Abstract: ABSTRACT OF THE DISCLOSURE An improved biopsy apparatus is disclosed.  The apparatus comprises a hollow outer cannula within which is initially disposed a solid inner puncture trocar.  In use, a biopsy sample is obtained from a patient by first inserting the outer cannula - trocar apparatus into the patient at a desired location.  Thereafter, the solid inner initial puncture trocar is withdrawn from the outer cannula, while the outer cannula remains in place at the desired specimen location.  A hollow inner cannula is then inserted into the outer cannula, and upon withdrawal of the inner cannula from the outer cannula the desired specimen is obtained within the hollow interior of the inner cannula.  In accordance with a second embodiment there is provided an improved rotary biopsy device which includes an elongated inner needle member used for initial penetration of the body tissue, with an outer hollow cylindrical cutting tube thereafter being slidably received over the needle member.  In use, the needle member is first penetrated, by rotating same, into the desired specimen extracting location.  The outer tube is then slidably disposed thereover and pushed downwardly until it also penetrates the body tissue, and both the tube and needle are simultaneously withdrawn with the sample collected interiorly of the tube.

Abstract: ABSTRACT OF THE DISCLOSURE      A crop baling machine of the kind for producing wound bales has a  hollow cylindrical winding compartment having a bottom gap in the compartment cylindrical wall through which the crop is fed by a pick-up device. Conveying rollers then convey the crop to an endless slat conveyor a radially inner run of which is guided at its side edges to sweep round the inner, part cylindrical wall of the compartment.  me outer run of the conveyor is guided round the outside of this wall.  A rear compartment portion is hinged to open upwardly to release the bale. The construction is relatively simple and robust and requires less power than conventional machines because uniform radial compression of the bale is achieved.  Also, dust and particles of crop cannot easily escape from the baling compartment.
