Abstract: Abstract:    A chroma signal gain control circuit is constructed to include a first band pass amplifier, a second band pass amplifier, a burst gate circuit, a switch circuit and an ACC detecting circuit.  The output signal of the first band pass amplifier is fed to the input of the second band pass amplifier, the output signal of which is fed to the input of the burst gate circuit.  The switch circuit selectively transmits either the output of the burst gate circuitry or the output of the second band pass amplifier to the ACC detecting circuit.  The gain of the first band pass amplifier is controlled by feeding the detected output of the ACC detecting circuit to the first band pass amplifier.  In order to prevent saturation when the level ratio (C/B) between the color burst signal and the chroma signal exceeds a predetermined value, the switch circuit transmits the output of the second band pass amplifier to the ACC detecting circuit.

Abstract: ICE AGGREGATE ROAD AND METHOD AND  APPARATUS FOR CONSTRUCTING SAME     ABSTRACT OF THE DISCLOSURE   A method and apparatus for constructing an ice aggregate structure, such as a road, at all sub-freezing temperatures likely to be encountered at high latitudes, including below -45°F.   Initially, ice is mined, crushed and then stripped of substantially all "fines", i.e., ice particles smaller than approximately 0.1 inch.  The resulting crushed ice aggregate is then distributed and placed to the desired grade without requiring surface work or compaction.  The upper thickness of the crushed ice aggregate is then bonded by spraying heated water thereon during single or multiple passes.  Apparatus is provided to prevent evaporative cooling of the spray water prior to its contact with the crushed ice surface, which pre-ferably comprises an enclosure or flexible skirt which extends around the spray nozzles downwardly to the ice aggregate surface.  Substantially immediately following the final spray pass, normal wheeled traffic, such as machines utilized to form the ice aggregate road and to transport crushed ice and bond water, can be permitted to traverse the bonded crushed ice aggregate.   A preferred embodiment of a crushed ice placement and bonding machine is disclosed which permits a smooth ice aggre-gate surface to be constructed over uneven terrain.  The machine is capable of changing grade as may be required to ramp-on or ramp-off a structure or to clear a natural obstruc-tion, and includes means for incorporating super-elevation (banking) into road curves.  The machine is totally self-contained and self-sufficient, and permits construction, on a continuous flow basis, of roads and other civil structures over natural terrain without any machinery contact with the terrain.  That is, the machine is capable of operating from the surface that it constructs.     ABSTRACT     The construction of roads and other such structures of gradated ice aggregate manufactured by crushing ice has been investigated by both laboratory and scale field testing.  This report contains the results of a field test conducted in Fairbanks, Alaska during the period of February 22 - March 8, 1977.     The results indicate that roads constructed of ice aggregate compare favorably in performance with those constructed of snow.     Field experience has shown that ice aggregate roads can be constructed faster with lower equipment and manpower requirements than similar saturated snow structures.     The concept of in situ crushing of ice on the surface of frozen streams and lakes has been explored and found promising.     Damage to fragile ecosystems may be greatly reduced by using single pass thick section ice aggregate construction techniques.     (3)

Abstract: METHOD AND TITLE:  APPARATUS FOR SETTING AND ORIENTING A              WHIPSTOCK IN A WELL CONDUIT                         ABSTRACT OF THE INVENTION    The invention provides an improved method and apparatus for effecting the setting of a whipstock in a desired angularly oriented position in a well conduit solely by the use of a wire Line but can be set on tubing or drill pipe, if desired.  A packer is provided which can be expanded into sealed engagement with the casing at a desired location.  The packer is provided with a key element, either a key or a key slot, and orienting elements by which a conventional well bore survey can provide an accurate indication of the angular alignment of the anchor key element.  A whipstock anchor is provided incorporating a socket portion in which the whipstock may be rigidly secured and a shaft portion which is insertable within the bore of the packer and has key element cooperating with the keyway,  or key  provided in the packer.  After setting of the packer in the well conduit  a survey is made to provide an accurate indication of the angular position of the packer keyway or key.  The whipstock is assembled n the whipstock anchor socket and the socket is rotated relative to the shaft portion so that the arcuate face of the whipstock is positioned at a desired angular displacement from the angular position of the key element in the whipstock shaft utilizing a com-pass.  The whipstock shaft is then rigidly secured to the whipstock socket and the complete assembly is lowered into the well on drill pipe, or the like, and secured in the packer.

Abstract: PROCESS FOR CHLORINATION OF PVC IN WATER     WITHOUT USE OF SWELLING AGENTS                  ABSTRACT OF THE DISCLOSURE A process is disclosed which permits the photochlorination of poly(vinyl chloride) resin ("PVC"), in an aqueous medium without the use of swelling agents such as are conventionally used. The chlorination reaction proceeds in an aqueous suspension having a high PVC concentration, yet allows the production of essentially uniformly chlorinated poly(vinyl chloride) resin ("CPVC") of excellent quality and uniformity, with a heat distortion temperature ("HDT") of at least 100°C. The transfer of chlorine from the gaseous phase into the aqueous phase, and thence into the solid PVC phase, has been accelerated by this process which provides a critical combination of photo-illumination, elevated temperature and elevated pressure in a reactor devoid of oxygen and a swelling agent for the PVC. The "water-chlorination process" of this invention preferably prov-ides a "soak" period, after removal of oxygen from the aqueous PVC suspension, at a soak temperature of about 60°C to about 75°C, from which the temperature may either be (a) autogenously "ramped" during photochlor-ination under pressure to a finishing temperature in the range from about 80°C to about 120°C, or (b) be raised to a temperature above 65°C prior to photochlorination under pressure, and maintained substantially constant at this finishing temperature. Whether the reaction is "ramped" or isothermal, the suspension is exposed to an appropriate level of substantially constant ultraviolet light radiation, and the reactor pressure is maintained substantial-ly constant in the range from about 25 psig to about 100 psig. Chlorination of a PVC starting material having a porosity in the range from about 0.1 cc/g to about 0.7 cc/g and a surface area in the range from about 0.7 m2/g to about 3 m2/g proceeds at a rapid rate.
