Abstract: TERMINATOR MEMBER FOR FUSIBLE ELEMENT        OF A HIGH VOLTAGE FUSE            ABSTRACT:  A metallic terminator member is mounted at each end of a support member for a fusible element of a high-voltage fuse.  Each terminator member has a serrated tab projecting into the normal path of the fusible element so that the fusible element cart be easily welded to the serrated tab without being distorted and at reduced welding temperatures to avoid damage to the fusible element.          The terminator members also have positioning fingers that position the terminator member within the fuse housing and a tab for attaching the terminator member to the end ferrules of the fuse.  The terminator members also include a center keyed opening that receives the support member and positions and retains the support member.  A wire retainer can be used to engage grooves in the ends of the support member that extend through the keyed opening to lock the terminator member to the support member.

Abstract: ABSTRACT OF THE DISCLOSURE Disclosed is a predictive encoder in which undesired redundancy components are effectively suppressed without causing an increase in quantizing noise and a deterioration in picture quality, in the case of video signals.  A predictive encoder according to this invention comprises circuitry for producing a predictive signal, a device responsive to an input signal and the predictive signal for producing a predictive error signal representing a difference therebetween, and a quantizer responsive to the predictive error signal and having a non-linear quantization characteristic for producing information codes.  The non-linear character-istic for the quantizer is that a transmission gain is set at a value smaller than unity within a sufficiently small amplitude range and at a value substantially equal to unity for amplitude ranges beyond said sufficiently small amplitude range.  With this invention, the amplitude distribution for the predictive error signal is concentrated in a smaller amplitude region by passing the predictive error signal through the non-linear quantizer, whereby the information codes can be reduced   Even if minute waveform distortion is introduced by the non-linear characteristic, it is hardly detected as deterioration.  Further, the quantization noise does not increase, because the quantization steps are made finer than or at least equal to the conventional system.  In the composite predictive encoder according to this invention, because the interframe predictive error signal for the still-motion picture is small, the amplitude thereof is suppressed.  Therefore, the noise components are also suppressed.  On the other hand, the interframe error signal for a rapidly moving picture, which is of relatively high level, is encoded without resort to amplitude suppression, whereby blur can be prevented.

Abstract: ABSTRACT OF THE DISCLOSURE A sequencing die and method for forming truss webs or links from metal tubing includes as a first step providing a continuous length of tubing to a die assembly operably engaged by a mechani-cal press wherein the end portion of the tubing is flattened by flat-tening means to form a first flattened web end. Sequentially follow-ing without any further flattening the web end is punched by punch-ing means located in the flattening means to form a cross pin re-ceiving hole and a terminal end portion,  The tubing is then ad-vanced in the die assembly whereupon it is again flattened and punched sequentially by  the flattening and punching means respect-ively to form a second web end.     Gripping means located on the sequencing die outwardly adja-cent the die assembly grip the tubing during the forming of the webs. They are configured for movement relative to the die assembly to allow lateral displacement of the tubing during flattening align-ing the web ends with the  longitudinal centerline of the tubing.     Indexing means allows longitudinal indexing of the first web end relative to the die assembly allowing accurate separation of the second web and for consisting predetermined web lengths. It includes antitwisting means to prevent angular twisting of the web ends relative one another during forming.

Abstract: FORMAT CONTROL SYSTEM AND METHOD     Abstract of the Disclosure System for, and method of, controlling text format upon playout from a text buffer loaded from segmented media, such as magnetic cards.  At the beginning of a job and during input keying, format information, made up of locations setting tabs, the measure length, index values, adjust modes, etc., is stored in a text buffer.  The keying of this information causes appropriate printer format control settings.          Text to be formatted and controlled by the printer according to this format information is then keyed and stored in the text buffer.  A later change in format for the same page of the job is handled by keying new format information.  This results in new printer tab, etc., settings.  This new format information is also stored in the text buffer.  Upon later recording onto a magnetic card, all format information is stored on the card along with the text.  Also, the last format information recorded on the card is written into a format buffer.  This last format information will remain in control until new format information is keyed and stored for a subsequent page.  Thus, a history of format information from a previous card will be preserved in the event editing of text overlapping two consecutive cards becomes necessary.

Abstract: Abstract of the Disclosure Intermediate a component inserting machine and its lead clinching mechanism, a turret-type work support carries one or more detachable circuit boards and is rotatable about a vertical axis as well as movable in their general plane under the control of programmed power means.  The latter is effective to cause a pivot means on the support and a cooperative surface or s?op means to shift the support and its boards angularly at predetermined times and to a predetermined extent.  Accordingly, without need to angularly reposition the inserter or clinching means, the automatically positioned work support enables the boards to receive components in various predetermined angular relations (most commonly at right angles, and boards may be loaded and unloaded on the turret while other boards thereon are concurrently having components mounted therein.      The arrangement avoids the hazard present when boards are manually repositioned, and generally enhances productivity.

Abstract: IMPROVED SAMPLING FILTER-DETECTOR                           ABSTRACT      A sampling filter-detector receives input signals of different frequencies and provides an output, or detect signal, only when the input frequency has a predetermined value essentially equal to the drive frequency of the sampling circuit.  The input signal is coupled through a series of solid state switches, or multipliers, to storage, or sampling, capacitors,  the average voltages of which are coupled through-voltage peak and valley followers to a comparator which supplies an output or detect signal only when the difference between the positive and negative voltage inputs to the comparator is greater than a certain value.  This occurs when the input frequency is within the detector bandwidth.  A threshold voltage of a desired value may be placed in the circuit coupling the peak follower and the positive input of the comparator.  The solid state switches are turned on and off by pulses from digital logic means such that the switches are on 120° apart in time for the drive frequency which is equal to the frequency to be detected by the filter detector.  The response to the third harmonic of the input signal fundamental is eliminated as are multiples of the third harmonic.
