Abstract: Abstract of the Disclosure A system for recognizing a continuously spoken word sequence with reference to preselected reference words with the problem of coarticulation removed, comprises a pattern memory for memorizing demi-word pair reference patterns consisting of an initial and a terminal reference pattern segment for each reference word and a word pair reference pattern segment for each permutation with repetition of two words selected from the preselected reference words.  A recognition unit is operable as a finite-state automaton on concatenating the demi-word pair reference patterns so that no contradiction occurs at each interface of the reference patterns in every concatenation.  It is possible to use the automaton in restricting the number of reference patterns in each concatenation either to an odd or an even positive integer.

Abstract: CIRCUIT BOARD FABRICATION               LEADING TO INCREASED CAPACITY     Abstract Printed circuit boards having a plurality of circuit layers are produced using a specific processing sequence.  A copper-clad substrate is first patterned in a desired configuration to produce the first layer of the printed circuit board.  The patterned metallization is then covered with a specifically formulated energy sensitive material.  The energy sensitive material is delineated in a desired pattern and developed to uncover portions of the underlying metallization pattern.  The entire substrate is blanket-cured to produce a rigid layer having openings in appropriate places.  The openings are metallized and a second copper pattern is produced on the cured polymer by conventional metallization and lithographic techniques.  If desired, the process is repeated until a suitable number of copper patterned levels are obtained.

Abstract: ABSTRACT         Apparatus for cleaving optical fibers is disclosed.          The apparatus includes a bore for receiving a fiber and two spaced clamping members for engaging and holding the fiber at two respective longitudinal locations in the bore.  The clamping members are resiliently biased relatively away from each other so as to place the portion of the fiber between the two clamping members under tension.  A scribing tool has a sharp point engageable with the fiber on the portion under tension and a backing member holding the fiber in opposition to the sharp point.  The scribing tool is rotatably mounted on the apparatus so that the point and backing member can be rotated completely around the fiber which then breaks at the resulting scored line.      The result is a precise 90° face unaccompanied by appreciable bending or twisting.

Abstract: ABSTRACT OF THE DISCLOSURE           A fluid diffuser for dispersing a gas or liquid into a body of receiving liquid in which it is immersed.  The diffuser includes a rotatable shaft, a thin disk-like member mounted for rotation on the shaft, and an annular ring positioned adjacent the outer perimeter of the disk like member.  At least one of the top and bottom walls of the annular ring is porous.  These top and bottom walls define a fluid plenum, into which gas or liquid under pressure is introduced to be emitted from the plenum as small, nascent fluid spheroids on the surface of the annular ring.  The boundary layer flow from rotation of the disk-like member within the body of receiving liquid shears fine gas bubbles or liquid particles from the foraminous surface or surfaces of the annular ring.  The annular ring may be fixed, or rotatable in the opposite annular direction from the rotation of the disk.  Impeller blades may be mounted on the top and/or bottom surfaces of the rotatable disk.  The fluid diffuser is disclosed immersed in a flotation tank with a system of baffles to define a mixing zone at the bottom of the tank and a flotation zone at the top of the tank.  Preferred embodiments of the diffuser include features to improve the mixing as well as diffusing action of the device.
