    摘要： An improved diagnostic meter, of the type used to measure the conduction of a vacuum tube in an audio power amplifier, which provides a display of the average value of instantaneous power dissipated by the tube. A probe containing a current sense resistor and a voltage attenuator interfaces between the tube and the amplifier to sample current through and voltage across the tube. A multiplier circuit computes a product of the sensed current and voltage, and a low-pass filter computes an average of the product. A display represents the average as a numerical value of Watts dissipated by the tube. A further improvement to the meter incorporates a DC-DC converter into the meter's power supply circuitry which allows the meter to be powered from the AC or DC filament supply provided by the amplifier.

    摘要： An engine includes a stationary member, a crankshaft supported for rotation by the stationary member, and a flywheel rotatable in response to rotation of the crankshaft. A fan has a plurality of fins and is rotatable in response to movement of the flywheel. A movable air vane includes a surface that deflects air from the fins as the fins move with the flywheel. The engine also includes an intake passageway for intake air and a throttle lever including a throttle pivot point and a throttle linkage aperture. The throttle linkage aperture and the throttle pivot point define a first axis having a first side and a second side. A throttle valve is disposed in the intake passageway to control the flow of intake air. The throttle valve is movable in response to movement of the throttle lever. A throttle linkage is positioned to directly or indirectly connect the air vane and the throttle lever. The throttle linkage and the movable air vane are disposed on the first side of the first axis. A resilient member is directly or indirectly connected to the stationary member and the throttle lever at a resilient member aperture that is located on the throttle lever on the second side of the first axis. The resilient member applies a force to bias the throttle lever in a first direction away from the flywheel.
