A converter unit includes: a housing with a moulded-on hollow cylinder that extends into the housing; a non-magnetic toroidal core supporting a first secondary winding, contacting the housing bottom concentrically with the hollow cylinder and is embedded in a solid compound; a magnetic toroidal core supporting a second secondary winding, arranged concentrically with the hollow cylinder above the non-magnetic toroidal coil; and a casting compound with which the housing opening is closed. To achieve a compact converter unit, a first planar spacing element is arranged between the first and the second secondary windings, directly contacting the first secondary winding and the second secondary winding. In addition, electrically insulating particles fill out the space between the second secondary winding and the housing wall, and the casting compound extends at least up to the particles, which lie at the top towards the housing opening.

Temperature stability at the temperatures prevailing in a motor and stability that is required over an entire temperature range are provided by an attenuating mass. This enables continuous use at temperatures of approximately 150&#xb0; C. while providing ultrasonic attenuation at low temperatures.

Encapsulating a component structure includes applying a fluid, light-sensitive first reactive resin layer to a surface of a component substrate containing the component structure, exposing and developing the first reactive resin layer so as to form a frame structure that encloses the component structure, covering the frame structure with an auxiliary foil, applying a second reactive resin layer to a surface of the auxiliary foil so as to form ceiling structures on the surface of the auxiliary foil, at least one of the ceiling structures making a seal with the frame structure, and removing the auxiliary foil in areas between ceiling structures.

A process is provided for the catalytic removal of polycyclic aromatic nitro, nitroso and/or amino compounds from the exhaust gas of a combustion system, in particular a diesel engine. The exhaust gas is brought into contact with a catalytic converter which includes a catalytically active material that contains titanium dioxide, at a temperature of from 150 to 600&deg; C. The polycyclic aromatic compounds are oxidized at the catalytic converter through the use of oxygen to form nitrogen oxides, carbon dioxide and water.

Halogen-free epoxy resins that arise from the addition of an epoxy component to a phenol component with base catalysis are disclosed, whereby the molar mass can be adjusted by means of the molar ratios of the initial materials. The resulting resins can be used in the field of electronics, both as molding compounds and as circuit board materials and adhesives.
