A machine for and method of manufacturing concrete U-wall type construction blocks by molding each concrete u-wall construction block from concrete poured about a block cage made from reinforcing material while said block cage is loaded within the machine. The method involves providing a system of molding jacket panels, including a core molding assembly having a pair of inside stem jacket panels that are adjustably supportable in a substantially parallel manner during a molding process, and arranged is such a manner that the front wall portion is molded in downwardly facing direction toward a horizontal support surface and completely enclosed in one or more molding jacket panels. Before block molding operations, the thickness of the front wall portion of the U-wall construction block is set by determining the thickness of a front wall surface liner and installing the front wall surface forming liner within the system of molding jacket panels.

The present invention provides a method of forming a frame core (1) having a center leg (3) for an inductive component, and an accordingly formed frame core (1) having a center leg (3) and an air gap (4) in the center leg (3). The frame core (1) is formed integrally with the center leg (3), the air gap (4) being molded into the center leg (3) during the formation of the frame core (1).

Resin-based structures for use in corrosive environments. The resin-based structures may include a mixture of resin and aggregate. The resin-based structures may be formed in a mold by placing aggregate and resin into the mold. The resin-based structures may have thin wall design with high compression and tension strength.

Disclosed herein is a compact (e.g., one-piece) refractory cast iron combustion chamber mold for a circulating fluidized bed boiler for the combustion and/or gasification of biomass, waste, lignite and mixtures thereof, and a method of obtaining a combustion chamber with this mold.

A preform tooling arrangement includes a base plate comprising a male die surface and a stripper plate comprising a female die surface. A plurality of perforations are disposed in the base plate and/or the stripper plate. The stripper plate is moveable with respect to the base plate. The preform tooling arrangement is configured to receive a fibrous preform between the male die surface and the female die surface. The preform tooling arrangement is a dual-purpose fixture configured to accommodate z-needling and densification, all while the fibrous preform remains in the same fixture (i.e., the preform tooling arrangement). The perforations are configured to receive one or more textile needles for through thickness reinforcement of the fibrous preform.
