Filed: 1999-04-19
Abstract: A through-air drying apparatus for drying a traveling wet paper web supported on a continuous fabric comprises a dryer roll about which the fabric and web are partially wrapped and which has a foraminous roll face, a supply hood which surrounds the portion of the roll about which the fabric and web are wrapped and which supplies heated air through the fabric and web and through the roll face into the interior of the roll, and an exhaust system for exhausting air from the roll. An axial exhaust passage is formed through at least one head of the roll. An exhaust manifold is connected to the exhaust passage and defines two outlets on opposite sides of the manifold. A pair of movable ducts are sealingly and releasably engaged with the outlets in the opposite sides of the manifold, the ducts being spaced apart on opposite sides of the roll so that an access space is defined between the two ducts for access to the roll and supply hood. The movable ducts are pivotally connected to fixed ducts by bendable bellows sections of the movable ducts and by hinges, and are actuated to move between open and closed positions by motors and jack screws. The movable ducts pivot about axes parallel to the rotation axis of the dryer roll such that the ducts extend axially beyond the roll by about the same axial extent in both the open and closed positions. The duct system is also suitable for supplying air to the interior of a roll in an outward-flow type of through-air drying apparatus.

IPC: F16H29/12
Filed: 1999-06-02
Abstract: When second rotating bodies are made eccentric, the second rotating bodies move straight in the radial direction along first rotating bodies. Therefore, the cyclically changing angular velocity of the second rotating body changes so that the side on which the angular velocity is higher than the angular velocity of the input-side rotating body and the side on which the angular velocity is lower are symmetrical to each other. Also, on both of the side on which the angular velocity is higher and the side on which it is lower, the acceleration side and the deceleration side change symmetrically to each other. On the other hand, the angular velocity of the second rotating body such that the movement direction with respect to the first rotating body is shifted 180 degrees with each other with the input-side rotating body being the center changes symmetrically with respect to the angular velocity of the input-side rotating body. Moreover, since the second rotating bodies have the same mass, the radial forces of the second rotating bodies are canceled each other, so that the rotational force always acts with the input-side rotating body being the center.

Abstract: For measuring basis weight of a moving web in the cross direction scanner of a paper-making machine, an encapsulated nuclear source of Promethium 147 is used because of its wide area of emission. To conserve space it is mounted on a vertical axis 30 the source moves in a horizontal plane parallel to the moving web from a stowed position where the source is shielded to an active position where the source emits through an aperture, through the moving web, and to a detector. The x-y array planar type detector uses four detector segments symmetrically arranged around a center and compensates for belt direction misalignment (the belt driving the cross direction scanners) by mathematically manipulating the electrical signals from each detector to eliminate the error term.

Title: Wavelength-multiplexing optical transmission channel and optical fiber used therefor
Inventor: TERADA JUN
IPC: G02B6/34
Filed: 1999-03-16
Abstract: A wavelength-multiplexing optical transmission channel having a small wavelength-dependent difference of transmission loss in a 1550 nm band of wavelength and capable of compensating for wavelength dispersion of a single-mode optical fiber. A wavelength-multiplexing optical transmission channel (10) is laid between an optical transmitter (11) and an optical receiver (14).  The wavelength-multiplexing optical transmission channel (10) is composed of a single-mode optical fiber (12) and a dispersion-compensating optical fiber (13) connected in series. Boron is added to at least one of the core and clad of the dispersion-compensating optical fiber (13). Since a boron-added optical fiber is connected to the single-mode optical fiber (12), the dependence of the transmission loss of the wavelength-multiplexing optical transmission channel (10) on the wavelength is low, and the wavelength loss difference of the wavelength-multiplexing optical channel (10) is made flat.

Title: Automated interface generation for computer programs in different environments
Inventor: STEPHENSON JOHN W
IPC: G06F9/44
Filed: 1999-11-22
Abstract: Automated interface generation for computer programs operating in different environments is provided. An automated interface generation system, method, computer program product and article of manufacture is provided comprising an import utility and a runtime environment. The import utility imports a COBOL IMS transaction source file, parses the specified input and output message records, and generates an application programming interface.  The application programming interface operates with the runtime environment to take the data values from the language of a different environment and translate them to a formatted IMS  input message. This format is derived from the definition of the input message record in the COBOL  IMS transaction source file. After the IMS transaction has executed, the resulting IMS output message is translated back to the data values of the language of the different environment, said values including the results of the transaction. The translation step handles data conversion between different code pages, machine architectures, and program semantics, and handles the dynamic nature of IMS messages.

Title: Tunable, mechanically induced long-period fiber grating with enhanced polarizing characteristics
Inventor: SHAW H JOHN
IPC: H01S3/067
Filed: 1999-12-21
Abstract: A new type of fiber filter is useable in optical communication systems. In particular, the fiber filter may be used to flatten the gain of erbium-doped fiber amplifiers (EDFAs). Such gain flattening is important for long-haul, dense (wavelength dependent multiplexed) WDM communication systems. The filter includes a periodic mechanical structure pressed against the side of a single-mode fiber to induce a wavelength-dependent loss in a signal propagating in the fiber core by coupling the signal to fiber cladding modes. The mechanical structure is a periodic comb of small ridges. Each ridge induces a local index change in the fiber via the photoelastic effect. For coupling to the right cladding modes, the period of the grating (and the comb) is in the range of few hundreds of microns. Thus, the grating is easy to fabricate with standard machining equipment. Such filters show low loss (e.g., <0.5 dB) and exhibit the type of filter functions required to flatten the gain of an EDFA. Compared to known photosensitive long-period fiber gratings, which are currently in favor for this application, the filter is simpler and faster to fabricate. The filter does not require capital intensive UV lasers. The filter is adjustable and can be removed easily. The filter is potentially easy to mass-produce. In certain embodiments, the polarization effects caused by asymmetric application of force to polarized light are reduced or eliminated by utilizing a groove to receive the fiber. In alternative embodiments, the polarization effects are enhanced to provide an all-fiber polarizer.
