absorbieren. Aus der Zeichnung ist zu ersehen, dass der Schirm D im wesentlichen keinen Einfluss auf den vom Signal entlang der Geraden 10 ausgesendeten Hauptsignalstrahl hat, dass aber im wesentlichen das ganze Licht, welches von einer ausserhalb gelegenen Quelle auf das Signal beispielsweise entlang der Geraden 11 auffällt, irgendeinen Teil des Schirmes D trifft und hier ohne vom Signal reflektiert zu werden, absorbiert wird. Es werden somit unerwünschte oder sogar Gefahr bringende Täuschungssignale, die durch die Reflexion vom St eu1icht VCi anlasst wel den, im wesentlichen ausgeschlossen sein.
PATENT-ANSPRÜCHE :
1. Lichtsignalvorrichtung mit einer im Inneren befindlichen Lichtquelle und optischen Projektionsmitteln, die aus zwei voneinander distanzierten Linsen bestehen, gekenzeichnet durch eine derart zwischen die Linsen geschaltete Vorrichtung, dass das von einer äusseren Lichtquelle kommende Licht davon absorbiert wird, während der Durchgang der von der inneren Lichtquelle ausgesendeten Strahlen nicht unterbrochen wird, zum Zwecke um die Reflexion von Streulicht und die dadurch hervorgerufenen Täuschungssignale zu vermeiden.

absorb. It can be seen from the drawing that the screen D has essentially no influence on the main signal beam emitted by the signal along the straight line 10, but that essentially all of the light which is incident on the signal from an external source, for example along the straight line 11 , hits any part of the screen D and is absorbed here without being reflected by the signal. Undesired or even dangerous deceptive signals, which are caused by the reflection from the interfering VCi, are thus essentially excluded.
PATENT CLAIMS:
1. Light signal device with a light source located inside and optical projection means, which consist of two spaced apart lenses, marked by a device connected between the lenses that the light coming from an outer light source is absorbed by it, while the light from the inner one passes through Light source emitted rays is not interrupted, for the purpose of avoiding the reflection of scattered light and the resulting false signals.
