HEAT TREATED POLYMER POWDERS
The invention relates to heat treatment of polymorphic semicrystalline or crystallizable polymers to increase the content of the highest melting crystalline form. Such heat treatment results in a polymer powder that has a consistent, uniform melting range, improved flow and improved durability of the powder particle size for applications that require powder flow at elevated temperatures. In addition to improved powder properties, the articles produced from the powders also exhibit better physical properties in both appearance and in mechanical properties. Thus the invention also includes polymer powders and articles produced by the described processes.
ARTICLES OF COMPOSITE CONSTRUCTION AND METHODS OF MANUFACTURE THEREOF
An article manufactured in a mould and which comprises a structural composite of plastics layers, the article having a wall defining an internal space for holding contents therein; wherein, the wall is formed from at least two layers of plastics materials; wherein a first of said layers comprises a thermoplastics material and at least a second layer comprises a thermosetting resin and a fibrous layer.

Potting apparatus for a gas exchanger
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.
