Abstract: ABSTRACT OF THE DISCLOSURE           This invention relates to a polymerization reaction vessel having a coating on the inner surfaces thereof resulting from applying thereto a coating composition containing, as a primary ingredient, a straight chain or branched poly-aromatic amine dissolved in an aqueous alkali metal hydroxide solution.  When polymerizing olefinic monomers, such as vinyl halides, vinylidene halides, and vinylidene monomers having at least one terminal   grouping, and mixtures thereof, in the presence of said coating, polymer build-up on the inner surfaces of the reaction vessel is substantially eliminated.          Further, multiple charges or batches of polymer can be made in said internally coated reaction vessel without opening the same between charges thus preventing the escape of unreacted monomer to the atmosphere.

Abstract: Abstract A centerless gear forming tool for cold rolling teeth on a gear blank in which the blank is inserted between a pair of gear forming rolls which are movable toward and away from each other.  The rolls are urged toward each other by a spring, clamping the blank between them and are caused to rotate synchronously in the same direction.  The gear rollers have lugs forming opposing surfaces which engage the blank when the gear rolls are rotated to an initial position.  A latch initially holds the rolls apart so that the blank can be inserted between the rolls and clamped in position by rotating the opposing lugs into engagement with the blank.  The latch is then released causing the blank to be also clamped between the rolls.  Subsequent rotation of the rolls in the direction to move the lugs away from the blank operates to cold form the teeth in the blank under the pressure of the spring.

Abstract: ABSTRACT:         In a ground proximity warning system used by aircraft when unsafe flight configurations defin-ed by specified flight warning mode envelopes are de-tected, alarm generation signals are not immediately, given, instead the continuing flight of the aircraft is monitored by an alarm filtering system which uses independently variable maximum and minimum levels and filtering constants which can be incremented and or decremented as functions of the continuing flight of the aircraft and the warning mode envelopes so as to suppress false or unnecessary alarm generation while generating alarms for dangerous flight configurations.          The filtering parameters may be varied independently for each flight warning mode. In addition audio war-nings are controlled so that warnings once started are completed in the absence of higher priority war-nings, even if they cease to exist, while still existing interrupted lower priority warnings are regenerated when higher priority warnings have been completed.

Abstract: ENGINE TIMING CONTROL CIRCUIT HAVING A SINGLE PICK-UP FOR BOTH STARTING AND RUNNING     ABSTRACT OF THE DISCLOSURE       A single pick-up coupled to sense engine crankshaft position can be utilized for both starting and running Or the engine in an electronic spark timing advance control system.          During starting pulses from the pick-up are coupled via a zero crossing detector to the output ignition stage to cause spark plug firing at an essentially constant firing angle at or just slightly in advance of piston top dead center position During running, the pulses from the pick-up reset, via a reset circuit, an integrator circuit so that a sawtooth waveform representative of engine crankshaft rotational position is developed.  A desired timing signal derived from one or more parameters useful in controlling the time of ignition firing is compared against the sawtooth reference waveform and when a predetermined relationship between the two is attained the ignition is fired.  Should this predetermined relationship not be attained during a cycle of the sawtooth, the reset signal from the reset circuit forces ignition firing.  A frequency sensitive switch circuit senses approximate engine speed to selectively control ignition firing via the zero crossing detector-during starting and via the desired timing signal during running.  A safety feature permits the ignition to continue to fire from the zero crossing detector in the event that firing by the desired timing signal is impaired.

Abstract: POWER BRAKE APPARATUS           ABSTRACT OF THE DISCLOSURE  A power braking apparatus having a housing with a cavity therein through which  a fluid under pressure is continually flowing.  A piston separates the cavity into an inlet chamber and an outlet chamber. The piston has a passageway for connecting the inlet chamber from the outlet chamber.  A valve in the passageway is adapted to regulate the flow of fluid from the inlet chamber to the outlet chamber.  a disc located in the stem of the valve is resiliently biased against a head on the stem.  One side of the disc is connected to the inlet chamber and the other is connected to the outlet chamber.  An actuation input moves the valve toward a seat to restrict the flow of fluid between the inlet chamber and the outlet chamber and establish a pressure differential therebetween.  This pressure differential will move the piston to provide an output force.  When the pressure differential reaches a predetermined value, the resiliently biased disc on the stem will move away from the head to prevent the complete interruption of flow between the inlet chamber and the outlet chamber.

Abstract: ABSTRACT A vanadium emitter cylinder is keyed by a cross-pin to an axially extending connection pin of which one end is seated in the emitter body.  The inner conductor used for the sensor connection is wrapped around the free end of the connection pin, put through a transverse bore in its mid-portion, then bent over in the axial direction of the connection pin and spot welded thereto. The pointed end of the connection pin rests on an insulating spacer through which passes the measuring inner conductor and in which ends another inner conductor used as a compensating conductor.  A tubular outer conductor of the connecting cable comes to an end in abutment against the insulating spacer and is electrically connected with an outer conducting collector shell through an intermediate conducting sleeve fitted on the end of the outer cable conductor. The various pins and conductors, as well as the outer shell, are made of Inconel nickel-chromium alloy.  The helical winding prevents unavoidable thermal stresses from straining the spot welds by which the inner conductor is fastened to the connection pin.

Abstract: ABSTRACT    Most present day CRT alphanumeric displays have a fixed screen layout.  Here additional alternative screen layouts e.g. split screen layout are provided by hardware with operator selection.     A raster scanned CRT display is described having a refresh buffer in which alphanumeric data to be displayed is stored in a first sequence of addresses.  When the refresh buffer is addressed by the first sequence of addresses a first screen layout results.  This will normally be a "full screen" layout.     A translation store (ROS or RAM) provides a modified sequence of translated addresses when addressed by the first sequence of addresses. The refresh buffer is selectively addressed by the modified sequence of translated addresses to display the data in a second screen layout.     Each alternative screen layout requires an associated sequence of translated addresses to determine where the data should be displayed on the screen.  Split screen layout, selectable line length layout, and Hanguel language character layout are described.

Abstract: ABSTRACT OF THE DISCLOSURE       A seismic energy generating assembly includes a seismic energy generator positioned within a cage-like frame and adapted for vertical movement within the frame in re-action to the powerful seismic energy impulses that are trans-mitted downwardly into the earth.  The assembly further includes hydraulic catch cylinders for easing the seismic energy generator back down to the ground within the frame after each impulse is generated.  Horizontal extensions from this frame ride in guides formed by tubular channels for guiding the entire seismic energy generating assembly when lifted up from the ground by hydraulic lifting cylinders so that the assembly can be readily moved from place to place during seismic exploration.  The tubular channels are pivotal-ly mounted to an outer supporting frame on a land vehicle. The seismic energy generating assembly is thereby adapted for swinging movement with the tubular channels about a horizontal pivot axis passing through the assembly and extending trans-versely with respect to the vehicle for accommodating local variations, as encountered, in the slope of the earth's surface.        The horizontal extensions include tough, slip-pery plastic polymer sleeves at least partially surrounding vertical cylindrical mandrels which ride within the tubular channels.  The tubular channels are pivotally mounted through spherical self-aligning bearings, and in this illustrative embodiment the swinging movement is limited to within approximately 10° from the vertical, but this limit may be more or less.
