Abstract: A laser projection system for projecting an image onto a surface comprises a laser projector operably connectable to a computer. The computer controls the operation of the system. The laser projector comprises a laser beam source for generating a laser light beam, a collimator comprising a focusing leans for focusing the laser light beam to a focal point, a collimating lens for collimating the laser light beam beyond the focal point and a wedge-shaped lens having an apertured interposed between the focusing lens and collimating lens. The aperture has a size for passing the laser light beam therethrough. Two scanners direct the light beam about a light path. A photo sensor receives light refracted by the wedge-shaped lens and generates a feedback signal. A plurality of target reflectors, each having a retroreflective material for retroreflecting light back to its source.

Abstract: A process for recovering zinc and iron from zinc- and iron-containing sulphidic material, which also contains lead and silver, in which the sulphidic material is leached under oxidizing conditions in a two stage countercurrent pressure leach to produce a zinc-containing solution from which zinc can be recovered by conventional means such as electrowinning, followed by a reducing leach to produce a lead- and silver-bearing product containing substantially all of the lead and a substantial portion of the silver present in the zinc-containing sulphidic materials, and a high strength iron bearing solution having the iron in the ferrous state from which substantially pure, saleable or environmentally acceptable iron residue in the form of hematite which contains the majority of the soluble iron present in the zinc-containing sulphidic materials is produced.

Opening the first and second moulds. Extending the plug from the boss cavity.

Abstract: A reusable pad for the absorption, dispersion and retention of a liquid comprises an interior layer of hydrophobic material for receiving the liquid, a median layer consisting of a non-woven web of carded and cross-laid viscose rayon fibres and an outer layer of substantially waterproof polyurethane film. The fibres of the median layer have a cross-section of substantially rigid multilimbed configuration. The web is stitchbonded to form a cohesive layer for dispersing and absorbing the liquid. The web is stitchbonded with a thread under medium tension whereby uniform absorption characteristics are retained throughout said web. The interior layer, median layer and outer layer are joined to form a pad of unitary construction and capable of being washed for reuse.
