Abstract: ABSTRACT A device is disclosed for the continuous, even coatings with a liquid coating material, of a web of material running over a counter roll, said device having an air nozzle arrangement disposed adjacent to the counter roll and rotatable about a central longitudinal axis for removing excess coating material from a web of material and for smoothing the coating.  The air nozzle arrangement has two nozzles extending over at least the width of the web of material and symmetrically offset on both sides of the central longitudinal axis by 180°, each nozzle having two nozzle lips fitted on to nozzle lip supports mounted on a housing of the air nozzle arrangement.  The convergent nozzle lip supports are adjustably mounted on the housing in the direction of the width of the nozzle slot.  In each case one nozzle lip support in the area adjacent the housing has a reduced cross-section compared to the other nozzle lip support.  The nozzle lip supports of each nozzle are interconnected by adjustably disposed tension and pressure devices distributed along the nozzle.

Abstract: ABSTRACT       A method for producing a fluid filled ring for use in a shaft sealing apparatus for attachment about a rotatable shaft for preventing leakage along the shaft, has a housing with a fixed end plate and a movable gland follower for defining a stuffing box about the shaft.  The ring is produced by providing an elastomeric tube, filling same with a chilled fluid having the property of a substantial expanding in volume on reheating.  The ends of the filled tube are closed and the fluid allowed to reach ambient temperature.  Then the ends of the tube are welded and the clamps removed whereupon the fluid fills the entire volume of the produced ring.  The advance in the art is in that no filling or vent valves are required in the process.

Abstract: Cathode-Ray Tube with Magnetic Ring Abstract of the Disclosure A cathode-ray tube 10 with a deflection system 15 and an electron gun 14 having a magnetic ring 19 attached thereto is designed so that the magnetic ring 19 is not covered by the deflection system 15. To achieve this, the magnetic ring 19 is placed further to the back of the colour-picture tube 10 than in conventional tubes, and/or the deflection system 15 is made shorter at the back. On an adjusting apparatus comprising both a magnetizing device and a deflection-system-posi-tioning device, the magnetization of the magnetic ring and the positioning of the deflection system of such a tube 10 can be performed simultaneously and independent of each other.            The measure can be taken on all tubes having a de-flection system 15 and a magnetic ring 19 for ad-justing the positions of at least two electron beams; in the case of colour-picture tubes, colour purity and static convergence are adjusted with such a ring.

Abstract: ACOUSTO-OPTICAL CHANNELIZED PROCESSOR            ABSTRACT OF THE DISCLOSURE       Coherent light is incident upon an acousto-optical cell through which bulk acoustic waves are propagating.  These acoustic waves correspond to a signal to be detected and cause periodic variations in the refractive index of the cell which interact with the coherent light.  Acoustic frequency components of the propagating waves cause the cell to diffract beams of incident co\herent light in a unique direction and to frequency shift each beam of diffracted light.  The relative phases of the acoustic frequency components are also imparted to the respective diffracted light beams.  Diffracted and undiffracted coherent light beams are recombined so that optical heterodyning takes place.  The recombined light beams are focused by a Fourier Transform lens onto a photomixer which detects the frequency difference between the diffracted and undiffracted light beams.  By detecting the recombined light beams with a photomixer array or, by deflecting the position of the undiffracted light or by amplitude or phase modulating the undiffracted light, a channelized coherent acousto-optical receiver is achieved which may function as part of a rapidly tunable bandpass filter.
