Abstract: A lead-sulfuric acid storage battery in which one or both of the grids supporting the cathodic and anodic reactants comprises a base of stainless steel or titanium having a non-porous conductive coating thereover comprising a sulfuric acid resistant resin containing finely divided conductive particles, such as micronized graphite, the sulfuric acid electrolyte preferably containing a minor amount of titanyl sulfate.

Abstract: An indicator for measuring the liquid content of a container comprises an attitude compensating sensor including at least two variable resistor assemblies disposed within the container. The resistor assemblies are located at opposite ends of the container and are electrically connected to each other in series. Each resistor assembly comprises a resistor disposed within a housing and in communication with a movable wall of said housing located near its lower end. The housing resides in proximity to the bottom wall of the container and registers with the external ambient through an opening provided in one wall thereof. The total resistance developed by the sensor comprises the sum of the resistances of the individual resistors, and remains constant for a particular quantity of liquid regardless of the distribution of the liquid within the container.

Abstract: A liquid container is provided with paired variable resistors fluidly connected to the container at opposite ends of the bottom thereof. The resistors are electrically interconnected in series, and the output comprising the sum of the resistances is directly received by an electric current-responsive measuring device. Each of the resistors is weight-responsive and varies individually according to local liquid depth, however, the total resistance for a particular quantity of liquid in the container is always constant. The indicator of the present invention is particularly useful for measuring liquid content in containers subject to movement and change in attitude, such as, for example, gasoline tanks in motor vehicles.

Abstract: A lead-sulfuric acid storage battery in which one or both of the grids supporting the cathodic and anodic reactants comprises a base of iron, nickel or an alloy thereof, having a coating of tin-nickel alloy with a layer of lead thereover.

Abstract: Oxides of lead supported on a storage battery metal grid are cathodically reduced to lead in situ and are thereafter anodically converted to a pure form of lead peroxide of high electrical conductivity to serve as the cathodic reactant for lead-sulfuric acid storage batteries.

Abstract: A process for electroplating nickel on titanium which comprises connecting the titanium as the cathode in an acid solution to form a layer of titanium hydride on the titanium and thereafter immersing the hydrided titanium in a nickel plating solution and cathodically plating nickel thereover.

Abstract: A process for producing a high coulombic capacity nickel oxide cathodic reactant or depolarizer for primary electric cells. The process includes the steps of growing large nickel oxide dendrites on the exterior surface of a suitable base, converting the dendrites to a higher oxide of nickel, which is then removed from the base and ground to small particles for use as a cathodic reactant or depolarizer.

Abstract: The invention is a rechargeable voltaic cell in which both the cathodic and anodic reactants are derived from the electrolyte. The cell comprises an anode of lead mercury amalgam, an electrolyte of lead sulfamate and sulfamic acid and a cathodic reactant supported on a stainless steel base.
