摘要： The light intensity-exposure time product of a lighthouse used in the manufacture of phosphor screens for color picture tubes is held constant despite changes in the shadow mask light transmission characteristic and power supply variations. The power provided to the exposing lamp is monitored and converted to a square wave output having a frequency which varies with the power. The frequency variations change the exposure time inversely with the frequency changes to maintain the light intensity-exposure time product constant.

摘要： A system for determining the exposure time required for a lighthouse to expose the screen of a television panel in accordance with the light transmission characteristics of the shadow mask includes means for providing the actual light transmission characteristics of the shadow mask. The minimum and maximum acceptable transmission values are subtracted to form a transmission range. The actual transmission characteristics and the minimum transmission value are combined to provide a transmission difference signal. The transmission difference and the transmission range are converted into a ratio which is used to determine a transmission percentage. The percentage is combined with a maximum transmission time to establish the exposure time.

摘要： The motion of a kinescope panel on a lighthouse is made intermittent by dividing the total excursion distance into intervals. Each interval is segmented into a move time and a dwell time which are expressed as move counts and dwell counts per interval. The counts per interval are changed in accordance with the required exposure time and the intensity of the exposing energy source.

摘要： A communications link of multiple parallel communications lines includes at least one redundant line. In a first aspect, the lines are periodically recalibrated one at a time while the others carry functional data. If a fault is detected, the faulty line is disabled and the remaining previously calibrated lines transmit functional data. In a second aspect, impending line malfunction is detected from anomalies during calibration. In a third aspect, line malfunction is detected from receiver circuit output by determining a logical lane upon which each detected error occurs, and by mapping the logical lane to a physical line currently carrying the logical lane data.

摘要： Methods are provided for making a porous filter that is useful in polymer melt spinning. The methods include pressing particles, such as a metal powder, to form a filter having a filter body integrally formed with a top cap and a bottom cap. The filter body and caps are formed as a single component or, alternatively, are formed as two or three separate parts that are fitted and pressed together to form a single component having blind inlet and outlet cavities. After pressing, the component is sintered to form the porous filter. The particles are pressed and cohere to form the caps and filter body without the use of a polymeric binder, and the inlet and outlet cavities are formed substantially without machining.

摘要： A transmitter for driving a transmission medium employs pre-distortion to predistort the signals leaving the driver so that they will have an acceptable shape when they reach their destination and have been distorted by imperfections in the transmission medium. The change to pulse height is accomplished by means of a current steering unit that directs a controllable amount of current into the line for each pulse while maintaining the total sum of current that is generated constant in order to reduce noise. Control coefficients for the current steering unit are manipulated in an nxm register that automatically maintains the total number of bits constant while bits are moved from a location that controls a first current driver to a location that controls a second current driver with different properties.

摘要： Systems and methods for the manufacture of reinforced, three-zone, microporous phase inversion membrane having any one of a plurality of different possible pore sizes in any of the three zones from at least a single mother dope batch is disclosed. The systems and methods include formulating at least a single mother batch of dope in a vessel preferably maximizing the non-solvent to solvent ratio for a given weight percentage of polymer for use in a microporous phase inversion membrane production operation to produce three-zone phase inversion membranes having one of a plurality of different predetermined pore sizes in any or all of the three zones. The at least one mother dope batch is controllably formulated in at least one vessel such that the temperature of the dope does not exceed a predetermined maximum mixing temperature and is maintained at a relatively low temperature (lower than the mixing temperature) suitable for storage.
