Title: Windscreen for motor vehicles
Inventor: HUBER GUNTRAM DIPL ING
IPC: B60S1/04
Filed: 1981-08-17
Abstract: In the case of wipers of motor vehicles which in their position of rest lie countersunk on an area of the windscreen lying underneath the rear edge of a front bonnet, there is in particular the risk that the wiper blades become frozen to the window as a result of snow or the like which has found its way in, and that they thus become inoperative. In order to remedy this, an arrangement is proposed in which a planar heat exchanger which is connected to the coolant circuit of an internal combustion engine of the vehicle is arranged on the inside of the windscreen, which heat exchanger can preferably be controlled in an infinitely adjustable fashion by a thermovalve which is controlled as a function of the external temperature.

Title: Winding apparatus for strips, in particular for winding magnet cores
Inventor: GERLACH JOACHIM VON
IPC: B65H23/18
Filed: 1981-08-31
Abstract: When winding up magnetic material to form so-called magnet cores, it is necessary to ensure uniform magnetic properties of the cores to make the winding operation reproducible. Optimum magnetic and mechanical characteristics require that the strip tension is continuously reduced as the winding operation progresses. To achieve this, the strip (1) is passed over a tension roller (10), braked by a braking motor (17), to the winding mandrel (12), coupled to a drive motor (18). The drive motor has a pulse generator (20) as revolution counter, which continuously reduces the armature current of the braking motor (17), and consequently the braking torque, by means of a computer (31). This winding apparatus is suitable in particular for winding rectangular magnet cores. <IMAGE>

Title: Method for automatically controlling the reactivity of a developer fluid for use in a developer device, and device for carrying out the method
Inventor: MIZUTA MASAJI
IPC: G05D21/02
Filed: 1981-12-10
Abstract: A speed detector for area blackening detects a rate of area blackening of a developed film and outputs an analog signal to a voltage/frequency converter which converts it into a digital signal. The digital signal is conducted to a dividing-type counter which divides it with respect to frequency and outputs an additional signal to an up and down counter. The up and down counter is incremented by the additional signal and outputs a high-level signal via a gate to a timer. The timer is operated by the high-level signal in order to operate a valve so that an additional developer fluid is supplied to a developer tank. The gate is closed by using the output signal of the timer during its operation. The up and down counter is decremented by the high-level signal which has been passed through the gate.

Title: Colour recording method and device for carrying out the method
Inventor: BLUME ROBERT DR
IPC: B41J2/065
Filed: 1982-03-27
Abstract: In a colour recording method in which the application of colour droplets produced in a droplet former on the surface of the recording medium is controlled imagewise by means of a control electrode, the use of complicated colorant nozzles which are prone to faults is avoided in that the droplets are drawn off by means of electrostatic forces from the tips of a capillary wave field produced on the surface of a paint container (1a) filled with electrically conductive paint. The amplitude of the oscillation production is selected such that the release of drops can be brought about by the use of relatively small electrostatic supplementary forces. Preferably a plurality of rows of pin electrodes (9) which are arranged on the rear of the recording medium (7) serve as control electrodes, said electrodes being controlled by means of the pulses of an optical image sensor of conventional type. A metal layer (26) which is applied on the surface of a piezoelectric vibrator device (20) arranged in the fluid container (1b) and is connected to earth potential can serve as the counter electrode. <IMAGE>
