Abstract: ABSTRACT OF  THE DISCLOSURE         A novel rotary compressor is provided herein.  It includes a center housing and front and rear side housings, a rotary sleeve mounted for rotation in the center housing, a rotor eccentrically disposed in the rotary sleeve, the rotor having a plurality of vanes radially, movably fitted therein, an air bearing room disposed between the inner periphery of the center housing and the outer periphery of the rotary sleeve, and a pair of discharge and suction chambers.  The novel compressor includes at least one high-pressure passage formed in the compression side of the center housing and internally connected to air compressed in the rotary compressor. plurality of throttles communicate with the compression side, inner periphery of the center housing from the high-pressure passage, the high pressure passage forming a circular arc having a subtended angle of less than 170 degrees. In this ways, the air-bearing room is supplied with air compressed in the rotary compressor in order to floutingly support the rotary sleeve.  By this structure the rotor is essentially prevented from scuffing the inner periphery of the center housing when it is moved aside to the compression side inner periphery of the center housing by the high-pressure air in the compression working space.

Abstract: ABSTRACT          There is disclosed a connector for colinear axial alignment of a pair of optical waveguides, comprising:  at least three elongate resilient rod members in parallel relationship defining an interstitial passageway therebetween.  Each of the rod members has a larger diameter at first and second opposite ends thereof, and a smaller diameter segment intermediate the ends.  The passageway admits respective waveguides therein from each end, with forward end surfaces of the waveguides positioned in an opposed adjacent location intermediate of the rod members length.  A sleeve of elastomeric material having an external stepped profile has an axial passageway receiving the rod members, the passageway being sectionally profiled for holding the rod members parallel.  Crimping collars can be moved towards each other to compress the sleeve and exert increasing radial pressure upon the smaller diameter rod segments.

Abstract: ADAPTIVE AUTOMATIC DISCRETE UTTERANCE RECOGNITION                      Abstract Adaptive training of a system for discrete utterance recognition during continuous speech permits single prototype utterances to be adapted to the needs of the talker, during operation, without tedious multiple recitation for training of prototypes.  Initial training of the recognition system is by a single utterance (or simulation) of a prototype vocabulary.           Operation proceeds, so long as utterances are recognized, until an unrecognized utterance is detected.  The system then prompts a choice of prototype vocabulary keyword candidates, which the talker may then choose and utter.

Abstract: Abstract of the Disclosure:     In an automatic call transfer system for use in carrying out transfer of a terminating call from one of telephone sets (T) to another through an exchange (11), a person identification number (ID) is assigned to each of persons movable in a limited area and is generated from a transmitter (TX) conveyed by each person.          The limited area is divided into a plurality of zones (Z) which are defined by receivers (RX) connected through subscriber lines to the exchange, respectively, and which include at least one of the telephone sets, respec-tively.  The person identification number is produced from a transmitter (TX) conveyed by each person and is received by a selected one of the receivers in the zone for the selected receiver to be sent through one of the subscriber lines (L) to the exchange.  A line number of the one subscriber line is memorized in a memory of the exchange in correspondence to the person identification number and is changed as each person moves in the limited area.  Responsive to the terminating call carrying the person identification number, the exchange searches the memory to detect the line number memorized therein and to transfer the terminating call to one of the telephone sets indicated by the memorized line number.

Abstract: ABSTRACT OF THE DISCLOSURE     Data recording is self-archiving by non-delete recording combined with a directory that grows with each recording in a manner that all previous recordings related to the respec-tive files or data sets are pointed to in the directory.          Non-delete recording is applicable to those record media exhibiting indelible characteristics, such as write-once optical media and to rewritable media, such as magnetic recording media of all types.  Each directory entry is identified by file or data set name and has one field for each data segment currently a part of the file or data set.          Each field has a pointer to its represented data irrespec-tive of when it was recorded.  Each directory entry also points to the entry associated with the immediately preced-ing recording operation on any part of the file or data set such that data changes can be traced using the directory. The directory is stored in one address end portion of the data storing medium while the data is stored in the opposite address end portion--the directory is preferably at the low addresses while the data is at the high addresses.  The directory recording is at ever increasing addresses while the data recording is at ever decreasing addresses.

Abstract: IMPROVED APPARATUS FOR AGITATING   AND PUMPING A LIQUID SLURRY Abstract of the Disclosure An improved apparatus for agitating and pumping a liquid slurry, such as manure slurry.  The apparatus includes a vertical column mounted for rota-tion about its axis in a pit or vessel containing the liquid slurry.  A motor-pump unit is mounted for rota-tion about the axis of the column and is also mounted for vertical sliding movement relative to the column. To guide the motor-pump unit in vertical movement on the column, a generally C-shaped guide on the motor pump unit rides on a flat plate-like track on the column.  The upper end of the track terminates at a level slightly above the pit, so that by elevating the motor pump unit, the motor-pump unit can be freely removed from connection with the column.  The upper end of the pit is enclosed by a closure plate having a cen-tral opening, and a rotary deck plate carried by the column encloses the opening and rotates with the column relative to the closure plate.  The deck plate has an aperture through which the motor-pump unit can be raised during agitation of the liquid slurry and the aperture is enclosed by a hinge cover.  Extending down-wardly from the cover is a cam member which is engaged by the motor-pump unit as the motor-pump unit is ele-vated to lift the cover to an open position.  The power cable which is connected to the motor-pump unit is biased upwardly by a counterweight to prevent entangle-ment of the cable when the motor-pump unit is in an upper position.

Abstract: ABSTRACT A method for quantitatively distinguishing seismic events on a seismic record for inferring changes in the geological character of the subterranean forma-tions.  Reflection coefficients are obtained for such seismic events and a first set of attributes indicative of amplitude variations in the offset seismic signals corre-sponding to the seismic event as a function of incident angle are obtained therefrom.  The first set of attributes provide a seismologist with a diagnostic tool for quanti-tatively evaluating subtle changes in the seismic event. A second set of attributes which are functions of the first set of attributes provide the seismologist with additional diagnostic tools for evaluating subtle changes in the seismic events.
