Patent DE-4230932-A1 (DE)
Inventor: BIRKMAYER WOLFRAM DR
IPC: H04B10/12
Filed: 1992-09-16
Abstract: An optical system superposes an optical carrier with modulation and an additional optical carrier. The system is designed in such a way that it supplies the superposed optical signal with modulation at one of its outputs and the superposed optical signal without modulation at an additionnal output. The generator is designed in such a way that it is as insensitive as possible to ambient influences. The optical signal without modulation constitutes the feedback signal for the frequency/phase control of the laser emitter. The optical signal with modulation is available for further processing, for example in a beam shaping network.

Title: Separation of dissolved matter in waste process water and sewage - using membrane separation in reverse osmosis action with precipitation of solids from the fluid phase
Inventor: HEINE WILHELM
IPC: C02F1/44
Filed: 1992-10-07
Abstract: A process to separate a solution into a fluid phase contg. dissolved matter and solids, uses reverse osmosis in an initial membrane stage. The fluid phase is mixed with a medium which mixes readily with it, and which reduces the solubility of the bivalve matter contained in the fluid so that this is precipitated as a solid. Pref. after matter has been precipitated from the fluid phase, the remaining fluid is passed to a second reverse osmosis membrane stage for the process to be repeated, or the fluid is returned to the first membrane to be mixed with the incoming fluid. USE/ADVANTAGE - The system is for treating industrial waste process water and communal sewage and the like. The operation gives an effective separation of matter from fluids, meeting ecological and economic requirements, with a higher portion of fluid contg. matter recovered from the membrane separation stage.

Title: Bonding anchor
Inventor: OETTL REINHOLD
IPC: E21D21/00
Filed: 1993-05-04
Abstract: Bonding anchor comprising an anchor rod (1) with transverse ribs (7) which is anchored in a bore by means of bonding composition. The bonding anchor is intended to be suitable for tension veins and to be retained fixedly even if there is a crack running through the bore. The bonding anchor exhibits longitudinal webs (8) which extend as far as the bore wall and subdivide the bonding composition into separate regions. Advantageously, anchor rod (1) and longitudinal webs (8) are provided with a surface coating which prevents adhesion of the bonding composition. The transverse ribs (7) may be shaped such that, in the event of tensile loading, they exert radial pressure on the bore wall. <IMAGE>

Patent DE-4321954-A1 (DE)
Title: Positive crankcase ventilation valve
Inventor: HALLBAUER HANS-JOACHIM
IPC: F01M13/04
Filed: 1993-07-01
Abstract: Known positive crankcase ventilation valves have an oil separator chamber in which the oil which has passed into the positive crankcase ventilation valve with the oil mist is separated out and is subsequently led back into the crankcase of the internal combustion engine by way of an oil return line. The disadvantage of this is that the oil return line can bend or even break off due to internal combustion engine vibrations. According to the invention this is prevented in that rings 13 provided with recesses 12 are fixed on the oil return line 7 and spring steel rods 11, which with their ends engage in the recesses 12, are clamped between the rings 13. At the same time, the length of the spring steel rods 11 is designed so that the said rods are bent so far upward that the spring steel rods bear on a connection aperture 5, which makes the connection between the positive crankcase ventilation valve 1 and the inside chamber 6 of the crankcase. <IMAGE>

Title: Process for the partial oxidation of coke furnace gas
Inventor: DIEMER PETER DR
IPC: C10J3/84
Filed: 1993-08-26
Abstract: In this process, the coke furnace gas freed of tar is precooled before the partial oxidation to at least 70 DEG C, the cooling temperature being controlled in dependence on the liquid level in the collection vessel for the wash water. At the same time, to set the optimum density of the wash water from the thick tar separator, water-containing tar is taken off in sufficient quantities until the maximum possible density of the wash water is reached. The water-containing tar taken off is fed to the partial oxidation.

Patent DE-4339419-A1 (DE)
Inventor: KELLER HELMUT
IPC: G01V3/10
Filed: 1993-11-18
Abstract: Probe for a metal detector having at least one transmitting and receiving coil (1, 2), in which two essentially oval transmitting and receiving coils are arranged alongside each other in a housing and are partly superimposed on each other on the two inner longitudinal sides (5, 6) facing each other. The longitudinal axes of the coils extend parallel to each other and the transverse axes lie on a line, the spacing (d) between the two overlapping longitudinal sides (5, 6) of the coils is selected such that the alternating induction coefficient is a minimum. A probe of such a configuration allows the detection of metal objects even with a short time constant. Furthermore, the exact determination of the point of an object is improved, since the two coils operate like two detectors working independently of each other, the receiver signals of which as a result allow both absolute measurements and differential measurements. A pulsed metal detector having a probe of such a construction and a method for detecting metal objects and the use of such a probe are also described. <IMAGE>

Title: Audio signal A=D converter
Inventor: KNOTH MATTHIAS
IPC: H03M1/18
Filed: 1994-06-14
Abstract: The analog audio signal is converted into a high resolution bit flow. The audio signal (UIn) is converted over several, parallel paths (1,2) with different amplitude sensitivity into a data flow each. Then a conversion caused faults (offset, gain error, noise) are compensated and one of both data flows is used as a bit flow for further processing. The data flow selection for further bit flow processing pref. depends on the amplitude of the audio signal. Typically each path contains three series-connected stages (21,28,66; 11-13). In both first stages (21,11) the conversion of the audio signal into a bit flow takes place, while the fault compensation is carried out in each following stage (28,66;12,13).

Title: Torque distribution control device for a vehicle
Inventor: SHIBAHATA YASUJI
IPC: F16D48/12
Filed: 1994-07-07
Abstract: In a vehicle with a torque distribution device for distributing the torque of an engine to the left-hand and right-hand driving wheels a forwards control system determines a transverse distribution torque T1 from an engine torque TE, an engine speed Ne, a vehicle speed V and a steering angle @, and a feedback control system determines a feedback control torque TF from a set yaw rate Y, which is determined from the vehicle speed V and the steering angle @, and an actual yaw rate Yaw. An output distribution torque T is determined by addition of the transverse distribution torque T1 and the feedback torque TD with a predetermined ratio, and an actuator is driven in order to distribute the engine torque to the left-hand and right-hand driving wheels on the basis of the output distribution torque T. The engine torque can thereby be suitably distributed to the left-hand and right-hand driving wheels, so that the actual yaw rate of the vehicle is brought into line with the set yaw rate in order to improve the steering characteristic. <IMAGE>
