  • Patent number: 6074263
    Abstract: Methods of manufacturing ballasts and starter assemblies used in gas discharge lamps are disclosed. One embodiment of a starter assembly includes a one-piece plastic enclosure for a glow bulb which is used as a starter for a fluorescent lamp. The enclosure has a latching hinged lid, a partition wall to isolate the glow bulb leads, and integral strain relief. The glow bulb enclosure is preferably mounted inside a ballast assembly and the glow bulb leads are preferably ultrasonically welded to the ballast power supply wires. Methods of reducing manufacturing expenses by physically separating the glow bulb from other ballast components are also disclosed.

  • Patent number: 5118447
    Abstract: A method is disclosed for denitrification of nitrates and nitrates present in aqueous waste streams. The method comprises the steps of (1) identifying the concentration nitrates and nitrites present in a waste stream, (2) causing formate to be present in the waste stream, (3) heating the mixture to a predetermined reaction temperature from about 200.degree. C. to about 600.degree. C., and (4) holding the mixture and accumulating products at heated and pressurized conditions for a residence time, thereby resulting in nitrogen and carbon dioxide gas, and hydroxides, and reducing the level of nitrates and nitrites to below drinking water standards.

  • Patent number: 4760978
    Abstract: A plurality of electrically conductive wires is connected between two terminals and cross over each other at crossover points. Wire segments connect adjacent crossover points. All such adjacent connected crossover points have different potentials when a voltage is connected between the terminals. This forms a screen which protects an engine from damage caused by foreign objects carried into the engine intake. When a power source is connected to the terminals, the screen is heated to prevent the accretion of ice.

  • Patent number: 4155832
    Abstract: Coal or other solid carbonaceous material is contacted with an organic solvent containing both hydrogen and a transition metal catalyst in solution to hydrogenate unsaturated bonds within the carbonaceous material. This benefaction step permits subsequent pyrolysis or hydrogenolysis of the carbonaceous fuel to form gaseous and liquid hydrocarbon products of increased yield and quality.

  • Patent number: 4090944
    Abstract: A process for the depolymerization of coal which includes contacting coal with phenol and a Bronsted acid catalyst at elevated temperatures and pressures for a period of about 5 minutes. The liquid coal extract which results from this process can be subjected to hydrogenolysis to produce a liquid hydrocarbonaceous product oil.
