Abstract: An apparatus (11) for inspecting the sealing surface (86) of a container (15) for dips, saddles and lean is disclosed. While the container (15) is rotated, a beam (77) of light is projected horizon­tally above and through a finish portion of said container. An optical detector (100) detects the height of said sealing surface (86) by detecting the location of a minimum in the light beam. Dips in the height indicate dips or saddles. Alternatively, an opaque bearing member (204) is lowered onto the sealing surface in the path of the light beam to provide a reference indicative of the prevailing height of the sealing surface. Light passing between the underside of the bearing member and the sealing surface indicates a dip or saddle.

Abstract: A method is provided for the preparation of stable aqueous dispersions of non-solvated, un-neutralized, low amine, low acid number polymerized fatty acid polyamide resins. Molten resin is blended with a predetermined amount of water at a temperature above the melting point of the polyamide resin in the presence of a cationic surfactant which is the salt of the amine of the formula:
      wherein R represents an alkyl having 16-20 carbon atoms and n₁ and n₂ are the same or different and each represents a whole number from 1-3 and n₃ is 0 or 1, is included in the mixture. The resulting mixture is then subjected to sufficient comminuting forces to form an emulsion in which droplets of the polyamide resin have a volume average size distribution of about 20 microns or less in diameter and preferably 5 microns or less. The resulting emulsion is then cooled to a temperature below the melting point of the polyamide resin causing the emulsified droplets of the polyamide resin to solidify as finely divided particles to form stable aqueous dispersions, which are especially useful for hot melted adhesive applications, when utilized in coatings, inks, and the like.

Abstract: A diode (D₁) is coupled to a low voltage end terminal (150a) of a tertiary high voltage winding (W₃) of a horizontal flyback transformer (T1). The diode (D₁) is back biased during trace and during a portion of the second half of retrace by a voltage (145V) that is coupled to the diode (D₁) through a resistor (R₂) from a B+ voltage source. When the diode (D₁) is back biased, the resistor (R₂) dampens parasitic ringing current in the tertiary winding (W₃) caused by the leakage inductance of the transformer (T1). During a portion of retrace, occuring prior to the time the diode (D₁) is back biased, the diode (D₁) is conductive and bypasses the resistor (R₂). This prevents the resistor (R₂) from increasing the output impedance at the ultor terminal.

Abstract: Thin strips (15a) of ferrite are inlaid into the surface of a read-after-write magnetic head (10) between the read (13) and write (12) gaps for reducing feedthrough. The ferrite shields extend across a substantial portion of the tape-engaging surface between the read and write gaps. Further reduction of feedthrough is achieved by inlaying additional shielding (15b) outboard of the read gaps (13). The shielding does not encircle individual read or write gaps, but may extend across tracks in a multitrack head. The ferrite shielding absorbs magnetic flux which otherwise strays from the magnetic cores. Material and manufacturing costs are maintained low because the shields are small and simple in geometry.

Abstract: An electric coil (20) induces a magnetic flux through a magnetic flow path (22, 24) which terminates in pole faces (26, 28) disposed parallel to a gap (30) therebetween. A non-ferrous pivot element (36) is mounted to one of the pole faces adjacent an edge thereof most distant from the gap. An armature (40) which is at least partially ferromagnetic is held in firm frictional engagement with the pivot element by a taut band (42). The armature pivots about the pivot element in accordance with current flowing through the coil. A fluid nozzle (54) is mounted adjacent the armature such that fluid flow through the nozzle is throttled in accordance with pivotal movement of the armature, hence, the electrical control signal current in the coil.

Abstract: To improve the quality of welds, the invention, in a method for welding by means of alternating current in which the actual effective welding current is measured during one cycle and regulates the phase displacement of the application of the current flow during the next cycle of the alternating voltage, proposes that deviations of the actual effective welding current during all welding cycles performed from a desired effective current be taken into account during the welding cycles only being performed. A welding device for welding by means of alternating current with two welding electrodes, a power supply for these electrodes and a means of controlling the effective welding current during each cycle of the alternating voltage has a computer (7) for taking into account deviations of the actual effective welding current during preceding welding cycles of a welding operation from a desired effective welding current flow during the further welding cycles to be carried out during the respective welding operation. …<IMAGE>…

Abstract: The present invention provides a cleaning method for use in a color electrophotographic apparatus in which color toner images formed by using a plurality of color toners on a photosensitive medium by repeating charging, exposure and reversal developing steps are transferred to a paper at one stroke. 
     The toners include color toners and a black toner. Each of the color toners is a toner for DC electric field jump developing method which serves to develop without making contact with the photosensitive medium. The black toner is a toner for two-component magnetic brush developer which is mixed with a carrier to be used. The two-component magnetic brush developer is used both as a developer serving to develop in contact with the photosensitive medium and a cleaning agent serving to clean the toners remaining on the photosensitive medium after transfer operation. 
     Further, the color toners and black toner are charged, when mixed with the two-component magnetic brush developer, to have a polarity the same as the polarity thereof at the time of developing.

Abstract: A master oscillator power amplifier (MOPA) system which isolates the master oscillator (MO) from the return amplified beam by dividing the return beam into two components, introducing a phase shift between the components, and recombining the phase shifted beam components through constructive interference into an output beam directed away from the MO. A destructive interference return output is directed back towards the MO, but is held to a negligible level by making the phase shift approximately equal to an odd number of half-wavelengths at the return beam wave-length. In the preferred embodiment a stimulated Brillouin scattering phase conjugate mirror (PCM) is used to direct the amplified beam for a second amplification pass, while a Mach-Zender interferometer transmits the beam both before and after double amplification. The original beam is replicated after its first path through the interferometer by having the interferometer phase shift also equal an integral number of half-wavelengths at the input beam wavelength, prior to frequency shifting by the PCM.
