Patent number: 3955579Abstract: A vacuum curet of novel design having a central portion which is tapered and an internal lumen which is preferably also tapered. This provides a curet which is rigid over its central and proximal end (i.e. the end that fits into a vacuum source) and maximal flexibility and small external diameter at its distal end portion. Further advantages of this arrangement are reducing the possibility of perforation (due to the flexibility of the distal end portion), better "feel" (due to the rigidity of the central and proximal end portion), and decreased trauma due to the thin wall thickness of the proximal end portion and a corresponding reduction in outside diameter for a given or required lumen diameter. The lumen of this design may also be mass produced. In an additional embodiment, there is a novel design on the tip openings at the distal end, which further minimizes the possibility of perforation.Type: GrantFiled: July 23, 1973Date of Patent: May 11, 1976Inventor: Henry Bridgman

Patent number: 3955580Abstract: The identification tag is in the form of a flexible plastic disc having a fastening portion in the shape of an inverted T, the stem of the T extending from a peripheral portion of the disc. A U-shaped strip of metal serves as an inserting tool and is arranged to straddle the disc, a first arm terminating in a square end and the second arm being longer than the first arm and terminating in a point. The arrangement is such that the inverted T-shape can be flexed towards an upright position so that the square end of the first arm can be received between the stem and cross portion of the T with the second arm holding the underside of the second cross portion of the T and stem in their flexed positions. A cow's ear is then pierced by the point on the second arm, the first arm urging the T-shape through the cut opening. Withdrawal of the U-shaped arms then permits the T-shape to flex back to its normal position to secure the tag to the cow's ear.Type: GrantFiled: March 20, 1975Date of Patent: May 11, 1976Inventor: Roy Dale Thompson
