Abstract: A bed frame that can be assembled without the use of tools. The bed frame can also be easily collapsed into a relatively compact package since the normal long side rails are comprised of two components that can be manipulated such that the two components can be in an end to end orientation when the side rails used in a bed frame or in a generally side by side orientation to facilitate shipping and storage. The cross rails can also be formed of two components that can be moved between an end to end orientation and a generally parallel orientation. A locking system locks certain of the components into a fixed position when in the end to end orientation.

Abstract: A dismantlable electric bed includes a fixation frame, a moveable frame, and an actuator. The moveable frame includes two longitudinal rods and a transverse rod having two ends. The two longitudinal rods are pivotally connected with the fixation frame, respectively. Each longitudinal rod has at least one insertion hole. Each end of the transverse rod is provided with at least one post detachably inserted into the at least one insertion hole of one longitudinal rod. The actuator has two ends pivotally connected with the fixation frame and the transverse rod, respectively. As such, the electric bed is dismantlable to reduce the packing volume thereof and convenient to be assembled by the user herself/himself.

Abstract: The present invention relates to an extendable folding saw that is lightweight and compact when retracted yet rigid when extended. In one embodiment, the extendable folding saw can have a folding saw and a removably attached extension. The folding saw can have a grip and a pivotally attached saw. The extension can comprise several members that are compactable to a length not much greater than the length of the longest individual member. The members of the extension can have a generally I shaped profile. The extension rod can be attached to the folding saw in a snap-fitting manner for use. A retracted folding saw can be snapped side-by-side to a retracted to extension rod for storage.

Abstract: The invention relates to a method for the production of synthetic filament yarn having crepe characteristics by simultaneous drawing and falsetwisting of the filament yarn while imparting a twist by means of a falsetwister, as well as--under certain conditions--drawing of the filament yarns to a ratio of at least 1:1.08.
