Title: Fabric surface structuring - uses separate fine needles to beat against material on rough surface
Inventor: HEINITZ VOLKER
IPC: D06B11/00
Filed: 1990-05-03
Abstract: To give a surface finish over the whole surface and/or patterned zones of piecegoods, to give a mechanical and/or mechanical-thermal action with a matted and/or gloss character, separately controlled fine needles (8) beat temporarily against the material. The needles (8) are of different types and/or of different materials at their heads, to give point modification to the fabric surface at different points and to different degs. The fabric (1) has its surface to be treated at a small gap. from or in loose contact with a rough surface, so that the beating action of the needles presses the material against the rough surface. A stamp is operated by a cam to give a series of blows in repeating lines over the fabric (1) width which rides on a heated or unheated beam or the like as a beating surface which is smooth or rough as required. With an arrangement of separate stamps, they are operated under pattern control. The needle heads are round, flat, serrated and of tempered or untempered materials, separately or in combinations. A layer of non-thermal conductive material acts as an intermediate layer between the needles (8) and their heads, so that they can be heated or cooled by an electrical eddy current or a Peltier effect, or a gas stream. A computer (27) controls the separate needle head temps. and the disposition of the needles (8). As the needle system strikes the fabric (1), there is a relative movement speed between the rough supporting surface and the material (1), with the support moving faster than the fabric. -

Title: Recycling roll scale - grinds collected scale to be used with coal as fuel dust blown into blast furnace
Inventor: FECHNER BRUNO
IPC: B09B3/00
Filed: 1991-02-11
Abstract: To recycle roll scale, especially from rolling steel and especially profile steel, the scale is collected and ground to be used as an additive with mineral coal to be blown into a blast furnace. The scale is ground and dried to be blown into the blast furnace as fuel dust. While the scale is being ground, it is pref. contained within an inert atmos. and heat is applied. The roll scale and the mineral coal are ground to less than 0.2 mm and sieved at 0.2 mm. The ground scale is used at a rate of 5-20% of the mineral coal, and pref. 6-8%. The roll scale is partially dried before grinding. The ground scale and mineral coal are blown into the blast furnace while they are still hot. The scale and the coal are ground together, at the same time, in the same grinder. In another form, a small amount of mineral coal is dried and ground and the scale/coal mixt. is mixed on blowing in as a fuel dust, or ground scale is mixed separately with oil for injection into the blast furnace. ADVANTAGE - The process not only gives a use for roll slag containing oil, but eliminates the need for special disposal arrangements through the composition of the scale.
