Abstract: A system, a machine-readable storage medium storing instructions, and a computer-implemented method are described herein for a challenge engine. The challenge engine identifies a set of player metrics for players within a game and determines properties of at least one metric of the set of player metrics for a specified player. The challenge engine generates a first gaming instance based on the properties of the at least one metric. The first gaming instance is customized to the specified player. The challenge engine detects one or more interactions of the specified player with at least one element of the first gaming instance. In response to the one or more interactions, the challenge engine generates a second gaming instance based on the properties of the at least one metric. The second gaming instance is customized to the specified player and distinct from the first gaming instance.

Abstract: A roll grooving apparatus has a back-up roller, a grooving roller positioned vertically below the back-up roller, and a linear actuator positioned below the grooving roller. The linear actuator drives the grooving roller linearly toward the backup roller. A drive is coupled to turn the backup roller. A tubular workpiece is mounted with its wall between the two rollers and compressive forces are exerted on the wall as the backup roller rotates, thereby extruding a circular groove in the workpiece.

Abstract: A diffuser (10) having a body (12) with a blind bore (18) having a closed impaction end (22). Fluids are diffused radially from the body (12) through slots (26). The diffuser (10) is characterized by a central slot (28), a lower slot (3) and an upper slot (32). The central slot (28) discharges a first fluid stream (34) substantially horizontally. The lower slot (30) discharges a second fluid stream (36) at an upward angle to impinge upon the first fluid stream (34). The upper slot (32) discharges a third fluid stream (38) at a downward angle to impinge upon the first fluid stream (34). The diffuser, as described above, has proven to be effective for use in aeration of water for aquaculture.

Abstract: A hitch receiver has a clamp-on funnel shaped open mouth for receiving and guiding a hitch shank entry. Attached in the funnel mouth of the hitch receiver, a shank neutral position indicator includes a generally horizontal spring mounted with one end of the spring held at one side of the open mouth and an opposing end of the spring loosely held and movable within a vertical elongate slot on the other side of the open mouth. The spring is positioned such that with a hitch shank centered within the hitch receiver, the hitch shank moves the spring to a center position of the elongate slot thereby indicating that receiver and shank are mutually free for disengagement. A hitch shank engagement limiter within the hitch receiver, has an adjustable length which is selected for stopping hitch shank entry travel into the hitch receiver when receiver and shank hitch pin holes are aligned.
