Abstract
Abstract 1. An electro-chemical interval timing device comprising a casing, an eleolyte within said casing, a cap sealing said casing, a lead cathode carried by said cap and extending into said casing contained electrolyte at one end and extending beyond said cap outwardly of said casing at the other end, a plurality of silver anodes, means for mounting said anodes in said cap to provide outside connection posts for one end of each of said anodes, the other end of each anode being formed with a rounded head of exact predetermined size and shape, said head extending into said electrolyte, a plurality of cups carried by said caps respectively, each cup partially housing one of said anodes, a plurality of spring biased plugs, each of said plugs being partially housed by one of said cups and connected to one of said anodes, means retaining each of said anodes to their attached plug, a plurality of battery energized circuits each connected to said cathode and to one of said anodes, a variable resistance in each of said circuits, means initiating said battery energized circuits, a second plurality of circuits, each of said second circuits including an open switch positioned adjacent one of said spring biased plugs whereby the energization of said battery energized circuits will cause current to pass through the electrolyte and dissolve the heads of said anodes at an equal rate, said plugs and their attached anodes being released by the dissolving of said anode heads in accordance with their different sizes and shapes.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
253 words
An electro-chemical interval timing device comprising a casing, an electrolyte within said casing, a cap sealing said casing, a lead cathode carried by said cap and extending into said casing contained electrolyte at one end and extending beyond said cap outwardly of said casing at the other end, a plurality of silver anodes, means for mounting said anodes in said cap to provide outside connection posts for one end of each of said anodes, the other end of each anode being formed with a rounded head of exact predetermined size and shape, said head extending into said electrolyte, a plurality of cups carried by said caps respectively, each cup partially housing one of said anodes, a plurality of spring biased plugs, each of said plugs being partially housed by one of said cups and connected to one of said anodes, means retaining each of said anodes to their attached plug, a plurality of battery energized circuits each connected to said cathode and to one of said anodes, a variable resistance in each of said circuits, means initiating said battery energized circuits, a second plurality of circuits, each of said second circuits including an open switch positioned adjacent one of said spring biased plugs whereby the energization of said battery energized circuits will cause current to pass through the electrolyte and dissolve the heads of said anodes at an equal rate, said plugs and their attached anodes being released by the dissolving of said anode heads in accordance with their different sizes and shapes.
Claim 2
Dependent Claim
253 words
An electro-chemical interval timing device comprising a casing, an electrolyte within said casing, a cap sealing said casing, a lead cathode carried by said cap and extending into said casing contained electrolyte at one end and extending beyond said cap outwardly of said casing at the other end, a plurality of silver anodes, means for mounting said anodes in said cap to provide outside connection posts for one end of each of said anodes, the other end of each anode being formed with a rounded head of exact predetermined size and shape, said head extending into said electrolyte, a plurality of cups carried by said caps respectively, each cup partially housing one of said anodes, a plurality of spring biased plugs, each of said plugs being partially housed by one of said cups and connected to one of said anodes, means retaining each of said anodes to their attached plug, a plurality of battery energized circuits each connected to said cathode and to one of said anodes, a variable resistance in each of said circuits, means initiating said battery energized circuits, a second plurality of circuits, each of said second circuits including an open switch positioned adjacent one of said spring biased plugs whereby the energization of said battery energized circuits will cause current to pass through the electrolyte and dissolve the heads of said anodes at an equal rate, said plugs and their attached anodes being released by the dissolving of said anode heads in accordance with their different sizes and shapes.
Claim 3
Dependent Claim
134 words
An electro-chemical device comprising; a casing, a cathode carried within said casing and having a connection extending through said casing, an electrolyte within said casing in contact with said cathode, an anode in said casing partially in contact with said electrolyte, resilient means urging said anode in a first direction, said anode having a portion of increased diameter said portion being in contact with said electrolyte, abutment means in abutting contact with said enlarged portion retaining said anode in a first position, a battery energized open circuit connected to said cathode and said anode, means for closing said circuit whereby, when said circuit is closed, said enlarged portion undergoes electro-chemical decomposition whereupon, said anode is releaded from abutting contact with said abutment means and is moved to a second position by said resilient means.
Claim 4
Dependent Claim
134 words
An electro-chemical device comprising; a casing, a cathode carried within said casing and having a connection extending through said casing, an electrolyte within said casing in contact with said cathode, an anode in said casing partially in contact with said electrolyte, resilient means urging said anode in a first direction, said anode having a portion of increased diameter said portion being in contact with said electrolyte, abutment means in abutting contact with said enlarged portion retaining said anode in a first position, a battery energized open circuit connected to said cathode and said anode, means for closing said circuit whereby, when said circuit is closed, said enlarged portion undergoes electro-chemical decomposition whereupon, said anode is releaded from abutting contact with said abutment means and is moved to a second position by said resilient means.
Claim 5
Dependent Claim
46 words
An electro-chemical timing device according to claim 2 wherein said abutment means comprises a partition member having an aperture therein, said anode having a portion of reduced diameter less than the diameter of said aperture and said enlarged portion has a diameter greater than said aperture.
Claim 6
Dependent Claim
142 words
An electro-chemical timing device comprising; a casing, an electrolyte within said casing, a cathode having a first portion thereof in contact with said electrolyte having a second portion extending through said casing, said casing further including a plurality of cup-shaped members extending into said electrolyte, each of said cup-shaped members having an aperture through the bottom portion thereof, each of said cup-shaped members having a spring biased plug therein, each of said plugs having a central bore therethrough, each of said bores having an anode therein, each of said anodes having a portion extending through one of said apertures, each of said anodes having an enlarged portion of a diameter greater than said aperture, whereby, upon electro-chemical decomposition of said enlarged portions of said anodes, said anodes and said containing plugs are moved due to the force exerted by said resilient means.
Claim 7
Dependent Claim
142 words
An electro-chemical timing device comprising; a casing, an electrolyte within said casing, a cathode having a first portion thereof in contact with said electrolyte having a second portion extending through said casing, said casing further including a plurality of cup-shaped members extending into said electrolyte, each of said cup-shaped members having an aperture through the bottom portion thereof, each of said cup-shaped members having a spring biased plug therein, each of said plugs having a central bore therethrough, each of said bores having an anode therein, each of said anodes having a portion extending through one of said apertures, each of said anodes having an enlarged portion of a diameter greater than said aperture, whereby, upon electro-chemical decomposition of said enlarged portions of said anodes, said anodes and said containing plugs are moved due to the force exerted by said resilient means.
