  • Patent number: 4413040
    Abstract: A metal halogen battery construction containing a novel reactor means having at least two reaction zones with a reaction initiator device in each zone, whereby the reactor permits controlled recombination of hydrogen gas and halogen gas in the system to form hydrogen halide, which is then dispersed into the aqueous electrolyte of the battery.

  • Patent number: 4371825
    Abstract: A method of minimizing the effect of parasitic currents in secondary batteries having a plurality of cells connected electrically in series and a common electrolyte in communication with the cells is described. Specifically, the parasitic currents flowing through the battery cause a cell imbalance over the charge/discharge cycle. This cell imbalance is minimized by first separating the cells of the battery into two equal groups. Then the battery is charged with the two groups of cells connected electrically in series, and subsequently discharged with the two groups of cells reconnected electrically in series in an inverted sequence.

  • Patent number: 4288507
    Abstract: Described is an electrode assembly comprising;a. a porous electrode having a first and second exterior face with a cavity formed in the interior between said exterior faces thereby having first and second interior faces positioned opposite the first and second exterior faces;b. a counter electrode positioned facing each of the first and second exterior faces of the porous electrode;c. means for passing an oxidant through said porous electrode; andd. screening means for blocking the interior face of the porous electrode a greater amount than the blocking of the respective exterior face of the porous electrode, thereby maintaining a differential of oxidant electrode surface between the interior face and the exterior face.The electrode assembly is useful in a metal, halogen, halogen hydrate electrical energy storage device.

  • Patent number: 4281455
    Abstract: The invention provides a razor assembly comprising a shaving unit and a handle. The shaving unit has a platform, a blade, pivotal mounting for pivotally connecting the shaving unit to the handle, and apparatus for receiving a biasing force from the handle. The handle includes two flexible arms which at one end have pivotal mounting apparatus complementary to the shaving unit's pivotal mounting apparatus, the flexible arms being secured to the handle in a region spaced from the handle's pivotal mounting apparatus. A movable button engages the flexible arms and is movable for flexing the arms to disengage the handle's pivotal mounting apparatus from the shaving unit's pivotal mounting apparatus and for reverse movement which frees the flexible arms for engagement of the handle's pivotal mounting apparatus with the shaving unit's pivotal mounting apparatus. The handle also includes apparatus for exerting a biasing force on the shaving unit's apparatus for receiving a biasing force.

  • Patent number: 4273839
    Abstract: Described is a method of activating a carbonaceous electrode comprising the steps;1. Providing a negative electrode and a carbonaceous positive electrode spaced apart from each other;2. Providing an aqueous electrolyte with a current carrying water soluble material therein; and3. Closing the circuit and passing a current between the positive and negative electrodes through the electrolyte thereby generating oxygen for a period of time sufficient to activate the positive electrode.The electrodes are useful in a metal halogen electrical energy storage device.

  • Patent number: 4146680
    Abstract: A zinc-chlorine battery system in which chlorine gas evolved from the cell structure of the battery during charging of the battery is combined with a stored supply of water to form solid chlorine hydrate. During the discharge cycle of the battery, the chlorine hydrate is decomposed to replenish the chlorine content of the electrolyte.

  • Patent number: 4100332
    Abstract: A bipolar electrode element has an electrically conductive, chemically inert, generally flat wall having first and second opposing faces, each of the first and second faces having a plurality of spaced, parallel grooves therein with the spaced grooves in the first face being laterally staggered from the spaced grooves in the second face, first and second spaced and substantially parallel electrodes having first edges disposed within first and second respective grooves of said spaced parallel grooves in said first face and extending generally perpendicular from the plane of the inert wall; and a third electrode having a first edge disposed within a groove in said second face and extending generally perpendicular from the plane of the inert wall. A battery stack is obtained by positioning a plurality of the bipolar battery elements such that their electrodes are interdigitated.
