Wayne H. Barber has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Electropneumatic brake valve with release and running modes
    Patent number: 6238010
    Abstract: An electropneumatic brake controller of the present invention including a main reservoir, pneumatic brake pipe relay and first and second restrictions connected in series with the main reservoir, the brake pipe relay and brake pipe and first electropneumatic valve connected in parallel to the second restriction. The second restriction is smaller than the first restriction. The first electropneumatic valve is responsive to an electric release signal to cut out the second restriction. When the two restrictions are in series, this is the running mode whereas when the second restriction is cut out, this is the release mode. A control unit controls the electropneumatic valves to produce an overcharge cycle in response to a release brake signal. This cycle includes overcharging the brake pipe, holding the overcharged condition for a fixed period of time and bleeding to a normal release brake pipe pressure.
