Abstract: The present invention is directed to a papermakers fabric which provides for usage of high aspect ratio yarns as structured weave components. The fabric comprises a system of flat monofilament machine direction yarns (hereinafter MD yarns) which are woven in a selected weave construction which provides stability to the fabric. In a preferred embodiment, the system of MD yarns comprises upper and lower yarns which are vertically stacked. Preferably, the upper MD yarns define floats on the upper surface of the fabric and each upper MD yarn is paired in a vertically stacked orientation with a lower MD yarn. the lower MD yarns may weave in an inverted image of the upper MD yarns to provide floats on the bottom fabric surface or may weave with a different repeat to provide a different surface on the bottom of the fabric.             At least the upper MD yarns are flat monofilament yarns woven contiguous with each other to reduce the permeability of the fabric and to lock in the machine direction alignment of the stacking pairs of MD yarns. In the preferred embodiment, the same type and size yarns are used throughout the machine direction yarn system and both the top and the bottom MD yarns weave contiguously with adjacent top and bottom MD yarns, respectively. The stacked, contiguous woven machine direction system provides stability and permits the MD yarns to have a relatively high aspect ratio, cross-sectional width to height, of greater than 3:1.

Granted: 2000-08-15
Abstract: A message and billing system and method is provided for transmitting a reply message over a communications network from a called party's message service system to a calling party's message service system. Prior to transmitting a message to a called party, a calling party's message service system prompts the calling party to specify whether a prepaid reply is authorized. Based upon the calling party's response to the prompt, the calling party's message service system generates a message file associated with the message, which includes a prepaid reply field indicating whether a prepaid reply was authorized by the calling party. The message file is transmitted over a communications network to the called party's message service system and the called party's message service system identifies whether a prepaid reply had been authorized by the calling party based upon the prepaid reply field of the message file. Upon the called party's transmission of a reply message to the calling party's original message, the called party's message service system generates a reply message detail record having a prepaid reply field indicating whether the calling party had authorized a prepaid reply. When the prepaid reply field of the reply message detail record indicates that the calling party authorized a prepaid reply, the calling party is charged a fee for the transmission of the reply message. Alternatively, when the prepaid reply field of the reply message detail record indicates that the calling party had not authorized a prepaid reply, the called party is charged a fee for the transmission of the reply message.

Abstract: The improved creped non-laminar singular web structure comprising long fibers and short fibers demonstrated by high TWA and Z  peeling. Creping causes a certain portion of long synthetic fibers and short fibers to substantially be oriented in a predetermined vertical or Z  direction across the thickness of the web structure. In particular, when a stratified preparation containing wet stiff CTMP fibers is used, the vertically oriented CTMP fibers increase the total water absorption (TWA) of the web structure without collapsing. The high TWA print/double-creped paper products manufactured from the above web structure are suitable for heavy wipe and dry uses.

Abstract: A variable pitch fan in which the pitch of the fan blades is varied under control of a controller according to the speed of the fan. The controller is programmed to respond to increased fan speed by decreasing pitch of the fan blades. The variable pitch fan has a piston extending axially from a main shaft, about which main shaft a fan blade hub rotates. A pitch shifter is mounted on a cylinder, which itself is mounted on the piston. The pitch shifter is actuated by hydraulic fluid supplied through the main shaft to the cylinder. The piston is preferably axially stationary in relation to the main shaft. The cylinder is secured against rotational movement by at least one guide pin passing into the main shaft. Grease for the pitch shifter is supplied through the guide pin. One guide pin may be used for grease supply, while another may be used for excess grease return. Cooling of a pitch shifter may be accomplished using a heat sink mounted within the fan hub, preferably in a fan configuration, to conduct heat away from the cylinder into air rotating within the fan hub. Counterweights are mounted on each fan blade of a variable pitch fan, preferably hydraulically actuated, in a position which generates a torque opposite in direction to torque generated by the fan blades. The counterweights may be overbalanced, underbalanced, or balanced.

Abstract: There is described a three-dimensional imaging system for acquiring a succession of two-dimensional images of a target volume represented by an array of pixels and transforming the succession of two-dimensional images directly into a three-dimensional image.       Generally, the system comprises a scanner, a memory and a transformation means. The scanner scans the target volume using an angular scanning technique, and generates a succession of digitized two-dimensional images thereof representing cross sections of the to rget volume on a plurality of planes spaced around an axis of rotation of the scanner. The memory stores the succession of digitized two-dimensional images and a data set.      The data set comprises: (i) calibration parameters defining the geometric relationship between successive digitized two-dimensional images; and (ii) acquisition parameters defining the geometric and orientational relationship between successive digitized two-dimensional images. The transformation means receives the digitized two-dimensional image and the data set, and transforms the digitized two-dimensional images directly into a three-dimensional image of at least a portion of the target volume. The system is particularly suited to display a three-dimensional image from two-dimensional images which are acquired by a fan- or axially-acquired ultrasound image data.
