Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
110 words
IN A PROCESS FOR THE COLD DEFORMATION OF ALUMINUM, THE STEP OF LUBRICATING THE SURFACE OF THE ALUMINUM WITH A COMPOSITION CONSISTING ESSENTIALLY OF: (A) A HYDROCARBON OIL HAVING NOT MORE THAN A SLIGHT TENDENCY TO PRODUCE STAINS ON ALUMINUM WHEN WHEN HEATED IN CONTACT THEREWITH, (B) AN AMOUNT SUFFICIENT TO IMPROVE THE LOAD-BEARING CAPACITY OF SAID HYDROCARBON OIL OF AT LEAST ONE SATURATED ALIPHATIC ALCOHOL HAVING AT LEAST 7 CARBON ATOMS, (C) FROM ZERO TO AN AOMOUNT AT LEAST SUFFICIENT TO ENSURE THE SPREAD OF THE LUBRICANT OVER THE ENTIRE SURFACE OF THE METAL TO BE DEFORMED OF A SURFACE-WETTING AGENT, AND FROM ZERO TO ABOUT 2% PALM OIL.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
123 words
A PROCESS FOR THE PRODUCTION OF PART-HARD ALUMINUM SHEET MATERIAL, COMPRISING COLD ROLLING ALUMINUM, WHILST LUBRICATING IT WITH A COMPOSITION CONSISTING ESSENTIALLY OF (A) A CLOSE-CUT HYDROCARBON OIL HAVING SUBSTANTIAL FREEDOM FROM FORMATION OF BROWN STAINS WHEN HEATED IN CONTACT WITH ALUMINUM, (B) AN AMOUNT SUFFICIENT TO IMPROVE THE LOAD-BEARING CAPACITY OF SAID HYDROCARBON OIL OF A STRAIGHT CHAIN ALIPHATIC ALCOHOL CONTAINING 9 TO 12 CARBON ATOMS AS A LOAD-BEARING ADDITIVE, AND (C) FRO ZERO TO AN AMOUNT SUFFICIENT TO ENSURE THE SPREAD OF THE LUBRICANT OVER THE ENTIRE SURFACE OF THE METAL TO BE DEFORMED OF A SURFACE-WETTING AGENT, AND SUBSEQUENTLY ANNEALING THE ROLLED ALUMINUM AT A TEMPERATUER IN THE RANGE OF ABOUT 180* TO 260*C. TO DRAW IT BACK TO PART-HARDNESS.
