A metallic ingot for impact pressing includes a contact surface of the metallic ingot to contact a male mold in impact pressing having a maximum height roughness Rz of 20 m to 50 m and an average length of a roughness curve element RSm of 150 m to 400 m, the male mold being to be used in combination with a female mold in the impact pressing.

The invention relates to a thermoplastic structure comprising at least one layer consisting of a composition comprising a copolyamide of formula X/10.T/Y, wherein: X represents either the residues of an aliphatic amino acid comprising between 8 and 18 carbon atoms, or a lactam, or the unit X.sub.1.X.sub.2 representing the residues resulting from the condensation of an aliphatic diamine comprising between 6 and 18 carbon atoms and a (cyclo)aliphatic diacid comprising between 6 and 18 carbon atoms; 10.T represents the residues resulting from the condensation of a decanediamine and terephthalic acid; and Y represents the residues resulting from the condensation of an aliphatic diamine comprising between 9 and 14 carbon atoms and an aromatic diacid, Y being different from the unit 10.T; the molar proportion of 10.T units in the copolyamide being higher than 0%; the molar proportion of Y units in relation to the group of 10.T and Y units being between 0 and 30%; and the proportion of X units being between 0.4 and 0.8 mole for a mole of semi-aromatic units 10.T and Y.

A device for coating a stent, including a holder for the stent, a spraying unit comprising a spray mandrel and an air nozzle. The spray mandrel, the air nozzle and the holder are configured and disposed relative to each other such that the spray mandrel projects from one side into the stent during coating and the air nozzle projects into the stent from the opposing side. A method for coating a stent employs the device. Stents that can be obtained according to the method.

A paper tube that functions as a core of a rolled sheet, the paper tube includes an inside base paper layer at an inside peripheral surface of the paper tube; and an outside base paper layer at an outside peripheral surface of the paper tube, polyphenol and glycerin being impregnated in at least one of the inside base paper layer and the outside base paper layer.

A metallic ingot for impact pressing includes a contact surface of the metallic ingot to contact a male mold in impact pressing having a maximum height roughness Rz of 20 m to 50 m and an average length of a roughness curve element RSm of 150 m to 400 m, the male mold being to be used in combination with a female mold in the impact pressing.

The present disclosure relates to extrusion coating systems, extrusion coated substrates, and processes for making the same. In some aspects, extrusion coating systems as described herein may include an at least partially insulated outlet wall, which may facilitate production of coated substrates exhibiting a very desirable surface texture and appearance. Coated substrates of the present invention may be utilized in a variety of end applications, including, but not limited to, interior and exterior construction materials for homes, buildings, and furniture.

A fluid applicator tool that includes an applicator portion including a pair of arcuate clamping members that each include an inner radial portion and an outer radial portion, an absorbent media extending along the inner radial portion of each arcuate clamping member, and a hinge coupled between the pair of arcuate clamping members. The hinge is operable for rotating the pair of arcuate clamping members relative to each other for positioning between an open position and a closed position. The pair of arcuate clamping members are oriented such that a through hole is defined therebetween when in the closed position.

An internal quench system for cooling pipes being coated is provided. The system comprises an internal quench lance having spray nozzles configured at one end of the internal quench lance. There is also provided wheels and retractable supports to support the internal quench lance without hindering the movement of the pipes. Each retract support is provided with a liquid coolant supplying means to provide liquid coolant to the internal quench lance. A process for using the internal quench system for cooling pipes being coated is also provided.

A hose is provided comprising a rubber backing layer directly bonded to a continuous polyamide layer without an intervening adhesive layer, wherein the hose exhibits increased low and high temperature capability and decreased permeation compared to standard automotive refrigerant hoses.
