The present disclosure relates to a casting device for producing a potting for a gas exchanger and a method for producing such a potting. Accordingly, a casting device is proposed for producing a potting for a gas exchanger under the influence of a centrifugal force, comprising a distributor comprising an opening and at least one continuous channel and adapted to receive a fluid potting material via the opening and to guide it via the at least one channel. The casting device further comprises a cassette defining an inner cavity for receiving gas exchanger elements and which is fluidly connected to the at least one channel. The distributor comprises at least two distributor components which, in the assembled state of the distributor, define the opening, are connected to one another in a leak-proof manner, and form the at least one channel between adjacent regions.

A pressure-sensitive adhesive tape for molding a plastic lens having a substrate and a pressure-sensitive adhesive layer formed on a surface of the substrate. The pressure-sensitive adhesive layer includes an acrylic copolymer having a functional group and a crosslinking agent capable of reacting with the functional group; the acrylic copolymer has a weight-average molecular weight (M.sub.w) of 1,100,000 or more and a molecular-weight polydispersity (M.sub.w/M.sub.n) of 10.0 or less; the pressure-sensitive adhesive layer has an elution percentage of 48.0% or less when immersed for two hours in toluene the temperature of which being adjusted to 80° C.; the pressure-sensitive adhesive tape exhibits a shift length of 0.15 mm or more and 0.50 mm or less after 800 minutes in a creep test; and the plastic lens has a refractive index of 1.59 or more.

The invention relates to a construction chamber (1) for an apparatus for additive manufacturing of three-dimensional objects, comprising a construction chamber base body (2) which limits a construction volume (4) forming a construction room (3), wherein the construction chamber base body (2) is formed segmented in several construction chamber base body segments (2a, 2b) that can be attached or are attached to each other forming the construction chamber base body (2).

The present invention relates to a process to reduce internal stresses in insulation molded onto complex pipes, preferably complex subsea pipe, to reduce cracking in the molded insulation. Insulation materials applies to complex pipes comprising branches, i.e., valves, and the like, may be susceptible to cracking at, or near where the branch connects to the pipe as the coating of insulation material cures or hardens. The process of the present invention aims to reduce post molded cracking by reducing molded in stress at the branch/pipe junction. This is accomplished by providing a preform at or near a branch/pipe junction prior to applying the coating of insulation material.
