Abstract: An ice composite body (10) comprises an inner ice core (11) covered by a protective outer armour layer (12), with means (13) for thermally insulating the ice core (11) therebetween. Refrigeration means comprising a system of conduits (14) for refrigerant are located within the body (10), said insulating means and refrigeration means being adapted, relative to the ambient temperature of the surrounding water (16), to maintain the ice core (11) in a frozen condition. The base (15) of the body can be in direct contact with the water bed (17) such that the ice core (11) is freeze bonded to an advancing ice front (18) in the water bed. The body can be used in warm or cool waters in floating or fixed applications, such as bridges, breakwaters, causeways, pontoons, artificial islands, dams, tidal barrages, wave power barrages, harbour walls, wind power farms or aircraft runways. The ice composite body provides structures of equal or greater strength than equivalent structures using conventional materials, and does so at a significantly lower cost.

Title: Extrusion die
Inventor: CHANG SHU-HUA
IPC: B29C48/92
Filed: 1997-05-13
Abstract: An extrusion die (10) includes a die body (30) having an upstream face (32) and a downstream face (34) with an extrusion profile (22) passing through the body (30) from the upstream face (32) to the downstream face (34). The walls of the extrusion profile (22) being the bearing (46) of the die (10). A pocket (40) having tapered sidewalls (70) is formed in the upstream face (32) of the die (10) and surrounds the extrusion profile (22). The configuration of the pocket (40) improves the material flow through the die (10). The configuration of the pocket (40) depends on the configuration of the extrusion profile (22). The width of the pocket (40) is small at the fast areas of the extrusion profile (22) while being large at the slow areas of the extrusion profile (22). The pocket (40) alters the entry angle of material as it enters the die (10) thus reducing friction in the die (10) and allowing increased extrusion speeds. In conjunction with the pocket (40), the die (10) has a continuous bearing (46) having a length depending on the configuration of the extrusion profile (22).

Title: Manufacture of consolidated composite wood products
Inventor: BARNES DEREK
IPC: B27N1/00
Filed: 1997-07-31
Abstract: Consolidated composite wood products are produced by waferizing wet wood to produce wet green strands and processing the wet green strands by application of adhesive and formation of a lay-up mat for consolidation prior to drying. The lay-up mat is dried in mat form under conditions that maintain the applied adhesive to condition it for the subsequent consolidation step wherein heat and pressure are applied to form a consolidated composite wood product. Preferably, the mat will be formed by orienting the strands to have their longitudinal axes substantially parallel to the longitudinal axis of the product and then the product will be remaned to produce lumber products with the longitudinal axis substantially parallel to the longitudinal axis of the product.
