Abstract: ABSTRACT OF THE DISCLOSURE      In an anchoring assembly which is secured in a borehole in a receiving material by a hardenable adhesive material, the assembly includes an anchoring member and a guide ring through which the member is driven into the borehole.  One of the anchoring member and guide ring is provided with a helically shaped projection while the other has a helically shaped groove formed in it for interengagement with the projection.  As axial force is imparted to the anchoring member and it is driven through the guide ring into the borehole, the interengagement of the helically shaped projection and grooves causes the anchoring member to rotate as well as to move axially.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus are disclosed for producing photographic reproductions of line and continuous tone graphic materials.  The invention is useful in the newspaper field for opto-electrically producing plate-ready negatives or plates them-selves from line and continuous tone copy.  The line and continuous tone graphic materials are scanned incrementally to produce high resolution signals representative of the gray levels of incremental areas of both the line and continuous tone materials.  A plurality of the high resolution signals representing the gray levels of the incremental areas of the scanned continuous tone material are combined to produce low resolution signals representing the gray levels of larger, low resolution incremental areas of the scanned continuous tone graphic material.  The high and low resolution signals are employed to control an incremental, scan exposure of a photosensitive member. The photosensitive member receives an exposure that is a function of the gray levels of the high resolution incremental areas of the line graphic material and of the gray levels of the low resolution incremental areas of the continuous tone graphic material.  Significant reductions in data processing capacity are achieved by processing the continuous ton gray level information in a low resolution format.   1.

Abstract: S P E C I F I C A T I O N                  ERROR CORRECTION SYSTEM FOR RANDOM                          ACCESS MEMORY      ABSTRACT OF THE DISCLOSURE            An error correction system is provided for a random access memory system of the magnetic core or plated wire type, and which serves to render the memory system immune to the effects of nuclear radiation, and the like.  The system of the invention in-cludes circumvent circuitry which serves to limit all currents in the memory access network to safe values during a radiation event, so as to prevent burn-out of the memory and of its associated components.  The system of the invention also serves to correct single word errors which can occur to words being written or read during the radiation pulse.  The single word error correction is achieved in a first embodiment of the invention by partitioning the fixed data program words in the memory into blocks; by provid-ing an error correction word for each such block, and by recon-structing from the error correction word, the word being read or written during the radiation pulse.  This is achieved in the first embodiment of the error correction system by first accessing the affected word, then loading all zeros into the memory address of the affected word, and then reconstructing the effected word by the provision of an "exclusive or" summing means which forms a computed error correction word for the entire block, including the affected word (which is now zeros), plus the original error correc-tion word.  The computed error correction word is a reconstruction of the affected data word.  A second embodiment of the invention achieves the same correction in the case of the variable data storage portion of the memory, by means of a system which con-tinuously up-dates the error correction word as the variable data in the memory is up-dated. Further embodiments of the invention provide error correction to the variable data words without the use of error correction words.

Abstract: AUTOMATIC NOISE LIMITER     ABSTRACT    The output from a peak detector of a conventional radio receiver includes a recovered audio signal and a DC level.          The disclosed noise limiter processes the detector output through both low pass and high pass filters.  The low pass filter produces a DC signal representative of both the detector DC level and the recovered audio signal level.  The high pass filter passes only the recovered audio signal.  A semiconductor diode connects between the filter outputs, and the output of the noise limiter.  For peak detector levels at, or below the 100% modulation level the diode is forward biased and passes the audio signal to the noise limiter output for further receiver processing.  Peak detector levels exceeding 100% modulation, such as noise, reverse bias the diode whereby the audio signal is blocked from subsequent receiver stages.

Abstract: RCA 69,154 UHF TUNING CIRCUIT UTILIZING A VARACTOR DIODE                 Abstract of the Disclosure In the UHF tuning portion of a television receiver, a varactor tuned circuit is coupled to the gate electrode of a field effect transistor (FET) through an impedance trans-formation network comprising a series connected capacitor and shunt connected inductor.  In order to increase the signal power transferred between the tuned circuit and the FET at the lower end of the UHF range, the values of the capacitor and inductor are selected so that the relatively low value of equivalent parallel impedance exhibited by the tuned circuit at the lower end of the UHF range is impedance transformed to a value approximately equal to the value of the impedance exhibited at the gate of the FET. A second impedance transformation network, similar to the first, is coupled between the drain of the FET and a second varactor tuned circuit to further increase the signal power transferred between the FET and the second tuned circuit at the lower end of the UHF band.  the values of the capacitor and inductor comprising the impedance transformation networks are also selected so that the signal power gain of the UHF tuning portion at the upper end of the UHF range is not substantially degraded.  Because of the impedance trans-formation networks, resonant points below the lowest frequency in the UHF band are established.
