Abstract: The gas compression method/system restricts flow of emulsified liquid-gas mixture through many substantially radial capillary tube-passages in a rotating disk by either one-way valves, narrowing the passages, hydraulic impedance and/or reinforcement of coriolis forces in terminal end tail segments of the capillary passages. Compressed gas is released from peripherally collected compressed gas-liquid emulsion (beyond the terminal ends of the tubes) in a arcuate peripheral disc space when the compressed gas bubbles emerge from the peripherally collected emulsion. A compressed gas drain draws off gas from the peripheral space. Liquid drain draws off liquid from the space. In different embodiments, radial outboard flow through the capillaries is effected by various one-way valves which may be a single valve in the passage or multiple valves. Coriolis force in tail segments is enhanced by angular displacement in the direction of rotation. Valves may be used in combination with such tail-end segments.

Abstract: The present screw anchor advantageously has two fins radially extending from the body of the screw anchor, where the fins additionally extend above the top end of the body. This unique fin design permits the user to drive the screw anchor into the worn screw hole within a wood substrate so that the screw anchor is substantially flush or recessed within the worn screw hole. When the fins are aligned with the grain of the wood, the fins split the wood at the grain and prevent rotation of the screw anchor. Because the screw anchor is flush or recessed, the anchor does not interfere with the installation of hardware overtop the anchor, such as a hinge. Furthermore, the original screw, such as in the case of a door hinge, can be reused to create an invisible repair.
