Abstract: ABSTRACT OF THE DISCLOSURE       Disclosed herein is a plastic fastener which integrally comprises a shank divided into two opposed shank sections connected to each other at their respective lower ends through a hinge portion.  A pair of resilient wings extend from and slant downwardly from the upper ends of the shank sections and a pair of engaging leg members extend from and slant downwardly from the lower ends of the shank section.  Fastening to a given panel having a hole is accomplished by inserting the engaging members of the fastener in a fully converged state through the hole and, upon complete passage of the hinge portion through the entire hole the engaging leg members open into a diverged state thereby causing the divided shank sections to converge and be received in their fully converged state into the hole.  The resilient wings flex against the upper surface of the panel and the engaging leg members remain in a diverged state against the panel and keep the entire fastener from slipping out of the bored hole.

Abstract: Abstract This specification discloses an invention relating to the relationship between a latent image bearing member, such as screen-like photosensitive medium, and a corona discharger used to form a latent image on the latent image bearing member.          A corona discharger is divided into a plurality of dischargers so that, with the sum of the length of the corona discharger for the formation of a latent image and the length of the latent image bearing member is greater than the length, in the direction of movement, of an endless support member supporting the latent image bearing member, the plurality of dischargers may selectively discharge corona in accordance with the rotational position of the latent image bearing member.  By this arrange-ment, the latent image bearing member may be prevented from being dually charged, and the length of the latent image bear-ing member may be minimized to contribute to reduction in size of the image formation apparatus.

Abstract: Abstract of the Disclosure Antimicrobial agents are disclosed containing as the active ingredient a metal complex of a metal ion and a poly-functional organic ligand.  The antimicrobial metal complexes are characterized by a very unexpected aqueous proton induced dis-sociation property which causes the controlled rel??se of toxic metal ion at a p? compatible with microorganism growth.  This dis-sociation property is represented by a sigmoidally shaped curve, i.e., one curved in two different directions like the letter "S", on a cartesian coordinate plot of the negative logarithm (log) of metal ion concentration versus the negative logarithm (log) of hydrogen ion concentration for otherwise known as a pM-pH dia-gram).  Antimicrobial metal complexes are also disclosed which are extremely effective in the controlled release of metal ion from the complex in about the normal range of physiological pH, i.e., about 10-4 to 10-9 moles of hydrogen ion per liter.  The antimicrobial agents act as microbiocides and bacteriostats for microorganisms including, bacteria, fungi and viruses.  Metal complex agents are disclosed which possess excellent stability at high alkaline pH on the order of about 9 to about 12 and, therefore, such agents are very advantageously employed in such media to effect, upon demand, the antimicrobial activity. Aqueous solutions of monocopper(II) citrate complexes have been found particularly effective in the inhibition of microorganism growth or destruction of microorganisms.  Dialkali metal salts of monocopper(II) citrates have been isolated in solid form, such salts possessing extremely high solubility in water or other aqueous media permitting preparation of high concentrations of the monocopper(II) complex for superior biocidal action in aqueous media.

Abstract: METAL ROOF CONSTRUCTION                ABSTRACT OF THE DISCLOSURE         A metal roof construction of the type wherein elongated metal panels are joined together at upstanding vertical side walls by a crimped batten strip.  Shallow step strengthening ribs are positioned closely adjacent to the side walls to strengthen the side walls and prevent buckling and to promote flexure of the panel central portions at the step strengthening ribs under high upward stresses on the panels.  The panels are secured to underlying roof support means through a special clip having a radius of curvature between an upstanding body portion, positioned between side walls of adjacent panels, and a lower flange portion, positioned beneath a panel.  The radius of curvature is sufficient to accommodate the head of a threaded fastener between the clipped lower flange and an overlying panel.  Radius bends are also provided between the clipped body portion and top flanges which overlie inwardly directed flanges on the panel side walls.          Because of the flatness of the panels, conventional caulking can be used between overlying panels and between the panels and the supporting purlins at the eaves and ridges of the roof.

Abstract: ABSTRACT OF THE DISCLOSURE            An ionography imaging chamber wherein the sections of the pressure vessel carry concentric spherical electrodes centered at the source of X-rays and defining a spherical interelectrode gap.          A dielectric receptor sheet is converted into a portion of a hollow cylinder during introduction into the gap and its marginal portions are thereupon biased against one of the sections by an inflatable gasket which seals the gap from the surrounding atmosphere prior to admission of compressed high Z gas.  The admitted gas deforms the sheet against the electrode which is nearer to the source of X-rays while the gas at the rear side of the sheet is allowed to escape by way of ports in the respective section.  If the gap re-ceives two sheets at a time, the admission of high Z gas takes place between the sheets so that each sheet overlies and closely follows the outline of the corresponding electrode.  The two sheets may constitute discrete sheets or overlapping portions of a single sheet which is trained over a roller at a locus remote from the point of introduction of the sheet into the pressure vessel.  Simultaneous exposure of both sheets to object-modulated X-rays results in the making of positive and negative latent images of the object.

Abstract: ABSTRACT OF THE DISCLOSURE         An end-office repeater accepts a high-speed bipolar signal, converts the bipolar signal into a unipolar signal, scrambles the unipolar signal, ant encodes the scrambled unipolar signal into a modified duobinary signal for transmission over a cable pair.  Before cable loss would severely degrade the duobinary  signal, line repeater, and/or inter-office repeaters are installed at predetermined intervals so as to equalize and regenerate the modified duobinary signal.  By so doing, the signal is recovered with acceptable phase jitter, which permits recovery of the original high-speed bipolar signal at the distant end of a repeatered span line.  The receiving-end office repeater equalizes and regenerates the modified duobinary signal, decodes the signal to obtain a unipolar signal, descrambles the unipolar signal, and converts the unipolar signal into a bipolar signal.          Detection of errors in the modified duobinary signal may be obtained without adding redundant digits.  However, errors which may occur during transmission may be lost by the decoding to a unipolar signal. Thus, errors detected from violations of the coding rule of the modified duobinary signal are inserted, by means of an error transfer network, into the bipolar signal and appear ?s violations of the bipolar code.

Abstract: Abstract of the Disclosure The echo path of an echo signal subjected to a time-varying phase shift is bridged by echo cancelling apparatus including a variable phase shifter and an adaptive echo canceller connected in series.  The variable phase shifter includes an adaptive control loop whose operation is compatible with that of an adaptive echo canceller.  The phase-shifter control loop derives a control signal from the output signal synthesized by the echo cancelling apparatus and the residual echo produced by subtracting this output signal from the echo path signal.  The control signal is used to produced a variable phase shift on the signal passing through the variable phase shifter in the echo cancelling apparatus.  The echo canceller adaptively synthesizes a replica of the echo signal produced by the linear dispersive portion of the echo channel, while the variable phase shifter is adapted to impart a time-varying phase shift corresponding to the time-varying phase shift encountered by the echo signal in the echo path.  The echo cancelling apparatus is therefore able to produce an output signal which closely approximates the echo signal including the time-varying phase shift for more effective echo cancellation.

Abstract: SINGLE SIDEBAND TRANSCEIVER             Abstract of the Disclosure A transmitter unit comprises two resonant circuits which are caused to oscillate during transmission to produce two pilot signals of predetermined frequencies.  The pilot signals are mixed with an audio signal and used to modulate a transmission carrier signal in a balanced modulator which forms two sideband signals.  The transmission carrier signal and one of the sideband signals are suppressed to form a single sideband signal which is used to modulate a channel signal for transmission.  A receiver unit comprises a voltage controlled local oscillator which produces a local oscillator signal which is hetrodyned with the modulated channel signal to recover the single sideband signal.  A reception carrier signal is hetrodyned with the single sideband signal in a balanced demodulator to recover the pilot signals and audio signal, the latter of which is fed to a speaker.  The pilot signals are applied to a first frequency detector which detects the differ-ence frequency thereof and triggers a voltage sweep generator to apply a voltage sweep to the local oscillator thereby causing a local oscillator frequency sweep.  The pilot signals are further fed to the resonant circuits which are used during reception as second and third frequency detectors which detect when the hetrodyned pilot signals reach their predetermined frequencies and interrupt the control voltage sweep at that instant, main-taining the local oscillator signal at the proper frequency.          Means are provided to reset the receiver unit to manual local oscillator control if a control voltage sweep is completed without detection of the pilot signals by the second and third frequency detectors.

Abstract: LATERAL CURRENT CONFINEMENT  IN JUNCTION LASERS     Abstract of the Disclosure Described is a stripe geometry double hetero-structure (DH) junction laser in which lateral current confinement is achieved by pairs of laterally spaced, reverse-biased p-n junctions.  A mesa is formed on an n-GaAs substrate, for example, and a layer of p-AlGaAs is then grown by LPE so that nucleation does not occur on the top of the mesa.  Laterally spaced zones of p-AlGaAs are thus formed on either side of the mesa.  An n-p-p or n-n-p DH is then grown so that the interface between the p-AlGaAs layers and the first n-layer of the DH forms a pair of laterally spaced p-n junctions separated by the mesa.  When the light-emitting p-n junction in the DH active region is forward biased, the pair of spaced junctions are reverse biased so that pumping current is constrained to flow through the active region in a narrow channel to the mesa.  Further lateral current confinement is achieved by forming on the upper DH surface a second pair of reverse biased p-n junctions separated by a window in alignment with the mesa.
