Abstract: A ferrule is used together with other components to couple a liquid tight fitting to flexible metal conduit. To assure secure coupling, the ferrule must be fully engaged with the flexible metal conduit.  Full engagement of the ferrule is not always obtained because of carelessness, burrs, tightness or other obstructions.  Even if full engagement is achieved, it is not always maintained as other parts of the fitting are assembled.  The improved ferrule includes a hole which provides means for visually inspecting the engagement of the ferrule with the flexible metal conduit even after the fitting is fully assembled. The ferrule may or may not  include an outer cylindrical wall for enclosing a portion of the end of the flexible metal conduit.

Abstract: ABSTRACT:            Cross-correlation arrangement for determining the presence or absence of a signal x2(t) of known frequency in an unknown signal x1(t) if this signal x2(t) is present for at least a period of time ?o with an unknown starting instant. An auxiliary signal a1(t) is added to the signal x2(t). The sum signal is converted into one-bit code words s(nT) which are multiplied in at least a first correlation channel by one-bit code words yper(kT) which are stored in a storage medium having at least N/2 addressable storage locations. The code words yper(kT) are elements of a series {yper(kT)}  which is formed by the code words which occur in a predetermined time interval having a length NT and which are of a non-periodical signal of the form sign [x2(t) + a2(t)]. The product code words obtained are added together in an integrator. This integrator is read each time after a time interval NT and reset. The absolute value of an output code word of the integrator is optionally added to corres-ponding code words of other correlation channels. The sum code words obtained in this way are integrated in a second integrator whose contents is continuously compared with a detection level. If No =  ?o/T, N is smaller than No for example a factor of 3. The value of N determines the width of the detection characteris-tic.

Abstract: SPECTROPHOTOMETER FOR DUAL MODE      FLUORESCENCE ANALYSIS Abstract of the Disclosure A sprectrophotometer includes a wide band radiant energy source and a detector for providing an output signal proportional to the intensity of the radiant energy received thereby.  A light pipe system is divided into a reference path and a sample path.  Such system coacts with a rotary assembly having a variable monochromatic filter located diametrically opposite to an opening through which radiant energy can freely pass.  The remaining portions of the rotary assembly are opaque so that as the assembly turns, the sample and reference paths are serially energized by monochromatic energy and then by polychoromatic energy. The sample path includes a sample illumination and collection system for illuminating a test sample and collecting the light reflected therefrom.  The resultant output of the detector can be analyzed to determine the amount of fluorescence.

Abstract: STRUCTURE ADAPTED TO BE          SUCCESSIVELY DRAWN AND TELESCOPED     ABSTRACT OF THE DISCLOSURE         A structure comprising a plurality of partition members all of substantially the same size and configuration and each made from sheet material and each providing a pair of spaced opposite partition faces connected at one side and non-connected at the other side, each partition member having the spacing between its opposed faces increasing gradually from its joined edges toward its unconnected edges and joined sides of a pair of adjoining members having a predetermined distance from each other. These partition members are grouped into a telescoped assembly by guiding each of them into the internal space of another when not in use.  When in use, the partition members are successively drawn from the telescoped assembly to provide continuous partition faces of a partition between two compartments of a room, sliding door or a window shutter.          The invention thus provides a novel structure which does not occupy a large space when not in use, which can be easily handled, can exhibit an improved sound insulation effect when used as a partition between two compartments of a room, and can be easily manufactured due to a simple construction.

Abstract: ABSTRACT OF THE DISCLOSURE: a honing tool having a mandrel with longitudinal grooves each of which has an inclined bottom slidably engaged by a correspondingly wedge-shaped honing stone.  The honing stones partially project through windows in a sleeve and by these windows are held stationary in their longitudinal direction while being able to move radially with regard to the sleeve when the mandrel moves in either longitudinal direction,  The longitudinal adjustment of the mandrel relative to the sleeve is effected by a spindle which threadedly the mandrel in its axial direction and is rotatable by hand in either direction to thereby either move the spindle in one or the other longitudinal direction.  In response to such longitudi-nal movement of the mandrel, the honing stones are adjusted radially either outwardly or inwardly, to increase or de-crease the honing diameter.       The mandrel is under continuous  pressure by a spring in the sleeve with this pressure acting in one of its axial directions to thereby urge the mandrel to axially move in one or the other direction while simultaneously exerting a radial uniform pressure and when possible radial movement of the honing stones to thereby maintain the honing pressure exerted upon the wall of the bore to be honed.
