Patent CA-2104758-A1 (CA)
Inventor: UEYAMA UKIO
IPC: A61M5/32
Filed: 1993-08-24
Abstract: ABSTRACT OF THE DISCLOSURE    A syringe comprises, besides a barrel, a plunger and a needle 3, a needle holding stopper, a needle hole stopper, a spring connecting the needle holding stopper and needle hole stopper and a lock mechanism provided between the barrel and the needle holding stopper. The lock mechanism functions such  that  it  fixes  the  needle  holding  stopper  until completion of injection so that the needle is not pushed up into the hinder part of the barrel, and that it is released when the plunger is further pressed, i.e. by a single finger motion,  after  completion  of  the  injection,  so  that  the needle holding stopper is pushed up by force of the spring, thereby hangaring the needle in the barrel and, at the same time, the needle hole stopper is moved to close the needle hold  on  the  end  of  the barrel.   The  syringe  causes  no accident of pricking finger with the needle after injection operation or oozing out of the blood or the like of the patient adhered on the needle tip.

Title: Jam-Free Bulk Loader for a Paintball Gun
Inventor: BELL RODERICK L
IPC: F41B11/02
Filed: 1993-09-01
Abstract: An essentially jam-free bulk loader for a semi-automatic paintball gun includes a storage housing positionable above the gun infeed opening and adapted to hold a quantity of paintballs to be gravity fed to and fired by the gun.  Extending downwardly from a bottom outlet opening in the housing is a feed tube having a bottom end portion connectable to outer end of the gun infeed elbow.          During normal operation of the loader, a series of paintballs fall into the tube and infeed elbow and are vertically stacked therein for sequential downward delivery to the gun through the inner end of the infeed elbow.  If a paintball jam occurs within the storage housing above its outlet opening during firing of the gun, a void is created in a top end portion of the feed tube above the downwardly moving paintball stack.  An optical sensor detects the void and responsively actuates a motor driven agitator member within the storage housing adjacent its bottom outlet opening.  The driven agitator member forcibly engages and shifts the jamming paintballs to permit additional paintballs to fall through the housing outlet opening into the feed tube and return the paintball delivery stack to its full operating height within the tube and infeed elbow.  When this occurs, the sensor detects the filling of the tube void and responsively terminates the operation of the agitator member until it is needed again.

Title: Grading and evaluation of poultry with ultrasound
Inventor: STOUFFER JAMES R
IPC: A22B5/00
Filed: 1992-08-24
Abstract: Method and apparatus for grading poultry and determining a condemnation in an animal or carcass intended for human consumption is taught hereinabove. The apparatus includes an ultrasound machine, including  a probe, wherein the probe is positioned on the animal such that an image of the portion of the animal to be examined is shown. An image analyzer determines and identifies a pattern of anatomically distinct tissue and bone outline of the animal shown on the image. Pattern re-cognition equipment compares the pattern of tissue and bone outline with a norm reference for a healthy animal and at least one known deformation pattern for tissue of animals requiring condemnation. If a greater correlation with one of the known deformation patterns than with the norm reference pattern is shown then, means for indicating a condemnation condition  for the animal are activated. The probe is positioned on the carcass parallel to the keel such that the image of the breast muscle of the carcass is detected by the ultrasound machine. A breast muscle size indicator of the breast muscle is determined from the detected image. The calculation of a grade for the carcass is based upon the ratio of the indicator to the weight of the carcass.
