Abstract: Syringes which are suitable for dispensing and injecting medical foams for sclerotherapy are described and claimed. The syringes of the invention comprise a syringe barrel having a nozzle and a bore to receive a syringe plunger; a syringe plunger defined by a front end and a rear end connected by a tubular walls and having an internal hollow duct between the front end and the rear end, and through which foam can flow; and an injectate chamber formed by insertion of the front end of the plunger into the barrel. The syringes comprise a flow-disruptor arranged to modify the flow of foam as it enters the injectate chamber. In certain embodiments the syringes comprise waste chambers which capture and retain poor quality foam. The syringes are particularly useful for dispensing foams made with little or no nitrogen content and are configured to reduce the risk of air contamination during dispensing the foam.

Abstract: A sealed attic insulating and roof ventilating system includes a plenum formed in part by a barrier material attached to adjacent pairs of rafters and having a radiant or reflective upper surface and a corrugated lower surface to which an insulation material may be secured. This arrangement creates an uninterrupted air chamber or ventilation plenum between the barrier material, the adjacent rafters, and the roof decking through which exterior air can circulate unimpeded from the lower vents to the upper vents of the roof. The circulation through the ventilation plenum prevents moisture from accumulating or condensing under the roof decking and warping the roof decking, which ultimately leads to deterioration of the roof decking and failure of the roof covering, and eliminates ice damming on the top surface of the roof covering.

Abstract: A barrier material has an upper, radiant barrier layer and a lower, corrugated surface layer. The radiant barrier layer is preferably a metalized film or an aluminum sheet with an emissivity rating 0.1 or less. The metalized film is laminated to one side of a middle layer using a high, heat-resistant adhesive. The corrugated surface layer, which can receive an insulating material, is preferably a corrugated medium. The corrugated medium is laminated to the other side of the middle layer with a water-resistant adhesive. The middle layer is preferably a fire-resistant, kraft linerboard. The barrier creates an air space or plenum between an external structure and the insulating material designed to prevent heat transfer between an insulated space and the external structure.

Abstract: A closure for a container, and a container incorporating the same, that minimizes or eliminates leakage between the closure and the container holding the liquid. The closure provides a liquid sealing system that allows irregularly shaped closure tops to be used without sacrificing the effectiveness of the liquid seal. In one embodiment, the closure includes a plurality of struts disposed within an annular space that receives a neck portion of the container to create a seating plane that corresponds to a plane formed by the rim of the neck portion.

Abstract: A system for estimating an antenna boresight direction. The novel system includes a first circuit for receiving a Doppler measurement and a line-of-sight direction measurement corresponding with the Doppler measurement, and a processor adapted to search for an estimated boresight direction that minimizes a Doppler error between the Doppler measurement and a calculated Doppler calculated from the estimated boresight direction and the line-of-sight direction measurement. The line-of-sight direction measurement is measured relative to the true antenna boresight, and the calculated Doppler is the Doppler calculated for a direction found by applying the line-of-sight direction measurement to the estimated boresight direction. In a preferred embodiment, the first circuit receives a Doppler measurement and a line-of-sight direction measurement from each of a plurality of pixels, and the processor searches for an estimated boresight direction that minimizes a sum of squares of Doppler errors for each of the pixels.

Abstract: A method and bistatic synthetic aperture radar (SAR) imaging system generate an image of a target area without knowledge of the position or velocity of the illuminator. The system includes an illuminator to illuminate a target area with a null-monopulse radiation pattern interleaved with a sum radiation pattern. The illuminator adjusts the phase terms of the sum radiation pattern to maintain a static electromagnetic field pattern at the target area. A receiver receives the radiation patterns reflected from the target area and generates phase compensation terms by correlating a measured electromagnetic vector field with the known static electromagnetic vector field. The phase compensation terms are used to generate an image of the target area.
