  • Method of reducing NOemissions in rotary preheater mineral kilns
    Patent number: 7377773
    Abstract: This invention relates to a method to further enhance NOx reduction in rotary preheater mineral kilns by coupling the temperature control and gas composition uniformity afforded by the high temperature mixing with the use of chemical reducing agents. The chemical reducing agent or agents, generally chosen from ammonia or ammonia precursors, are introduced at a specific point in the rotary preheater kiln which has as an optimal temperature window to achieve the greatest reduction of NOx emissions.

  • Spring support arrangement
    Patent number: 6199845
    Abstract: In a spring support for a suspension strut of a motor vehicle, a spring collar is provided for supporting a coil spring. The spring support is connected in use with an outer tube of the spring strut. The spring collar comprises a pot-shaped receptacle for the outer tube of the spring strut. The collar is located eccentrically with respect to the outer tube and receptacle and has an annular spring coil support section located at an edge of the collar. This spring support section is connected with the pot-shaped receptacle by ribs that extend like the arms of a star toward the receptacle and have spaces between them. The spring support, including pot-shaped receptacle, ribs and annular spring coil support section, are formed as an integral cast part.

  • Arrangement for blocking a spring in a spring strut
    Patent number: 6186488
    Abstract: An arrangement is provided for blocking a spring in a spring strut of a motor vehicle. A spacer element for transporting a vehicle consists of at least one segment which can be snapped into the spring and is supported by a lower free end on a stationary spring plate of the spring strut.
