  • Patent number: 4635862
    Abstract: A rotary granulator having a rotor positioned coaxially within a cutting chamber defined by a multi-perforate cylindrical screen mounted on an end plate with a fixed bed knife projecting into the cutting chamber in position to cooperate with a rotor knife in cutting up stock introduced axially into the cutting chamber through the end of the chamber opposite the end plate. The rotor includes a hub adjacent the end plate and at least two spaced rotor arms projecting from the hub parallel to the cutting chamber axis with the rotor knife mounted on a rotor arm. An annular rotor bearing member is mounted on the ends of the rotor arms opposite the hub within a fixed bearing member; the two bearing members comprise an outboard guide/support bearing for the rotor, affording support for the rotor but allowing unimpeded axial feed into the cutting chamber.

  • Patent number: 4158539
    Abstract: A thermoforming machine having opposed mold platens includes a linkage system driven in cyclic movement by a single rotary cam to cyclically shift the platens between their open and closed position. The cam is driven by a variable speed motor which is controlled in a manner such that the rotary speed of the cam during different portions of a cam revolution may be set to a speed which is different than the rotary speed of the cam during other portions of each revolution. By adjusting the speed differential or by adjusting the angular extent of that portion of a revolution of the cam over which the different speed is maintained the time duration of any chosen portion of the cycle may be adjusted independently of the time duration of other portions of the cycle. The platens are mounted for reciprocatory movement upon a three-post frame.
