Description

Betr.: Feuchtigkeitsabhängiges Schaltgerät -insbesondere zur Verwendun£r. in Fahrzeugen Bei Kraftfahrzeugen sind zur Scheibenwischersteuerung meist Ein-Aus-Schalter oder Intervall-Schalter vorhallclen. Intervall-Schalter haben jedoch den großen Nachteil, daí; sie bei wechselnden Vcrhältnissen einer stetigen Nachstellung der Wischergeschwindigkeit bediirfen. Nachstehendes Gerät arbeitet dagegen völlig vollautomatisch nach Einschalten der Zündung und übernimmt die Aufgaben der Wischersteuerung ohne Zutun des Fahrers, der sich somit völlig dem Straßenverkehr zuwenden kann. Für Heckscheibenheizungen sind noch keine entsprechenden automatischen Steuerungen vorbanden, es bedarf Ein- und Ausschaltvorgänge durch den Fahrer.Re: humidity-dependent switching device - especially for use. in vehicles In motor vehicles, there are usually on / off switches for controlling windshield wipers or reverberate interval switch. However, interval switches have the big one Disadvantage, daí; with changing conditions a constant readjustment of the Require wiper speed. The device below, on the other hand, works fully automatically after switching on the ignition and takes over the tasks of wiper control without Contribution of the driver, who can thus completely turn to the road traffic. For rear window heaters there are no corresponding automatic controls in place, it is necessary to and switch-off processes by the driver.

Beschreibung: Zwei auf einer Klebefolie in einem bestimmten Abstand angebrachte metalische Leite in Kombination mit einem Transistor oder Thyristor-Verstärker (Abb. 1) dessen Empfindlichkeit so ausgelegt ist, daß beim Beschlagen, Beuieseln, beim Redgnen oder beim feuchten Beschmutzen der Klebefolie der Übergangsweiderstand an den metallischen Leitern fällt, die Basis des Eingangstransistors erregt wird und ein Transistor durchschaltet. Bei @leineren Strömen kann der oder die Transistorstufen direkt schalten, bei größeren Strömen wird über ein Relais gesteuert.Description: Two on an adhesive film at a certain distance attached metallic conductor in combination with a transistor or thyristor amplifier (Fig. 1) whose sensitivity is designed in such a way that when misting, pouring, the transition resistance when redgneing or when the adhesive film is dampened falls on the metallic conductors, the base of the input transistor is excited and a transistor turns on. With lower currents, the transistor stage (s) switch directly, with larger currents it is controlled via a relay.

1) Beispiel KFZ - Abb. 2 Wird diese Klebefolie I z.B. an die Windschutzscheibe eines KFZ so angebracht, daß daß Folienstück I mit den offen liegenden Leiten von den Scheibenwischern über strichen wird, so schaltet der Transistor und somit der Scheibenwischer immer dann, wenn Regen, Nieselregen oder auch nur Beschlagen oder Beschnutzen der Scheibe und somit des Folienstijekes eintritt. Nach überstreichen durch den Scheibenwischer wird die Klebefolie I und die Scheibe gereinigt, und wenn keine nene Beregung eintritt, der @ransistor gesprerrt, was ein Ausschalten des Wischermotors zur Folge hat. Ein manuelles Ein- bzw. Ausschalten des Scheibenwischers entfält somit.1) Example of a car - Fig. 2 If this adhesive film I is attached to the windshield, for example of a motor vehicle so that the piece of film I with the exposed conductors of the windshield wipers is swept over, the transistor switches and thus the Windshield wipers whenever it is raining, drizzling or even just misting or Soiling of the window and thus of the Folienstijekes occurs. After painting over the windscreen wiper cleans the adhesive film I and the windshield, and if so no rain occurs, the @transistor is blocked, which means that the Wiper motor has the consequence. Switching the windshield wiper on and off manually thus unfolds.

2) Beim Beschlagen an der Innenseite der Frontscheibe kann ein derartiges Gerät auch großen Mutzen haben, weil bei verringertem Abstand der metallische Leiter auf der Floie der Transistor bereits beim Ansteigen der Luftfenchtigkeit und somit vor einem Beschlagen der Scheiben das Heizungsgebläse bzw. eine Scheibenheizung einschaltet und ein Beschlagen vor seinem Entstehen verhindert.2) If the inside of the windshield is misted, this can happen Device also have large hoods, because the metallic conductor is smaller when the distance is reduced on the floie the transistor already when the air tightness rises and thus Before the windows mist up, the heater fan or a window heater switches on and prevents fogging from occurring.

3) Nach Abbeizen der Fenchtigkeit schaltet das entsprechende Aggregat wieder ab, weil nach Trocknen der Scheibe bzw.3) After the paint has been stripped off, the corresponding unit switches again, because after the windshield or

des Leiterstückes I der Übergangswiderstand an denmetallische@ Leitern des Folienstückes I steigt und somit der @ingangstransistor gesperrt wird.of conductor section I is the contact resistance on the metallic @ conductors of the foil piece I rises and thus the input transistor is blocked.
