Claims

1. A JACKETED PIPING SYSTEM COMRISING IN COMBINATION A CASING LINE AND A MATTER TRANSPORTING PIPE LINE SUPPORTED WITHIN THE CASING LINE IN SPACED RELATION TO THE WALLS THEREOF FORMING A FLOW WAY BETWEEN THE CASING LINE AND THE MATTER TRANSPORTING PIPE LINE THROUGHOUT THEIR LENGTHS, THE FLOW WAY BEING DIVIDED INTO SEPARATE COMPARTMENTS THROUGHOUT ITS LENGTH:

(A) A VACUUM PIPE LINE WITHIN AND DISPOSED LONGITUDINALLY OF THE CASING LINE;

(B) BRANCH PIPES EXTENDED FROM THE VACUUM PIPE LINE AT INTERVALS THRORUGHOUT ITS LENGTH CONNECTED TO AND SELECTIVELY COMMUNICABLE WITH ADJACENT COMPARTMENTS OF SAID FLOW WAY;

(C) VACUUM CREATING MEANS CONNECTED TO THE CASTING LINE COMMUNICATING WITH SAID FLOW WAY;

AND (D) MEANS POSITIONED BETWEEN THE VACUUM CREATING MEANS AND THE VACUUM PIPE LINE COMMUNICATING THEREWITH AND OPERABLE TO MAINTAIN A VACUUM OF PREDETERMINED DEGREE IN AND THROUGHOUT THE VACUUM PIPE LINE.
