Abstract: GRAPHIC SYMBOL GENERATOR                 ABSTRACT OF THE DISCLOSURE            Apparatus for generating graphic symbols on a cathode-ray tube employs a beam control system which starts each of a plurality of parallel strokes required for each symbol at the bottom, using a programmed offset for symbols which extend below a baseline, and to otherwise move a symbol in the X and Y axes from a position routinely specified as spaced symbols are displayed in a line.  The slope of the strokes for a symbol is controlled for italicizing the symbols by programming the relative magnitudes and signs of inputs to X and Y integrators which generate ramp signals added to symbol positioning signals.  The beam is turned on and off during each stroke in response to a programmed and clocked bit stream of coded digital signals.  The size of a symbol is controlled by programming the clock rate for the beam on-off control and the magnitudes of the inputs to the X and Y integrators.

Abstract: OPTICAL FIBER FABRICATION AND RESULTING PRODUCT            ABSTRACT OF THE DISCLOSURE            A preform for fabrication of a glass fiber optical transmission line is prepared by chemical reaction of vapor ingredients within a glass tube. Reaction, which may be between chlorides or hydrides of, for example, silicon and germanium with oxygen, occurs preferentially within a constantly traversing hot zone. Flow rates and temperature are sufficient to result in glass formation in the form of particulate matter on the inner surface of the tube. This particulate matter deposits on the tube and is fused with each passage of the hot zone.  Continuous rotation of the tube during processing permits attainment of higher tempertures within the heated zone without distortion of the tube.                             - i -

Abstract: Abstract of the Disclosure A pontoon system for supporting watercraft on a body of water having a submersible structure comprised of pontoons into which air is injected expelling the water therefrom to provide lift for the system and a frame which maintains the pontoons in fixed spaced relationship. The frame includes support pads which extend upwardly therefrom and which contact the hull and keel of the watercraft for support purposes. The pontoons are divided into chambers by bulkheads which allow the water to be forced from the front portion of the pontoons first. Thus the front of the watercraft is lifted initially which stabilizes the watercraft and the pontoon system before the usually heavier aft portion of the watercraft is lifted; this reduces the possibility that the watercraft will become unstable during the lifting process. Air may be released from said pontoons for lowering the pon-toon system into the water. A safety system is provided to lower the system into the water if a leak develops.

Abstract: ABSTRACT OF THE DISCLOSURE      A centrifugal clutch construction having an outer driven member and an inner driving rotor assembly.  The rotor assembly has a pair of spaced, radially extending, side plates mounted in fixed positions on a driving shaft, and a core fixed to the shaft between the side plates.  The core is provided with diametrically opposite surfaces engaging and supporting associated pairs of clutch shoes when the shoes are in retracted position.  A release plate is slidable mounted between each pair of clutch shoes, and the release plates and clutch shoes are retained in retracted position on the core by pairs of clamping balls.  The balls are located mainly within holes formed in each pair of clutch shoes and portions of the balls project partially into openings formed in the side plates.  Each pair of balls frictionally clamps a release plate therebetween when the clutch is in disengaged posi-tion.  The release plates move radially outwardly under the influence of centrifugal force and overcome the clamping and friction forces of the retaining balls when the shaft reaches a predetermined speed.  The balls then move laterally of the side plates inwardly toward each other into U-shaped slots formed in the release plates and out of engagement with the side plates, whereupon the clutch shoes snap into engagement with the outer driven member.
