  • Patent number: 5471764
    Abstract: An oven for drying the sealing compound on beverage and food can ends utilizes a prior art serpentine track along which a line of abutting can ends is conveyed through a drying chamber in which heated drying air is directed against the edges of the can ends through a plurality of linear nozzles. The improved apparatus of the present invention utilizes a drying chamber which substantially surrounds the track and includes a plurality of nozzles which direct a substantially uniform flow of drying air against all sides of the line of can ends. The improved apparatus is particularly effective in drying lining compounds on steel food can ends, but is suitable as well for the treatment of aluminum beverage can ends.

  • Patent number: 5471763
    Abstract: A nozzle attachment for a hair dryer has a cylindrical element for connecting a flow-directing member to the nozzle of a hair dryer. The flow-directing member deflects the air coming from the hair dryer by a certain acute angle. The flow-directing member is rotatable relative to the cylindrical element. Vanes are provided within the flow-directing member. They are slanted to the direction of air flow from the hair dryer, so that impingement of air on the vanes causes the flow-directing member to rotate thus providing air flow having a continually varying flow direction.

  • Patent number: 5467600
    Abstract: A thermal cycling system comprising an evaporator and a radiator and two separate conduits extending between the evaporator and the radiator to form a closed cycle. The evaporator is arranged to receive thermal energy available around the evaporator and the radiator radiates heat of the fluid medium flowing from the evaporator to the radiator. A power-free engine is arranged on the first and second conduits and comprises actuating pistons, at least one pressurizing cylinder, and a crankshaft operatively interconnecting the actuating pistons and the pressurizing piston. The arrangement is such that the actuating pistons are moved by the high pressure of the fluid medium in the evaporator and thereby actuate the pressurizing piston. The high pressure fluid medium is controlled such that it flows through the actuating cylinders to the radiator and radiates heat there at.

  • Patent number: 5465578
    Abstract: A thermoelectric cooler for cooling a sample of hot, continuously flowing gas involves a mechanical heat flow path passing from the flowing gas through a heat-exchanging tube channeling the gas, a heat-conductive block housing the tube, a thermoelectric element having a cold side abutting the block, a heat sink abutting a hot side of the thermoelectric element, and cooling air streams passing through slots in the heat sink. The heat sink is a unibody, jointless metallic body having relatively thin fins defining the slots. A high pressure blower drives turbulent air streams through the slots of the heat sink, and a thermal switch is disposed on the heat sink near the hot side of the thermoelectric element.

  • Patent number: 5457895
    Abstract: The invention permits the application of an identifying mark onto a freeze-dried tablet without the need for application of pressure or for printing directly on the tablet. The invention comprises the preparation of a freeze-dried unit that is embossed with an identifying mark such as a manufacturer's logo, medicinal component strength, or other information relating to the unit. The desired identifying mark is first embossed onto the base of a container such as a blister pocket. Liquid suspension is then filled into the container and freeze-dried therein. The resulting freeze-dried unit in the container is thereby embossed with substantial copy of the identifying mark that was embossed on the base of the container. The embossed identifying mark on the base of the container remains thereon as well, providing at reduced manufacturing cost the added ability to learn the identifying mark on the enclosed freeze-dried unit without opening the blister pack.

  • Patent number: 5456022
    Abstract: A drier having a boxlike housing (12) for receiving a hopper (13) therein which contains a batch of wet sludge. The hopper (13) cooperates with the housing, when closed therein, to define a closed air recirculation system which supplies dry pressurized warm air into an air-receiving chamber (79) located at the bottom of the hopper. The air passes upwardly through a perforated bottom wall (78) into and through the sludge to remove moisture therefrom. The moist air passes upwardly through the open top of the hopper, through a filter and is supplied to a drying unit (34) located in the housing for removing moisture therefrom, which moisture is externally discharged. The drying unit resupplies the dry air back to the drying chamber formed in the hopper.
