One aspect of the invention provides a system including: a length of energy-dissipative tubing; a first sealing device coupled to a first end of the length of energy-dissipative tubing; and a second sealing device coupled to a second end of the length of energy-dissipative tubing. Exposure to one or more selected from the group consisting of: fault currents or lightning strikes at an exposure point along the length of energy-dissipative tubing will produce arcs at the exposure point and at least one of the first end and the second end.

An air-induction system of an engine includes a hose assembly. The hose assembly includes an elastomeric hose having a circular cross section when in a natural state, and a deformable sleeve received around the hose and configured to create an indentation in the hose for part clearance. The sleeve has an end section having a circular cross section and an intermediate section in which the sleeve projects radially inward into a sidewall of the hose such that the hose is deformed from the natural state to a deformed state in which the sidewall is deformed radially inward creating the indention and a non-circular cross section of the hose at the intermediate section.

A hose is provided capable of meeting fireproof requirements per AS1055 under no flow condition. The hose has multiple layers including a yttria-stabilized zirconia (YSZ) flexible ceramic substrate layer disposed between first and second silicone rubber layers.

A tube includes a corrugated metal tubular member; and a first covering part that covers the outside of the tubular member, and forms a braided structure using a resin string member of which at least a part is covered by a metal having lower electrical resistance than that of a metal forming the tubular member. The tube can also include a third covering part made of an insulating resin arranged between the tubular member and the first covering part, and covers the tubular member, wherein the first covering part covers the third covering part.

A through-air apparatus for drying or bonding paper, tissue, or nonwoven webs is provided. The apparatus includes a web-carrying structure configured to move and a first component having at least one sealing element adjacent the web-carrying structure, where the sealing element is configured to reduce the infiltration of ambient air into the through-air apparatus. The apparatus also includes at least one channel configured to direct air to the sealing element to reduce the infiltration of ambient air into the through-air apparatus. A method of operating a through-air apparatus for drying or bonding paper, tissue, or nonwoven webs is also provided. The method includes directing air to a sealing element to reduce the infiltration of ambient air into the through-air apparatus.

One aspect of the invention provides a system including: a length of energy-dissipative tubing; a first sealing device coupled to a first end of the length of energy-dissipative tubing; and a second sealing device coupled to a second end of the length of energy-dissipative tubing. Exposure to one or more selected from the group consisting of: fault currents or lightning strikes at an exposure point along the length of energy-dissipative tubing will produce arcs at the exposure point and at least one of the first end and the second end.

The present invention relates to a multilayer tubular structure (MLT) intended for the transport of fluids, in particular of petrol, especially alcohol-containing petrol, comprising, from the outside inwards, at least one barrier layer (1) and at least one inner layer (2) located below the barrier layer, said inner layer (2), or all the layers (2) and the other optional layers located below the barrier layer, containing on average from 0 to 1.5% by weight of plasticizer relative to the total weight of the composition of the layer (2) or to the total weight of all the compositions of the layers (2) and the other optional layers located below the barrier layer, respectively, said inner layer (2) predominantly comprising at least one polyamide of aliphatic type or consisting of more than 75% of aliphatic units, said aliphatic polyamide being chosen from: a polyamide denoted A, having a mean number of carbon atoms per nitrogen atom, denoted C.sub.A, of from 4 to 8.5, advantageously from 4 to 7; a polyamide denoted B, having a mean number of carbon atoms per nitrogen atom, denoted C.sub.B, of from 7 to 10, advantageously from 7.5 to 9.5; a polyamide denoted C, having a mean number of carbon atoms per nitrogen atom, denoted C.sub.C, of from 9 to 18, advantageously from 10 to 18; with the proviso that when said inner layer (2) comprises at least three polyamides, at least one of said polyamides A, B and C is excluded.

Hoses include a tube, a reinforcement layer disposed outwardly from the tube, and a cover layer disposed outwardly from the reinforcement layer. The cover layer may be based on a first elastomeric blend of a first chlorinated polyethylene and chlorosulphonated polyethylene, a first flame-resistant composition, and a peroxide/sulfur curing system. The tube may be based upon a second elastomeric blend of a second chlorinated polyethylene and ethylene vinyl acetate rubber, a second flame-resistant composition, and a peroxide curing system. The first flame-resistant package and the second flame-resistant package includes one or more ingredients selected from the group consisting of antimony oxide, zinc molybdate/magnesium silicate complex, magnesium aluminum hydroxy carbonate, and aluminum trihydroxide. In some aspects, the hoses meet the testing performance requirements of EN 45545-2, HL2/R22 category standard, and EN854 type 2TE standard.

The present invention relates to a multilayer hollow molded body, which has sufficiently high barrier properties, burst resistance and heat resistance, is also excellent in terms of impact resistance, and can be preferably used as a fuel transportation piping material for transporting high-temperature liquid fuel, etc. The multilayer hollow molded body of the present invention has at least one aliphatic polyamide layer (A) and at least one barrier layer (B), wherein the aliphatic polyamide layer (A) consists of a resin composition comprising an aliphatic polyamide (a) as a main component, and the barrier layer (B) consists of a resin composition comprising an ethylene-vinylalcohol copolymer (EVOH) and a semi-aromatic polyamide (b).

A flexible hose comprising: a flexible conduit for carrying a pressurized fluid; a flexible inner support for supporting the conduit; and a compression layer surrounding the flexible conduit.
