Title: Attachment and coriolis mass flowmeter with this attachment
Inventor: HUG KUNO
IPC: G01F1/84
Filed: 2004-10-29
Abstract: A description is given of a Coriolis mass flowmeter, with a measuring pipe oscillating in coupled flexural and torsional modes. Mechanically connected to the measuring pipe is an attachment which is formed rotationally symmetrically with respect to an axis of rotational symmetry and can be induced to undergo the torsional oscillations of the measuring pipe. The attachment is a multipart body comprising hollow profile rails and/or beams with a closed hollow cross section. The axis of rotational symmetry of the attachment runs parallel to the straight line (8) (central axis) defined by the centre points (4a, 6a) of the cross-sectional areas (4, 6) of the inlet and outlet of the measured section, or coincide with this line.

Abstract: A method and apparatus for sensing attributes of reflected signals in an optical fiber sensing system is provided. In one embodiment, a method for sensing in an optical fiber sensing system comprising an interrogator couple d to a Bragg grating sensor by an optical cable includes the steps of producing a first optical signal, coupling the first optical signal to an optical cable, receiving a first reflected signal from a Bragg grating sensor within the optical cable, resolving a wavelength of first reflected signal, producing a second optical signal, coupling the second optical signal to the optical cable, receiving a second reflected signal caused by Brillouin backscattering within the optical cable, and resolving a difference in frequencies between the second optical signal and second reflected signal. Embodiments of the method and apparatus are particularly useful for sensing temperature and strain in hazardous locations such as down hole gas and oil field applications and the like.

Patent CA-2490041-A1 (CA)
Title: Wavelength reference system for optical measurements
Inventor: NAKSTAD HILDE
IPC: G01J3/28
Filed: 2004-12-10
Abstract: Devices and methods of accurately determining optical wavelengths, such as the Bragg wavelengths of an FBG sensor array. Wavelength-swept light having a characteristic spectrum is swept over a bandwidth and is applied to an interference filter. The interference filter produces an optical spectrum having one or more reference peaks that are identifiable because of the characteristic spectrum. The optical spectrum is converted into electrical signals having at least one electrical signal that is identifiable because of the characteristic spectrum. The identifiable electrical signal is used by a signal processor as an absolute, high accuracy wavelength reference. Temperature compensation or temperature stabilization can compensate the characteristic wavelength. Fiber Bragg sensor systems can use the wavelength reference to determine the Bragg wavelength of FBG elements. The characteristic spectrum can be imparted by the light source or an optical element such as a transmission line filter.

Title: Paired warp triple layer forming fabric with optimum sheet building characteristics
Inventor: MARTIN CHAD A
IPC: D21F1/00
Filed: 2003-10-07
Abstract: A papermaker's fabric, usable in the forming section of a paper machine, having two layers of cross-machine-direction (CD) yarns. Interwoven with the CD yarns is a system of MD yarns. The MD yarns are grouped into alternating pairs comprising a crossing pair having a first MD yarn and a second MD yarn and a second pair having a third MD yarn and a fourth MD yarn. The first MD  yarn and the second MD yarn combine to weave each CD yarn in the first layer and cross between the first layer and the second layer. The left and right warp yarns in the pairs are aligned in such a way that like adjacent yarns from adjacent pairs have MD cell lengths equal to or less than the MD cell lengths from non-like adjacent yarns from adjacent pairs. The third MD yarn is interwoven with the first layer of CD yarns and the fourth MD yarn is interwoven with the second layer of CD yarns. In this manner, a paired warped triple layer forming fabric may be produced which minimizes drainage and crossover point topographical markings.
