Abstract: An artificial decorative plant of the present invention is to assemble multiple branches first and then assemble with a main stem. Each branch is composed of a rod with resilience, a securing piece and multiple branch strips, wherein the securing piece has two longitudinal sides and multiple clamping pieces alternatively staggered extended from the two longitudinal sides respectively with multiple intervals and applied to wrap the rod. Additionally, multiple clamping attachments are extended from the two longitudinal sides inside the multiple intervals respectively so that the each clamping attachment is between two adjacent clamping pieces to engage a corresponding branch strip with leaves. After completing assembly of the securing piece and the rod, the combination engages the main stem by a hook element on the rod. Because of such structure, it not only enhances the combinational strength and further improves efficiency of assembly convenience.

Abstract: A takedown artificial tree includes a plurality of flexible branches, each of the branches including a substantially straight, hollow main stem and a plurality of fronds extending from the main stem; a plurality of fixing brackets made of rigid material, each of the fixing brackets including a hollow cylinder and a hollow branching member obliquely upward extending from the cylinder; and a trunk made of metal, the trunk being frictionally inserted through the fixing brackets to serve as a support of the finished artificial tree. Base of the main stem of each branch can be inserted into the branching member for fastening. No assembly by a buyer is required. There is no worry of the branches falling onto the ground.

Abstract: The present invention relates to a novel method of determining the pressure-volume (P/V) curve of the respiratory system as well as a ventilator containing a pertinent tool for recording the pressure/volume curve.

Abstract: A new eyeglass frame, eyeglass frame component and method for making eyeglass frames or parts thereof of a nickel-free titanium based SMA. A pseudoelastic &bgr; titanium alloy is used which has superior fabricating characteristics combined with weldability with pseudoelastic properties over the temperature range of −25° C. to 50° C. making this alloy ideally suited for the manufacture of various eyeglass components. The disclosed eyeglass component alloy is a &bgr; titanium alloy contains alloying elements of molybdenum between 10.0 and 12.0 weight percent, aluminum between 2.8 and 4.0 weight percent, chromium and vanadium between 0.0 and 2.0 weight percent, and niobium between 0.0 and 4.0 weight percent. The eyeglass components fabricated from this alloy exhibit a strain recovery of up to 3.5% deformation, a lower stiffness than conventional binary nickel titanium alloys yielding superior wearer comfort.
