Abstract:

A ball return system for returning balls shot at a target to a user of the ball return system includes an ejector adapted to accelerate balls out of the ball return system toward a target destination. The ball return system also includes a mast disposed on a base on which the ejector is disposed. The ball return system further includes a collapsible net support adapted to transition between a collapsed state and an expanded state. The collapsible net support is connected to the mast by a joint that enables the collapsible net support to transition between: a first orientation in which a length of the collapsible net support is aligned with a length of the mast, and a second orientation in which the collapsible support net is stacked on top of the ejector.

Abstract:

A downhole motor may include a power section, a connecting rod assembly, and a drive shaft. The power section may include a stator and a rotor with the rotor configured to rotate eccentrically when a drilling fluid is passed through the stator. The connecting rod assembly operatively connects the rotor of the power section and the drive shaft of the bearing section. The connecting rod assembly may include a housing and a connecting rod. The housing may have a proximal end and a distal end with the proximal end connected to the stator. The connecting rod may include a proximal end including a rigid connection operatively connected to the rotor, a mid flexible rod, and a distal end terminating at or proximate an articulating joint. The drive shaft may be operatively connected to the articulating joint.
