Title: Soft free-cutting steel contg. large sulphide inclusions - where controlled deoxidation of molten steel in ladle ensures good surface finish during machining
Inventor: SCHOOP JOSEF DR ING
IPC: C21C7/06
Filed: 1978-05-29
Abstract: The inclusions have the shape of a lens, but the semi-finished prods. machined from the steel have a good surface finish obtd. by measuring the oxygen content of the molten steel in the ladle and then injecting a deoxidant to reduce the oxygen to teh deisred percentage. The oxygen content of the molten steel is pref. measured via electromotive force; and the dissolved oxygen in the melt is pref. reduced to 30-130 ppm, esp. 40-60 ppm, prior to casting. The pref. deoxidant is Al or its alloys; and deoxidn. is pref. controlled via the equation log(O) = -20600/T + A; where (O) is the dissolved O2 in ppm before casting: T is the steel temp. in degree K; and A is a function of the initial O2 content and the type and amt. of deoxidant used plus the injection time. A good surface finish can be obtd. despite the presence of numerous large sulphide inclusions in the steel.

Title: Spun filament felting - is constructed to have a higher shear resistance in one direction
Inventor: SCHNEIDER HEINRICH DIPL CHEM
IPC: D04H3/14
Filed: 1979-06-19
Abstract: In the manufacture of a thermoplastic spun felting, the material is formed from virtually continuous filaments deposited at random. The material has a higher shear resistance in one direction than in the other direction at right angles to it, and it is needle bonded. The fabric is drawn in the direction of lower shear resistance to 20-200% of its original length at a temperature of 85-25 degrees C below its crystallite melting point. In the other direction, of higher shear resistance, the dimensions are held firm or, at the same time, only altered by plus-or-minus 10% of the original length in that direction. The process gives a material with improved characteristics, particularly its behaviour when attached to a stentor frame.
Patent DE-2925742-A1 (DE)
Title: Yarn drying by circulation of heated compressed air - subsequently cooled by water spray to precipitate moisture
Inventor: AMELING BERNHARD
IPC: F26B21/08
Filed: 1979-06-26
Abstract: In a drying and finishing process for fibre and yarn packages whereby heated compressed air is circulated through the material, water vapour is precipitated from the air by cooling in a water spray, after which the air is re-heated before re-circulation. Waste water from other processes may be used for the cooling spray, alternatively, finishes may be applied to the yarn or fibre by adding the required chemicals, etc., to the spray. The re-circulated air has a controlled moisture content, to avoid over-drying the material, and leave it with a uniform moisture regain. The water spray is more effective and efficient than an indirect heat exchanger for cooling and drying the air-stream. The process allows the moisture content of the air, and the yarn, to be kept under control, and also enables the simultaneous application of finishes to the material.
