US Patent 4,194,540 (granted March 25, 1980) to James R. Reynolds, assigned to Milliken Research Corporation, describes a water jet loom that recycles heat from the weft-suction vacuum blower to the fabric dryer. This reduces the electrical heat needed to dry the fabric before take-up. The document includes the abstract, ten claims, a description of the loom (weft insertion, reed, leno selvedges, heater), and three sheets of drawings. It exists in two forms: a USPTO web database printout and the patent's printed pages.
