Title: Hot pressing of ceramic materials
Inventor: MOORE DONALD AVON
IPC: B28B3/02
Filed: 1986-08-19
Abstract: In a method using a column of interfitting die assemblies, pressure is applied to the heated assemblies in such a way as to cause movement of opposite ends of the material in each die assembly relative to the die assembly. Also disclosed is a method in which partly compacted material is located in a die assembly, comprising moving opposite ends of the material relative to the die assembly. Ceramic material is introduced in bores (37) in a die (36) provided with slidable plugs (39, 40). The die is loaded into a carrier (30) along with similar units to form a column of die assemblies in which each carrier bears on the die in the next carrier. The slugs of ceramic material are subjected to a double-ended pressing operation. The die may be temporarily maintained in the position shown in which it is clear of the base of the associated carrier either by partly compacting the material so that it frictionally engages the die or by means of a frangible spigot (see Fig.4). <IMAGE>

Patent GB-2230029-A (GB)
Title: Push-fit cladding system
Inventor: NORDERHAUG ARNE
IPC: E04B2/74
Filed: 1989-04-07
Abstract: Cladding panels 1 are provided with flexible fixing flaps 2 which correspond to slots 4 in the support rails 3 so that the panels may be fitted by merely pushing them onto the support rails; the flaps flexing out and clipping into the slots. The panels may be further secured by inserts into the joints between the panels preventing the flaps from slipping out of their slots. There would normally be only one fixing flap on each of two opposite panel sides, thus thermal expansion problems are avoided. As support rails are required only along the joints with fixing flaps, they are needed in one direction only; thus when vertical, they could span from floor to floor. The support rails may be formed to act as drainage for any water penetrating into the joints, thus reducing reliance on the joints' sealing gaskets.
