Granted: 2007-06-19
Abstract: A random fiber web (W) with a uniformly distributed sorbent particles (P) is described. In order to provide a uniform distribution of the sorbent particles (P) within the random fiber web (W), it is proposed to combine the sorbent particles (P) and fibers (F) in the web (W) during its formation. The fibers (F) are joined in such a way that the sorbent particles (P) are secured within the web (W) in a uniform distribution. The fibers (F) are joined with the use of dry adhesives, UV hardenable adhesives, low melting fibers, spraying a liquid adhesive or needling. The invention extends to a machine for making random fiber webs (W) and a method of making a thin bed filter for removing odors and particulates.

Abstract: Plurality of channel waveguides of an arrayed waveguide diffraction grating are arranged such that all of intervals thereof are not constant between each two adjacent channel waveguides at a first coupling portion for coupling an input slub waveguide and the arrayed waveguide diffraction grating and a second coupling portion for coupling an output slub waveguide and the arrayed waveguide diffraction grating.      Further, the plurality of channel waveguides of the arrayed waveguide diffraction grating are arranged such that all of length differences thereof are not constant between each two adjacent channel waveguides. For example, one of the channel waveguides is deleted, so that a length difference of adjacent channel waveguides is determined to be larger than that of the other two adjacent waveguides. According to this structure, it is possible to provide an optical waveguide multiplexer/demultiplexer in which an insertion loss property becomes flat in all wavelength ranges and the insertion loss characteristics are not fluctuated by the fluctuation of the wavelength.

Abstract: The present invention provides a postage metering system that includes a plurality of closed and open meter printer modules operatively connected as part of a metering network. A single postal security device (PSD) is coupled to the network, either directly, through a personal computer or through one of the printer modules. The PSD includes unique identification and the ability to store postal value and generate digital signatures. The printer modules function as a postage metering network wherein a printer module requests evidence of postage payment from the PSD for concluding a postage metering transaction. The printer module initiates the postage metering transaction in the PSD by sending a request for evidence of postage payment to the PSD. The PSD receives the request and sends the evidence of payment to the printer module for subsequent printing.
