Abstract: Described herein are micronized powder particles of colistimethate sodium wherein at least 50% by volume of the micronized particles have a diameter of less than 7 micrometers but not less than 3 micrometers and the powder has a total moisture content of from 5 to 10% by weight, for use in the treatment of a pulmonary infection by powder inhalation, wherein the colistimethate sodium is not separated into component form. The micronized powder particles of colistimethate sodium are useful in the treatment of infections caused by gram-negative bacteria, particularly in patients suffering from cystic fibrosis.

Abstract: A dental care device for selective use as a toothbrush or a dental floss source. The device comprises an elongate body, wherein the body defines cavity used as a dental floss reservoir, a brush element proximal to a first end of the body, a floss egress aperture at a second end of the body. The brush element including a plurality laterally extending bristle members. The body includes a window element for enabling visual inspection of a dental floss remaining in the reservoir. A dental floss source includes a spool of dental floss mounted within the reservoir such that dental floss can be drawn from the spool.

Abstract: A damper (18) for a rail (10), includes a deformable material (20) and an elongate resonant member (20, 24), the resonant member being of a stiff material as compared to the deformable material and being sized to exhibit a resonant frequency in the range of vibration frequencies of the rail, wherein the resonant member includes a clip (26) extending therefrom so as to retain the resonant member and the deformable material in place on the rail. The clip preferably extends laterally of the resonant member to grip the underside of the rail. The clip can have an engagement formation on the end thereof, to engage with a like formation of a further damper located on the opposing side of the rail.

Abstract: A rail damper including an elongate damping device and a clip for supporting the damping device, the clip having a retention aperture for receiving part of the rail and, further, a recess adapted to receive the damper. This is particularly (although not exclusively) suited to dampers in which an elongate hollow rigid section encloses a deformable material in which is suspended one or more resonant members. The clip can be adapted to fit around the foot of the rail. It can include one or more tongues extending alongside the web of the rail. This will assist in separating the damper from the web while still allowing vibrations to be conducted from one to the other. The tongues can be any suitable height, for example the full height of the web, or the full height of the dampers, or less than one or other such heights.

Abstract: An air monitoring system includes a tubing having a metallic inner layer and an outer jacket to provide optimal transport of air samples.

Abstract: A damper for reducing the track nose emitted by a rail system comprises a deformable material attachable to a surface of the rail, incorporating a plurality of elongate discontinuous resonant members of a stiff material as compared to the deformable material, sized to contain at least two resonant frequencies in the range of interest. The resonant members are suitably of steel or other metallic material. They can be of different profile, to form a resonant system with at least two resonant frequencies in the relevant frequency range. They are suitably embedded in the deformable material, to ensure adequate vibrational transfer from the rail to the resonant members and also provide environmental protection. The deformable member is visco-elastic, for example rubber or rubber-like material. This may be preformed and glued to the rail, or it can be cured in place on the rail. The damper is positioned on the rail at the junction between the web and the foot of the rail.
