  • Patent number: 4589889
    Abstract: A method and apparatus for removing noxious oxides of sulphur and nitrogen from a hot exhaust gas produced by burning fossil fuels and simultaneously producing a hot water stream essentially free of noxious acidic gases, suitable for district heating. The hot exhaust gas stream is fed to an absorber where it is counter currently contacted with a recirculation water stream, an inlet water stream and an alkali stream to cool the hot exhaust gas then absorb the noxious oxides. A first water line containing absorbed oxides leads from a catch try beneath the absorber middle section to a sub-atmospheric pressure stripper and a second water line leads hot recirculation water from the absorber bottom to a flash pan in the stripper. Due to the reduced pressure in the stripper the absorbed oxides are removed from the water and heat is transferred from the absorber to the stripper. All the heat energy required to operate the stripper is supplied to the system by the hot gases.

  • Patent number: 4588500
    Abstract: The present invention is directed to a fuel filter dehydrator apparatus for a fuel system which coalesces and retains residual water within the fuel filter. The device comprises a plurality of fuel filter dehydrator elements and a container for housing the filter elements. The container defines a fuel inlet and a fuel outlet for directing fuel through the filter dehydrator elements. Each of the filter dehydrator elements comprises a rigid, porous tube having a water retaining cellulose fiber sheet and water coalescing fiberglass layer wrapped therearound. The fiberglass coalesces water droplets in the fuel passing through the element and then releases the coalesced water to the cellulose fiber sheet. As the cellulose sheet becomes water saturated, its fluid permeability sharply decreases, automatically shutting off fuel flow therethrough. Residence of water in the fiberglass layer substantially adds to the water retaining capacity of each fuel filter dehydrator element.

  • Patent number: 4586094
    Abstract: A method and apparatus for initializing a data-recording media, particularly tape, by use of the same type of media drive used for data-recording purposes, in which the actual edge of the recordable field on the media is first located by a test read/write process and the media is then transported in a succession of passes across the transducing head, during each of which the head is periodically and selectively energized to write mutually-spaced marker bursts and servo-positioning bursts, with the transducing head being moved open-loop a distance corresponding to a half-track width between each media transport. During the first such pass, the marker bursts and servo-positioning bursts are located on the basis of tape travel distance, and on successive passes burst location is determined by sensing the previously-recorded marker and servo bursts and timing-out a predetermined distance therefrom by use of an internal clock.

  • Patent number: 4582548
    Abstract: The alloy is a nickel base, superalloy specifically intended for the making of castings which consist of a single crystal. The castings are intended for use under extreme conditions of high temperature and stress. The alloy, for the first time, achieves the desired characteristics of phase stability, high stress-rupture strength and resistance to oxidation while maintaining a sufficient temperature differential between gamma prime solvus and incipient melting temperatures, that it is practical to solution heat treat without unacceptable percentages of rejects due to failure either to completely solution the primary coarse gamma prime or to initiation of incipient melting. In a modified form the coated oxidation/corrosion resistance of the alloy is increased by the addition of a trace quantity of hafnium.
