摘要： A method of controlling and operating a fluid dispensing apparatus is provided which modifies a tool speed signal from a robot and generates a corrected signal to a dispenser nozzle flow controller to compensate for non-linear flow characteristics of fluids, such as non-Newtonian adhesive fluids, to maintain uniform bead size as the tool speed varies. The corrected tool speed signal is generated by computing the ideal flow for the tool speed, comparing the computed flow with actual flow data stored in memory using linear interpolation of data between the stored values, and generating a control signal modified in accordance with the comparison. The stored data is acquired by operation of the apparatus in a calibration mode wherein a series of standard signals is sent to the fluid controller while the actual flow at each signal level is measured and stored in a table. The method corrects for non-linear flow phenomena such as that known as the shear-thinning effect that is flow rate dependent.

摘要： A system for monitoring energy radiant from a material dispensed onto a substrate. As disclosed, an infrared sensor is positioned to receive infrared energy radiated by a substrate and by a heated adhesive applied to the substrate, with the resistance of the sensor varying in dependence upon the amount of infrared energy received. An amplifier has an input capacitively coupled to the sensor, and the voltage at the amplifier input varies in dependence upon the resistance of the sensor. The output voltage of the amplifier varies in dependence upon the amplifier input voltage, and hence upon the amount of infrared energy reaching the sensor. In order to prevent inaccuracies in the amplifier output signal due to, for example, temperature-related resistance variations of the sensor, the amplifier input is grounded during intervals when the sensor receives infrared energy from the substrate and ungrounded shortly before the sensor begins to receive infrared energy from the heated adhesive.

摘要： A projector for motion picture film includes a servo motor which is controlled to advance film frame by frame to a projection station. A capstan on each side of the projection station is controlled to maintain film loops of substantially constant size and an associated reel motor delivers film to and takes film from each capstan. Each associated capstan and reel motor are controlled so as to maintain substantially constant tension on the film. A film guide defines the projection station and also includes provision for masking peripheral areas of each frame. Each capstan and an associated pinch roller are designed so as to eliminate creeping of film from between the two. A circuit for controlling the reel motors is arranged to permit fast winding of film directly from one reel to the other with an automatic braking feature.

摘要： A dispenser for fluid under pressure has a sensor affixed to it to sense the pressure of the fluid proximate the dispenser discharge opening to generate a pressure reflective signal. A comparator is connected to receive the pressure reflective signal to compare the pressure signal with a preselected band of pressure values which are selected to reflect operating pressures when the dispenser discharge opening is opened. The comparator generates a malfunction signal when the sensed pressure signal is outside the preselected band.

摘要： A pressure transducer (58) generates an instantaneous pressure of a pressurized liquid, such as an adhesive, sealant, or caulk, being dispensed from a dispenser (52). The signal is received by a filter for filtering out non-bubble pressure disturbances. The filter includes comparators (106, 108); detection circuitry (112, 120) and timers (116, 124) or counters. An alarm indicating the passing of a bubble is indicated in response to signals which pass both the filters.

摘要： Apparatus and method for dispensing fluid materials wherein the fluid is discharged from a nozzle at a rate controlled by a metering valve having a seat and a stem moveable with respect to the seat to modulate the flow. A servo-actuator connected in a feedback control loop is used to position the valve stem with respect to its seat in accordance with a control signal. The control signal is derived in accordance with the difference between a driving signal representing a desired flow rate and the sum of a pair of feedback signals. One feedback signal represents the actual flow rate while the other feedback signal is correlated to both the relative velocity and position of the stem with respect to the seat. The position-dependent velocity signal is generated by a transducer comprising a magnet and a coil influencable by the field of the magnet as the magnet and coil move relative one another. For any given velocity, the magnitude of the position-dependent velocity signal is greater when the stem and seat are close together than when they are further apart so that as the valve closes, the amount of feedback increases.
