Title: Electrode array made from concave electrodes for meter reading device
Inventor: SMITH EDWARD P
IPC: G08C19/00
Filed: 1990-02-13
Abstract: ELECTRODE ARRAY MADE FROM CONCAVE ELECTRODES          FOR METER READING DEVICE                      ABSTRACT    An electrode array for use in an apparatus for remotely monitoring the position of a rotatable member as the rotatable member is rotated by an axle about an axis.  The array includes a substrate composed of a three-layer compos-ite having first and second surfaces, a plurality of spaced-apart, excitable electrodes defining a center portion disposed on the first surface, an aperture in the substrate located in the center portion for receiving the axle, a center electrode in the center portion spaced apart from the axle circumscribing the aperture, a guard composed of a first conductive strip disposed in the center portion on the first surface spaced apart from and located between the spaced apart excitable electrodes and the center electrode.        Each of the excitable electrodes have a concave free edge that delimits a part of the center portion.  The excitable electrodes and the meter hand have predetermined areas, so that the area of any given member of the excitable elec-trodes subtended by the meter is substantially constant as the meter hand traverses across such electrode.     112089.PA: Electrode Array Made from Concave Electrodes for Meter Reading Device    Edward P.

Title: Helicopter, high rotor speed enhancement
Inventor: WALSH DAVID M
IPC: G05D1/08
Filed: 1990-04-27
Abstract: A helicopter engine speed reference (66) is increased (113, 103-105) in response to heavy rotor larding (108). The reference speed is faded up (113, 104) at a rather rapid rate to 107% of rated speed (114). After a fixed time interval (118), reduced rotor loading (119) will cause the reference speed to be faded down slowly (120, 103-105) to rated speed (121). If torque exceeds 111% of rated torque (117), the reference speed is similarly faded down. (120, 103-105).
Patent CA-2016499-A1 (CA)
Inventor: MIKI YUJI
IPC: C22B9/02
Filed: 1990-05-10
Abstract: A method of removing non-metallic inclusions from a molten metal by allowing the molten metal to pass through at least first and second vessels which are intermediate between a ladle and a mold.   The molten metal is made to stay in the vessel for a period not shorter than 40 seconds while a horizontal rotation is imparted to the molten metal in the first vessel.  The molten metal is then transferred from the first vessel to the second vessel.  The molten metal in the second vessel is then heated.  This method is suitably carried out by an apparatus comprising a first vessel having a discharge opening at its bottom and surrounded by a rotational magnetic field generating device for centrifugation of the molten metal in the first vessel, and a second vessel for receiving the molten metal discharged from the first vessel and provided with a heating device for heating the molten metal received therein.
Patent CA-2016615-A1 (CA)
IPC: H04J3/06
Filed: 1990-05-11
Abstract: A filtering algorithm for the SONET H4 byte is implemented with circuitry including an internal H4 counter which is incremented each frame and is locked to a received H4 byte once every 24 frames if a proper bit sequence is detected in a designated frame.  If the designated bit sequence is not detected, the counter is not reset and continues to be incremented.  If parity errors are detected, the counter is not reset and is allowed to free run to simulate the appropriate H4 byte input.

IPC: A61N1/05
Filed: 1990-10-03
Abstract: Électrode de défibrillation destiné à l'implantation sur ou dans la région du coeur d'un patient et relié à système de défibrillation. L'électrode comporte une pluralité d'éléments conducteurs d'électricité qui, espacés et interconnectés, ont pour effet d'augmenter le nombre de points de décharge sur l'électrode. Dans une première version de l'invention, l'électrode comporte une pluralité de cercles conducteurs concentriques qui sont interconnectés. Dans une deuxième version de l'invention, l'électrode comporte une pluralité d'éléments électriques conducteurs planaires qui sont interconnectés dans une configuration rappelant un casse-tête. Dans une troisième version de l'invention, l'électrode comporte des fils conducteurs enroulés autour d'un cathéter intracardiaque. Dans une quatrième version de l'invention, des fils conducteurs sont enroulés dans une configuration de spirale concentrique. Dans une cinquième version spécifique de l'invention, la partie distal d'un cathéter intracardiaque comporte une pluralité de sites conducteurs isolés. Dans toutes les version indiquées ci-dessus, la décharge d'énergie électrique de l'électrode à la surface du coeur se fait par tous les points de décharge des composants conducteurs. Le nombre accru de points de décharge assure donc une distribution plus uniforme de l'énergie vers le coeur. En outre, pour une efficacité plus grande encore, chacune des configurations proposées peut être fabriquée sans support isolant.

Title: Method for immunochemical determination of hapten
Inventor: ITO MICHIO
IPC: G01N33/53
Filed: 1990-10-05
Abstract: ABSTRACT OF THE DISCLOSURE:           A method for immunochemical determination of a hapten in a sample is disclosed, in which (A) a high-molecular compound to which the hapten is bound (reagent A), (B) insoluble carrier particles carrying thereon an antibody to the hapten (reagent B), and (C) magnetic substance-containing insoluble carrier particles carrying thereon an antibody to an antigenic determinant in the high-molecular compound and different from the hapten (reagent C), are used. These three reagents are dispersed in the sample, then, a magnetic field is applied to separate from the reaction mixture unreacted reagent (C) and agglutinated particles formed from the reagent (B) and the reagent (C) through the reagent (A). The amount of the reagent (B) remaining dispersed in the reaction mixture is measured, thereby determining the extent of competitive inhibition to the agglutination of the reagent (B) and the reagent (C) through the reagent (A) by the reaction between the hapten in the sample and the reagent (B). The method of the present invention requires no troublesome operations such as separation-washing and is free from any problem in safety. By the method of the present invention, the concentration of a hapten in a sample is determined by simple operations in a short time and with high sensitivity.
