Abstract: An inlet screen for an ocean thermal power plant has an outer side parallel to the ocean current and a plurality of parallel bars extending at an acute angle to the horizontal, wherein the acute angle opens toward the upstream direction of the current. The total area of through openings in the inlet screen receive the predetermined flow requirement of the power plant at a velocity no greater than 0.5 feet per second, so that fish are not sucked against the screen. The vertical spacing between the bars is no greater than one-half of the inner diameter of tubes in heat exchangers in the plant. The spacing between bars is at a minimum at the outer side of the screen, and the spacing increases between the outer side and the inner side, so that objects do not become wedged between the bars. The inlet screen extends sufficiently below the ocean level to accommodate the plant's water flow requirement at a velocity of no greater than 0.

Abstract: Loosely stacked fuel (6) is introduced through a charging opening (5) into the furnace (1) of the boiler on a first support (7), and jets (25) of ignition air entraining hot flue gas from the furnace are directed at the surface of the fuel on the support so that the surface layer is ignited and the fuel is partially gasified. The fuel is passed onto a grate (9) located at a lower level on for final combustion. The air from the ignition air jets (25) are permitted, together with the entrained flue gas, to pass down through the loosely stacked fuel (6) and the first support (7) and then to flow off to the furnace (1). The flue gas entrained by the ignition air jets (25) is drawn substantially from a section of the furnace through which flows a mixture of combustion products from the first support and the grate.

Abstract: An interlocking block for constructing walls without mortar at bed joints includes an inner wall, an outer wall, and a web arrangement connecting the walls, wherein upper and lower surfaces of the block when in use are formed in contact with walls of a mold, and the block is slipped from the mold in a direction parallel to the mold walls. Interlocking recesses and ridges are formed in one piece with the walls of the block. The web is minimal in cross-sectional area and is positioned at one end of the block and between the top and bottom to create large empty volumes defining vertical and horizontal passages. The block can include one or more intermediate walls parallel to the inner and outer walls and additional webs to connect the intermediate walls to the inner and outer walls.

Abstract: A model toy train track assembly provides separate electrical and mechanical locking or snap-together connections. A molded base of each track assembly has a protruding U-shaped feature on each end that physically joins to track assemblies or sections when pressed into a complementary receiving slot. To provide a reliable electrical connection, metal connectors corresponding to each of the rails lock into receiving connector slots of the adjoining track section. Alignment ribs on opposite sides of each rail ensure straight and accurate alignment of the rails. To prevent slipping of the rails, each rail is staked into the molded base. The rails are tubular and sized and positioned so as to provide compatibility with conventional two-rail or three-rail tubular tracks of similar gauge.
