  • Exhaust system having variable exhaust gas paths
    Patent number: 10221737
    Abstract: An exhaust system for internal combustion engines has an exhaust tract, which has at least one first flow path and a second flow path for an exhaust gas stream. The first and the second flow path extend fluidically separated from each other from a pre-silencer to at least one end silencer. Depending on the rotational speed of the engine, the first flow path can be continuously closed by way of a controllable flap, wherein the exhaust gas stream is guided through the second flow path when the flap is closed.
    Type: Grant

  • Method of extracting human saliva
    Patent number: 4774962
    Abstract: In a method of extracting human saliva a resilient absorbent inert body is chewed by a person and is subsequently introduced into a centrifuge tubule (11) provided with an apertured floor (13). The centrifuge tubule (11) is introduced into a centrifuge and subjected to a spinning process, whereupon the saliva is pressed out of the resilient body (12) and passes through the floor (13) into the lower part of the centrifuge tubule (11).
