Abstract: A method of controlling an expansion valve including the steps of: measuring a primary system condition; determining an error in the primary system condition; measuring a secondary system condition; determining an error in the secondary system condition; and modulating the expansion valve based upon the larger of the first or second error.

Abstract: A security document is prepared by designating specialized tiling elements to be printed in selected image element cells across the face of the document. In accordance with one embodiment of the present invention, a method of preparing a security document is provided comprising the steps of: (i) designating a security image area on a face of a document; (ii) dividing the security image area into a plurality of image element cells, such that the image element cells define an array of image element cells across the security image area; and (iii) designating respective printed tiling elements to be printed in selected ones of the image element cells to define a printed security image and a printed complementary security image within the security image area. Individual ones of the respective printed tiling elements comprise printed units positioned within the respective image element cells.

Abstract: A method of measurement. The method comprises the steps of (a) measuring a value, (b) forwarding the measured value as an analog signal, (c) dithering the analog signal to improve resolution and (d) converting the analog signal to a digital signal.

Abstract: A control valve assembly for flushing a sanitary fixture includes a burst valve for supplying flush water flow at the beginning of a flush cycle and an independently controlled bypass valve for providing trap reseal flow after the burst valve closes. The burst valve includes a timing sleeve cooperating with a lifting piston to define a timing chamber communicating with inlet pressure through an orifice. A piston collar cooperates with the lifting piston to define the bypass valve. A lifting chamber defined between the body and the lifting piston communicates with the outlet through a metering valve assembly. Actuation of the metering valve assembly empties the lifting chamber and lifts the timing sleeve, opening the burst valve. The burst valve is closed when the timing chamber fills at a rate controlled by the orifice. The bypass valve is maintained open by pressure differential across the bypass valve to supply trap reseal flow until the metering valve assembly recloses.

Abstract: An upper housing shell of a hermetically sealed refrigeration compressor has a central asymmetrical section interposed between a lower cylindrical section and an upper spherical section. The shape of the central section is such that opposite points define a line that is perpendicular to the surface at one point, but is not perpendicular to the surface at the opposite point.

Abstract: The existence of inverted start conditions in a refrigeration chiller is accurately identified by sensing the liquid level in the chiller evaporator. That liquid level is indicative of the location of the chiller's refrigerant charge at start-up. If the sensed liquid level is below a predetermined level, an inverted start condition is verified to exist. Failed starts and chiller system shutdowns are reduced or avoided as compared to systems in which less reliable indicators are used to identify the existence of inverted start conditions.

Abstract: A rebound cushion for a body mount is disclosed. The rebound cushion includes an outer cushion formed from an elastomeric material having a first durometer. The rebound cushion also includes an inner cushion formed from an elastomeric material having a second durometer, wherein the first durometer of the outer cushion is higher than the second durometer of the inner cushion. A clamp disk maintains the inner cushion in contact with the outer cushion. The outer cushion may include an annular lip for retaining the clamp disk. The separate inner cushion allows a vertical cushioning rate defined by the inner cushion to be designed and/or tuned independently from the lateral cushioning rate.

Abstract: The present invention is directed to the deliberate cancellation of MICR-readable documents by applying a penetrating ink through the MICR line of the document wherein the ink contains magnetic particles which disrupt the reading of the MICR line by the MICR reader. The magnetic particles in the ink do not penetrate along with the other ink components, but remain on or near the surface of the document. These extraneous magnetic particles interfere with MICR readers by preventing accurate reading of the encoded MICR characters and cause the MICR reader to reject such a document from normal processing automatically.

Abstract: A continuous molding member to be inserted in a gap between a vehicle window and vehicle body panel, where the molding member includes a plurality of independently movable sections that allow the molding member to traverse a corner without becoming distorted. The molding member includes a stem portion having a plurality of barbed extensions at one end and a center umbrella portion at an opposite end. A first side umbrella portion is connected to the stem portion by a first branch portion so that it is positioned on one side of the center umbrella portion, and a second side umbrella portion is connected to the stem portion by a second branch portion so that it is positioned at an opposite side of the center umbrella portion. The first and second branch portions can be of a length so that the first and second side umbrella portions are positioned above the center portion opposite to the stem portion, or below the center portion adjacent to the stem portion.
