  • Patent number: 11078052
    Abstract: Adaptable clevis kits may be used when calibrating crane scales, dynamometers and tension links for force calibration laboratories. An adaptable clevis kit may include one set of devises (one pair) with multiple sets of pins with different diameters. With this kit, the same set of devises may be used for calibrating several models of instruments. For each instrument, the pin may be designed with the same diameter that the manufacturer originally made the equipment and reported on its specification sheets. With this method, the error due to difference in pin sizes is eliminated, and the laboratory may save the cost of purchasing dozens of different devises. The adaptable clevis kits may also be provided with a guiding table that help the user find the right size pin for the instrument being calibrated based on the manufacturer's original design.

  • Patent number: 8418434
    Abstract: A fashion accessory featuring a plurality of units connected together to form a continuous chain having a first end and a second end. The first end and second end are connected together via a locking means. Each unit is a loop. The units each occupy a folded configuration. In the folded configuration, the unit is folded in half to form a first top arc and a second top arc that are positioned next to each other, and a first bottom hook and a second bottom hook that are positioned across from each other. Adjacent units are fed through both bottom hooks and subsequently moved to occupy the folded configuration.

  • Publication number: 20130081372
    Abstract: A device for recovery of physical objects includes a chain having two ends and a retriever attached to one of the ends. The retriever is configured to locate the object to be recovered and to grasp and retrieve that object once located. The retriever includes transducers that detect acoustic frequencies propagating in a fluid medium. Independent transponders, which can be deployed from the retriever; are provided for deployment in an area to be searched. Each transponder emits a predetermined acoustic frequency that is detectable by the transducers. The transducers signal movement of the recovery device for retrieval of the object.
