Abstract: Overmolded inserts and methods for forming the same The present disclosure is directed to overmolded inserts (100) with reduced internal residual stress and corresponding methods for forming the overmolded inserts. The overmolded inserts have a polymer housing; metal or metal allow tapered insert (104, 302) and a compression element (106, 304) disposed between the housing and the distal end of the tapered insert. During formation, the tapered insert and compression element are placed within a mold. The polymer housing material is heated and filled into the mold. As the polymer housing cools, the compression element is compressed between the polymer housing and the tapered insert. The overmolded inserts formed have reduced internal residual stress relative to a corresponding insert formed from non-tapered insert.

Abstract: A foam material having one glass transition temperature (Tg) and made from an immiscible composition having at least two glass transition temperatures (Tg) by an extrusion process wherein said composition (C) comprises at least one polyarylene (P1) polymer, wherein more than 50% by moles (moles %) of the recurring units of said (P1) polymer are recurring units (R1) consisting of an arylene group, wherein said arylene group is a hydrocarbon divalent group consisting of one core composed of one benzene ring or of a plurality of benzene rings fused together by sharing two or more neighboring ring carbon atoms, said benzene ring being optionally substituted, wherein each of said arylene group is bound to two other arylene groups of neighboring recurring units (R1) through a first C—C bond (E1) and a second C—C bond (E2), wherein at least 20 moles % of recurring units (R1) are kink-forming arylene units (R1-b), the remainder being rigid rod-forming arylene units (R1-a) different from aryleneR1_b units, wherein in

Abstract: A shut-off device for progressive regulation of the flow rate of a fluid flowing in a pipe includes a main shut-off member which is able to pivot independently about a spindle passing through the pipe in order to close the latter, and at least one drive flap able to pivot about the spindle and act mechanically on the main shut-off member in such a way as to turn it about the spindle. The main shut-off member also being traversed by at least one orifice that can be closed by at least one shut-off flap, which flap can also pivot about the spindle, is integral with the drive flap and can regulate the rate of flow of the fluid through the orifice. The main shut-off member only begins to pivot about the spindle, from an initial closed position, when the drive flap is at a predetermined non-zero angular distance &phgr; from the said member, thus allowing the fluid to flow only through the orifice until the main shut-off member begins to open.
