Abstract: ABSTRACT OF THE DISCLOSURE        A ligating clip is provided with first and second legs joined at their proximal ends by a hinge and terminating at their distal ends by a latch means for holding the clip latched closed when the legs are squeezed together.  One of the legs is provided with a base defining guide means for engaging portions of an instrument that may be used to apply the clip.  An instrument is provided to apply the clip and includes first and second handles mounted together for pivotal movement.  Each handle extends beyond the pivot axis to form a clip closing jaw.  The first handle includes a guideway for receiving a plurality of the open clips.  A pusher member is provided within the first handle to push the clips to the jaw region.  A spool is mounted for rotation in the first handle jaw and includes a forward flange and a rearward flange between which the front clip of the row of clips may be positioned. An L-shaped rod extends from the spool and is pivoted in one direction by one of the handles when the handles are closed to rotate the spool to permit passage of the closed clip from the jaws after the jaws are subsequently partially opened.  The rod is also pivoted in a second, opposite direction after the handles are partially opened to orient the spool to block feeding of the next clip beyond the jaw region.

Abstract: Abstract of the Disclosure A system and process for removing asbestos from structures includes all components necessary for safe removal of the material in a van body that can be moved easily from one site to another. The system includes mechanism for sealing of selected areas, with tubing connecting the selected sealed areas to a separator chamber in the van body. Air pressure is lowered within the sealed enclosed area and airflow is maintained through the tube to the separator chamber. Water jets are also directed within the tube toward the separator chamber. Asbestos can be removed from the structure within the enclosure and deposited into the tube where it flows in an air and water stream to the separator chamber. There the larger asbestos particles are allowed to drop into a collection tank. Remaining fibers are filtered by a series of air filters until the air is safe to be discharged into the atmosphere. Airflow and pressure differential is produced by one or more of a series of valved fan units near a discharge end of the chamber. An auxiliary airflow tube and return air (make-up air) tube can also be connected between the chamber and enclosure.

Abstract: Abstract of the Disclosure A modular construction of an interface board for mounting electrical connectors comprises a plurality of interlocked modular blocks on which the connectors are mounted.  Each side face of each block comprises one or more sets of locking elements which engage with a mir-ror-image set of locking elements on another of said blocks to prevent relative lateral motion between the blocks or structures.  Motion of the blocks or structures away from each other, in a direction normal to their mated side faces, is prevented by providing a tapered mortise in each of said side faces, the adjacent mortises of ad-jacent interlocked blocks or structures being in mutually confronting, aligned relationship to each other so that the tenons of a double dovetail wedge can be inserted into both mortises simultaneously to hold them in fixed position.  A resilient hooked projection integral with the wedge enrages a detent in one of the block side faces when the wedge is fully inserted, to prevent its later loosening and accidental removal.

Abstract: ABSTRACT           A conveyor system wherein sheets      are conveyed from a cutter     or the like at a given speed, are increased in speed before passing through a vacuum conveyor shingling section    , are slowed down at the shingling section and then normally proceed at the slowed-down speed to a stacker     which is adapted to stack a fixed number of sheets before discharging a stack.  The sheets are basically handled in accordance with the device disclosed in U.S. Patent 4,200,276.  To prevent scattering of the sheets during shingling due to high input conveyor speeds and the like, the vacuum conveyor shingling section     includes a second (or pre-shingling) conveyor      upstream of the original shingling conveyor     .  The pre-shingling conveyor operates at a relatively high rate of speed while the original shingling conveyor operates at a relatively low rate of speed (which nevertheless may be as high as the device of the patent) relative to the sheet input speed.  A setting control      is provided to pre-set the pre-shingler conveyor speed in correlation with the input speed of the sheets and the length of the individual sheets.  The pre-set pre-shingler conveyor speed remains constant during operation of the device.  Conveyors            downstream of the pre-shingling conveyor      run at speeds which are corre-lated to the speed of the supplemental pre-shingling conveyor    .

Abstract: Abstract A servo amplification system is created particularly for heavy construction equipment, but has a general utility that is much broader.  The system utilizes a hydraulic analog system with a separate subsystem for each dimension of motion.  The operator moves the operative element, such as the backhoe bucket, of the analog replica which ordinarily would be situated in the cab of the backhoe or other piece of equipment. A small hydraulic cylinder operative in response to movement at each articulated connection of the backhoe operates a pilot valve which controls a pilot piston mechanically linked to the drive valve of the drive cylinder of the corresponding articula-tion in the actual backhoe.   A feedback system comprising a mechanical link from the actual drive piston to a feedback cylinder and piston delivers hydraulic fluid back to the inlets of the pilot valve in such a way as to cancel the pilot orders from the initial control cylinder.  The resulting action is virtually perfect analog simulation by the actual backhoe of the movements of the replica backhoe.

Abstract: INFORMATION PROCESSING SYSTEM FOR COMPACTION AND REPLACEMENT OF PHRASES                        Abstract An information processing system is disclosed which provides a writer with acceptable replacement phrases to substitute for trite phrases in a manuscript text.  The replacement phrases are grammatically equivalent to the trite phrases and can be immediately inserted into the text without further alteration.  The system compacts and replaces phrases with grammatically equivalent phrases conforming to conventional grammatical constraints of the original phrase.  Reference lists of words corresponding with each other are built for enabling the replacement of a phrase with a grammatically equivalent phrase.  The text to be analyzed is scanned to match a source phrase with a family of target phrases.  A bit map created by hashing a word pair consisting of the least frequent word and a proximate less frequent word in the source phrase and the target phrase is used.  The scanning is continued until a match is obtained in the bit map to indicate that a suitable target phrase has been found.  The target phrase is then displayed.

Abstract: IMPROVING THE TRAINING OF MARKOV MODELS   USED IN A SPEECH RECOGNITION SYSTEM     ABSTRACT OF THE DISCLOSURE     In a word, or speech, recognition system for decoding a vocabulary word from outputs selected from an alphabet of outputs  in  response to a communicated word input wherein each word in the vocabulary is represented by a baseform of at  least one probabilistic  finite  state model and wherein each probabilistic model has transi-tion probability items and output probability items and wherein a value is stored for each of  at  least some probability items, the present invention relates to ap-paratus and method for determining probability values for probability items by biassing at least some of the stored values  to enhance the likelihood that outputs generated in response to communication of a known word input are produced by the baseform for the known word relative to the respective likelihood of the generated outputs being produced by the baseform for at least one other word. Specifically, the current values of counts --from which probability items  are derived--  are ad-justed by uttering a known word and determining how of-ten probability events occur relative to (a) the model corresponding to the known uttered "correct" word  and (b) the model of at least one other "incorrect" word.          The current count values  are  increased based on the event occurrences relating co the correct word and are reduced based on the event occurrences relating to the incorrect word or words.

Abstract: MEANS AND TECHNIQUE FOR CASTING METALS  AT A CONTROLLED DIRECT COOLING RATE                        Abstract Close control of the direct cooling rate is achieved by bubbling a substantially insoluble gas into the curtain-forming coolant as it is about to discharge onto the emerging ingot.  The resulting bubble-entrained curtain of coolant experiences an increased velocity, and the increase is not accompanied by a reduction in the thermal conductivity of the coolant.  Instead,  the bubble-entrained coolant appears to have a scrubbing effect on the metal, which breaks up any film and reduces the tendency for film boiling to occur at the surface of the metal, thus allowing the process to operate at the more desirable level of nucleate boiling, if desired.  This in turn makes it possible to regulate the cooling rate by selective use of the bubbling effect, including turning the effect on and off to allow film boiling to occur when desired such as in the butt forming stage of the casting operation.  The bubbling effect can also be used to regu-late the cooling rate when the coolant is in short supply and/or hotter than desired.
