Abstract: An apparatus and method for monitoring the incoming transducer signal or synchronizing signal from an optical encoder in real time and display the degree of stability. The incoming transducer signal or optical encoder signal comprises of a certain number of voltage pulses. The number of pulses for a set period of time is measured to develop an actual frequency of voltage pulses per set unit of time. Furthermore, a representative numerical value for the time between two adjacent pulses is also developed. This time between adjacent pulses is altered by means of a look-up table to develop an average pulse frequency for that same set period of time. The average value for this period of time is then compared against the actual frequency of voltage pulses per set period of time. This comparative value can then be outputted to a display.

Abstract: A dust control mat having a pile upper surface and a thermosetting rubber or rubber-like backing to which a thin thermoplastic identification strip or label has been vulcanized thereto.

Abstract: An ink composition for Gravure printing is provided with a poly(oxyalkylene) substituted colorant and a vehicle which is a water-in-oil emulsion of a water immiscible organic phase and an aqueous phase, in the range of 9:1 to 1:1, thereby significantly reducing VOC emissions, with no detrimental effect on print quality.

Abstract: An apparatus and method for reproducing the color of blended colorants on an electronic display such as a cathode ray tube, liquid crystal display or other type of electronic device that utilizes RGB values. Predictions of blended colorants on or in substrates can be made from XYZ measurements of samples prepared with no colorants, one colorant, and pairs of colorants. The calculation method uses light absorption, light scattering, and light absorption blend coefficients. An image digitizer can be used to obtain XYZ values from samples. Furthermore, image digitizer RGB values are converted into XYZ values with a non-linear model using a simple method. Furthermore, the above process to generate XYZ values from image digitizer RGB values can be used to generate RGB values from XYZ values for electronic display.

Abstract: An apparatus and method for creation of moire fabric by moving textile fabric over a member, with a longitudinal axis, having several areas of a lesser width or diameter along the longitudinal axis and several areas of a greater width or diameter along the longitudinal axis and sloped portions therebetween interconnecting the areas of greater width or diameter with the areas of lesser width or diameter. The areas of greater width or diameter on the member form lobes that retard the movement of filling yarns of the textile fabric by creating a longer path for the textile fabric to traverse thereby shifting the filling yarns while the areas of lesser width or diameter on the member form valleys that advance the movement of filling yarns of the textile fabric by creating a shorter path for the textile fabric to traverse. This shifting provides the proper filling pattern for the conventional moire fabric.

Abstract: The apparatus and method for contiguous valve control. This involves the inputting of data for each of a series of valves then comparing that digital valve activation data in a one and one correspondence to the digital valve activation data that was inputted to that same series of valves in the previous machine cycle. If a particular valve was turned on in the previous machine cycle, then this valve will not be applied with voltage for a percentage of the valve's machine cycle time.

Abstract: A method for weaving airbag fabric for use in protecting vehicle occupants during a collision.

Abstract: This invention relates to an improved double plush knife bearing mechanism for moving a carriage that holds a circular knife along a dove-tail track. The angle between the top portion and a first outer side portion of the dove-tail track is a first angle and the angle between the top portion and a second outer side portion of the dove-tail track is a second angle. The carriage has a bearing mechanism having a first bearing portion with a first component that is positioned adjacent to the top portion of the dove-tail track.

Abstract: An apparatus and method for load voltage compensation. This involves increasing the length of time voltage is applied to electrical components, e.g., solenoid valves, in direct proportion to the number of electrical components electrically activated to compensate for the voltage loss in the control wires leading to the electrical components. The area of compensated pulse is then equal to the area of uncompensated pulse in order to compensate for the voltage drop. The load is anticipated prior to voltage application by summing the number of electrical components and associated loads selected and applying voltage for a period of time directly proportional thereto.

Abstract: An apparatus and method for creation of moire fabric. This can be achieved by placing a first piece of fabric against a support member and directing ant least one stream of fluid at the surface of said first piece of fabric to provide lateral yarn displacement. Then delivering said stream at a peak dynamic pressure in excess of about 300 p.s.i.g. and less than 4,000 p.s.i.g. and selectively interrupting and re-establishing contact between said stream and said surface in accordance with pattern information in order to pattern said first piece of fabric. This is followed by combining said patterned first piece of fabric with an unpatterned second piece of fabric in overlapping relationship and applying pressure by means of calender rolls having smooth surfaces to said combination of said first piece of patterned fabric and said second piece of unpatterned fabric.
