  • Patent number: 4108008
    Abstract: Connection is quickly made to a plurality of fluid lines, the pressure or other non-flow characteristic of which is desired to be measured, by means of a vehicle mounted port block container valved access to a plurality of vehicle fluid lines and a matching transducer block having a corresponding plurality of transducer retaining bores correspondingly aligned for close fluid communication with one of the ports, each containing a pusher to open the valve of the related port and each containing a fluid-to-electric parameter transducer for measuring a parameter of fluid in a corresponding port, there being an electrical interconnection means, such as a cable, for carrying conductors to the transducers. A locking means provides for snugging the transducer block tightly against the port block and for locking the blocks together by two independent motions of a locking handle.

  • Patent number: 3973848
    Abstract: The contaminants in the exhaust gas emissions from a motor vehicle such as carbon monoxide (CO) and hydrocarbons (HC) are analyzed and the concentration of the contaminants together with other pertinent data is displayed in a digital manner. The exhaust gas emissions are fed into a sample cell contained within a nondispersive infrared analyzer and the absorption of an infrared radiation beam at selected wavelengths by the gas within the cell is measured. A reference cell containing a reference gas is also positioned in the infrared radiation beam path. By means of a rotating chopper disk positioned in the light path, the infrared radiation beam passes alternately through the reference cell and the sample cell and is focused at a plurality of detectors which are each sensitized to a narrow wave band by a filter and which receive the alternate sample cell and reference cell radiation pulses.
