Abstract: ABSTRACT OF THE DISCLOSURE           A television receiver has a tuner, an intermediate frequency amplifier, and a detector for recovering a composite signal including horizontal and vertical display synchronization components and picture information.  Horizontal display means produce a long-duration trace signal and short-duration retrace signal and a coincidence gated AGC system which is responsive to coincidence of the horizontal retrace signal and horizontal synchronization signal controls the gain of the intermediate frequency amplifier.  A combination synchronizing signal separation and AGC lock-out defeat circuit comprises a transis-tor, having an input electrode DC coupled to the detector, a common electrode coupled to a charge-discharge circuit such that the input-to-common electrode junction of the transistor and the charge-discharge circuit cooperate to establish a bias voltage dependent upon the occurrence and amplitude of the display synchronization signals, and an output electrode DC coupled to the AGC system.  An override system response to said bias means overcomes the coincidence requirement of the AGC system to render said AGC operative solely in response to the occurrence of horizontal retrace signals when the bias indicates prolonged absence of sync pulse signals.

Abstract: APPARATUS AND METHOD FOR THERMAL TREATMENT        OF ORGANIC CARBONACEOUS MATERIALS        Abstract of the Disclosure An apparatus and method for performing a continuous thermal treatment of organic carbonaceous materials under con-trolled pressure in which the feed material is introduced into the system in the form of a slurry, and the level of liquid is maintained at a preselected operating level, serving as a gas-tight seal.  The feed material is conveyed upwardly of the liquid operating level and is thereafter introduced into a re-action chamber in which it is heated to within a controlled elevated temperature range under controlled pressure in a manner to effect vaporization of at least a portion of the volatile substances therein, forming a gaseous phase composed of condensible and noncondensible vapors.  The gaseous phase is withdrawn from the reaction chamber in a direction counter-current to the travel of the feed material and in heat exchange relationship therewith, effecting condensation of the condens-ible phase and transport of the noncondensible phase, and is extracted from the system through a discharge port disposed above the liquid operating level.  The thermally reacted pro-duct is cooled and transferred from the reaction chamber into a receiving chamber from which it is extracted continuously or intermittently.

Abstract: METHOD OF DETECTING LEAKAGE OF                    NUCLEAR REACTOR COOLANT     ABSTRACT OF THE DISCLOSURE     A method of detecting leakage of cooling water in a water-cooled nuclear reactor.  An acoustic-electric converter element is mounted on a wall of a member constituting a pres-sure boundary of a cooling system or on an attachment of the wall.  Acoustic vibrations caused by leakage of the cooling water is detected and converted into electric signals by means of the acoustic-electric converter element.  The elec-tric signals of a frequency of 0.1 to 1 MHz are selected.          When the thus selected electric signals have reached a pre-determined level higher than a background noise level, an alarm is produced to inform the leakage of the cooling water.

Abstract: CONTAINER                      ABSTRACT       A container having a tray portion and a cover sealed to the peripheral top edges of the tray. Cut score lines on the inner side of the cover provide a splitting of the paper-board of the cover upon opening to allow the cover to be peeled from the tray to a hinge at the back edge of the tray. offset double cut score lines may be provided on the upper and lower sides of the cover at the front edge of the tray, which will split upon opening of the cover to yield overlapping locking f laps which can be used to reclose the cover. Flanges may be attached to the lateral side edges of a paperboard tray by cut score hinges, and adhered to the inner side of the cover to provide layer separation of the flanges upon opening rather than layer separation of the cover. Alternatively, double cut score lines can be formed along the lateral sides of the cover in position to register with lateral side flanges on the tray, which split and provide overlapping locking flaps when the cover is opened. The cover can then be completely removed from the tray upon opening, and is reclosed by inserting the locking flaps on the removed portion of the cover under the locking flaps projecting from the tray.

Abstract: ABSTRACT OF THE DISCLOSURE     A removable closure for a pressure container having an opening with a peripheral bead into which there is inserted a threaded neck member, the neck member being formed of a resil-ient plastic material adapted to expand and contract and having an interlocking engagement with the bead.  The neck is provided with a radially extending handle portion by means of which the container is adapted to be carried and which also serves to prevent rotation of the neck member upon the applica-tion and threading of a cap to the neck member, the cap having a plug portion which enters into the opening in the neck member and being tapered wedges into the neck member and spreads the portion of the neck member which is in radial alignment with the bead portion, thus tightly forcing such portion against the bead to provide a high pressure seal. The plug portion is provided with pressure relief grooves at its inner end extending axially of the plus such that as the cap is being unscrewed from the neck portion, the grooves are positioned to communicate the interior of the container with a space between the interior of the neck and the plug outwardly of the interlocking portion so that the excess pressure can bleed off to the atmosphere about the threads.  The invention also comprises novel pilfer-proof mechanism which has to be broken away from the cap in order to unscrew the cap and there-fore readily is indicative of tampering.

Abstract: Abstract of the Disclosure A pocket size dose rate monitor is disclosed which is meterless, small and rugged   The instrument is cylindrically shaped so as to be carried, for example, in the shirt pocket of a user.  A battery powered blocking oscillator drives a Geiger-Mueller ionization chamber which is series connected to a potentiometer whose movable slider contact is asso-ciated with an indicator scale which is calibrated, for example, in dose rate   The slider contact is also electrically coupled to a circuit which is adapted to control the energization of a miniature electric lamp or other type of light source such as a light emitting diode.  For a measuring or monitoring dose rate, the user manipulates an actuator element which varies a control voltage selected from the voltage appearing across a calibrated potentiometer for controlling the operation of the control circuit. Since the voltage across the potentiometer varies in proportion to the dose rate due to the effect of the ionization chamber, the light source will be energized when a certain dose rate is detected.
