Abstract: Two cooperating rotors are mounted for counter rotation about parallel axes for passage of crop between the rotors. At least one rotor has stiff, resilient, outwardly directed crop engaging elements having sharp tips on the outer ends for treating crop. The rotors rotate with the outer perimeters of the rotors overlapping and with regular inter-meshing of crop engaging elements on one rotor with crop engaging elements on the other rotor. Crop engaging elements of one rotor press crop into gaps between crop engaging elements on the other rotor so that the crop is laid across the sharp tips of the elements to treat the crop by a spiking action. The crop engaging elements may be outwardly extending fins, or transversely extending ribs of discs perpendicular to the axis of rotation. The crop engaging elements may have specified yielding characteristics, being yieldable in a preferred direction and being yieldable predominantly at a region spaced from the outer tip.

Abstract: Nuts on the ground are propelled by an air jet issuing from one tubular branch of a hand-held nut harvester into an opposing conveyor branch where the nuts are lifted until they strike a deflector in a separator chamber. Deflected nuts descend from the separator chamber to an attached collection receptacle. Debris entrained with nuts in the conveyor branch of the harvester is subjected to a venturi action produced by convex and concave spoon-like elements in the throat of the separator chamber immediately beyond the nut deflector and is swept through a rear downturned debris conduit or horn. The harvester can clear itself of debris through operation of an air stream diverter valve which diverts most of the harvesting air stream produced by a back-pack blower on a reverse path through the conveyor branch of the harvester.

Abstract: Method of and apparatus for producing twistless yarns from glued together separate fibers. Tape from interrupted or continuous fibers is fed by a pair of rollers, and moving in a straight line, is turned circularly or gyrated by a whirling air flux and as a result is false twisted. The false twisted tape, rotating circularly, passes through a recirculating glue solution by entering the top surface of a pool thereof. Passing through the glue solution, the tape is covered with glue, and carries away part of the glue solution toward a calender pair of rollers, which are thus kept always in a constant wet condition. Glue solution running out from the calender pair of rollers deviates from the trajectory of the moving tape, and glides along the working surface of the lower calender roller. The quantity of the glue thus taken away form the fibrous tape can be controlled and regulated.

Exhaust gas from the volute impinges on the turbine wheel after passing between stationary vanes 60 in an annular inlet passage between thin wall 52 and wall 46 of turbine housing 40.

Abstract: The invention is a novel rotational viscometer which is well adapted for use with fluids at high temperatures and/or pressures. In one embodiment, the viscometer includes a substantially non-magnetic tube having a closed end and having an open end in communication with a fluid whose viscosity is to be determined. An annular drive magnet is mounted for rotation about the tube. The tube encompasses and supports a rotatable shaft assembly which carries a rotor, or bob, for insertion in the fluid. Affixed to the shaft are (a) a second magnet which is magnetically coupled to the drive magnet and (b) a third magnet. In a typical operation, the drive magnet is rotated to turn the shaft assembly while the shaft rotor is immersed in the fluid. The viscous drag on the rotor causes the shaft assembly to lag the rotation of the drive magnet by an amount which is a function of the amount of viscous drag. A first magnetic pickup generates a waveform whose phase is a function of the angular position of the drive magnet.

Abstract: A test apparatus and method tests for closure of ganged, cam operated main control valves in a steam turbine. Cam actuation of a set of upper main control valves is separated from cam actuation of a lower set of main control valves. A test controller actuates one of the sets of main control valves in the opening or closing direction and holds the other set stationary while monitoring turbine power output. When the power output has changed by a predetermined amount, the test controller halts actuation of the first-actuated set of main control valves and begins actuating the other set of main control valves in the opposite direction until the turbine power output has changed a predetermined amount in the opposite direction. The process of incrementally closing one set while incrementally opening the other set of main control valves is continued until the set of main control valves being moved in the closing direction should be fully closed.
