Patent DE-3123530-A1 (DE)
Title: "Method and appliance for preparing and compressing an inert gas"
Inventor: WINTER KARL DIPL PHYS
IPC: B01J7/00
Filed: 1981-06-13
Abstract: When inerting containers, as much inert gas as possible should expediently be available in as short a time as possible. Sensibly, the inert gas should be stored in advance. Storage is generally done under pressure. It is therefore necessary to compress the inert gas after it has been generated. The invention proposes to employ, as the inert gas generator, an internal-combustion engine which drives a compressor which compresses the exhaust gas of the internal-combustion engine. Therefore, no additional energy is required for compression. Moreover, during the compression in conjunction with cooling, most of the water is condensed, so that the inert gas is produced in very dry form.

Title: Method and device for the interpolation of signals in high-resolution measuring systems
Inventor: LINDNER MANFRED DIPL ING
IPC: H03M1/00
Filed: 1981-07-02
Abstract: The method and the device have the aim to reduce the complexity and to increase the measuring accuracy. The object consists in creating a simple method of interpolation and an interpolation device without microprocessor and phase-cyclic interpolation for connection to indicators on a counter basis. In accordance with the method, linear voltage signals are generated by addition of the output signals of the photoreceivers for each quadrant in an analog adding circuit, which signals are digitised under quadrant control in a voltage/frequency converter. These digitised signals are then supplied to a frequency/digital converter in which the frequency of the output signals, which is proportional to the voltage, is converted into counting pulses and counted in the counter. In the device, one operational amplifier is provided for each quadrant of the output signal for analog addition and is connected via an analog multiplexer to a voltage/frequency converter which is followed by a frequency/digital converter. <IMAGE>

Title: Transport system for the blueprint material in blueprinting machines
Inventor: SPORK FRANZ
IPC: G03B27/24
Filed: 1982-03-25
Abstract: In a blueprinting machine, in which the original sheet and the copy sheet traverse an exposure station while situated one upon another and are reseparated from one another in a following separating station in order to feed the copy sheet to the developing station, there is arranged in the advance path of the original sheet a sensor which senses the front edge of the original sheet and, with the aid of a control circuit and taking account of the rate of advance of the blueprint material does not switch on the separating box, which belongs to the separating station and detaches the original sheet from the copy sheet, until the original sheet enters the separating station with its front edge. This leads to reduction in the air turnover, and thus both in the incidence of noise and in the risk of developer gas penetrating into the space surrounding the blueprinting machine.

Title: Oxygen-active redundancy method for a combustion process
Inventor: SAKOBIELSKI WILHELM
IPC: F23C99/00
Filed: 1982-06-28
Abstract: The present invention is concerned with combustion processes of motor operation and heat production practice which, with reference to their predetermined machine element relationships, require heating oils, liquid or gaseous internal combustion materials as operating media. Without changes to the respective machine element relationships, and without consideration of the quality of the respective operating media, a respective combustion process is to be achieved which predominantly takes place on the chemically exothermic reaction side, so that in possible circumstances a combustion/energy conversion with the best possible efficiency remains ensured. The minimum principle of the endothermic reaction phase then guarantees that few harmful or potentially harmful combustion products or air pollutants arise. In order to achieve the required high combustion rate, a functionally participatory oxygen carrier reserve is associated with the respective machine element relationships. An oxygen carrier (nitrous oxide N2O) is added to the conventional fuel-air mixture by an injector principle, so that a fuel-air/oxygen mixture quality of an especial kind is present. In addition it is provided that the given air filter in the respective machine element relationship can be replaced by an air pollutant filter. The air pollution filter is a modification of a conventional respiratory protection filter. Its use is valid especially in smog-like environmental conditions and/or in ABC [atomic, biological, chemical] catastrophes.

Title: Process for the preparation of 3,4-dihydro- alpha -pyrones
Inventor: SCHMIDT HANS-GEORG DIPL CHEM D
IPC: C07D309/32
Filed: 1982-12-04
Abstract: The present invention deals with the preparation of 3,4-dihydro- alpha -pyrones, which can optionally also be alkyl-substituted in the 3- and/or 4-position. These pyrones are prepared according to the invention by thermolysis of 4,5-epoxypentanecarboxylic acid esters which are optionally alkyl-substituted in the 2- and/or 3-position, or of 4-formylbutyric acid derivatives which are optionally alkyl-substituted in the 2- and/or 3-position. These 4-formylbutyric acid derivatives are formed as isolable intermediates when 4,5-epoxypentanecarboxylic acid or its esters are employed as starting materials and the thermolysis is preferably carried out at 350 to 450 DEG C. The formylbutyric acid derivatives isolable as intermediates are compounds unknown hitherto. The thermolysis for the preparation of the  alpha -pyrones is preferably carried out in a temperature range between 250 and 350 DEG C and in the presence of high-surface area silicate materials, such as montmorillonite or zeolite, or of alumina. When the formylbutyric acids are employed as starting materials, the formation of the dihydropyrones takes place even at temperatures from 30 DEG C, particularly if acidic compounds are employed as catalysts.

IPC: B22D11/00
Filed: 1983-01-18
Abstract: Small steel plants for the production of steel bars have rapidly met with widespread approval. For technical reasons, and with the assumptions which generally exist, they are, however, used only for a production of more than 100,000 tonnes/year. Market studies show the need for small steel plants of 10,000 tonnes to 100,000 tonnes/year. These small steel plants can be set up if, with the use of the combination concept of the invention     - the assumptions which generally exist are corrected, - the technological consequences resulting therefrom are used for the overall optimisation of known plants. e
