Abstract: ABSTRACT This invention relates to methods, apparatus and articles for sys-tems comprising optical fibers, in particular for feeding an optical signal into an optical fiber through the buffer thereof and for withdrawing an optical signal from an optical fiber through the buffer thereof.  Preferably this is achieved with the aid of an optical coupling means which contacts and conforms to the surface of the buffer at a bent portion of the fiber.  The coupling means can for example be a polysiloxane.  In a preferred aspect, the invention provides an apparatus and method for axially aligning the ends of optical fibers.  The apparatus comprises means for holding two fibers so that the fiber ends are approximately abutting and axially aligned, adjacent means for passing an optical signal into one of the fibers through the buffer there-of, and adjacent means for withdrawing that signal from the other fiber through the buffer thereof.  At least one of the holding means is movable to maximize the withdrawn optical signal and thus to align the fibers.  Prefer-ably the apparatus comprises means for joining the ends of the aligned fibers. The invention also includes novel splices which can be made in this way and novel splicing aids for use in the method.  Suitable apparatus is illustrated in the drawing.

Abstract: ABSTRACT OF THE DISCLOSURE     An improved process for recovering and recycling coagulant present in water treatment sludges.  The improvement comprises several steps.  First, enough acid is added to the sludge to solubilize most, but not all, of the coagulant in the sludge.          Next, the acid-treated sludge is filtered on a non-mechanical horizontal filter to produce the recovered coagulant in solution as the filtrate.  The recovered coagulant has a greater coagulative effect, when later recycled to treat raw water, than the mole equivalent of commercial coagulant.  A portion of the recovered coagulant is discarded to control the increase in concentration of unwanted impurities in the recovered coagulant.  Finally, this process permits neutralization and later removal of the filtered sludge on the surface of the non-mechanical horizontal filter.

Abstract: INK DROP DUPLICATING SYSTEM          Abstract of the Disclosure An ink drop duplicating system employs a plurality of angularly extending ink drop print heads to reproduce an original document.  Each printing head produces a row of drop streams which are individually controlled to deposit printing drops at a plurality of printing positions along a line extending perpendicular to the major axis of the printing head.  Printing control information for the ink drop printing heads is generated by a photosensing array which extends across one major dimension of an original document and which is scanned across the other major dimension.  Scanning data is stored on a magnetic disk.  After one or more original documents have been completely scanned, the scanning data is read from the magnetic disk and reorganized to produce drop control signals for the ink drop printing heads.
