Abstract: Stone slabs, and systems and methods of forming slabs, are described. Some example slabs include a pattern defined by a particulate mineral mix. The pattern includes one or more characteristics that differ from other regions of the slab where the pattern is not present.

Abstract: Stone slabs, and systems and methods of forming slabs, are described. Some example slabs include a first pattern defined by a first particulate mineral mix and a second pattern defined by a second particulate mineral mix different from the first particulate mineral mix. The first particulate mix includes greater than 50 weight percent of first metallic particles.

Abstract: A roller rail system includes an adjustment bracket including a first roller rail assembly support portion and a second roller rail assembly support portion adjacent the first roller rail assembly support portion. The first and second roller rail assembly support portions are each configured to receive a roller rail assembly such that the roller rail assembly slides within the respective first and second roller rail assembly support portion relative to the adjustment bracket. A first roller rail assembly is received by the first roller rail assembly support portion. A second roller rail assembly is received by the second roller rail assembly support portion. The roller rail system has a retracted configuration where leading ends of the first and second roller rail assemblies are closer together and an extended configuration where the leading ends of the first and second roller rail assemblies are further apart.

Abstract: An automated system for disassembling a roller rail assembly includes an actuation device configured to move the roller rail assembly in a disassembling direction. A guide bracket is arranged and configured to receive the roller rail assembly as the roller rail assembly is moved in the disassembling direction. The guide bracket allows movement of the roller rail assembly in the disassembling direction. A separator member is located downstream of the actuation device. The separator member being received by a housing member of the roller rail assembly and having a wide region that separates sidewalls of the housing member and releases roller wheels of the roller rail assembly as the roller rail assembly is moved past the separator member by the actuation device.

Abstract: A method of releasably connecting a child hand truck to a parent hand truck is provided. The method includes lifting a handle assembly to a raised position. The handle assembly is locked in the raised position using a lock and release mechanism.

Abstract: A toy gun is disclosed that may have a pressurized elastomeric supply bladder in fluid communication with an elastomeric pulse bladder via a trigger valve. The pulse bladder may also be in fluid communication with a pulse nozzle via a pulse valve that is operatively connected to the pulse bladder so that the pulse valve moves from a closed position to an open position when the pulse bladder expands. When the supply bladder is filled with pressurized liquid and the trigger valve is opened, pressurized liquid from the supply bladder is forced into the pulse bladder. As the pulse bladder expands, the expansion eventually causes the pulse valve to open and cause a burst of liquid to be discharged from the pulse bladder through the pulse nozzle.

Abstract: The invention is directed to a toy projectile launcher for discharging a toy projectile attached thereto that may include a housing, a hollow outer cylinder, and a compression member that may be disposed on the housing, and slidably received within the hollow outer cylinder. The compression member may include a fluid passage therethrough in fluid communication with the interior of the outer cylinder. The interior of the outer cylinder may be moveable between an uncocked position and a cocked position such that movement of the outer cylinder from the cocked position toward the uncocked position compresses air in the interior of the outer cylinder, with the compressed air being delivered to through the fluid passage to a toy projectile attached to the toy projectile launcher. The toy projectile launcher may also include a spring that may bias the outer cylinder from the cocked position toward the uncocked position.

Abstract: A system for securing a drill bit against rotation in a drilling rig of the type having a rotary table with an opening which is smaller than the drill bit. A breaker plate is supported in a frame below the rotary table. The breaker plate includes an irregularly shaped opening for engaging the drill bit when the drill string is raised. A sub is connected between the bit and the drill string. The sub can be rotated by the rotary table when the bit is held by the breaker plate to attach or detach the bit.
