Patent DE-3736823-A1 (DE)
Title: Process and device for separating materials
Inventor: KUHNT GUENTER DIPL ING
IPC: B07B11/04
Filed: 1987-10-30
Abstract: A process and a device for the air classification of materials are proposed. A drum classifier is used for this, the material being classified by the countercurrent air process. The material is introduced into the air current from above at the highest point of the drum. The drum itself is arranged so as to be inclined, so that the heavier material constituents are separated out at the lower end of the drum. To provide optimum separation of the materials, the effective cross-section of the drum is reduced by appropriate measures. <IMAGE>

Title: Device for regulating the DC voltage of a mains-commutated converter
Inventor: SCHWESIG GUENTER DIPL ING
IPC: H02M7/162
Filed: 1987-11-10
Abstract: An analog angle signal a, which is synchronised to a linked voltage circuit uRS, is formed by means of a phase regulator in order to address function memories in order to form digital angle function values. A DC voltage regulator supplies the required value for the amplitude of the system of alternating currents which is to be taken from the AC voltage network. By multiplying the digital angle function values by the required amplitude, digital/analog converters provide a system of required phase-current values, which system is compared with corresponding actual current values. The comparison results can either be fed into two-point regulators having a finite hysteresis width or are converted via current regulators into a system of required voltage values having no zero, which required voltage values are pulse-width-modulated by means of hysteresis-free two-point regulators and a relatively high frequency keying voltage. The output signals from the two-point regulators supply the drive signals of the valves of the converter. <IMAGE>

Patent DE-3739937-A1 (DE)
Title: Fuel pressure line
Inventor: KOSUBEK NORBERT
IPC: F02B3/06
Filed: 1987-11-25
Abstract: Fuel pressure lines for high injection pressures are made up from a pressure pipe which has the actual pressure bore and an outer pipe which surrounds the latter. Between the pressure pipe and the outer pipe, fuel leak channels are to be provided in the longitudinal direction, which fuel leak channels are formed in conventional fuel pressure lines by spacing elements which are arranged at a distance from one another between the two pipes. All the elements previously used for this, whether spring wire, plastic strips or sheet metal strips have the tendency to slip when the fuel pressure line bends, even if they are bonded to the pressure pipe. As a result, the pressure pipe does not exactly follow the bending radius of the outer pipe. Buckling points with increased risk of fracture result on the pressure pipe. The fuel pressure line according to the invention avoids the disadvantages mentioned above with the simplest possible manufacturing method. The circular segment-shaped fuel leak channels (5) are formed by flattened portions (4) on the outer surface of the pressure pipe (1).   Fuel pressure lines according to the invention are predominantly used for connecting injection pumps and injection valves to large-scale diesel engines with high-pressure injection. <IMAGE>

Title: Mounting for a cutting and embossing stylus
Inventor: REDLICH HORST
IPC: G11B3/46
Filed: 1988-03-11
Abstract: A mounting for a cutting or embossing stylus for recording an information signal onto a disc-shaped, metallic recording carrier (3) for the recording of a CD signal is specified, in which the cutting or embossing stylus (7) is arranged on a carrying lever (7), which for its part is fastened on a movably suspended articulated lever (2). The spring-mass characteristics of the carrying lever with actuator and stylus are chosen such that the system has a resonant frequency > 3 kHz and, due to a damping member (9), experiences an aperiodic damping of oscillations of the system. In this way, brief defects of the recording carrier can cause only short dropouts in the recording, which lie within the tolerances for which the CD error correction system can compensate during reproduction. <IMAGE>

Title: Method for increasing the operational reliability of bus systems used for transmitting information in communication switching systems
Inventor: BLEICHRODT MANFRED DIPL ING
IPC: H04L12/26
Filed: 1988-03-26
Abstract: In a bus system consisting of data and control lines, to which a number of access stations with their own control devices are connected in parallel, an automatic detection of faulty lines and automatic switching to stand-by is to be made possible. A test signal is sent out at predetermined time intervals whilst, at the same time, a special test word is sent on the data and control lines to be checked which are intended for the information exchange. The inverted bit pattern of this test word is transmitted with the next test signal. In the access stations, memories are provided for receiving these test words, the content of which is compared bit by bit. A line is detected to be faulty if the associated bits are identical in both memories. Switch-over to an in each case predetermined stand-by line is then effected with the aid of a switching device. This method makes it possible for operation to be maintained even when a defect occurs on a line belonging to the bus system. The operation can be maintained until the stand-by lines are used up. It is only then that a repair is absolutely necessary.

Title: Method for controlling the fuel supply in an internal combustion engine driving a vehicle
Inventor: HARDENBERG HORST DR ING
IPC: F02D41/40
Filed: 1988-04-21
Abstract: A method for controlling the fuel supply in an internal combustion engine is set forth, in which provision is made for limiting the fuel feed quantity in the higher load ranges. So that emission of pollutants is minimised but the attainment of maximum power output is still possible in the event of increased drive resistances, it is proposed that limiting of the fuel feed quantity be steplessly cancelled below a predetermined limit for the vehicle acceleration.

Title: Method and device for the determination, monitoring and adapted return of the quantities of leakage oil escaping from a hydraulic system
Inventor: KINDERMANN WOLFGANG
IPC: G01M3/02
Filed: 1988-10-06
Abstract: The present invention relates to a method which simultaneously enables the determination, monitoring and adapted return of leakage oil (3) which escapes from the components of a closed hydraulic system. For this purpose, any leakage oil (3) escaping is collected in the lower region of a housing (1) surrounding the hydraulic system and is delivered, discontinuously at a predeterminable cycle frequency, back into the tank (4) of the hydraulic system by a pump (11). A measuring device (20, 27) measures whether the pump (11) is running empty or is delivering leakage oil (3). In the event that the pump (11) is running empty, the cycle frequency is reduced to a predeterminable minimum value, otherwise the cycle frequency is raised up to a delivery (level). Depending on the cycle frequency currently present, an error message (30) or a disturbance message (31) can be triggered. A magnetically movable lifting piston (12), which can feed back leakage oil (3) from the system housing (1), via non-return valves (6, 8), into a tank (2) of the hydraulic system, is particularly suitable as the pump (11). <IMAGE>

Patent DE-3840016-A1 (DE)
Inventor: BEISEMANN GERD DR
IPC: B21D1/02
Filed: 1988-11-26
Abstract: During the straightening operation, vertical forces, inter alia, are known to occur at the straightening rolls of the straightening machine, the size of which forces depends on the properties of the material to be straightened, the dimensions of the straightening machine and the selected screw-down movements of the straightening rolls. These forces cause elastic deformation of the straightening machine, in particular of the rolls, the bearings and the frame, which adversely affect the straightening result for the material to be straightened. In order to avoid this, therefore, suitable measures must be used to keep the dependency of the straightening result in roll straightening machines free of fluctuations and deviations in the properties of the material to be straightened. This is achieved according to the invention by every straightening force which acts perpendicularly on the rotational axes of the straightening rolls and/or the roll bearings and/or on the frame of the straightening machine being measured independently and by the straightening rolls being automatically readjusted as a function of the measured values in the area of the varying pressure forces occurring.

Title: Power supply device for an X-ray CT scanner
Inventor: YAHATA MITSURU
IPC: H05G1/06
Filed: 1989-01-04
Abstract: A rectifier (13) forms a DC from the mains AC, and this DC is converted into AC voltages using invertors (14a, 14b). The AC voltages are fed to transformers (16a, 16b) and increased to an intermediate value (for example from 1 to 20 kV). The intermediate voltages are applied to voltage multipliers (20a, 20b) via a slipring (17) located between a stationary section and a rotating section of a frame (1), both of which voltage multipliers lie inside the rotating section. They change the intermediate voltages to high positive and negative voltage values (for example from +/- 60 to +/- 70 kV). The positive voltage is applied to the anode (22) and the negative voltage is applied to the cathode (23), respectively, of an X-ray tube (21). The two voltage multipliers (20a, 20b) are mutually independent units. They and the X-ray tube (21) are located in the annular housing of the rotating section in circular arrangement and with an angular separation of 120@. Between the voltage multipliers and the X-ray tube, a heat exchanger (24) for the X-ray tube (21), a voltage source (25) and a control device (26) which is supplied by the voltage source (25) are arranged, likewise at a separation of 120@. <IMAGE>

Patent DE-3918027-A1 (DE)
Title: Producing heavily filled reactive mix - filled reagent at low pressure in elastic metering chamber is injected into second reagent by its high pressure in the mixing zone
Inventor: PELZER HELMUT
IPC: B29B7/76
Filed: 1989-06-02
Abstract: A reactive mix is produced from at least two reagents which are heavily filled with mineral material, such as barytes, up to about 200-400 wt.% filler; in the process the two reagents are fed under high pressure into a mixing zone, blended together, and then discharged into a mould or other cavity. The first reagent is subjected to a low pressure of 0.5-4 bar, preferably about 1-2 bars, and, while held under this pressure, is caused to fill an elastic metering chamber; here it is held until, when the high pressure mixing zone starts to fill, that chamber is compressed reversibly by the volume to be metered into the high pressure zone; this compression is elastic and the first reagent is accordingly injected into the mixing zone. ADVANTAGE - The process, e.g. in the production of heavily filled polyurethane foam, cuts out movements between sliding surfaces in the filled component (or rotating members similarly).  The variable metering volume and the (particularly hydraulic) system to vary that volume are kept separated from each other so that no leakage can possibly occur.
