Abstract: A paint spray rig is disclosed for applying "high gain" reflective paints to a motion picture projection screen. The rig includes a tower which extends vertically of the screen and which can be indexed laterally across the screen. A paint spray head is carried by a carriage assembly that is vertically movable on a tower. The spray head can be moved towards and away from the screen under the control of ultrasonic sensors that measure the distance between the spray head and the screen, for maintaining the distance substantially constant. The spray head can also be moved progressively in the vertical direction with respect to the carriage so that it is at the bottom of the carriage for painting the bottom edge of the screen and at the top of the carriage for painting the top edge of the screen. The spray head can also be swapped from one side of the carriage to the other for painting opposite side edge portions of the screen.

Abstract: A method of and an apparatus for coating a substrate with a polymer solution to produce a film of uniform thickness, includes mounting the substrate inside an enclosed housing and passing a control gas, which may be a solvent vapor-bearing gas into the housing through an inlet. The polymer solution is deposited onto the surface of the substrate in the housing and the substrate is then spun. The control gas and any solvent vapour and particulate contaminants suspended in the control gas are exhausted from the housing through an outlet and the solvent vapor concentration is controlled by controlling the temperature of the housing and the solvent from which the solvent vapor-bearing gas is produced. Instead the concentration can be controlled by mixing gases having different solvent concentrations. The humidity of the gas may also be controlled.

Abstract: A robot control apparatus does not require an expert to perform programming, prepare teaching data or reprogram the motions of a work robot. The controller for the robot accepts the teaching point instructed by a beginner operator, and computes the start and end points in a track from the input teaching points. The controller also computes target start and end points in each of the passes in the track based on the current track points and the overspray width input by the operator and automatically allows for the overspray width. The control apparatus therefore facilitates operation of painting tasks which conventionally required a labor-intensive effort in reprogramming by an expert operator.

Abstract: A paint injector for digital printing in which paint is deposited in metered amounts on a print medium comprising a wheel rotatable by a shaft of a motor, an idler disposed in a paint reservoir, and a segment of wire disposed around the wheel and the idler. The motor is preferably computer controlled such that the rotation of the wheel and thus movement of the wire is selectively controlled. As the wheel is rotated, paint contained within the paint reservoir coats the wire and is thus drawn by the wire in front of an air stream. The air stream pulls the paint from the wire and carries it toward the print medium. By employing a plurality of such paint injectors into a single print head, each containing a different color of paint, and secured to a computer controlled, movable carriage positioned over the print medium, a digital image can be painted by the print head on the print medium.

Abstract: A nozzle having a series of orifices along a longitudinal length of the nozzle for processing a substrate and which is rotatably adjustable. By the nozzle design of the present invention, liquid is properly distributed along the longitudinal length of the nozzle independently of the angle of the aerosol spray. This allows for the generation of a uniform aerosol stream that is independent of spray angle. The nozzle design of the present invention improves the uniform distribution of liquid within the nozzle, which in addition to providing a more uniform liquid pooling, also substantially eliminates temporal non-uniformities across the nozzle length. Moreover, the present invention is also directed to a nozzle that is translatable in the direction toward or away from the substrate to be processed or parallel to the substrate surface.

Abstract: A system for improving accuracy of application of a fluid to a desired area of an object which is moving transversely to the direction in which the fluid, e.g., an adhesive, is emitted from a nozzle via an electrically actuated valve. Photoelectric or other such detecting means are positioned in known distance from the nozzle to generate a signal in response to presence of fluid at that position. The delay time between detection of the moving object at a predetermined position and generation of the signal to open the valve is varied commensurately with the time period between generation of the valve-opening and fluid-detection signals of the preceding cycle. The variable delay time thus reflects more accurately the actual electrical and mechanical response times of the valve as opposed to an estimated, fixed delay time. A second detector may be spaced a predetermined distance along the path of adhesive flow from the first detector to provide measurement of fluid velocity.
