Abstract: ABSTRACT OF THE DISCLOSURE      An optical system having a spherical mirror is used to collect light from the surface of a turbine blade or the like which is to be contoured.  The spherical mirror is located at an equal optical distance from both the test specimen and the linear diode array so that it operates at a one-to-one magnification ratio.  The linear diode array is positioned behind the spherical mirror and it receives light focused by the mirror and reflected by a beam splitter through an opening in the center of the mirror.  None of the optical elements of the inspection system are located in the plane of movement of the test specimen so that even particularly long items such as a helicopter rotor blade can be contoured.  Identical upper and lower optical systems allow both surfaces of the test specimen to be contoured simultaneously and each system is independently operable and oriented to prevent optical interference.  An automatic gain control is provided to adjust the optical modulator so that the effective inten-sity of the spot presented to the diode array is main-tained within predetermined limits.

Abstract: INK JET HEAD Abstract of the Disclosure An inner cylindrical tube has its outer cylindrical surface spaced from an inner cylindrical surface of outer means to have an ink cavity therebetween from which ink is supplied through one or more ink jet nozzles.  At least the inner tube is a piezoelectric material so that the inner tube vibrates radially when electrically excited to produce vibrations at a desired operating frequency whereby a stream of ink droplets is supplied from each of the ink jet nozzles. The spacing between the inner surface, which has its longitudinal axis coaxial with the longitudinal axis of the inner cylindrical tube, of the outer means and the outer surface of the inner cylindrical tube is selected so that the ink cavity is resonant at the operating frequency of the inner cylindrical tube. To maintain the lowest frequencies of perturbations in the axial direction of the inner cylindrical tube substantially greater than the operating frequency, the inner cylindrical tube can be formed of a plurality of longitudinal segments acoustically isolated from each other in the axial direction.  In another form, the outer means is a body formed with a membrane providing acoustical communication from a liquid cavity between the inner tube and the body and each ink cavity, which has ink jet nozzles at its end. The liquid cavity preferably has a liquid of substantially the same density as the ink.  This enables each of the ink cavities to have a different colored ink if desired.

Abstract: ABSTRACT OF THE DISCLOSURE             Pattern cutting of sheet metal is effected auto-matically.  Conveyors move a metal sheet into a pattern cutting position, the sheet being guided exactly into position.  The sheet is clamped securely in pattern cut-ting position and a cutting tool begins cutting the pattern from the sheet.  The cutting tool is movable in x,y, and a directions so that any type of pattern may be cut thereby. The tool may comprise a scissors-like shearer, one blade being provided above the horizontal sheet being cut, and another blade being disposed below the sheet.  Supporting tips are mounted on the conveyor to support the metal sheet in cutting position while preventing damage to the conveyor during cutting. A notcher is also provided movable along each side edge of the metal sheet the notcher motors are all controlled by a computer.  After pattern cutting, the con-veyor is started up and the cut sheet transported away from the pattern cutting position, the portions cut from the sheet being supported while the waste portions of the sheet fall into a waste bin or the like.

Abstract: ABSTRACT       The invention relates to screw-coupled electrical connectors.  It is known to provide screw-coupled electrical connectors with means for providing an indi-cation of the fact that the two parts are approaching or have reached the fully mated condition and for resisting subsequent notation of the coupling sleeve in the uncoupling direction.  However, this has been accom-plished only with complex and expensive mechanisms such as movable balls mounted in a flange on the first con-nector  part and a series of holes in a flange on the coupling sleeve.  According to the invention, there is provided an improved first part of a two-part, screw-coupled electrical connector, the first part having first and second annular elements arranged coaxially with the first part and immediately axially adjacent to one another, there being defined in the first annular element a set of circumferentially spaced thrust-member-receiving regions to be engaged by thrust-members-sup-ported in a set of thrust-member-supporting regions in the second annular element, one of the annular elements being arranged to rotate relative to the first part together with the coupling sleeve and the annular element being constrained against rotation relative to the first part, means being provided resiliently to urge the thrust-members and the first annular element towards one another and to cause sequential engagement of thrust-member-receiving regions by the thrust-members when the two connector-parts approach the fully-mated condition.
