Some embodiments disclosed herein related to a device for transferring precise amounts of fluid from at least one source container to a at least one target container. In some embodiments, the fluid is first transferred from the source container (e.g., a vial) through a connector to an intermediate measuring container (e.g., a syringe). In some embodiments air can pass through an air inlet and enter the vial to compensate for the volume of fluid withdrawn from the vial. An air check valve or a bag or a filter can prevent the fluid from escaping through the air inlet. The precisely measured amount of fluid can then be transferred from the intermediate measuring container to the target container (e.g., an IV bag). In some embodiments the connector can include a source check valve and a target check valve to direct fluid first from the source container to the intermediate measuring container and then from the intermediate measuring container to the target container. Some embodiments of the device can include a motor and a controller for automatically actuating a plunger of the syringe to transfer the desired amount of fluid.

A method for sensing and launching pipeline pigs into a pipeline. The method includes pressurizing a pressure accumulator in a pig launching system that includes a pig chamber, a plurality of pigs, a launch tube, and the pressure accumulator.

A lint roller assembly is disclosed for rotatably supporting a tubular and cylindrical adhesive lint remover roller. The assembly includes a pair of elongated housing parts which are substantially identical to each other. Each housing part includes an elongated handle section and a semi-cylindrical lint roller support section longitudinally adjacent the handle section. The lint roller support section has an outer diameter less than the diameter of the adhesive roller. The housing parts are secured together in a facing relationship by registering pins and sockets formed on the housing parts. In doing so, the lint roller support sections form a cylindrical lint roller support for the adhesive roller while the handle sections abut against each other to form a handle.

The pig launcher is installed subsea by coupling it to a launcher manifold. The launcher manifold is installed substantially permanently subsea as a part of a pipeline. The pig launcher includes a dual bore collet connector for coupling to the launcher manifold, and a rotary storage magazine for storing the pigs. The launcher manifold can be manufactured, for example, as part of an inline lateral tie-in sled or as part of a pipeline end manifold (PLEM). A branch connection from the pipeline to the pig launcher is provided in the launcher manifold via a piggable Y connection to a dual bore collet connector male hub. The pig launcher is landed and latched to the launcher manifold to complete the pig launching system. A closure valve between the Y connection and the hub prevents a pressure loss when the pig launcher is not installed, and the closure valve is opened to permit passage of the pigs during launching. A throttle valve upstream of the Y connection allows the pipeline pressure to be dropped downstream so that a pig can be launched using upstream pressure. During launching, a kicker valve is opened to bypass the throttle valve and direct the higher upstream pressure through the secondary bore of the dual bore collet connector and into the rotary magazine.

Systems, devices, and methods are disclosed for the cleaning of an endotracheal tube while a patient is being supported by a ventilator connected to the endotracheal tube. According to some embodiments, a mechanically-actuated non-inflatable cleaning device for scraping debris (e.g., biofilm) from an interior wall of an endotracheal tube is provided. In one embodiment, the cleaning device comprises an elongated member having a proximal end and a distal end and a mechanically-expandable scaffold positioned along the distal end of the elongated member. In one embodiment, the mechanically-expandable scaffold comprises one or more removal members configured to engage an interior surface of an endotracheal tube when the scaffold is in a radially-expanded position and to remove debris from the interior surface of the endotracheal tube when the device is withdrawn from the endotracheal tube.

The seal assembly is disclosed for use with a valve having a trim cage with an inner surface extending along in axis and a plug sized to fit inside the trim cage inner surface, wherein the plug is adapted to move along the axis thereof. A seal ring is attached to an upstream portion of the cage to effectuate a seal with the plug. The plug is equipped with a wiper seal that cleans or otherwise removes debris from the seating surface of the seal ring, an interior surface of the seal ring and an interior surface of the cage during both the opening and the closing of the valve. Thus, the valve is self-cleaning. Further, the wiper seal delays throttling action through the valve until the plug has moved a substantial distance away from the seating surface of the seal ring which reduces high pressure abrasive flow against the seating surface of the seal ring to reduce wear on the trim set.

The invention outlined in the disclosure is an adjustable wire brush tool for cleaning either the inside or the outside end of a copper pipe or fitting in preparation for soldering the parts together. The tool includes a hollow cylindrical section with a first wire brush on the interior surface of the section. Attached at one end of the cylindrical section is a slightly smaller cylindrical section sized to hold a second cylindrical twisted steel brush having a hexagonal shaft that extends from the smaller section, opposite the larger cylindrical section. The twisted steel brush and attached shaft can be moved to extend the twisted brush beyond the open end of the larger cylindrical section, for insertion into a fitting to clean the fitting interior surface by attaching a power drill to the shaft and rotating the twisted steel brush attached thereto. To clean the outside of a pipe, the twist brush is retracted into the smaller section and secured to that section with an engaging means. The pipe is inserted into the larger section, and the drill is activated to rotate the shaft and attached larger section to clean the pipe outer surface. The tool overcomes the need for separate tools to perform each task and requires but one drill to perform either task as needed. The tool is sized to handle a particular diameter of pipe and fitting, with sizes ranging from one quarter inch to several inches.
