Abstract: A gas capture system is configured to purify gas streams. The gas capture system includes a first capture system including a plurality of first chambers interconnected by a first path. Each first chamber includes a first adsorbent. The gas capture system further includes a second capture system including a plurality of second chambers interconnected by a second path. Each second chamber includes a second adsorbent. The gas capture system further includes a third path connecting each first chamber to the second path such that a first output of the first capture system is input into the second capture system. The gas capture system further includes a fourth path connecting each second chamber to the first path such that a second output of the second capture system is input into the first capture system.

Abstract: Methods of making an aerosol container having an open neck at the top and a closed end bottom longitudinally spaced therefrom. The container has a valve cup and bag. The valve cup and bag are integral. The valve cup is attachable to the neck in sealing relationship. This arrangement provides for propellant to be disposed intermediate the container and bag. Product can be disposed in the bag for selective dispensing by a user actuated valve.

Abstract: A screening apparatus includes a vibrating screen assembly that includes a screen and a vibrating mechanism operable on the screen to cause vibration of the screen, the screen having a feed end and a discharge end. At least one shield member is positioned on the screen and is configured to cover part of the screen between the feed end of the screen and a position intermediate the feed and discharge ends of the screen, such that particulate material for screening by the screen can be fed on to the, or each, shield member, the, or each shield member being positioned on the screen so that a vibrational pattern of the screen is imparted to the shield member. An adjustment mechanism is operatively engaged with the, or each, shield member to adjust a position of a discharge end of the, or each, shield member relative to the discharge end of the screen.

Abstract: The present invention relates to microfluidic devices that include a reliable seal between a substrate of the device and a fluid transport mechanism. The devices of the invention include at least one internal channel, and at least one port in fluid communication with the channel. A seal is associated with the port and is configured to receive a fluid transport mechanism. The seal is formed from an elastomeric material that is compatible for use with fluorinated oil and resists flaking and degradation.
