Abstract: A torque limiting coupling assembly shields a valve actuator from abnormally high levels of torque. In normal operation, an actuator coupling transfers a driving torque from an actuator coupling to a valve shaft coupling and the valve shaft coupling engenders a shaft torque on a shaft of a valve. In torque actuated operation, when a counter torque applied to the shaft coupling exceeds a threshold value, the actuator coupling freely rotates relative to the valve shaft coupling and the driving torque is transferred to a biasing element of the torque limiting coupling assembly rather than to the valve shaft coupling, thereby shielding the valve or the actuator from high levels of torque.

Abstract: A retention clip secures a valve shaft adapter collar to a valve actuator. The retention clip includes a central bar having opposing arms extending therefrom. Each arm includes a resilient spring clip junction attached to the central bar, a lug coupled to the resilient spring clip for receiving pliers, and an end extending from the lug and configured for insertion through a hole in the valve shaft adapter collar into a pocket of the valve actuator for retaining the valve shaft adapter collar therein. The pliers can be used to compress and consequently retract the ends into the holes to disassociate the valve shaft adapter collar from the valve actuator and/or insert the valve shaft adapter collar into the valve actuator.

Abstract: Methods and systems for enriching an information system containing information about companies with additional competitor information. The information system, which could be a database, a knowledge base, or a knowledge graph, is assumed to contain information about a plurality of single companies, the information comprising data such as industry codes, competitors, and possibly also keywords for each company. The disclosed methods determine new competitor pairs by combining (i) the generation of new competitor candidate pairs by inference from existing competitors and other company-specific knowledge with (ii) the validation of such competitor candidates pairs by checking for joint occurrence in documents of a document repository.
