  • Patent number: 4287672
    Abstract: A method and apparatus for drying pieces in bulk, such as metal screws being electrolytically galvanized. The pieces are charged in a rotating perforated barrel through which drying air is passed. The barrel is positioned in a drying chamber which also contains a ventilator for circulating the air, an air heater and a dehumidifier. These components are arranged so that dry air is drawn through the barrel and the charge by vacuum from the portion of the barrel not filled by the charge. Flexible seals between the barrel outer casing and a suction box direct the flow of air substantially completely through the charge.

The mountable tube is produced by cylindrical hammering of a steel body which may be provided interiorly thereof with a perforated insert body incapable of being deformed under the hammering process, but capable of being held within said mountable tube subsequent to completion of the hammering operation. The insert body is arranged to support the mountable tube on the textile spindle.

  • Patent number: 4287712
    Abstract: A textile yarn processing machine, such as a two-for-one twister, is provided with a pneumatically operated yarn threading mechanism for initially threading a yarn through a hollow spindle of the textile processing machine during a thread-up operation and an improved self-threading yarn brake mechanism for applying tension to the yarn as it passes through the hollow spindle during operation of the machine. The improved yarn brake mechanism is constructed to cooperate with the threading mechanism to facilitate automatic threading of the yarn through the hollow spindle and is characterized in that the compressed air which is supplied to the threading mechanism during the thread-up operation also operates to move the yarn brake mechanism from an engaged position to a released position to thus automatically provide a clear path for threading the yarn through the hollow spindle.

  • Patent number: 4287714
    Abstract: A false-twisting system uses nipping type false-twisting apparatus designed to nip filament yarns between two intercrossing endless belts whose working surfaces are urged in the crossing region into engagement with each other.Monofilaments of a first multifilament yarn are wound fast round monofilaments of a second multi-filament yarn with combined S- and Z-twists to provide a crimped bundle of yarn closely resembling spun yarns.

  • Patent number: 4287715
    Abstract: A supersonic jet engine capable not only of developing sufficient power to accelerate up to supersonic cruise and maintain efficient operation at supersonic cruise, but also arrange to cruise at subsonic velocities with a relatively low specific fuel consumption. The engine is provided with a variable bypass passageway downstream of the compressor. Flow into the bypass passageway is controlled so that during low power setting the bypass passageway is closed so that all the gaseous flow is directed through the turbine. During higher power settings, the bypass passageway is opened to the extent that a selected portion of the gaseous flow is directed through the bypass passageway to bypass the turbine, so that the corrected flow to the turbine remains substantially constant for both high and low power settings of the engine. The turbine has first and second stages, with the first stage receiving all of the gaseous flow that is not directed through the bypass passageway.

  • Patent number: 4287716
    Abstract: An exhaust gas system for a multi-cylinder internal combustion engine, in which some cylinders are adapted to be effectively disconnected; the exhaust gas system includes in a common exhaust line, an O.sub.2 -probe and two series-connected catalysts while a separate exhaust gas line is coordinated to the cylinders adapted to be effectively disconnected; a control member operable as a function of load opens three separate branch connections from the separate exhaust line to the common exhaust line in such a manner that when all cylinders are firing, the branch connection terminating upstream of the O.sub.2 -probe is opened; the branch terminating in the common exhaust line between the O.sub.

  • Patent number: 4287717
    Abstract: This disclosure relates to a turbocharged low compression ratio diesel engine. An air by-pass is connected in parallel with the engine and is operable to by-pass a portion of the compressor output around the engine and into the exhaust manifold. A control is connected in the by-pass to regulate the amount of by-passed air, the control operating in response to the compressor output. The by-pass further includes means for heating the air flowing to the turbine to aid fuel combustion in the engine cylinders.

  • Patent number: 4287718
    Abstract: A condenser arrangement having a load bearing member hermetically coupled to the condenser's condensation chamber. Load transfer means are adapted to transfer the condenser vacuum load acting on the load bearing member to the turbine or turbine support in a manner to balance the condenser vacuum load acting on the turbine through the turbine exhaust. In the preferred arrangement means are provided to minimize contributions from the condensate to forces acting upon the load bearing member.

  • Patent number: 4287719
    Abstract: A compact, high-efficiency, J-tube carbon dioxide snow hood has a novel diffuser at the discharge end of the J-tube for providing a well-confined, concentrated snow deposit at a reduced exit velocity. The diffuser includes a pair of juxtaposed, axially upright cylindrical baffles which intercept the fine-particle snow discharge from the J-tube in a manner to create counterswirling currents of carbon dioxide snow. An upright cylindrical tube circumscribing the cylindrical baffles, and depending substantially beyond the lower ends of the baffles, forms a mixing chamber where the segregated counterswirling currents of carbon dioxide snow interact to form desired larger-particle snow which is then passed from the chamber in a confined, low velocity, downwardly directly discharge.

  • Patent number: 4287721
    Abstract: A concentrated saline solution is used to store solar energy for both heating and cooling. A small, uninsulated tank is used to store the desiccant solution so that the heat pump can operate at night or during extended periods when the sun is obscured. No vacuum or pressure refrigerant systems are needed. Reconcentration of the sorbent solution is accomplished by direct solar radiation.
