Abstract: A wrapped conduit and method of forming it are described in which a layer of hot applied cold flowable waterproofing material of nonuniform thickness is flowed onto a conduit, and over said layer is spirally wrapped under tension a sheet of a nonwoven permeable randomly arranged heat-resistant thermoplastic fibers. An outer or shielding wrap of asbestos felt, plastic film, kraft paper, or the like, is also employed. The product thus obtained has a waterproof layer of essentially uniform thickness which impregnates the sheet of aforesaid fibers.
Abstract: Apparatus is disclosed for discriminating between desired and undesired fluids such as kerosene. The apparatus is especially adapted for improving the safety of kerosene heaters by discriminating between kerosene suitable for heater use and more volatile materials such as gasoline. Structure is disclosed to terminate flow of fluid to a kerosene heater in response to the sensed presence of a fluid other than kerosene. According to a preferred form of the apparatus, additional structure is provided to prevent fueling a kerosene heater by structure other than that operatively associated with fluid discriminating structure. According to the more specific aspects of the fluid discriminator, a float including magnetic or light-responsive actuators is calibrated to permit or cease the supply responsive to the position of the float in the fluid. A fluid less dense than kerosene, such as gasoline, will cause the float to sink within the fluid and thereby terminate the flow of fluid to the kerosene heater.
Abstract: A plug assembly for use in a thermal-medium passage in a unit curtain wall, for example, comprises a circular gasket seat having a central cylinder with an annular elastomeric gasket placed on the gasket seat around the central cylinder, and a sleeve fitted over the central cylinder and fastened thereto by a fastener such as a hexagonal socket head cap screw threaded through a bottom of the sleeve axially into the central cylinder. When the plug assembly is to be put in the thermal-medium passage, the plug assembly is inserted into the passage with the fastener slightly loosened. After the plug assembly has been pushed to a desired position in the passage, the fastener is tightened by a tightening tool until the annular elastomeric gasket is resiliently squeezed between the sleeve and the gasket seat radially outwardly against an inner circumferential wall of the passage. A heat-transporting medium such as hot water can be prevented by the annular elastomeric gasket from flowing through the passage.
Abstract: A hollow filament wound tube having a plurality of cylindrical, hollow, open ended load bearing shells embedded between radially spaced layers of fiber of the filament wound tube, the shells having a longitudinal dimension less than that of the filament wound tube.
Abstract: A balloon-inflation and load-lowering device which comprises an inverted cup-shaped member containing one or more side-opening ports operative when covered by the neck of a balloon to cooperate therewith and form a one-way valve effective to trap the lifting gas inside the balloon once the latter is inflated and the inflation pressure released. Spaced-parallel disk-supporting arms journal a shaft mounting a notched disk. A load-letdown device is operative to slowly lower a load to the end of a tether.
