Patent DE-3303713-A1 (DE)
Title: Electrical machine having a stator winding which is constructed from integral coils
Inventor: SCHULER ROLAND
IPC: H02K11/26
Filed: 1983-02-04
Abstract: The stator windings of motors and generators having powers of a number of MW are normally constructed from integral coils whose weakest point, in insulation terms, is the winding insulation. In the event of voltage surges from the mains, said winding insulation is very highly stressed, particularly at the winding inputs, which leads to winding damage, so-called winding shorts. If an element which is "weak" in insulation terms is constructed parallel to the winding insulation on a short length in the winding overhang, that is to say at a point which is easily accessible for repair purposes, then surge voltage protection which is integrated in the winding is obtained which, although it does not prevent the local winding defect, limits the secondary damage to the machine and makes cost-effective repair possible. <IMAGE>

Patent DE-3404405-A1 (DE)
Title: Automatic fermenter pump
IPC: C02F3/28
Filed: 1984-02-08
Abstract: The fermenter pump comprises a casing, wherein there is a rotor on a shaft. The fermenter pump can be flanged as a component onto a digestion tank or a biogas apparatus. That side of the fermenter pump is used which has the orifice. At the top of the fermenter pump there is a gas outlet connection, and below this there is a connection piece. Through this connection piece, whose extension is the pipe, the liquid to be pumped is passed into the fermenter pump. Through a pipe arranged centrally in this connection piece, gas is likewise passed into this connection piece and thus into the fermenter pump. This biogas thus introduced can rise through this connection piece or nozzle orifice in the fermenter pump and set the rotor on the shaft in motion. Said gas rising in the fermenter pump, after moving the rotor and passing the baffle and deflector plate, can rise upwards. The biogas thus rising can escape from the surface of the liquid and then leave the fermenter pump at the gas outlet connection. The rotor, which rotates when the fermenter pump is operating, scoops liquid from the connection piece or pipe through the fermenter pump in the direction of the pump rotor and conveys this liquid through the orifice to that apparatus, for example a biogas installation, onto which the fermenter pump is flanged.

Title: Process for preparing prestressing assemblies built into a reinforced concrete component for grouting using a grouting composition
IPC: E04G21/12
Filed: 1984-05-09
Abstract: Process for preparing prestressing assemblies built into a reinforced concrete component comprising a prestressing tube and prestressing steels which are arranged therein and already prestressed for grouting using a grouting composition. A heated air current taken from an air compressor is transmitted through the prestressing tube and this air current treatment removes from the prestressing assembly water which has penetrated into the prestressing tube. A hot air current is used for this which has first been dried. This air current consequently has a predetermined value of air humidity upon entering the prestressing tube. The air humidity of the air current emerging from the prestressing tube is measured. It is compared with the predetermined value of air humidity. The air current treatment is completed only when the value of the air humidity of the air emerging from the prestressing tube virtually corresponds to the predetermined value of the air humidity of the entering air.

Title: Device for determining fine dust concentrations
Inventor: ARMBRUSTER LORENZ DIPL PHYS
IPC: G01N21/53
Filed: 1984-07-12
Abstract: The small and handy device for determining fine dust concentrations provides an annularly constructed measurement chamber with assigned Wood's tubes, a supply and measuring electronic system constructed in two parts with an analog part and a digital part, as well as a microprocessor, produced using C-MOS technology, and assigned DC/DC converters control modules for generating the required operating voltages. All the dust located in the measuring volume is illuminated by means of a monochromatic illuminating device in the wavelength region of 800-1000 nm, in order to guarantee perfect dust assessment of the fine, airborne dust which can get into the lungs. The scattered light of the particles is measured at an angle of exactly 70 DEG . The use of an exact measuring angle and the guidance of the illuminating and measuring beam by the use of lenses, diaphragms and suitable Wood's tubes renders it possible in the case of punctiform imaging of the measuring beam on a receiver to obtain a measuring chamber with a design that is very small, low in noise and streamlined. By minimising the energy requirement of the electronic system, it is possible to reduce the space requirement for the required accumulator, so that the latter can also be installed in the apparatus. The internal cycles during measurement, the measured value processing and the measured value display are controlled by a microprocessor which has a low power requirement. <IMAGE>
