Abstract: A nappy comprising an outer cover (1) for wrapping around a wearer' s waist and bottom and for holding an inner absorbent layer (2) to the wearer, said outer cover (1) being securable about the wearer by fastening points (10,11) provided on front and rear areas thereof; wherein said outer cover (1) is foldable for adjusting its length such that, in use, the waist height of the nappy is adjusted; and wherein one of the front or rear areas of the outer cover (1) comprises a reversible panel (8), said reversible panel (8) having fastening points (11) provided on both sides thereof and being reversible for exposing fastening points (11) on an exterior surface of the outer cover (1) when said outer cover (1) is folded. In this way the size of the nappy can be adjusted to fit a particular wearer's waist height.

Abstract: Benzodiazepine derivative of formula (I), and pharmaceutically acceptable salts thereof, are found to be active against RSV.

Abstract: An electromagnetic medical applicator for tissue-heating comprises a single resonant element (1) in contact with one surface of a layer of material (5) whose opposite surface faces the body of a patient (6). The material has a wave-impedance which approximately matches that of the human body and a dielectric constant not less than for a material having unity magnetic permeability which produces this match. In one form the element is a patch resonator (1) on a substrate (2) backed by a ground-plane (3) and overlaid by the layer (5); at least the substrate may include both dielectric and magnetic material in order to combine a desired resonator size-reduction and wave-impedance. In another form a needle-type applicator is coated with the layer of material.

Abstract: An antenna array comprises a dielectric image waveguide (3) acting as a feeder, which may be of the insular or inverted-strip type, in contact with a dielectric sheet (1). On the sheet (1) is located a plurality of strips (4) of metallizing extending outwards from the feeder-guide (3). The inner ends of the strips are located to couple with the feeder-guide and their outer ends act to radiate or receive most of the power. Preferably the mode propagated in the feeder-guide is an E.sub.mn.sup.y mode higher than the fundamental, suitably the E.sub.21.sup.y mode.

Abstract: This invention relates to radio antennae, and in particular to dielectric-clad antennae of the kind comprising a length of conductor the electrical length of which is effectively increased by a cladding of dielectric material. The disclosure describes how the physical height of an antenna, typically an HF or VHF wire monopole antenna can be reduced in relation to its electrical length by means of a thin cladding of dielectric material having a relative magnetic permeability substantially greater than unity, e.g. ferrite. By selecting a material having a relative magnetic permeability substantially greater than its relative dielectric permittivity, a given reduction in antenna height can be achieved with a much thinner cladding than can be achieved using conventional materials.
