  • Publication number: 20240102361
    Abstract: The present disclosure includes a cleaning system for cleaning clean a tubing, casing, or components of an oil well. In some aspects the cleaning system includes a washing tool having a body configured for insertion into a component of an oil well. The body may include a proximal end and a distal end and define an inlet at the proximal end, a channel in fluid communication with the inlet, and an outlet in fluid communication with the channel. The outlet my extend circumferentially along a perimeter of the body. In some configurations, the washing tool may be configured to clean the component by ejecting fluid in a 360 degree range without movement of the tool.

  • Patent number: 9979068
    Abstract: Disclosed are systems, circuits and methods related to low-loss bypass of a radio-frequency (RF) filter or diplexer. In some embodiments, a switching network circuitry can include a first switch that has an input pole configured to receive a radio-frequency (RF) signal, a pass-through throw configured to be connectable to the input pole to allow routing of the RF signal to an RF component, and at least one dedicated bypass throw configured to be connectable to the input pole and at least one bypass conduction path. The switching network circuitry can further include a second switch that has a pole and a throw, and is connectable between an output of the RF component and the bypass conduction path. Use of the dedicated bypass throw(s) in the first switch allows implementation of low-loss bypass of the filter or diplexer.

  • Patent number: 9624696
    Abstract: An exemplary locking cartridge includes a generally cylindrical housing, first and second plates, and a sliding member. The plates are rotatable with respect to the housing, and at least one of the plates is movable in the axial direction of the housing. The housing and the movable plate include cam surfaces that interact to cause the movable plate to move toward the other plate when the movable plate is rotated. The sliding member is slidingly coupled to one of the plates and operable in a blocked state in which the sliding member resists axial motion of the movable plate, and an unblocked state in which the sliding member does not resist axial motion of the movable plate.

  • Patent number: 9587415
    Abstract: A retention mechanism for retaining a lock cylinder in a lock housing. The retention mechanism includes a control lug, a control pin, and a finger pin. A portion of the control lug is configured to be positioned in a retention recess of the lock housing when the control lug is in an engagement position to prevent the removal of the lock cylinder from the lock housing. With the control lug in the engaged position, at least a portion of the control pin may be biased into a chamber of the control lug to retain the control lug at the engaged position. When the control lug is to be displaced from the engaged position, the finger pin may be lifted to an activation position, such as by a sidebit of a key, wherein the finger pin may removably displace the control pin from at least a portion of the chamber.

  • Patent number: 9447608
    Abstract: A locking cartridge including a housing, first and second plates rotatably mounted in the housing, a blocking member, and a movable member. The cartridge also includes a cam interface which urges the first plate toward the second plate when the plates are rotated. The blocking member is configured to move among a blocking position and an unblocking position in response to engagement with a first cut on a key. When in the blocking position, the blocking member blocks the first plate from moving toward the second plate. With the second plate blocked from moving toward the first plate, the cam interface prevents rotation of the first plate. The movable member is configured to move among a first position and a second position in response to engagement with a second cut on the key. In certain embodiments, the movable member may be a control pin or a second blocking member.

  • Patent number: 9447605
    Abstract: A plug assembly for a lock includes a generally cylindrical plug body that defines a keyway and a generally cylindrical plug housing that rotatably receives the plug body. A plurality of blocking members are housed in the plug body and are movable into the keyway upon rotation of the plug body relative to the plug housing to obstruct the keyway. A key can be provided that is positionable into the keyway, and the blade of the key defines receptacles for receiving the blocking members when the plug body is rotated so that the lock can be unlocked. However, the blocking members prevent rotation of the plug body when a picking tool or unauthorized key is inserted in the keyway since either the blocking members cannot move into the keyway and remain engaged to the plug housing due to the object in the keyway, or obstruct the keyway and prevent insertion of the picking tool.

  • Patent number: 7051562
    Abstract: A retainer clip is used for retaining a lock plug within a bore of a lock housing. The retainer clip includes a generally arcuate body disposeable about the plug outer surface and having a radial retention surface positionable generally against a housing end surface so as to prevent axial displacement of the plug along the bore. Two projections are each disposed proximal to a separate end of the body, each projection being disposeable within a separate plug opening when the body is disposed on the plug to retain the clip engaged therewith. The clip body has a hinge, a first arm portion extending between the hinge and one free end and a second arm portion extending between the hinge and the other end. The hinge is configured so that the two arm portions are deflectable generally about the hinge to move with respect to each other during installation and removal.

  • Patent number: 6948627
    Abstract: In baseball and softball, as well as other sports, equipment such as helmets, caps, and ball gloves are worn by the players, but not necessarily throughout the entire duration of a game. When not being worn, this equipment should be organized by hanging it up. However, hooks for hanging equipment are not universally available at all ball diamonds and other sports fields. A scissor-folding hanger made of light material such as PVC pipe and made to hang on a fence provides the needed storage space. Such a hanger is light and folds into a very small package, enhancing its portability. The strength of the rack can be varied by using larger or smaller diameter pipe for its construction. The scissor-folding sports-gear hanger is a flexible solution to the storage needs on the sports-field.
