  • Patent number: 5603167
    Abstract: A pipe coil is heated in the furnace of a heat treatment apparatus, The oil adhered to the inside of the pipe is vaporized by this heating, In this state the oil removing gas is fed at one end into the pipe which gas is in the high temperature enough to maintain the vaporizing condition of the oil.

  • Patent number: 5590478
    Abstract: An inside-out heating method provides efficient and economical heating of wet cement during the curing phase in building structures. Hollow building blocks and their cement joints may be heated by applying forced hot air injected at the base of the wall. The hot air rises up through the wall and out of the open end of the top course of block by the chimney effect of the hot air rising through the ducting created by the aligned vertical passageways in the hollow blocks. The hot air is distributed through the wall by a manifold and injection tubes which provide air ducting from a heat source, such as a forced air propane heater. Temporary holes are broken through a low level course of block to receive the hot air injection tubes. After the cement has fully dried, the injection tubes are removed and the temporary holes are filled in with cement.

  • Patent number: 5570518
    Abstract: There is disclosed a method for drying a cylindrically-shaped substrate having a wet coating thereon which is oriented in a substantially vertical direction comprising directing a plurality of gas streams at a tangential angle against the substrate surface around the circumference of the substrate, wherein there is a plurality of imaginary lines on the substrate surface which are parallel to the longitudinal axis of the substrate, one imaginary line intersecting one gas stream, wherein each gas stream is directed upwards at an acute angle with the intersecting imaginary line, thereby reducing the gas pressure above a portion of the substrate surface which promotes drying of the coating.

  • Patent number: 5513446
    Abstract: A method and an apparatus serve for drying industrial barrels (60). The industrial barrels (60) are positioned on an inclined base (12, 20) and are enclosed by a pressure-tight vacuum hood (30). A suction pipe (40) that is connected with the vacuum hood (30) extends through a bunghole (63) provided in the tilted barrel (60) at its lowest point (71) where the residual liquid quantity (70) gathers. A heating rod (55) is arranged inside the suction pipe (40). The suction pipe (40) is connected to a vacuum pump (48). The heated suction pipe (40) removes from the interior of the barrel (60) at first die liquid residual liquid quantity (70), and then the vaporizing residual liquid. Compared with conventional methods, using hot steam for drying, this method leads to cost savings and an improved drying effect (FIG. 1 ).

  • Patent number: 5469635
    Abstract: The baby bottle dryer comprising a base plate formed in a dish-like configuration having a flat lower surface at the central extent and curved upwardly extending side walls, a central tube extending upwardly to an extended elevation above the periphery of the base, a plurality of spaced apertures formed in the tube, the apertures having cylindrical surfaces extending upwardly from the tubular member at an angle of about 30 degrees from the horizontal, a plurality of rods, each rod being hollow with an opened first end and closed second end and with a plurality of small holes located along their length thereof, the external diameter of the being such as to be removably positioned within the apertures of the tube and adapted to receive thereon a baby bottle to be dried, a fan located in a lower extent of the tube with means to couple the fan to a source of potential, the source of potential being a pair of batteries with a switch located on the exterior surface of the tube for coupling the batteries to the fan

  • Patent number: 5394621
    Abstract: A garment dryer having a plurality of segments which are connected together to form the shape of a garment. The garment dryer has a body assembly having two or more body segments to which is connected a pair of extremity assemblies, each of which may be formed in two or more parts. The extremity assemblies may be either arm assemblies or leg assemblies, or both. The arm assemblies may be used with the body assembly to dry garments such as sweaters and sweatshirts. The leg assemblies may be used with the body assembly to dry garments such as pants. The arm and leg assemblies could be used together with the body assembly to dry garments such as jumpsuits. A garment is placed over the assembled garment dryer and is allowed to dry by hanging it either vertically or horizontally. Each of the segments of the garment dryer will nest within one of the other segments so that the entire garment dryer can be compactly stored.

  • Patent number: 5361516
    Abstract: Device and method for drying pants wrinkle-free by closing the waist and leg openings of the pants and by blowing pressurized air into the pants through an opening in an impermeable member which supports the waist of the pants. Pressurized air inside the pants simultaneously stretches the pants free of wrinkles and causes air to flow through the permeable pants to carry away moisture. A portable hair dryer preferably generates a static pressure of from 0.1 inches (2.5 mm) of water to 0.3 inches (7.6 mm) of water in order to stretch wrinkles from the pants without overly stretching any part of them. The impermeable member supporting the pants is preferably an adjustable disk assembly capable of fitting a large size range of pants, which is hung from a clothes line by a cord with a hook.
