Abstract: A multi-phase polymeric gel electrolyte for use in a rechargeable lithium battery has an ion-conductivity of more than 1 mS/cm and comprises a continuous ion-conductive liquid phase interpenetrating a solid phase. The solid phase which is obtained by polymerizing alkane monomers has a microscopic network structure which is selected such that when the electrolyte is employed in a rechargeable lithium metal battery, the battery is capable of being fully charged and discharged at a 0.2 C rate more than 20 times without short-circuiting due to dendritic growth. Suitable microscopic network structures are obtained using polydecandioldiacrylates. A method of preparing said electrolytes involves polymerizing a one-phase polymerizable composition which undergoes 1a phase separation during polymerization.

Abstract: In a plasma-addressed display device according to the invention, a group (G) of three pixels (16) is constituted out of one common data electrode (18) and a group of plasma channels (20). The colour filters are aligned with the plasma channels (20) of the group. In this way the number of data electrodes (18) and thus the number of connections thereto reduces by a factor equal to the number of pixels (16) in a group (G). The number of plasma channels (20) increases with the same factor, but the total number of connections decreases as the number of rows is lower than the number of groups (G) of pixels (16).

Abstract: The fluid delivery/refilling system includes a unit-of-use fluid reservoir for dentifrice or medication within a head portion of a power toothbrush, which is removable from the remainder thereof. A pump element is located in the brushhead and is configured so that the back and forth movement of the brushhead in operation results in fluid moving from the reservoir to a dispensing valve located in the brushhead. The dispensing valve has an end portion which is normally closed, opening under pressure of fluid from the pump. The refilling assembly is separate from the toothbrush and is configured to fit over the top of the toothbrush. Upward pressure exerted on the toothbrush when the toothbrush is within the refilling assembly results in movement of a core element in the refilling assembly, which in turn results in a hollow needle in the refilling assembly extending into a refiller valve in the head portion of the toothbrush.

Abstract: The device for disinfecting water comprises a gas discharge lamp including a discharge vessel with walls composed of a dielectric material, which walls are provided on their outer surfaces with at least a first and a second electrode, and which discharge vessel contains a gas filling containing xenon, the inner surface of the walls being at least partly covered with a coating containing a phosphor emitting in the UV-C range. Such a device for disinfecting water can always be made 100% operation within milliseconds, and the UV-radiation of the device has a spectral composition which lies exclusively in the range relevant for disinfecting, i.e. between 230 and 300 nm.

Abstract: A simple and reliable method of providing a vertical interconnect between thin-film microelectronic devices is provided. In said method, a tool tip is used to make a notch in a vertical interconnect area of two organic electrically conducting areas separated from each other by an organic electrically insulating area. The method is used in the manufacture of integrated circuits consisting substantially of organic materials.
