Abstract: A shredding rotor rotatably coupled to a support frame is configured to remove plant leaves from plant stems fed into an aperture in the support frame. The shredding rotor includes many flexible shredding strands attached to a rotor axle. The shredding strands are sufficiently flexible to strip leaves from all sides of the stems without breaking the stems into pieces. Shredding strands are spaced far enough apart from one another to prevent plant material from becoming lodged between the strands. A destemming and shredding apparatus including two shredding rotors separates an incoming stream of plant materials into an output stream of shredded leaves and another output stream of essentially intact stems. A shredding apparatus having no more than one shredding rotor receives destemmed leaves at an inlet aperture and outputs shredded leaf fragments.

Abstract: An auto-loading firearm having a system for switching between live fire and training modes via a selector switch mounted either on the firearm or on a specially designed training attachment. An action arm is selectively movable in response to movement of the selector switch between a live fire position, in which the firearm is free to operate as normal, and a training mode position where the action arm interrupts operation of the hammer and prevents the firearm from discharging while allowing the trigger and, if present, trigger spring to continue operating.

Abstract: The present invention relates to syringe loading shields for use with syringes during the drawing, calibration and injection of aliquots of radioactive materials. Each syringe loading shield is provided with means for shielding radiation emanating from the mouth of the vial during the material-withdrawal, syringe loading process. In a preferred embodiment, the syringe loading shield comprises a radiation detector for detecting and calibrating the radioactive dosage of the material which is drawn into the syringe barrel. In the preferred embodiment, a substantially tubular syringe shield coupleable to a mouth shield-detector assembly is disclosed which facilitates the drawing, calibration and injection of radioactive materials without exposing the radio-pharmacists to unshielded materials.

In a preferred embodiment, the syringe loading shield comprises a radiation detector for detecting and calibrating the radioactive dosage of the material which is drawn into the syringe barrel. In the preferred embodiment, a substantially tubular shield having a high density viewing window recessed therein is disclosed which is comprised of a plurality of sheaths. A novel hand shield and syringe for use with radioactive materials are also disclosed. spThis is a continuation of application Ser. No. 121,211, filed Feb. 13, 1980 now U.S. Pat. No. 4,307,713.
