Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
116 words
A sterilizing apparatus comprising: an ozone generator capable of operating at pressures from about 500 pounds per square inch to about 5000 pounds per square inch; said ozone generator connected to a holding tank for receiving ozone under pressure wherein said ozone is mixed with water; said holding tank connected to a sterilizing chamber which includes a means for receiving the water and ozone mixture and a means for releasing the said mixture received from said holding tank as a humid gas mixture into the said sterilizing chamber; said sterilizing chamber connected to a means for evacuating said sterilizing chamber prior to release of said mixture, and a means for withdrawing the mixture from said chamber.
Claim 2
Dependent Claim
116 words
A sterilizing apparatus comprising: an ozone generator capable of operating at pressures from about 500 pounds per square inch to about 5000 pounds per square inch; said ozone generator connected to a holding tank for receiving ozone under pressure wherein said ozone is mixed with water; said holding tank connected to a sterilizing chamber which includes a means for receiving the water and ozone mixture and a means for releasing the said mixture received from said holding tank as a humid gas mixture into the said sterilizing chamber; said sterilizing chamber connected to a means for evacuating said sterilizing chamber prior to release of said mixture, and a means for withdrawing the mixture from said chamber.
Claim 3
Dependent Claim
73 words
The apparatus of claim 1, further comprising: a means for bleeding ozone from said sterilizing chamber and passing said ozone over a catalyst for converting said ozone into oxygen; a means for switching the ozone generator on when the ozone in the holding tank is less than 6 percent by weight; a means for switching the ozone generator off when the ozone in the holding tank is greater than 10 percent by weight.
Claim 4
Dependent Claim
25 words
The apparatus of claim 1, further comprising: a means of measuring the concentration of said ozone in said catalyst by the temperature of said catalyst.
Claim 5
Dependent Claim
27 words
The apparatus of claim 1, further comprising: a means for extracting oxygen up to 85 percent by weight from air; said means connected to the ozone generator.
Claim 6
Dependent Claim
31 words
The apparatus of claim 1, further comprising: a means of having said ozone bypass said sterilizing chamber connected to said catalyst during the time when said sterilizing chamber is being evacuated.
Claim 7
Dependent Claim
22 words
The apparatus of claim 1, further comprising: a means of having multiple cycles of the operations described in claims 1 through 5.
