Title: Centrifugal pump
Inventor: BLUECHER LUDWIG
IPC: F04D29/12
Filed: 1988-07-08
Abstract: In known centrifugal pumps which have a pump shaft which is connected at one of its ends to a drive and at its other end carries at least one impeller, a sealing arrangement is provided for sealing the pump shaft. The delivery of the delivery medium is performed in such a way that the delivery medium is present at its highest pressure at parts of the sealing arrangement. This causes increased wear in the case of an abrasive delivery medium. The novel centrifugal pump has, by contrast, a delivery direction in the case of which the delivery is performed from a suction-side delivery compartment (22) to a pressure-side delivery compartment (29) which is arranged on the side of the pump housing (12) averted from the sealing arrangement (11). The sealing arrangement (11) is thus not exposed to a pressure load. The parts of the sealing arrangement (11) are arranged outside the suction-side delivery chamber (22). Delivery of abrasive media, in particular metallic paint for painting motor vehicles. <IMAGE>

Inventor: DOERRIE HORST
IPC: H01Q1/12
Filed: 1988-07-19
Abstract: The object is to improve a known vehicle window antennae, having a dipole and a conductor running parallel thereto, as a counterweight to the dipole, such that the antennae is shorter, the conductor requires no direct connection to the vehicle bodywork and such that the conductor configuration is relatively simple and can easily be implemented. The solution is for each of the dipole halves (13, 14) to consist of a V-shaped conductor and for the dipole halves, having a geometric length l1 =  lambda /4, to be connected to one another at their mutually facing ends, via a straight line piece (17). The conductor (18), running parallel to the longitudinal extent of the dipole (12), is straight and is insulated from the dipole and from the vehicle bodywork. The conductor has a length l4 <  lambda /2, where  lambda corresponds to the mean operating wavelength. A preferred field of application for the vehicle window antennae is a UHF radio antennae for a radio telephone. <IMAGE>

Title: Process and plant for treating surface water polluted with deicing compositions
Inventor: MORSZECK THOMAS DIPL ING
IPC: G01N33/18
Filed: 1988-12-14
Abstract: In the case of surface water polluted with deicing compositions, as occurs, e.g., with air traffic areas in freezing periods by the use of chemical sprays, there is the problem of separating off surface water polluted in this way prior to introduction into receiving water. In order to achieve this, the surface water is tested for contents of environmentally harmful substances in on-line operation and when predetermined limit values are exceeded, it is diverted into a treatment plant. Because of the delay in measurement to which the highly water-hazarding contents of, e.g., nitrogen are subject, there is the possibility of polluted surface water still passing into the receiving water during a certain transition time. In order to prevent this, a further parameter, e.g. organic carbon (TOC) is evaluated which indicates pollution, e.g. with nitrogen, but which can be detected within a considerably shorter time. Furthermore, the surface water can be further conducted via a storage line in order to bridge even the delay in measurement still remaining.
