20130344583 | BIOSENSOR COMPRISING AN OXIDASE ENZYME AND A HYDROGEN PEROXIDE INDICATOR MEANS - A biosensor for detecting the concentration of an analyte in wound fluid, the biosensor being at least substantially free of catalase and comprising a sensing means comprising an oxidase enzyme and a hydrogen peroxide indicator means, the arrangement being such that, when a sample of wound fluid comprising the analyte is brought into contact with the sensing means, the oxidase enzyme reacts with the analyte to produce hydrogen peroxide which triggers the indicator means to indicate the presence of the analyte in the wound fluid. | 12-26-2013 |
20150025479 | SKIN DRESSING WITH ELECTRODES AND PHYSIOLOGICALLY ACTIVE PRECURSOR SUBSTANCE - A skin dressing comprising first and second electrodes, an electrical power supply not electrically connected to either or both of the first and second electrodes, and further comprising a physiologically or antimicrobially active precursor substance, the dressing being operable, when placed on a skin site to be treated, to connect the electrical power supply to both the first and second electrodes, thereby to trigger the electrochemical oxidation or reduction of the precursor substance on one of the electrodes to produce a physiologically or antimicrobially active oxidised or reduced compound which is capable of diffusing towards the skin site for the treatment thereof. | 01-22-2015 |

20140343340 | DEHYDROXYLATION OF POLYETHER POLYOLS AND THEIR DERIVATIVES USING A HALOGEN-BASED CATALYST - Polyether polyols, derivatives and combinations thereof are converted to olefins under reductive or non-reductive dehydroxylation conditions, in the presence of a halogen-based catalyst. Derivatives include polyether polyols incorporated in polyurethanes. The process includes gas pressure from 1 psig (˜6.89 KPa) to 2000 psig (˜13.79 MPa), a temperature from 50° C. to 250° C., a liquid reaction medium, and a molar ratio of the starting material to halogen atoms from 1:10 to 100:1. | 11-20-2014 |
20140357920 | IODINE-BASED CATALYST FOR REDUCTIVE DEHYDROXYLATION OF VICINAL POLYOLS TO OLEFINS - Olefins are produced by the reductive dehydroxylation of vicinal polyols or esters thereof, or a combination thereof, in a liquid reaction medium, under a hydrogen atmosphere, at a temperature from 50° C. to 250° C., in the presence of a halogen-based, preferably iodine-based, catalyst. Examples of the catalyst, which may be included independently or generated in situ, are iodine (I | 12-04-2014 |
20140357921 | DEHYDROXYLATION OF CRUDE ALCOHOL STREAMS USING A HALOGEN-BASED CATALYST - Crude alcohol streams are converted to olefins under reductive or non-reductive dehydroxylation conditions, in the presence of a halogen-based catalyst. The process includes autogenous gas pressure or a gas pressure from 1 psig (˜6.89 KPa) to 2000 psig (˜13.79 MPa), a temperature from 50° C. to 250° C., a liquid reaction medium, and a molar ratio of alcohol to halogen from 1:10 to 100:1. | 12-04-2014 |
20140378729 | REDUCTIVE DEHYDROXYLATION OF VICINAL POLYOLS TO OLEFINS USING AN IODINE-BASED CATALYST HAVING ENHANCED SOLUBILITY - Olefins may be produced by the reductive dehydroxylation of vicinal polyols and/or their respective esters, in an aqueous reaction medium, under a hydrogen atmosphere, under suitable conditions, and in the presence of a halogen-based, preferably iodine-based, catalyst, wherein a solubility enhancing agent is employed to increase the solubility of the iodine-based catalyst in the aqueous reaction medium. | 12-25-2014 |
20140378730 | NON-REDUCTIVE DEHYDROXYLATION OF VICINAL COMPOUNDS TO OLEFINS USING A HALOGEN-BASED CATALYST - Olefms may be produced by the non-reductive dehydroxylation of vicinal polyols and/or their respective esters, in a liquid reaction medium, under a substantially non- reductive atmosphere, in the presence of a halogen-based, preferably iodine-based, catalyst. The reaction medium may be aqueous, non- aqueous, or a combination thereof, and may in some embodiments include a solubility enhancing agent. | 12-25-2014 |
