Quadrupole gas analyzer comprising four flat plate electrodes

Abstract: WHERE K any value except 0125 < OR = K < OR = 0126 A further aspect of the invention relates to performance optimization of a quadrupole analyzer in the presence of relatively large amplitude, nonquadrupole field components A quadrupole analyzer wherein the trajectory stability of the charged particles is determined by two parameters a and q where

Distributorless ignition system interface for engine diagnostic testers

Abstract: An ignition system interface for interposing an automotive combustion engine having a computer controlled ignition with an engine test analyzer. The interface receives timing signals from the ignition computer and generates modified timing based on command from the engine analyzer. Modified timing signals are transmitted to the coil ignition module which fires the spark plugs of the engine. The analyzer may command a shorting of the cylinder which causes the interface to modify the timing at the appropriate time for inhibiting a selected cylinder from firing. Secondary signals from the spark plugs are received by the interface and converted to a proper voltage waveform for recognition by the engine analyzer. The cylinder No. 1 is monitored by the interface and converted to a proper waveform for transmission to the analyzer.

Peak characteristics and computers in continuous flow analysis.

Abstract: The data output of continuous-flow analyzers is examined, and the characteristics of sample peaks are related to the timing program of the sampler module. Optimal conditions are presented for continuous-flow analyzer performance and for computer acquisition of such data.
