An electronic switch provided in the device transfers the connection in order that one in a pair thus transferred is grounded through a resistor having the characteristic impedance of the antenna plate while the other in the pair is connected to the receiver of the direction finder through a cable having the characteristic impedance.

Abstract: An electrochemical sensor capable of determining the partial pressure of various gases (e.g., CO, CO.sub.2, H.sub.2 S, alcohol vapors, hydrocarbons, NO.sub.x, etc.) and, optionally, substantially concurrently, but independently, oxygen content in gases and liquids. The sensor measures the amount of chemisorbent species formed either electrochemically by partial reduction (such as "Reduced-CO.sub.2 " in the case of CO.sub.2) or partial oxidation (in the case of alcohol) or non-electrochemically via specific adsorption (in the case of CO and hydrocarbons) on platinum or other metals. The charge required to oxidize this chemisorbed species is proportional to the amount of adsorbate on the electrode surface which is made a reproducible and reliable function of the partial pressure of the gas to be measured. By the proper selection of the sensor construction and electrical parameters, high sensitivity, fast response time, and high selectivity can be obtained.

The flat exterior bottom permits the wok to be seated on electrical heating surfaces for maximum heat transfer. The wok is also provided with a handle construction which includes a pair of oppositely directed handles integrally formed with the bowl-like utensil portion and extending outwardly and terminating in grip members formed of insulating material.
