Abstract: A device for tempering and homogenizing viscous masses, particularly putty, and incorporating a combined heat exchanger and homogenizer (10), having a tubular part (12) through which the putty under pressure and tempering is caused to pass. In said tubular part (12) is provided a guiding device (16) designed compulsory to give the putty a plurality of direction changes relative to the tubular part (12). The guiding device (16) incorporates at least a first helical heat exchanger tube (17) arranged around a centrally disposed, second heat exchanger tube (18).

Abstract: A method for supplying an electrically conductive, floating medium, e.g. paint, from a storage system (11) via a feed conduit to a consumption station (12) in which is incorporated an electrostatically chargeable distribution device (29), e.g. a paint spraying gun, for treatment, e.g. painting of treatment units, whereby the medium is supplied to an intermediate storage forming part of the feed conduit between the consumption station and the storage system, and which feed conduit is adapted to be interrupted electrically and physically between the storage system and the intermediate storage by an interruption unit. The purpose is to prevent the electrostatic charge in the spraying nozzle from being transferred to the storage system of the painting plant.
