Abstract: The invention relates to thienopyridazinones of formula (I): wherein: R1 is C1-6 alkyl, C2-6 alkenyl or C3-6 cycloalkyl which is optionally substituted by C1-6 alkyl, each of the above being optionally substituted by one or more halogen atoms; R2 is C1-6 alkyl; R3 is a group CO-G or SO2-G where G is a 5- or 6-membered ring containing a nitrogen atom and a second heteroatom selected from oxygen and sulphur adjacent to the nitrogen, and optionally substituted by up to 3 groups selected from hydroxyl and C1-4 alkyl; Q is CR5R6 where R5 and R6 are as defined in the specification; and R4 is a 5- to 10-membered mono- or bi-cyclic aromatic ring system, containing 0 to 4 heteroatoms independently selected from nitrogen, oxygen and sulphur, the ring system being optionally substituted as described in the specification, and pharmaceutically acceptable salts and solvates thereof.

Abstract: The invention provides pharmaceutically useful thieno[2,3-d]pyrimidinediones, processes for their production, pharmaceutical compositions containing them and methods of treatment involving their use.

Abstract: A container (10) (or other returnable item) for the storage and delivery of goods, comprises antenna means (16) for radio frequency use, and connection means (18) for receiving a removable drive circuit means (20). The drive circuit (20) is operable to communicate by means of the antenna (16) when connected therewith. The connections (18) serve, in use, to connect an installed drive circuit (20) with the antenna (16) to allow the drive circuit (20) to communicate. This allows the identity of the container or its contents to be communicated to a remote location.

Abstract: The invention provides certain pyrrolo-, thieno-, furano-and pyrazolo-[3,4-d]-pyridazinones, processes for their preparation, pharmaceutical compositions containing them, a process for preparing the pharmaceutical compositions, and methods of treatment involving their use.

Abstract: A user-interface system adapted to navigate through a plurality of menus is disclosed. The system comprises a display system comprising a display having a category area on a first portion of the display, the category area displaying a plurality of categories, including a currently displayed category. Each of the plurality of categories has a plurality of items. The display also has a marquee area on a second portion of the display, which displays items of the currently displayed category. The system further comprises a scrolling mechanism for scrolling through items of each category of the plurality of categories. The marquee area is updated by the scrolling mechanism to display the corresponding items in each category. The scrolling mechanism also indicates a position of a currently displayed item of a currently displayed category by updating the category area. Various embodiments are disclosed.
