Description

Filtereinrichtung an Bildwerfern zur farbigen Wiedergabe von Schwarz-Weiß-Filrnen Zusatz zum Patent: 660 415 Die Erfindung hat eine Weiterausgestaltung der Filtereinrichtung an Bildwerfern zur farbigen Wiedergabe von Schwarz-Weiß-Filmen nach dem Hauptpatent zum Gegenstand und besteht darin, daß zusätzlich in den Strahlengang einschaltbare Filter vorgesehen sind, die erheblich kleiner als der Obj@ektivdürchm,esser sind.Filter device on image projectors for colored reproduction of black-and-white films Addition to patent: 660 415 The subject of the invention is a further development of the filter device on image projectors for colored reproduction of black-and-white films according to the main patent and consists in that additionally in the beam path Switchable filters are provided which are considerably smaller than the lens diameter.

Es hat sich nämlich ergeben, daß sich mit der Anordnung nach dem Hauptpatent, bei der sowohl vor dem Objektiv als auch zwischen Objektiv und Bildstreifen verstellbare Farbfilter oder Farbfiltervorrichtungen vorgesehen sind, von denen mindestens .die zwischen Objektiv und Bildstreifen anzuordnenden Filter je aus mehreren verschieden gefärbten Teilen bestehen, peng umgrenzte Momenteffekte nicht erzielen lassen. Diesem Mangel hilft die hier vorgeschlagene zusätzliche Filtereinrichtung ab. Für jede be#lebige Fläche des Bildes läßt sich das eine ,oder andere Miniäturfilter tnschalfen, wodurch das Gesamtbild belebt und die Wirkung erhöht wird, Bohne daß die Hauptfiltereinrichtung verstellt oder verändert zu werden braucht. Die Filter können in der Nähe des Objektivs vorgesehen sein und sind so anzuordnen, daß sie sich leicht in den Strahlengang einschalten und auch wieder aus dem Strahlengang entfernen lassen.It has been found that with the arrangement according to the main patent, with the adjustable both in front of the lens and between the lens and the image strip Color filters or color filter devices are provided, of which at least .die Filters to be arranged between the lens and the image strip each consist of several different filters colored parts, do not allow limited moment effects to be achieved. This one Deficiency is remedied by the additional filter device proposed here. For every one or the other miniature filter can be applied to the active area of the image, whereby the overall picture is enlivened and the effect is increased, without the main filter device needs to be adjusted or changed. The filters can be placed near the lens be provided and are to be arranged so that they can easily be in the beam path switch on and have it removed from the beam path again.

Die kleinen Miniaturfilter sind z. B. an dünnen Stäbchen mittels Fäden befestigt und können innerhalb eines teilweise offenen Gehäuses gelagert sein, wie das dargestellte Ausführungsbeispiel näher ersehen läßt. Es zeigen: Fig, i das Zusatzgerät in Ansieht von der Kabinenwand her gesehen, Fig.2 das an der Kabinenwand befestigte Zusatzgerät im Längsschnitt und Fig.3 eine Aufsicht auf das an der geschnittenen Kabinenwand befestigte Zusatzgerät.The small miniature filters are z. B. on thin rods by means of threads attached and can be stored within a partially open housing, such as the illustrated embodiment can be seen in more detail. It shows: Fig, i the additional device viewed from the cabin wall, Fig.2 is attached to the cabin wall Additional device in longitudinal section and Fig. 3 a plan view of the section on the Cabin wall mounted accessory.

In einem Behälter i sind an den oberhalb des Behälters angebrachten Stangen 2 die Filter 3 mittels der mit verschiedenen Bügeln versehenen Halter 5 an den sehr dünnen Fäden 6 aufgehängt, und zwar so, daß die an den Haltern 5 befestigten Filter 3 quer zur optischen Achse auf den Stangen 2 verschiebbar sind. Die Halter 5 können mittels der Bü,ge1 q. in verschiedenen Höhenlagen aufgehängt werden. Die Filter, die nicht benötigt werden, können somit seitlich aus der Lichtfläche 7, die in Fig. i schraffiert dargestellt ist, herausgeschoben werden,oder mittels der Halter 5 sa hoch aufgehängt werden, daß sie nicht in die Lichtfläche 7 hineinragen. Das Gehäuse i ist an der Kabinenwand B mittels der Konsole 9 vor der Lichtöffnung i o befestigt. .In a container i are attached to the above the container Rods 2 the filters 3 by means of the holders 5 provided with different brackets suspended on the very thin threads 6 in such a way that they are attached to the holders 5 Filters 3 are displaceable on the rods 2 transversely to the optical axis. The keepers 5 can be done using the Bü, ge1 q. be hung at different altitudes. the Filters that are not required can thus be removed from the side of the light surface 7, which is shown hatched in Fig. i, are pushed out, or by means of the Holders 5 are suspended high so that they do not protrude into the light surface 7. The housing i is on the cabin wall B by means of the console 9 in front of the light opening i o attached. .
