Abstract: A multi-ply glove or mitt construction having a multi-ply shell and multi-ply selectively removable liner is provided with interengaging contacting surfaces. The shell is formed by an outer water repellant layer and an inner heat insulating layer, between which is sandwiched a relatively waterproof breathable layer. A slide layer is formed on the inner surface of the inner heat insulating layer. The insulating layer of the shell is preferrably formed of a lofting material such as down, DACRON or THINSULATE fiber, or the like natural or synthetic fibrous materials lending themselves to lofting. The slide layer faces the interior of the glove and is formed of a material providing a shiny surface by means of a non-brushed knit or woven synthetic such as nylon and/or similar sheet synthetic.

Abstract: Laminates of reinforced plastics and copper foil are prepared with a small quantity of benzotriazole in the plastic ingredient. The resulting laminate has excellent bond between the plastic and the copper foil and hence can be employed as an electrical circuit board.

Abstract: The invention is concerned with a carpet cleaning implement useful for continuously washing and rinsing a floor fastened carpet in a single operation. The implement includes a head adapted to be rolled along on a carpet upon wheels. The head includes adjacent its bottom a first row of jets for delivering a flow of a solution of a washing composition such as rug shampoo, under pressure, into the carpet. An oscillatory brush is provided near to the first row of jets for vigorously agitating the solution into the carpet. A second row of jets are located near the brush on its other side. The second row of jets serves to deliver a flow of rinse water under pressure into the carpet.
