This invention relates to a continuous ultrasonic washing method and apparatus for small parts in manufacture. It more particularly relates to washing small manufacture parts in an apparatus requiring small volumes of water, no cleaning detergents, and an efficient ultrasonic transducer system where the ratio of ultrasonic power per volume of water is at a level well above that for other ultrasonic washers in use today.

A modular power outlet system employing a starter module for connection to a source of electrical power, an outlet strip module containing a plurality of power outlets, an inline passthrough coupler module for electrically connecting two or more outlet strip modules, and an inline crossover module for switching circuits to which power outlets are connected, and an end cap module for terminating an outlet strip module is disclosed herein. In a single circuit embodiment of the system, each power outlet is connected from the same electrical circuit. In a first two circuit embodiment of the system, power outlets in an outlet strip module alternate between the two circuits. A plurality of outlet strip modules can then be electrically connected using an inline passthrough coupler module. In a second two circuit embodiment of the system, each power outlet in an outlet strip module is connected to the same electrical circuit. One end of the outlet strip module is electrically connected to a two circuit starter module and the other end is electrically connected to one end of an inline crossover coupler module. A second outlet strip module is then electrically connected to the other end of the crossover module which switches the electrical circuit to which the second outlet strip module is connected. Outlet strip modules and crossover coupler modules can be successively electrically connected in this manner so as to result in a series of outlet strip modules which alternate between electrical circuits.

A method for providing a real time measurement of the purity of one gas in a binary mixture of two known gases applies principles of the fan laws and ideal gas laws in a manner whereby the volume percent purity of the gas may be calculated directly from measured fan differential pressure. The calculated purity is preferably corrected for variations in temperature and pressure. The method requires the determination and use of an appropriate fan constant based on the gas whose purity is to be measured and specific to the fan being used to circulate the gas mixture and the speed at which it operates. An appropriate adjustment factor for differences between design and measured speed may also be applied in accordance with the fan laws. The method can provide real time measurement of hydrogen gas purity in the cooling gas circulated inside a large synchronous AC generator and utilizing a microprocessor to provide a real time output of hydrogen gas purity.

A method for providing a real time measurement of the purity of one gas in a binary mixture of two known gases, which mixture also contains water vapor, applies principles of the fan laws and ideal gas laws in a manner whereby the volume percent purity of the gas may be calculated directly from measured fan differential pressure. The calculted purity is preferably corrected for variations in temperature and pressure. The method requires the determination and use of an appropriate fan constant based on the gas whose purity is to be measured and specific to the fan being used to circulate the gas mixture and the speed at which it operates. An appropriate adjustment factor for differences between design and measured speed may also be applied in acordance with the fan laws. The method is particularly well adapted to provide real time measurement of hydrogen gas purity in the cooling gas circulated inside a large synchronous AC generator and utilizing a microprocessor to provide a real time output of hydrogen gas purity. The principles underlying the method of the invention are also utilized to develop a correction factor to convert hydrogen purity measured from a dry gas mixture sample using a thermal gas analyzer to a true hydrogen purity. The method may further to applied to calculate actual water vapor content in a sample from which hydrogen purity was measured by a thermal gas analyzer.
