Description
<Desc/Clms Page number 1>
Einrichtung zum gleichzeitigen Vorführen zweier kinematographischer Darstellungen auf verschiedene Teile einer Projektionsfläche mittels nur eines Kinematographen.
Gemäss der den Gegenstand der Erfindung bildenden Einrichtung zur Vorführung kinematographischer Darstellungen erfolgt die Bildprojektion mittels eines einzigen Kinematographen auf einen undurchsichtigen und gleichzeitig auf einen durchsichtigen Teil der Projektionsfläche derart, dass beide Projektionen seitenrichtig Beschauern der vorderen und rückwärtigen Seite der Projektionswand vorgeführt werden können. Dies wird durch eine besondere Anordnung von Spiegeln mit Bezug auf den z. B. seitlich des Zuschauerraumes aufzustellenden Vorführungsapparat erreicht. De Zeichnung veranschaulicht ein Ausführungsbeispiel.
A bezeichnet den seitlich vom Zuschauerraum aufgestellten Kinematograpben und a, b - zwei Spiegel, die gegenseitig und mit Bezug auf die optische Achse des Kinematographen-
Objektivs geneigt angeordnet sind. Zwischen diesen beiden Spiegeln a, b ist eine durchsichtige
Spiegelscheibe c angeordnet, so dass zwei Projektionen erfolgen ; einmal wird das Bild mittels der durchsichtigen Glasscheibe c auf den Spiegel a und das andere Mal durch die
Glasscheibe e hindurch auf den Spiegel b reflektiert. Die Projektion des Bildes von a wird
EMI1.1
derart, dass das eine Bild von Beschauern der vorderen und das andere von solchen der rückwärtigen Seite der Projektionsnäche seitenrichtig beobachtet werden kann.
Diese Einrichtung ist für alle Arten von kinematographischen Darstellungen, insbesondere auch für das in der Patentschrift Nr. 75811 beschriebene Verfahren zum Dirigieren einer Musikkapelle unter Benutzung eines die Person des Dirigenten vorfübrenden Kinematographen vorteilhaft anwendbar.
Statt einer einzigen Projektionsfläche kann man auch zwei getrennte verwenden.

Device for the simultaneous presentation of two cinematographic representations on different parts of a projection surface using only one cinematograph.
According to the device for showing cinematographic representations forming the subject of the invention, the image is projected by means of a single cinematograph onto an opaque and, at the same time, onto a transparent part of the projection surface in such a way that both projections can be shown on the right side of the front and rear of the projection screen. This is achieved by a special arrangement of mirrors with respect to the z. B. reached the side of the auditorium to be set up demonstration apparatus. The drawing illustrates an embodiment.
A denotes the cinematograph set up to the side of the auditorium and a, b - two mirrors that mutually and with reference to the optical axis of the cinematograph
Lens are inclined. Between these two mirrors a, b is a transparent one
Mirror pane c arranged so that two projections take place; once the image is through the transparent glass plate c onto the mirror a and the other time through the
Glass pane e reflected through on the mirror b. The projection of the image of a becomes
EMI1.1
in such a way that one image can be observed from the front and the other from those from the rear of the projection surface in the correct direction.
This device can advantageously be used for all types of cinematographic representations, in particular also for the method described in patent specification no. 75811 for conducting a band using a cinematograph presenting the person of the conductor.
Instead of a single projection surface, you can also use two separate ones.
** WARNING ** End of DESC field may overlap beginning of CLMS **.
