  • Patent number: 6314714
    Abstract: A device for producing spun yarn by means of an airflow acting in a twisting manner on the fibers of an untwisted sliver (1) as the sliver is being conducted into and through a spindle assembly (3). The spindle assembly (3) comprises a spindle head portion (5) which conically tapers toward a spindle inlet opening (2) and is rotatable independently of a spindle core portion (7) through which the yarn is withdrawn. The device suppresses any tendency of the yarn strength to decrease at high, increasing numbers of spindle revolutions.

  • Patent number: 6314719
    Abstract: The ignition system includes an optical source capable of producing light having physical characteristics sufficient for optically driven chemical disassociation of a hydrogen peroxide oxidizer; and, an optical delivery system for providing optical delivery of light from the optical source to a combustion chamber. The ignition system is used for a propulsion producing engine having a combustion chamber for the introduction of a fuel and a hydrogen peroxide oxidizer. The initiation of combustion is produced by the non-linear, optical interaction of the produced light with a fuel and the oxidizer present in the combustion chamber, thereby leading to molecular disassociation of the oxidizer such that there is initiation of combustion.

  • Patent number: 6314723
    Abstract: In order to check the functional capability of a three-way catalytic converter of a lambda-controlled internal-combustion engine, the efficiency of the catalytic converter is determined in a conventional way by determining the oxygen storage capability of the catalytic converter. In order to be able to adjust the efficiency with regard to temperature changes, a substitute value for the temperature in the catalytic converter is calculated. Using this substitute value, the efficiency, which has been determined for the catalytic converter, is adjusted for temperature influences. The measure of the functional capability of the catalytic converter thus obtained is accurate even after non-steady-state operating phases of the internal-combustion engine when the catalytic converter is not yet isothermal.

  • Patent number: 6314724
    Abstract: An air-fuel ratio controller for an internal combustion engine with a catalytic converter in an exhaust passage has an air-fuel ratio sensor, an engine sensor, and a control unit. The air-fuel ratio sensor produces a signal indicative of an air-fuel ratio of an exhaust gas in the exhaust passage on an upstream side of the catalytic converter. The engine sensor produces a signal indicative of misfiring of the engine. The control unit is operatively coupled to the air-fuel ratio sensor and the engine sensor. The control unit computes an estimated quantity of oxygen to be stored in the catalytic converter based on the signal from the air-fuel ratio sensor, and determines if the engine is misfiring based on the signal from the engine sensor.

  • Patent number: 6314729
    Abstract: A specific type of hydraulic fan drive system is provided for engine drive machines, such as on road and off road machines, such as buses, construction equipment, agricultural equipment, and so on. The hydraulic fan drive systems turn a cooling fan (39) which provides airflow to cool the engine on such machines. This system uses a proportional pressure reducing valve (34) (or combination of valves providing a pressure reducing function) between the pump (12) and the fan motor (38). This valve (34) or (combination of valves) controls the pressure drop across the fan motor (38) based on a control signal from an electronic controller (50). The valve allows as little or as much flow to pass as is required to maintain this pressure drop at the load (the fan motor (38)).

The electric motor is used to drive a rotating-vane, rotary compressor that provides positive displacement suction on the device being evacuated of refrigerant. The vacuum pump further includes an external cooling system positioned about the housing to dissipate heat that builds up within the housing during periods of low refrigerant flow. The external cooling system includes tubular fins contained within a shell and held in abutting contact with an outer surface of the housing and a fan for forcing cooling air flow over and through the fins.

  • Patent number: 6314750
    Abstract: A heat pump air conditioner has a heat exchanger, a separator for separating refrigerant discharged from the heat exchanger into gas refrigerant and liquid refrigerant, and a compressor. Gas refrigerant in the separator is sucked into the compressor through a gas suction pipe. Oil-dissolved liquid refrigerant in the separator is also sucked through an oil return hole formed at a bottom of the gas suction pipe into the compressor. At the time of starting the air conditioner, when it is judged that a surface of liquid refrigerant in the separator is rapidly lowered to the oil return hole, a rotational speed of the compressor is controlled so that an amount of refrigerant discharged from the compressor is decreased. As a result, the surface of liquid refrigerant is kept higher than the oil return hole, and oil shortage of the compressor is restricted.

  • Patent number: 6314751
    Abstract: A chilling apparatus for chilling a liquid in a container includes a compartment sized to accept and retain the container; and a coolant receptacle adjoining a side portion of the compartment, for retaining a coolant, e.g., an ice/water mixture. The adjoining side portion has at least one aperture that allows the coolant to flow through to enter the compartment and surround the container therein. The liquid in the container is rapidly chilled via heat transfer between the container wall and the coolant when the container is rotated within the compartment. The rotation may be performed manually, e.g., via a holding member and hand-crank attached to the top of the container, or automatically via an electric motor. The apparatus is particularly useful for chilling canned beverages. The apparatus can be configured to impart wobbling rotation to the container to achieve even faster chilling times.

  • Patent number: 6314752
    Abstract: A mass and heat transfer device uses a substantially vertical surface to separating a first fluid space from a second fluid space with the first fluid space containing a downward flowing liquid in at least a partially flooded state and an upward flowing gas contained at least partially within the downward flowing liquid. A fluid distribution surface with one or more apertures is provided within the first fluid space with the apertures controlling the downward passage and distribution of the downward flowing liquid and the upward passage and distribution of the upward flowing gas. A heat transfer fluid is used in the second fluid space for heat transfer with fluids in the first fluid space. The fluid distribution surface can be used in a horizontal, vertical or angled position and in annular, cylindrical, and hexahedral forms.

  • Patent number: 6314755
    Abstract: The process and the apparatus serve for the low-temperature fractionation of air in a rectification system that has at least one pressure column and one low-pressure column. Feed air is compressed to a first pressure p1 in a first compressor, purified in a purification stage, cooled and at least in part introduced into the pressure column. At least one liquid fraction from the pressure column is fed into the low-pressure column. A nitrogen-rich fraction from the low-pressure column is warmed and mixed with feed air. The warmed nitrogen-rich fraction is mixed with the feed air downstream of the feed air purification stage. The mixture of feed air and nitrogen-rich fraction is further compressed in a second compressor to a second pressure p2 which is higher than the first pressure p1.

    Abstract: After a film made of SiO2 is formed on at least a part of a bonding surface of a first glass member, a part of or the whole bonding surface being formed with a metal film, a second glass member is hot-pressed against the bonding surface at a predetermined pressure and a predetermined temperature. As the second glass member is hot-pressed by way of the SiO2 film against the bonding surface of the first member made of glass or the like having its bonding surface formed with a metal film, the two glass members are firmly bonded together, the bonding surface would be less likely to peel off, and the metal film would not be damaged.
