Abstract: ABSTRACT         A telecommunication switching system adapted to be connected to lines and trunks, has a digital switch network and a control complex for executing system operational functions by program operated processors in response to dialed numbers received from stations in separate customer groups.  Customer groups are groups of stations on discrete sets of lines served by the system, all customer groups sharing the hardware forming said switching system while all operational functions are normally separately executed for each customer group in response to dialed numbers included within a separate comprehensive number plan for each customer group.  Representative system operational functions include processing standard calls between stations on lines in the same customer group and processing conference calls between multiple stations.  The control complex provides a dialed number to function translator in the form of addressable data base memory which provides function-instruction data in a multiple level table structure of separate groups of locations for each customer group of stations, each location having coded electrical signals representing an identifier word including an instruction to execute one system operational function.  The data base memory also provides restricted class of service information among customer groups.  The processors address locations in memory fields in response to coded electrical signals representing an originating station, and address locations in the table structure in response to the combination of coded electrical signals representing a dialed number received from said originating station and those identifying the customer group of said originating station.

Abstract: WEB SCANNING APPARATUS                Abstract of the Disclosure A flying spot is used to scan a web completely across the web from a leading to a trailing edge plus an additional distance on each side with the apparatus being initiated automatically as the leading edge is reached and ceasing an output when the trailing edge is reached.  The web might be a paper web, for example, being scanned to determine the two edges, and also  to determine defects including holes and wrinkles in the web.  The flying spot is rectangular with the length of the  rectangle parallel to the moving direction of the web and this flying spot rectangle traverses from one side to the other of the web.  A hole in the web gives less than average reflected illumination to a detector, whereas a wrinkle gives increased illumination to the detector.  The circuit differentiates the raw signal so that a hole, or dark signal, gives a positive and then a negative going pulse, whereas a wrinkle, or lighter signal, gives a negative going pulse followed by a positive pulse.  The circuit discriminates between the leading web edge, which is a negative going pulse after differentiation, and the negative intial pulse of a wrinkle.  The circuit also discriminates between the positive going pulse of the trailing web edge and the positive initial pulse of a hole in the web.

Abstract: ABSTRACT            An expandable abrading tool disclosed includes a rotatable arbor and an abrasive insert having stacked washers which receive the arbor and are mounted thereon in a clamped relationship.  Each washer has a round outer edge including an abrasive secured thereto for performing a cutting operation upon tool rotation.  The washers each have a frustoconical shape that points towards one axial end of  the insert.  A threaded clamp which provides a means for clamping the ends of the insert is adjustable to increase the clamping force in order to flatten the washers and thereby control the washer diameters.  The insert can thus be initially sized for use and can be adjusted to compensate for wear of the abrasive.  Different embodiments of the abrasive insert include the washers with slightly smaller spacers interposed therebetween in an alternating relationship, the washers directly engaged with each other, and flutes in the outer edges of the washers.  It is perferable but not absolutely necessary that the flutes be aligned in an axial relationship along the insert length.  The washers are made from a suitable spring metal, preferably a copper alloy such as bronze with a component such as beryllium, so that the clamping force required to provide the flattening thereof is not too great. The flutes also lessen the required clamping force to flatten the washers.
