The term "bis-(aminophenyl) sulphone" includes a sulphone in which the two aminophenyl groups differ, e.g. in the position of the amino group. In (2) and (3) the metal may be Ca, Zn, Mn, Co, Cd, Cr, Ti, Ce, Zr, Th, La, Al, or alkali metal. Up to 20% mole of sulphone may be replaced by H 2 NCH 2 (CR<SP>2</SP>R<SP>3</SP>) m CH 2 NH 2 . where R<SP>2</SP> and R<SP>3</SP> are H or C #4  alkyl, and m is 0-10.

Abstract: 1302368 Recording and playback systems BATTELLE DEVELOPMENT CORP 22 Dec 1969 62361/69 Headings G4M and G5R A series of light pulses are generated by a single, fixed light source producing a beam which is deflected by a light deflection system over a photographic recording medium to record the digital information on a single track without forming an intermediate focused image between the deflection system and the recording medium, and the playback system comprises a fixed light source, a light deflection system for scanning along the track on the recording medium, and at least one fixed light detector. The system as a whole, the recording system, and the playback system are claimed separately. The system may be used for recording/playback of television or audio signals. First embodiment, Fig. 2.-A light source 46, e.g. an arc lamp or laser is energized over switch 54 and is aligned with beam splitter 50 so that its output, modulated directly or via electronic shutter 62, by the digital output of converter 24 is imaged on to a photographic record medium 22 via mirror 78. The mirror 78 is mounted on a leaf spring 80 which is attached at one end to a rotating support 84 and which carries a weight 90 at its free end. The track traced on record 22 is made spiral since mirror 78 is gradually attracted towards support 84 by steadily increasing the current supplied to coil 88. To maintain a constant bit spacing the speed of rotation of mirror 78 is also steadily increased by increasing the current supplied to clutch 74. Centrifugal action of weight 94 also assists in the movement of mirror 78 towards support 84. The current supplied to coil 88 and clutch 74 may be controlled by a motor 108. During playback from a record 22, light source 52 is energized and detector 48 is aligned with beam splitter 50 as shown. A low frequency signal is superimposed on the current supplied to coil 88, and by phase comparison at 124 with the detector output, the scanning spot is made to follow the recorded track. The wider sync. bits which separate each digital word are detected at 142 and are supplied to an integrating capacitor 138 followed by a differential amplifier 134 which controls the speed of rotation of mirror 78. Each detected sync. pulse serves to gate out a word from shift register 36 to register 150 which is followed by a digital to analogue converter 38. Second embodiment, Fig. 3 (not shown).- Scanning is effected by a rotating multi-faceted mirror, the rotational axis of which is gradually tilted so as to produce a linear raster pattern. During playback the track is scanned using a pair of detectors the outputs of which are compared to control the mirror tilting drive.
