Abstract: Described are metal products having spatially non-uniform strength and formability profiles. The spatial non-uniformity of these properties may be achieved by heat-treating the metal product in a spatially non-uniform fashion, such that different portions of the metal product exhibit different strength and formability characteristics. The metal products may be formed into stamped products, with strength and formability characteristics customized to allow for suitable drawing during the stamping process.

Abstract: A moisture wicking fabric has one side comprised substantially entirely of inherently hydrophobic fibers such as polyester or polypropylene and the other side comprised of a mixture of hydrophobic fibers such as polyester or polypropylene and hydrophilic fibers, particularly cellulosic fibers such as cotton, lyocell and viscose rayon. A garment can be formed from such a moisture wicking fabric, for example by the whole garment knitting method, the side comprised of the mixture of fibers being the external side of the garment.

Abstract: A projection screen is formed of at least one screen layer comprising a non-interference pigment. Methods for forming a projection screen comprise the steps of: applying a primer composition onto the substrate to form a primer layer and applying a screen composition onto the primer layer to form a screen layer. Projection screen kits comprise an individually packaged base composition and an individually packaged reflective additive composition.

Abstract: A sewing thread consists of from 70 to 95 percent by weight of lyocell fibre and from 5 to 30 percent by weight of at least one synthetic fibre such as polyester or polyamide. The sewing thread can be used for sewing garments, particularly those comprising a major proportion of cellulosic fibres, and can be dyed with a dyestuff for cellulose.

Abstract: A wound dressing has its wound-contacting surface composed of a tow or strand of textile filaments at least 15 mm long or a fabric of textile filaments at least 3 mm long, substantially all of the filaments being non-crosslinked carboxymethylcellulose filaments capable of absorbing at least 15 times their own weight of 0.9% aqueous saline solution. The wound-contacting surface forms a swollen, transparent gel which retains sufficient fibrous character to be removable as a coherent dressing from the wound.

Abstract: A wound dressing comprises a chemically modified polymer which has a free radical activity in the DPPH Test in the range 15-80 percent. It may comprise a chemically modified polymer which carries at least one chemical group which is a persistent free radical or a precursor therefor. It may comprise a chemically modified polymer which carries at least one chemical group capable of reacting with molecular oxygen in a wound environment to form hydrogen peroxide. It may comprise a chemically modified polymer capable of stimulating the activity of macrophages or the proliferation of fibroblasts or both in a wound environment.

Abstract: In a tube boiler, fuel is burned in a fluidized bed which has a shallower part and a deeper part. The tubes extend only through the shallower part which can be fluidized independently of the deeper part so that the rate of heat transfer from the bed to the tubes can be varied according to demand. Water flows through specially configurated, upwardly oriented tubes by natural convection. There is also a general circulation of particles within the bed.
