Abstract: ABSTRACT OF THE INVENTION     A method of inhibiting the occurrence of differential wall sticking in the rotary drilling of hydrocarbon wells is provided.  The yield point of the drilling fluid is measured and if necessary increased in a known manner to a minimum value computed from the weight of the drilling fluid so that solid, substantially spherical glass beads having a specific gravity between 2.4 and 2.65, a diameter between 9.84 and 187 mils, and a hardness of 5.5 Mohs placed therein will not settle, and 10 to 50 ppg of the glass beads are added to a quantity of the drilling fluid.  A slug of the glass beads/drilling fluid mixture is then spotted in the well bore adjacent a previously identified zone of possible sticking, so that a substantial number of the glass beads may be deposited in the filter cake lining the well bore adjacent the zone of possible sticking.          The presence of the glass beads inhibits the formation of a seal between a drill string, down hole tool or casing and the filter cake, which seal is necessary for the occurrence of differential wall sticking.  In an alternative method, the glass beads/drilling fluid mixture is pumped into the well bore without identifying zones of possible sticking.

Abstract: Improved Apparatus And Method For Evaporation Arc Stabilization Abstract Apparatus and method for evaporation arc stabili-zation including a target having a surface of material to be evaporated; circuitry for establishing an arc on the target surface for evaporating the target material, the arc being characterized by the presence of charged particles and a cathode spot which randomly migrates over the target surface; and a confinement ring contacting and surrounding the target surface, the ring being com-posed of a material such as boron nitride having (a) a secondary emission ratio less than one at the mean energies of the charged particles of the arc and (b) a surface energy less than that of the evaporated target material to thereby confine the cathode spot to the target surface.  Further, the secondary emission ratio of the confinement ring is preferably less than that of the target.     If the target is permeable, a permeable ring may also surround the target for effecting substantially uniform evaporation from the target.     The confinement ring may also be employed as a cover for a permeable ring to prevent migration of the cathode spot onto the permeable ring during initial clean-up of the target.

Title: Method and apparatus for the recognition of hues and  colors
Inventor: HOFFRICHTER INGO
IPC: H04N1/54
Filed: 1984-12-13
Granted: 1987-10-06
Abstract: ABSTRACT OF THE DISCLOSURE          In electronic reproduction technology, a recognition cir-cuit for hues and colors in colored surfaces is provided.  Before the actual hue recognition, the hue to be recognized is selected and its prescribed or measure color values of the RGB color space are transformed by a first color transformation into chrominance values of the chrominance/luminance color space, whereby the transformation coefficients are defined such that the transformed color locus of the hue to be recognized lies on a rotated X'Y' color coordinate system in the chrominance plane.  During the actual hue recognition, the colored surface is opto-electronically scanned and the measured color values acquired are transformed into chrominance values by a second color transformation with the transformation coefficients defined in the first color transforma-tion.  By selection of chrominance values and by quotient formation of the selected chrominance values, a hue signal which is a measure for hue deviation of the scanned hues from the hue to be recognized is generated.  After combination of the hue signal with an auxiliary control signal, a hue recognition signal is formed, this being unequal to zero when the scanned hues lie within a sector-shaped hue recognition region.  For color recognition, a color saturation signal and a luminance signal are additionally generated.  The color saturation signal and luminance signal are adjustably limited in terms of amplitude and are combined with the hue recognition signal to form a color recognition signal.

Abstract: Abstract of the Disclosure An  electrical  connector  assembly  includes an elongated, electrically conductive female terminal formed from metal wherein the female  terminal com-prises a front end shaped to receive, in electrical connection therewith, a male terminal, said front end including a plurality of walls defining a male termi-nal-receiving opening, including a first wall portion defining a first slit therein and a second wall por-tion defining a second slit therein, said slits ex-tending toward a rear end of the female terminal to provide resiliency to said wall portions for expan-sion of said opening when a male terminal is received in said male terminal-receiving opening. The first slit extends a greater distance toward the rear end than the second slit so that the first wall portion has a greater resiliency than the second wall portion.  The female terminal includes opposed wall portions each having one or more lateral inward projections extend-inq within  the male  terminal receiving  opening  for electrical  connection  to  the  male  terminal.    The lateral projections extend inwardly to a greater ex-tent at a location nearer the first  slit than at a location nearer the second slit to compensate for the greater  resiliency  in  the  first  wall  portion  to achieve  substantially  uniform  electrical  contact pressure at symmetrical contact area portions of op-posed projections.  The rear end of said female termi-nal  is adapted for electrical connection to another circuit element and an  intermediate portion of the female terminal electrically connects the front end to the rear end.  The male terminal includes a front end cooperatively shaped to fit within the male ter-minal-receiving  opening  of  the  female  terminal  and has opposed walls shaped for relatively high pressure electrical contact against the lateral projections of said female terminal.
