Systems and methods for improving adhesion of an insulating foam to a molded polymeric insulating structure through use of ozone gas for functionalization of molded polymeric surfaces of an internal cavity of the insulating structure.

The invention relates to a method for manufacturing a hoisting rope, comprising the steps of providing a plurality of elongated composite members, which composite members are made of composite material comprising reinforcing fibers in polymer matrix; and arranging the composite members to form an elongated row of parallel composite members, which row has a longitudingal direction, a thickness direction and a width direction, and in which row the composite members are positioned side by side such that they are parallel to each other, and spaced apart from each other in width direction of the row; and directing plasma treatment on the outer surface of the composite members; and embedding the composite members in fluid polymer material; and solidifying the polymer material wherein the composite members are embedded. The invention relates also to a hoisting rope obtained with the method and an elevator comprising the hoisting rope.

A plug-in connector module for a modular industrial plug-in connector is provided, wherein the plug-in connector module has a housing with a housing surface, wherein the housing consists substantially of plastic, wherein the plug-in connector module has at least one electrical contact element, wherein the housing has at least one contact chamber with a contact chamber surface, wherein the at least one electrical contact element is arranged in the contact chamber, wherein at least a portion of the contact chamber surface and/or at least a portion of the housing surface are/is plasma-modified. A method for producing a plug-in connector module of an industrial plug-in connector is also provided and includes: producing a plastics housing with a housing surface and at least one contact chamber for receiving a contact element, modifying at least a portion of the housing surface and/or at least a portion of the contact chamber surface with an atmospheric pressure plasma with a working gas being fed in.

A system is provided for generating plasma within narrow diameter tubes, e.g., tubes with an inner diameter of less than 1 millimeter. The system may comprise the tube, a nozzle connected to at least one end of the tube configured to supply a gas into the interior of the tube at atmospheric pressure, at least one ring-shaped anode electrode and configured to surround an outer surface of the tube, at least one ring-shaped cathode electrode spaced apart from the anode electrode along the longitudinal axis and configured to surround the outer surface of the tube, and a voltage source connected to the at least one anode electrode. When activated, the system is configured to generate an electric field between the electrodes which ignites a plasma within the gas in the interior of the tube.
