摘要： A trapezoidal endless power transmission belt structure is provided which is made primarily of elastomeric material and has a pair of oppositely arranged surfaces disposed in spaced relation to define an outside and inside surface of the belt structure and has a load-carrying section arranged midway between the inside and outside surfaces. The belt structure has a tension section and a compression section which are of similar construction and each is comprised of a plurality of layers including a fiber-loaded layer disposed adjacent the load-carrying section and a fabric layer disposed remote from the load-carrying section; and, the fabric layers and fiber-loaded layers cooperate to assure that the belt structure has longitudinal flexibility yet has transverse rigidity or stiffness sufficient to enable the belt structure to be operated in associated sheaves free of shear planes parallel to the load-carrying section.

摘要： A gaseous carburetor or fuel control system includes a fuel metering assembly, a venturi mixer assembly, a throttle assembly, and an electronic control unit. The control unit controls the fuel metering assembly in a closed loop manner based on detected gas and air pressure to an air/fuel mixing venturi. An electronic governor which controls the throttle valve may also be controlled by the same control unit which controls the fuel metering assembly, using a separate control loop.

摘要： An emission control device for use with stationary or mobile gas-fueled internal combustion engines is described, which is placed in the fuel supply line and operates with full fuel authority. An oxygen sensor measures exhaust oxygen content. The valve internally houses a programmable microprocessor, a pressure transducer and a fuel flow conduit throttled by a balanced poppet valve. Signals to the microprocessor from the oxygen sensor, the pressure transducer indicating outflow gas pressure cause the microprocessor to motivate an actuator to move the valve within the gas stream and thus regulate the outlet pressure and also the gas flow rate to maintain a desired air/fuel ratio to the engine and keep exhaust emissions at an optimum level consistent with the engine operating load requirements and characteristics. Finite incremental control of valve position, preferably assisted by an internal position transducer, permits close control of the exhaust emissions.
