Abstract: A method and apparatus for vertically scoring a tamper-indicating plastic closure includes a rotatably-driven carousel which includes mandrel assemblies at the periphery thereof. Each mandrel assembly includes a rotatable mandrel on which a respective closure is positioned in operative association, so that the mandrel and closure are moved relative to an associated scoring mechanism. The scoring mechanism includes at least one, and preferably a plurality, of rotatably driven scoring blades, with each blade arranged to engage and cut the pilfer band of a respective closure. Significantly, the system can be operated so as to closely approximate the preferred radial movement of the blade with respect to the closure, thus minimizing "digging" of the scoring blade into the plastic of the closure.

Abstract: A disposable comedone extractor for use in dermatologic surgery fabricated of a synthetic resin reinforced with natural or synthetic fibers. It has been found that the use of a reinforced synthetic resin ensures that the extractor of the present invention is fully disposable, and thus far less expensive to manufacture and use, as compared to conventional extractors fabricated from metals. In addition, the use of a synthetic resin allows greater control of the flexibility of the extractor as compared to rigid metal extractors.

The shank has a ringed portion with annular grooves defining annular rings having a uniform, outer diameter, helical grooves intersecting the annular grooves, a cylindrical land having a smaller diameter and dividing the ringed portion into an axially longer subportion nearer to the tip and an axially shorter subportion nearer the head, a cylindrical land between the tip and the ringed portion, and a cylindrical land between the head and the ringed portion. The fastener is driven through the board and through the framing member wall so that the head bears against the board, so that the tip and the shank form, from the wall of the framing member, a generally annular lip projecting toward the tip and so that the lip is disposed around the cylindrical land dividing the ringed portion.

Abstract: After a metallic insert has been used precisely to define a cavity for a microelectronic chip in a laminated, multi-sheet, predominantly ceramic substrate having metallic features, any green sheet and metal-polymer composite paste residues are removed from the metallic insert by immersing the metallic insert in an ultrasonically agitated bath containing a first solvent having a relatively high boiling point for about five to fifteen minutes, replacing the first solvent with a second solvent having a relatively low boiling point, and drying the metallic insert in hot air or hot nitrogen to remove the second solvent. Preferably, the first solvent is an alkoxy alcohol, such as 1-methoxy-2-propanol or 3-methoxy-1-butanol, or a hydroxy ester, such as ethyl lactate, and the second solvent is a lower alkyl alcohol, such as isopropanol. Alternatively, the first solvent may be a ketone or an alkyl ester.

Abstract: Process for removing nitrogen oxides from the flue gases of a soda recovery boiler of a pulp mill. In the method, to the flue gases of the soda recovery boiler is at first fed an oxidizing agent, such as chlorine dioxide or ozone, which oxidizes nitrogen oxide to nitrogen dioxide. Subsequently, the flue gases are led into a flue gas scrubber, in which a reagent coming from the circulation of chemicals of the pulp mill is injected into the flue gases, which reagent brought into contact with the nitrogen dioxide reduces the nitrogen dioxide to nitrogen. The flue gas containing nitrogen is led out of the scrubber and the oxidized reagent is led back to the circulation of chemicals of the pulp mill.
