Abstract: There is currently a demand for buildings that can be formed both quickly and economically. These buildings require the addition of heat insulation to walls or roofs because the materials from which they are otherwise formed have insufficient ability to protect against the cold. This can add undesirable expense and slow down production rates. A method is disclosed of forming a building that addresses this problem. The method comprises arranging a door frame, window frame or edge support frame at a mould and spraying a first spray material onto the outside of the mould so that the spray material sets generally in the shape of the mould and substantially embeds the frame. The first material and the frame is removed from the mould and a second different spray material is sprayed onto the first spray material to provide a skin therefor.

Abstract: The invention concerns a building having a wall comprising a plurality of structural wall panels, each panel having: a central core at least 80 mm thick formed from a substantially rigid polyurethane foam; and a polyurea or polyurethane skin 1-6 mm thick substantially encapsulating the central core; at least some of the panels incorporating a roof section; and the panels having sufficient 3 structural integrity to provide at least a wall of the building without the need for support beams.

Abstract: An assembly of mouldings that can be joined together and used as boats or other floating structures. The mouldings are advantageously of rotational moulded plastics material and can be of identical shape. Each of the mouldings has an outer face incorporating at least two zones that are advantageously flat and disposed at an angle one to the other so that one moulding can be joined to another face-to-face in different configurations. In one of such configurations, the first zone of one of the mouldings is in face-to-face relationship with one of the zones of another of the mouldings. In another embodiment the second zone of the one moulding is in face-to-face relationship with one of the zones of the other moulding. The mouldings have outer profiles that are substantially similar. The profiles are advantageously hexagonal. Some mouldings may be joined together end-to-end at end faces that are in face-to-face relationship.

Abstract: Coated display pieces. Display pieces for electronic and mechanical displays are coated with a coating material coating. The coating helps to reduce or prevent breakage or shattering and/or to improve light transmission. Methods of making the coated display pieces are also described.

Abstract: Miniature emblems. The miniature emblems include a shaped miniature substrate having an indicia-bearing upper surface, and a translucent plastic lens cap overlying the indicia-bearing upper surface. A method for making miniature emblems and a cell phone incorporating the miniature emblems are also disclosed.
