Patent DE-3705803-A1 (DE)
Title: Backwash filter
Inventor: FRIEDRICHS DIETER
IPC: B01D29/48
Filed: 1987-02-24
Abstract: The backwash filter has a filter chamber (10) into which is inserted a cylindrical filter insert (2) through which flows a medium to be filtered from the inside towards the outside. The filter insert has an internal cage (20), the cylindrical wall of which is provided with essentially horizontally extending slot-like windows (24), which are separated from each other by bridges and in the interior of which is arranged an axially movable pusher (3) which removes the filter residues. The pusher (3) has on the periphery an annular gap opening (30), which is connected to a sludge discharge (15), which, on a stroke movement of the pusher (3), successively covers the windows (24) of the internal cage (20), as a result of which the filter medium, during the filter operation, is partially washed free from the outside towards the inside as a result of a pressure difference between the filter outlet side and the sludge discharge side. This backwash filter, retaining a simple operationally reliable construction, is intended to be further developed in such a way that during the backwash on the filtrate side, only a small pressure drop occurs, but nevertheless a reliable washing of the active filter surface occurs. The slot-like, essentially horizontally extending windows (24) of the internal cage (21) are arranged along a helical line. The horizontal gap opening of the pusher only partly covers the windows running at an angle thereto, and this... Original abstract incomplete. <IMAGE>

Title: Pedal for bicycle
Inventor: WENDE HANS
IPC: B62M3/08
Filed: 1987-03-16
Abstract: For the purpose of transmitting the forces of the foot with as uniform a pressure as possible on the ball of the foot, the tread surface of the pedal is constructed to be concave and to be inclined with respect to the foot in horizontal projection, as is the ball of the foot. For the purpose of positive-locking connection to a correspondingly profiled shoe sole, the tread surface is provided with holes and recesses of equal size and spacing. Constrictions and widenings are also arranged in the holes, into which undercut studs of the profiled shoe sole can engage, so that limited pulling forces are also transmitted. The tread surface is located only on one side. A counterweight, which is elastically fastened to the other side and also has a light-reflecting surface, holds the pedal vertical when the latter is not loaded. The fastening of the pedal axle in the crank is cylindrical without a thread, and the mounting of the pedal on the pedal axle comprises a cylindrical roller bearing in the centre of the pedal, which also takes over the axial guiding, and a cylindrical sliding bearing.

Title: Modulator for generating an audio-frequency-modulated single side band signal with suppressed carrier
Inventor: LOGEMANN JOERG DIPL ING
IPC: H03C1/60
Filed: 1987-05-14
Abstract: To generate this signal, an unmodulated RF signal is applied to the reference signal connection of a D/A converter with resistance network. At the zero crossing of the audio-frequency modulation signal, the phase of the RF signal is switched over by 180@. From the audio-frequency modulation signal, digital control values are derived for the D/A converter which, as a result, operates as controllable RF attenuator. At the output of the D/A converter, a DSB signal is available from which the required side band can be obtained by means of a filter.

Title: Commercial vehicle with a diesel engine and an exhaust emission control system
Inventor: THUMM HERMANN DR
IPC: F01N13/08
Filed: 1987-10-05
Abstract: In commercial vehicles which are driven by a diesel engine, it is often difficult to accommodate an exhaust emission control system serving to control the engine exhaust gases without loss of payload space, since the exhaust emission control systems for the treatment of high power diesel engines sometimes have very large overall dimensions. According to the invention, the solution to this problem lies in fitting the exhaust emission control system (1) on the vehicle roof. At the same time it is proposed that, if wind deflectors are used on the driver's cab of the vehicle, the exhaust emission control system (1) be provided in the space below the wind deflector. The exhaust emission control system (1) may, in particular, be connected to the wind deflector in such a way that wind deflector and exhaust emission control system (1) can form a separately mountable assembly component. <IMAGE>

Title: Switch having rapid release and the capability for positive opening of the contacts, especially for movement limiting devices
Inventor: TADDEO UGO
IPC: H01H3/00
Filed: 1987-11-27
Abstract: In the case of switches which are used for movement limiting devices there is a risk that the contacts of the switch will separate in an inadequate manner. The safety of the movement limiter is thus reduced. In order that a switch having rapid release and the capability for positive opening of the contacts, as can be used especially for movement limiting devices, operates with a high safety level, the switch has a stationary contact (7), at least one moving contact (13), a quick-release mechanism (34, 31, 23, 39, 19), a positive-opening mechanism (5, 13) and an operating lever (4). The operating lever (4) acts directly on the positive-opening mechanism (5, 13) and indirectly on the quick-release mechanism. <IMAGE>
Patent DE-3740791-A1 (DE)
Title: Pipeline system
Inventor: BLOEDEL-PAWLIK JUERGEN
IPC: F01N13/08
Filed: 1987-12-02
Abstract: In order, in the case of exhaust-gas systems which are enclosed by insulation shells for reducing the heat radiation, to avoid the rattling which occurs after a relatively short period of time as a result of the ends of the insulation shells widening, the invention proposes to introduce either a prestressed wire-mesh ring or an expandable mat in the end regions of the insulation shells. Consequently, the widened ends are reliably held at a distance from the exhaust-gas line, with the result that the rattling of the insulation shell on the exhaust-gas pipe is reliably prevented.

Title: Process and apparatus for decreasing the pollutant content of waste water
Inventor: DOELCHOW ULRICH DIPL ING
IPC: C02F3/10
Filed: 1988-02-19
Abstract: The invention relates to a process for decreasing the pollutant content of waste water (effluent) which has already been pretreated. In order to specify a process and an apparatus for carrying it out by which the pollutant content of phosphorus compounds and nitrogen compounds and organic substances of a previously pretreated waste water can be decreased in a simple manner to values which permit problem-free discharge into municipal sewage treatment plants, it is proposed that the waste water proceeds through a multiplicity of purification stages in each of which it is applied from the top, distributed over a large surface, onto a packing formed of biomass, perculates between the packing particles by the action of gravity and drains off at the bottom in order to enter, if required, into the next purification stage, that to achieve an aerobic fermentation, an airstream is conducted through the packing of each purification stage from bottom to top, that a sump is formed downstream of the last purification stage, in which sump solids settle as sludge, that the purified waste water is conducted away above the sludge zone and that the biomass, after its extensive fermentation, is cyclically exchanged for fresh biomass. <IMAGE>

Title: Drive device for an ink ribbon in a typewriter or office machine of similar design
Inventor: RESKE THOMAS
IPC: B41J33/34
Filed: 1988-10-07
Abstract: Drive devices for an ink ribbon are already known, in which the letters and characters are struck overlapping one another on the ink ribbon in multistrike operation and are struck in a non-overlapping manner on the ink ribbon in single strike operation. For this purpose, a drive motor is provided, for example, by means of which different pulse signals are fed to the stepping motor for advancing the ink ribbon. The invention is based on the object of providing an ink-ribbon drive for printers, which is simple and cost-effective and has a low ink-ribbon consumption. This object is achieved in that the slide (1) can be driven via a first motor (16) and the tensioning means (30) can be driven separately via a second motor (54). In this case, during the movement of the slide (1) by the first motor (6) and by the second motor (54) which can be switched in, a different relative speed can be realised between the ink ribbon (5) and the recording medium. Owing to the toothed belt drive which can be switched in, a relative speed occurs between the recording medium and the ink ribbon (5) and thus a reduced ink-ribbon consumption occurs. <IMAGE>

Title: Method and arrangement for controlling the drive force and/or braking force of the drive motors of a running axle-less tractor unit at the frictional engagement limit of the wheels
Inventor: HAHN KARL DIPL ING
IPC: B60L3/10
Filed: 1988-11-04
Abstract: In the said method and arrangement, the boundary of the unstable slip area is to be determined and the wheel set or the group of wheel sets is to be then returned into the stable slip area by reducing the drive or braking force again beyond the minimum frictional engagement. In order to achieve in all operating states a variation in the wheel slip which oscillates as closely as possible about the maximum frictional engagement, it is proposed that the time of termination of the reduction of the drive force or braking force should be detected with reference to the traction force or braking force which is dropping again and is transmitted to the rails, the force which is actually effective on the rail being determined from the drive force or braking force or the torque of the drive motor and the measured wheel set acceleration (or deceleration) according to the relation FZ = FEngine-mwheelset.awheelset FB = FEngine+mwheelset.awheelset and in that the first derivation over time of the drive force or braking force is used for the signal resolution for stopping reduction. <IMAGE>
