A wave energy converter (WEC) includes a float and a spar for guiding the up and down movement of the float in response to the waves. A power take off (PTO) device coupled between the float and the spar and mounted within one of the float and spar such that the PTO includes apparatus responsive to the mechanical interaction of the float with the portion of the spar in proximity to the float for converting their relative motion into useful energy. In one embodiment the PTO includes a linear rack extending along an external portion of the spar and a linear to rotary converter, mounted within the float, including a double sided toothed belt for engaging the rack and causing rotation of the rotary converter to drive an electric generator. In another embodiment the PTO includes tires mounted within the float which rotate as the float moves up and down. In another embodiment the PTO includes a rack and pinion arrangement with one of them connected to the spar and the other mounted in the float.

A tidal power generator has a floating vessel hull that is subject to rising and falling water levels so that the hull moves vertically up and down. Linear-to-rotary converters are coupled between the vessel hull and a fixed object. The converters allow the hull to move vertically while constraining the horizontal movement of the hull. The converters convert the vertical movement of the hull into rotary movement, which is then used to drive an electrical generator. A harborage is provided to protect the hull and the converters and to regulate the water level for the vessel hull as well as become a fixed object relative to the vessel from which a change in relative position causes power to be developed. If the hull is subject to tidal variations, vertical movement of the hull can be desynchronized from the tidal variations so as to store energy during slack tides.

The invention relates to a steel-tapping hole with curtain skimming of Linz-Donawitz, which is formed by channels of liquid steel and high pressure draught. The channel of liquid steel is divided into three parts: upper part, middle part and lower part. The upper part is entry channel of round cross-section, the middle part is air cavity channel of ellipse cross-section, and the lower part is outlet channel of round cross-section. The channel of high pressure draught is connected with the air cavity channel of steel-tapping hole. The brachydiagonal direction of ellipse structure of the air cavity channel points to the runner direction of high pressure draught. Diameters of outlet channel become smaller gradually. The favorable result of this invention is as follows: An air cavity of high pressure draught is formed in the steel-tapping hole for skimming, which guarantees liquid steel to drain away extremely and advances the tapping rate of furnaces. Long-range control can be realized with convenient operation and sensitive action.

A rotary converter of wind energy with a vertical axis of rotation includes a rotor with a vertical axis of rotation 4, which has two or more shovels 6 connected to a central body 5 and / or to each other. The shovels called “working” shovels have wind-permeable structure 2. On one side of the shovels is formed a working surface. It is formed on same side of all working shovels by a flag or flags 1 of which the structure limits the capability to take the direction of the air flow, meeting with this side of the shovels. By this surface, the shovels catch the wind energy and convert it to a rotational motion of the rotor. The shovel's load and the rotor speed can be regulated.
