Abstract: A disposable set of components for an organ perfusion system comprising a fluid supply duct for supplying fluid to the organ, a fluid removal duct for removing fluid from the organ, and a surrogate organ removably connected between the fluid supply duct and the fluid removal duct so as to form a fluid circuit, so that fluid can be circulated in the circuit in preparation for connection of the organ.

Abstract: A device, including a behind-the-ear (BTE) device ear interface fixture, the fixture including a loop portion configured to enable a pinna of a recipient to be inserted there through and an attachment portion configured to removably attach the fixture to a BTE electronics module and/or a BTE battery, wherein the inner perimeter of the loop portion is non-circular when the loop portion is in a relaxed state.

Abstract: An ear hook apparatus, including an ear hook tip, an ear hook chassis, and a male connector, wherein the ear hook apparatus is configured such that the male connector attaches to one or more components of a BTE device at and/or below a base of a BTE electronics module of the BTE device.

Abstract: The present invention provides a process for producing diphthaloyl peroxide comprising the steps of reacting particulate phthalic anhydride with aqueous hydrogen peroxide in a mobile slurry or paste and thereafter separating diphthaloyl peroxide from the aqueous phase. Preferably the minimum volume of hydrogen peroxide solution is employed commensurate with obtaining a mobile slurry or paste in a mole ratio of phthalic anhydride to hydrogen peroxide of 4:3 to 1:3. Preferably the reaction is effected at a temperature of from 25.degree. to 50.degree. C.Diphthaloyl peroxide is particularly suitable for washing/bleaching fabrics, optionally in conjection with an inorganic persalt e.g. sodium perborate, at a temperature of from 30.degree. to 60.degree. C.

Abstract: The present invention provides a process for making diphthaloyl peroxide by reacting phthalic anhydride with aqueous hydrogen peroxide at a pH controlled to between pH 8 and 10, preferably pH 8.8 to 9.2 and a low temperature preferably maintained at 0.degree. to 5.degree. C, and thereafter removing diphthaloyl peroxide from solution, suitably by acidification and filtration. Preferably excess solid phthalic anhydride is employed and is filtered out before the solution is acidified. Desirably the concentration of active oxygen species is maintained at below 0.3 moles/liter.Diphthaloyl peroxide is particularly suitable for bleaching/washing fabrics, optionally in conjunction with an inorganic persalt e.g. sodium perborate, at a temperature of from 30.degree. to 60.degree.
