A control wheel intended for welding onto the high-pressure rotor of a steam turbine is manufactured from a ring of individual blades welded together. For this purpose, all of the individual blades are provided with shrouds and root platforms having welding grooves formed therein. After being welded together into a ring, closed on all sides, the control wheel is annealed, machined and finally heat...

The appts. has a flexible nozzle support, which slides within a nozzle box and nozzles extending towards a major surface of the glass sheet to form a quench surface which can be adjustably flexed to match the transverse curvature of the sheet. The process comprises shaping the sheet at its softening temp., (partially) tempering the sheet by directing coolant at its opposing major surfaces from a q...

The anode in the cell is in contact with hydrogen contained in a container inside another container to which it is connected, and which contains hydrogen at a higher pressure, using a connection formed as a redn. valve. This maintains hydrogen pressure in the first container at a constant level. The redn. valve is fitted on an intermediary wall between the two containers. - The electrolytic layer ...

A hygroscopic commodity, such as a continuous stream of shredded tobacco, is transported past one or more sources of electrical energy and past one or more monitoring devices. One of the sources can expose the stream to the electric field of a capacitor in a high frequency oscillator circuit, and the other source can expose the stream to infrared waves or microwaves. The moisture in the stream inf...
