A method for brazing a metallic honeycomb body () for exhaust gas treatment, includes at least:

Method for brazing a metallic honeycomb body for exhaust gas treatment and apparatus for carrying out the method

A plunger is used for applying an adhesive to a honeycomb structure. The plunger includes a receptacle, a plunger covering, a metering unit and a chamber. The chamber being delimited by the receptacle and the metering unit and the plunger covering is located on a side of the metering unit facing away from the chamber. The plunger is used in conjunction with a device for applying an adhesive to a honeycomb structure, in particular a metal catalyst support for purifying the exhaust gas of mobile internal combustion engines.

Method and device for applying glue to a honeycomb structure

A process and an apparatus for applying a brazing material to a metallic structure, especially a honeycomb body, include bringing the metallic structure into contact with a pulverulent brazing material in such a way that the brazing material at least partially adheres to the metallic structure. The metallic structure and/or the brazing material are made to vibrate, at least when they are in contact.

Process and apparatus for applying brazing material to a metallic structure through the use of vibration

A method for manufacturing a metal structure in which the metal structure has separate walls forming channels through which a fluid can flow includes at least partially wetting the walls inside the channels with an adhesive, bringing the metal structure into contact with a solder that adheres to the adhesive, and carrying out a heat treatment to form soldered connections between the separate walls. The method is distinguished by the fact that the dosed delivery of the adhesive is performed by at least one dosing element having a honeycomb configuration and having an inlet side ( ) and an outlet side, the element being connected to the adhesive. The adhesive enters the dosing element through the inlet side and is uniformly distributed into the channels through the outlet side. The invention also includes a device for wetting the metal structure with the adhesive.

A method for producing a metallic honeycomb body, according to which at least partly structured metal sheet is coiled, laminated or looped to form a matrix. The matrix is oscillated by an external excitation and during or after the external excitation is introduced into a casing tube.

Method and device for producing a metallic honeycomb body

A process and a device are provided for manufacturing a honeycomb body from at least one metal foil constructed from at least two different layers, in particular from steel roll-bonded with aluminum. The metal foil is at least partly provided with a structure through the use of shaping, and is then layered or laminated or wound into honeycomb body. The metal foil is heat-treated with resistance heat generated within the foil before shaping. The heating is preferably carried out through the use of induction coils. In this way the capacity for cold shaping is increased and where required an oxide layer can be produced in a defined atmosphere. The invention reduces the energy and apparatus costs and permits economical manufacture of high-quality honeycomb bodies, in particular with microstructures increasing effectiveness.

Process for manufacturing a honeycomb body from heat-treated two-layered or multi-layered metal foils

The invention relates to a roll manufactured with a light waveguide conductor (LWG-conductor), in particular for the transmission of optical signals from and to, respectively, a moving body. A perfect winding construction from which the conductor can be unreeled without interference is obtained in that the LWG-conductor (1) is wound to form a self-supporting cross-roll without a winding core.

Roll manufactured with a light waveguide conductor

The invention relates to a turbomolecular vacuum pump (1) with a rotor (6) and at least one antifriction bearing (17) for the rotor, the stationary ring (19) of the antifriction bearing being seated on the wall of a sleeve (21) which in turn is supported through at least two O-rings (26, 27) made from an elastic material on a casing section (13) of the pump. To improve the heat flow from the sleeve (21) to the casing (13) of the pump, the annular space (29) formed by two seal rings (26, 27), the sleeve (21) and the pump casing (13) is filled with a medium (31) promoting heat flow from the sleeve to the adjacent part of the casing.
