Title: Process for regenerating sodium sulphide from the sodium sulphate which forms in treating lead past from exhausted batteries
Inventor: OLPER MARCO
IPC: C01B17/22
Filed: 1997-11-27
Abstract: A hydrometallurgical process is described for regenerating sodium sulphate used for sulphuration of Pb paste from exhausted batteries, with a view to electrochemical recovery of the lead.          The elemental sulphur reacts rapidly with an aqueous lime suspension (heated to between 90 and 100°C) in accordance with the reaction 3Ca(OH)2 + 4S°  -->  2CaS + CaS2O3 + 3H2O                  (1) CaS and CaS2O3 remain in the solution, which is added hot to a concentrated solution of sodium sulphate, to effect the double exchange reaction: 2CaS + CaS2O3 + 3Na2SO4  -->  2Na2S + Na2S2O3 + 3CaSO4       (2) The calcium sulphate precipitates in easily separable crystalline form and leaves the cycle.          The filtered sodium sulphide and thiosulphate solution is advantageously used for converting the various paste components into PbS.  In this respect, the products of the reaction between the solution and the paste components (PbSO4, PbO, PbO2) are PbS and SO4 2-, so that after separating the PbS by filtration the sodium sulphate solution can be concentrated and recycled to reaction 2).

Inventor: KEAR BERNARD H
IPC: C01G45/00
Filed: 1997-11-18
Abstract: A chemical synthetic route for nanostructured materials that is scalable to large volume production, comprising spray atomization of a reactant solution into a precursor solution to form a nanostructured oxide or hydroxide precipitate. The precipitate is then heat-treated followed by sonication, or sonicated followed by heat treatment. This route yields nanostructured doped and undoped nickel hydroxide, manganese dioxide, and ytrria-stabilized zirconia. Unusual morphological superstructures may be obtained, including well-defined cylinders or nanorods, as well as a novel structure in nickel hydroxide and manganese dioxide, comprising assemblies of nanostructured fibers, assemblies of nanostructured fibers and agglomerates of nanostructured particles, and assemblies of nanostructured fibers and nanostructured particles. These novel structures have high percolation rates and high densities of active sites, rendering them particularly suitable for catalytic applications.

IPC: A61F13/02
Filed: 1997-02-07
Abstract: A tab member (25), especially for use as a "non-touch" grip for applying a dressing (21) comprising an adhesive layer (23) and optionally a release liner (24) to the skin without touching the adhesive layer (23). The tab member (25) comprises at least a first flap member (26) and a second flap member (27) being joined along one edge thereof so as to form a tab having a V-formed cross section substantially perpendicular to the line of conjunction. The combined thickness of the two flap members (26, 27) in the area of conjunction (28) is smaller than the thickness of a bended edge of the two flap members (26, 27). This is a particular advantage while a decrease of the thickness of the area of conjunciton (28) results in a decrease of the area of the adhesive (23) in front of the area of bending or conjunction (28), which may be subjected to air.

Title: Method and system for characterizing terminations in a local area network
Inventor: RICHARDSON WILLIAM M
IPC: G01R31/11
Filed: 1997-07-09
Abstract: The location of a termination in a properly terminated LAN can be remotely detected. The cable's skin effect produces a detectable signature at the sending-end when a step function, for example, reaches the termination.  Accordingly, a network analysis device is connected to the network to inject the step function onto the network cabling. The voltage response of the cabling to this is first digitally sampled and then analyzed in a system controller. The system controller reviews the sampled data for an inflection point and then locates the termination by reference to the delay between when the signal was placed on the cable and the detection of the inflection point.
