Title: Method and device for selectively determining the future shaft axis of rotors taking account of their mass distribution
Inventor: HACK HEINRICH K
IPC: G01M1/02
Filed: 1981-03-09
Abstract: Whereas modern balancing machines, which are provided for balancing in two balancing planes, are set and calibrated (assignment TS/mmg unbalance) by attaching known masses at a prescribed radius in the balancing planes, which are likewise known, it has so far not been possible to address the balancing planes in the case of balance centring machines. Although it has been possible to carry out a "separation of the planes" after mutual displacement, calibration (unbalance/adjustment path) has not been possible. It has been a movement to zero. So far, only the displacement of the rotor has been measured at its ends, and an assignment has been undertaken on this basis. The calibration has taken no account of the tilt. In order to operate balancing and centring with the measuring means of normal balancing machines and to facilitate selective adjustment (balancing), provision is made of a balancing plane, assigned to the adjustment plane, for the rotor to be adjusted. This balancing plane is termed the X0-plane, being given along the lines of Fig. 1 in accordance with the relationship X0 = J0/m.s. If a balancing weight is attached in the calculated X0-plane, it is displayed or taken into account only in the assigned measuring device. It is therefore possible to proceed in a manner corresponding to the general manipulation when balancing. The introduction of the X0-planes in accordance with the "balancing planes" makes it possible to assign the adjustment path in a definite way as geometrical variable and unbalanced display. As a result:   1) Since the values are available immediately and in final form, the time consuming regulating process previously customary can be replaced by a control process.   2) The values can be stored and used at any desired time. 3) The possibility that the adjustment path is larger than the material requirement (remaining raw) can be monitored. 4) It is possible to carry out measurement and handling in two separate stations. 5) Subsequent unbalances, dependent first and foremost on the adjustment path, can be forecast and therefore taken into account. In addition to other indications, in order to carry out the said method a device is proposed by means of which the balance centring machine can be set up to carry out the abovementioned method by means of few manipulations. <IMAGE>

Title: Plug-in connection for a shield-shaped coking plate
Inventor: STOG WILHELM ING GRAD
IPC: C10B25/06
Filed: 1981-06-11
Abstract: Coking oven doors are to seal off the actual coking oven as tightly as possible from the atmosphere. To protect the coking oven door, in order to extract evenly and completely the gases being liberated, in particular in the region of the coking oven door and in order to carbonise evenly the head of the coke cake, on the interior of the coke oven doors a coking plate composed of overlapping shields is arranged. This coking plate or the individual shields are held by distance pieces which retain by their base piece the insulating layer protecting the door body. The distance pieces have connection bolts set at right angles, which correspond with the bore holes provided in the transverse bridges of the T-shaped reinforcing ribs. The distance pieces are formed from two pieces of angle iron which are arranged on the base pieces at right angles to each other at a distance. The lowest distance piece is designed in the form of a sliding shoe which facilitates the insertion of the coking oven door into the oven opening. The levelling rod guide and the top shield form a unit which is joined to the door body via a mounting frame. Such a coking oven door is easy to assemble and has the necessary freedom of movement to absorb thermal expansion and contraction and other changes in length.   <IMAGE>

Title: Winding for electrical machines
Inventor: KALLAS HANS DIPL ING
IPC: H02K15/12
Filed: 1981-08-26
Abstract: The invention relates to a method for coating coil and winding parts of electrical machines and equipment with a layer of liquid plastics which, owing to a particular polymerisation method, consist of reactive polysiloxanes (e.g. according to DE-A-2405828). In order to coat the surface of coils in the winding overhang uniformly and thus to achieve an effectively insulating separating layer between live parts of different phase and to increase the tracking resistance, the winding wrapped with spacers is dipped for at least 10 sec into a dipping composition. Prior to this, those parts of the winding and the motor stator which come into contact with the dipping composition are coated or sprayed with suitable adhesion promoters. After the dipping process is finished, said parts receive a mechanically hard coating which is produced by the cross-linking caused by the humidity of the air and which has excellent electrical properties.

Title: Mixing valve device for hot and cold water in a low-pressure water system
Inventor: HOPPE HELMUT
IPC: F16K11/20
Filed: 1981-10-15
Abstract: A mixing valve device for hot and cold water in a low-pressure water system is intended to be constructed such that the mixture ratio and the flow rate can be controlled simply, in a finely sensing manner. In addition, on operation of the mixing valve device, it is intended to be possible to operate a switch directly, i.e. not by the pressure in the water system, in order to switch a pump on or off. To this end, the mixing valve device essentially has mixing slide valves and shut-off slide valves which can be displaced in two holes and can be moved in a linear manner by in each case one slide-valve knob connected to them. A hot water duct and a cold water duct, which open into the hole of the mixing slide valve, are covered alternately depending on the position of the mixing slide valve. The shut-off slide valve moves an O-ring into a sealing cone and hence determines the flow rate of the mixed water. An operating element of a switch can be arranged in the movement path of the shut-off slide valve.

Title: Device for generating and evaluating modulated axle load measuring bridge signals in railway systems
Inventor: SCHMIDT EBERHARD DIPL ING
IPC: B61L1/00
Filed: 1982-01-29
Abstract: The invention serves for determining axle loads of rolling goods wagons. The signals of a measuring bridge circuit (1/4) are converted into frequency-analog signals and evaluated with the aid of a digital circuit (6, 9, 13). This digital circuit is composed, inter alia, of a differential counter (9) with a forwards counting input (+m) and a backwards counting input (-m). For correct evaluation, these two counting inputs must be fed, independently of the travel direction, with switching signals with increasing positive difference between the extreme values of the measurement signal characteristic. In order to achieve this, a switch-over device (10) is provided preferably composed of commercially available, logically connected switching elements constructed using digital technology. In each case, a rail contact (K1, K2) is attached to the track in the region in front of and behind the measuring bridge circuit (1/4), the said contacts indirectly controlling the switch-over device (10). <IMAGE>

Title: Regulating device for influencing the engine power of a motor vehicle
Inventor: HOERNIG RUDOLF DR ING
IPC: B60T8/175
Filed: 1982-07-10
Abstract: What is provided is a regulating device for influencing the engine power of a motor vehicle equipped with an anti-slip control device, which regulating device ensures a power-reducing adjustment of the power-regulating member, for example the throttle flap, if appropriate necessary within a control cycle of the anti-slip control device. To give the driver readily noticed and unmistakeable feedback on such a power-reducing action, there is provided as an actuator of this regulating device a hydraulic cylinder, of which the piston, by valve-controlled loading with the high outlet pressure of the auxiliary-pressure source of the anti-slip control device, executes its stroke causing the power-reducing adjustment of the power-regulating member, this piston preferably being arranged so as to engage directly on the accelerator pedal, so that power-reducing adjusting movements take place counter to the foot force exerted by the driver. In a preferred embodiment of the regulating device, the control signals for a control valve, by means of which the pressure build-up and pressure reduction in the hydraulic cylinder are controlled, have superposed on them brief control pulses which are communicated to the driver during the control phases of the anti-slip control device as pulsating movements of the accelerator pedal and which thereby emphatically signal to him that the anti-slip control device is actuated and that the vehicle is in a critical region of driving stability.
Patent DE-3230404-A1 (DE)
Inventor: BLAU HEINRICH
IPC: H02H11/00
Filed: 1982-08-16
Abstract: An arrangement for generating in each switching panel of a multipanel switching facility of an electrical power distribution network a digital operating-state image derived from command inputs and switching position signals. The digital operating state image is transmitted to a collecting memory arranged in a coupling panel which produces an overall image of all switching panels; which overall image is transmitted to the individual switching panels at periodic time intervals. A checking procedure is then conducted in the individual switching panels using the overall image. The arrangement utilizes microprocessors which are coupled to one another so as to exchange data via several transmission paths which are one-bit wide. This arrangement obviates the need for an interlock cable harness in the switching panels and cross-cabling between the switching panels.

Title: Fuel injection system for mixture-compressing, multi-cylinder internal combustion engines
Inventor: UNGER JOSEF
IPC: F02M26/36
Filed: 1982-08-20
Abstract: The invention relates to a fuel injection system for mixture-compressing, multi-cylinder internal combustion engines with separate intake pipe lines each providing a continuous feed into one cylinder, which lines branch off from an intake manifold, in which an air flow sensor plate, deflectable by the combustion air flow, and at least one arbitrarily controllable throttle valve are arranged and the air flow sensor plate adjusts a control piston of a metering unit, comprising differential pressure valves and arranged in the fuel line, for the proportional metering of fuel, the fuel being fed to injection valves by way of lines. In order to simplify the injection system and to obtain an improved mixture preparation, especially when the internal combustion engine is idling, the metering unit is provided with only one differential pressure valve and meters a quantity of fuel corresponding to all cylinders, which quantity of fuel is fed to only one single injection nozzle, the injection nozzle being arranged in a distributor, from which one line per cylinder branches off into the respective separate intake pipe lines downstream of the throttle valve, and the distributor being connected by way of an air line to the intake manifold upstream of the throttle valve but downstream of the air flow sensor plate.

Title: Eroding voltage analyser for a spark-erosion machine
Inventor: PETERICH FRANK-NORBERT DIPL IN
IPC: B23H1/02
Filed: 1982-08-26
Abstract: An eroding voltage analyser is described which detects and evaluates the high-frequency voltage changes on the electrode in a spark-erosion machine. Operational amplifiers (8, 9, 10), which are connected in parallel as voltage comparators and evaluate the effective voltage pulses which exceed a set burning voltage and short-circuit voltage pulses which are less than the burning voltage, are driven by the erosion voltage, reduced via a voltage divider (6). The signals of the operational amplifiers are converted via a pulse-conditioning stage (13) and a signal-conditioning stage (14) into analog voltages whose magnitude is indicated via light-emitting diode chains (18, 19, 20). The indicated time relationship between the effective voltage pulses and short-circuit voltage pulses permits optimum setting of the eroding process of the spark-erosion machine. <IMAGE>

Title: Process for surface-hardening of workpieces and equipment for carrying out the process
Inventor: OVERKOTT FRANZ JOSEF
IPC: C21D9/32
Filed: 1982-09-16
Abstract: In a process for surface-hardening of workpieces and equipment for carrying out the process, the workpiece surface to be hardened is first heated to the hardening temperature and then cooled to a temperature below the martensite point by means of a quenching agent of relatively weak action. To produce a hardening result which is as free of cracks as possible, and the most uniform state of strain possible after hardening, and thus to minimise the delay in hardening, the workpiece is treated, once it is below the martensite point, with a coolant acting more vigorously than the quenching agent, to adjust the temperature distribution of the initial state.
