Shock-resistant storage or electrolytic cells

Abstract

Abstract AN EFFECTIVE SHOCK AND VIBRATION RESISTANT ELECTRIC CELL INCLUDING A SPIRALLY WOUND ASSEMBLY OF ELECTRODES AND INTERPOSED SEPARATOR WITH PORTIONS OF THE OUTERMOST SPIRE OF ONE OF THE ELECTRODES JOINED BY WELDING TO THE INNER WALL OF A METALLIC CONTAINER TO IMMOBILIZE THE SPIRAL ASSEMBLY IN THE CONTAINER. THE SEPARATOR EDGES PROTRUDE BEYOND THE CORRESPONDING EDGES OF THE ELECTRODES. INTEGRAL TABS ARE PDROVIDED ON THE ELECTRODES, THE TABS OF ONE ELECTRODE BEING ELECTRICALLY JOINED AS BY WELDING TO THE BOTTOM OF THE CONTAINER AFTER PASSAGE THROUGH A SLOTTED INSULATING DISC LYING BETWEEN THE BOTTOM OF THE ASSEMBLY AND THE BOTTOM OF THE CONTAINER. THE INTEGRAL TABS OF THE OTHER ELECTRODE BEING ELECTRICALLY JOINED AS BY WELDING TO A CENTRALLY LOCATED CONTACT STUD AT THE UPPER END OF THE CONTAINER AFTER PASSAGE OF SAID LAST-NAMED TABS THROUGH A SLOTTED INSULATED MEMBER POSITIONED ABOVE THE SPIRAL ASSEMBLY. ANOTHER INSULATOR MEMBER LIES BETWEEN THE LATTER SLOTTED INSULATOR AND A SEALING COVER FOR THE UPPER END OF THE CONTAINER. A CENTRAL INSULATING ROD IN THE SPIRAL ASSEMBLY ABUTS THE UPPER AND LOWER SLOTTED INSULATORS AND AIDS IN PREVENTING AXIAL DISPLACEMENT OF THE SPIRAL ASSEMBLY BECAUSE OF THE ABUTMENTOF THE LOWER SLOTTED INSULATOR WITH THE BOTTOM OF THE CONTAINER AND THE ABUTMENT OF THE UPPER SLOTTED INSULATOR WITH THE INSULATOR MEMBER THAT ABUTS THE COVER. THE CONTACT STUD ALSO IS INSULATED FROM THE COVER BY ADDITIONAL INSULATION. THE COVER IS SEALED AS BY WELDING TO THE CONTAINER.
