Described herein is a clamp for repairing a site of at least one damaged nozzle on a pipe for carrying liquid, such as a sparger nozzle in a header pipe in a boiling water reactor of a nuclear power plant. The clamp in general includes a housing configured for mounting over the site on a surface the pipe, wherein the housing has a front, sides, top, and back. The housing may include an opening, or the clamp may include an orifice plate having an opening and being positioned on the front side of the housing such that liquid exiting the pipe flows through one or both the opening in the housing and opening in the orifice plate. The clamp also includes a bottom surface which, together with the housing and orifice plate, when included, defines an interior chamber. The bottom plate has an opening for alignment, upon installation, with the site, and at least one member, for example, wedges for securing one of the damaged nozzle or support rings for stabilizing a replacement nozzle in position within the housing.

A coded cartridge holder for use with a drug delivery device is provided. The cartridge holder includes a fastener that becomes operative based in part on a length of a cartridge or a diameter of the cartridge. In one embodiment, the cartridge holder is coupled to the drug delivery device. The cartridge holder comprises a first blocking feature. The drug delivery device includes a cartridge detector comprising a second blocking feature. This feature may be a pin, for engagement with the first blocking feature of the cartridge holder when the cartridge acts on the cartridge detector. The cartridge holder may further include a fastening mechanism configured to fasten the cartridge holder to the drug delivery device only when the second blocking feature engages the first blocking feature.

A rapid-connect coupler includes a coupler body configured to convey a fluid; a coupling head at a first end of and communicating with the coupler body, the coupling head configured to transition between a coupled configuration and a de-coupled configuration. The coupler may further include a stop apparatus configured to allow the coupling head to transition from the de-coupled configuration to the coupled configuration without obstruction, and the stop apparatus may be configured to provide a hard-stop as the coupling head transitions from the coupled configuration to the de-coupled configuration.

A tubular scoop that may be utilized with various assemblies for sampling fluid in a pipeline. The scoop has a bend with a bend radius that is from two to four times the diameter of the scoop. The scoop defines a scoop face that is parallel to an axis of the tubular of the scoop. The scoop is mountable with a threaded connection that seals around the tubular. An additional seal with a compression nut allows orientation of the scoop within the pipeline whereupon the scoop orientation is fixed by tightening the compression nut.

Seal assemblies for use with fluid valves are described. An example apparatus includes a cage; a plug including a seal gland; and means for sealingly engaging an inner surface of the cage at least partially positioned in the seal gland and including a first portion and a second portion, in response to a fluid acting on the first portion in a first direction, the first portion to engage, outwardly urge, and splay the second portion to sealingly engage the cage, in response to the fluid acting in a second direction, the second portion to deter the fluid from acting on the first portion, the first direction opposite the second direction.
