Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
70 words
A CORROSION-INHIBITING COMPOSITION WHICH COMPRISES A LIQUID VEHICLE WHICH TENDS TO PERMIT THE CORROSION OF METAL IN THE SERVICE TO WHICH SAID VEHICLE IS PUT, CONTAINING A MEMBER SELECTED FROM THE GROUP CONSISTING OF N-(N-DODECYLBENZENESULFONYL) SARCOSINE AND N-(N-DODECYLBENZENESULFONYL) IMINOACETIC ACID, SAID MEMBER BEING PRESENT IN SAID LIQUID VEHICLE IN AMOUNT OF AS LITTLE AS A FRACTION OF 1% BY WEIGHT BUT IN ASUFFICIENT QUANTITY TO INHIBIT CORROSION OF SAID VEHICLE.
Claim 2
Dependent Claim
70 words
A CORROSION-INHIBITING COMPOSITION WHICH COMPRISES A LIQUID VEHICLE WHICH TENDS TO PERMIT THE CORROSION OF METAL IN THE SERVICE TO WHICH SAID VEHICLE IS PUT, CONTAINING A MEMBER SELECTED FROM THE GROUP CONSISTING OF N-(N-DODECYLBENZENESULFONYL) SARCOSINE AND N-(N-DODECYLBENZENESULFONYL) IMINOACETIC ACID, SAID MEMBER BEING PRESENT IN SAID LIQUID VEHICLE IN AMOUNT OF AS LITTLE AS A FRACTION OF 1% BY WEIGHT BUT IN ASUFFICIENT QUANTITY TO INHIBIT CORROSION OF SAID VEHICLE.
Claim 3
Dependent Claim
80 words
A RUST-INHIBITED OLEAGINOUS COMPOSITION ADAPTED FOR USE IN THE PRESENCE OF WATER IN SYSTEMS CONTAINING METAL SUSCEPTIBLE TO CORROSION BY SAID WATER, COMPRISING AN OLEAGINOUS VEHICLE, A MEMBER SELECTED FROM THE GROUP CONSISTING OF N-(N-DODECYLBENZENESULFONYL) SARCOSINE AND N-(N-DODECYLBENZENESULFONYL) IMINOACETIC ACID IN AMOUNTS OF AS LITTLE AS A FRACTION OF 1% BUT IN SUFFICIENT QUANTITY TO INHIBIT CORROSION OF SAID METAL, AND AN ALKYL PRIMARY AMINE HAVING 18-24 CARBON ATOMS IN SUFFICIENT AMOUNT TO SOLUBILIZE SAID MEMBER IN THE OLEAGINOUS VEHICLE.
Claim 4
Dependent Claim
80 words
A RUST-INHIBITED OLEAGINOUS COMPOSITION ADAPTED FOR USE IN THE PRESENCE OF WATER IN SYSTEMS CONTAINING METAL SUSCEPTIBLE TO CORROSION BY SAID WATER, COMPRISING AN OLEAGINOUS VEHICLE, A MEMBER SELECTED FROM THE GROUP CONSISTING OF N-(N-DODECYLBENZENESULFONYL) SARCOSINE AND N-(N-DODECYLBENZENESULFONYL) IMINOACETIC ACID IN AMOUNTS OF AS LITTLE AS A FRACTION OF 1% BUT IN SUFFICIENT QUANTITY TO INHIBIT CORROSION OF SAID METAL, AND AN ALKYL PRIMARY AMINE HAVING 18-24 CARBON ATOMS IN SUFFICIENT AMOUNT TO SOLUBILIZE SAID MEMBER IN THE OLEAGINOUS VEHICLE.
