Abstract: A rapid palatal expander for stretching a patient's upper jaw bone sideward horizontally and forward to accommodate front teeth. It has a dual-joint jack screw with two rocker arms having respectively one end pivotally engaged with two spaced fulcrums and another end engageable with a screw bar. Turning the screw bar will move the rocker arm moving outward to push upper barrel bands mounted on the molar and premolar horizontal outward to expand the upper jaw bone. There is an elastic means with two ends engaged with the upper and lower barrel bands mounted respectively on the upper and lower molar and premolar. When patient's mouth is closed, the elastic means will be compressed to produce a horizontal force to push the upper barrel band forward. Thus the upper jaw bone and the teeth may also receive a constant forward pushing force for expanding purpose.

Abstract: A reverse osmosis water treatment system includes a tube connecting unit 10 having a water incoming end 102, a water outgoing end 103, and a diaphragm 104 having a check valve 108 therein to allow water to flow directly from the incoming end to the outgoing end. In operation, water flows from the tube connecting unit through-hole 105 and into preliminary filtering units 2 and membrane unit 3 via the pipe assembly 1. Wastewater from the membrane unit drain end 31 is then routed back to the tube connecting unit via pipe assembly 42 and through-hole 106.
