Abstract: Abstract of the Disclosure:     A connected word recognition system operable according to a DP algorithm and in compliance with a regular grammar, is put into operation in synchronism with successive specification of feature vectors of an input pattern.  In an m-th period in which an m-th feature vector is specified, similarity measures are calculated (58, 59) between reference patterns representative of reference words and those fragmentary patterns of the input pattern, which start at several previous periods and end at the m-th period, for start and end states of the reference words.          In the m-th period, an extremum of the similarity measures is found (66, 69, 86), together with a particular word and a particular pair of start and end states thereof, and stored (61-63).  Moreover, a particular start period is selected (67, 86) and stored (64).          A previous extremum found and stored (61) during the (m-1)-th period for the particular start state found in the (m-1)-th period, is used in the m-th period as a boundary condition in calculating each similarity measure.  After all input pattern feature vectors are processed, a result of recognition is obtained (89) by referring to the stored extrema, particular words, particular start states, and particular start periods.

Abstract: WET-MICROCONTRACTED PAPER  AND CONCOMITANT PROCESS                          Edward R. Wells and Thomas A. Hensler ABSTRACT      High bulk, absorbent piper having a relatively high MD elongation at rupture, and a substantially greater stress/strain modulus in the lowest one-third of its range of MD extensibility -- preferably when wet -- than equally machine-direction-stretchable, purely dry-foreshortened (e.g., dry-creped) paper having substantially identical MD elongation at rup-ture.  The process includes a differential velocity transfer of a wet-laid embryonic web having relatively low fiber consistency from a carrier to a substantially slower moving, open-mesh transfer fabric having a substantial void volume; and thereafter drying the web while precluding substantial macroscopic rearrangement of the fibers in the plane of the web.  The differ-ential velocity transfer is effected without sub-stantial compaction of the web by avoiding substantial mechanical pressing, centrifugal slinging, air blast-ing, and the like.  The MD stress-strain property of the paper when wet is directly related to the magnitude of the differential velocity at transfer; to the magnitude of the wet-strength property of the paper; and to the topography of the transfer fabric.

Abstract: ABSTRACT      A modular lock unit including a carrier frame and a heavy base plate and framework is positioned in a steel door jamb.  A lock solenoid and an unlock solenoid are connected to opposite ends of a bolt cam slide extending through a vertical slot in a horizontally reciprocal bolt so that vertical movement of the slide effects camming movement of the bolt between an extended locking position and a retracted unlocking position.  The slide includes a central slot oriented at approximately 45° and having vertical deadlock end portions.  A lock pin in the bolt extends through the central slot of the slide and enters the deadlock portion of the bolt when in either its extended or retracted position.  Camming movement of the bolt is effected by the front and rear edges of the slide engageable with front and rear follower surfaces in the slot in the bolt.  A control circuit includes a central main control switch for the locking system positioned in a guard station and also includes electric key switches for giving the inmate the permissive ability to unlock his door under the control of the guard.  The circuit also provides for automatically locking the door when it is closed and for automatically retracting the bolt in the event that any obstruction is provided in the strike in the door so as to preclude damage to the solenoid employed for extending the bolt.  A time delay relay terminates power to the lock solenoid after it has been actuated for 1.5 seconds so as to preclude solenoid damage.  The slide for moving the bolt to its extended position is supported by heavy slide bearing surfaces in the support framework so that any force applied to the bolt is not conveyed to the solenoid but is absorbed by the framework and the slide member.

Abstract: ABSTRACT             This invention relates to a switching system testing arrangement which uses a looparound circuit, into which a test signal is injected and received to determine whether the loop is functioning properly.  The system provides means for testing individual switches (or equivalent time division counterpart), individual loops and links between switching stages and the network, complete loops between peripherals, short loops between peripherals and their local control units, or any loop that can be set up within the system, without incurring loss of use of parts of the system which would otherwise be required to obtain the loop but are not of interest to test.  The control data and test signals are applied, to set up the loop and into the loop respectively, via message transmission paths which are separate from the loop under test.  Accordingly any part of the communication circuit system can be isolated for test, reducing substantially the time overhead for determining whether a switching element or stage, or link is operating properly.

Abstract: NOVEL METHOD AND APPARATUS FOR RAPIDLY DETERMINING         THE MOISTURE CONTENT OF A SUBSTANCE                             ABSTRACT           A method and apparatus is disclosed for rapidly determining the moisture content of a substance.  An area of one surface only of the substance is subjected to a predetermined intensity of radiant energy for a selected period of time and the temperature rise is measured.  The rise in the surface temperature of the substance such as pieces of wood, is approximately inversely proportional to the moisture content of the wood and thus is easily determined.  This is obtainable by transporting the substance on a fixed speed conveyor past a heat source, variations in the rise and fall in the surface temperature readings immediately following the application of heat are representative of its moisture content;  low readings indicating high moisture content whilst high readings being indicative of low moisture content.

Abstract: Abstract An arrangement for fastening a roll ring     to an overhung roll shaft     by means of a taper sleeve which transmits essentially the entire torque and which is loaded axially by a spring      supported on an abutment     adjustable on the free end of the roll shaft.  The roll ring can be exchanged easily because of a cylinder part      arranged radially within the spring.          This cylinder part forms a first annular cylinder space for prestressing the spring, with which it interacts via a flange, and a second cylinder space      for drawing off the taper sleeve, to which it is connected via en-gagement means     .  The spring and the hydraulic devices can remain in place when a roll ring is assembled and re-moved, because their outside diameter is less than the bore of the roll ring.
