Title: Removal of biological nitrogen from contaminated water, esp. from sludge treatment - by flowing water through nitrification bed reactor into which oxygen is introduced followed by entry into denitrification chamber
Inventor: BRAEUTIGAM HANS DR ING
IPC: C02F3/28
Filed: 1992-11-05
Abstract: In a procedure for separately eliminating biological nitrogen from contaminated water, the water flows downwards in a nitrification process through a reaction bed reactor into which oxygen is introduced at various levels. The water leaving the base of this reactor enters a denitrification chamber, from which it flows to an outlet point or is recycled to the nitrification process. Also claimed is an appts. for carrying out the procedure, consisting of a reactor (2) with a water inlet (6) at the top (3), a gas outlet (7) with a sepn. device (8), oxygen inlets (9), and a lower water outlet (10) connected to a denitrification chamber (11) with a water outlet (12). Oxygen is introduced in the form of oxygen-enriched air or technically pure oxygen. Denitrification is carried out using suspended or immobilised denitrification agents. A synthetic carbon cpd. or a natural product such as primary sludge, waste water, etc., acts as source of carbon for the denitrification agents. The evolved gas is removed from the top of the nitrification reactor. The gas outlet pipe (7) is provided with one or more pumps (15). The reactor outlet (10) is connected by a return line (16) and a pump (17) to the water inlet pipe (18). A pump (20) is provided in the denitrification chamber inlet pipe (19). The fresh water outlet (21) from the denitrification chamber (11) is connected to a vessel (23) which is linked by a recirculation pipe (24) and pump (25) back to the denitrification chamber, and by an outlet pipe (26) to the water outlet (12). This outlet pipe (26) is connected to the recirculation pipe (16). Two three-way valves (27,28) are provided in the recirculation pipe (16), one connected to the denitrification chamber inlet pipe (19) and one to a pipe (30) connected via a further three-way valve (29) to the water outlet pipe (26). USE/ADVANTAGE - Used esp. for treating water recovered from sludge handling processes. Nitrogen in the form of ammonium is reliably and economically removed from the water without prodn. of residual materials which must be disposed of separately.
Patent DE-4237616-A1 (DE)
Inventor: LANG WERNER
IPC: B43K8/10
Filed: 1992-11-06
Abstract: The invention(s) relate(s) to writing instruments and especially to capillary colorant reservoirs in said writing instruments. A process for producing said colorant reservoir is also proposed. The main problem in such colorant reservoirs is the storage time. During this time, the writing capacity of new writing instruments falls since the walls of the writing instruments are, if only slightly, permeable to solvents. In the long run a stored writing instrument thus dries out and loses the major proportion of its original writing capacity. To this end, an invention proposes to provide a colorant reservoir having an elongated reservoir body (20) made of fibrous material (21). It is surrounded by a sleeve (22) which is permeable to liquids and gases and gives the reservoir body (20) its shape. The colorant reservoir stores colorant to produce the (liquid) writing medium said colorant being stored between the fibres of the fibrous material (21) of the reservoir body (21) in dry form. A one or multi-part wick (1) projects from either side of the reservoir body (20). A process for producing said colorant reservoir is also proposed, according to which the elongated capillary fibrous body is surrounded by a gas and liquid-permeable but liquid-proof foil and the fibrous body thus surrounded is soaked in or with a colorant concentrate. The soaked fibrous body is drained off and dried. Then a one or multi-part rod-like wick (1) is introduced along it. The wick (1) is longer than the elongated fibrous body (20).

Title: Method for producing a bridge support and bridge support produced thereby
Inventor: HEINEN RICHARD DR
IPC: E02D23/02
Filed: 1993-06-26
Abstract: A bridge support (1) has, at its lower end founded under water, an impact protection (4) which surrounds it and is intended to protect the bridge support (1) from damage due to the impact of a ship. For this purpose, a caisson (8) is connected externally, via impact-yielding or impact-elastic connection elements (9), to a protective covering (10) spaced apart from the caisson. The annular space (11) between this protective covering (10) and the caisson (8) is sealed off at the underside, thus forming a floating body which enables floating transportation of the unit consisting of caisson (8) and impact protection (4) into the position of the bridge support (1) to be erected. <IMAGE>

Title: Method for determining the liquid level in aggressive and flowing media
Inventor: STACH HELMUT PROF DR
IPC: G01F23/24
Filed: 1993-08-12
Abstract: The invention relates to a method for determining the liquid level, in particular in chemical reactions in which there are aggressive and flowing media, on the basis of an electrical, temperature-dependent resistor string which is heated by a constant electric current flowing through it. According to the invention, a resistor string (for example a resistor wire) made of an electrically conductive material which is resistant to aggressive media is arranged in the reactor in such a way that the medium flows past said string predominantly in parallel. The resistor string, on which there are a plurality of pick-offs, is flowed through and heated up by a constant current. Differences in the thermal transfer coefficients lead to different cooling effects in the immersed and non-immersed string sections of the electrical resistor body. Because of the temperature dependence of the electrical resistance, the respective filling level can be determined therefrom via voltage measurements on the pick-offs.

Title: Converter for feeding fluorescent tubes for the illumination of railway carriages
Inventor: KHERMAYER FRANJO
IPC: H05B41/295
Filed: 1994-04-08
Abstract: The converter for feeding fluorescent tubes for the illumination of railway carriages solves the problem of feeding fluorescent tubes for the illumination of mobile and stationary objects from a DC source. The essence of the converter according to the invention resides in the fact that the inductance of the primary winding (N1) of the transformer (TR1) and of the capacitors (C1, C7) forms a tuned circuit during the starting phase of the fluorescent tube (FC), which tuned circuit, excited by a MOSFET transistor (T2), generates a positive half-cycle of a sinusoidal voltage. This voltage starts the fluorescent tube (FC) via the secondary winding, which is composed of the windings (N2, N3, N4, N5). After the start of the tube (FC), the tuned circuit is damped and feeds the fluorescent tube (FC) with a constant alternating current. The voltage for heating the cathodes of the tube (FC) is supplied by the windings (M2, M4) of the transformer (TR1); this voltage is reduced during the on-phase. The converter according to the invention is realised with only one MOSFET switching transistor, one transformer and one pulse-width modulator with the application of an adaptive feedback. The novel solution without using an inductor and a push-pull circuit is more economic than the known solutions and, at the same time, has excellent technical properties. <IMAGE>

Abstract: The contact device has at least one elongated laminate (3) for the electrically conductive connection of conductors (1, 2). An elongated integral spring (4), which is in the form of a ramp and has two relatively long limbs (4a) and two relatively short limbs (4b), which are preferably bent in a U-shape, is arranged on the laminate or on each laminate. The relatively long limbs (4a) run along the mutually averted side surfaces (3a) of the laminate (3), and the relatively short limbs (4b) engage over bearing surfaces (3f) of the laminate (3). The laminate or each laminate (3) has at least one hole (3h), which is in the form of a slot, in which it is held movably by a holder (5) which also acts on the relatively long limbs (4a) of the spring (4) when the contact device is in use, so that said relatively long limbs (4a) press the laminate (3) against the conductors (1, 2). The holder (5), which holds both at least one laminate (3) and the spring (4) associated with it makes it possible to assemble the contact device quickly and easily from a small number of parts and to match it to a large number of different conductor shapes. <IMAGE>
