Granted: 1993-09-21
Abstract: ABSTRACT OF THE DISCLOSURE           A system for generating indicia of registration error between the respective printing units of a web-fed, four-color printing press.  An optical line scanner is disposed over a web to generate signals indicative of the brightness level of successive nominal pixels along a line transverse to the motion of the web.  The respective printing units each generate registration marks on the web, the rela-tive positions of which are indicative of the relative cyclical (rotational) and transverse (lateral) positions of the printing units with respect to the web.  As the web moves past the scanners, successive line scans generated by the scanner provide the equivalent of a two-dimensional raster scan of a strip of the web centered on the expected center line of registration marks produced by the respective print-ing units.  The centers of the respective registration marks are determined, and the cyclical (rotational) and transverse (lateral) positions of the printing unit adjusted, in accord-ance with deviations from expected relative positions.  The use of symmetrical marks and, in particular, right-angled diamonds, is disclosed for facilitating calculation of the center of the marks.

Title: Process for removal of mercury vapor and/or vapor of noxious organic compounds and/or nitrogen oxides from flue gas from an incinerator plant
Inventor: MOLLER JENS T
IPC: B01D53/34

Granted: 1992-05-12
Abstract: A process for removal of mercury vapor and/or vapor of noxious organic compounds and/or nitrogen oxides from flue gas from incinerator plants.            A B S T R A C T            The ability of activated carbon to remove mercury and noxious polyorganic  matter,  especially  chlorodibenzo-dioxins and -furans from incinerator flue gases is uti-lized in an efficient manner by suspending powdery acti-vated carbon in the flue gas in connection with a con-ventionel spray absorption process in which the acidic components of the flue gas are neutralized by means of basic absorbents.  The cooling of the flue gases in the spray absorption process provides an efficient adsorp-tion onto the powdery activated carbon and the separa-tion of said powdery activated carbon from the flue gas is substantially facilitated by the presence of the par-ticulate material  formed by the spray absorption pro-cess.  Also an improved removal of nitrogen oxides is obtained.

Abstract: 42073 CAN 2A . Pad Forming Method A method for forming pads (11) of pressure sensitive adhesive coated sheets with similar discontinuities (e.g., printed indicia (10) or openings (13)) on the sheets substantially aligned. A strip (16) of pressure sensitive adhesive coated material is helically wound around the periphery of a roller (18) to form a roll (20) comprising a multiplicity of overlying layers of the strip (16) by rotating the roller (18) about its axis to pull the strip (16) along a predetermined path (22) onto the roller (18). Discontinuities are formed on the strip (16) along the predetermined path (22) at locations that are progressively increasingly spaced apart to compensate for the increasing circumference of the roll (20) and which result in at least one set of discontinuities being located along the periphery of the roller (18) in substantial alignment radially outwardly of the roller (18); and pads (14) containing such aligned discontinuities are then cut from the roll (20).

Abstract: "RECOIL SYSTEM FOR WEAPONS WITH A RECIPROCATING BREECH BLOCK"                  ABSTRACT OF THE DISCLOSURE        The present invention relates to a firearm, generally of the automatic or semi-automatic type, having a reciprocating breech block normally biased into closed position by a primary recoil absorption system including a spring, the improvement comprising providing a secondary spring-biased recoil absorption system cooperating with the primary one during a portion of the retraction stroke of the block to slow down the movement of the latter before becoming inactive while the primary system slows the block to a stop and reverses its direction and then becoming active to once again cooperate with the primary system during a portion of the return stroke of the block to speed up its return to its original position.  The invention also encompasses the improved method for controlling the movement of the breech block in the aforementioned type of weapon during its firing cycle wherein such movement during its initial and final stages is supplemented and abetted by a secondary spring-biased recoil absorption system cooperating with the primary one while, at the same time, leaving the primary system solely responsible during the remainder of the cycle to stop the block and reverse its direction.
