Abstract: An insulated mounting support is provided for installation near a feedpoint f a ladder-line transmission line. A first plate of electrical insulator material has a face from which two bosses extend, and has opposing sides abutting the face from which first and second appendages extend. A second plate of electrical insulator material has two recesses in a face thereof for mating engagement with the two bosses. The two bosses are maintained in a spaced apart relationship in correspondence with two cutouts provided in the transmission line. When the first plate and second plate are sandwiched about the transmission line near the feedpoint, the two bosses extend through the two cutouts and engage the two recesses. In this way, tension in the transmission line is absorbed by the two bosses. In addition, the first and second appendages respectively coact with first and second conducting wires extending from the transmission line at the feedpoint.

Abstract: An apparatus for assembling a tube and a part has a polymeric tube with an axis along the longitude thereof. The part has a cross sectional shape and size to be near an inside surface of the tube when the part is at least partially therewithin. The part or tube is supported so that relative movement along the axis places the part at least partially within the tube located between the ends or in the tube near the distal or proximal end thereof. The part and/or the tube is a thermoplastic polymer made by a process that develops within the polymer a memory of the polymer prior to forming so that residual stresses remaining in the part can be relaxed by changing temperature causing expansion. A form of a relatively nonconductive material is positioned for relative movement along the axis and for placement about the tube. The form is shaped and sized to fit and contain the outside surface of the tube.
Abstract: An electronic device package includes a portion that functions as a membrane to allow small molecules, such as gas molecules, to relatively freely traverse the housing boundary, while simultaneously substantially preventing large molecules, such as liquid molecules, from entering the confines of the housing.
