Abstract: Particular embodiments may receive and log information related to one or more events occurring on one or more client computing devices associated with a user. An event may comprise a restriction of a user action on a social-networking system, the restriction comprising the social-networking system blocking the user from performing the user action. An event may comprise a login issue associated with logging in to the social-networking system. An event may comprise a system or device error. System errors may comprise events originating from a third-party system. For each event, an indication of the event and at least one user-activatable reference may be provided for display to the user. A control action may then be determined for the event in response to a user selection of the user-activatable reference. An interface may provide third parties with a view of a user's events as well as functionality to effect control actions.

Abstract: A hollow fiber membrane gas separation apparatus of a compact design suitable for separation and purification of gases is disclosed. The apparatus comprises an outer housing that consists of a detachable bowl and a head closure, and a removable hollow fiber membrane cartridge positioned therein. The cartridge contains a concentric tubular inner core member and is surrounded by a shell and at least one end closure. The cartridge is attached by its first axial end in a sealed and removable manner to a gas flow conduit positioned coaxially in the housing closure wherein the conduit is in fluid communication with a gas inlet or product gas outlet port formed in the housing head closure and by its second axial end to a waste gas exit port in the bowl. The feed gas inlet port and the product gas outlet port in the head closure are spaced in a straight line for a short overall distance providing for a linear connection with other components of a gas separation system, which is a preferred system component packaging.

Abstract: An integral hollow fiber membrane gas purification apparatus is disclosed. The apparatus comprises one or more filtration elements and a hollow fiber membrane cartridge placed coaxially in a common housing. In some embodiments, the filtration elements are omitted and the hollow fiber membrane cartridge is employed as a combined gas separation/filtration device. The apparatus of this invention is particularly useful for conditioning compressed air that includes the removal of both suspended matter and water vapor.

Abstract: A hollow fiber membrane gas separation apparatus of a compact design suitable for separation and purification of gases is disclosed. The apparatus comprises an outer housing that consists of a detachable bowl and a head closure, and a removable hollow fiber membrane cartridge positioned therein. The cartridge contains several concentric separation zones and provides for efficient countercurrent flow configuration between the feed gas on the shell side and the permeate sweep gas on the lumen side of the hollow fiber membranes.
