Abstract: A multifunctional fiber with full-spectrum infrared radiation, flame retardant and antibacterial functions, including a composite masterbatch having a water content of 30-50 ppm and accounting for 10-12% by weight, polyethylene terephthalate having a water content of 25-30 ppm or polycaprolactam high polymer having a water content of 50-70 ppm and accounting for 88-90% by weight; the fiber and its fabric possess multiple functions such as spectral heating, flame retardancy, anti-bacteria and anti-virus; after being illuminated for 5-10 minutes, the temperature difference of the fiber fabric of the present invention is higher than 15-20° C., the far-infrared emissivity is greater than 98%, the radiation temperature rise is greater than 3.0° C., the CLO value is greater than 0.5, the heat transfer coefficient is greater than 18.0w/(m2k), and the thermal resistance is less than 0.05 (m2k)/w.

Abstract: A hydraulic jack comprising a hydraulically actuated saddle movable from a first lowered position to a second raised position, the jack having a handle which, when pumped up and down, hydraulically raises the saddle, lowering control means associated with the jack for preventing premature lowering of the saddle upon malfunction of the hydraulic actuation during raising of the saddle and a release lever engaging the lowering control means adapted to release the same and permit lowering of the saddle when the handle is pumped up and down.

Abstract: A jack stand and method for forming the same wherein the jack stand includes a base having at least 3 elongated support legs formed from a cylindrical metallic tube. The legs are braced and have support feet at bottom and terminate at top in a hollow cylindrical collar having a throughbore. A solid post, with a saddle at top, reciprocates within the collar. The post has a plurality of horizontally extending throughbores and a locking pin is extended through the throughbore in the collar and into one of the horizontally extending throughbores in the post locking the post in various positions.

Abstract: A convertible stool is interchangeable between a utility function which has a seat movable up and down and has casters as feet at the end of legs connected with the seat through an upstanding member. In a second use, the casters are replaced by feet to give stability to the chair on a floor or base. As such, the second use can be a furniture type use.

Abstract: A cargo carrier has a platform section. A set of foldable wall elements is for location in a first position substantially flat with a support region and in a second position substantially upright relative to the inner cargo support region. There can be two platform sections bolted together to form the overall platform section.

Abstract: A ramp for a vehicle comprises an elongated track with a leading end and a trailing end. The leading end engages a flatbed platform of a vehicle, and the trailing end engages a ground surface so that there is a slope between the leading and trailing ends when the ramp is in a first usage. The elongated track is constituted by multiple engaging elements. The elements are movable relative to each other so that the elements are capable of being packed in a stack to define a platform for a wheel of a vehicle. This permits raising of the wheel of a vehicle above the ground level. There is a hinge between adjacent elements, and the elements of the ramp are hinged at opposite ends for relative folding to permit for a stacked relationship about adjacent ends.

Abstract: An apparatus and method that attaches to a tire and supplies a step to enable access to the engine compartment or rooftop of a vehicle is provided. The apparatus is adjustable to better fit with a variety of different sized tires. The apparatus is also adjustable to allow the apparatus to rest at different height locations on the tire. Additionally, the tire step can be folded for easier storage.
