Abstract: METHOD AND APPARATUS FOR IN-DUCTIVELY HEATING THE END OF     AN ELONGATED WORKPIECE (Abstract of Disclosure) A method and apparatus for inductively heating the axial, generally circular end of at least two elongated workpieces having central axes wherein the ends terminate in generally flat surfaces perpendicular to the axes.  The method and apparatus includes locating the workpieces in side-by-side relationship with the axial ends facing a given direction and the respective axes being generally parallel, providing generally circular inductors matching each of the ends of the workpieces and normally spaced axially therefrom, moving the inductors axially of the workpieces until each of the inductors contact the flat surface of one of the axial ends, locking the inductors with respect to each other, retracting the locked inductors axially away from the flat surfaces a selected air gap distance, rotating the workpiece about the axes and energizing the inductors to inductively heat the axial ends of the workpieces preparatory to hardening.

Abstract: ABSTRACT OF THE DISCLOSURE         A television communication system distributes plural VSB digitally encoded TV channels via an optical transmission link to one or more distribution terminals.  At the head-end the frequency band of each of the VSB signals is shifted down to baseband and transmitted in digital format.  At each station along the network, the digitized baseband VSB television signal is converted into analog format and then reshifted through an up-converter to its original IF band so as to be compatible with the television receiver circuitry of the subscribers served by the distribution station.  Advantageously, the present invention may employ optical communication techniques for coupling the digitally encoded frequency-shifted VSB television signals between stations.  To maintain signal strength and quality, repeater units may be located in the optical communication link.          Each repeater converts an incoming optical signal to an electrical signal for amplification and then reconverts the improved electrical signal back into optical form for further transmission along the link.

Abstract: ABSTRACT        A sheet form fabric conditioner for use in a tumble dryer comprises a substrate carrying a fabric conditioning formulation exposed at the major surfaces of the sheet.  The formulation forms a thin layer on each surface and the layers are embossed with channels.  If these channels are visible after a drying cycle then sufficient conditioner remains for another cycle.  The conditioner is manufactured by a process in which a product having a layer of fabric conditioning formulation on at least one surface of a substrate of sheet form is subjected to heat and/or pressure on at least one defined area of the layer of formulation to reduce the formulation depth within that area.

Abstract: MACROMOLECULAR GLYCOSIDASE SUBSTRATES                     ABSTRACT OF THE DISCLOSURE Macromolecular compositions are provided which find use as glycosidase substrates, particularly where steric modulation of enzyme activity is involved.  The compositions have a macromolecular hub to which is linked by means of a spacer arm a chromophore, which in turn is bonded to a sugar by an enzymatically labile glycosidyl linkage.  The chromo-phore is chosen so as to undergo a substantial change in its chromophoric properties upon cleavage of the glycosidyl linkage.  The enzyme activity can be determined spectro-photometrically due to the change in the absorptive or fluorescent properties of the chromophore upon cleavage of the glycosidyl linkage.  Varying turnover rates for the enzyme are observed depending upon the nature of the macromolecular hub, the spacer arm, and the chromophore.
