Filed: 1981-07-18
Abstract: Method for determining waste water parameters from the oxygen consumption of a waste water, in particular for the purpose of process control and/or monitoring a biological sewage treatment plant. The activated sludge suspension to be tested is placed into a reaction vessel in the exhausted state. The following measurement phases are then carried out:   a) The oxygen consumption of the batch is measured over a period T0, which is longer than a normal consumption curve, the oxygen content of the batch being constantly kept above 0.5 mg/l and below 6.5 mg/l;   b) A sample of waste water having unknown waste water loading is added and the oxygen consumption in the reaction vessel is measured under the same conditions as in measurement phase a) over the period T0. The difference between the oxygen consumption values of measurement phase b) and measurement phase a) is used as a measure of the waste water loading of the sample, by forming a ratio between it and a corresponding value determined on a waste water of known waste water loading. In addition, an apparatus for carrying out the method is proposed.

Title: Process for producing a container
Inventor: ARTUSI ALDO
IPC: B65F1/02
Filed: 1982-04-01
Abstract: In a process for producing a container having a bottom fixed unreleasably to side walls and/or a lid, the side walls, lid and/or bottom, after being removed from their transport packaging or the like, are joined together and connected unreleasably to one another by means of catch members. The side walls are formed by a material strip, from which tabs are bent via bending lines and are introduced into indentations of the lid and/or bottom and are retained there underneath by catch strips. Embossed in the lid and/or bottom is a semi-circular predetermined breaking line which separates a closure of an orifice, the semi-circle of the predetermined breaking lines being connected by an indentation in the lid serving as a hinge. In a container produced by this process, the material strip (5) has an approximately rectangular blank and four bending lines (6) which intersect its axis (A) and which form the side walls (7), there being formed on one side wall (7) in a manner separated by a bending line (6) a tongue (8) which is fixed to the band edge (31) located opposite it. Furthermore, bending lines (9) arranged parallel to the axis (A) and at the edge separate tabs (10) from the side walls (7). For receiving these, the lid (2) and/or bottom (3) have indentations (24). For this, there are formed in the plane of an inner face (F) in an edge wall (24) catch strips (26) which, when the container (R) is being assembled, engage underneath the tabs (10) bent out of the plane of the side walls (7) by more than 90 DEG . The container can be used both as a dispenser for small medical instruments and, after being emptied, as a waste container.

Title: Switching rail in conjunction with a relay
Inventor: GRUHN WOLFGANG
IPC: A63H19/32
Filed: 1982-10-21
Abstract: An application for the granting of a patent is submitted for a "switching rail in conjunction with a relay". The switching rail serves for automatically reversing the polarity in a track system of electrical DC model railways when inverted figures are used which permit the track to be travelled over in the opposite direction. The necessary reversal of polarity of the system for the unimpeded continued travel of a train occurs here with the aid of the switching rail by said rail being travelled over, without any manual intervention being required. An additional possibility - the fully automatic bypassing of suitable track figures in alternating direction - is provided by the use of switching rails which, in a double function, can automatically switch over points; in this way an interesting and expandable model railway operation can be realised. Expenditure is low and effective.
Patent DE-3239605-A1 (DE)
Title: Process for the combined preparation of ammonia and urea
Inventor: SCHRAMM WALTER
IPC: C07C273/10
Filed: 1982-10-26
Abstract: A process for the combined preparation of ammonia and urea is described. An ammonia synthesis gas substantially comprising hydrogen, nitrogen and carbon dioxide is subjected to elevated-pressure scrubbing using a solvent having a physical action at temperatures of at most ambient temperature in order to remove acid impurities, in particular carbon dioxide. The loaded solvent is partially let down for removing co-absorbed inert gases by gassing, then regenerated without pressure and returned to the elevated-pressure scrubbing, and the carbon dioxide released during regeneration is used for the urea synthesis. In order to enable this carbon dioxide to be passed on to the urea plant in an energy-saving manner in pre-pressurised form, it is proposed to bring the pressure above the loaded solvent after the partial depressurisation to an intermediate value, to heat the loaded solvent in order to remove some of the carbon dioxide by gassing, and to subject the solvent partially regenerated in this manner to the last pressure-less regeneration step, and to cool the carbon dioxide removed by gassing during heating and discharge it at the intermediate pressure.

Title: System for producing a partial vacuum in an internal combustion engine
Inventor: WIELAND ALFRED DIPL ING
IPC: F02B3/06
Filed: 1983-07-09
Abstract: In passenger vehicles with diesel engines, partial-vacuum pumps which are usually driven by the diesel engine are used to produce a partial vacuum for partial-vacuum-actuated brake boosters. The said partial-vacuum pumps are relatively expensive, consume energy unnecessarily and are subject to wear which adversely affects safety.   According to the invention, these disadvantages are eliminated by means of a system for producing a partial vacuum, in which at least one cylinder of the diesel engine assumes the function of a partial- vacuum pump when the partial vacuum in the brake booster is insufficient in that a restrictor element is arranged in the air- intake channel of this cylinder, in that the partial-vacuum line of the brake booster is connected to the air-intake channel between the restrictor element and the cylinder, and in that the restrictor element closes the air-intake channel when the partial vacuum in the brake booster is insufficient and opens it when the partial vacuum is sufficient. The essential features of the invention can be seen in Fig. 1. <IMAGE>

Title: Drawing unit for fibre-spinning machines
Inventor: EICH EDWIN K
IPC: D01H5/26
Filed: 1983-07-15
Abstract: The invention relates to a drawing unit for fibre-spinning machines, having a drawing plate and a drawing lower apron and/or upper apron, between which the fibres are guided. For the easy exchange of the lower apron, there is arranged between a driving apron and an upper apron a roller bridge having at least two apron guide rollers of small diameter, on which an endless lower apron lies. This ensures that the driving apron is designed only as a frictional drive means for the lower apron on the rollers of the roller bridge, for which purpose the working cylinder is driven for a direction of rotation counter to the working flow. The mounting of the endless lower apron can thereby be carried out easily and quickly. In particular, the lower apron now seated on the roller bridge can be exchanged in the same way as the upper apron, that is to say the endlessly ground apron is pulled onto the roller bridge, the exchange already being concluded thereby.

Title: Galvanised insulating pipe and a method for its manufacture
Inventor: FLENDER HANS
IPC: F16L59/18
Filed: 1983-08-06
Abstract: A galvanised insulating pipe 1 having an inner pipe 2 which serves for conducting media is surrounded, at least over most of its length, by a jacket pipe 3 at a radial distance therefrom. The jacket pipe 3 is welded, at least at its ends, to a supporting ring 12, which in turn is joined to the inner pipe 2 in a weld joint sealed to water vapour. The space defined between the inner pipe 2, the jacket pipe 3 and the supporting rings 12 is filled with foamed plastic 16. The supporting rings 12 consist of shaped parts 6 which have a radial wall portion 13, the material thickness of which is approximately the same as the wall thickness of the inner pipe 2. The relatively low material thickness of the radial wall portion 13 avoids, on the one hand when galvanising the insulating pipes 1, damaging thermal stresses between the inner pipe 2 and the jacket pipe 3 and reduces, on the other hand when the insulating pipes 1 are in use, the formation of excessive thermal bridges between the inner pipe 2 and the outer pipe 3. <IMAGE>
