Abstract: ABSTRACT OF THE DISCLOSURE            A reclosable bag package is provided by closing the top of a filled bag to form a neck, preferably trimming the walls of the bag to the same height, folding over a portion of the neck, preferably only once, and sealing the folded over portion of the neck to a side wall of the bag using a composite tape comprising a length of a first tape having a non setting adhesive coating on one surface and a length of a second tape overlapping one edge of the adhesive coated surface of the first tape.  The first tape seals or reseals the bag, and the second tape provides a tab for peeling the first tape partially from the bag to open the package and also provides a vehicle for coupons or other printed matter.  Apparatus is provided to close, trim and fold the bag and to form and apply the lengths or composite tape.

Abstract: ABSTRACT The two wires of a symmetrical two-wire line are connected via two halves of a terminal line resistor to respective terminals of a relatively low impedance symmetrical input arm of a return path such as a four-wire line, are each connected via a relatively high value resistor to respective inputs of an operational amplifier which leads to the go path, the inputs of the operational amplifier also being connected cross-wise via respective resistors of a value double that of the terminals of the input arm.  A thres-hold value element comprising a transistor may monitor the output voltage of the operational amplifier and change a d.c. reference voltage so that the output signals of two operational amplifiers located in the go path are sub-stantially mutually equal.  Other circuit components may serve to determine current asymmetry and to monitor loop closure.

Abstract: ANTI-REVERSAL BACKCHECK FOR PRINTER RIBBON CARTRIDGE              TAKEUP SPOOL                 Abstract of the Disclosure In a typewriter ribbon cartridge, it is necessary to maintain tension on the span of ribbon extending outside the cartridge to prevent tangling and to insure high print quality during machine operation.  One technique for insuring that adequate tension is maintained is disclosed herein as an anti-backup back check device. Connected to the takeup spool of the ribbon cartridge is a disc member supporting thereon a pair of thin flexible resilient arms with outwardly oriented pointed ends. These ends formed in the shape of points engage ratchet teeth formed around the interior surface of a cylinder. The cylinder is formed as a part of the ribbon cartridge and, thus, is permanently positioned and fixed with respect to it.  As the takeup spool disc and arms are rotated by the ribbon feed mechanism, the arms will flex and permit a rotation of the disc and takeup spool with a minimal drag force.  Upon reversal, the points on the ends of the arms engage the ratchet teeth and the arms become compression columns resisting the rotation of the disc and spool.  The center of the disc and the takeup spool are free floating within reasonable physical constraints.  The teeth of the arms are positioned such that they are one-half tooth pitch out of phase to insure that one tooth is always in engagement with a tip of one of the two pawls.

Abstract: Abstract of the Disclosure A single carrier is amplitude-modulated by a signal which is a transform (as the sine function) of the audio signal, and one set of sidebands is removed.  In a receiver, the signal can be recovered by first deriving the Hilbert transform of the sine transform, and multi-plying it by the signum of the derivative of the original audio signal to obtain the cosine transform.  The sine and cosine transforms are then decoded to obtain the original audio signal.

Abstract: ABSTRACT OF THE DISCLOSURE     A viscous fan clutch (10) is typically employed in a fan drive mechanism within a truck or automobile.  A shaft (12) driven by the engine, rotates a clutch member (24) within the fan drive.   The clutch member is arranged for fluid engagement with a cover assembly (38) for the transmission of torque thereto when the fluid is disposed in an operating chamber (70) defined by complementa6y shear surfaces (30, 31, 56, and 57) in the clutch anc cover.  During the relative rotation between the clutch and cover, fluid is pumped from the operating chamber to primary (76) and secondary (77) fluid storage chambers.  A fluid temperature responsive control valve (190) provides for selective communication between the storage chambers and the operating chamber to effect modulation of the total fluid flow whereby quasi dual speed operation of the clutch is achieved.  Upon receipt of a signal from a control circuit (146), a first measure of viscous fluid (from the primary storage chamber) flows rapidly into the operating chamber to effect a step speed increase. Subsequently, a second measure of viscous fluid (from the secondary storage chamber) flows slowly into the operating chamber to effect a second, gradual speed increase.  In the preferred embodiment the valve operates in response to sensed engine liquid coolant temperature.

Abstract: E.Kieale -2 Abstract In color-picture tubes, a maximum of three photode-tectors disposed behind the slit of a diaphragm in front of the screen center are used to determine deviations from color purity by measuring the lumi-nance distribution, and deviations from convergence by measuring the time sequence of the phosphor-stripe illuminations.  By means of magnetizing cur-rents in suitable deflection means, the measured deviations are compensated for.  The strengths and directions of the compensating currents determine the magnitude and direction of the correction.      With this method, the measurement of deviations for performing corresponding adjustments can be auto-mated at low cost.

Abstract: ANTIMICROBIALLY TREATED FABRIC CONSTRUCTION               Abstract of the Disclosure A unique fabric construction having a backing fabric and a face fabric.  At least one of the fabrics is made at least, in part of yarns formed from synthetic fibers which have incorporated thereinto an antimicrobial agent.  In some embodiments a tie yarn joins the two faces in plated relation.  Even with minimal contact of the yarns in the two fabrics, the antimicrobial agent migrates from within the treated fibers in the one fabric to the surface thereof and transfers to the yarns in the other fabric.  Thus there is imparted antimicrobial protection to both fabric faces while maintaining the advantages of naturally occurring, untreated fibers in one of the fabrics.

Abstract: ABSTRACT OF THE DISCLOSURE     An alarm bell assembly is provided herein, the bell assembly includes a gong and bell operating parts on a mounting, the operating parts being concealed and protected by the gong, and preferably also a cover for the assembly.  The bell assembly is secured by means comprising a detector, such as a micro-switch, by which the bell is actuable when the securing means is tampered with.  A rechargeable battery is connected to an external control circuit such that the battery remains fully charged and supplies the alarm drive if the control circuit connected is served.          Thus the alarm bell is sounded if a prospective burglar or intruder attempts to dismantle the assembly, since the gong and the cover are secured to the assembly in such a way as to be in operable contact with the micro-switch which is connected with the power source and bell operating means.  The assembly will therefore sound the alarm on being meddled with, and so serve to disturb burglars and intruders and prevent the alarm being disable.
