    Abstract: Novel thin-walled thermoplastic or thermoset pipes of at most 5 millimeters in thickness which can withstand a varied range of internally generated and/or applied pressures up to at least 5 bars, preferably at least 20 bars, for utilization within, primarily, liquid transport systems. Such pipes are improvements over standard metal (i.e., steel, lead, and the like) pipes due to construction costs, shipping costs, implementation costs (particularly underground), flexibility (and thus modulus strength allowances) to compensate for underground movements (i.e., earthquakes and tremors), non-rusting characteristics, reduced crack propagation possibilities, and ease in manufacture. Such pipes are preferably reinforced with specific textile reinforcement materials that permit a lower thickness of plastic to be utilized than is generally required to withstand high pressure situations and also serve to prevent propagation of any cracks which may develop within the thermoplastic or thermoset materials.

An elongated coupling member has a ring part formed integrally therewith, and is coupled to the cap as the ring part is engaged in the annular groove. The cap and the coupling member are each formed of electroconductive resin, and the surface resistance from the cap to the vehicle is set to be greater than or equal to 1×1012 &OHgr; and less than 5.30×1012 &OHgr;. Hence, when the human body is brought into contact with the cap, static electricity in the human body is discharged to the vehicle side, and no shock is imparted to the human body. In addition, the amount of residual charge also declines without causing secondary spark discharge.

  • Publication number: 20010048989
    Abstract: A flexible insulating duct excellent in both the noncombustibility and insulating characteristics as well as productivity, and formed by spirally winding a belt-like body which is obtained by wrapping glass wool or some other insulating material with a noncombustible cloth or some other noncombustible sheet type material. When the belt-like body is spirally wound, a preceding end portion thereof and a following end portion thereof are bonded to each other so that the noncombustibility of a final product is not lost, or joined to each other firmly via a noncombustible joint member.

  • Patent number: 6309423
    Abstract: A web of continuous filaments which are made of at least one semi-crystalline polymeric component covalently bonded as a linear block copolymer with or blended with one or more semi-crystalline or amorphous polymeric components. The filaments are intermingled together to form a porous web of filaments, the filaments having multiple contact points with each other within the web. The filaments are bonded at the contact points without requisite for added adhesive binders, adjuncts or post extrusion melt processing. The web may be bioresorbable. The web may also be provided in forms with relatively high cohesive shear strength. The polymeric components of the filaments exist, at least temporarily, in a homogenous substantially phase miscible uncrystallized state.

  • Patent number: 6306474
    Abstract: The present invention relates to a carbon fiber reinforced plastic member provided with high-elongation fiber bundle regions, which are uni-directionally aligned and separately disposed within the plastic member. The plastic member provides a carbon fiber reinforced plastic of lightweight, high strength and high modulus that is safe. Even if it breaks, it shows little scatter of fragments or exposure of dangerous fracture surfaces. Preferably, the high-elongation fiber at break has an elongation exceeding about 10%.

  • Patent number: 6306664
    Abstract: A method to produce arrays of compounds for concurrent testing is described. Two formats are described using porous rods or porous sheet materials. In one format, the compounds of the array are immobilized onto porous rod elements. In the second format, the compounds are immobilized as lines on a sheet of porous material. In both cases, a bundle is formed by radial compression of the rods or spiral wrapping of the sheet. A sheath is applied to the bundle, and arrays are cut as slabs. Each synthesis or application step to create an array element is used to fabricate multiple arrays. Relatively high-density arrays can be produced with current printing technologies. The method is particularly suited to mass production of arrays.

  • Patent number: 6274209
    Abstract: A venting cap (1) has a cavity (7), at least one first passage (4) for fluids connecting the cavity (7) with the inside of the container, at least one second passage (5.1, 5.2, 5) for fluids connecting the cavity (7) with the outside of the container, and a liquid-absorbing mass (8) arranged within the cavity (7). The liquid-absorbing mass (8) acts, after absorption of liquid, as a selective filter prohibiting the passage of liquid, but permits the passage of gas. This ensures the foolproof selective permeation of gas but not of liquid. Venting properties remain unaltered even at extreme conditions of transportation and storage.
