Abstract: ABSTRACT OF THE DISCLOSURE A lock mechanism particularly for doors having a narrow stile, wherein a unique arrangement of components provides greater security and facilitates manufacture and installation, as characterized by a heavy pivotally swingable main bolt connected at its inner end to one end of a rocker actuating lever, the end of the lever being provided with a unique escape-ment for the release and control of the movement of the rocker arm by an associated manually rotatable key-actuated cam extension, to move the main bolt between locked and unlocked positions. An important feature of the escapement resides in a unique arrangement of parts which is not critical as to the dimensions of the actuating cam extension, and which readily accom-modate to actuating cams that may vary materially in their dimensions. The escapement also enables a better and more symmetrical resolution of the opera-ting forces in a manner which materially contributes to the obtainment of maximum security. The lock mechanism is also arranged to include an improved latching assembly for mounting in operative association with the main bolt lock mechanism in a manner to provide both locking and latching operations, respec-tively, by means of a locking bolt and a latch member, and wherein the latch member is spring-urged to a latched position and is independently operably by a latch handle, knob or the like to an unlatched posi-tion. The locking bolt is also arranged to be key-actuated in a normal manner, the key being also further operable, in an unlocked position of the locking bolt, to move the latch member to a retracted or unlatched position.

Abstract: ABSTRACT OF THE DISCLOSURE         A device for setting a hook in the mouth of a fish has a base supporting and an upwardly inclined arm.  The front or cantilevered end of the arm supports a freely suspended tension member which is fitted at its lower end with a hook-like finger. Beneath the finger, there is trigger mechanism including a trigger plate and a latch bar.   The finger engages the latch bar so that the mechanism is held in a set position by the upward pull exerted by the tension member.  A fishing rod is placed alongside and mainly to the rear of the device so that a tip portion only of the rod rests on the trigger plate in a position over the finger and with the fishing line suspended in the water.          When a fish nibbles at the bait, the trigger mechanism is released causing the finger to snatch the tip of the rod and therefore the line upwardly to hook the fish.

Abstract: ABSTRACT      A method for manufacturing semiconductor device by the master slice method, in which various kinds of semi-conductor devices are manufactured through utilization of a common master pattern and a plurality of kinds of wiring patterns.  A number of bipolar transistor portions, each having a plurality of the same emitter regions are formed by the common master pattern in a semiconductor substrate and the plurality of emitter regions in the bipolar transistor portions are selectively used by the wiring patterns to form bipolar transistors of different DC characteristics.  When manufacturing many kinds of semiconductor devices by this method, the area which would be wasted on the semiconductor substrate is greatly reduced, thus providing for enhanced area efficiency.

Abstract: CONTEMPORANEOUS FABRICATION OF DOUBLE HETEROSTRUCTURE LIGHT EMITTING       DIODES AND LASER DIODES USING LIQUID PHASE EPITAXY Abstract of the Disclosure In the manufacture of double heterostructure laser diodes using liquid phase epitaxy a source crystal precedes the laser substrate crystal through the process to ensure saturation of the various melts from which epitaxial growth is obtained.  The source crystal has hitherto been discarded.  The source crystal, since it immediately precedes the substrate crystal, also experiences epitaxial growth of a heterostructure but with heterostructure layer thicknesses unsuited for laser diode fabrication.  By suitable processing of the source crystal after it is formed with a heterostructure, light emitting diodes can be produced so contributing to a 50% reduction in materials cost.          _ j _                          -i-

Abstract: ABSTRACT           In the manufacture of an optical cable element comprising a tube of plastics material loosely housing at least one optical fibre, a water-impermeable medium in a liquid or semi-liquid state is applied to an advancing optical fibre immediately upstream of an extruder in such a way and under such a pressure that the advancing optical fibre with water-impermeable medium therearound passes into the extruder.  After a tube of polymeric material has been extruded around the advancing optical fibre and the surrounding water-impermeable medium in such a way that the internal diameter of the tube is greater than the overall diameter of the optical fibre and the extruded tube has been drawn down and so treated that the molecules are longitudinally oriented, the space in the tube not occupied by the optical fibre is filled with water-impermeable medium of a jelly-like nature.

Abstract: ABSTRACT OF THE DISCLOSURE         A dual orbit sprayer assembly particularly for use in continuous coaters.  The invention includes a pair of rods rotatable about a central shaft, thereby defining a primary orbit.  At the end of each rod are a pair of arms rotatable about their own individual shafts, such arms having spray nozzles at the ends thereof.  Rotation of the arms causes the nozzles to pass about secondary orbits having their centers maintained upon the primary orbit. Rotation of the shafts is achieved in one embodiment by a motor driving the central shaft with a sprocket and chain interconnection being provided among the shafts.  In another embodiment, the central shaft consists of inner and outer concentric shafts, each driven by a uniquely associated DC motor.  The inner shaft controls the rotational movement of the rods, while the outer shaft is interconnected with the remaining shafts to independently control rotation of the arms.

Abstract: A METHOD OF ENTERING FIELD DEPENDENT CRITERIA FOR SELECTING RECORDS OF SPATIALLY RELATED DATA IN AN INTERACTIVE TEXT PROCESSING SYSTEM                      Abstract An improved method is disclosed for assisting the operator of an interactive text processing system. The method assists the operator in entering interac-tively selection criteria to be used in selecting records from the existing file.  The improved method involves displaying to the operator the header portion of the existing file, along with a predetermined number of "qualifying rows" in response to the opera-tor having identified to the system the task to be accomplished and the name and the location of the existing file in the system.     The method further involves movement of the cursor vertically and horizontally to row and column positions for entering of the selection criteria. After entering criteria into the displayed rows, the next operation of the cursor down key while in the last row is interpreted as an instruction to the system to add an additional row so that another "logical OR" selection criteria can be added to the previous criteria.
