Abstract: 1282433 Display-print device MINNESOTA MINING & MFG CO 15 Oct 1969 [16 Oct 1968] 50695/69 Heading G2A The image on the screen 22 of a cathode ray tube 20 is reflected from a fixed mirror 24 through a lens assembly 50, from where it is either projected directly on to a viewing screen 70, or reflected from a mirror 30, which can be pivoted into the light path, on to a sheet of light-sensitive paper at an exposure station 84. The paper is of the heat-developable type, and passes on to a heating station 86, and then out of the apparatus. The paper is supplied from a roll 82 and the exposed length is cut off by a knife 88. The movable mirror assembly 30 is shown in more detail in Fig. 3. It comprises a beam 32 pivoted to the housing, an arm 36 pivoted to the beam and resiliently connected to it by a bolt-spring assembly 38. The mirror 34 itself is fixed to the beam 32. Movement of the mirror is controlled by a motor 40, which drives a shaft 62 carrying an arm 63 having a roller 64 at its end. The roller engages in a channel 65 in arm 36, and so pivots the assembly 30 from the full line position to the broken line position, and vice versa. When the motor is switched on to effect this movement, the cathode ray tube is automatically shut off, and is switched on again only when the mirror has become stationary either in its raised or lowered position.

The mono-chromator comprises a reflector 2, 3 for directing a plurality of beams from source 1 to a single area of grating 4, the beams being angularly spaced apart and superimposedly incident on the grating so as to form a number of similar spectrally disperse beams which are angularly spaced apart and screening means 14 having a plurality of spaced apertures each disposed to allow passage of a similar spectral portion of a respective one of the spectrally disperse beams, to illuminate a respective sample or reference position. The sample or reference fluid streams flow through cuvettes 5, 6. A detector 10, 11 may be provided for each beam or, as in Fig. 4, a single detector serves a pair of beams 15, 16 the beams being alternately interrupted by chopper 28. Fig. 4 shows a fine wave generator 56 and driver amplifier 57 for controlling the chopper motor 27 to move one step clockwise during the positive half-wave to permit beam 16 to pass and one step anti-clockwise during the negative half-wave to permit beam 15 to pass. A phase shifter 55 delays the phase of the sine wave generated by 56 by the same amount as the stepping motor 27 delays its mechanical action. The shifted sine wave gives rise to pulses at the outputs of pulse generators 53, 54 during the + and - half-waves respectively. These pulses drive solid state switches 57, 52 so that the signal wave from photo-detector 19 which has been amplified at 50, is conducted only during the plateau portions. Ratio circuitry 12 feeds read-out devices as is known.
