  • Patent number: 4220481
    Abstract: During the labeling of a vial, mislabeling can occur. The unwanted label is cleanly and economically removed by forcing the vial through a novel collet-cutter. The cutter has at least two cutting edges and two slots. The slots permit expansion of the diameter of the cutting edges during the passage of a vial. At least one of the edges of the slots is outwardly sharpened. Further, its cutting edges are at an angle to the incoming vial and have an internal diameter whereby the label is removed completely and cleanly when the vial is forced through the cutter.

  • Patent number: 4213752
    Abstract: A single step process for removing moisture from low rank coal using in-situ generated thermal energy by passing the wet low rank coal at room temperature into a moving bed of hot coal at a temperature in the range of from about 200.degree. C. to about 300.degree. C. at a rate to maintain partial combustion of the coal at atmospheric pressure, and in the presence of a gas at atmospheric pressure containing from about 5% to about 20% by volume of oxygen, the heat generated by the combustion being absorbed by the wet coal being fed to the system and being effective for drying the coal to the desired level, and separating the dried coal from the combustion zone, whereby the dry coal obtained is highly resistant to spontaneous combustion.

  • Patent number: 4209400
    Abstract: A method for removing oil from the surface of water where an oil spill has occurred, particularly in obstructed or shallow areas, which comprises partially surrounding a hovercraft with a floating oil-collecting barrier, there being no barrier at the front of the hovercraft, moving the oil-barrier-surrounded-hovercraft into oil contaminated water, and collecting oil gathered within the barrier behind the hovercraft through a suction line which carries the oil to a storage tank aboard the hovercraft. The invention also embodies the hovercraft adapted to effect an oil spill cleanup.

  • Patent number: 4177217
    Abstract: Dimethyldicyclopentadiene is continuously hydrogenated to tetrahydrodimethyldicyclopentadiene and then the latter is continuously isomerized to a missile fuel. Both the hydrogenation and the isomerization steps use a nickel on silica-alumina catalyst. The temperature of the hydrogenation is in the range of about 70.degree.-260.degree. C., and the temperature of the isomerization is in the range of about 200.degree.-280.degree. C. The space velocity of the hydrogenation is about 0.1 to about 2.0 volumes of the diene charged per volume of catalyst per hour and the space velocity of the isomerization is about 0.1 to about 3.0 volumes of the hydrocarbon charged per volume of catalyst per hour. The pressure range for hydrogenation is between about 200 psig to about 3000 psig and for isomerization between from about 10 psig to about 1500 psig. Hydrogen is present during the isomerization.
