Title: Process for the recovery of noble metals and tertiary phosphines
Inventor: DE OLIVEIRA BANDARRA JOAO JOSE
IPC: B01J31/24
Filed: 1992-12-29
Granted: 1999-09-07
Abstract: The present invention concerns a process for the recovery of a noble metal from an inorganic and/or organic residue in the form of a tellurium amalgam characterised by adding a solvent having a boiling point above 120°C to the residue, removing by distillation water  and other residual solvents having boiling points below the boiling point of the added solvent, adding the tellurium or reducible tellurium compound, and then refluxing at atmospheric pressure before separating the amalgam of the noble metal.       The process of the present invention also allows the simultaneous recovery of the tertiary phosphine as its oxide from a residue containing a tertiary phosphine by the further stages of concentrating the mother-liquors remaining after separation of the amalgam of the noble metal, recovering the added high boiling point solvent and isolating the tertiary phosphine in the form of its oxide by precipitation with water.

Abstract: A radio transceiver having an integrated transmitter and receiver for transmitting and receiving microwaves or higher frequency electromagnetic waves is one of a series of device products corresponding to different transmission output power capacities. In this invented series of device products, a radio transceiver which is of a minimum size to meet its transmission output power requirement without an amplifier is composed of entirely standardized basic components, a transmission module, a reception module, and a transmission and reception shared circuit which are housed in a heat radiating housing case irrespective of different transmission output power requirements. Corresponding to the transmission output pawer requirement, a power amplifier is added to the basic components. The heat radiating housing case which houses the basic components and the power amplifier is longer than, but has the same cross section as, the heat radiating housing case which houses no power amplifier, thereby radiating the heat produced by the power amplifier. The heat radiating housing case is thus substantially standardized.

Title: Analyzing an image showing a graphical representation of a layout
Inventor: MAHONEY JAMES V
IPC: G06V30/40
Filed: 1994-10-03
Granted: 2001-12-25
Abstract: Input image data define an input image set that shows a graphical representation of a layout with two or more segments. The graphical representation can be a sketch, and can include, for example, a rectangular boundary with lines parallel to its sides defining rectangular segments within the boundary. The input image data are used to obtain segment source data indicating a source for each segment and segment position data indicating a position for each segment. The segment source data can indicate, for each segment of the layout, one of a number of source images in the input image set. The segment position data can indicate a reference point and a width and height for each segment. The source image for a segment can be a sketch of a graphical representation-such as a node-link structure, a parallel length graph, a proportioned parts graph, a row/column representation, a perimeter relationship representation, or a two-dimensional graph-that can be categorized and rendered to obtain data defining a precisely formed graphical representation. The segment source data for other segments and the segment position data can be used with the data defining the precisely formed graphical representation to obtain output image data defining an output image that includes a layout as represented by the graphical representation.

Granted: 1999-05-04
Abstract: The invention provides a route state filter (74) for a vehicle route guidance system for improved tracking of vehicle position with respect to a preselected route. A set of position possibilities are derived by comparing a measured vehicle position (28) to a data-base (30) containing data representing a map of roads, the possibilities corresponding to possible positions on the roads within an error region around the measured position. A route guidance module receives the position possibilities (70), checks their validity (72) and applies a filter to remove less likely possibilities (74). A current position is then selected from the remaining possibilities (76). An ON/ OFF ROUTE status Or the vehicle is determined by comparing the selected position with the selected route information in the database (35, 78). A distance-based filter is utilized to provide improved continuity in the route status determination. The route status is then used to set the system operating mode, and warnings are communicated to the driver (32, 86).

Abstract: A support cylinder for guiding freshly processed substrate  material  between  printing  units  or  at  the delivery end of a printing press is provided with a low coefficient of friction, semi-conductive base covering for supporting and guiding the freshly processed substrate material without smearing the ink or causing indentations on the surface of the substrate.   Radially projecting surface portions  of the semi-conductive base covering define electrostatic precipitation points and reduce the surface area available for frictional engagement.  The low friction  and  semi-conductive  properties  of  the  base covering permit free movement of the freshly processed substrate  relative  to  the  support  cylinder  surface.          Electrostatic charges carried by the freshly processed substrate are discharged through the semi-conductive base covering  into  the  support  cylinder,  thus  eliminating electrostatic cling attraction between the freshly pro-cessed substrate and the support cylinder.

Abstract: An outer layer forming material is injected into a cavity in a mold and then, a core forming material is injected, whereby the core forming material is allowed to flow into the outer layer forming material existing in the cavity, and both the materials are allowed to flow within the cavity.  The cavity has a main area for forming a bumper main portion, and side areas for forming bumper sides.  A relation, d1> d2 is established between a distance d1 determining a bumper thickness of a first section for forming an upper portion of the bumper main portion and a distance d2 determining a bumper thickness of a second section for forming a lower portion of the bumper main portion.  A relation, d3>d1 is established between a distance d3 determining a bumper thickness of the side areas and the distance d1.  A film gate opens into the first section.  Thus, in the main area and the side areas, the times required for the filling of the outer layer forming material to be completed are substantially equal to each other.
