    摘要: In a throat stopper for shaft furnaces, in particular blast furnaces with two hoppers of which an upper hopper is rotatable through a drive device, the upper hopper is designed, by a stationary hood equipped with charging flap valves, as a sluice chamber to be closed pressureproof. For sealing the stationary hood relative to the rotatable upper hopper, there is disposed, at the hood, a peripheral flexible inflatable bellows. The bellows can be pressed against the wall of the upper hopper pneumatically or hydraulically. While material is being charged in the upper hopper, one of the charging valves is open and the bellows is pressureless. During, or shortly after, the charging, the uppr hopper is rotated. For filling the lower hopper, the valves of the upper hopper are closed, bellows is inflated, and the upper sluice chamber is pressurized.

    摘要: A method for manufacturing a film resistor for use as a thermal conductivity detector, particularly for gas analyzers. The film resistor is composed of a carrier of insulating material and of a thin resistance layer, preferably composed of platinum, that is applied to the carrier by cathode sputtering in an atmosphere inert gas. The resistant layer and the carrier are cleaned proceeding from the metallized side using an argon sputtering process. The film resistor is then coated with at least one plasma-enhanced CVD layer for the purpose of protection against aggressive gases.

    摘要: In a friction bearing system for a rapidly rotating shaft of an apparatus for measuring the optical absorption of a sample under analysis by way of an optical radiation source projecting a beam on the sample, the chopper system for the periodical interruption of the beam includes a rotatably mounted chopper disk provided with light-admitting openings and a controlled-speed drive system, as well as a radiation detector for the light affected by the sample. Both ends of the shaft fixedly joined to the chopper disk are provided with pivots corresponding to bushes, one of which is held by a spider which is affixed to the housing part that holds the other bush. The spider is provided with a bore running at an angle to the shaft, and the longitudinal axis of this bore intersects the axis of rotation of the shaft. A magnet is held for longitudinal displacement in the bore and its field acts upon a ring disposed on the shaft in order to assure the quiet and wear-free spinning of the chopper disk.
