The hose may be fluidly connected to the rotary union. The sleeve may encircle the hose and extend from the spindle plug to a stator of the rotary union. The sleeve cooperates with the spindle plug to limit rotation of the stator and the hose.

Abstract: A method for detecting a leak in a pressure vessel of a system including a plurality of pressure vessels in fluid communication with a common header comprises: reducing a fluid pressure in the common header to a first predetermined value below an operating pressure of the plurality of pressure vessels; gradually adding fluid to the common header at a first flow rate to increase the fluid pressure in the common header from the first predetermined value; monitoring, after gradually adding the fluid to the common header, the fluid pressure in the common header; and determining, based on the fluid pressure in the common header after gradually adding the fluid to the common header, a leak in at least one pressure vessel of the plurality of pressure vessels.

Abstract: A pneumatic control system includes a manifold that defines: a channel for conveying a fluid, a discharge port, a drain port, and an expansion chamber defining a chamber axis. The discharge port defines a flow axis extending between a first end and second end and a receiving region at the second end. The pneumatic control system also includes a filter assembly with a filter member disposed in the expansion chamber, and an actuator configured to selectively control fluid communication between the channel and the discharge port. The chamber axis is substantially coplanar with the flow axis. A filter cap assembly includes a filter cap body enclosing an end of the expansion chamber and selectively removable from the manifold to provide access to the filter assembly. A purge valve body is configured to selectively control fluid flow between the expansion chamber and the drain port.

Abstract: A connection arrangement for a tire inflation system. The connection arrangement includes a rotary union and a hose assembly. A main body of the hose assembly is insertable into and removeable from a receptacle cavity of the rotary union when in a first rotational position. A locking protrusion of the hose assembly is received in the locking opening of the rotary union to secure the main body to the rotary union when in the second rotational position.

Abstract: Data is obtained from a data stream managed by a data stream service prior to expiration of a data retention time. The data is archived to a data store distinct from the data stream service (e.g., in a full or compacted mode). Access to the archived data is provided via a proxy that intercepts requests directed to the streaming service. For example, the proxy or a redirect utility for the proxy may intercept a query, and for data specified in the query that is past the retention expiration time, the data is retrieved from the data store. For data specified in the query that has not yet expired, the data is retrieved from the data stream service. In either case, the system responds to the query with the retrieved data according to the access interface of the data stream service (e.g., injecting the retrieved data into a data stream).

Abstract: A distributed system hosts a plurality of programming interfaces managed according to a hierarchy of security policies. In response to receiving a request from a client to invoke one of the programming interfaces, the system determines whether the client is authorized to call the programming interface by mapping from an attribute of the client to a location in the hierarchy. The system calls the interface in response to determining that the client is authorized to call programming interfaces associated with the location. The programming interface implements the security policy that corresponds to the location.
