摘要： Assembly and method of installing an electrode of a predetermined size and configuration in an electric heater envelope having an electrode opening at a preselected position. The assembly and associated method consist of affixing a hollow compression fitting about or within the electrode opening and providing a sleeve of a refractory deformable dielectric material within the fitting through which the electrode passes into the envelope. Dielectric spacing means are positioned between the electrode and electrically conductive portions of the fitting or envelope to prevent electrical conduction therebetween. Compression fastening means are then provided, securable to the fitting, to impart sufficient compressive force to the assembly to deform the sleeve about the electrode, thereby effectively sealing and securing the electrode within the fitting without the electrode grounding against the fitting or the envelope.

摘要： Ceramic honeycomb structures having channels that are selectively sealed at alternate faces of the honeycomb are prepared by applying an end cap made up of green ceramic material to each face of a green ceramic honeycomb body, followed by exposing the openings of certain channels of the honeycombs through the cap at one face and exposing the remaining channels through the cap at the other face. Thereafter, the composite capped structure is fired. The honeycombs are useful in a variety of filtering, separating, or concentrating operations in which a work fluid or component thereof is intended to pass through the walls of the channels.

摘要： Power is mechanically transmitted from a tethered airship carrying wind turbines to electrical generators on the ground at the anchor point of the tether, by the use of endless power-transmission cables bridging between drive sheaves at the turbine wheels and driven sheaves at the generators. Tether adjustments, cable tensioning, and wind direction changes are provided for the ground apparatus. A tubular aircraft with recess in the tube wall, carrying bearings on which the rims of the turbine wheels ride, is also claimed.

摘要： A turbine wheel on a horizontal axis is coaxially mounted within a primary nozzle, for support in a fluid current below a platform carrying electrical power generation equipment. The turbine wheel and primary nozzle are submerged and oriented to enable flow of a portion of fluid current through the nozzle and past the turbine wheel.The turbine wheel comprises a shroud-ring rim, a set of blades extending inwardly toward the axis, the blades being mounted at their outer ends on the inside of the rim, and at their inner ends on the outside of an axial hub. Each blade has its longitudinal tensile elements shaped in the form of part of a relaxed catenary, extending from rim to hub, with sufficient bow in the direction of force of fluid current on the blade to provide a practical wheel of reasonable cost. Struts and strut vanes supporting hub elements within the nozzle may also be of relaxed catenary configuration.

摘要： An adjustable pitch aircraft propeller has peripherally spaced composite blades each including an elongated core of expanded rigid foam material extending from a metal base member having a reduced neck portion and an outwardly projecting flange portion. A casing or skin of plastic resin impregnated fabric material surrounds the core of each blade and extends inwardly along the neck portion and also has a flange portion overlying the flange portion of the base member. The skin material overlying the neck portion of the base member is retained by a filament winding impregnated with plastic resin, and the blade is coupled to the propeller hub by an annular lip portion which projects inwardly and overlies the flange portion of the skin material. The foam core of each propeller blade has longitudinally extending slots, and strips of resin impregnated fabric material extend through the slots to form corresponding webs which connect the skin material forming opposite side of the propeller blade.

摘要： A power plant for the generation of electricity from the flow of water currents uses turbine wheels within nozzles submerged in the water current, anchored to the bottom of the water course, as for example, the ocean, and self-buoyed to a level well below the water surface. Pairs of counter-rotating turbines are supported by their rims, which bear against friction drive wheels, which in turn drive electrical generators contained in water-tight machine rooms within the wall of the nozzle. A structural design is disclosed, providing for the building of modules of the nozzle ashore, which modules may then be barged to the deep-water site for assembly into the whole power plant.
