2 Claims. (Cl. 250-166) This invention relates to improvements in mulincludes all of the electrodes and it may be vactiple light sensitive tubes and has for an object, uumized, gas-filled or filled with liquid, dependthe provision of a light sensitive tube having ing upon the type of light sensitive tube desired.

An cathodes with a single rectangular beam of light anode 29 is common to all of the cathodes and and to interrupt the light passing to one or more is provided with a terminal 38. An exciting lamp cathodes by means of recordings on a record 3| is provided with a reflector 32. A condensing .3 passed between the light source and the cathodes. lens is positioned adjacent to the exciting Other objects of the invention will become aplamp 3i and projects the rays of light in the form parent to those skilled in the art upon a perusal of a rectangular beam. The rectangular beam of the specification and the appended claims. is further defined by means of a slit 34 formed This application is a continuation in part of in the mask plate 35. The rectangular beam, application Serial Number 436,264, filed March after leaving the plate 35, passes through the 20 17, 1930, now Patent No. 1,998,461 issued April record E9 and the recordings in the sound tracks 23, 1935, for Method and apparatus for recording 35 effect the light falling upon the cathode 2i, and reproducing sound. the recordings in the sound track 3'! effect the Referring to the drawings: light falling upon the cathode 22, and so on.

Referring to Figure l, a method of moving the Such a tube is shown in Figure 4, including record ifiis shown wherein the record passes over 50 a plurality of cathodes, three of which are desa plurality of rollers 65, 66, 61, and 68. ignated by the numerals it it and i2. These Having the apparatus connected as shown in cathodes are suitably insulated from each other. Figures 1 and 2, so that the record passes across An anode is common to all of the cathodes, desor cuts the light beam, the closing of the contacts 5 ignated by the numeral 13. A suitable case 14 of any one of the interrupter arms, for example,
the arm 42, connects the cathode 2 l, with which it is associated, to the amplifier 4i and a tone will be reproduced by the loud speaker H3 in accordance with the interruptions of the light beam by the sounding track 36 in the record l9. Other tones will be reproduced from the other sound tracks when the oth r interrupters are closed. If all of the interrupter arms close simultaneously, a tone, which is a composite of all of the recordings, will be reproduced by the loud speaker l0.
It is obvious that instead of the use of the interrupters for controlling the circuits between the cathodes and the amplifier, hand operated keys may be used thereby enabling an operator to play a tune.
It is likewise obvious that although the record is shown as a photographic record, perforations or slits in paper or cardboard sheets or strips may constitute a record.
Figure 3 is a modification in which an exciting lamp is designated by the numeral H. A condensing lens ?2 is positioned adjacent to the exciting lamp and a plate 13 is provided with a rectangular slit The record, in this case, is in the form of a disc 75, recordings thereon being designated by the numerals 75, '11 and 18. This record is provided with a hub 19 and may be secured to a suitable shaft 83 by means of a nut 8!. A multiple light sensitive tube 32 is provided having a common anode, the terminal of which is designated by the numeral 83, and a plurality of cathode terminals, two of which are designated by the numerals 84 and 85. The record 15 is normally positioned between the slit l4 .and the tube 82.
The new and improved multiple light sensitive tube makes it possible to reproduce recordings which have been recorded close together, thereby making it possible to construct very compact apparatus for reproducing the recordings.
Although the arrangement and operation of a simple embodiment of the invention is herein shown and described, it is obvious that many changes may be made in the form and structure shown without departing from the spirit of the invention as defined in the appended claims.
What is claimed is:
l. A multiple light sensitive tube comprising an evacuated envelope having a wall portion divided into separate insulated cathode element sections, a separate connection for each cathode mounted in the wall portion adjacent thereto, and an anode element coextensive in length with said cathode sections and mounted in the envelope to one side of the cathode sections.
2. A multiple light sensitive tube having an evacuated envelope, a plurality of cathode element sections located adjacent to and conforming with one wall surface of the envelope, said cathode sections being insulated from each other and coextensive with the adjacent wall section supporting the same, and an anode bar element located in the envelope in spaced relation to all of the cathode wall sections.
