Abstract: An electrochemical cell comprising an anode, a cathode and a reference electrode operating in an aqueous electrolyte is utilized for detection of noxious gases in air. The gas is oxidized at the anode and detection thereof occurs as a result of the current generated by the reaction. A fixed potential difference is maintained between the anode and the reference electrode to avoid generation of undesired current from reactions involving an oxygen-water redox couple within the cell which would invalidate anode-cathode current for gas detection purposes. The fixed potential is chosen from within the range of about 0.9 to 1.5 volts.

Abstract: A device for the detection of and quantitative measurement of a gas in a given environment, such as alcohol in the breath or carbon monoxide in the atmosphere, is described. The device comprises intake and flow control means for the gas sample, and an electrochemical cell having an anode which provides a site for electrochemical reaction of the gas being detected, a cathode, a reference electrode, and an electrolyte in contact with the anode, cathode, and reference electrode. The anode, to ensure that the current production is a result of the gas being detected and not other gases, including oxygen, is maintained at a fixed potential in relation to the potential of the reference electrode. The device provides an accurate and inexpensive means of detecting and quantitatively measuring a gas contained in a given environment, i.e., alcohol in the breath of the subject being tested or carbon monoxide in the atmosphere.

Abstract: A machine has an intermittently rotating table for holding parts to be worked on or assembled. Operating units (20, 21, 25) are actuable either simultaneously for all units or groups of units, or independently of one another. The operating units can be mounted vertically over or under the table and also laterally and can receive the rotary movement of a central wheel or independent motors.

Abstract: An apparatus and method for high speed production of a multiple gauge metal strip product having a configuration with a transverse variable thickness are described. A milling machine cuts away at least approximately 75% of the total volume of metal to be removed from the surface of the initial strip of metal.

The shaving apparatus shaves off a maximum of about 25% of the total volume of metal to be removed from the surface of the milled strip in a single shaving pass to substantially form the desired configuration of the strip product.

After being plugged, each pipet is delivered from the rotary transport mechanism onto a collection apron. A multi-position stop element on the inclined pipet delivery rails of the machine allows pipets of varying diameters to be plugged with precision without requiring additional machine adjustments.

Abstract: A process is disclosed for fabricating semiconductor devices, and especially for fabricating semiconductor devices having multiple levels of metallization separated by polyimide or other organic materials. The process avoids the sputter etching and redeposition of the lower metal layer during reactive ion etching of openings through the organic layer. Sequential layers overlying the first layer of metallization include a layer of oxide, a layer of organic material, and a second layer of oxide. The second layer of oxide functions as a hard mask for patterning the organic material. The first layer of oxide acts as an etch stop and protective layer to prevent attack of the underlying metal during reactive ion etching of the organic layer. The first layer of oxide is of limited areal extent to avoid subsequent problems with the organic layer.

Abstract: A method of assembling an actuating lever (10) to a potentiometer (12) for use in electronic engine control systems for internal combustion engines as a throttle position sensor to generate electrical signals indicating the angular position (A.degree.) of the throttle blade. In such systems, there is usually one known or "home" position from which the position of the throttle blade is determined in order to determine the injection demands of the engine. The method herein is for accurately locating an actuating lever (10) to the moveable contact of the potentiometer (12) so that at the home position, the signal generated by the potentiometer is a known value. In addition, the potentiometer only needs to be adjusted on the throttle body once it is assembled thereto to account for throttle body tolerances, thereby satisfying rigid engine control requirements which require the positioning of the potentiometer to be accurately known.
