Abstract: A conduit and cable sealer comprising a resilient cylindrical base terminating in opposed end faces with a circumferential flange extending transversely from one of the faces. A plurality of boreholes extend through the base between the two faces. Cable-accepting seals having stepped towers are insertable in and removable from the boreholes and provide a frictional fit with the internal walls of the boreholes. The base with cable-accepting seals inserted frictionally fits within an end of a conduit so as to seal that end of the conduit when not in use. When cables are used, the towers are cut to the proper size so as to frictionally fit about the cables.

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 electrical outlet box is molded of plastic and includes push-in type screw receiving openings each of which is defined by rigid first and second walls having opposed semi-cylindrical faces mounted in spaced and axially aligned relationship to produce a generally cylindrical passage open at an outer end. Threads are formed about the interior of the cylindrical passage. In a first embodiment, the first wall is supported and carried substantially entirely by a resilient support wall lying in a plane generally perpendicular to the axis of the cylindrical passage. The support wall is mounted in cantilever fashion at a location spaced radially from the axis of the cylindrical passage so that the first wall can resiliently deflect away from the second wall when a screw is pushed axially into the passageway. In a second embodiment, both the first and second walls are mounted by resilient support walls to allow deflection in the manner described.
