Title: Operational amplifier with a wide bandwidth
Inventor: ABELE HERMANN DIPL PHYS
IPC: H03F3/45
Filed: 1988-08-27
Abstract: For an operational amplifier with a wide bandwidth and having a small offset voltage, low noise, wide-band common-mode suppression and high insensitivity to supply-voltage fluctuations, it is proposed that the inputs of at least two differential amplifiers of different bandwidths and no-load gain are connected in parallel and are to be connected to the input terminals of the operational amplifier. The outputs of the differential amplifiers are connected to a current amplifier, the low-impedance output of which is used as the output of the wide-band differential amplifier and from which a feedback is connected to the input of the differential amplifiers.

Title: Process for treating paint mist wash water
Inventor: GREINER DETLEF DR
IPC: C02F3/12
Filed: 1988-09-21
Abstract: A process is specified for treating wash water, of the paint mist produced in painting, arising in the spray-painting of motor vehicle bodies. In this wash water, e.g. subsequently collected in sedimentation tanks, a previously inexplicable sudden increase in vicosity occasionally occurs. This viscosity increase which has occurred and the resulting slime formation is reversed by adding phosphates to the wash water. Orthophosphates, diphosphates and polyphosphates have proved to be suitable for this purpose.
Patent DE-3832630-A1 (DE)
Title: Method and apparatus for plasma-arc cutting in a water bath
Inventor: MADSEN HANS DIPL ING
IPC: H05H1/34
Filed: 1988-09-26
Abstract: The protection of the plasma jet from the adverse effect of the water is achieved by a hyperbolic gas swirl which rotates at high speed around the plasma jet and thus produces such centrifugal forces that they prevent the admission of water to the plasma jet. The gas swirl is produced with a plasma-arc cutting torch, on the nozzle cap of which five to twenty gas-conducting guides of appropriate inclination are symmetrically arranged. Gas-conducting passages are formed by an attachable torch housing with a screwed-on torch cap. Gas is then admitted to the gas-conducting passages. The construction of the attachable torch housing enables workpieces to be worked in normal atmosphere and under water.
Patent DE-3840312-A1 (DE)
Title: Force-limiting means
IPC: F16L55/10
Filed: 1988-11-30
Abstract: The force-limiting means essentially comprises two pipes (1, 2) which are plugged one into the other, can be drawn apart by a specific length and then come into mutual abutment with stops (4, 7; 8, 10). The stops form at least one predetermined breaking point, with the result that, after a predetermined force has been exceeded, the pipes can be released from one another. The inner pipe (2) bears a disc-shaped sealing body (10) which, when the pipes are drawn apart, moves into a radial seat (12) of the outer pipe and closes the latter. <IMAGE>

Title: Method for determining the water quantity in the washing container of a washing machine
Inventor: STAMMINGER RAINER DIPL PHYS DR
IPC: G01F23/14
Filed: 1989-01-12
Abstract: The economical electronic analog pressure measuring devices used for determining water levels generate output signals subject to tolerances, which must first be corrected for the precise driving of the inlet magnetic valve. Likewise, the actual deviations of the magnetic valve must be corrected with reference to flow velocities. A known device does not take this into account, that is to say expensive precision sensors and magnetic valves are necessary. In the method according to the invention, cheap analog pressure measuring devices, which are corrected, are used. In the method according to the invention, the output signals (Ua) generated by increasing pressure between two washing machine levels are measured, recorded and stored at exact time intervals. On the basis of a desired curve, which corresponds to an ideal analog pressure measuring device and the known appliance geometry, the output signals (Uaact) are matched to adequate output signals (Uades). By means of the accurate recording with time of the levels and of the water contents known herefrom, the influence quantities of the magnetic valve are also eliminated. The method according to the invention is suitable for application in programme-controlled washing machines and dishwashers. <IMAGE>

IPC: F16K31/02
Filed: 1989-03-08
Abstract: A valve arrangement for the simultaneous opening and closing of two separated supply pipes for liquid media having different characteristics, especially a different pressure. In each of the supply pipes (Z1, Z2) there is arranged a valve, which is operated by its own medium, is controlled by a magnetic armature (6a/b) and has a differential piston (2a/b), carrying the valve plate, on whose one side there is arranged a pressure chamber (3a/b) which is connected to the valve inlet flow, is connected via a valve seat (4a/b) to the valve outlet and on whose other side there is arranged a control chamber (5a/b) which is connected via a discharge hole (2.1a/b), which is arranged centrally in the differential piston (2a/b) and can be closed by a magnetic armature seal (6.1a/b) arranged on the magnetic armature (6a/b), to the valve outlet and via a control hole (2.2a/b), arranged eccentrically in the differential piston, to the pressure chamber (3a/b). The two valves are driven via a common magnet system (St). Said magnetic system has a magnetic coil (7) in whose coil axis there is arranged a guide tube (8a/b) in which the two magnetic armatures (6a, 6b) are guided such that they can move. When the common magnet system (St) is energised, the two magnetic armatures (6a/b) pull in simultaneously and the two valves open. <IMAGE>

Title: Circuit arrangement for a solenoid (electromagnetic) valve
Inventor: HOFFMANN GERHARD
IPC: H01F7/18
Filed: 1989-04-04
Abstract: Circuit arrangement for a solenoid valve. An electromagnetically actuated valve of a hydraulic system is connected to a supply voltage via a power switching element. In the off state, the valve adopts a first position and a second position in the on state. In order to sustain the second position, the full supply voltage is applied, which leads to a correspondingly high current and thus to heating of the excitation (field) coil. In order to reduce the power demand after carrying out the switching process, provision is made to switch the supply voltage on to the excitation coil in a pulsed manner, so that the average power demand of the coil is reduced. The power reduction leads to less heating; the correspondingly smaller force is sufficient to hold the control element (actuator) in its switching position. General electromagnetic control elements.

Title: Drum-speed control process for domestic washing machines and device for carrying out the process
Inventor: STAMMINGER RAINER DIPL PHYS DR
IPC: D06F33/40
Filed: 1989-04-06
Abstract: Before spinning, the laundry articles must already be distributed as evenly as possible in the rotating drum. In known appliances, this takes place during a single smooth start with a subsequent constant reduction speed. The process according to the invention distributes and loosens the laundry articles in a plurality of smooth starts at different reduction speeds. An optimum laundry distribution with a minimum unbalance is thereby achieved. The reduction speeds are selected so that laundry articles located within half to three-quarters of the laundry-drum diameter are loosened again and are distributed more and more evenly in a plurality of successive smooth starts. The reduction speeds are increased further and further from smooth start to smooth start and their rate of speed rise ( DELTA n1,2,3)/ DELTA t is decreased more and more to a constant final smooth-start speed. The drum-speed control process is suitable for domestic washing machines with electronic speed regulation. <IMAGE>

Abstract: The pneumatic brake device for rail vehicles has disc brakes (8,10,12 and 9,11,13) and block brakes (19,20) acting on the same vehicle wheels (4,5). In order to avoid damage to the treads (25) of the vehicle tyres (4,5) which can occur as a result of the block brake (19,20) being actuated at low driving speeds or when the vehicle is stationary, switching valves (30,31) are inserted into the brake pressure lines (18,28,29) to the application cylinders (21,22) of the block brake (19,20), which valves release the block brake (19,20) or at least reduce its application force when a low travel speed is undershot and when the vehicle is stationary. The actuation of the disc brakes (8,10,12 and 9,11,13) takes place without being influenced by the switching valves (30,31). <IMAGE>
