专利汇可以提供Deferred-action electrochemical generators专利检索,专利查询,专利分析的服务。并且Deferred-action electrochemical cells or generators wherein the electrolyte in a reservoir and electrodes in a container are maintained separately sealed off from each other by frangible membranes that can be ruptured by appropriate priming devices for activation of the cell or generator by flow of electrolyte from the reservoir into the container. In case of electrodes of lithium these must be maintained in an inert or neutral gas in the sealed container to prevent their alteration or deterioration during storage. Upon priming or breaking of the frangible membranes electrolyte flows from the reservoir into the container and simultaneously the neutral or inert gas is driven out of the electrode container and is directed via a conduit into the electrolyte reservoir wherein it is retained. A closed system is thus provided wherein neither electrolyte or inert gas can escape to the surrounding environment. Preferably, the reservoir and containers are enclosed in an overall fluidtight enclosure. Thus, spillage of electrolyte from the primed cell or generator upon vibration, irregular movements or overturning of the primed cell or generator and its loss to environment is avoided, as is damage from spilled electrolyte. At the same time, operation of the cell or generator continues undisturbed.,下面是Deferred-action electrochemical generators专利的具体信息内容。

  • 2. Deferred-action electrochemical generator according to claim 1 including a sealed enclosure means surrounding the container and reservoir.
  • 3. Deferred-action electrochemical generator according to claim 1 including a plurality of said containers each enclosing electrodes and wherein said reservoir containing primary fluid including manifold means is connected to distribute said priming fluid to all of said containers from said reservoir upon operation of said priming means.
  • 4. Deferred-action electrochemical generator according to claim 1 including a sealed enclosure means surrounding said container and reservoir, said priming means comprising an operating member located externally of said enclosure means, a pivoted lever internally of said enclosure, a tubular plunger movable by said pivoted lever to effect rupture of said frangible partition means, and a movable perforate tube engageable by said tubular plunger and movable during such engagement to rupture said frangible membrane means whereby operation of said operating member successively ruptures said frangible partition means and said frangible membrane means thus permitting said flow of gas into said reservoir via said conduit means and said flow of priming fluid into said container via said duct means.
  • 5. Deferred-action electrochemical generator according to claim 4 including means to prevent accidental rupturing motion of said movable perforate tube and also accidental rupturing movement of said tubular plunger.
  • 6. Deferred-action electrochemical generator according to claim 4 including means to seal said tubular plunger against leakage.
  • 7. Deferred-action electrochemical generator according to claim 1 wherein said reservoir includes a distributor having therein a duct which said frangible membrane means spans to prevent flow of said priming fluid into said container until rupture of said frangible membrane means is effected, and said reservoir also includes a coupling means at its upper end to which said conduit means is connected, said coupling means being closed off by said frangible partition means in the unruptured condition via said conduit means into said reservoir until rupture of said frangible partition means is effected.
  • 8. Deferred-action electrochemical generator according to claim 7 including a tubular plunger member mounted slidably in said coupling means for movement therein to rupture said frangible partition means upon operation of said priming means, to permit flow of gas from said conduit means into said reservoir.
  • 9. Deferred-action electrochemical generator according to claim 7 including a sealing ring member on said coupling means and plugging means on the upper end of said tubular plunger that sealingly engages said sealing ring member when priming movement of said tubular plunger is effected.
  • 10. Deferred-action electrochemical generator according to claim 9 wherein said tubular plunger has an aperture movable from a closing off position to a registering position relative to said conduit means on operation of said priming means.
  • 11. Deferred-action electrochemical generator according to claim 1 wherein said electrodes in said container are respectively lithium for negative electrode and cuprous chloride containing positive electrodes, said priming fluid is a nonaqueous electrolyte and said neutral gas is argon.
  • 12. Deferred-action electrochemical generator according to claim 11 wherein said nonaqueous electrolyte is lithium tetrachloroaluminate dissolved in methylchloroformiate.
