  • Patent number: 6278371
    Abstract: Absorbent pads with theft alarm activator elements concealed from view within each individual pad. These pads are designed for inclusion in a tray with a meat, fish or poultry product. The alarm activator element in each pad may be a strip or wire of magnetic material of suitable magnetic retentivity. In an alternative arrangement, a resonator may be used in conjunction with a magnetic strip which controls its resonant frequency. In the case of meat or poultry product pads, the element is cored into the pad between pluralities of laminated layers of tissue, cellulose, airlaid or composite. The element may be positioned between adjacent pairs of laminated tissues in a composite pad.

  • Patent number: 4586265
    Abstract: A drafting apparatus having a linear edge with first and second wheel means associated with the edge to rotatably move the linear edge across a planar drafting surface and wherein the wheels are of differing diameter so as to have the linear edge move across an arc defined within a circle toward which the linear edge is always pointed. The center of that circle is the vanishing point as conventionally utilized with perspective drawing techniques.

  • Patent number: 4485561
    Abstract: A process for hanging framed articles utilizing a measuring device which has an elongated support with first and second moveable indicators. The process comprises vertically orienting the elongated support along a wall, moving the first indicator to a position corresponding to the desired placement of the top of the framed item, removing the elongated support from the wall and placing the first moveable indicator on the top of the framed item. The second moveable indicator is moved to a position corresponding to the hanging mechanism of the framed item. The elongated support is then again vertically aligned along the wall and the point for the location of a hanging device is located at the position of the second moveable indicator.
