Abstract

Abstract System for reducing hazards in storing and transporting hazardous material. Container for material includes a chamber containing a phlegmatizer for the material. Chamber has a seal melting, rupturing or releasing at a temperature substantially below the self-accelerating decomposition temperature of the hazardous material, to release the phlegmatizer into the material.

Claims Analysis

Total Claims: 21
Claim 1
Independent Claim 106 words
System for reducing hazards in storing and transporting a hazardous material contained in a container, comprising: a chamber having therein a phlegmatizer for said hazardous material and having discharge means in communication with said hazardous material and said phlegmatizer, separating said hazardous material and said phlegmatizer, and adapted to discharge said phlegmatizer into said hazardous material in said container, said discharge means including a metallic seal in thermal communication with at least said hazardous material and which seal melts, ruptures or releases at a temperature substantially below the self-accelerating decomposition temperature of said hazardous material, whereby said phlegmatizer is released from said chamber into the container.
Claim 2
Dependent Claim 106 words
System for reducing hazards in storing and transporting a hazardous material contained in a container, comprising: a chamber having therein a phlegmatizer for said hazardous material and having discharge means in communication with said hazardous material and said phlegmatizer, separating said hazardous material and said phlegmatizer, and adapted to discharge said phlegmatizer into said hazardous material in said container, said discharge means including a metallic seal in thermal communication with at least said hazardous material and which seal melts, ruptures or releases at a temperature substantially below the self-accelerating decomposition temperature of said hazardous material, whereby said phlegmatizer is released from said chamber into the container.
Claim 3
Dependent Claim 122 words
System adapted for storage or transportation of a hazardous material comPrising: a. a container having charging and discharging means, b. a hazardous material contained in said container, c. a chamber having charging and discharging means, the latter discharging means being in communication with said container, separating said hazardous material and a phlegmatizer for said hazardous material, and adapted to discharge contents thereof into said container, and including therein a metallic seal in thermal communication with at least said hazardous material and which seal melts, ruptures or releases at a temperature substantially below the self-accelerating decomposition temperature of said hazardous material, said chamber containing said phlegmatizer which is released from said chamber into said container as said seal is melted, ruptured or released.
Claim 4
Dependent Claim 122 words
System adapted for storage or transportation of a hazardous material comPrising: a. a container having charging and discharging means, b. a hazardous material contained in said container, c. a chamber having charging and discharging means, the latter discharging means being in communication with said container, separating said hazardous material and a phlegmatizer for said hazardous material, and adapted to discharge contents thereof into said container, and including therein a metallic seal in thermal communication with at least said hazardous material and which seal melts, ruptures or releases at a temperature substantially below the self-accelerating decomposition temperature of said hazardous material, said chamber containing said phlegmatizer which is released from said chamber into said container as said seal is melted, ruptured or released.
Claim 5
Dependent Claim 130 words
System adapted for storage or transportation of an aqueous solution of tertiary butyl hydroperoxide (TBHP) comprising: a. a container having charging and discharging means, b. an aqueous solution of TBHP having a concentration of from about 65 to about 70 percent by weight of TBHP, contained in said first container, c. a chamber having charging and discharging means, the latter discharging means being in communication with and adapted to discharge contents thereof into said container and including therein a metallic seal which melts at a temperature substantially below the temperature at which said aqueous solution of TBHP boils, said chamber containing water in an amount sufficient to reduce said concentration of said TBHP substantially when said seal is melted and said water is released from said chamber into said container.
Claim 6
Dependent Claim 130 words
System adapted for storage or transportation of an aqueous solution of tertiary butyl hydroperoxide (TBHP) comprising: a. a container having charging and discharging means, b. an aqueous solution of TBHP having a concentration of from about 65 to about 70 percent by weight of TBHP, contained in said first container, c. a chamber having charging and discharging means, the latter discharging means being in communication with and adapted to discharge contents thereof into said container and including therein a metallic seal which melts at a temperature substantially below the temperature at which said aqueous solution of TBHP boils, said chamber containing water in an amount sufficient to reduce said concentration of said TBHP substantially when said seal is melted and said water is released from said chamber into said container.
Claim 7
Dependent Claim 45 words
System of claim 3, wherein said aqueous solution of TBHP in (b) has a concentration of about 70 percent by weight, and wherein the amount of water in (c) in said chamber is sufficient to reduce said concentration to 65 percent by weight or less.
Claim 8
Dependent Claim 14 words
System of claim 3, wherein said metallic seal in (c) is an eutectic alloy.
Claim 9
Dependent Claim 26 words
System of claim 3, wherein said metallic seal in (c) is an eutectic alloy melting at about 70*C. and having the following approximate concentration, by weight
Claim 10
Dependent Claim 20 words
System of claim 3, wherein said container of (a) is a steel tank and said chamber is a polyethylene drum.
Claim 11
Dependent Claim 10 words
System of claim 3, including a plurality of said chambers.
Claim 12
Dependent Claim 17 words
System of claim 3, wherein said chamber is immersed in said aqueous solution of TBHP in (b).
Claim 13
Dependent Claim 12 words
System of claim 3, wherein said chamber is affixed to said container.
Claim 14
Dependent Claim 14 words
System of claim 3, wherein said chamber is a partitioned section of said container.
Claim 15
Dependent Claim 12 words
System of claim 11, wherein said discharge means is in the partition.
Claim 16
Dependent Claim 10 words
System of claim 3, wherein said chamber surrounds said container.
Claim 17
Dependent Claim 18 words
System of claim 13, wherein said discharge means is in a wall between said chamber and said container.
Claim 18
Dependent Claim 15 words
System of claim 1, wherein said seal is also in thermal communication with said phlegmatizer.
Claim 19
Dependent Claim 25 words
System of claim 1, including a wall between said chamber and said container, said discharge means being in said wall between said chamber and container.
Claim 20
Dependent Claim 15 words
System of claim 2, wherein said seal is also in thermal communication with said phlegmatizer.
Claim 21
Dependent Claim 25 words
