Abstract: A delivery system for feeding particulate matter to a target location at a well site, including a transportable conveyor belt assembly; one or more silos in fluid communication with a particulate supply line, each of the silo inlets extending through a side wall of the respective silo and disposed at a different location from the others along a longitudinal axis of the respective silo; and for each silo an enclosed chute detachably attachable thereto so as to receive into the chute particulate matter gravity fed out of the respective silo and convey such matter into the housing of the conveyor belt assembly. The silos, the chutes and the housing enclose the particulate matter as it passes from the silos through the chutes and conveyor belt assembly to the target location, to inhibit the release of dust generated from movement of the particulate matter from the silos to the target location.

Abstract: A container lid is disclosed that accepts a snap-on container. The lid includes a continuous outer coupling trough for attachment to the open top of a beverage container where the trough circumscribes a footprint of the container lid. A straw-hole planar surface is disposed within the footprint, the straw-hole planar surface is adjacent to the outer coupling trough and a hole for drinking a liquid in the container extends through the straw-hole planar surface. A riser wall extends away from the straw-hole planar surface and defines a first planar surface above the straw-hole planar surface. A sip hole extends through the first planar surface. A food container coupling wall connects to the first planar surface and extends from the first planar surface to a position lower than the first planar surface and a food container coupling bottom connected to the food container coupling wall.

Abstract: A retention system is provided for use in connecting a replaceable tool to a work implement. The retention system may have a generally cylindrical pin with a first hollow end, and a second hollow end located opposite the first hollow end. The retention system may also have a first fastener configured to engage the first hollow end and cause the first hollow end to flare radially outward. The retention system may further have a second fastener configured to engage the second hollow end and cause the second hollow end to flare radially outward.

Abstract: A food container coupling system includes a food container configured to attach to a bottle coupler. The food container includes a food compartment with a side wall and a bottom, which has a food compartment coupling structure extending therefrom. The system also includes a bottle coupler with a top rim and a bottle coupler coupling structure extending from the top rim. The bottle coupler further has an annular opening adapted to fit around the neck of a bottle, a small can or a large can. When the food container is mounted to the bottle coupler, the food compartment coupling structure mates with the bottle coupler coupling structure.

Abstract: A pin for use in a dynamic pin joint is provided that comprises a core member that defines a longitudinal axis and an outer diameter and a self-lubricating material overlay that is disposed about the outer diameter of the core member along at least a portion of the longitudinal axis of the core member.

Abstract: A food container coupling system is disclosed that includes a food container configured to attach to a can or a beverage container lid/coupler. The food container includes a food compartment with a side wall and a bottom, which has a food compartment coupling structure. The food compartment coupling structure has an inner wall coupling structure with an inner wall jut, and is shaped complementary to the rim of a beverage can and when the food container is mounted to the beverage can, the food compartment coupling structure mates with the beverage can rim. The system may also include a beverage container lid/coupler with a coupling ring adapted to mate with the rim of a beverage container, wherein the rim defines a second plane, and a beverage container lid coupling structure extends from the second plane and can mate with the food compartment coupling structure.

Abstract: A food container is disclosed that is configured to attach to either (1) a beverage container lid, the lid comprising a lid wall with a lid coupling structure, or (2) a rim of a beverage can. The food container includes a food compartment comprising a side wall and a bottom and a food compartment coupling structure extending from the bottom outer wall coupling structure and an inner wall that further comprises an inner wall coupling structure. When the food container is mounted to the beverage container lid, the outer wall coupling structure mates with the lid coupling structure. When the food container is mounted to the beverage can, the inner wall coupling structure hooks underneath the rim.

Abstract: A fluid powered circuit for a gearbox and a method for protecting a gearbox are disclosed. The fluid powered circuit includes a control circuit operatively connected to a clutch engagement circuit. The fluid powered circuit is selectively operable to either flow a fluid from a fluid supply source to the clutch or vent the fluid to the atmosphere. The method for protecting the gearbox includes flowing the fluid from the fluid supply source to the fluid powered circuit, measuring the speed of the shaft, measuring the pressure of the fluid entering the clutch engagement circuit, and flowing the fluid from the fluid powered circuit to the clutch upon detecting one or more conditions.
