Patent CA-2204370-A1 (CA)
Title: Analyte-controlled liquid delivery device and analyte monitor
Inventor: GROSS JOSEPH
IPC: C12Q1/25
Filed: 1995-10-27
Abstract: A liquid delivery device (40) comprising a housing (41) having a lower surface (51) for application to the skin of a subject and having a reservoir (42) and a gas generation chamber (43) therein separated by a displaceable membrane (45). Gas generated by an electrolytic cell (44) under the control of a microprocessor (46) causes the gas generation chamber (43) to expand and the reservoir (42) to contract, thereby discharging a liquid drug, such as insulin, from the reservoir via a hollow delivery needle (49) extending from the lower surface (51). The delivery needle (49) and a sensor needle (48) both extend from the lower surface a sufficient distance so as to penetrate through the epidermis and into the dermis when the housing is pressed against the skin. The sensor needle (48) has an enzymatic coating for the detection of an analyte, such as glucose in the subject's plasma. The delivery needle (49) is made of platinum-iridium, and a current passes between the needles (48, 49) and a potentiostat circuit (47) according to the amount of glucose detected. A  reference electrode (silver/silver chloride) (50) which rests against the subject's skin increases the accuracy of the glucose measurement. The current through the potentiostat circuit (47) is measured by a voltmeter (53) and a signal from the voltmeter (53) is amplified and communicated to the microprocessor (46) which determines the correct rate of delivery of the drug on the basis of the level of analyte detected in the subject's plasma.

Title: Nickel powder and process for preparing the same
Inventor: NAGASHIMA KAZURO
IPC: B22F1/16
Filed: 1997-09-24
Abstract: A nickel powder having a composite oxide layer comprising lanthanum and nickel and, optionally an oxide of chromium, on at least a part of the surface thereof. The nickel powder is produced by a process comprising the steps of: bringing a solution comprising at least one heat-decomposable nickel compound and at least one heat-decomposable lanthanum compound and, optionally containing at least one heat-decomposable chromium compound, to fine droplets; and heating the droplets at a temperature above the decomposition temperatures of these compounds to prepare a nickel powder and, at the same time, to deposit a composite oxide layer comprising lanthanum and nickel and, when present, chromium oxide, in the vicinity of the surface of the nickel powder. The nickel powder is suitable for use in a conductor paste to be co-fired with unfired ceramic green sheets for a multilayer component or the like because the sintering initiation of the powder is effectively delayed to around the sintering initiation temperature of the ceramic green sheets, thereby preventing the problems caused due to excessive sintering.

Title: Process for preparing amides of n-alkyl polyhydroxyalkyl amines
Inventor: SHERMAN JOSEPH FREDRICH
IPC: C07C233/18
Filed: 1996-05-17
Abstract: N-alkyl polyhydroxy alkyl amines such as N-methyl glucamine having a Gardner Color of less than 1 are reacted with sources of fatty acyl groups such as methyl esters, anhydrides, and/or fatty acids that have greater than 98 %  transmittance at 460 nm in organic hydroxy solvents such as methanol to prepare N-alkyl polyhydroxy amine amides with good color. The N-alkyl polyhydroxyamines can be purified by crystallization, and/or subjected to reductive bleaching, to provide superior color. The reaction is preferably carried out at low temperature for short periods of time and with low catalyst levels to minimize formation of cyclic products. The resulting amide product can be further purified by treatment with anionic and cationic exchange resins to remove soap and amine impurities. The anionic ion exchange resin can be readily regenerated by acidifying it followed by washing with an organic solvent.

Title: Improved correlation processing for motion estimation
Inventor: BORER TIMOTHY JOHN
IPC: G06T7/20
Filed: 1996-07-09
Abstract: Motion correlation is a way of analysing movement in image sequences such as television signals. The estimation of movement in television pictures is essential to enable the use of motion compensated processing techniques. These techniques yield improved quality video processing and moving image compression. Motion correlation would be used as part of a video motion estimation system. This invention describes a number of enhancements to, and a simplfied, efficient implementation of, the basic motion correlation algorithm. It is shown how to produce motion correlation surfaces co-timed with output, rather than input, pictures. It is also shown how to average power spectra to obtain improved noise performance, and hence improved accuracy, in motion correlation. Finally it is shown that separate correlation surfaces can be produced relating to 'future' and 'past' pictures.

Title: Material spreader attachment for mounting on a tractor
Inventor: PATTERSON ROGER L
IPC: A01M7/00
Filed: 1998-02-06
Abstract: A sprayer attachment is designed for mounting upon a swather tractor and includes a central frame with a tank which can be carried upon the front arms of the swather tractor. Two masts each carry a respective one of a pair of booms, each for extending outwardly to a respective side of the tractor for movement with the tractor in a spraying action. Each boom includes an inner section, an outer section and a tip portion. In the folding action the outer section and tip portion are folded about a horizontal axis so as to move to a position overlying the inner section. The folded boom is then pivoted about a vertical axis at the mast to lie along side the side of the tractor. The tip portion includes a parallel cable in advance of the tip portion for impacting an obstacle with the cable actuating release of the latch and accelerating the tip portion away from the obstacle to prevent impact with the obstacle. The tip portion is also moved to the retracted position during the folding action so that the maximum height of the outer section during folding is reduced to avoid contact with power lines and the like. The booms are inclined outwardly and rearwardly in the extended position to move the center of gravity rearwardly.  The tank has two recessed sides to receive the arms of the swather tractor and a front which is inclined forwardly and downwardly to improve vision. Each boom is movable vertically along a vertical supporting mast independently for height adjustment. A hydraulic and electrical coupling allows the existing control lever of the swather tractor to control the boom movement.
