Patent GB-2312750-A (GB)
Title: Differential pH measurement apparatus
Inventor: LUZZANA MASSIMO
IPC: G01N27/416
Filed: 1996-05-02
Abstract: An apparatus and method to measure the concentration of certain chemical substances in clear, turbid or colored solutions, suspensions or emulsions by two micro pH electrodes connected in series with microbore tubing. Sampling is made by a microdialysis fiber or by dilution in a mixing chamber with specifically formulated buffer systems. The reaction of interest can be started by chemically immobilized or physically confined reagents in a reactor tubing interposed between the two pH electrodes, or by standard mixing techniques. The concentration of an analyte is calculated from the formula: <MATH> where FCAL is a calibration factor experimentally determined and DeltapH0, DeltapH1, are the difference in pH before and after a given chemical reaction producing or absorbing protons has occurred. Substances like glucose, fructose, sucrose, lactate, ascorbate, citrate, acetate, malate, CO2, bicarbonate, creatinine, urea, triglicerides, proteins, enzymes (lypases, proteases, cholinesterases, Glucose-6-Phosphate -dehydrogenase (G6PD), alkaline phosphatase, urease and others) or enzyme inhibiting substances such as antibiotics and organophosphorous pesticides can be rapidly detected in body fluids, hemodialysis ultrafiltrate, milk, beverages (wine, beer, vegetable juices), surface and waste waters, cell suspensions and the like. <IMAGE>

Title: A programmable digital low pass filter for magnetic resonance imaging
Inventor: HOENNINGER III JOHN C
IPC: A61B5/055
Filed: 1996-10-11
Abstract: The coefficients of the first FIR filter stage of a synchronised multirate digital filter are loaded from a local coefficient memory 196,197 which stores the coefficients required to implement a large number of different filter characteristics. This allows rapid selection of filter characteristics, for example between echoes or signal samples. The coefficient memory for each of the I and Q channel DSP processors 178,180 is initially written by a host computer. The order of the first stage, its coefficients, and its decimation factor are all programmable. The use of a second or third stage may be selected.

Title: Preparation of acetic acid and/or methyl acetate by a carbonylation reaction
Inventor: DENIS PHILIPPE
IPC: C07C67/36
Filed: 1997-07-10
Abstract: The present invention relates to the preparation of acetic acid and/or methyl acetate by carbonylation of methanol in the presence of carbon monoxide and in the presence of iridium and optionally rhodium. The reaction is carried out in an installation comprising notably a first zone which is a principal carbonylation reactor, a second in which the reaction mixture is partially vaporised. According to the invention, the carbon monoxide present in the reaction mixture is consumed by introducing said reaction mixture into an additional reactor situated between the principal carbonylation reactor and the zone in which the reaction mixture is partially vaporised. In this way the loss of carbon monoxide from the carbonylation reaction system may be reduced.
Patent GB-2316245-A (GB)
Title: Fluorescent lamp starter circuit
Inventor: GYOTEN MASAYOSHI
IPC: H05B41/18
Filed: 1997-07-29
Abstract: A fluorescent lamp starter circuit 7 is applicable to ballasts 2 and lamps 3 having different normal rated power. The circuit 7 includes a control circuit 16 which is responsive to a first timer circuit 11 for turning an FET 9 on to pass warm-up current through the lamp filaments 4, 5 for a predetermined time which is not dependent on the lamp and ballast nominal power rating. When the AC supply 1 is initially connected, a capacitor 15 in timer 11 charges until it reaches a voltage sufficient to turn on a zener diode 22, resulting in turn off of an transistor 25, turn on of a transistor 21 and thus turn on of FET 9. The voltage drop across FET 9 and series resistor 10, due to the warm-up current, is lower than the zener voltage of zener diode 13 so that capacitor 15 discharges during conduction of FET 9. After a predetermined period of conduction of FET 9, the voltage on capacitor 15 drops below the zener voltage of a zener diode 23 which therefore turns off resulting in turn off of transistor 21 and FET 9 and generation of a kick voltage for lamp starting by ballast inductor 2. If the lamp fails to start, the starting sequence is repeated. If the lamp turns off due to a fall in the AC supply voltage, the circuit 7 automatically restarts the lamp 3. If the lamp fails to start after repeated attempts, a capacitor 19 in a second timer circuit 17 will eventually charge to a voltage sufficient to hold transistor 25 on. The starting circuit is then held in a state with transistors 21 and 25 on and FET 9 off, thereby protecting FET 9 from overheating due to prolonged current flow therethrough.

Fuel gas, for example methane from a supply 26 is fed via path 28 to an inlet manifold 30 supplying all the anode passages 14a and 14b in which a reforming reaction takes place. Anode exhaust gas from the outlet manifold 48b is supplied to the inlet manifold 30 to mix with the fuel gas to the anode passages. Oxidising gas such as air is fed via path 38 to an inlet manifold 40 supplying all the cathode passages 16a and 16b.

Title: Characterising oil well effluents by attentuation of gamma rays of two energy levels
Inventor: CHEVALIER PHILLIPE
IPC: G01N23/12
Filed: 1998-05-19
Abstract: Oil borehole effluents, formed by a multiphase fluid mixture typically containing oil, water and gas, are characterised by measuring their gamma ray attenuation at energy levels of about 100 keV and about 40 keV. A gadolinium 153 source (20) is used to produce gamma rays of both energy levels. The source (20) and a detector (21) are placed on opposite sides of a Venturi throat (12) and the density of the effluent is determined from the attenuations at the two energies. A pressure sensor (15) measures the pressure difference between two pressure takeoffs (16 and 17) upstream and in the throat of the venturi. The pressure drop and the density values are used to determine the mass flow of the effluent. A temperature sensor (23,24) and an absolute pressure sensor (22) may be provided.

Title: Modular Marine Articulated Transportation Vessel
Inventor: EDWARDS DAVID LINDSAY
IPC: B63B35/66
Filed: 1999-03-04
Abstract: An articulated modular and integrated marine vessel has a potentially stand-alone prime mover 1 to which subsequent cargo units 2,3 may be sequentially connected and disconnected at will. Variability in marine displacement about the articulated joints 4 is provided by ratchets 5. Ratcheting allows for said connection and disconnection of modular units. Modularity provides for jettisoning of cargo units in certain hazardous situations, improves structural stability of the vessel with respect to length, reduces the turning circle and hence the stopping distance. The articulation provides for the transmission of forces both tensile and compressive between connected units such that the vessel behaves and moves as a united entity.
