  • Publication number: 20040050426
    Abstract: A damper valve includes a valve member for covering openings of communicating passages of a valve sleeve. The valve member is elastically deformed by a low flow rate of the hydraulic oil flowing from a second chamber to a first chamber of the valve sleeve and when a flow rate of the hydraulic oil flowing from the second chamber to the first chamber exceeds a predetermined value, the valve member is moved with the spool against urging force of a spring to widely open the openings of the communicating passages.

  • Publication number: 20040050428
    Abstract: A spring loaded valve member with a poppet on one end is disposed in a fuel tank with the inlet end connected to the filler tube. The valve member has a spool valve attached to the poppet. The poppet is opened by fuel discharging from a refueling nozzle and the valve member movement limited by a float operated latch such that fuel flows through the spool valve ports. Upon the float rising in the tank, the latch is released permitting the force of the flowing fuel to further move the valve member to close the spool valve.

  • Publication number: 20040050430
    Abstract: The invention is directed to a high pressure fluid processing device for shearing particles in a fluid mixture. The fluid processing device makes use of annular flow paths. For example, a fluid mixture can be separated into two flow paths which are introduced to first and second annular flow paths on opposite sides of a flow path cylinder. The two annular flow paths flow toward one another through the cylinder, and meet one another within the cylinder. An outlet extends through the cylinder where the two annular flow paths collide allowing the fluid mixture flowing down the annular flow paths to be expelled through the gap.

  • Publication number: 20040050438
    Abstract: An anti-backflow eductor has a resilient sealing sleeve disposed on a water port defining blind end tube. The sleeve has a thinner wall cross section at a discharge end to enhance sealing while facilitating increased water flow. The ports in the blind end tube extend into a radial tube flange at the tube's inlet end to facilitate water flow out of the ports between the sleeve and tube. A tapered seat in the housing, together with cross bars in the vents, reduces the air vent cross section and relative motion between sleeve and housing to reduce sleeve wear. The eductor comprises an anti-backflow housing and a venturi housing coupled together for relative rotation but being inseparable under normal conditions to inhibit venturi use without the anti-backflow function of the anti-backflow housing.

    Abstract: A flexible armoured pipe is built up of three layers, i.e. an impermeable liner (2a), an inner armouring layer (1a) and an outer armouring layer (3a). A flexible pipe, especially for offshore applications, is hereby provided, where the inner armouring layer is in contact with the fluid, which shall be transported in the pipe, while the outer armouring layer and the impermeable liner are in contact with the surroundings. This means that the inner armouring layer absorbs the hydrostatic pressure acting on the impermeable liner. Moreover, since no substantial restrictions to mass transport exist outside the impermeable liner, gases, which diffuse through the impermeable liner, will now be able to escape to the surroundings.

The &ggr;′ particles are preferably precipitated in a size of 2 pin or more with a proportion by volume of 0.25<(Vtot−V1)/(100−V1)<0.55 at the first temperature. The proportion by volume Vtot of the &ggr;′ particles will be at least 50%.

  • Publication number: 20040050465
    Abstract: A hot meal object is quenched after heat treatment. A hot gas stream comprising at least 20% by volume of hydrogen is taken from for example a carburising chamber (4) of a furnace (2). The gas is cooled by passage through a heat exchanger (16), and is compressed in a compressor (18). The compressor (18) has an aftercooler (not shown) to remove heat of compression from the gas. The cooled, compressed gas flows through nozzles (26) into a quenching chamber (6). The gas leaves the nozzles (26) at a velocity of at least 50 m/s and impinges upon the hot metal object so as to effect its quencing.

  • Publication number: 20040050469
    Abstract: The invention relates to a tire having a rubber tread of a cap/base configuration composed of a composite of a silica-rich tread cap layer running surface, and an underlying transition zone composite of a carbon black-rich intermediate layer positioned between the tread cap layer and a tread base layer. The combination of intermediate layer and base layer provide a beneficial graduated stiffness between the tread cap layer and the tire carcass. Significantly, the transition zone composite enables a significantly thicker carbon-black rich portion of the tread composite and an associated thinner silica-rich tread cap running surface. In one aspect, the intermediate layer of the transition zone composite can extend to and include a bottom portion of at least two of the grooves of said tread cap layer to support an associated tread lug therebetween.
