A mill roll for a juice extracting system having a plurality of circumferential grooves and a plurality of spiral flow passages extending from end to end below the surface of the roll. A plurality of holes around each circumferential groove open into the flow passages so that juice squeezed between the rolls flows through the holes and out the spiral passages. With the passages disposed spirally, the rolls may be used as the bottom roll in a three roll mill because juice squeezed between the top roll and a bottom roll and flowing into a channel will exit below the restraining flange normally provided on the top roll.
Disclosed is a maceration system of the type generally used in the grinding and juice extraction of sugar cane. The last mill has a roll and feed and discharge bottom rolls with elongated trash plate spanning the space between the bottom rolls. Separate troughs extend below each of the bottom rolls to catch and separate juice therefrom. The top roll has longitudinal flow passageways around it opening into ports in the roll surface and water is introduced through these passgeways to flow into the pulp moving over the trashplate to the discharge roll, and the juice from below the discharge roll is directed to the pulp moving to the feed roll. In the case of multiple mills in tandem, the juice recovered from the feed roll is directed to the top roll passageways of the previous mill and the juice from the discharge roll of that mill is directed to the feed roll thereof.

Abstract:
A cylindrical shell has a conical bottom with a central outlet therein. A hollow central shaft is rotatably and vertically supported within the center of the shell and has attached thereto at least one heat exchange element including lower and upper radial tubes. Hollow rectangular ducts extend vertically between the upper and lower radial tubes. Heat exchange fluid flows from the upper end of the shaft, radially outwardly through the lower radial tubes, upwardly through the rectangular ducts, radially inwardly through the upper radial tubes, and to the upper end of the shaft.

Abstract:
Apparatus for treating human joints wherein a machine reciprocates to flex the joint while an electrical stimulator causes contraction of muscles affected by the flexing. Switches disposed along the path of machine movement are tripped to energize the stimulator current during selected stages of the machine movement, and in either or both directions.
