  • Patent number: 4311500
    Abstract: The disclosure embraces a method of and apparatus for removing glass floods that may form on the tip section or orifice plate of a stream feeder, bushing or substrate from which normally flow streams of glass, the method and apparatus involving the application or delivery of a stream or streams of liquid carbonaceous or hydrocarbon material onto the glass flooded area, the liquid material being decomposed in an atmospheric environment or in an inert or nonoxidizing environment by the high temperatures of the feeder, bushing or substrate and the molten glass to release carbon particles which are effective to dewet the glass flood and remove the flood.
    Type: Grant

  • Patent number: 4065274
    Abstract: A pollution control system for reducing the presence of fine aerosol particles in stack gases from the manufacture of glass fiber wool-type products. After larger particles are removed from the forming fan gas, the gas is fed into a centrifugal fan and massive quantities of water are injected into the fan intake. The aerosol particles are agglomerated by impact with the airborne water droplets and the wet surfaces of the fan. The larger, coalesced or agglomerated particles are more readily susceptible to inertia-type separation from the air by either the action of the fan or in a later separation operation.

  • Patent number: 4028071
    Abstract: A pollution control system for reducing the presence of fine aerosol particles in stack gases from the manufacture of glass fiber wool-type products. After larger particles are removed from the forming fan gas, the gas is fed into a centrifugal fan and massive quantities of water are injected into the fan intake. The aerosol particles are agglomerated by impact with the airborne water droplets and the wet surfaces of the fan. The larger, coalesced or agglomerated particles are more readily susceptible to inertia-type separation from the air by either the action of the fan or in a later separation operation. It has been found that 1.5 or more gallons per minute (gpm) of injected water per thousand standard cubic feet per minute (scfm) of forming gas passing through each fan is effective to remove more than 40% of the fine, aerosol particles introduced into the fan and even larger amounts of water remove greater amounts of such particles.

  • Patent number: 4006079
    Abstract: A method of oil removal wherein glass fibers are formed from melted glass, sprayed with a binder, and collected on a conveyor in a continuous process. A woven scrim of continuous glass filaments is fed from a roll to the conveyor along with the glass fibers. The scrim and fibers pass under a sizing roll which compresses the fibers into a mat, and then through a curing oven to cure the binder. The scrim-reinforced glass fiber mat is cut into lengths, such as one hundred feet or two hundred feet, and rolled into rolls for eventual use as an oil absorbent primarily to clean up oil spills from oil tankers.
