Title: Modular reinforced concrete wall panels - double skin outer surface insulation gap carrying services, and inner surface
IPC: E04C1/39
Filed: 1974-06-13
Abstract: Walls and partitions are made from modular reinforced concrete components which are quick and easy to assemble without the need for skilled labour. The use of shuttering is also eliminated. Each module is approx. (0.5m) high and in standard lengths of up to (2, 50m) thus remaining light enough to transport easily. It has two sections (1, 2) separated by a layer of air (3) and joined by plates (4) made of a damp-proof material. An inside partition panel (10) insulated from the main module by a layer of air rests on supports integral to the inside wall of the module. These supports also carry gas, electricity and water pipes. The space between the wall and the partition can be of any standard width. The modules are assembled by means of rebates (20, 21, 22) which allow the blocks to be accurately positioned one on top of another.

Title: Profile bar extrusion press for reverse operation - has die holder and shaver punch on indexing plate
IPC: B21C23/21
Filed: 1975-03-27
Abstract: An extrusion press for profile bars has an axially stationary die plate holder and a die plate ring. A pressure plate assembly with a coaxial loader ring is moved along the extrusion axis by hydraulic cylinders. This forces the extrusion blank in the loader ring against the die ring so that extrusion takes place. When the extrusion is completed, radial cutters remove the remainder of the blank so that the loader ring can be retracted. A shaver punch is then swiveled into the position of the die punch so that it can clear the remaining blank skin inside the loader ring. A loading cross slide places in the mean time a new blank in a coaxial position with the loader ring.

Title: Continuous high gloss transfer printing - uses rapidly drying varnish and printed motifs
IPC: B41M7/00
Filed: 1977-01-28
Abstract: The transfer support receives a layer of film-forming varnish on its lower side as it passes through the rollers. Transfer print motifs are applied on to the varnish layer by the printing rollers. The transfer of the layer of varnish and the prints is effected on to the support by the pressure rollers.
