Abstract
Abstract A reserve cell designed to be activated by a push-pin, and provided with a sealed enclosure having a guide hole of small dimension to prevent temptation of tampering and activation when openly exposed, and a protective housing for the cell embodying a push-pin element to serve as a tool to activate the cell when deisred, with means serving as a detent to prevent undesired activation by said housing.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
259 words
A combination reserve cell and housing for protectively storing and covering the cell while awaiting activation, and the housing serving to activate the cell, when desired, said combination comprising: a reserve cell having a container enclosing a cathode, an anode, a separator in the space therebetween, and a sealed vessel of electrolyte, all within said container; an axially movable sealing element embodied by said reserve cell, constituting means designed to be operable by an external actuating element for opening said sealed vessel to release said electrolyte, to permit and enable said electrolyte to enter the effective, operating space occupied by the separator between said anode and cathode; a guide means disposed in line with a selected region of said sealing element that is to be moved by said external actuating element; means normally serving as a protective and enclosing housing for said reserve cell to hold the cell unactivated and to prevent casual undesired activation of said cell, wherein said housing embodies an element to serve as said external actuating element to move the sealing element to open said sealed vessel, said housing consisting of a deep upper hollow cylindrical cup and a shallow lower hollow cylindrical cup to serve as a closure cap for said upper cup, said upper housing cup carrying the actuating element that moves said sealing element; and a removable disposable spacer disposed in said upper housing cup, between the cup and the top of said cell, to prevent casual undesired actuation by said actuating element until such actuation is desired and the spacer removed.
Claim 2
Dependent Claim
259 words
A combination reserve cell and housing for protectively storing and covering the cell while awaiting activation, and the housing serving to activate the cell, when desired, said combination comprising: a reserve cell having a container enclosing a cathode, an anode, a separator in the space therebetween, and a sealed vessel of electrolyte, all within said container; an axially movable sealing element embodied by said reserve cell, constituting means designed to be operable by an external actuating element for opening said sealed vessel to release said electrolyte, to permit and enable said electrolyte to enter the effective, operating space occupied by the separator between said anode and cathode; a guide means disposed in line with a selected region of said sealing element that is to be moved by said external actuating element; means normally serving as a protective and enclosing housing for said reserve cell to hold the cell unactivated and to prevent casual undesired activation of said cell, wherein said housing embodies an element to serve as said external actuating element to move the sealing element to open said sealed vessel, said housing consisting of a deep upper hollow cylindrical cup and a shallow lower hollow cylindrical cup to serve as a closure cap for said upper cup, said upper housing cup carrying the actuating element that moves said sealing element; and a removable disposable spacer disposed in said upper housing cup, between the cup and the top of said cell, to prevent casual undesired actuation by said actuating element until such actuation is desired and the spacer removed.
Claim 3
Dependent Claim
34 words
A combination reserve electric cell, with a housing for protectively storing the cell and for activating the cell, when desired, as in claim 1, said cell and housing comprising a. a cell structure including

3 words
a concentric anode,
Claim 6
Dependent Claim
2 words
a cathode,
Claim 7
Dependent Claim
2 words
a cathode,
Claim 8
Dependent Claim
71 words
A combination cell and housing, as in claim 1, in which the length of the upper housing cup and the effective operating length of the actuating element are such that when the bottom cup and the removable spacer are removed and the cell rested on a supporting base, the upper housing cup may be pressed downwardly to cause the actuating element on the upper housing cup to move the sealing element.
Claim 9
Dependent Claim
183 words
A reserve cell and housing combination, as in claim 1, comprising a reserve cell having axially extending polar electrodes separated by a radial space, and a vial containing an isolated and confined electrolyte therein for ultimate operative disposition in said space between said electrodes, and an enclosure for said cell components with an element of said enclosure constituting a top diaphragm having a predeteremined limited path of axial movement, and fracturable means within said container and subject to fracture by said diaphragm within its path of movement when said diaphragm is impelled by an external force; and a housing for said cell, said housing consisting of an elongated inverted hollow top cup slidably fitting over the top of said cell, and of a shallow hollow bottom cup slidably fitting over the bottom of said cell, with a binding strip encircling the housing and holding both top cup and bottom cup together, with spacer means for fixedly positioning said cell within said housing against casual relative shifting, so long as said binding strip is in place and activation of said cell is not desired.
Claim 10
Dependent Claim

an absorbent separator in a space between said anode and said cathode,
Claim 11
Dependent Claim
12 words
an absorbent separator in a space between said anode and said cathode,
Claim 12
Dependent Claim

Claim 13
Dependent Claim
17 words
a vial co-axially disposed and having top and bottom frangible end walls, and containing a liquid electrolyte.
Claim 14
Dependent Claim
112 words
A combination reserve cell and housing, as in claim 1, comprising said reserve cell as a self-complete unit and embodying a movable element for activating said cell, and a guide means for directing an external force onto said movable element; a housing enclosing said cell and preventing casual actuation of said movable element, said housing including an actuating element aligned to enter said guide means to impress a force on said movable element; spacing means for holding said actuating element from said movable element; and said housing being movable, upon removal of said spacing means, to move said actuating element to impress a force on said movable element to activate said cell.
Claim 15
Dependent Claim
160 words
an upper end closure for said container consisting of a transverse circular diaphragm having a co-axial central element re-entrantly shaped having axial freedom and axially movable by an applied external force, with said element able to cause fracture of said top and bottom frangible end walls of said vial to release the electrolyte from said vial to fill the space containing said absorbent separator between anode and cathode, and to render the cell active; b. an outer shell substantially surrounding said sealed inner container, and including guide means for guiding an intended external force element to act against said central re-entrant movable element of said diaphragm to cause said axially movable element of said diaphragm to achieve said fracturing action; c. and means normally serving as part of an external protective housing for said cell, and embodying a force element for rendering said reserve cell active by operation of said housing acting against said axially movable element of said diaphragm.
Claim 16
Dependent Claim
