Abstract: Abstract of the Disclosure A liquid such as an aqueous or non aqueous photo-graphic solution or dispersion, for example an aqueous gelatin-silver halide emulsion, is debubbled by flowing a stream into, through and out of a debubbling chamber while maintaining a pool in the  chamber.  Ultrasonic vibrations are transmitted to the pool by energizing an ultrasonic horn positioned within the pool, and a vacuum is pulled on the chamber to assist gas disengagement and removal.  In one modification the metering liquid flows down the interior walls of the chamber as a thin film which is subjected to ultrasonic vibration by external transducers.  The apparatus comprises a closed container, an ultrasonic horn projecting up form the bottom in position to be immersed in the pool, and vacuum forming means connected to the container above the surface of the liquid pool.  The horn's free end surface can be smooth, or can have projections or holes for energy concentration.  The horn can have one, two or more antinodes within the container, and can have lateral projections at any antinode other than at the end.  Means are provided for sensing the pool level and controlling the inflow of liquid to hold the level constant.

Abstract: A reference signal contained in the vertical blanking interval of the transmitted television signal is used in the color television receiver for automatic hue and saturation control.  This vertical interval reference (VIR) signal includes a chrominance reference portion and a black level reference portion.  The chrominance reference portion contains hue indicative information in that one of the color difference signals is zero and saturation indicative information in that one of the color signals is zero.  The receiver is responsive to the VIR signal once during the black level reference portion to establish a zero reference for the hue control circuit and for the saturation control circuit.  The receiver is responsive to the VIR signal a second time during the chrominancs reference portion to set proper hue and saturation by automatically reducing to zero any differences between the indication of hue and saturation obtained from the VIR chrominance reference portion and the established zero references.

Abstract: ABSTRACT OF THE DISCLOSURE          A method for emplacing a production casing such as a pipeline or other conduit beneath a surface obstacle such as a water course is disclosed.  A drill is provided which has a trailing drill string.  A pilot hole is drilled along an inverted arcuate path beneath a surface obstacle from one side to the other side of the obstacle so that the drill string occupies and pilot hole.  A reamer is provided which has a relatively smaller leading end and a larger trailing end.  The leading end of the reamer is attached to one of the ends of the drill string, and an end of the production casing is attached to the trailing end of the reamer.  The production casing is thrust into the pilot hole at one side of the surface obstacle to project the reamer with the production casing following into the pilot hole.  As the production casing is thrust into the pilot hole at one side of the obstacle, the drill string exits the pilot hole at the opposite side of the obstacle.  The reamer is operated by rotating the production casing or other method simultaneously with thrusting the production casing into the pilot hole to scarify and dislodge the earth circum-scribing the pilot hole.  The pilot hole is enlarged to a diameter slightly greater than the production casing to provide an annulus between the production casing and the reamed hole.  Drilling mud is injected through the drill string to exit at the reamer where it entrains the dislodged earth.  The drilling mud containing the dislodge earth is allowed to flow into the annulus surrounding the production casing.

Abstract: NUCLEAR REACTOR APPARATUS                 ABSTRACT OF THE DISCLOSURE      The reactor and its containment, instead of being supported on a solid concrete pads, are supported on a truss formed of upper and lower reinforced horizontal plates and vertical walls integrated into a rigid structure.  The plates and walls form chambers within which the auxiliary components of the reactor, such as valves, pumping equipment and various tanks, are disposed.  Certain of the chambers are also access passages for personnel, pipe chases, valve chambers and the like.  In particular the truss includes an annular chamber.      This chamber is lined and sealed by a corrosion-resistant liner and contains coolant and serves as a refueling cooling storage tank.  This tank is directly below the primary-coolant conductor loops which extend from the reactor above the upper plate.  The upper plate includes a sump connected to the tank through which coolant flows into the tank in the event of the occurrence of a loss-of-coolant accident.  The truss extends beyond the containment and has chambers in the extending annulus.  Pumps for circulating the coolant between the refueling coolant storage tank and the reactor are provided in certain of these chambers.  The pumps are connected to the reactor by relatively short coolant con-ductors.  Access to these pumps is readily afforded through hatches in the extending annulus.
