Patent DE-3333369-A1 (DE)
Title: Method for calibrating a machining sensor
Inventor: KRACKE ALAN GLEN
IPC: G01B7/06
Filed: 1983-09-15
Abstract: Method for calibrating an analog machining sensor having a variable resistance, which is arranged on a surface. Adjoining the analog sensor, discrete machining sensors are applied with high positional accuracy with respect to a structural feature on the surface. When machining is performed, the circuit continuity of the discrete sensors is sequentially interrupted, while the height of the analog sensor is reduced and its resistance increases. Measurement of the resistance of the analog sensor at the instants at which the respective discrete sensors are interrupted yields values from which the position of the machined edge of the analog sensor can be very precisely determined with reference to the position of the structural feature on the surface.
Patent DE-3335117-A1 (DE)
Title: Infrared solid-state image sensor
Inventor: YUTANI NAOKI
IPC: H04N5/335
Filed: 1983-09-28
Abstract: A proposed infrared solid-state image sensor comprises a plurality of infrared sensor elements (100a), each of which has a p-type silicon substrate (1), a metallic electrode (3) which is connected to the silicon substrate (1) and defines a Schottky junction zone situated between them, and a p<+>-type region (11) situated in the region of the silicon substrate (1). The Schottky junction zone has a higher impurity concentration than that of the silicon substrate (1). Siting the p<+>-type region (11) having a higher impurity concentration at a region interfacing with the Schottky junction zone increases the magnitude of the electric field at the surface, thereby lowering the effective height of the Schottky barrier. As a consequence, the maximum wavelength of the light which can be detected with the infrared sensor element (100a) becomes longer. <IMAGE>

Patent DE-3401499-A1 (DE)
Title: High-temperature reactor with spherical fuel elements and a pressure boundary of the primary coolant circuit
Inventor: SCHOENING JOSEF DIPL ING DR
IPC: G21C1/24
Filed: 1984-01-18
Abstract: The invention relates to a high-temperature reactor with spherical fuel elements and a pressure boundary of the primary coolant circuit. The pressure boundary, which consists of a prestressed concrete pressure vessel with a metallic liner and of a plurality of penetrations sealed by means of closure devices, must be fail-safe during operation for safety reasons. In nuclear reactors with a steel pressure vessel, this is achieved by redundant measures, specifically by designing in accordance with basic safety, by quality control and by operational monitoring. According to the invention, the security against failure is achieved in the high-temperature reactor described above by the redundant construction of the components of the primary coolant circuit, as a result of which the abovenamed redundant measures (design in accordance with basic safety, quality control and operational monitoring) can be saved entirely or partially. In particular, in-service inspections are rendered superfluous as redundant measures, and it is not necessary to shut down the reactor. Since the loading and unloading of the core are performed during operation in a high-temperature reactor, this results in a higher degree of availability for this type of reactor.

Title: Process for the conversion of EDTA and sulphur-nitrogen compounds from waste waters of NOX scrubber units
Inventor: HOELTER HEINZ DIPL ING
IPC: B01D53/60
Filed: 1984-08-03
Abstract: The invention relates to a process for the conversion of EDTA and sulphur-nitrogen compounds and carboxylic acid compounds from waste waters of SO2 and NOX scrubber units. Because of the chlorine content of the coal, a part-amount of the water must be discharged in order to prevent salination of the scrubbing waters. This partial discharge of scrubbing water from the circulation also removes the additive EDTA and the sulphur-nitrogen compounds formed together with the water. In order to remedy this disadvantage, it is proposed according to the invention that a desired amount of waste water from the scrubbing water circulation of one or, simultaneously, of a plurality or of all scrubber stages is fed, via a pump, to a nozzle apparatus which opens in the hot region of the untreated gases, preferably in the region of the boiler, upstream and/or downstream of the electrostatic precipitator.

Title: Process for the continuous production of mouldings, in particular slabs, from a mixture of gypsum and fibre material and device for carrying out the process
IPC: B28B17/02
Filed: 1984-10-27
Abstract: The invention relates to a process for the continuous production of mouldings, in particular slabs, from a mixture of gypsum and fibre material. In a first mixing process, a metered amount of gypsum and fibre material is intimately mixed together, after which the mass of the dry gypsum/fibre material mixture is measured. The dry gypsum/fibre material mixture is moistened in a second mixing process with the metered addition of water corresponding to the measured mass of mixture. The moistened mixture is scattered on a substrate to form mouldings, after which the surfaces of the moulding are post-moistened and the moulding subsequently compacted. According to the invention, in order to obtain higher strengths, it is provided to subdivide the mass flow into partial mass flows separate from one another and to scatter the moulding in a plurality of layers, each partial mass flow forming a layer of the moulding. Each deposited layer is post-moistened with water, the total amount of the water added to a moulding being for example up to 25% above the stoichiometric quantity of water for setting the gypsum/fibre material mixture.
Patent DE-3442843-A1 (DE)
Title: Vacuum pump
Inventor: MASE MASAHIRO
IPC: F04D19/04
Filed: 1984-11-23
Abstract: The integrally constructed vacuum pump has a multiplicity of different types of pump stages (5, 6, 7) which are arranged in a casing (4) along a single shaft (1) from the inlet port side to the outlet port side. The pump comprises a spiral molecular pump stage (5) having a high compression ratio, a radial compressor stage (6) which operates in the viscous flow range, and a peripheral pump stage (7) or screw pump stage (19) which both operate optimally close to the shut-off point. The peripheral pump (7) or screw pump (19), which forms the last pump stage, may have a rotary section with a reduced diameter, owing to the pump type used. This reduces the friction loss and thus the power required to operate the pump, leading to increased pump efficiency. <IMAGE>

Patent DE-3535311-A1 (DE)
Title: Method of deriving a scanning cycle
Inventor: NOSKE REINER
IPC: H04N9/89
Filed: 1985-10-03
Abstract: A method of deriving the scanning cycle for reproduction of magnetically recorded video signals is given. To correct timing errors of these video signals, they are converted from analogue to digital and written into a buffer memory. The writing cycle and the scanning cycle for the analogue-digital conversion vary in the rhythm of the timing error which occurs in the video signals. They are read from this buffer memory with an extremely stable cycle. Instead of using a start-stop oscillator triggered by high frequency pulses, it is proposed that the scanning cycle for the analogue-digital conversion and for writing the analogue-digital converted video signals into the read-write memory should be derived by multiplying and then dividing a very stable output cycle. For this purpose, reset pulses which have the same timing errors as the video signals to be processed are fed to a divider.
