Abstract: VIDEO SIGNAL RECORDING AND/OR     REPRODUCING APPARATUS                    ABSTRACT OF THE DISCLOSURE           In apparatus for recording and/or reproducing video signals in successive parallel tracks on a record medium, and in which at least a portion of the video signals, for example, the luminance component of color video signals, is recorded as a frequency modulation on a carrier, the carrier of the frequency modulated portion of the video signals, as recorded in tracks that are next adjacent to each other, has different first and second carrier frequencies, respectively, which are in frequency interleaving relation to each other for minimizing cross-talk when reproducing the signals thus recorded.  The shifting of the carrier frequency for the frequency modulated luminance component is conveniently achieved by selectively applying different first and second bias voltages to the luminance component as supplied to a frequency modulator, with the difference between such bias voltages being effective in the modulator to establish the desired difference between the carrier frequencies.  On reproducing, the frequency modulated luminance component is demodulated, and changes in level of the demodulated luminance component corresponding to the different carrier frequencies with which the frequency modulated luminance component was recorded in next adjacent tracks, respectively, are eliminated, for example, by selectively applying suitably different bias voltages to the demodulated luminance component.

Abstract: ABSTRACT OF THE DISCLOSURE          Ventilation of rooms, particularly of relatively large rooms of irregular configuration, is improved by supplying to the room a relatively large volume flow of conditioned air having a relatively low velocity, and by deflecting such flow to desired direction by means of small jets of air introduced within the body of the flow, the volume of air supplied by the jet being considerably less than that of the flow. The velocity of the air supplied by the jet is substantially greater than that of the flow.  Accordingly, the jets impart to the main air flow or stream a momentum to distribute or direct same as desired.

Abstract: ABSTRACT OF THE DISCLOSURE           A laterally bent, impact resistant , reflective trim strip adapted to be longitudinally curved without subsequent wrinkling of the reflective material is formed to include an extrusion comprising a transparent plastic sheath encapsulating a composite metallized strip.  This metallized strip has a film of metal sandwiched between and bonded to a layer of high strength and high temperature resistant transparent plastic, such as polyethylene tere-phthalate, and a layer of opaque plastic, so that the metal film is visible through the front face of the extrusion.          The lateral shape of the extrusion provides a central portion lying in one plane and an edge portion lying in another plane so that when the extrusion is longitudinally curved, either the central portion or the edge portion will be placed in compression.  The extrusion is modified herein by an elongated compression-resistant element such as a metal stiffener, which is secured to either the rear face of the central portion or the edge portion, depending on how the extrusion will be curved, to minimize the compress-ive forces which are imposed upon any portion of the extru-sion when the same is curved.

Abstract: ABSTRACT OF THE DISCLOSURE            A control circuit for an electrical precipitator having a high voltage transformer with a bridge rectifier between the secondary of the transformer and the high voltage precipitator electrodes.  The control circuit includes a pair of oppositely poled main thyristors in the primary circuit with a firing arrangement to trigger the main thyristors to maintain desired conditions at the electrodes.  The primary circuit does not require a current limiting reactor to limit primary current when a spark discharge takes place at the electrodes.  A pair of auxiliary thyristors  are each connected in series with a capacitor.  Each capacitor and the respective auxiliary thyristor form a branch and these two branches are each connected in parallel with the main thyristors.  A rectifier is connected to keep the capacitors charged in opposing directions.  When a spark discharge at the electrodes is detected, the firing circuit temporarily interrupts the firing pulses to the main thyristor which is conducting when the spark discharge occurs, and provides firing pulses to a respective auxiliary thyristor poled to conduct in the same direction.  When the auxiliary thyristor is fired, the capacitor in series with it discharges through it and creates a voltage at the main thyristor which was conducting, and the voltage is such that the main thyristor switches to its non-conducting state before the end of the half cycle.  The high primary current that could result with spark discharge is thus stopped before it reaches destructive levels.

Abstract: ABSTRACT OF THE DISCLOSURE           Metallic articles, for instance, ferrous strips are metallized, for instance, zinc coated by passing the heated article through a coating chamber and applying thereto a continuous stream of the molten coating metal so as to uni-formly and evenly metallize said article.  Thereafter, excess molten coating metal is removed from the coated article by hot gas blasting and the hot gas blasted article leaving the coat-ing chamber is immediately  cooled.  Wiping means may be provided before applying the molten coating metal so at to deflect any molten coating metal dropping from the metallic article passing therethroughm while rollers may be arranged between the coating metal applying means and the hot gas blasting means.  Said rollers serve to remove the major part of excess coating metal from the coated metallic article and to stabilize movement of the metallic article passing through the coating  chamber.  In contrast to known application of coat-ing metal by atomizing or spraying, no gas is admixed to the continuous stream of the molten coating metal which is, so to say, gently poured onto the surface of the metallic article, Thus coating is effected within a short period of time and a non-porous coating is achieved.  Said short period of time of exposure of the steel article to the liquid zinc enables to eliminate the customary addition of aluminum to the spelter, thus permitting the use of steam for the hot blast instead of the more expensive neutral gas for that purpose, likewise eliminating the formation of White rust.
