Abstract: There is disclosed an electrode construction of the type including a terminal arrangement and support structure for said terminal arrangement, said support structure adapted for the transcutaneous application of the electrode to a patient. The support structure may be fabricated from a layer of foam or microporous material, or plural layer employing a combination of both, or from a layer of conductive adhesive. The terminal arrangement may be of single terminal or multi-terminal design, and is provided by a conductive pattern printed on a semi-flexible plastic-like sheet, wherein said pattern is printed with a conductive ink of the type employing a conductive metal, such as silver, in a binder composition. The disclosure also contemplates novel structure for connection of the electrode to a lead wire, as well as several novel, overall designs for the construction of the electrode support means.

Abstract: A device for measuring the depth and temperature of a liquid stored in a tank is provided. The device includes a hermetically sealed vertically disposed tube having ultrasonic transmitter/receiver devices at either end thereof with a reflector vertically movable in the tube and having a through-hole therein permitting transmission from one end of the tube to the other as well as reflection. A float encircles the tube and moves up and down with the level of liquid in the storage tank. The float and reflector are magnetically interconnected so that the reflector moves up and down with the float.
