Abstract: A method for verifying the authenticity of a document utilizes artifacts of the printing process. The method includes optically capturing at a predetermined magnification a first image of an indicia printed on the authentic document. A corresponding indicia on a document to be authenticated is optically captured at a predetermined magnification. The captured images and the printing process artifacts depicted therein are characterized. Authenticity is verified where the characterization indicates the captured images are sufficiently identical. An indication is issued as to whether the document is authentic.

Abstract: Prior to sorting, the amount of data in each record of a collection of records is normalized to a value chosen from a designated set of values. The designated set of values selected from a progression of numbers computed as an integer power of two. The normalized collection is partitioned into a plurality of sub-sets of records to be sorted in parallel. Sorted sub-sets of records are merged to arrange the records in a predetermined order.

Abstract: A polyphenol compound wherein the aromatic rings are linked by direct bonds or by a divalent link in the ortho position relative to the --OH group and the end aromatic rings contain either oximino substituents or substituted alkylaminomethyl substituents in the ortho position. The compound can be coated onto a metal surface to give improved corrosion resistance. The metal surface can be zinc-coated steel or zinc phosphated steel. The polyphenol compound can be the only coating material or can be incorporated into a surface coating composition such as a paint.

Abstract: A system for retracting the drive spindle of a power tool includes a drive shaft which has a spline portion and a threaded portion. During normal operation, the drive spindle is rotated by interconnection of a drive gear with the splined portion of the drive spindle. When it is desired to retract the drive spindle, a drive spindle feed gear is locked into position and the threaded engagement of the drive spindle feed gear and the drive spindle causes the drive spindle to retract.

Abstract: A composition comprising at least one compound which is a 2,6-bis hydroxyalkylamino methyl phenol. The composition is typically water-based and certain of the compounds are novel. The composition or the compound may be deposited onto a metal surface. The coated metal surface can have corrosion inhibiting and/or adhesion promoting characteristics.

Abstract: An indexing coupling for a drill includes a hollow inner race, a hollow outer race, and a sleeve member. The hollow inner race and hollow outer race are affixed to one another by a plurality of ball members which are positioned by a plurality of detents in the hollow inner race. The balls also extend into holes in the hollow outer race. When the balls are positioned within the holes in the hollow outer race and within the detents in the hollow inner race by the sleeve member, the hollow inner race and the hollow outer race are rigidly connected one with respect to the other. When the sleeve member is moved the ball members become disengaged from the hollow inner race thus allowing indexing of the outer race with respect to the hollow inner race. This indexing of the hollow outer race with respect to the hollow inner race allows selective rotatable indexing of the drill housing with respect to the nose piece.

Abstract: A fused ring compound having hydroxy, carboxylic acid and hydroxyalkyl substituent groups and the metal salts or complexes thereof. The hydroxyalkyl group is especially a hydroxymethyl group. The compound is prepared by reaction of the hydroxy carboxylic acid derivative with formaldehyde in an alkaline medium at a temperature of not more than 50.degree. C. The compounds, especially the metal salts or complexes thereof, can be used to provide corrosion inhibition of metals, for example iron.

Abstract: A compound contains a ligand group and at least one group of the general formula --XR.sub.n where X is a linking group which contains at least one hetero-atom, R is a saturated hydrocarbyl group containing at least six carbon atoms or is an unsaturated hydrocarbyl group containing at least three carbon atoms. The ligand group can be a polyhydroxyhydrocarbyl, a triazole, an imidazole, an indazole, a thiazole, an oxazole, a carbamate, an xanthate or a phthalazine. The compounds can be used to improve bonding between a metal and a coating material in contact with the metal surface. The metal may be a tire cord and the coating material rubber or a rubber composition.

Abstract: A tetraoximino derivative of a bisphenol, for example the 3,5,3.sup.1,5.sup.1 -tetraoximino methyl derivative of 2,2-bis(4-hydroxyphenyl) propane, can be coated onto a metal surface to give improved corrosion resistance. The metal surface can be zinc coated steel or zinc phosphated steel. The tetraoximino derivative can be the only coating material or can be incorporated into a surface coating composition such as paint.

Abstract: A compound containing a ligand group and a group of the general formula --NRCOR.sup.1.sub.a X.sub.b CR.sup.2 .dbd.CHCOR.sup.3 is used for treatment of a metal. The ligand group can be a triazole, an imidazole, an indazole, a thiazole, an oxazole, a carbamate, an xanthate or a phthalazine, or derivatives thereof. The compounds can be coated onto a metal surface, for example a copper surface. The metal surface may also be coated, simultaneously or subsequently, with a surface coating composition such as a paint or lacquer or an adhesive. When used with an adhesive, an increase in the adhesive strength is achieved.

Abstract: An automatic shift drill for rotationally driving a bit into a laminated workpiece at one of two speeds according to the depth of the bit in the workpiece is disclosed. A cam block element has flag sections and gap sections corresponding to the various layers of the workpiece. The cam block element is mounted on a spindle of the drill to move in translation with the bit. A vent element has an orifice which is adapted to be closed when it is adjacent to one of the flag sections and open when it is adjacent to one of the gap sections. Shifting means responsive to pneumatic pressurization changes the rotational speed of the bit from one speed to the other speed. The orifice vents the shifting means when it is adjacent to a gap section to drive the bit at the appropriate speed through the corresponding layer and seals the shifting means when it is adjacent to a flag section to drive the bit at the other speed appropriate for the layer corresponding to the flag section.

Abstract: A limp material handling system includes a manipulating apparatus for selectively manipulating one or more layers of limp material on a support table. Folding is accomplished by lifting a curvilinear region of the material, reshaping that lifted region as desired, and lowering that lifted region to a curvilinear region on the support table. A seamed article assembly system incorporates the manipulating apparatus, a seam joining apparatus and a multiple parallel endless belt system for tactile presentation of the limp material to the seam joining apparatus. An optical sensing system provides information representative of the position of the limp material being handled. A programmable computer, or controller, coordinates and controls the operation of the manipulating apparatus, seam joining apparatus, belt assembly, and optical sensing system to provide automatic assembly of seamed articles.

Abstract: A machine tool system having an adjustable implement mounted in a holder or chuck and moveably positioned relative to a moveable workpiece support, wherein implement adjustments are produced by controlled differential motion between the implement holder and an adjustment fixture on the workpiece support. The support is moved to engage the implement in the fixture, from which state further relative movement unlocks an implement clamp and produces a desired adjustment in the implement. Typical implement adjustment applications would include setting of a boring bar cutting radius (or setting of a measurement gauge dimension). The adjustments can be performed open loop based on prior calibration of implement adjustment versus extent of support motion, or closed loop wherein an initial cut (or measurement) is made by open loop implement adjustment with subsequent adjustments based upon a measurement made of the implements effective cutting (or measurement) dimension.

Abstract: A method for improving the sensitometric response of a persistently conductive photoreceptor is disclosed.
