Abstract: An inhaler with an inner housing with a pressurised reservoir of an inhalable composition. A breath operated valve is operable by a user inhaling on an inhaling end of the inhaler. A composition flow path extends from the breath operated valve to the inhaling end via which the composition is dispensed when the breath operated valve is opened. The breath operated valve is biased closed by a biasing member contacting the breath operated valve at one end. A bung in the inner housing is positioned in an opening in the inner housing to support the end of the biasing member opposite to the breath operated valve. A rigid outer housing surrounds the inner housing and supports the bung.

Abstract: Headphone apparatus including earpieces and a module including an audio signal source. The earpieces are each tethered to the module by elongate elastic connectors that each include a wire for carrying the electrical audio signals from the module to the earpiece. Each elongate elastic connector has a preformed geometry such that a first part of each elongate elastic connector provides an ear hook that, when worn, lies directly over the otobasion superius of the wearer, and a second part of each elongate elastic connector provides a tension spring that provides a tension on the ear hook when the apparatus is worn.

Abstract: An inhaler comprising an inner housing (1) with a pressurised reservoir of an inhalable composition. A breath operated valve (5) is operable by a user inhaling on an inhaling end of the inhaler. A composition flow path extends from the breath operated valve (5) to the inhaling end via which the composition is dispensed when the breath operated valve is opened. The breath operated valve (5) is biased closed by a biasing member contacting the breath operated valve at one end. A bung (16) in the inner housing is positioned in an opening in the inner housing to support the end of the biasing member (8) opposite to the breath operated valve. A rigid outer housing (3) surrounds the inner housing and supports the bung (16).

Abstract: Scales include at least one transducer, a weighing pan arranged such that weight applied to the weighing pan is referred to the transducer, and electronics which receive an output from the transducer and drive a display to provide a user with a visible indication of the weight applied to the weighing pan. The transducer and electronics are contained in a sealed enclosure defined at least in part by a flexible water-tight membrane which is able to move and thereby (a) to accommodate changes of volume of the sealed enclosure without creating a pressure differential between the interior and the exterior of the sealed enclosure and (b) to accommodate movement of the weighing pan. The water-tight membrane may include a double film comprising a saturated salt solution between two films.
