Abstract: A method of superplastically forming an article from a light metal base alloy, of the kind capable of having its crystal structure modified by cold working in such a way that subsequent dynamic recrystallization by hot working is facilitated, comprises cold working a first blank of the alloy to form a second blank having the modified crystal structure, and then forming the second blank into the article by hot working so that dynamic recrystallization is induced and super plastic deformation occurs. The degree of modification of the crystal structure during cold working is such that as the dynamic recrystallization continues, the grain size is progressively refined.

The apparatus for carrying out the method includes at least one compressed-air nozzle which is adapted to be recurrently directed towards and brought to sweep over said cooling-coil batteries in order to blow away the frost deposit.

Abstract: A device which, when manually operated, will automatically return to an original position wherein a manually-operated control lever rotates at least one shaft having an arm mounted on the end of the shaft, and with a roll at the other end of the arm which abuts against one of two profiled parts when the shaft is rotated by the control lever. The two profiled parts resiliently abut a stop or stops when the arm is in an original or zero position but one profiled part abuts a stop while the other profiled part resiliently abuts the roll on the end of the arm when the shaft is rotated, and the profiled parts have steps thereon which are position markings able to be sensed manually by the control lever by a snap effect.

Abstract: The scuff resistance of high-pressure laminated plastic is improved by incorporating in or very near the surface thereof, finely divided polyethylene wax having a particle size of about 1-25 microns and a melting point of preferably 220.degree.-230.degree. F. The wax is incorporated as part of an abrasion-resistant coating mixture applied to the face of an unimpregnated decor paper sheet in an ultra-thin layer, which layer is dried at a temperature below the wax melting point and then impregnated with conventional melamine-formaldehyde resin. The impregnated sheet is placed onto a sheet of convention phenolic resin impregnated core sheets and consolidated in the conventional way under heat and pressure. During consolidation, the wax particles "bloom", or migrate to the surface. The finished laminate surface has greatly improved scuff resistance.

Abstract: A dispenser for containing and dispensing a premoistened web of material (26) comprises a magazine (2) for containing the web of material and a dispensing portion (3) associated with the magazine and having an opening (20) for dispensing the web of material.
