Method For Operating Electrochemical Detector Cell
US Patent:
4735691, Apr 5, 1988
Filed:
Dec 23, 1985
Appl. No.:
6/816648
Inventors:
Norman Green - Phoenix MD
Charles H. Ward - Baltimore MD
Charles H. Ward - Baltimore MD
Assignee:
Allied Corporation - Morristown NJ
International Classification:
G01N 2746
US Classification:
204 1T
Abstract:
The method of operating a two electrode electrochemical detector cell in which the cell is connected to an external current measurement circuit through a cyclically operated switch which alternately opens and closes the connection between the cell and the external circuit. The cell is operated without bias potential. The peak current obtained from the cell after closing the connection to the external circuit may be measured immediately without any delay for transient current to decay. Means are disclosed for automatically compensating for background current error in the cell current measurement.
Six-Cycle Engine
US Patent:
4289097, Sep 15, 1981
Filed:
Nov 13, 1979
Appl. No.:
6/094040
Inventors:
Charles P. Ward - Arbutus MD
International Classification:
F02B 1902, F02B 7502
US Classification:
123292
Abstract:
The invention is an improved six-cycle engine that improves performance in fuel economy and in the power to size ratio. The six cycles are a first intake stroke, a compression and storing stroke, second intake stroke, a compression and combining stroke, the power stroke, and the exhaust stroke. The invention provides for using some of the fuel's energy that ordinarily is lost in the engine's cooling system, by absorbing heat after the first stroke and subsequently using it in the power stroke. A special configuration of a separate chamber for the compression of gases induced in the first intake stroke and a special configuration for the valve to that chamber are part of the design. Two induction cycles are included in the six cycles for each power stroke.
