    Abstract: A pair of dielectric plates have control electrodes formed on oppositely positioned broad surfaces thereof, there being an evacuated narrow space formed between such surfaces to provide paths for an electron beam between a cathode and a target. Such surfaces have conductive control electrodes formed thereon, the electrodes on one of the plates including paired electrodes arranged in a coded finger pattern defining electron beam channels between the cathode and target. The electrodes encompass substantially all of the plate surface area between which the channels are formed. Binary control signals are utilized to apply potentials to preselected ones of said electrodes to create transverse electric fields in the channels bounded thereby, thereby aborting the electron beam in such channels. The beam is in this manner permitted to pass through channels of the scanner in which there are no transverse fields so as to excite the target portions located by these channels.

    Abstract: A small automatic test system having input connections for a multiplicity of test points from an outside system to be tested. This test unit rapidly scans through the test points and measures the voltage value at each point as compared to a predetermined tolerance range recorded in the test system memory, giving a GO and NO GO type of display along with the measured value and the corresponding test point number of a NO GO measurement. The limits defining the tolerance range for each test point measurement are loaded into the memory from a magnetic tape unit or from a manual loader, which units are parts of the present test system. The tape may be pre-recorded or made up on the test system itself. Operating speed of the system is over 2500 test points per second.

    Abstract: A plurality of flat coded dynode members are sandwiched between an electron emitting cathode in the form of flat plate and a flat target plate. Each dynode member has a plurality of apertures formed therein which are aligned with corresponding apertures on all of the other dynodes, each such set of aligned apertures forming an electron beam channel. The dynodes also each have a pair of separate conductive finger patterns, the finest of such finger patterns defining an elemental scanning area of the target plate. The finger patterns and number of dynodes utilized are chosen so as to provide a predetermined number of simultaneous scanning beams. A modulation grid having apertures therein corresponding to the apertures on the dynode and having separate portions covering the areas encompassed by each of the scanning beams is placed between the cathode and target to control the energization of the beams.

    Abstract: The square wave output of a crystal clock pulse generator is operated on by logic circuitry to start a ramp generator exactly at the beginning of one clock pulse. The signal which started this ramp generator is delayed for a predetermined time and then used to start an identical ramp generator exactly at the beginning of a later clock pulse. Outputs of the ramp generators are fed respectively to the opposite-polarity inputs of a difference amplifier, so that the amplifier output is a pulse started by the first ramp generator and stopped by starting of the second ramp generator, and the output pulse width is a precise multiple of the clock pulse period. Calibrating circuitry, when actuated, bypasses the delay function and allows comparison of the two ramp generator outputs simultaneously. If they are equal as they should be, the output of the difference amplifier is a straight line.

    Abstract: A plurality of control plates are sandwiched between an area electron source and a target, such control plates having apertures formed therein, the apertures of successive plates being aligned to form a plurality of electron channels between the electron source and the target. First control plates are utilized to direct electrons to a selected area of the target and have a first and second set of control electrodes arranged in parallel strips thereon, the first set of strips being orthogonal to the second set. The electrode strips each encompass a plurality of rows or columns of the apertures and thus define the height and width of the characters to be displayed. Second control plates are utilized to form the symbols to be displayed and have apertures formed therein aligned with the apertures of the first control plates to form a portion of the electron channels between the electron source and the target. The second control plates have mutually orthogonal strip electrodes formed thereon which are selectively energized to permit electrons to pass through portions thereof so as to define the symbols to be displayed.

    Abstract: Computing circuitry for a monitoring system to computationally detect the occurrence of a transition which is derived from a time relationship of received input signals. Aperture computing circuitry selectively measures sampled aperture signals produced from the received input signals and circuit storage circuitry categorizes the sampled aperture signal in accordance with its measured time duration by computing a lane or zone status which is stored therein. The zone status data is further processed by a comparator circuit which computationally detects the occurrence of a monitored transition.

    Abstract: An indicator or monitor is disclosed which shows whether each of a plurality of phase lock loops are locked onto their respective incoming signals or not. The output of a single in-phase detector which is time-shared by the several loops is fed to a reset integrator, then a level detector, and to the set-reset terminals of a plurality of flip-flops. The flip-flops are sequentially clocked by respective timing signals corresponding to the occurrence of the incoming signals associated with their particular loop. The output state of each flip-flop drives an indicator lamp circuit to show the desired locked or not locked condition.
