摘要： A pneumatic compressor capable of supplying compressed gas to a pneumatic tool. The compressor can be powered alternatively by either a battery or an AC power source. The compressor comprises a permanent magnet DC electric motor and circuitry for converting the AC power source to DC power. The compressor includes a receptacle for accommodating one or more of a plurality of batteries and includes circuitry for using batteries having different voltages. The AC power source may also be used to charge a battery connected to the compressor.

摘要： A test circuit determines state of an electrical element supplied with alternating current and measures the duration of that state. The test circuit is connected to the element so that current flows to the test circuit when the element is in the state being measured. The test circuit rectifies the alternating current to periodic pulses, which are counted to determine the duration of the current and, thus, the state. The circuit is particularly useful for testing operation of a dishwasher pump motor that is interrupted periodically. The test circuit is connected to auxiliary contacts that open and close in correspondence with the operation of the pump motor.
