Abstract: With the process for the production of iron from an iron-oxygen combination, preferably ore, the iron-oxygen combination is essentially reduced in an ore reduction vessel with a reaction gas from a melting crucible, then supplied to this melting crucible and melted by adding carbon-containing fuels and oxygen-containing gases. According to the invention, the reaction gases escaping from the melted iron are partially subjected to after-burning in the melting crucible. The thus developing heat is largely transmitted to the melted material and the reaction gases are cooled and reduced with reducing agents on their way to the ore reduction vessel.

Abstract: A textile yarn creel having a circular supporting framework and plural yarn package supporting members mounted removably and circumferentially slidably thereabout and axially thereof, the supporting members having plural radially inwardly extending pins for mounting of yarn packages thereon for radially inward yarn withdrawal. Guide eyelet members are mounted in a circular arrangement on the circular framework radially inwardly spaced from the package supporting members for receiving the yarns and for direction therefrom to an associated textile machine e.g. a multi-feed circular knitting machine. The package supporting members may be selectively mounted at substantially any locations and spacings circumferentially about the framework for selective expansion and reduction of the creel capacity without changing the floor space occupied. In one embodiment, pivoted arms carry the package supporting pins while in another embodiment the package supporting members are selectively movable radially of the circular framework as well as circumferentially thereabout. The circular nature of the creel and the adjustability thereof give it substantially greater capacity per unit floor space occupied than any known conventional creel. A rotating compressed air blowing arrangement is intermittently operable for removing and preventing lint accumulation on the creel.

Abstract: A transdermal delivery system (1,11) for the transdermal administration of a drug has   (a) a backing (2,12) that is substantially impermeable to the drug,   (b) a matrix (3,13), adjacent to a surface of the backing, the matrix containing a gel comprising a hydrophilic fluid, a fluid gelling agent and the drug, and (c) a perforated sheet (4,14), adjacent to the matrix, that allows passage of the drug containing gel through its perforations. Preferably the system also has a contact adhesive layer (5,15) and a protecting layer (6,16).   The long term adhesion of the delivery system to a patient may be effected by forming a channel (17), surrounding the matrix, in the perforated sheet/contact adhesive layer lamina. The channel inhibits the lateral movement of the drug containing gel. Furthermore, by forming a weak seal (18) in the matrix surrounding channel, the loss of a volatile drug from the gel may also be prevented.
