摘要:
Denim fabric, suitable for use as apparel, and garments made therefrom, wherein the denim fabric is made from at least about 50 wt % fibers produced from post-consumer recycled polyester and recycled cotton. In particular, warp yarns are made of recycled cotton and the other cotton, and the filling yarns are made of the post-consumer recycled polyester and spandex material. The warp yarn may be plied with like reclaimed warp yarn, and/or with virgin fiber warp yarn. The warp and filling yarns are combined to make the denim fabric. The denim fabric produced has strength and related properties sufficient for consumer use. The fabric or garment may also be subjected to washing, handwork, and/or other finishing effects that would change the look and feel of the fabric or add special characteristics.

A liquid delivery apparatus includes a base assembly; a vessel into which liquid may be introduced to at least partially fill the vessel and to pressurize the liquid in the vessel; a nozzle including a discharge tube and a nozzle outlet, wherein the nozzle is rotatable with respect to the base assembly, and the nozzle outlet is provided at a distal end of the nozzle via which the liquid may be discharged from the vessel under the pressure of the liquid in the vessel; and a valve between the vessel and the nozzle to control passage of liquid from the vessel to the nozzle outlet; wherein the valve and nozzle discharge tube are substantially in line. A drive system is also disclosed that drives rotation of the nozzle with respect to the base assembly. The drive system may be configured to propel the liquid delivery apparatus along the ground.

A belt positioner 1 for installing a flexible belt into a grooved periphery 12 of a pulley 11. The positioner 1 comprises a belt guiding ramp 2, a pulley flange engaging mechanism 3, a handle 4 and a belt guiding rim 5. The belt guiding ramp 2 is extendible across the grooved periphery 12 and a belt-bearing slanting surface 20 of the ramp 2 enables the belt to be moved into engagement with the grooved periphery 12 when the pulley 11 is rotated about its rotational axis. The pulley flange engaging mechanism 3 comprises a groove 30 extending across the positioner 1 for receiving a pulley flange 13 bordering the grooved periphery 12 and a shoulder 31 bordering the groove 30 for bearing against a side face 14 of the pulley flange 13, wherein the engaging mechanism 3 locks the positioner 1 to the pulley 11 while the belt bears against the slanting surface 20. The handle 4 extends from the ramp 2 and provides a gripping surface 42 for fingers adjacent the ramp 2. In use the handle 4 extends laterally of the grooved periphery 12 and substantially parallel with the rotational axis of the pulley 11. When installing a belt, the positioner 1 need not engage a shaft of the pulley 11 nor be mounted to the pulley 11 in any additional way.

摘要:
A liquid delivery apparatus includes a vessel having an inlet and an outlet, and a valve between the vessel and the outlet. The valve has an opening, a closure member for closing the opening, and a biasing means to hold the valve in a normally-closed position. A valve control mechanism controls operation of the valve in response to pressure of liquid and air in the vessel. A transmitting means transmits the pressure to the valve control mechanism. The valve control mechanism includes a moveable element that can be acted on by the pressure in the vessel and transmit a resultant force to the closure member to thereby open the valve. The respective effective surface areas of the moveable element and the closure member and the force of the biasing means are chosen such that the closure member is openable when the pressure in the vessel reaches a predetermined level.

This invention is directed to mutant SPE-C toxins or fragments thereof, vaccine and pharmaceutical compositions, and methods of using the vaccine and pharmaceutical compositions. The preferred SPE-C toxin has at least one amino acid change and is substantially non-lethal compared with the wild type SPE-C toxin. The mutant SPE-C toxins can form vaccine compositions useful to protect animals against the biological activities of wild type SPE-C toxin.
