Abstract: A vehicle steering wheel includes an annular metal core with a molded plastic body and may include an outer molded layer of vinyl, wrap of leather or the like. A recess is provided extending along the inside rim of the wheel. An elastomeric cover, such as urethane rubber, covers the switch. Annular voids in the elastomeric cover may be selectively placed to provide the desired resilient characteristic. The strip switch preferably includes two outer strips and one inner strip of thin, flexible plastic. Electrically conductive, silver ink coatings are provided on the two outer strips facing each other to form strip contacts and having leads connected to the horn circuit. An inner strip or ribbon forms an insulator with openings to allow engagement of the two conductor strips under tactile pressure at any point around the rim. The inner ribbon is coated on both sides with adhesive to hold the strips together in an integral unit.

Abstract: HCN is removed from a gaseous stream, e.g., a synthesis gas stream, by a two stage procedure in which the gaseous stream is first contacted with a specified oxygenated reactant composition to remove the bulk of the HCN, and then the gaseous stream is contacted with a polysulfide solution to reduce further the HCN content of the stream.

Abstract: For road testing vehicle brakes the vehicle is equipped with transducers for measuring wheel speeds and temperatures, vehicle deceleration, brake line pressures, etc. A control circuit processes the transducer signals and supplies output signals proportional to the measured parameters as well as peak values generated during a brake test and hold values stored upon manual command. These various parameter values are displayed through a switching circuit on four numeric displays in view of the operator and a special bar graph display selectively displays parameters of prime interest to the operator such as front brake pressure or vehicle deceleration to produce a single blinking light when a selected target value is obtained and illuminates successive LED's in a lineal array each representing an increment of deviation from the target value so that the error appears in bar graph form for easy assimilation by the operator during the road test.

Abstract: A multiplex system is disclosed in which a plurality of auxiliary switches are mounted on a vehicle steering wheel and are selectively actuable to transmit predefined current levels through the horn relay circuit. The respective current levels are decoded and utilized to generate respective control signals.
