  • Patent number: 4832387
    Abstract: A padlock type security seal and method of making same including a U-shaped shackle, a pair of reversely bent end portions, and a body portion having a pair of chambers for receiving the bent end portions. The chambers each have a locking groove therein for receiving the bent end portions. The seal elements are designed from two molded pieces, an insert and a body. The relative dimensions of the chambers, the shackle, and the locking grooves are chosen to prevent picking.

  • Patent number: 4815698
    Abstract: A hard seated globe valve assembly for use in servicing high and low temperature fluids. The valve includes a moveable stem attached at one end to a tapered plug of hard material. An equally hard seat having a tapered surface is mounted for mating engagement with the plug when the valve is closed. The seat is located in a partition that separates the globe-shaped body into two chambers having fluid inlet-outlet orifices. An annular ring is mounted between the bearing end of the stem and the plug so that the plug is resiliently engaged in the seat when the valve is closed. It has been found that hard seated valves tend to be difficult to open or lose their sealing abilities when servicing extreme temperature fluids due to the expansion and contraction when the valve is heated and cooled. The resilience of the annular ring prevents this problem by permitting the plug to adjust during expansion and contraction, thus making it easier to open the valve after cooling and precluding loss of sealing during heating.

  • Patent number: 4811977
    Abstract: A security seal having a tag attached to a flat strap at the central portion by a pair of flexible members. The seal is adapted for sealing a box structure or container having a strap in one surface thereof and a hasp attached to the container. The tag extends upwardly so as to be visible against the surface of the hasp and container. Formed in the label and the tag surface, such as by stamping or the like, are a plurality of circular scores randomly positioned. The random positioning may be recorded to provide a means for verification. Any attempt to remove the label from the tag will result in destruction of the label.

  • Patent number: 4793644
    Abstract: A security seal having a plastic body including three elongated parallel chambers. Mating with the body is a U-shaped resilient shackle having a pair of legs each having a reversely bent end portion terminating in a sharp edge for insertion in two of the chambers. The third chamber in the body contains a frangible ampule containing a liquid dye. When used to seal a structure, the shackle is threaded through the structure, and the legs are inserted into the chambers. The sharp edges of the reversely bent end portions are flexed into tight engagement with the interior walls of the chambers.

  • Patent number: 4775175
    Abstract: A security seal having a plastic body including three elongated parallel chambers. Mating with the body is a U-shaped resilient shackle having a pair of legs each having a reversely bent end portion terminating in a sharp edge for insertion in two of the chambers. The third chamber in the body contains a frangible ampule containing a colorless liquid. A solid substance that combines with the liquid to create a third substance with a bright hue is stored in the third chamber and/or is coated on selected portions of the seal. When used to seal a structure, the shackle is threaded through the structure, and the legs are inserted into the chambers. The sharp edges of the reversely bent end portions are flexed into tight engagement with the interior walls of the chambers.
