Abstract: CORONA CHARGING DEVICE            Abstract of the Disclosure A negatively biased corona discharge system includes a conductive electrode having a thin inorganic dielectric outer layer bonded thereto which is employed as a corona discharge electrode.  The discharge system is utilized for uniformly placing a negative charge on an insulator substrate such as an electrophotographic imaging surface.          The coating on the electrode acts to suppress the widely spaced emission nodes common to all negatively biased metal corona discharge electrodes.  The coated electrode may, therefore, be placed in close proximity to the substrate which it is charging and operated at low emission densities without sacrificing charge uniformity thereby reducing the power requirement of the corona discharge system.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus for transmitting intelligence over a carrier wave are disclosed in which a signal wave is combined with a carrier wave to produce a composite wave having a recognizable pattern of variations in intervals that are defined by preselected locations in the composite wave.  The pattern of variations in intervals resulting from the combination of the signal wave with the carrier wave represents at least a portion of the intelligence to be transmitted over the carrier wave.  The intelligence is extracted from the composite  wave for subsequent utilization.  In the preferred embodiment the intelligence is transmitted over an electric power distribution network utilizing the alternating wave thereon  as the carrier wave.  The variations in intervals defined by the preselected locations in the wave are detected and the detected interval variations are converted into a signal which has a characteristic that is a function of the recognizable pattern of interval variations.

Abstract: Abstract of the Disclosure A resilient plug for closing and sealing the opening formed in a concrete wall by the removal of the tie rod used to support the walls forms.  The elastic plug is formed with a tapered socket and has a smooth outer surface, including a tapered leading end and a main body section, having a larger diameter than the hole in the concrete and extending from the leading end.  The plug is engaged in a tie rod hole by inserting a rod into the socket and pushing the plug into the tie rod hole.  This causes an elongation of the plug, reducing its diameter and facilitating its insertion into the tie rod hole.  However, when the force applied to the plug during insertion is removed the plug expands radially, forming a tight seal with the wall of the tie rod hole.

Abstract: Abstract of the Disclosure The herein proposed device is intended for building up high pulse liquid pressures. It may find suitable application in mining industry and can be advantageously used in construc-tions of hydro-power installations. The device comprises a cylinder accommodating a two-step piston having an accelera-ting actuator. The piston step of smaller diameter is posi-tioned, during the piston stroke, within a high-pressure cham-ber communicating with a liquid supply source and fitted with an opening for the liquid discharge. The piston step of smal-ler diameter is provided with a rod having a widening at the free end thereof, while the high-pressure chamber has a con-stricted portion passing into a widening towards the opening for the liquid discharge. At the initial stage of the piston stroke, the widening of the rod overlaps the constricted por-tion of the chamber to lock the liquid within the chamber bet ween the constricted portion thereof and the piston step of smaller diameter, whereby high pressure of this particular liquid is built up. As the piston continuous to move in the space between the rod and the widenings of the high-pressure chamber, a channel with an annular cross-section is formed.         This channel serves to communicate the high-pressure chamber with the opening for the liquid discharge. The proposed devi-ce makes it possible to substantially increase the jet force of the discharged liquid and enhance the factor of utiliza-tion of energy derived from the piston acceleration.

Abstract: Abstract of the Disclosure A system and method are disclosed for controlling text storage in a text processing system using a segmented, serial bulk storage device.  A plurality of storage segments of equal length are further subdivided into portions of equal length.  A typical page of text occupies more than one portion of a segment.  During system operation a log or directory is built and written, in updated form, onto a portion of the storage after any text data is written onto 'he storage.  To minimize the time in accessing the pre-determined portion on which the log is stored and to minimize wear of the electromechanical accessing components, portions of more than one segment are dedicated for storage of the log and the segment nearest that on which the text data is written is utilized for storage of the updated log.  The beginning of the log includes an activity count indicative of the number of text storage operations that has taken place.  The most current log is found by seeking the highest activity count.  In addition to providing information relative to segments and portions on which text is stored, the log includes other characteristics to distinguish utilized portions and unused-available portions from portions that are not to be used because of hard errors thereon.          Since date is read from the storage and recorded onto the storage by portions, provisions are made for writing into the memory, a number of error codes equal to the number of bytes in a portion when read errors occur in reading from the storage and during relocation for recording a number of error-codes equal to a portion  when the text data cannot be successfully read from the storage.  Thus, the appropriate storage size is maintained for rekeying  the text.
