摘要:
A shilly-car includes a main frame module with a rear-wheel tube and a main-frame tube, a front connecting tube and a swing module. A seat cushion is mounted onto a T-shaped structure comprised of the rear-wheel tube and main-frame tube, and two wheels are installed at both ends of the rear-wheel tube respectively. The swing module includes a pedal tube and a swing tube having a bearing sleeve and a bearing. The front connecting tube has an end rotably fixed to the swing tube and the other end fixed with the main-frame tube, and a C-shaped fixed element is installed at an end of the front connecting tube for receiving the bearing sleeve and the bearings, and a fixing shaft is provided for rotably fixing both bearing sleeve and bearing, so that the pedal tube can be stepped by both legs of a rider to move the shilly-car forward.

Elastomeric multicomponent fibers and bonded fiber structures formed from elastomeric multicomponent fibers are disclosed. The elastomeric multicomponent fibers may comprise a thermoplastic polymer core material and an elastomeric polymer sheath material surrounding the core material. The bonded fiber structure may comprise a plurality of fibers bonded to each other at spaced apart points of contact, at least a portion of the fibers being multicomponent fibers having at least one elastomeric fiber component.

The invention is generally directed to a vapor emitting device having a container, at least one liquid in the container, and a wick. The container has an interior in which the at least one liquid is disposed. The wick has a distal portion disposed in the container interior and a proximal portion. The wick is configured and positioned so as to maintain contact with the at least one liquid and allows the wick to draw the at least one liquid into and through the distal portion toward the proximal portion, thereby making the at least one liquid available for evaporation when the proximal portion is exposed to air. A change in a visible characteristic of the wick occurs upon exhaustion of the at least one liquid from the wick.

A barrier element for use in separating blood components is provided. The barrier element comprises a self-sustaining, fluid transmissive body comprising a plurality of thermoplastic fibers bonded to each other at spaced apart points of contact, the fibers collectively defining a tortuous fluid flow path through the fluid transmissive body from a fluid inlet surface to a fluid outlet surface, the fibers and the fluid transmissive body being configured to allow passage of at least one blood component therethrough while preventing the passage of a second blood component.
摘要:
A bonded fiber ink reservoir, an ink jet printer cartridge containing a bonded fiber reservoir, and a ink jet printer using an ink jet cartridge containing a bonded fiber reservoir are disclosed. The bonded fiber reservoir may comprise a three dimensional bonded fiber structure, wherein the three dimensional bonded fiber structure is comprised of a plurality of fibers bonded to each other at spaced apart points of contact, at least a portion of the fibers being multicomponent fibers having at least one elastomeric fiber component.

An adjustable seat includes a seat frame and an adjustable assembly. The seat frame includes a first seat body and a second seat body spaced apart each other to define an adjustment channel between the first and second seat bodies. The adjustable assembly is supported underneath the seat frame for selectively adjusting a distance between the first and second seat bodies, wherein the adjustable assembly includes two adjustable members coupled at the first and second seat bodies respectively, and an adjustor rotatably coupled between the adjustable shafts. The adjustor is driven to rotate at a rotatable direction along a centerline of the adjustment channel to selectively adjust a width of the adjustment channel so as to selectively adjust the distance between the first and second seat bodies.

A hand-swing type shilly-car includes a main frame module and a hand-swing module. The main frame module includes a rear-wheel tube, a T-shaped structure formed by the rear-wheel tube and main-frame tube and having a cushion, two wheels installed at both ends of the rear-wheel tube respectively, and a pedal tube installed at the front of the main-frame tube. The hand-swing module includes a swing tube, a handlebar at the top of the swing tube, a guide wheel at the bottom of the swing tube, a bearing sleeve at the top of the swing tube and opposite to the guide wheel and having a bearing at the top and bottom of the bearing sleeve. A fixing element with a C-shaped structure is installed at the main-frame tube for receiving both bearing sleeve and bearings, and a fixing shaft is provided for rotably fixing the bearing sleeve and bearings.
