  • Patent number: 8408355
    Abstract: A downhole tool for subsurface disposal is provided. The tool comprises an elongated tool body, an enclosure attached to an exterior surface of the tool body. The enclosure comprises at least one transducer disposed at an angle with respect to a longitudinal axis of the enclosure, and an electronics board coupled to and disposed adjacent to the at least one transducer. The enclosure also defines an internal cavity, and the internal cavity contains a fluid for insulating the at least one transducer from a downhole environment. The fluid is in direct contact with the at least one transducer and the electronics board.

  • Patent number: 8256565
    Abstract: An enclosure for housing a transducer and electronics for disposal on a downhole tool. A transducer is disposed at an angle with respect to a longitudinal axis of the enclosure, wherein the enclosure contains a fluid surrounding the transducer. Enclosures also include transducers linked to motor means for selective rotation of the transducers within the enclosure. Enclosures with transducer arrays for phased or targeted signal transmission/detection.

  • Patent number: 7913806
    Abstract: A measurement package for disposal on an apparatus such as a downhole tool or a tool like device. The measurement package including an enclosure, a first acoustic transducer housed within the enclosure, a second acoustic transducer housed within the enclosure and electronics housed within the enclosure that is in communication with the first and second transducers. Further, an acoustic transmitter and receivers can be disposed at an angle with respect to a longitudinal axis of the enclosure. The enclosure can contain attenuative material surrounding the transmitter and receivers, and electronics for controlling the transmitter and receivers and communicating with the downhole tool.

  • Patent number: 5178576
    Abstract: A pair of platform devices used for interaction with a flexible coil spring toy have a plurality of flat step-like surfaces separated vertically and horizontally corresponding to the periodic step-walking motion of the flexible coil spring toy. The platform devices are manipulated in an alternating sequence in cooperation with the motion of the flexible coil spring toy to give the appearance that the toy is walking down a set of stairs. In the preferred embodiment, the platform devices have a handle and are held and manipulated by a human operator. The spring momentum transfers the coils of the spring from one surface of the device to the next lowermost surface of the device as the spring's adjacent coils successively sweep through the path of an arc.

  • Patent number: 4881738
    Abstract: A manipulative amusement device that includes upper and lower plates parallel to and in coaxial alignment with and rotatable relative to each other, each plate having a pair of spaced collar pieces disposed on opposite sides of a plurality of openings disposed in the periphery thereof to define a plurality of coaxially disposed spaced pairs of collar members, and a plurality of cylinder assemblies each formed about a respective longitudinal axis and comprised of an even number of cylinder segments with each cylinder assembly having opposing ends adapted for being rotatably received by the pair of spaced coaxially aligned collar members for permitting rotation of the cylinder assemblies.

  • Patent number: 4708345
    Abstract: An amusement device for use in providing a manipulative puzzle, word games, games of chance, scoring games, or the like. Upper and lower parallel plates are planarly rotatable about a vertical axis. A plurality of cylinder assemblies is carried by the plates disposed on the outer periphery such that their longitudinal axes intersect to define a regular polygon parallel to the plates. Means are provided for maintaining spatial position of the upper one-half of each cylinder assembly relative to the upper plate, and the lower one-half of each cylinder assembly relative to the lower plate as the plates are rotated in opposing directions. When the plates are rotated such that the upper and lower cylinder halves combine to define the cylinder assemblies, each such assembly is further rotatable about its longitudinal axis. Each cylinder is comprised of sections each preferably having an identifier on its outer surface such as a different color or the like.

  • Patent number: 4583602
    Abstract: An improved small diameter, high density shaped charge perforating apparatus is provided. The perforating apparatus includes an elongated carrier member having a plurality of shaped charge receiving stations spirally located therealong. The anterior and dorsal sections of the shaped charges extend outside the outer diameter of the carrier member and a length of helically wound detonator cord passes through an axial aperture in the dorsal section to retain the shaped charges in the carrier member. An alignment member is connected to one end of the carrier member to prevent rotational movement of the carrier member within the gun body and aligns the axis of perforation for each shaped charge with spotfaces on recesses in the periphery of the gun body.

  • Patent number: 4484639
    Abstract: Method and apparatus for completing sursurface formations traversed by a borehole. A perforating gun and a firing head assembly are run into the borehole on the end of a tubing string. A percussion firing assembly subsequently is lowered through the tubing string and latches into the firing head assembly. To initiate the firing system an impact member is dropped through the tubing string. Should ignition fail to occur the percussion firing assembly can be detached and removed from the borehole. Additional percussion firing assemblies can be lowered into engagement with and removed from the firing head assembly as desired. Further, an electrical firing assembly can be lowered through the tubing string into engagement with the firing head assembly and an electrical control signal used to detonate the perforating gun.
