Abstract: The invention comprises an item of footwear, comprising: a) an upper sole, shaped to receive a user's foot, and including a toe cap portion, a heel portion, and a sole portion, which is formed from a lightweight, thermally insulative plastics material; b) a lower sole, formed from a resilient plastics material, the lower sole attached to and at least partially covering the sole portion of the upper sole and operative to protect the upper sole from direct physical contact with the ground and to minimize wear on the upper sole; and c) an upper attached to the upper sole.

Abstract: An article of footwear having a rubber outsole, a polyurethane midsole bonded to the rubber outsole by polyurethane (PU) adhesive, and a polyurethane upper bonded to the midsole and the rubber outsole by injection molding. The invention also relates to a method of manufacturing an article of footwear comprising the steps of applying a layer of primer to a selected portion of a rubber outsole and allowing the layer of primer to dry; applying a first layer of PU adhesive over the primed portion of the outsole and allowing said first layer of PU adhesive to dry; applying a second layer of PU adhesive over the dried first layer of PU adhesive and allowing the second layer of PU adhesive to dry; forming, separately, a polyurethane upper by injection molding; setting the outsole and the upper in a mold; and, forming, via injection molding, a polyurethane midsole and activating the PU adhesive to bond the outsole to the midsole and to the upper, thereby forming the article of footwear.

Abstract: In accordance with the present invention there is disclosed safety footwear comprising a unitarily moulded lower member having a sole portion and a toe cap portion. One or more protective elements are embedded in the unitarily moulded lower member so as to prevent breaches thereof.

Abstract: Amongst other things, a boot is provided having a foot portion for enclosing the foot of a user and a leg portion having a substantially circular cross-section and extending upwardly from the foot portion. A first strap portion is affixed to one or the foot portion and the leg portion, and extends more than 180° around the perimeter of the leg portion in a first circumferential direction. A second strap portion is affixed to one of the foot portion and the leg portion, and extends around the perimeter of the leg portion in a second circumferential direction substantially opposite to the first circumferential direction, to meet the first strap portion. A fastening means is provided for releasably joining the first and second strap portions in circumferentially adjustable relation, to cinch the strap portions around the perimeter of the leg portion in conjoined relation.

Abstract: An elixir for treating wastewater by transforming metals into metal sulfates and sulfides, breaking up chelated metals, and precluding the metal sulfates and sulfides from redissolving back into the wastewater. The elixir comprises: 1) ferrous sulfate heptahydrate, 2) aluminum sulfate, 3) 75% sulfuric acid, 4) a blend of aluminum salts and a polymeric coagulant, and 5) water.

Abstract: A process for removing metals from wastewater, which comprises the following: measuring the flow rate and oxidation reduction potential of wastewater as it is fed into a first treatment tank, adjusting the pH of the wastewater, adding a first liquid elixir to the wastewater to react with at least one metal in the wastewater to cause it to either precipitate out of solution, or convert into a form that will allow it to be precipitated out of solution by a second liquid elixir, and to bond with the metal to prevent it from re-dissolving back into solution, adding a second liquid elixir to the wastewater to react with at least one metal in the wastewater to cause it to precipitate out of solution, and to bond with the metal to prevent it from re-dissolving back into solution, feeding the wastewater into a second treatment tank, mixing a third liquid elixir and a fourth liquid elixir into the wastewater to flocculate and/or coagulate the precipitated metals, and separating the flocculated and/or coagulated precip

Abstract: An elixir for treating wastewater by transforming metal sulfates into metal hydroxides, breaking up chelated metals and transforming the freed metal ions into metal hydroxides, and precluding the metal hydroxides from dissolving back into solution. The elixir comprises: 1) calcium hydroxide, 2) METEX EPS, 3) sodium dimethyl dithiocarbamate, 4) calcium hypochlorite, 5) sodium hydroxide, 6) a combination of calcium salts and a first polymeric coagulant, 7) a second polymeric coagulant, and 8) water.

Abstract: An elixir to aid in the coagulation and flocculation of metal precipitates in wastewater, and to aid in their settling out of the wastewater solution, comprising: 1) a first cationic polyelectrolyte, 2) a solution comprising a second cationic polyelectrolyte, an acrylamide, and a cationic monomer, 3) a polymer with a high molecular weight and a high charge density, and 4) water.

Abstract: An elixir to aid in the coagulation and flocculation of metal precipitates in wastewater, and to aid in their settling out of the wastewater solution, comprising: 1) a first anionic polymer with a high molecular weight and a high charge density, 2) a second anionic polymer with a high molecular weight, 3) a liquid emulsion anionic flocculant with a high molecular weight and a high charge density, and 4) water.
