  • Patent number: 12163756
    Abstract: A loading apparatus of the present disclosure may be configured to receive one or more cartridges and assist with loading the one or more cartridges when received by the loading apparatus into a revolver. The loading apparatus may comprise a housing, a follower, a spring, and a release mechanism. The housing may include at least an upper end and a forward upper opening configured to receive therein and dispense therefrom the one or more cartridges. The spring is configured to apply an upward force to the follower towards the upper portion of the housing. The release mechanism may be defined on the housing and be configured to selectively disengage the upward force of the spring from an uppermost cartridge of the one or more cartridges while maintaining the upward force on the follower and any other cartridges of the one or more cartridges when received by the housing.

  • Patent number: 10323783
    Abstract: A system and method are provided for abandoning a tee assembly. The tee assembly comprises a tee member, a plug, and a retention member. The tee member is coupled to a conduit and defines a main passage and a branch passage. The main passage extends into the conduit, and the branch passage extends to the main passage. The plug is slideably disposed in the branch passage and extends at least partially into the main passage. The retention member is slideably disposed in the main passage and configured to interlock with the plug within the main passage. The plug is substantially prevented from sliding out of the branch passage when the plug is interlocked with the retention member.

  • Patent number: 10174874
    Abstract: A pipe fitting configured to be coupled to a pipe, the pipe fitting including a body that is elongate along a central axis that extends in a longitudinal direction, the body including a shell, a stiffener, and a shell-stiffener. The shell includes a shell inner surface that defines a shell through hole that extends through the shell in the longitudinal direction. The stiffener is positioned within the shell through hole, and the stiffener includes a shell outer surface that faces the shell inner surface such that the stiffener outer surface and the shell inner surface cooperate to define a pocket configured to receive the pipe. The shell-stiffener seal member includes a first seal member and a second seal member aligned in a radial direction, which is perpendicular to the longitudinal direction.

  • Patent number: 7175732
    Abstract: Membrane sheeting with preapplied seam tape is formed by applying the seam tape to a preformed sheet along the center of the sheet. A cut is formed through the seam tape and sheeting. This forms two sheets with seam tape along one edge of each of the sheets.

  • Publication number: 20050237258
    Abstract: An antenna assembly includes a common reflector and multiple monopole type antenna elements positioned on a ground plane and fed with a switch assembly. The switch assembly is capable of feeding individual antennas as well as combining multiple antennas for improved radiation pattern coverage. Multiple antenna elements are placed around the common reflector to cover sectors of space around the antenna assembly to provide transmission and reception of radio frequency (RF) signals for mobile communication devices in a wireless network. The ground plane can be grounded or capacitively coupled to an existing circuit board or metal surface, allowing for reduced ground plane dimensions.

  • Publication number: 20050140140
    Abstract: A connector adapted for use with an associated fluid line includes a connector body having a passage dimensioned to receive the associated fluid line and a capturing member supported on said connector body. The capturing member is suitable for retaining the associated fluid line in the passage. A sealing member is disposed within the passage and is suitable for forming a fluid-tight seal between the connector body and the associated fluid line. A stiffening member is disposed within the connector body along the passage, and an indicator is disposed within the connector body and is adapted to indicate that the associated fluid line has been received a predetermined distance into the passage.

  • Publication number: 20050139171
    Abstract: A heat trap assembly for a hot water tank includes a heat trap insert and a sealing member retained by the heat trap insert. The heat trap insert includes a seat having an opening that is dimensioned to be covered by the sealing member when no water is flowing through the assembly. The heat trap insert also includes a plurality of fingers to retain the sealing member when water is flowing through the heat trap assembly.

  • Publication number: 20050022872
    Abstract: A valve operable with an associated fluid delivery system having fluid flow therethrough includes a housing, a valve body and a resetable excess flow valve. The housing has a first passage and the valve body is disposed along the first passage and including a wall at least partially defining a second passage. The excess flow valve is supported along one of the first and second passages. The valve body is displaceable between a first position permitting flow through the second passage and a second position substantially shutting-off fluid flow and resetting the excess flow valve.

  • Publication number: 20040187432
    Abstract: Membrane sheeting with preapplied seam tape is rolled up by applying the seam tape along a first edge and folding a second edge of the membrane on itself so that it merely abuts an inner edge of the seam tape but does not overlap the seam tape. This forms a folded sheet which has a uniform thickness across its entire width. This can then be rolled in the standard manner to form a roll which has a uniform diameter throughout.
