Abstract: A method for making an antimicrobial composite film can include forming a first coating layer by applying a first coating material on a substrate and forming a second coating layer by applying a second coating material on the first coating layer. The first coating material can comprise a first resin. The second coating material can comprise an antimicrobial material in a second resin or a dispersion.

Abstract: A compact integrated waveguide load has a load section disposed within an interior region of the waveguide proximate to a closed end of the waveguide. The load section has a tubiform shape, with an exterior surface congruent with an interior surface of the waveguide and an interior surface defining a circumferential step within the waveguide. A method of making a compact integrated waveguide load includes providing a waveguide and placing electromagnetic wave absorbing materially circumferentially around the interior surface to create an inward step.

Abstract: There is described a suspension arrangement (1) comprising a plate (2). The plate is provided with grooves (17) at the bottom of which there are holes (20) and may be used for supporting a shelf support holder (83). At the back side, the plate is provided with mounting fittings (22) that interact with vertical support members (21). The grooves communicate with holes (20) along part of their length, the holes opening at the back side. The suspension fittings may hereby be mounted so that they extend through a hole (20) and bears with a first support part against the back side of the plate (2) and a second support part that bears against the bottom of the groove (17). As the grooves (17) may be disposed with arbitrary spacing, it becomes possible to dispose suspension fitting with very great flexibility with regard to mutual spacing and level on the plate.
