In certain embodiments, a vial adaptor for removing liquid contents from a vial comprises a piercing member and a bag. The bag can be contained within the piercing member such that the bag is introduced to the vial when the vial adaptor is coupled with the vial. In some embodiments, the bag expands within the vial as liquid is removed from the vial via the adaptor, thereby regulating pressure within the vial. In other embodiments, a vial comprises a bag for regulating pressure within the vial as liquid is removed therefrom. In some embodiments, a vial adaptor is coupled with the vial in order to remove the liquid. In some embodiments, as the liquid is removed from the vial via the adaptor, the bag expands within the vial, and in other embodiments, the bag contracts within the vial.

A bleed valve control system for mounting to a support structure adjacent to a fan air plenum within an aircraft includes a bleed valve module, a pneumatic valve controller, and a fan air duct. The bleed valve module includes a pipe, a plurality of bleed valves connected to the pipe, and a plurality of pneumatic actuators connected to the bleed valves. The pneumatic valve controller includes a plurality of electrical control elements and a cooling shroud. The cooling shroud is attached to the pipe and at least partially surrounds the plurality of electrical control elements. The fan air duct connects the cooling shroud to the fan air plenum such that fan air flows through the cooling shroud to cool the plurality of electrical control elements.

Fluid flow control devices comprise a cylindrical body extending along a longitudinal axis and having a sidewall. The cylindrical body has a first channel extending longitudinally along the sidewall and a second channel extending longitudinally along the sidewall. At least a portion of one of the at least one first channel and the at least one second channel extends longitudinally at an oblique angle with respect to the longitudinal axis to form a pattern of channels for improving the flow characteristics of a fluid through the channels.

A device for emitting bubbles in a vehicle wash facility includes a plenum supported with respect to ground. The plenum includes an air inlet with a first area and an air outlet with a second area. The plenum air outlet is in communication with at least one foaming chamber. The foaming chamber includes a generally planar media element disposed therein. The foaming chamber includes a spray jet located therein, which is in communication with a source of chemical. The spray jet configured to emit a chemical onto the generally planar media element. The device also includes a plurality of nozzle portions in communication with the foaming chamber for emitting bubbles therefrom.

In various embodiments, a connector system may include at least two connectors and a collar configured to detachably align the at least two connectors for coupling to a mating collar with at least two mating connectors. The collar may also be configured to at least partially disengage from the at least two connectors to allow movement of the connectors relative to each other. The relative movement may allow the connectors to couple to mating connectors that are in different configurations (than the mating collar configurations). In some embodiments, the connectors and/or mating connectors may include complementary male/female connectors. In some embodiments, the collar/mating collar may circumscribe their respective connectors and/or a perimeter of the other of the collar/mating collar. In some embodiments, the collar/mating collar may include interfacing features.

Disclosed are implementations for efficient purging of substrate carriers (and content held therein) and preventing external contaminants from entering a gas purge apparatus by coupling the gas purge apparatus to a substrate carrier, performing a first gas purging session of an environment of the substrate carrier, receiving a first signal of a first signal type, responsive to receiving the first signal, keeping the gas purge apparatus coupled to the substrate carrier, performing a second gas purging session of the environment of the substrate carrier, receiving a second signal of a second signal type, and, responsive to receiving the second signal, decoupling the purge apparatus from the substrate carrier.

An inline dispersal valve that can be used with or without a base. One embodiment includes a rotatable member that is rotatable from a fluid stream obstructing condition to an out-of-the-way condition to prevent fluid diversion into the dispersal valve. Another embodiment includes a lever handle for quickly setting the amount of fluid being diverted into the inline dispersal valve. Another embodiment includes an indicator that can be viewed from a position above the inline dispersal valve. Another embodiment includes a cap that can be secured or removed without the aid of tools. Another embodiment includes a clip that allows one to disassemble the inline dispersal valve for servicing. Another embodiment includes a dispensing valve that can be reversed and still properly divert fluid into a dispersant chamber. Another embodiment includes an inline dispersal valve with a bleed valve positioned to allow one to bring the air volume in the dispersant chamber to the proper level.

A blood treatment air purging system and method includes a level detector positioned and arranged to detect a low fluid level in a blood circuit indicating a high amount of air in the blood circuit; a blood pump operable with the blood circuit; a venous patient line of the blood circuit; and at least one blood circuit air vent valve, wherein the system and method are configured or programmed to (i) stop the blood pump, (ii) close the venous patient line, and (iii) open the at least one blood circuit air vent valve to atmosphere or a container when the low fluid level is detected, and (iv) run the blood pump to meter air through the at least one blood circuit air vent valve to atmosphere or the container.
