Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
112 words
THE METHOD OF MAKING GREASE WHICH COMPRISES: CONSTITUTING A MIXTURE COMPRISING AN OLEGINOUS VEHICLE, A SAPONIFYING AGENT AND FATTY MATERIAL SELECTED FROM THE GROUP CONSISTING OF A FATTY ACID AND A GLYCERIDE, FORMING A SOAP THICKENING AGENT IN SITU IN THE VEHICLE, AND COOLING THE RESULTANT MIXTURE TO A TEMPERATURE BELOW ITS SOLUTION TEMPERATURE WHEN THE SOAP THICKENING AGENT IS FORMED AT A TEMPERATURE ABOVE THE SOLUTION TEMPERATURE, SUBJECTING THE RESULTING VEHICLE-SOAP MIXTURE, AT A TEMPERATURE ABOVE ABOUT 212*F. AND BELOW ITS SOLUTION TEMPERATURE, TO MECHANICAL ATOMIZATION INTO DISPERSED DROPLETS AND INSTANTANEOUSLY CONTACTING THE SAID DROPLETS DIRECTLY WITH A SUBSTANTIALLY COOLER SURROUNDING ATMOSPHERE TO EFFECT HEAT EXCHANGE THEREOF, THEREBY FORMING A GREASE.
