Title: Friction spinning unit avoiding abrupt stops - utilises friction disc for fibre delivery to yarn formation groove
Inventor: HARTEL ROBERT DR ING
IPC: D01H4/38
Filed: 1992-07-20
Abstract: A process of friction spinning employs a rotary delivery disc to lay fibre into a spin formation. The fibres are separated by an opening roll, transported by the delivery disc in a tangential position by means of centrifugal force and an airstream. The speed of delivery is at least equal to the supply of fibre. The spun yarn is then withdrawn in a reverse direction. Also claimed is the  appts. used. ADVANTAGE - The process improves the formation of the yarn, in that the fibres bind together better. The method of fibre delivery avoids an abrupt stop, which would be the case with airflow alone.

Title: Drive for vertical pillar drill - has vertically-sliding threaded spindle for chuck, engaging with pair of worm wheels whose horizontal axles can be braked
Inventor: JANG KWAN SOON
IPC: B23Q5/52
Filed: 1992-09-25
Abstract: The drill has a chuck (16) attached to a belt-driven spindle (6), the drive for the spindle being a motor at the rear of the top of the tool. The spindle slides vertically within the driving pulley (11) with the help of a return spring (12). Vertical movement is obtained by a sleeve (14) which slides vertically but does not rotate. The spindle is threaded and engages with two parallel worm wheels (9) with horizontal axles (10). These axles can be braked either directly or indirectly, the brakes being band brakes. As the worm wheels are braked, the driving spindle speed is reduced, without preventing its vertical movement. A foot pedal can facilitate the drilling operations. ADVANTAGE - Suitable for repeated similar drilling operations, with large holes being drilled as easily as small holes.

Patent DE-4239487-A1 (DE)
Inventor: BAUR KARL GERHARD DR
IPC: C02F11/08
Filed: 1992-11-25
Abstract: Oxidation of ammonium ions and organic carbon in ammonium-ion-containing and organic carbon-containing waste waters (effluents) by nitric acid at 100 to 350@C, in that the molar ratio of organic carbon to ammonium nitrogen is established at a range of 0.3:1 to 4:1 by addition of organic carbon or ammonium nitrogen. In a preferred embodiment which is reproduced by way of example in the figure, the waste water, which can be enriched, depending on the TOC content, with organic carbon, is transported via the feedline (1), possibly from an intermediate tank (2), by a pump (3) through a heat exchanger (4) in which it is preheated to, for example, 270@C. The preheated waste water is then heated by direct feed of 100 bar high-pressure steam via feedline (5) or by indirect heating to 290@C. After establishing the nitric acid concentration necessary for the ammonium degradation, e.g. via a feedline (6) in the waste water at 290@C, this is conveyed through a reactor (7) without back-mixing (e.g. a tubular reactor having internals and which is clad with titanium). After a residence time of, for example, 5 to 10 min, the reaction solution is cooled in counter-current with the feed and is depressurised in a separator (8). The waste water is removed via a line (9), via an intermediate tank (10) and a heat exchanger (11). <IMAGE>

Title: Methyl-hydroxyalkyl-cellulose ethers prodn. - with recovery of useful soluble short-chain cellulose ethers by ultra- or micro-filtration of the wash water from purification
Inventor: EVERTS DIRK DIPL ING
IPC: C02F1/44
Filed: 1992-12-08
Abstract: The prepn. of methyl-hydroxyalkyl-cellulose ethers (I) is carried out by reaction of cellulose with alkali, etherification, washing the prod. with water and recovering the soluble short-chain cellulose ethers (II) from the washings. In this process, the wash water (contg. dissolved NaCl and organic by-prods.) is passed through an ultra- or micro-filtration membrane at a temp. between 70 deg.C and the b.pt. of the wash water, so that the concn. of (II) in the water is increased to more than 10 g/l (measured as carbohydrates), and the pptd. solid (II) is added to the washed (I) or worked up as a separate prod. by further drying. Pref., membrane filtration is carried out at not more than 15 deg.C below the b.pt. of the wash water, pref. with the wash water at 85-150 deg.C. Filtration is carried out, pref. in several stages, at an overflow rate of 2-4 m/sec. in the membrane, using membranes with a cut-off limit of 5000 Daltons and pore size up to 2 microns, so that the concn. of (II) is increased to 30-120 g/l. ADVANTAGE - The process enables a high proportion of the cellulose ethers in the wash water to be recovered; this is esp. useful where there are large amts. of (II) in the washings, as when using wood pulp as starting material or in the prodn. of low-viscosity (I), and with washings contg. large amts. of NaCl. Other organic impurities such as glycols, polyglycols and low mol.wt. oligomers are removed with the permeate in the membrane filtration, and the final effluent contains much less of the poorly biodegradable (II).

Title: Turn-on control method and turn-on control circuit for an invertor coupling a solar generator to the electricity mains
Inventor: BLEIL ANDREAS
IPC: H02J5/00
Filed: 1993-08-25
Abstract: Known turn-on control methods and turn-on control circuits provide the monitoring of the solar generator no-load voltage (open-circuit voltage), the invertor being activated when this voltage exceeds a predetermined threshold value. The turn-on accuracy is unsatisfactory because the no-load voltage is strongly dependent on the module temperature. In contrast, the novel method provides the measurement of the short-circuit current of the solar generator (1) and the stipulation of a corresponding short-circuit current threshold value, the invertor being turned on in the event of this threshold value being exceeded. A circuit relating to this contains a short circuit (Ki) with a short-circuit current measuring element (2) as well as an evaluation unit (10, 3, 4) for identifying when the threshold value is exceeded and the invertor is activated. On account of the comparatively low dependence of the short-circuit current on the temperature, very accurately timed turning-on of the invertor is produced for varying solar module temperatures. Use in photovoltaic installations which feed power to the electricity mains. <IMAGE>
