Title: Edge detection; automatic sewing
Inventor: SADEH YAACOV
IPC: D05C5/06
Filed: 1990-08-30
Abstract: In an automatic sowing machine, a cloth component 12 is placed on a movable table 10 and viewed by CCD camera 20 as camera 20 or component 12 is moved. Image analysis allows the edge of component 12 to be located and compared with its correct position. Component 12 is then moved so that the edge is in the correct position for sewing. Location is aided by selectively illuminating lights 26 or by staining the edge, e.g. with fluorescent dye, either when the component is cut (fig 6) or subsequently (fig 8). Alternatively contrasting powder may be deposited on the component (fig 9) or parallel stripes of light can be projected onto the edge (fig 10). More than one light source and camera are possible (fig 11) and the stripes of light may be replaced by a scanned light spot (fig 12). <IMAGE>

Title: Recovery of heavy metals from water
Inventor: BRISTOWE JOHN DOUGLAS
IPC: B01J39/02
Filed: 1992-02-18
Abstract: The process is an almost self sustaining method of recycling heavy metals, which at present are not recovered during water treatment. It uses the most effective of the various inorganic cationic exchange materials, with good selectivity for absorption of the polluting or valuable metal cations, it is intended to recover. These may be present in effluent, or natural waters, including the sea, which contain much larger concentrations of common ions. The process can recover from low concentrations of valuable metals, and reduce harmful metals to the lowest required levels. The metal cations are deabsorbed into the acid used to regenerate the exchange material, which can be used repeatedly. The metals are recovered from the acid when it is used as an electrolyte, and they are separated by electrodeposition at the cathode. The cationic exchange material may be zirconium phosphate; ammonium molybdophosphate; ammonium tungstophosphate; or a material produced from potassium ferrocyanide and either sodium molybdate or sodium tungstate.

Title: High power light source
Inventor: RAVEN ANTHONY
IPC: G02B27/00
Filed: 1993-01-07
Abstract: An optical system for producing a high power light source comprises a number of laser diodes, or similar sources, which emit light from an emission stripe (8) having a long dimension a (x-axis) and a short dimension b (y-axis) and which have a higher numerical aperture in the y-axis than in the x-axis. The laser beams (9) are collimated by a lens (10) and focused onto an optical fibre by a further lens (20). Prior to the focusing, the collimating beams (11) are anamorphically expanded/reduced by beam shaping means (12) so that the width of each beam (11) in the x-axis is increased to the width in the y-axis. The images (21) produced on the fibre end are thus anamorphically magnified so that the anamorphic ratio between the magnification of the stripe (8) in the y-axis and in the x-axis is greater than one. By the brightness theorem, this anamorphic magnification results in a correspondingly relative decrease in the y-axis numerical aperture to enable a corresponding increase in the number of beams (11), which can fit into the solid angle of the target. <IMAGE>

Title: Method of manufacturing current collectors for electrochemical cells by electroplating wire with indium and drawing
Inventor: MIHARA DAVID ROBERT
IPC: H01M4/82
Filed: 1993-06-02
Abstract: Current collectors having particular utility in alkaline electrochemical cells, particularly zinc/manganese dioxide alkaline cells containing "zero-added" mercury are manufactured by a process involving electroplating conductive wire with indium and then drawing the plated wire to a lesser diameter. The drawn plated wire may then be cold-framed and cut to the desired lengths, typically in the shape of a nail. The drawing increases uniformity of the plating and hence smoothness and lustre, and also increases plating adhesion. Reduction in cell gassing and load voltage instability during cell discharge is thereby achieved.
