Title: Process for the thermal aftertreatment of drawn synthetic threads shaped by compression.
IPC: D02G1/16
Filed: 1977-07-07
Abstract: Compression-crimped synthetic silk consisting of thermoplastic is subjected in thread-plug form to thermal aftertreatment. For this purpose, an aftertreatment drum (14) of adjustable rotational speed and at least one compression chamber (10) are used. A delivery unit (11) of adjustable rotational speed, arranged between the compression chamber or compression chambers and the aftertreatment drum, serves for conveying the thread plug or thread plugs of crimped multifilament synthetic silk, formed in each compression chamber, out of the compression chamber or compression chambers and, after passage through a free zone, towards the aftertreatment drum. Once arrived there, each continuously delivered thread plug runs in an approximately tangential direction onto the gas-permeable casing of the rotating aftertreatment drum cylinder and is transported through the aftertreatment zone by the latter in the form of helical thread-plug turns lying closely to one another and free of radial pressure. The thread material is either heated or cooled. The gaseous treatment medium flows through the helical thread plug turns of the treatment material in the radial direction. The opening of the thread plug or thread plugs to form crimped synthetic threads takes place at the end of the aftertreatment drum. A tension-free, uniform thermal treatment of the synthetic silk delivered at a high feed speed, along with a sufficient dwell time, is made possible in this way. <IMAGE>

Title: Liquid organo-mineral fertilizer based on molasses residues and process for preparing thereof
Inventor: HOFSCHNEIDER MIROSLAV RNDR
IPC: C05B7/00
Filed: 1992-08-21
Abstract: Liq. organic-mineral fertiliser is derived from a mixt. of conc. molasses vinasse and ammonium salts contg. on a dry basis 40-80 wt.% of molasses vinasse having a density of 1.2-1.45 g/ml and 20-60 wt.% of an ammonium phosphate ammonium nitrate or ammonium sulphate. The ammonium salt is pref. ammonium hydrogen phosphate, ammonium dihydrogen phosphate and/or ammonium phosphate. USE/ADVANTAGE - The fertilizer contains inorganic and organic nitrogen, potassium and soluble phosphorus in a measured ratio which can be varied to suit the nutrient quality of soil to be treated. It is environmentally harmless, is used esp. as a fine spray over the entire growing period of plants and improves soil structure (e.g. by promoting degradation of organic material).
