Abstract: ELECTRONIC COMMUTATION FOR DIRECT CURRENT ELECTRIC MOTORS     Abstract Of The Disclosure A Direct Current electric motor comprises a stator con-sisting of a plurality of coils interconnected to one another, and a plurality of gate controlled solid state rectifiers responsive to forced commutation below a particular rpm and self-commutation above said rpm which are connected to the junctions of the coils for selectively conducting current into and out of the stator coil junctions in dependence upon which of said rectifiers is rendered operative.  This produces a plurality of stator poles which are angularly displaced from the poles of the rotor of the motor and which shift in position as the rotor rotates.  A plurality of trigger assemblies are provided for controlling the energization of the various gate electrodes, each of said trigger assemblies comprising a pick-up coil which forms a portion of a frequency selective circuit whose resonance frequency varies in dependence on the position of a magnetic element that is moved relative to the pick-up coils as the rotor rotates.  A sine wave oscillator is coupled to the frequency selective  circuits in the trigger assemblies, the oscillator being operative to produce either of two different output frequencies, and an electronic switch responsive to the speed of rotation of the rotor selectively changes the output frequency of the oscillator.  One of these frequencies induces trigger assembly operation at all rotor positions and advanced SCR trigger timing for reliable starting and very low speed operation.  The other frequency retards SCR trigger timing for most efficient motor running at moderate and high speeds.

Abstract: FINISHING INSERT WITH IMPROVED CHIP CONTROL               ABSTRACT OF THE DISCLOSURE           A finishing insert for use with an indexable cutting tool is formed from a flat wafer of cutting material which  is  generally polygonal in plan form and includes a pair of  opposed faces and a plurality of upstanding side walls extending therebetween.  The juncture of the  side walls with each face defines the cutting edge of the insert.  The polygonal insert includes a plurality of radiused corner portions and is provided with at least one non-planar insert face wherein the corner portions thereof slope inwardly towards the opposed face of  the insert.  Each corner portion further includes a pair of generally triangular chip grooves separated by a planar central triangular land area.  Each chip groove is spaced from the peripheral cutting edge of the insert to define a side land area which increases in width from the corner portion to  its opposed end.  In addition each chip groove increases  in both width and depth from the corner portion to its opposed end.  Each peripheral edge of the insert is generally trough-shaped in configuration and includes a central planar undercut area.  Each peripheral edge further includes a V-shaped land area with the apex thereof being disposed closest to but spaced from the undercut area.  The unique configuration of the chip grooves and the peripheral edges of the insert function to reduce the forces imposed on the insert and enables the insert to be utilized over a wide range of feed rates and at various cutting depths corresponding to finishing operations, while simultaneously increasing the life of the insert.

Abstract: ABSTRACT OF THE DISCLOSURE    An alternating current code, alternately transmitted in each direction through the rails of a railroad track section, includes a selected number of pulses of alternately positive and negative polarity similar to a bi-polar DC code.  Data is transmitted by pulse length, with long and short pulses repre-senting binary digits 1 and 0, respectively.  The code pattern, polarity and pulse length, is balanced to eliminate code dis-tortion by track energy storage.  The code pattern transmitted is determined, and received pulses are decoded, by a micro-processor with associated memory (PROM) which processes local input and output data.  The processor also checks the operation of the associated apparatus, including input and output circuit and hardware integrity through monitor devices and feedback signals.  A unique check signal output is produced only when the various monitor networks determine all operation is proper and that the various elements are free of faults.  The genera-tion of operating energy for the associated apparatus by a power supply unit is dependent upon its continued reception of this check signal from the processor.  Absence of the check signal indicating apparatus fault or operational failure shuts down the system operation at that location.

Abstract: Abstract of the Disclosure A video composition apparatus and method select segments from image source material stored on at least one storage media and denote serially connected sequences of the segments to thereby form a program sequence.  The apparatus and method employ pictorial labels associated with each segment for ease of manipu-lating the segments to form the program sequence.  The labels are displayed on an ordered spatial array of display monitors to simulate the temporal relationship between the segments in what is typically a non-temporal display.  The composition control function is highly user interactive and responds to user commands for selectively displaying segments from the source material on a pictorial display.  The control function allows the user to denote a start and end of each of a plurality of selected segments to form defined segments, identify each selected segment by a pictorial image segment label which is displayed as described above, and assemble or sort the labels into a serially connected label sequence corresponding to a serially connected segment sequence.  The sort mode of operation employs continuous looping of the displayed segment(s) to aid in the composing process.  The apparatus further features trimming the segments to a desired length and adjusting if necessary the transition between segments. The sort, trim, and splice operations all are effected without rearranging the segments on the storage media.
