Title: Metallic paintwork - built up using surface hardened resin stages to eliminate intermediate stoving
Inventor: LEICHT ERHARD DR DIPL CHEM
IPC: B05D5/06
Filed: 1972-02-15
Abstract: Coatings for metallic surfaces applied in two principal stabes, one coating which acts as a primer, an undercoat and/or a texturising paint, and which incorporates metallic pigments, and a protective transparent varnish or resin cured by a stoving treatment. The interfaces between successive layers and coatings are partially hardened. Specif. claims coatings incorporating finely divided Al particles and epoxy resins as the binder resin in the pigmented coating. Resins cured by electron beams or UV radiation are preferred. Pref. the resins and pigments are applied as mixed finely divided powder paints by e.g. fluidized bed or electrostatic spraying techniques rather than as liq. suspensions. Text refers particularly to use for paint requirements for automobile bodies. Use of successive layers applied using resin binders which can be rapidly surface hardened to accept subsequent coatings without significant interchange of material enables the conventional intermediate stoving treatments to be eliminated. Text indicates a preference for use of epoxy resins as unsaturated ester derivs., esp. copolymers which can be cross-linked by activation by radiation wavelengths of 100-700, pref. 250-450 micrometres to generate sufficient surface hardness at doses of 0.25-2 M rad, possible at radiation scan rates of up to 100 m/min to produce firm skins.

Title: Evaporative type room humidifier - is controlled by humidistat inside special inlet air chamber in humidifier
Inventor: BRUNE PIT JUERGEN
IPC: F24F6/04
Filed: 1973-12-05
Abstract: The humidifier has a casing the lower part of which forms a water reservoir.
