Abstract: A piercing station for piercing sample container caps or thick stoppers. The piercing station has a structural frame with two vertical guide rods. A carriage assembly is slidably mounted on the guide rods and is further driven to move up and down along the guide rods. The carriage assembly carries a blade holder, which in turn holds a piercing blade assembly. The blade assembly includes a center blade and two cross blades interlocked together, such that the blade assembly has a generally modified “H”-shaped cross section for piercing a cap on the sample container. Lubricant left in or on the sample container cap by the piercing station reduces the force required by the sample probe to penetrate thick stoppers for sample aspiration and level sensing. The “H”-shaped cut helps to equalize the pressure in the sample container during sampling, so that clot detection is more effective.

Abstract: A combination food preparation and handling tool comprises a handled main blade body, a turning hook, and a pair of legs protruding from the main blade body. In the preferred embodiment, the turning hook is integrally formed from an extended and pointed tip of the main blade body formed into the desired shape and bent at an angle to the main blade body. One edge of the main blade body is preferably arcuate in shape and sharpened to form a primary cutting edge. The legs can form a bottle de-capper and a secondary cutting edge. The preferred arrangement of the main blade body, the turning hook and the legs forms a likeness of a legged animal, such as an alligator. Further enhancement of the animal appearance may be had through etchings or engravings on the main blade body to represent other features of the animal.

Abstract: A monofilament line for a rotating string trimmer has a main body portion of a generally circular configuration. One or more sharp longitudinal cutting edges are integrally formed with the main body portion and protrude from the main body portion at an angle selected to cause controlled flex and asymmetrical drag on the cutting element, as it is rotated by a rotating string trimmer. This causes a torsional rotation of the free end of the line as it is rotated; so that the main body portion of the cutting element first strikes the object to be cut, followed by contact with the sharp cutting edge. This configuration is selected to cause cleaner cuts of grass and the like, with less shredding of the cut ends of the grass blades. In addition, larger vegetation such as weeds and small stalky shrubs may be efficiently cut without abnormally high wear of the cutting line.
