  • Patent number: 5692370
    Abstract: An assembly includes a gas turbine with an inlet, a combustion air compressor with an outlet, a combustion chamber, and a common wall between the outlet of the compressor and the inlet of the turbine. A gas valve has a transverse bulkhead serving as a transverse separating wall on at least one side of the common wall, and a slide covering the transverse bulkhead and the common wall in the vicinity of the compressor. The slide has slots formed therein for alternatingly closing corresponding slots formed in the common wall and in the transverse bulkhead.

  • Patent number: 5639124
    Abstract: The invention concerns an array of tabs (3) projecting out beyond the edge (1) of the main surface (2) of files, card-index cards, etc., particularly tabs designed for written annotations. In order to provide variable-design tabs (3) which do not involve the loss of material, the invention proposes that the tab (3) is folded over to bring it out of the main surface area (2) of the file or card to expose an area down to the fold line (11).

  • Patent number: 5267784
    Abstract: Evaluation circuit for processing wheel speed signals and controlling brake pressure compares control cycle times to detect when wheel vibrations are present. When cycle times are approximately equal, oscillations are present, and the system is switched to a special operating mode in which pressure reduction is prevented in subsequent control cycles, and pressure build-up or pressure maintenance is initiated in a phase shifted manner.

  • Patent number: 5120690
    Abstract: For a complete utilization of used DeNOx catalysts contaminated with fly ash, the catalyst is crushed to a particle size of usually less than 500 microns, admixed with the ash of a molten ash firing chamber of a coal power plant at weight ratio of usually at least 9 parts molten ash to 1 part catalyst where the catalyst is dissolved in the molten ash at a temperature generally above 1460.degree. C. The resulting molten ash chamber granulated material can be utilized in the usual way, for example in the construction industry, since no pollutants, especially no compounds of tungsten, molybdenum, vanadium and arsenic are eluted into the environment.

  • Patent number: 4583412
    Abstract: A variable-velocity drive is provided which serves to so control the periral velocity of a window cutter roller in an envelope machine working from the reel that, irrespective of the developed length of such roller, the velocity of the window cutter is the same as that of the paper web for the time that such cutter is operative on such web. To this end, the variable-velocity drive is basically devised from a number of universal joints interconnecting shafts whose axes intersect one another at an angle of up to approximately 45.degree.; the universal joints are so offset from one another in rotation that the variations or irregularities arising in the discrete joints are superimposed upon one another so as to have an amplifying effect. Since any one such universal joint arrangement passes through two velocity maxima and two velocity minima per revolution, gearing is provided on the input and output side to make the universal joint arrangement run at half the cycle speed.
