Abstract: CO-CRYSTALLINE ORGANIC PHOTOCONDUCTORS AND     HETEROGENEOUS COMPOSITIONS THEREOF     Abstract of the Disclosure Co-crystalline organic photoconductors comprising p-terphenyl doped with p-quaterphenyl are described.  The co-crystalline photoconductors defined have characteristi-cally greater (112) x-ray diffraction peak widths measured at half-maximum intensity compared to undoped p-terphenyl controls.  Such photoconductors can be produced by forming a solution of p-terphenyl and p-quaterphenyl photoconductors in a common solvent and co-crystallizing the photoconductors therefrom.  Heterogeneous photoconductive insulating compositions comprising a dispersion of these co-crystalline photoconductors in an electrically insulating binder can be applied to an electrically conducting support to provide an electrophotographic element with enhanced photoconductive speed.

Abstract: Abstract of the Disclosure Apparatus for forming an improved joint when utilizing friction-fusion process by positioning overlapping portions of a thermoplastic strap between a pair of welding jaws having complementary opposing strap gripping surfaces.  The strap gripping surface of one of the jaws includes a protrusion at an end thereof disposed perpendicularly to the strap length. The one jaw is moved perpendicular toward the other jaw so that the protrusion initially engages the adjacent overlapping strap portion prior to engagement by the remainder of the strap gripping surface, whereby the facing surfaces of the overlapping strap portions in alignment with the protrusion are compressed into heat generating frictional engagement with one another and the remaining overlapping strap portions between the jaws are gripped by adjacent gripping surfaces.  The jaw opposite to the jaw with the protrusion is then moved in a direction generally parallel to the strap gripping surfaces while the overlapping strap portions in alignment with the protrusion are compressed to initiate interface melting between the compressed surfaces.  During this time, movement of the jaws toward one another is continued to compress the remaining overlapping strap portions between the jaws into heat generating frictional engagement while the generally parallel movement of the one jaw is continued to expand interface melting to the facing surfaces of the remaining overlapping strap portions between the jaws.

Abstract: Abstract of the Disclosure A strip of fasteners such as pierce nuts is formed from a metal blank with no scrap resulting from the provision of spacing between adjacent nut bodies, and without the difficulty and expense incident to attaching nut bodies to connecting elements.  The body portion of a laterally flanged blank is served in the transverse direction to separate nut bodies from the blank without fracturing the flanges.  The flanges are served in the longitudinal direction to form served longitudinally extending flange segments integral at both ends with unsevered flange segments.  When the flanges are straightened, the stretching of the severed flange segments resulting from shearing provides a spacing between adjacent nut bodies in the strip.  The strip includes spaced apart nut bodies interconnected by continuous lateral flanges.  The flanges include unsevered lateral flange segments integral with both sides of each nut body, and severed flange segments integral at both ends with the unsevered flange segments. Elongation of the severed flange segments provides spacing between adjacent nut bodies.

Abstract: Abstract of the Disclosure There is disclosed a noise reduction system for improving the signal-to-noise ratio of a color television video signal by utilizing an inter-frame correlation of such signals.  Such  systems prevent the formation of an afterimage or lag that could otherwise result from such a correlation when a fast moving object is being shown and the known systems use variable attenuators which must have plural sets of transmission factors, introducing a degree of complexity which the invention seeks to overcome.  In this invention, a video signal is stored for a period of time equal to the period of one television frame, producing a stored signal.  Motion between the stored signal and the subsequent video signal is detected and there is pro-duced as a result a frame-to-frame difference signal to which is further introduced a non-linear transmission-factor.  This factor is dependent upon the level of the frame-to-frame difference signal.  The frame-to-frame differ-ence signal, as varied by the non-linear transmission-factor, is added to the subsequent video signal with the result of an improvement in the signal-to noise ratio of that signal.

Abstract: STRUCTURAL FAILURE DETECTION METHOD               Abstract of the Disclosure Crack initiation in metallic structural members subject to cyclic loading is predicted by sensing metal-lurgical changes taking place as a result of the cyclic loading.  Fatigue loading produces a cycle comprising a con-dition described as fatigue relaxation followed by fatigue intensification.  By monitoring this cycle, measured strain for a known applied load will increase or decrease.  By monitoring the change in strain load, crack initiation can be predicted as fatigue relaxation becomes fatigue intensi-fication.  In a preferred embodiment, the strain gauge is mounted beneath a patch excluding ambient atmosphere during monitoring of the structural members.
