Abstract: A fastening device including a first tube defining a first major axis, a distal portion, a proximal portion, and a through hole, the proximal portion of the first tube including an attachment element. A second tube is disposed within the through hole of the first tube, the second tube defining a second major axis that is substantially orthogonal to the first major axis. The attachment means may be one or more notches, a flange, a socket, a wedge and a clamp, or an arm. The first tube may have a bend, and the bend may be between approximately 25° and approximately 30°. Further, the second tube may define a second tube length, and may include a first component and a second component that screw together to provide an adjustable second tube length. The first tube and second tube may be pivotally coupled.

Abstract: A fastening device includes a tube defining a first axis, a tube first end, a tube second end, and a through hole, the through hole defining a first opening and a second opening, a second axis of the through hole being substantially perpendicular to the first axis of the tube, the tube second end of the tube securing rigidly to an attaching device. The fastening device also includes a cord inserted through the through hole, the cord defining a cord first end and a cord second end, the cord first end disposed on a side of the through hole corresponding to the first opening, the cord second end disposed on a side of the through hole corresponding to the second opening. The cord first end is looped over the tube first end of the tube.

Abstract: A fluid dispensing apparatus having a) a compressed gas or CO2 cartridge controller, b) a hydraulic pressure medium connected to the CO2 cartridge controller, c) a flow control valve connected to the hydraulic pressure medium; and d) a hydraulic piston connected to the hydraulic pressure medium, whereby a CO2 cartridge applies pressure to the hydraulic pressure medium controlled by the CO2 cartridge controller, the flow control valve is operated to precisely meter hydraulic fluid to the hydraulic piston, and the hydraulic piston provides the linear force to dispense a fluid product with similar and matching regulation under pressure. A rotary valve can be provided to use spent CO2 to retract the piston.
