Clutch mechanism, particularly for looms. The mechanism has a housing, in which a pair of opposed electromagnets are stationarily mounted, between which there is arranged a friction disc mounted axially displaceably on a driven shaft. A rotor, fixedly connected to a control shaft disposed coaxially of the driven shaft, is disposed between one electromagnet and the friction disc for selective driving engagement therewith.
摘要:
A loom having a means for automatically unweaving the weft upon the occurrence of a weaving fault, thereby reducing the labor needed to overcome such weaving fault and thus increasing the efficiency of the loom. The apparatus includes a device for the selective prevention of the weft from entering the shed of the loom, said device being mounted on the loom between the weft supply and the weft-entering end of the shed. The invention may be applied to looms wherein measured lengths of weft are inserted mechanically into the shed, or to jet looms, wherein measured lengths of weft are inserted by jets of inserting fluid such as air or water into the shed of the loom.

An improved industrial automation system and communication system for implementation therein, and related methods of operation, are described herein. In at least some embodiments, the improved communication system allows communication in the form of messages between modules in different control or enterprise domains. Further, in at least some embodiments, such communications are achieved by providing a communication system including a manufacturing service bus having two internal service busses with a bridge between the internal busses. Also, in at least some embodiments, a methodology of synchronous messaging is employed.

The subject invention facilitates alert notification in an industrial environment. The systems and methods enable subscribing devices, such as hosts, to receive events and/or alarms associated with industrial controllers. In addition, a subscribed component can unsubscribe, refresh notification related information, and/or acknowledge a notification. The foregoing can be achieved through a set of objects (e.g., notify objects) that implement a notification and dynamic subscription process. A host system can instantiate an associated notify object, subscribe to an event, and be notified about the event. The invention enables multiple hosts to subscribe to the same event, allows each host to select events of interest, and enables the events to be queued if the events occur faster than can be sent. In one aspect of the invention, the systems and methods can be utilized with an event and alarm infrastructure that is applicable on a Control and Information Protocol (CIP).

摘要:
Systems and methods that dynamically generates alarms in real time are disclosed. An interface component receives instructions for generating alarms. A builder component dynamically creates alarms in real time based on instructions received and information stored on a data repository. The information comprises at least one or more of user roles, language spreadsheet and device characteristics. The system can further comprise a publisher component that packages alarms for delivery to web servers and/or another network. A proxy component for implementing the subject invention with legacy controllers is also disclosed.

摘要:
An industrial field device comprises an alarm generator component that creates an alarm relating to the industrial field device and a buffering component that selectively caches the alarm within a data repository. The field device can be an industrial controller or a network infrastructure device. The alarm created by the alarm generator component can be customized according to user information, including user preferences.
摘要:
An alarm generation system within an industrial automation environment comprises a packaging component that packages contextual data together with an alarm. A provision component relays the packaged contextual data and the alarm to an appropriate device. Thus, customized alarms can be provided for certain recipients given particular situations.
