An air duct assembly attachable to a receiving port includes an air duct with an inner surface and an exterior surface connected to one another at a coupling fixture. A seal is connected and bonded to the coupling fixture. The seal extends axially from the coupling fixture and has a tip with an inner diameter smaller than the coupling fixture's inner diameter. A shell is connected to the coupling fixture and the seal. The shell extends axially from the seal and is connectable to the receiving port.

A seal part includes an elastic body that is in close contact with outer peripheral surfaces of a plurality of wires and an inner peripheral surface of a wire accommodation portion, and a rigid body that has an outer peripheral surface disposed to face the inner peripheral surface of the wire accommodation portion. The rigid body has a plurality of wire through holes allowing wires to coaxially pass through respectively. The elastic body includes first seal portions that respectively correspond to the wire through holes, and that are in close contact with the outer peripheral surfaces of the wires passing through the wire through holes, and a second seal portion that is in close contact with the inner peripheral surface of the wire accommodation portion in the wire accommodation portion.

A mat seal for an electrical connector includes a plurality of through-holes extending in a through-hole direction through the mat seal, a grid of a first material having a plurality of grid meshes, the grid is arranged with the through-holes extending through the grid meshes, a first material layer of a second material disposed on a first side of the grid, and a second material layer of a third material disposed on a second side of the grid opposite the first side. The first material of the grid has a greater compression modulus than the second material of the first material layer and the third material of the second material layer.

A packaging apparatus, comprising: a top configured for receipt of a payload therein and including a lip around a perimeter of top; and, a bottom configured for receipt of the payload therein and formed as a counterpart to the top, wherein the top and bottom are formed from the same mould and are identical but for the lip which is not included in the bottom.

A multilayer tape assembly is described which can be used with insulation jacketing and particularly for self-sealing lap (SSL) applications. The tape assembly includes two adhesive layers with associated carrier and release layers in conjunction with a differential release system. Various methods of use are also described, including a method of forming a securable insulation jacket.

A method for producing a sealing element for forming a seal on a vehicle body, in particular a vehicle door; in the method, a profiled strip section is subjected to punching, and/or an additional element portion of the sealing element is molded onto a profited strip section. The profiled strip section is provided with a projection that extends transversely to the longitudinal direction of the strip, and the projection is used for positioning the profiled strip section relative to a punching die or injection mold in the longitudinal direction of the strip.

A component on a composite bridge plug used for plugging a wellbore includes a first member including a wound composite material, and a second member including a molded fiber phenolic composite material. The wound composite material of the first member makes up more than half of a volume of the component. The first member is a convolute-wound core having a cylindrical shape. The second member forms an outer shell that is molded over an outer surface of the first member. The component is a cone of the composite bridge plug.

A sealing structure for a front cover of an engine includes a front cover made of resin of an engine in which a through-hole, into which a boss part of a torsional damper is to be inserted, is provided, and a sealing apparatus to seal between the through-hole of the front cover and the shaft part. The sealing apparatus includes a support ring that is made of resin and has an annular shape, and an elastic body part that is made of an elastic material, has an annular shape and is attached to the support ring. The elastic body part has an annular seal lip that contacts the shaft part such that the shaft part is able to slide, and the support ring is bonded to the front cover.

A multilayer tape assembly is described which can be used with insulation jacketing and particularly for self sealing lap (SSL) applications. The tape assembly includes two adhesive layers with associated carrier and release layers in conjunction with a differential release system. Various methods of use are also described.

A transfer system which can be used in a flexible manner for transporting or processing, respectively, profiles, in which the injection device comprises a mold for receiving the profile during the injection, wherein the mold has at least two contour parts and the injection device has a closing unit for opening/closing the contour parts, wherein the closing unit is configured for keeping the contour parts open until the profile is enclosed by the contour parts, and wherein the transportation device is configured for moving, preferably not rotating, the profile exclusively parallel to the transportation path, wherein the closing unit and the injection device are assembled so as to be displaceable conjointly with the first feed table, and the first feed table in the direction of the transportation path is displaceable so far until the contour parts enclose the profile.
