Abstract: 1418919 Infra-red scanner TEXAS INSTRUMENTS Inc 11 Dec 1972 [17 Dec 1971] 57078/72 Heading H4F Infra-red optical scanner comprising an array of detectors (e.g. diodes) attached to a rotatable member to thereby scan a scene, the resulting video signal from each detector being fed to a corresponding light emitter (e.g. diode) in an array thereof which is also attached to the rotatable member, wherein the array of detectors is periodically exposed to infra-red radiation from a reference temperature source (e.g. once per rotational of the array) whose temperature is equal to the average temperature of the scene to thereby produce control signals for the video signals upon which clamping circuits may operate to effect D.C. restoration. The output signals of all the diodes in the array (e.g. a linear array) are averaged during the time when the scene is being scanned and during the time when the temperature reference source is being viewed, and by comparing these two measurements the temperature of the reference source is adjusted until they are equal. The array of detectors is periodically exposed to the temperature reference, e.g. a heat sink, by means of a chopper comprising a mirror attached to gear which is coupled to the rotating portion of the scanner. A television camera is focused on the light emitter array to thereby produce a composite video signal. The scanner also includes a lens system incorporating an automatic focusing mechanism, and gain and emphasis control circuits for the video signals.

Abstract: 1280839 Superconductor coils COMMISSARIAT A L'ENERGIE ATOMIQUE 22 Dec 1969 [27 Dec 1968 (2)] 62316/69 Headings H1K and H1P A superconducting coil energized by a voltage generator has a current rectifier, mounted within the cryogenic environment, connected across its terminals and poled so that when the generator voltage is of such polarity that the current flows through the coil in the desired direction the rectifier is reverse biased. In a first embodiment, Fig. 2, a semi-conductor diode D is connected across the coil L within the cryogenic environment E. When the generator G is of the desired polarity the diode D is reverse biased and the coil charges but when the voltage drops to zero or reverses in polarity the diode D is forward biased and conducts allowing the coil current to circulate through it resulting in a slow decay due to the diode forward voltage drop. In a second embodiment, Fig. 3 (not shown), a full wave rectifier is inserted between the generator and the coil shunted by the diode so that the voltage applied to the coil is of constant sign and this arrangement can be used with an A.C. generator. The diode shunting the coil provides the return path for the stored current when the generator voltage drops to zero. In a further embodiment, Fig. 7 (not shown), the generator comprises a superconductor transformer the output of which is rectified by a series diode and applied to the coil which is shunted by a second rectifier. In a modification, Fig. 8 (not shown), the transformer winding is centre tapped and a pair of diodes are used to provide full wave rectification. The rectifier may also comprise a transistor with its base connected to its collector either directly, Fig. 5 (not shown), or via a parallel circuit of a resistor and a capacitor, Fig. 6 (not shown), or may be a thyristor with its gate connected to its anode via a resistor.
