Abstract: An exemplary derrick assembly includes a frame, a hydraulic cylinder assembly, a drive assembly, and a hydraulic assembly. The hydraulic cylinder assembly is mounted to the frame, and includes a piston rod, a single-tube cylinder body, and a hydraulic chamber. The piston rod is secured to the frame, and the cylinder body is mounted to the piston rod for reciprocal movement between proximal and distal positions. The hydraulic chamber is defined in part by the piston rod and the cylinder body, and expands and contracts with movement of the cylinder body. The drive assembly is mounted to the cylinder body for movement with the cylinder body. The hydraulic assembly configured to charge hydraulic fluid into and out of the hydraulic chamber to cause the hydraulic chamber to expand and contract, thereby moving the cylinder body and the drive assembly between the proximal position and the distal position.

Abstract: A supplement dispensing mouthguard device is an apparatus that readily supplies supplements into the mouth of a user while the user is performing an exercise. The apparatus includes an upper U-shaped platform, a lower U-shaped platform, an inner curved wall, an outer curved wall, a main fastener, a supplement reservoir, at least one inlet, and a plurality of outlets. The upper U-shaped platform and the lower U-shaped platform protects the teeth. The inner curved wall and the outer curved wall protects the tongue and the inner walls of the cheeks of the user. The main fastener connects the upper U-shaped platform with the lower U-shaped platform and seals the at least one inlet. The supplement reservoir contains the desired supplement. The at least one inlet provides access into the supplement reservoir. The plurality of outlets distributes the supplement into the mouth of the user.

Abstract: A bottle shredder is disclosed. The bottle shredder features a bottle holder, sized to receive a plastic bottle, a wire cutter and bottle support, both of which are located below the bottle holder. The bottle holder is attached to a linear slide, which is capable of moving the bottle holder directly above a shredding apparatus. The shredding apparatus contains at least one feed roller operatively connected to a first motor, a spur gear, a bearing block, featuring at least one bearing, and at least one shredding blade operatively connected to a second motor via the spur gear and bearing block. Below the shredding apparatus is a finished shreds chute, which collects the post-shredded bottle parts.

Abstract: A system includes a rack with rows for storing drill pipe, and a moveable structure having a control support coupled to an upper portion and a lifting device coupled to a lower portion. The moveable structure travels along a guide for positioning adjacent any of the rows. The control support includes a pivoting actuator, a rotating actuator, an extension arm having a drill pipe capture actuator, and an extension actuator. The lifting device includes a lifting actuator that raises a stack of drill pipe. The system further includes a controller that interprets a control support state including actuator positions and a position index value, and records a position description including the control support state corresponding to the position index value. The controller interprets a position request signal and provides actuator control signals in response to the position request signal and the position description.
