Abstract: Aspects of the present disclosure relate generally to application ecosystems and, more particularly, to navigational and executional operations in an application ecosystem. In embodiments, a method includes: receiving, by a computing device, a natural language request input by a user to perform a task in an application ecosystem of a plurality of applications; determining, by the computing device, an actionable task from the natural language request to perform in the application ecosystem; generating, by the computing device, a user interface screen to perform the task with input parameters required to perform the task populated in elements of the user interface screen derived from the natural language request; and performing the task with the input parameters required in the application ecosystem of the plurality of applications.

Abstract: A fluid dispenser comprises an applicator portion, a handle portion, a pump, a valve, a first piston, a first resilient device, a second piston, and a second resilient device. The handle portion defines a pump support section and a reservoir. The pump support section includes the pump and a premeasure cavity. The valve is moveable between a normally closed position and an open position. The first piston moves in the reservoir and has the first resilient device biasing the piston for pushing fluid from the reservoir to move the valve to its open position so that fluid flows from the reservoir to the premeasure cavity to fill the premeasure cavity with a first premeasured charge of fluid. The valve moves back to its normally closed position after the premeasure cavity is filled. The second piston moves in one direction in the premeasure cavity and pushes the first premeasured charge of fluid from the premeasure cavity to the applicator portion.

Abstract: A housing is shaped to mate with a large turret or engine type lathe tailstock. A rack and pinion assembly is mounted within the housing with a chuck attached to an end of the rack. An adjustable hand lever is attached to the pinion and allows the operator to advance the rack and chuck with precision control. The attachment virtually eliminates drill bit breakage.
