Patent CA-2329100-A1 (CA)
Inventor: DOLMAN GRAHAM
IPC: H03F1/32
Filed: 2000-12-20
Abstract: This invention relates to a phase and amplitude detector (160) required to identify small signal errors in a signal envelope having a large dynamic range, especially in the content of linearization of a power amplifier (122) arrangement employing a pre-distortion technique. A vector generator (300, 352, 372) responsive to a reference signal R (110) produces a frame of reference vectors R1-Rn (274-280) generated by a combination of the reference signal R (110) with first A (270) and P(272) offset vectors that provide an amplitude and phase displacement of the reference signal R (110). A signal combiner (290-296, 360-366, 390 396) is arranged to generate difference vectors E1-En by combining the frame of reference vectors R1-Rn (274-280) and the feedback signal F (124, 150), with the difference vectors E1-En expressing the phase (p, 254) and the gain (a, 252) error terms relative to the reference signal R  (110) and the first A (270) and second P (272) offset vectors. An error signal detector, (330-336) responsive to the difference vectors E1-En and arranged to provide a measure of the phase (p1 254) and the gain (a, 252) error terms, provides signal amplitudes that can be combined to generate error signals (182 (Y), 184. X)).      The error signals take the general form:      X = P1 - P2 - P3 + P4 = -8PpR:      Y = P1 + P2 - P3 - P4 = -8AaR

Title: Method of and apparatus for contactless planarity measurements on ferromagnetic metal strip
Inventor: SONNTAG STEFAN
IPC: G01B7/34
Filed: 2001-01-11
Abstract: A method and apparatus for the contactless determination of planarity of a ferromagnetic metal strip during transit of the strip through a strip-processing line or cold-rolling line. Hysteresis loops are repetitively impressed in the metal strip and the tangential magnetic field strength is measured at a surface of the strip and electromagnetic parameters are determined from the time course of the tangential field strength signal. The parameters are functions of the mechanical stress which is evaluated to determine residual intrinsic stress distribution and then the planarity or nonplanarity of the strip.

Title: Sealing device for segmented stator ring
Inventor: TREMAINE ERIC
IPC: F01D11/00
Filed: 1999-10-01
Abstract: The invention provides a novel sealing device and plenum assembly particularly adapted for forming a plenum inwardly of a circumferential stator blade array in a gas turbine engine. A gas turbine engine has an air compressor, combustor, and an annular hot gas path axially ducting hot gas past a circumferentially spaced apart array of stator blades upstream of a turbine rotor. Each stator blade has an internal bore for ducting cooling air between a radially outward shroud and a T.O.B.I. plenum (i.e.;      Tangential On Board Injection) that accumulates cooling air for expulsion through T.O.B.I. nozzles.      The T.O.B.I, plenum is defined by: a forward plate; a rearward plate; and an inner shroud disposed between the forward and rearward plates. The inventive improvement relates to a novel sealing device permitting construction of an inner shroud comprising a circumferential assembly of inner shroud segments with radially extending joints between adjacent inner shroud segments. The outer shroud is a one-piece hoop integral wiht stator blades and segmented inner shroud. To assemble the inner shroud to contain compressed air in the T.O.B.I. plenum, the plenum enclossure includes releasable elongate fasteners engaging the forward and rearward plates and clamping the inner shroud segments between the plates. Each fastener is disposed axially within an associated joint between adjacent inner shroud segments and each fastener includes a sealing sheath disposed about the fastener for sealing the associated joint.

Patent CA-2351042-A1 (CA)
Inventor: PIATT MICHAEL J
IPC: H04N1/405
Filed: 2001-06-19
Abstract: The present invention addresses problems encountered in the conversion of continuous tone data into binary data for printing on low resolution imaging systems. Representation of the continuous tone data is only roughly approximated through the conversion to binary data. Artifacts of the binary printing process are objectionable for several reasons. They decrease over all image quality and may sometimes allow for only partial representation of the original data. Partially formed and/or irregularly formed text characters are one such example. This invention addresses this problem by forcing certain levels to be processed through predictable dot dispersion patterns so as to preserve pre-identified portions of the input data stream.   Continuous tone image data for imaging on a digital output device is processed by identifying at least one problematic tone level in the binary representation of the image, and identifying at least one non-problematic tone level in the binary representation of the image. Data transformation is then applied to cause the digital output device to replace the at least one problematic tone level in the binary representation of the image with output at the at least one non-problematic tone level in the binary representation of the image.

Abstract: La présente invention concerne un procédé permettant de payer des gains à un jeu de hasard de casino tel que la roulette. Selon ce procédé, le casino affiche sur un écran informatique les mises du joueur que le croupier utilise conventionnellement pour un calcul mental des gains à payer. Toutefois, le croupier intervient désormais en spécifiant au clavier, ou à tout autre instrument analogue, les mises qu'a faites le joueur, ce qui lui permet d'obtenir automatiquement les montants des gains à payer au joueur. L'écran informatique du joueur affiche également le montant total à payer tel qu'il est calculé. En outre, l'organe de saisie des données comporte un écran que le croupier peut lire sans quitter la table des yeux. Cet écran permet au croupier de vérifier l'exactitude des mises saisies et le gain total payé tout en continuant à surveiller la table pour que les mises ne sont pas déplacées après la clôture des mises. Enfin, les joueurs peuvent facilement surveiller l'écran informatique du joueur pour vérifier que le paiement des gains se fait correctement.

Title: Benzylic halogenation of alkylbenzoic acid esters
Inventor: ELNAGAR HASSAN Y
IPC: C07C67/307
Filed: 2000-03-10
Abstract: Direct preparation of benzylically halogenated alkylbenzoic acid ester from an alkylbenzoic acid ester in which the alkyl group is a primary or secondary alkyl group is carried out. The ester group of the starting ester (i) is devoid of non-aromatic unsaturation and (ii) if an aromatic group, is devoid  of ring substitution that would undergo benzylic halogenation. The process comprises slowly feeding halogen continuously and/or intermittently to an agitated solution of the alkylbenzoic acid ester in a liquid halogen- containing solvent maintained at a thermal halogenation temperature such tha t when the alkyl group of the alkylbenzoic acid ester is a primary alkyl group  and monohalogenation is desired, the total amount of halogen fed does not exceed about 0.8 mole of halogen per mole of alkylbenzoic acid ester. If the  alkylbenzoic acid ester is a toluic acid ester and dihalogenation is desired , the amount of halogen fed is over (1) mole but no more than about 1.8 moles per mole of the toluic acid ester. Ester cleavage is minimized and other advantages are made possible.
