摘要:
The invention relates to an insulation element, in particular for the acoustic insulation of an opening and/or of a cavity in a vehicle or building, having a carrier element and an expendable material. The carrier element has a plurality of through-holes, wherein only one surface of the carrier element is covered at least partially with expandable material, and the expandable material at least partially fills the through-holes. The invention relates furthermore to an insulation element produced therefrom, the use of the same and a method for the acoustic insulation and/or reinforcement of an opening or a cavity in a land, air or water vehicle or in a building.

Low-density thermoplastic expandable microspheres are disclosed. Various low-density structures, in particular, sandwich panels, based on foam prepared from the low-density microspheres, are also disclosed. Process of preparing low-density polymeric microspheres, per se, and the corresponding low-density structures, based on the microsphere foam, are also disclosed.

An intravenous delivery system may have a liquid source containing a liquid, tubing, and an anti-run-dry membrane positioned such that the liquid, flowing form the liquid source to the tubing, passes through the anti-run-dry membrane. The anti-run-dry membrane may be positioned within an exterior wall of a drip unit, and may be secured to a seat of the exterior wall by an attachment component. The attachment component may have various forms, such as a secondary exterior wall that cooperates with the exterior wall to define a drip chamber, a washer positioned such that the anti-run-dry membrane is between the washer and the seat, and an adhesive ring formed of a pressure sensitive adhesive and secured to the anti-run-dry membrane and the seat via compression. Interference features may protrude inward from the exterior wall or outward from the anti-run-dry membrane to help keep the anti-run-dry membrane in place.

A laminated structure has a first layer formed from a fiber reinforced plastic, a second layer formed from a fiber reinforced plastic and arranged opposed to the first layer, a first core layer formed from a first resin foam and arranged between the first layer and the second layer, and a second core layer formed from a second resin foam and arranged between the first core later and the second layer. The first resin foam has a higher flame resistance than the second resin foam. A laminated structure having flame resistance and high strength enough to endure a bird strike or the like at the same time can be manufactured at relatively low manufacturing cost.

摘要:
A substantially tubular reinforcing sleeve is disclosed and is designed for placing inside a coupling pipe in an assembly with the coupling pipe which forms part of a coupling. The sleeve is provided with a slit extending at least in axial direction of the reinforcing sleeve, and the slit is enclosed by slit edges of the reinforcing sleeve. The slit edges define an intermediate space which is variable in that the sleeve takes a flexible and resilient form. The dimensions and the form of the reinforcing sleeve are chosen such that the contour of the reinforcing sleeve can be placed inside a coupling pipe and there connects closely to an inner wall of the coupling pipe after placing. The reinforcing sleeve optionally includes toothings for fixation to the coupling pipe. A method is further disclosed for welding an outer end of a multilayer conduit to the above stated assembly.
