A method for production of endless plastic hollow profiles, in particular tubes, comprises several production stages for the plastic tube and a coating stage for a metal coating. A reduced pressure is provided in the coating stage, whereby the metal is transferred into the gas phase and deposited on the tube as a surface layer homogeneously bonded thereto.

Method and device for production of endless plastic hollow profiles

A clamping joint (fitting) for pipes or hoses of a polymer material or a composite and having a base pipe made of polymer material. The joint includes a cylindrical support sleeve which is provided with several surrounding ribs and is defined by a collar on one end thereof. The collar includes a ring surface which is oriented towards the slip-on end and is situated in a level that is vertical in relation to the cylinder axis. A pipe or hose end having an enlarged cross-section can be slipped-on the remaining end (slip-on end) of the support sleeve. A clamping sleeve is slipped on the pipe or hose, can be displaced and is pushed over the slipped-on pipe or hose end for producing the connection. Webs having the same dimensions are formed to the ring surface. Each web is provided with a planar front face element that is parallel in relation to the ring surface. The front face elements of all the webs are located in a level that is in parallel in relation to the ring surface.

Clamping joint

A heat storage apparatus for a temperature range of about 10 to 95 degrees Celsius, especially for solar installations, heat pumps, boilers or the like and for extraction of heat for the operation of a room heating installation and/or an installation for water for use, consists of a low-temperature latent heat storage device and a downstream water reservoir. In that case, the fresh water feed for the installation for water for use runs, for preheating, through the low-temperature latent heat storage device before entry into the water reservoir and the return of the heat exchanger runs, for further cooling down of the return flow to the lowest possible temperature level, through the low-temperature latent heat storage device after exit from the water reservoir.
