Abstract: Une alimentation de puissance a noyau de saturation (17) pour un recepteur de television comprend un reacteur saturable (SR1) ayant un noyau magnetisable (21) et un enroulement (20) situe sur celui-ci. Un courant d'excitation pour le reacteur saturable est developpe a partir d'une source (26) ayant une tension d'entree non regulee. Un flux magnetique est genere dans le noyau magnetisable qui enchaine l'enroulement du reacteur pour developper une tension de sortie a polarite alternative. Un condensateur (c) developpe un courant de circulation qui genere une force de magnetisation dans une section de noyau associee a l'enroulement du reacteur. Un aimant permanent (22) polarise le noyau (21) pour produire une seconde force de magnetisation dans la section de noyau associee. La resultante des deux forces de magnetisation developpe un flux magnetique qui sature sensiblement le materiau magnetisable de la section de noyau associee pendant chaque cycle de la tension de sortie de polarite alternative pour reguler la tension de sortie. La stabilite de la temperature de la tension de sortie sensible a la temperature est obtenue par la resistance de polarisation commandee par la temperature de l'aimant permanent (22).

Abstract: Un bloc d'alimentation (10) a haute tension pour une anode acceleratrice dans un recepteur de television comprend un transformateur a noyau saturant a auto-reglage (20) pouvant fonctionner dans une gamme considerable de temperatures sans provoquer de variations trop importantes dans la tension de l'anode acceleratrice. Le transformateur (20) comprend un noyau magnetisable (120), un enroulement primaire (20a) autour d'une section primaire de noyau (120a), et des enroulements secondaires (20a-20f) autour d'une section secondaire de noyau (120b). Une source alternative de tension d'entree (11) produit un courant dans l'enroulement primaire (20a) qui produit un flux magnetique variable dans le noyau magnetisable (120). Ce flux magnetique variable est couple aux enroulements secondaires (20a-20f) au travers du noyau magnetisable (120) afin d'induire des tensions de sortie de polarite alternee aux bornes des enroulements secondaires. La regulation de la tension de sortie des enroulements secondaires (20a-20f) est obtenue par l'utilisation d'un condensateur resonant (55 ou 550) provoquant un courant resonant dans l'enroulement (20f) de (20d) qui provoque un flux magnetique facilitant la saturation magnetique de la section de saturation (120b) du noyau (120). Le materiau de la section saturable (120b) du noyau (120) presente un ch;ingement fractionnel moins important dans la densite du flux de saturation que celui du materiau de la section de noyau non saturant (120a) dans la gamme de temperature se produisant dans la section de noyau saturant (120b) pendant le fonctionnement du bloc d'alimentation.

Abstract: Apparatus for processing information signals in a plurality of information channels comprises a comparator (634-648) for comparing samples of a first information signal in a first channel (Y) with a plurality of selected combinations of the samples of the first signal (Y). A selecting means (650) selects from among the plurality of selected combinations that combination which is the best match with the samples being compared. A generating means (706- 772) generates new samples within at least a second of the plurality of information channels (I) by use of the signal (I) in the second channel and the best match combination.

Abstract: A pair of four-pole magnet rings, each mounted for independent, concentric rotational adjustment about the neck of an in-line, tri-beam shadow-mask color kinescope, constitute a facility for introducing mutually opposing shifts of the outer beams of the in-line trio in any desired direction, without substantially affecting the central, axial beam, and without requiring internal pole piece structures for field directing purposes. A pair of 6-pole magnet rings, each mounted for independent, concentric rotational adjustment about an adjacent region of the color kinescope neck, constitute an additional facility for introducing like-direction shifts of the outer beams of the in-line trio in any desired direction, without substantially affecting the central beam, and without requiring internal pole piece structures for field directing purposes. The two magnet ring pairs together provide an arrangement for effecting static convergence of the beam trio at the kinescope screen. A third pair of two-pole magnet rings, similarly subject to rotational adjustment about the kinescope neck, provide means for introducing like-direction shifts of all three beams in any desired direction for conventional purity adjustment purposes. In a preferred application of the invention, the two-pole ring pair, six-pole ring pair and four-pole ring pair, appear in axially spaced relation of a common mount surrounding the kinescope neck to the rear of a deflection yoke (with the ring pairs in the order named, progressing from the neck base toward the yoke rear) and constitute the only neck components (exclusive of the deflection yoke) required in set-up and operation of the color kinescope.

Abstract: An electron beam influencing apparatus comprises a deflection yoke which incorporates a kinescope neck-embracing collar which extends from the rear of the yoke. The collar extends over a portion of a slidably mounted sleeve. Permanent magnet neck components are rotationally mounted to the sliding sleeve. The collar and sleeve are formed so that the yoke and collar rotates independently of the sleeve, but longitudinal movement of the yoke and collar will cause longitudinal movement of the sleeve also. A single clamp is used to secure the collar and sleeve to the tube neck. The collar may be attached to a yoke adjustment plate which allows pivotal or transverse yoke motion while maintaining stationary positioning of the adjustment plate.

Abstract: 1,242,858. Transistor amplifying circuits. RCA CORPORATION. 11 Dec., 1968 [11 Dec., 1967], No. 58805/68. Heading H3T. An amplifier circuit comprises a semiconductor device having source and drain electrodes and a plurality of gate electrodes, means for applying input signals to a first gate electrode 16 and means for applying a gain controlling potential to a second gate electrode 18. A resistor 36 is connected to the source electrode such that changes in the gain controlling potential tend to change the current through the resistor and hence the voltage between the source and the first gate electrode, and the arrangement is characterized by circuit means, i.e. resistor 30, for applying a portion of the gain controlling potential to the first gate electrode. In the embodiment the portion of the gain controlling potential applied to the first gate electrode is sufficient to keep the difference in potential between this electrode and the source electrode constant. A further fixed bias may be applied to the source electrode, by means of resistors 48, 50 to enable the use of a gain controlling potential which does not change sign over the gain control range. The arrangement is intended to maintain the voltage between the source and first gate electrode constant as the source to drain current is varied by the gain control potential.
