Abstract: ABSTRACT OF THE DISCLOSURE A Stored Program Controlled telecommunication system comprises test points, operating points,data storage registers connected to each other through a data bus, a phase generator and an access signal generator.  The registers include instruction registers for storage of instructions, and an address register for storage of address numbers identifying the instructions.  The address register is provided with a stepping input for raising its content with one unit.  The phase generator produces phase signals by which the processing cycles of the instructions are divided into phases.  The access signal generator is controlled by the phase signal, the address numbers and the instructions.  For producing access signals in order to control the test points, operating points and registers, the access  signal generator includes logic arrangements.  A first logic decodes the content of the address register during the beginning phase of the respective cycle and accesses the instruction register associated with the respective address number during the other phases of the cycle.  A second logic activates the stepping input during a middle phase of each cycle.  A third logic allows transfer of an address number from one of the registers to the address register only during the end phase of the respective cycle. A fourth logic carrying out an AND-function has its inputs activated during the end phase of a cycle for accessing one of the test points and by the one binary state of this test point, and its output connected to the stepping input.

Abstract: ABSTRACT OF THE DISCLOSURE              The shutter includes a curtain formed of elongated bars hinged to one another at longitudinal edges and guided at their ends in laterally spaced guide grooves extending along opposite sides of an opening to be controlled by the shutter.  A rotatable member is mounted in an upper reversing zone, such as a lintel above the opening, and the rolling bar curtain is trained about this member for direction reversal during raising and lowering.  The laterally spaced guide grooves extend along the peripheral portion of this rotary member and are then branched to form branch guide grooves extending downwardly from the rotatable element into a recess formed in the lintel or the like.  Guide elements, such as pins or rollers on the ends of each bar, cooperate with the branch guidon grooves to conjointly guide the bars to form at least one vertical pile of bars superposed in horizontal orientation in the recess, responsive to raising of the curtain.  The rotatable element may be circular or may be polygonal and, if polygonal, has sides each conforming to the width of a bar of the curtain.

Abstract: SINGLE DECODER BUBBLE DOMAIN CHIP ORGANIZATION by Peter K. George ABSTRACT    A unique arrangement of magnetic bubble domain devices is utilized to provide an advantageous chip arrangement.  One or more storage registers are associated with a controlling path whereby information, for example in the form of magnetic bubbles, is transferred into or out of the storage registers.  The controlling path includes replicate/transfer switches for permitting the bubbles to be transferred into or out of the storage register.  A generator and an annihilator are provided for producing or destroying magnetic bubble domains.  A single decoder is utilized to determine the action to be taken by the controlling path and, thus, the overall operation of the storage register within the chip.  A multiple input detector is connected to receive the information from each of the storage registers and to produce a chip output signal.  Electrical means are utilized to control the selective operation of the various components of the controlli path.

Abstract: ABSTRACT           The present invention relates to the steering of a light beam with an articulated and fixed mirror pair to the surface of a video disc.  Prior art attempts to adjust the reading beam involved in the coarse manipulation of the light source to direct it to the video disc surface.  The present invention provides an improved apparatus and method for steering the light beam.  In accordance with the invention, an optical system having a source for producing a reading beam of radiation is pro-vided.  The beam follows an optical path to the surface of the video disc.  A pair of mirrors disposed in the optical path are arranged in opposing spaced relation to one another to cause the reading beam to be reflected at least once from each of the mirrors.  At least one of the mirrors is articulated to steer the reading beam to a precisely selected location on the surface of the video disc.  The mirrors may be planar and have their respective planar reflecting surfaces lying in parallel planes and at an angle to the reading beam.  The articulated mirror can be arranged to steer the reading beam radially and/or circumferentially of the video disc.

Abstract: ABSTRACT      Circuitry for generating a sine wave and/or a cosine wave from a pulse signal wherein cyclically repeating pulses each generate one cycle of a sine wave and/or a cosine wave.          Each pulse institutes a sawtooth signal; a square wave generator produces a square wave having a positive excursion for one-half of the sawtooth signal and a negative excursion for the other half of the sawtooth signal.  The square wave signal is integrated to produce a triangular wave.  The triangular wave may be shaped into a simulated harmonic wave by wave-shaping circuitry.  If both sine and cosine waves are desired, additional circuitry is employed to convert the described square wave to another square wave of the same frequency, 90° out of phase with the first square wave.  The other square wave is converted to a corresponding triangular wave which is shaped to a simulated harmonic wave by wave-shaping circuitry.    Additional circuitry may be provided to compare the two square wave signals to assure that the resulting harmonic waves are in the desired phase relationship, i.e., a leading or lagging relationship as desired.
