  • Patent number: 6732797
    Abstract: A method of forming a cementitious plug in a well is disclosed. According to the method, a well is selected for treatment which lacks sufficient formation pressure to cause well fluid to naturally flow to the surface of the well. In addition, a formation penetrated by the well has unobstructed access between it and the surface. Having thus selected a well for treatment, a liquid slurry comprising a cementitious material, whose density is greater than the density of the well fluid, is introduced into the well. The slurry is permitted to drive the well fluid into the formation. Sufficient slurry is added to the well to fill the well to the surface. The slurry is then permitted to set into a hardened mass.

  • Patent number: 6684666
    Abstract: A set of handcuffs having an improved locking mechanism. The critical element of the locking mechanism is the utilization of a locking gear set that replaces the conventional pawl. The teeth in the locking arm are matched to the locking gear set and are always in constant and full contact with the locking gear set. This invention also uses a cam/cylinder locking device that controls the movement of the locking gear set. In the normal cam position the locking gear set will only turn in one direction, thus enabling the locking arm to close. In the second cam position the locking gear set will not turn in either direction. The cam can be rotated, through the use of a cylindrical key, in either directions. Rotation in one direction will select one of two locking positions. Rotation of the cylindrical key in the opposite direction will free locking gear set to rotate in the opposite direction thus disengaging the locking arm.

  • Patent number: 6655097
    Abstract: An apparatus and a method of using the apparatus to temporarily support a utility pole is disclosed. The apparatus is comprised of a plurality of structural elements which are hinged together to form an articulated frame. The frame is adapted to be connected to a pole and caused to conform to the slope or angle of the pole with respect to the ground. The frame is also adapted to conform to the slope of the ground in which the pole is embedded. The articulated frame of this invention finds particular utility in supporting a utility pole installed in ground subject to collapse due to excavation in the vicinity of the pole. In this regard, the frame is useful to obviate the need to temporarily reroute a power line erected in the vicinity of earth removal operations.

  • Patent number: 6564725
    Abstract: This disclosure provides an article of manufacture for supporting a load. The article can be employed to store a load under static conditions for an extended period of time, and can also serve as a platform for supporting the stored load while the load is being lifted from one location and transported to and placed in another location. The article is comprised of a plurality of separate planar elements which are releasably, but rigidly, connected each to the other to facilitate transport, assembly, repair and replacement of the parts. In one aspect, the article is comprised of a load contacting component featuring a structural system comprised of ribs located in one of the said planar elements inserted into and stabilized by slots located in another of the said planar elements. In another aspect, the load contacting component can be releasably attached to another of the said planar elements to form a rackable pallet capable of supporting a load in an open rack drive-through storage system.
