Title: Reagent and process for the enzymatic determination of glucose
IPC: G01N33/66
Filed: 1973-08-20
Abstract: 1395306 Enzymatic determination of glucose MERCK PATENT GmbH 20 Aug 1973 [28 Sept 1972] 39282/73 Heading GIB  A method of determining glucose comprises (a) treating the glucose with glucose dehydrogenase in a buffer at pH6.5-8.5, (b) allowing hydrogen produced in this reaction to reduce a pyridine coenzyme and (c) determining the amount of reduced pyridine coenzyme so produced. The method is applicable to whole blood, blood serum, urine and honey. Protein is first removed from the sample by treatment with trichloroacetic acid or perchloric acid. Any alpha-glucose is converted to beta-glucose with a mutarotation accelerating enzyme, e.g. mutarotase. Buffers specified include phosphate, citrate and "tris" buffer (trishydroxymethylaminomethane). The buffer may contain an alkali metal salt, e.g. sodium chloride, to stabilize the glucose dehydrogenase and an inhibitor for oxidases which attack the reduced pyridine coenzyme, e.g. 3-acetyl quinoline, sulphosalicylic acid, m-hydroxybenzoic acid, salicylic acid, acetyl salicylic acid, salicylamide, 1-(p-chlorophenylsulphonyl)-3-propylurea, nicotinic acid, nicotinamide, quinaldic acid, quinolyl-2-chloromethane, caffeine, uric acid, theophylline, desoxy-guanosine, inosin or xanthosine. The pyridine coenzyme may be nicotinamide-adenine-dinucleotide or nicotimamide-adenine-dinucleotide-phosphate. The reduced pyridine coenzyme may be determined directly by its U.V.-fluorescences or by its colour reaction with a tetrazolium salt in the presence of diaphorase. Reagents used in the process may be absorbed on filter paper mounted on plastic strips. A test kit may contain all reagents necessary for the determination.

Patent GB-1098965-A (GB)
Title: A process for the polymerization of lactones
IPC: C08G63/82
Filed: 1966-09-05
Abstract: In a process for the catalytic polymerization of a lactone in the presence of an inert liquid diluent in which both the monomer and polymer are insoluble (or substantially so), the polymerizing monomer is present as a mobile discontinuous phase in the diluent and the movement of the diluent phase and the polymerizing phase relative to each other is mainly due to the difference in the specific gravities of the two phases. Preferably polymerization is effected by passing a stream of drops into the diluent whereby the drops move upwardly or downwardly through the diluent.  The drops are preferably 0.5 to 6.0 mm. in size.  The diluent may itself be in motion and may be removed from the reaction vessel and recycled, possibly after cooling.  The polymer may be separated from the diluent by filtration or centrifugation (particularly if its specific gravity is about the same as that of the diluent) but the two phases are preferably allowed to separate under gravity.  Preferred lactones are alpha, alpha-dialkyl-beta propolactones.  Preferred diluents are viscous paraffinic oils having a viscosity of at least 3 centistokes at the polymerization temperature used.  Preferred catalysts are amines, quaternary ammonium compounds, tertiary phosphines, quaternary phosphonium compounds, compounds of arsenic, antimony and bismuth and compounds containing carboxylate ions.  Examples describe the polymerization of (1) alpha, alpha-dimethyl-beta-propiolactone, (2) alpha-methyl-alpha-ethyl-beta-propiolactone.

Title: Improvements in or relating to magnetic recording apparatus
IPC: G11B5/49
Filed: 1959-11-24
Abstract: 862,632. Magnetic recording. INTERNATIONAL BUSINESS MACHINES CORPORATION. Nov. 24, 1959 [Nov. 26, 1958], No. 39929/59. Class 40 (2). [Also in Group XIX] A magnetic recording apparatus comprises a magnetic head 10, a D.C. source connected to the head, supplying a normally continuous current, and an AND circuit A (including a pair of input terminals) said circuit being connected to the source, and operable to interrupt the D.C. supply to the head whenever both terminals are simultaneously energized. Both terminals are so energized, when a digit is to be recorded on the magnetic recording surface 11 of e.g. a drum 12, and a discrete identifiable variation in recorded flux is produced. A conductor 20 supplies a binary " data " signal, in which a higher e.g. positive, level represents a bit 1 and a lower e.g. negative level represents 0. A conductor 21 provides a positive " gate " pulse when a gate circuit (not shown) is open and a negative pulse when it is closed. The " data " signal is applied to inverter I whereby a bit " 1 " appears on line 25 as a more negative signal than " 0." Both this signal and the " gate " pulse are applied to the AND circuit A. An output pulse is only produced when both " gate " and " data " signals are present at its input. When the output of inverter I is " negative," a current driver CD is cut off, whilst a " negative " signal at the input of the inverter permits head 10 to record a continuous signal. An explanation of the possible mechanism of the recording process itself is given in the Specification.

The operating temperature may be below 500‹ C. Treatment is described of a solution and a slurry simulating those obtained in the processing of aluminium- and zirconiumclad nuclear fuel elements. Hydrocarbon fuels referred to are kerosene and diesel oil. If air containing added oxygen is used as the fluidizing gas, the velocity of the gas may be reduced to prevent elutriation of the bed solids.
Patent GB-949392-A (GB)
Title: Desulphurisation of hydrocarbon materials
IPC: C10G53/14
Filed: 1960-11-22
Abstract: Sulphur-containing hydrocarbon material, for example petroleum fractions, are desulphurized by submitting the material to a selective oxidation step in which the sulphur-containing compounds are selectively attacked, and then subjecting the oxidized material to a thermal decomposition step in which the sulphur is eliminated as a sulphurous gas, normally SO2 or H2S. The oxidation may be effected by organic or inorganic peroxides, hydroperoxides, organic and inorganic peracids, chlorine, nitrogen oxides, ozone, or air or oxygen, which last may be promoted, for example by metals, salts, or oxides of Groups Va and VIII of the Periodic Table, especially Pt, Pd, Ni and V, which may be supported on soda-lime, active carbon or alumina, which last may have its acid properties modified by treatment with an alkali metal or ammonium compound. Preferred oxidation conditions are 80-180 DEG  C. for 1/2 -20 hours, using between 1 and 6 active oxygen atoms per atom of feedstock sulphur. The thermal decomposition step may be carried out for 1/2 -5 hours at above 200 DEG  C., especially between 300 DEG  and 400 DEG  C., and an inert carrier gas, for example nitrogen. may be passed through the reaction mixture, This step may be promoted by porous solids having acidic or basic properties, for example ferric oxide on alumina, bauxite, thoria on pumice, silica-alumina, soda-lime, or acid sodium phosphate on carbon.

Abstract: 889,855. Cathode-ray tube circuits. FERNSEH G.m.b.H. Nov. 25, 1960 [Nov. 25, 1959], No. 40575/60. Class 40(7). [Also in Group XL(b)] Output signals from a vidicon pick-up tube 1 which, due to excessive illumination, would exceed a predetermined maximum level with respect to the level set by a clamp circuit 8, cause a transistor 10 to conduct and the resulting (amplified) collector-emitter current flow in resistors 11, 13 lowers the bias potential applied to the target electrode 2 and so prevents the video signal output from exceeding such predetermined level. To compensate for temperature responsive changes in the characteristics of transistor 10 the (negative) reference potential applied to clamp 8 may be derived from a resistance chain including a negative temperature coefficient resistor (Fig. 2, not shown). Alternatively, temperature compensation may be effected by including in the video signal path to transistor 10 the base emitter circuit of a further transistor of opposite conductivity type (Fig 3, shown).
