Title: Measuring imbalance in loaded drum - during spinning of washing machine, by measuring relative imbalance and then inertia of drum
Inventor: HENNEMANN MICHAEL DIPL ING
IPC: D06F34/16
Filed: 1990-11-30
Abstract: A process for measuring imbalance in a loaded drum during the spinning process of a washing machine and features a number of steps. During the slow start-up, the actual revolution speed is measured several times per revolution of the drum. The value of the measured actual revolution speed is compared to that of the previously measured revolution speed. The sum total of the amts. of the differences between the values is worked out and represents a measure for the relative imbalance. When the termination condition for the start-up phase has been reached, at a first point in time, the control of the washing machine motor is interrupted. If the drum reaches a pre-set slowing down speed at a second point in time, the control of the washing machine motor is resumed. In order to determine a measure for the inertia of the loaded drum by means of the microprocessor, two things are registered: a factor specific to every motor/drum system and the difference between the first point in time, at which the setting value for controlling the washing machine motor has reached a pre-set value. A measure for the absolute particular imbalance is worked out using the measure for the inertia of the loaded drum an dthe measured for its relative imbalance. ADVANTAGE - The process respresents a simple method for measuring the particular imbalance for every individual spinning process.

Title: Biological waste water cleansing basin - has guides to impose a vertical component on the horizontal flow path
IPC: C02F3/32
Filed: 1990-12-19
Abstract: Assembly to clean waste water biologically, in sealed basins contg. water or marsh plants is claimed where the water flow is along the plant root level, in a generally horizontal flow component from one side to the other. Lateral guides in the basin, across the flow line, impose a vertical component into the waste water flow path. Pref. the guides are located alternately in the upper and lower zones of the basin, or they are placed only in the lower or upper zone. The guides in the lower zone of the basin are of a bonded base and the remaining basin filling is of a non-bonded base. The guides are of material which can be worked with a flat surface such as wood, plastics, metal, concrete, brickwork, flat waste material and the like. The guides have openings to allow part of the water flow to pass through. The guides are placed vertically within the basin, or they are at an angle of up to 45 deg. against the vertical. Guides at the upper zone of the basin extend by 50-200mm above the filling. The guides can be used as temporary supports for sleepers, grids and the like as walkways. The upper guides are suspended from carriers, aligned on the longitudinal direction of the basin and parallel to the water flow line, so that the guides and the longitudinal carriers form a carrier grid. ADVANTAGE - The assembly gives a single cleansing basin, where the water is exposed to the max. cleaning action, without the hydraulic effect of following the line of least resistance through the system.

Filed: 1991-02-02
Abstract: The bearing for hinged car interior fittings and for sun visors in particular, has a shaft with one end attached to the car body so as to turn at the other end which is inserted into a bearing on the car interior. The product also has a spring-loaded locking device which engages the interior fitting and shaft in at least one position of latter and which needs a force to move it in its range of adjustments. The locking device has two locking features coaxial with the shaft and located axially adjacent to each other these features have locking elements and one of the features is fixed so that it cannot be turned; the other can be turned relative to the shaft but is fixed to the car interior fitting; the spring is pre-loaded so as to act along the axis of the shaft and it presses the two locking devices together, at least one of which can be moved longitidinally relative to the shaft. The car interior fitting is preferably made of polypropylene. ADVANTAGE - Allows sun visors which are much thinner than has been possible. If it is desired to re-use the interior fitting concerned the shaft can be withdrawn from it as the locking device plus shaft form one integral unit. The shaft is simply inserted into the fitting for use and can therefore be readily checked and, if found faulty, removed again. The assembly can be packed as one compact item. The bearing is not affected by temp.
