Abstract: A barrier structure comprises: a first membrane substantially reflective of electromagnetic radiation; a second membrane spaced apart from the first membrane and bound to the first membrane about an edge thereof to form a bladder, the second membrane resistant to vapor transmission; and a fibrous insert disposed between the first membrane and the second membrane so as to maintain the spaced apart relationship, the fibrous insert defining a space holding an insulating medium resistant to the transmission of thermal energy and interspersed therethough. The first membrane may further comprise a multilayer composite and may include a polymer resistant to vapor transmission, for example including at least one of H2O, CO2 and O2. The polymer may be a polyester. The multilayer composite may further comprise a structure substantially reflective of thermal energy. The composite may further comprise one or both of an outer metallization layer and an inner metallization layer.

Abstract: This invention relates to telecommunication bandwidth provisioning systems in radio telecommunications. Radio-link networks are inevitably constrained by limited availability of radio channels within the radio spectrum assigned to such use. The consequent need of and benefit from optimising management of assignment of radio channels is self-evident. Such need and benefit are emphasised where different usages by the same subscribers have different radio bandwidth requirements. For example, voice calls generally require less radio bandwidth than data transfers via computer modems, and are typically handled by 32 Kilobits per second (Kb/s) and 64 Kb/s radio channels, respectively. The present invention provides a system and method of operating at different bandwidths and of providing a billing system therefor.

Abstract: A base station antenna arrangement comprising a plurality of antenna arrays each capable of forming a multiplicity of separate overlapping narrow beams in azimuth, the arrays being positioned such that the totality of beams formed by the arrays provides a substantially omni-directional coverage in azimuth, azimuth and elevation beamforming means for each array, a plurality of r.f. transceivers each for transmitting and receiving r.f. signals for one or more calls, switching matrix means for connecting each transceiver with one or other of the arrays via the beamforming means, control means for controlling the switching matrix means whereby a particular transceiver is connected to a particular array via the beamforming means to exchange r.f. signals with a remote station located in the area covered by one of the narrow beams.

Abstract: An improved applicator for soft materials includes a cartridge section and a relatively rotatable body section, the soft material being contained within the cartridge section and a plunger being provided to advance the soft material. The improvement resides in providing an assembly within the applicator body to prevent the inadvertent separation of the cartridge section from the body section. In a preferred embodiment, this assembly comprises a clutch means between the rotatable body section and the plunger whereby rotation of the body is transmitted to the plunger to advance and retract the plunger and associated soft material, the clutch means being designed so as to disengage before the plunger is retracted to the point at which it would forcibly separate the cartridge from the body.
