Abstract: A kickover tool for retrieving a used gas lift valve installed within a gas lift mandrel connected along a wellbore tubular string and installing a new gas lift valve within the gas lift mandrel. The kickover tool may include a housing, a first holder configured to hold the used gas lift valve, a first displacement mechanism operable to move the first holder between a retracted first holder position in which the first holder is adjacent the housing and an extended first holder position in which the first holder is spaced away from the housing, a second holder configured to hold the new gas lift valve, and a second displacement mechanism operable to move the second holder between a retracted second holder position in which the second holder is adjacent the housing and an extended second holder position in which the second holder is spaced away from the housing.

Abstract: Provided is an increased capacity firearm ammunition magazine with a metallic body. The body is dimensioned to compatibly replace a (OEM) polymer or polymer over metal single stack magazine. The body has walls with exterior dimensions compatibly matching those of the OEM magazine and that are thinner than those of the OEM magazine. The thinner walls allow an at least partially laterally offset arrangement of cartridges therein. A longitudinal exterior ridge extends along a forward wall of the body and is configured from the metallic body walls and sized to compensate for forward-to-aft dimensioning difference compared to that of the OEM magazine.

Abstract: Training accessories and methods for improving athletic techniques, such as, for example, tackling form for football. A display can be coupled to a piece of athletic equipment, such as a tackling dummy, and the display depicts a symbol at a time at which a player is or is about to interact with the equipment or perform a movement or action. An input is provided of the player's identification of the depicted symbol and compared to the symbol that was actually depicted. The player's correct identification of the depicted symbol can indicate that the player performed the movement or action, or the interaction with the equipment, with appropriate form. A player's failure to correctly identify the depicted symbol can indicate to a coach that the player may need further instruction on proper technique or form with which the movement or action, or the interaction with the equipment, should be performed.

Abstract: A downhole tool for connecting with a conveyance line. The downhole tool may be or comprise a connector assembly operable to connect to the line. The connector assembly may include a first connector, a second connector, a latching member, and a rotatable member. The first connector and the second connector may be configured to accommodate the line therebetween. The latching member may be latched against the first connector. The rotatable member may be operatively connected with the latching member such that rotation of the rotatable member with respect to the latching member causes relative axial movement between the latching member and the rotatable member thereby forcing the first connector and the second connector toward each other to compress the line therebetween to therefore connect the connector assembly to the line.

Abstract: A wheel assembly configured to detachably connect to a downhole tool to thereby reduce friction between the downhole tool and a sidewall of a wellbore through which the downhole tool is conveyed. The wheel assembly may include an axle configured to contact a sidewall of the downhole tool, wherein the axle comprises a bore extending therethrough, a wheel rotatably connected to the axle such that the wheel extends around at least a portion of the axle and the bore, and a fastener configured to be disposed at least partially within the bore and extend out of the bore into the sidewall of the downhole tool to detachably connect the axle to the downhole tool.
