Abstract: STEERING APPARATUS FOR SMALL OUTBOARD MOTORS                 Abstract of the Disclosure An outboard motor has a steering tiller handle assembly attached to the driveshaft housing and pivotally mounted within a swivel mounting bracket assembly.  The swivel bracket assembly includes a split tubular element within which a split tubular section of the steering arm assembly is notably mounted and lo-cated encircling a tubular portion of the driveshaft housing.          Upper and lower annular rubber mounts are located between the upper and lower end of the steering tubular section and the driveshaft housing.  Each mount is formed with a first pair of axial slots formed in diametrically opposite sides of the mount and projecting inwardly from one end.  A similar pair of slots offset by 90° from the first set of slots extending inwardly from the opposite end of the annular mount,  The driveshaft housing and the steering tubular section are provided with cor-respondingly offset projections adapted to mate with the slots in the annular mounting.  Upper and lower sleeve bearings are located between the tubular section of the swivel bracket as-sembly and the steering arm assembly.  The driveshaft housing is also employed as the exhaust passageway and includes a pair of openings aligned with the chamber to the steering assembly, the aft portion of which opens to the tubular section of the swivel bracket assembly.  The outer wall of the swivel tubular section is provided with a generally U-shaped passageway with a closed end aligned with an exhaust opening and extending up-wardly and then downwardly to discharge exhaust gases downwardly toward the water.

Abstract: ABSTRACT OF THE DISCLOSURE A trough-type scale trap for use with a refinery or chemical plant reactor having a catalyst bed subject to plugging by fine particles is disclosed. Compared to prior art traps, the trough-type scale trap of the invention is characterized by a larger volumetric capacity and screen area and is substantially easier to construct and to install or remove from closed reactor vessels than conventional traps. Its typical embodiment is as a series of parallel troughs having rectangular openings and disposed chordally across the reactor normal to the direction of flow. In one embodiment, the trough is a rectangular parallele-piped; in another embodiment, the substantially rectangular opening is reduced by tapering to a bottom significantly smaller than the inlet opening.

Abstract: ABSTRACT          An element for a terminating and testing unit for use in a telecommunications exchange is described.  The element comprises a strip of insulating material having slots in opposite faces thereof in which conduct-ing members are housed.  The conducting members project from one edge of the strip to provide tag connection facilities for conductors and pairs of members interengage adjacent the other edge of the strip to provide socket connection facilities.  A plug can be inserted between a pair of conducting members to break the contact of the members and establish contact between conducting surfaces of the plug and the members.  The elements can be clamped together side-by-side to form a terminating and testing unit.          Such a unit is very economical in its use of space.

Abstract: NONINVERTING CURRENT MODE LOGIC GATE      Abstract of the Disclosure A high speed bipolar noninverting current-mode logic AND gate is the basic building block for a current-mode logic family.  The AND gate comprises a current steering differential pair of transistors, a pair of dual emitter input transistors, a dual emitter reference transistor, an output resistor and a fixed current source. The conducting state of the current steering transistor pair is so controlled that a logic "one" at the base electrodes of both input transistors produces a logic "one" at an output terminal taken from the collector electrode of the reference transistor.  Further, a logic "zero" at both input transistors produces a logic "zero" at the output terminal and finally the condition of a "zero" at one input and a "one" at the other input produces a "zero" at the output. This result is attained as a consequence of control of the conduction state of the current steering pair so as to provide the same current level through the reference transistor for the "zero-one" input as for the  "zero-zero" input, thus producing the noninverting AND function.

Abstract: ABSTRACT OF THE DISCLOSURE      A heat actuated valve comprises a base adapted to be mounted on a fire extinguisher container. The base includes a passage communicable with the container interior. A pair of stop fingers extend forwardly from the base. A fusible element interconnects the stop fingers. The base, stop fingers and fusible element are of one-piece, integral construction. A plunger is slidably mounted in the passage and includes a passage-blocking portion which blocks the passage when the plunger abuts the stop fingers during a fire sensing mode of operation. The plunger is slidable rearwardly to shift the passage-blocking portion to a first passage-opening position to allow the container to be filled. The plunger is operable, in response to melting of the fuse, to spread the stop fingers apart and travel forwardly sufficiently to shift the passage-blocking portion to a second passage-opening position, enabling the container contents to be discharged.

Abstract: ABSTRACT OF THE DISCLOSURE     A concentrated suspension of sodium carbonate anhydride is obtained by countercurrent contacting of a high pres-sure steam and a suspension of sodium bicarbonate or sodium sesquicarbonate in a thick solution of sodium carbonate.  The decomposition reaction is promoted to near completion by maintaining the reaction temperature above 150°C to realize a high HCO3- ion concentration in the solution.  The sodium carbonate anhydride sus-pension is cooled to cause transition of the anhydride to the monohydrate, followed by the separation of the crystalline monohydrate from the mother liquor.  Calci-nation of this monohydrate gives a dense soda ash featuring a high purity and a uniform particle size, while the mother liquor is recycled for the preparation of the sodium bicarbonate suspension.
