Abstract: Techniques for entity engagement are disclosed. An onboarding request is received from an interested entity and a first profile is generated for the interested entity. The onboarding of interested entity is verified and upon successful verification, the first profile is stored in an immutable form on a decentralized authentication framework. Further, an engagement request is received, from at least one of the interested entity and the entity of interest, to initiate a profile engagement between the interested entity and the entity of interest. The engagement request is authenticated to determine the credibility of the engagement request. Upon successful authentication of the engagement request, the first profile and the second profile is retrieved from the decentralized authentication framework. Based on an approval received from at least one of the interested entity and the entity of interest, engagement is initiated between the interested entity and the entity of interest.

Abstract: In some examples, a moveable member including multiple tools is moveable relative to a fixed member to position a selected tool for performing an operation. A first connector half may be included on the fixed member for connecting to one of a plurality of second connector halves included on the moveable member. Movement of the moveable member to position the selected tool for performing the operation moves a respective second connector half associated with the selected tool into connection with the first connector half. In addition, a respective nozzle assembly may be associated with each tool. The respective nozzle assembly may receive multiple fluids including at least one fluid received through the connection between the connector halves. The nozzle assembly includes an inner nozzle that outputs a gas and an annular outer nozzle that outputs a machining liquid to generate a mixture to direct toward a tool-workpiece interface.

Abstract: An atomizing cutting fluid system. The system includes a common chamber terminating in a shaped droplet nozzle and including a nozzle section immediately behind the shaped droplet nozzle. An atomizer creates spray directly within the common chamber behind the nozzle section. A cutting fluid supply line provides cutting fluid to the atomizer. A high velocity gas nozzle within the nozzle section and behind the droplet nozzle is configured to provide a high velocity gas to entrain the flow of droplets. The nozzle section and droplet nozzle are configured to produce a fully developed droplets-gas flow at a predetermined distance from the droplet nozzle. In a cutting system, the spray system provides a uniform film for a macro or micro cutting operation at sufficient flow rates.
