Title: Dual loop coriolis effect mass flowmeter
Inventor: LISTER ERNEST DALE
IPC: G01F1/84
Filed: 1998-02-25
Abstract: An apparatus for measuring the flow rate of a fluid flowing through a minimal flow pipeline with a Coriolis effect mass flowmeter. The flowmeter has a single flow tube with two loops. The loops are connected by a cross-over section. A driver oscillates the loops and the phase difference between the ends of the loops is measured. The measured phase difference is then used to find the flow rate of the fluid. The flow tube is fixedly attached to an anchor which is, in turn, attached to a housing. The anchor separate the vibrating, dynamic portion of the flowmeter from the non-vibrating portion of the flowmeter.

IPC: H04L49/111
Filed: 1998-03-18
Abstract: A self-routing switch such as a Banyan switch has a controller which recognises incoming routing requests which would give rise to blocking in the switch and makes an optimum selection of queued requests which can be handled without blocking. The controller is implemented by means of an optical neural network having a light source array (14) to illuminate a photodetector array (26) through a mask (15), there being a light source array element (20) and a photodetector element (27) for each possible path through the switch. The assignment of paths to array locations is such that, for the path corresponding to any light source array element, the photodetector array element positions corresponding to the paths blocked thereby form a pattern which is a shifted version of the pattern formed by the photodetector array elements corresponding to the paths blocked by a path corresponding to any other light source array element, whereby a single mask may be employed.

Patent CA-2300005-A1 (CA)
Inventor: LAUTERBACH GARY
IPC: G06F15/177
Filed: 2000-03-06
Abstract: A pending tag system and method to maintain data coherence in a processing node during pending transactions in a transaction pipeline. A pending tag storage unit may be coupled to a cache controller and configured to store pending tags each indicative of a coherence state for a data line corresponding to a pending transaction within the transaction pipeline. The pending tag storage unit includes a total amount of storage which is substantially less than an amount required to store tags contained in the full tag array for the cache memory. When a pending tag exists in the pending tag storage unit, the coherence state of the corresponding data line within the cache memory is dictated by the pending tag for snoop operations. Accordingly, data coherence is maintained during the period when transactions are pending, e.g., not yet presented to a processor and cache. When a pending transaction is completed, the coherence state of the corresponding data line as indicated by the full tag array may be overwritten by the coherence state as indicated by the pending tag and the pending tag may deleted from the pending tag storage.

Abstract: In a communications system including a plurality of base stations, each of which is employed to communicate with a corresponding geographic sector, a method of assigning N transmission channels, each channel having a corresponding channel number, to be used by the plurality of base stations. In the method, a set of N random numbers is generated. Each random number corresponds to a channel number. The set of random numbers is partitioned into a plurality of sectors, each of the sectors corresponding to a geographic region serviced by one of the plurality of base stations. Based upon the partitioned set of random numbers, corresponding channels are assigned for use by each one of the base stations. According to one embodiment, two channel numbers in the same sector are separated into different sectors if the difference between the two channels numbers is equal to or less than a predetermined number. When the predetermined number is one, two consecutive channel numbers are separated.

Title: Sample detection to initiate timing of an electrochemical assay
Inventor: TEODORCZYK MARIA
IPC: C12Q1/54
Filed: 2000-06-13
Abstract: An electrochemical assay includes a method for determining with great accuracy the time at which an applied sample bridges a gap between the electrodes of an electrochemical cell. The method involves applying a constant small current across the gap, while monitoring the potential difference between the electrodes. The time at which the sample bridges the gap is marked by a sharp drop in the potential. A constant voltage is applied after the sample is detected, and the current and/or charge through the sample is monitored over a period of time. From the measured current or charge, the analyte concentration of interest can be calculated.

Abstract: L'invention concerne un réacteur reformeur (10) pour la production de gaz riche en hydrogène, qui comprend des première, deuxième, troisième et quatrième zones (18, 20, 22, 24) et un espace de collecte de produit gazeux (40). Les zones sont adjacentes, en séquence. Un trajet d'écoulement P1 assure l'écoulement d'un flux de réaction dans des directions divergentes, depuis la première zone (18) vers la seconde zone (20), l'écoulement se poursuivant dans les mêmes directions générales divergentes via les deuxième, troisième et quatrième zones (20, 22, 24). L'établissement de ces directions divergentes permet l'entrée et le passage dans une zone sur une étendue supérieure à celle qui correspond à une géométrie de section transversale unique de la zone, ou bien à une section transversale unique du flux, par rapport au sens d'écoulement. On peut utiliser une telle configuration pour abaisser la pression d'écoulement du flux de réaction, de manière à réduire les aménagements du réacteur contre les éléments parasites, et aussi pour augmenter le débit du réacteur.

IPC: A01B63/22
Filed: 2000-10-06
Abstract: Lift wheel structure for an implement includes four bar linkage having a curved lower link connected to the frame closely adjacent a first tool-carrying rank. A  caster wheel is supported at the forward end of the linkage for castering in an accommodation area defined by the curved lower link. Plates are bolted to the sides of the lower link and extend along sides of an upper link to a connection with a lift cylinder directly above the upper link. The link and the cylinder closely overlie the frame to limit interference with other components mounted above the frame and to facilitate compact folding of implement sections. Loads, including cylinder lift loads, are transmitted primarily through the lower link. A protected transducer assembly is connected between the lower link and the frame to maximize and linearize transducer response in the depth control range. The lift wheel structure can by mounted at different locations on the frame to accommodate different tool configurations and provide the desired automatic depth control and leveling functions. In one embodiment a tension link connects a forward four bar linkage wheel structure with a rear single pivot lift wheel structure such that level lift is provided.
