    Abstract: Adhering to an electric water heater is a porous layer of heatfused insulating material powder covered by an adhering porous layer of heat-fused electric resistance powder having a negative temperature coefficient of resistivity. The pores of the two layers are filled with dielectric material. Electric terminals connected to the resistance layer are electrically connected with current-actuated circuit breaking means that will be operated by increased current flow through the resistance layer if that layer reaches a predetermined maximum temperature, whereby the water heater is fail safe.

    Abstract: Radar and other electronic devices which rely for information upon reflection of a primary wave-form signal are jammed by interposing in the path of the primary signal chaff of compacted vermiform, or expanded, graphite. The primary signal may be electromagnetic, as in the case of radar, or it may be sonic, as in the case of sonar.

    Abstract: Ferrite powder is flame sprayed onto a glass or ceramic substrate to form a continuous coating, in which the powder is fused together and to the substrate to form a radiation shield. When the substrate is the glass envelope of a television receiver high voltage rectifier tube, such a shield in the correct location will absorb most of the X-rays that otherwise would be emitted by the tube.

    Abstract: The front wall of the oblong case of a linear motion potentiometer is provided with a longitudinal slot, in which a slide is disposed. The slide carries a bridging contact inside the case, where it engages spaced parallel resistor and collector elements. In front of the case and parallel to the slot is a lead screw rotatably supported from the case. Rigidly mounted on one end of the screw is a member for rotating it. An arm that is rigidly joined to the slide extends outwardly across the screw and is provided with a portion registering with the screw thread. When the screw is turned, it will move the arm and slide lengthwise of the case.

    Abstract: An elongated porous member is impregnated with a combustible fluid and then floated in a generally upright position in a layer of combustible fluid on a body of water, with the lower portion of the porous member extending down in the water and with its upper portion projecting above the fluid layer. The fluid carried by the upper end of the porous member is ignited to produce a flame that is thereafter fed by combustible fluid moving up through that member by capillary action from the fluid layer, whereby to remove the fluid from the water and burn it.

    Abstract: A slide is movable lengthwise of a housing to move contact means therein along conducting means. Secured to the housing is a stationary rack bar that is longer than the housing and supports a carrier movable along the bar. A rack bar, which is movable lengthwise along the stationary bar and carrier, is connected with the slide for moving it. Rotatably mounted on the carrier is a pair of rigidly connected coaxial gears, one of which is smaller than the other. The large gear meshes with the stationary rack bar and the smaller gear meshes with the movable rack bar. When the gears are rotated, the one engaging the stationary bar will move the carrier along the bar, and the other gear will move the movable bar along the stationary bar a shorter distance than the carrier moves so that the slide will be moved only the shorter distance.

    Abstract: In accordance with this invention barium ferrite hard magnetic materials are produced by quenching a molten homogeneous composition of B2O3, BaO and Fe2O3 within the area ABCD of FIG. 1 to form a homogeneous, substantially noncrystalline glass, heating the quenched glass to nucleate and crystallize barium ferrite in a borate-rich matrix, and separating the matrix material from the crystallized barium ferrite.

    Abstract: A plurality of wires are fed radially inward toward a common central point and then are stopped a predetermined distance from it. Then a rigid ring of insulating material, concentric with the same point, is molded around the wires near their inner ends, after which the wires are severed a short distance from the outside of the ring. The short lengths of wire left embedded in the ring project from the inside to form electric contact pins, and project from the outside to form electric terminals. The severing of the long wires may be done by lifting the mold, in which the wires are embedded in the insulating ring, to cut the wires where they emerge from wire-guiding means around the mold.
