Abstract: 1,230,959. Optical deflecting-modulators. WESTERN ELECTRIC CO. Inc. 16 April, 1968 [17 April, 1967], No. 45469/70. Divided out of 1,224,331. Heading H4F. A baseband light-deflecting modulating apparatus comprises a planar reflector 71, Fig. 1, a corner reflector 72 which has an aperture at its vertex through which a laser light beam is admitted, a lens 74 disposed between the reflectors with its focal point at the surface of reflector 71, and an electro-optic crystal 75 disposed on reflector 71 and centred upon the focal point of lens 74. Two strip line electrodes 76 are attached to lateral surfaces of crystal 75 and the operation thereof is as described in Specification 1,224,331. Although this embodiment produces single-co-ordinate deflection, two-co-ordinate deflection may be effected by two such electrooptic crystal deflection stages operating in orthogonal directions having a half-wave plate therebetween (see Fig. 3 of Specification 1,224,331). The output beam is a modulated beam as well as a deflected beam in the sense that the frequency at which, and the time for which, it appears as an output, is under control of the baseband signal source 77. Instead of corner reflector 72, a lens and a backing reflector may be used as the retro-reflective device. The baseband signal applied to crystal 75 may range from zero frequency to the frequency at which the half-period is equal to the time required for the light beam to make its multiple passes between reflector 71 and 72 from entry to exit. A principal difference between the band pass (or carrier-band) deflectors of Specification 1,224,331 and the baseband deflector of Fig. 1 is that the active elements of the former deflect the beam in opposite directions alternately within each co-ordinate, whereas the active elements of the latter aways deflects the beam in the same sense in each co-ordinate. With baseband operation the deflection may be separated from the modulation of the laser beam e.g. in Fig. 2 accumulating deflection is achieved by means of tilted mirror 71<SP>1</SP>, the angle of tilt of which may be varied, whereas the modulation is achieved by means of a baseband phase modulator comprising electro-optic crystal 85. Instead of phase modulation, amplitude modulation may be effected by variable absorption or frequency modulation may be effected in a parametric device, in each case the degree of modulation being dependent on the total number of passes made by the light beam between the reflectors. Magneto-optic instead of electro-optic crystals may be utilized. Reference has been directed by the Comptroller to Specification 1,060,954.

Abstract: 1,265,542. Dictation apparatus. INTERNATIONAL BUSINESS MACHINES CORP. 29 May, 1969 [17 June, 1968], No. 27178/69. Heading H4K.  In remote dictation apparatus where the recorder is controlled by transmitted audio frequency tones, these control tones are erased from the record medium by reversing the drive and applying an erasing signal while the medium travels a predetermined distance. To enter the record mode a control tone is sent which is detected and used to set latch 41, energize recording oscillator 46 and energize motor 61 through transistors 55, 65 to drive recording medium 43. If a further control tone is now sent it will not be detected immediately and a portion will be recorded. Once the tone is recognized AND gate 73 is operated to set motor reverse latch 51 which after a delay resets record latch 41. Latch 51 causes transistors 81, 83 to conduct, thereby reversing the motor and also energizes oscillator 46 which applies an erase signal to head 45. As the motor moves in the reverse direction contact 85 is moved until it contacts a fixed contact which operates to reset the reverse latch 51 and stop the motor. In this state the recording oscillator is not operating as nothing is recorded on the recording medium. In a modification, Fig. 3 (not shown), the terminal portion of a " start recording " tone is prevented from being recorded by means of a transistor switch (101) which remains off as long as tone is being detected. This circuit also uses an electronic timing device to determine the distance through which the recording medium is reversed to erase the control tones.
