Publication number: 20160018130Abstract: Known chimneys or chimney furnaces use flue gas flow units for heating buildings, said devices having displaceable or fixed obstacles for deflecting flue gas for generating flue gas turbulence. The invention relates to a device and method for transferring heat through a flue gas discharge pipe in which pivotal guide plates are inserted in the longitudinal direction of the pipe run, at which the flue gas flow is more or less deflected in a sinuous line as function of the pivot angle of the guide plates that can be adjusted during furnace operation. A fan can increase the flue gas flow. An optional furnace heat exchanger generates additional hot water as needed. The controller activates the actuators for the fan, guide plate pivot angle setting, and at least one circulating pump as a function of the prescribed controlled variables such as flue gas temperature, reservoir temperature, heat exchanger performance, or flue gas flow.Type: ApplicationFiled: September 14, 2015Publication date: January 21, 2016Inventor: Klaus Schmitt

Patent number: 8246054Abstract: The present invention relates to cylinder head gaskets on internal combustion engines, with at least three layers, namely a mid-layer, a function layer and a layer of a compression limiter. The mid-layer is arranged between the function layer and the compression limiter. The mid-layer has at least two essentially round fixing openings, outside a sealing region. The compression limiter is beaded around the edges of the fixing openings in the region thereof, and in this way fixes the compression limiter to the mid-layer.
