abstract: The present invention refers to a method of producing a tubular lining hose, in particular for use in sewer reconstruction work, comprising the steps of forming at least one fibrous strip into a curable, resin-impreganted hose. The inner side of the resultant lining hose is provided with a protective foil. It is the object of the present invention to provide a method of producing a tubular lining hose with the aid of which hoses of arbitrary length can be produced in a simple manner. This object is achieved by producing first a foil hose, which forms the protective foil, by helically winding a foil strip onto a winding mandrel, the fibrous strip being then wound onto said foil hose. In addition, the present invention refers to apparatuses for carrying out said method as well as to the lining hose itself.

Title: A configuration method for a data management system
Inventor: WILBY MARK
IPC: H04Q3/00
Filed: 1995-08-09
Granted: 2000-10-03
Abstract: Data elements stored in a distributed data structure are accessible by means of a hierarchical routing network in which routes through the network to individual data elements are flagged. The network comprises communicating links between nodes (1, 2, 3), extending from a "root node" (2) to a plurality of end nodes (3). The end nodes (3) contain the data elements. To find a data element, a search message entering the network at an end node (3) passes through the network towards the root node (2) until it encounters a flagged route to the relevant data element. Thereafter it passes along the route to the end node (3) containing the relevant data element. The invention is relevant to personal numbering services in a communications network. In this case, the data elements each comprise hardware addresses for users of the network. If a user moves in relation to the network, their hardware address will change and, in many cases, the relevant end node (3) will also change. However, the flagged route consequently changes and the routing network therefore provides automatic tracking of the user.

Title: Magnification correction for small field scanning
Inventor: ALLEN PAUL C
IPC: G03F7/20
Filed: 1996-03-19
Granted: 2001-07-03
Abstract: Magnification correction for small field scanning of large blanks is provide d by adding magnification adjusting elements (lenses 712, 714, 722, 724) to a double pass Wynne-Dyson lens (770) or other type of one-to-one projection lens. The magnification adjusting optical elements include two pairs (710, 720) of low power lenses, one associated with each of the input and output prisms (731, 732) of a Wynne-Dyson lens. Movement of the magnification adjusting optics provides positive or negative magnification as needed to correct for any expansion or compaction of the blank (160) relative to the reticle (120) and hence maintain alignment. Further magnification correction  is provided by a small velocity relative movement between reticle (120) and blank (160) by means of a secondary stage in the scan direction. This correc ts for any alignment error in the scan direction and may be used independently of the optical correction technique with any type of projection lens.

Abstract: A method for producing flexible, low-bulk towpreg which involves powder coating a bundle of unspread fiber tows (35) arranged in a predetermined cross-sectional shape, and the resulting towpreg. During the powder coating process, the resin powder particles do not enter into the fiber bundle, but rather only coat the surface fibers comprising the tows, resulting in dry fibers in the core of the towpreg and outer fibers which are coated with a discontinuous sheath of resin on the surface of the towpreg surrounding the core of dry fibers. The resin layer on the surface of the towpreg is formed by a partial melting of the powder particles. A post-treatment process can be used to convert flat ribbon towpreg produced in accordance with the present invention into fexible unidirectional tape.
