Abstract: The biopsy needle device has an axially elongated stylet and a cannula coaxially disposed thereabout, the stylet and cannula being mounted on stylet and cannula bases that are slidably mounted within a cavity of an elongate housing. The cavity also contains a spring-loaded firing mechanism for firing the stylet and cannula for taking a tissue sample from a patient. The stylet base contains a safety stylet latch lever and a firing stylet latch lever for retaining the stylet in the first, retracted position until released. The cannula base includes a safety cannula latch lever and a locking cylinder for retaining the cannula base in the first retracted position until released. Once the safety and firing stylet latch levers have been released, the stylet base advances to contact a finger of the stop pad, thereby releasing the safety cannula latch lever. The tissue of the patient prolapses into a side-facing notch of the advancing stylet.

Abstract: Soft tissue biopsy apparatus (10) for obtaining a tissue specimen. An elongate housing (12) has an opening (20) at one end (14). A hollow cannula (26) is positioned within the housing, is reciprocally movable therewithin, and one end (28) of the needle extends through the opening for insertion into tissue (T) from which a specimen is to be taken. A needle (44) is positioned within the cannula, is reciprocally movable therewithin, and also has an end (46) extending through the opening for insertion into the tissue. This needle has a recess (50) adjacent its outer end in which a tissue specimen is captured. The needle is connected to a slide (68) by which the needle is moved independently of the cannula. A sleeve (110) installed over the housing is manually operable to move the slide to a selected and cocked position prior to insertion of the cannula/needle into the tissue. Movement of the slide moves the second needle from a first position to a second position while the cannula remains stationary.

Abstract: A continuously operating bead filler assembly system for forming filler material on top of a tire bead includes a multiple station assembly machine having at least one station for placing the bead and positioning the filler material in cylindrical form adjacent the bead and at least one station for forming and rotating the filler material on top of the bead. The multiple station assembly machine is used in conjunction with a rubber extruder, which continuously extrudes the filler material onto an accumulator, which delivers the filler material to a cutting and measuring device which cuts the filler material in predetermined lengths for deposit of the filler material in cylindrical form onto accumulator station.

Abstract: A retractable bead setter assembly of the present invention for use with a tire building machine is comprised of a tire bead placing and end ply turn-up bag pusher means having a plurality of first segment elements movable radially therein and a plurality of alternately spaced second segment elements movable both radially and axially. The bead portion of the bead and filler material is positioned adjacent to the first segment elements and firmly gripped between the first and second segment element. The tire bead placing and end ply turn-up bag pusher means is axially moved inwardly to an inward bead set position perpendicular to the axis of rotation of the tire building machine and the clamp lock means is expanded radially to lock the tire carcass material to the bead.
