of a catalyst converter provided in an exhaust gas passage, an air-fuel ratio correction amount is remarkably changed when the output of the upstream-side air-fuel ratio sensor is switched from the lean side to the rich side or vice versa, and the actual air-fuel ratio is adjusted in accordance with the air-fuel ratio correction amount. The remarkable-change speed of the air-fuel ratio correction amount is changed in accordance with the output of the downstreamside air-fuel ratio sensor.

and movable contact member are freely turnable with respect to one another, and have cooperable engaging portions for causing the movable contact member to pivot in response to movement of the float member. The fixed contact member has contact portions disposed annularly for engagement by the movable contact member in response to its pivotal movement irrespective of the angular orientation of the float housing. Engagement of the contact members controls a circuit from the fixed contact member to the bearing.

4693119 LITHIUM BATTERY ENERGY MONITOR Leopold J Johnson assigned to The United States of America as represented by the Secretary of the Navy A lithium battery is provided with an energy monitor that continuously indicates the energy remaining in the battery. An electrolytic coulometer is Connected in series with the battery and has a cantilevered cathode which increases its mass in proportion to the total amount o f current that flows from the battery. Since the mass of the cathode and hence its resonant frequency changes in proportion to the total current, a mechanical transducer in contact with the electrolytic coulometer causes the cantilevered cathode to resonate at different frequencies which is monitored to provide a continuous reading of remaining battery energy.

4694128 FLOAT SWITCH CONSTRUCTION ' FOR MONITORING LIQUID LEVELS Peter Lupoli, Donald Mattis assigned to Casco Products Corporation A float switch construction for monitoring liquid levels, comprising a float housing having a float member which is movable therein between raised and lowered positions. In the housing there is a fixed contact member and an asymmetric, elongate movable contact member, the latter having a laterally offset portion constituting a gravity-responsive mass. The housing has an electrically conductive bearing which mounts the movable contact member for both turning and pivotal movement and for conducting current to or from it. The float member

4694173 N O N D I S P E R S I V E GAS ANALYZER HAVING NO MOVING PARTS Jacob Wong assigned to Hibshman Corporation A multi-component non-dispersive gas analyzer o f a type typically used to measure the concentrations o f gases present in automotive emissions and in breath analyzers has no moving parts and employs electrically operated means for effectively inserting and removing a reference cell from the optical path and for selecting a particular filter to determine momentarily the wavelengths o f radiation being examined. The means for accomplishing these ends include a substrate on which a layer of vanadium dioxide is deposited. The layer is a good reflector at temperatures greater than 67£20 + 0 C. and reflects only slightly at lower temperatures. The layer is alternately heated by an electrical current and is then allowed to cool to provide the desired optical switching action. This electricallycontrolled selectively reflective layer is then used in conjunction with the reference cell and with an array of filters to implement the necessary switching and selection of the components.
