Patent DE-3238626-A1 (DE)
Title: Pipe with cleaning shaft
Inventor: KESSEL BERNHARD
IPC: E03F7/04
Filed: 1982-10-19
Abstract: The invention relates to a pipe with at least one automatic backflow-prevention device and a cleaning opening which is closed by a cover on which a manually actuable locking member for moving and fixing the backflow-prevention device is mounted, which locking member influences the backflow-prevention device only in a certain position. With this type of cleaning pipe, e.g. in cellar outlets, it has hitherto been necessary in the event of danger to close and block and then reopen the closure member manually. If the building stood empty or the responsible person was absent, the locking member could not be operated properly. According to the invention, provision is now made for an electrical actuator for the locking member to be mounted on the cover and coupled to the locking member so as to transmit rotary motion. In addition or as an alternative to the manual actuation of the locking member, the actuating drive adjusts the locking member as required, such that the closure member is either brought into its closing position and blocked thereat, or that the locking member passes into its position of non-engagement in which it does not influence the working cycle of the closure member.

Patent DE-3330023-A1 (DE)
Inventor: SCHEWE HERBERT DR
IPC: G11B5/127
Filed: 1983-08-19
Abstract: A combined magnetic write and read head for a recording medium to be magnetized perpendicularly comprises a magnetic conductor body for carrying the magnetic flux, the conductor body having two pole legs which are arranged one behind the other in the direction of relative motion of the head and medium and having a predetermined distance from each other. At least one coil winding is associated with the conductor body. In order to reduce problems regarding the mechanical design of such a head and to make possible at the same time a switchable write and read function having high efficiency, a separate coil winding is associated with each pole leg. The flux conduction directions in the pole legs are adjustable for the write function by means of the separate coil windings such that the flux directions extend, at the ends of the pole legs facing the recording medium, parallel at least to a high degree. Secondly, the magnetic fluxes in the pole legs may be adjusted in such a manner that, at the ends of the pole legs facing the recording medium, the magnetic flux in one of the pole legs is smaller and of a direction opposed to that of the magnetic flux in the other pole leg.

Title: Circuit arrangement for supplying electrical DC load arrangements
Inventor: KUPKA DETLEF DIPL ING
IPC: H02H3/087
Filed: 1983-08-19
Abstract: The invention relates to a circuit arrangement for supplying electrical load arrangements, which contains a supply circuit and a protection device which limits the current. In such a circuit arrangement, it is intended to achieve a limitation of the current in the dynamic short-circuit case without this being linked with an unacceptably high voltage drop at rated load. To this end, the invention provides that the protection device contain a current-limiting resistor (37) which is bridged by the source-drain junction of a power field-effect transistor (36). The control electrode of the field-effect transistor (36) is connected via a bias resistor (35) to the switching-on potential and via a threshold circuit to a further resistor. A zener diode (31), in particular, is used as the threshold circuit. The circuit arrangement can be used advantageously in remote supply apparatuses which are used for the DC series supply of information-transmission paths. <IMAGE>

Title: Snail-repelling bed surround
Inventor: KISSEL KORNELIUS
IPC: A01G13/10
Filed: 1983-10-05
Abstract: In horticulture, it is difficult to keep the "snail" pest away from the plantations without using poison. The invention solves this problem in a natural manner similar to thorny stems, such as e.g. on the rose. According to the drawing, the plantation to be protected is surrounded by a strip fitted with spines. The snails avoid such paths because the spine points do not offer them the adhesive surface necessary for crawling over. <IMAGE>

The carrier spindle (1) consists of a carrying arm (4) mounted in a cantilevered manner, of force-measuring devices (5, 6) which are fastened to the carrying arm (4), and of a bobbin carrier (9) which is designed as a carrying shell and which extends over the length of the carrying arm (4) and rests on the measuring knife edges (7, 8) of the force-measuring devices (5, 6). The entire constructional unit composed of a carrying arm (4), of the force-measuring devices (5, 6) and of the bobbin carrier (9) is located within an enveloping circle, the diameter of which is no larger than the inside diameter of the tubes (12) of the bobbins (13) to be handled. A pushing-out device (11), which is movable in the longitudinal direction of the carrying arm (4), serves for pushing off a plurality of bobbins (13) in succession. A method making it possible to determine not only the sum of the bobbin weights, but also the individual weights is also described. <IMAGE>

Title: Method and circuit arrangement for cancelling crosstalk and/or echo signals
Inventor: SCHENK HEINRICH DR ING
IPC: H04B3/23
Filed: 1983-12-01
Abstract: In an adaptive crosstalk and/or echo signal cancelling circuit arranged in parallel with a hybrid circuit on the four-wire side, with a variable filter and a cancellation signal combination component, the cancellation signal is formed depending on the difference - averaged if necessary - between the discriminator output signal, formed following the signal cancellation and in connection with adaptive signal equalisation, and the discriminator input signal by setting the filter coefficients, in the case of a significant difference - averaged if necessary - between the discriminator input signal and the discriminator output signal according to the cancelled received signal - or its sign only - and, in the case of an insignificant difference - averaged if necessary - according to this difference - or its sign only. Compromise equalisation of the received signal may be performed prior to the crosstalk and/or echo cancellation. Controlled amplification may first be performed after crosstalk and/or echo cancellation; in this case, the adjustment parameter for the filter coefficients may be formed according to the respective amplification.

Title: Process for the biological oxidation of organic carbon compounds (BOD reduction) by nitrification and denitrification of the nitrogen compounds of effluents without external H-donors for the denitrification and plant for carrying out the process
Inventor: ELMERS PETER
IPC: C02F3/00
Filed: 1984-03-08
Abstract: The invention relates to a process for the biological oxidation of organic carbon compounds (BOD reduction) by nitrification and denitrification of the nitrogen compounds of effluents without external H-donors for the denitrification and to a plant for carrying out the process. The effluent in this case is treated in at least three separate successive purification stages. In the first stage, for the biological oxidation of organic carbon compounds, the effluent is subjected to a highly loaded activation process known per se with intermediate clarification and internal activated sludge circulation. In the second stage, the effluent is completely nitrified after passing through a bio-film reactor known per se. In the third state, in a denitrification secondary treatment tank, the effluent flows through three zones functionally separated from each other vertically arranged so that sludge is thickened and surplus sludge is withdrawn in the bottom zone, the effluent is denitrified in the central zone and sludge is separated from the effluent in the top zone. During this, part of the return sludge from the first highly-loaded activation stage, with or without thickening, with or without washing, in an intermediate stage are introduced into the central zone of the secondary treatment tank as H-donor for the denitrification with the nitrate-containing efflux water of the biofilm reactor.
