Title: Process and device for the biological purification of waste water
Inventor: MORPER MANFRED DR
IPC: C02F3/12
Filed: 1981-09-14
Abstract: A process and a device are described for the biological purification of, in particular, highly polluted waste water containing organic and nitrogen-rich compounds, in which after oxidation of the carbon compounds, the nitrogen-rich compounds are nitrified in a nitrification step. The nitrate-forming bacteria grow only very slowly in comparison to the bacteria degrading carbon compounds and may be easily inactivated by a critical waste water property. The recovery of complete nitrification after an interference, for example increased ammonium concentration, takes a long time. To overcome these disadvantages it is proposed that a side nitrification step is operated, in parallel to the nitrification step, at a low loading so that a nitrate-forming activated sludge is continuously formed in this, and that the nitrate-forming activated sludge of the side nitrification step is transferred, as required, into the nitrification step, part of the nitrate-forming activated sludge being retained in the side nitrification step for the formation of a new reserve of nitrate-forming bacteria. To form a reserve of nitrate-forming bacteria in the side nitrification step, at least part of the time a small part stream of the waste water to be nitrified and/or a part stream, not potentially harmful to nitrate-forming bacteria, of a foreign waste water is passed through the side nitrification step.

Filed: 1982-03-02
Abstract: A coaxial low-pass filter (7) or a contactless short-circuiting slide, in each case in a coaxial design, is characterised in that capacitance-increasing elements (7a, 7b) are constructed integrally with the inner conductor (12). The outline surfaces of the elements (7a, 7b) are gold-plated and are provided with a dip-varnish (11). The region between the elements (7a, 7b) was not reduced to the diameter of the inner conductor (12) by metal-cutting machining on a lathe until the dip-varnish (11) had been applied, which region was subsequently gold-plated together with the end surfaces of the elements (7a, 7b), the dip-varnish (11) being used as a covering. The low-pass filter (7) or contactless short-circuiting slide can be produced easily and is resistant to high acceleration, so that it is particularly suitable for installation in acceleration-resistant microwave oscillators or for intermediate-frequency extraction in mixers. <IMAGE>

Title: Device for receiver-end phase synchronisation of the sampling clock with the phase angle of the characters of a received time division multiplex character stream
Inventor: HENTSCHKE SIEGBERT DR ING
IPC: H04J3/06
Filed: 1982-07-21
Abstract: To synchronise the phase angle of the sampling clock for a received character stream in a receiver of a digital data transmission path, where the character stream contains a periodically recurring frame alignment signal, a device is indicated which, through cross-correlation of the received character stream sampled with the existing sampling clock with the frame alignment signal stored at the receiving end, determines the frame clock by identifying the maxima of the cross-correlation function recurring at intervals of the frame period. The cross-correlation function (K(i)) is now also used according to the invention to re-adjust the phase of the sampling clock by deriving the re-adjustment information ( DELTA P) for the phase re-adjustment circuit (7, 8, 9) from values of the correlation function in the vicinity of the periodically recurring maximum. For this purpose, the difference ( DELTA Ki0) is formed (4) from the values (K(i0-1), K(i0+1)) adjacent to the maximum (K(i0)) and is then smoothed in a smoothing accumulator (6) and quantised. The new synchronisation device thus forms a digital phase-locked loop for frame and character synchronisation which is particularly suitable for processing severely distorted received characters. <IMAGE>

IPC: B62B3/18
Filed: 1982-09-08
Abstract: Shopping trolleys are known which have a storage shelf which is supported on the basket and on the flap which ends at the rear wall of the basket, for the purpose of securely transporting drinks crates. In shopping trolleys of this type, the storage shelf must firstly be manually moved into a space-saving position if a plurality of such trolleys are to be pushed one into the other. In order to avoid this disadvantage, the invention proposes a shopping trolley (1) in which the storage shelf (13) is supported via stops (25) which are arranged on the side walls (3') of the basket (3), grooves (17) which are larger than the vertical projection of the stops (25) assigned to them being provided on the longitudinal sides (16) of the storage shelf (13). The grooves (17) permit the storage shelf (13) to be folded down. In the position of use of the storage shelf (13), the grooves (17) are located in the region between the stops (25) and the pivot axis (14) of the storage shelf (13). By means of this arrangement, shopping trolleys (1) can be pushed one into the other without additional manoeuvres, irrespective of whether the storage shelf (13) is in the position of use or position of rest. <IMAGE>

Title: Process for producing calcium aluminate slag in the blast furnace with simultaneous production of crude iron
Inventor: STAEDING WILHELM
IPC: C21B5/04
Filed: 1983-01-14
Abstract: The invention relates to a process for producing fused alumina cement and crude iron in the blast furnace. This hitherto known process is based on bauxite as the alumina carrier and is relatively expensive because, corresponding to a large quantity of slag per tonne of crude iron, the coke consumption is very high. Above all, however, operating failures occur due to the formation of titanium carbide encrustations on the blast furnace hearth. The invention eliminates the operating failures on the one hand and lowers the costs on the other hand by using an alumina carrier with more than 70% of Al2O3 and, as the remainder, predominantly CaO and, if desired, with a lower SiO2 content. This is done with the proviso that a silicon reduction takes place which leads to an Si content of 2.2 to 4% in the crude iron, while the CaO/SiO2 ratio in the slag is between 5 and 20.

Patent DE-3309901-A1 (DE)
Title: Contact tube
Inventor: PACHE NORBERT
IPC: B23K9/12
Filed: 1983-03-18
Abstract: The present invention relates to a contact tube for gas-shielded-arc welding in order to guide the welding wire and transfer the current from the contact tube to the welding wire, which is realised in a known manner by a contact tube in which the guide bore is 0.2 mm larger than the wire to be welded. The wire therefore has no exact guidance, and the discharge direction of the wire from the contact tube changes. The poor bearing of the wire against the wall of the bore leads to an undefined current transfer. The result of this is that the striking characteristic is considerably impaired and the life of the contact tube is reduced. In order to remove these shortcomings, the invention proposes to fit a pressure mechanism into the contact tube, which pressure mechanism presses the welding wire over an optimum section against the current-carrying bore wall of the contact tube so that a defined current transfer, exact striking of the arc and effective guidance of the welding wire are achieved.
