Abstract: GAS TURBINE ENGINE NOZZLE APPARATUS  INCLUDING A NOZZLE FLAP SLOT SEAL             ABSTRACT             Apparatus for modulating the area of a gas turbine engine nozzle which provides for positive sealing between overlapping articulated flaps when the overlapped flap is axially slotted to receive a portion of the overlapping flap.  An arcuate seal is attached to the overlapping flap by means of a floating connection, the overlapping flap dragging the seal therewith in the axial direction.  A seat is mounted on either side of the slot to slidingly receive a pair of shoulders laterally extending from the seal.  A portion of the seal is received within the slot and is so contoured as to partially define the nozzle flow path.  A sleeve captures and supports the seal shoulders during their axial travel.

Abstract: ABSTRACT OF THE DISCLOSURE             An axially compact and highly arc protective base-socket system for use with a color television picture tube having a narrow neck terminated by a cylindrical coaxial tubulation. The tubulation is surrounded by a number of axially extending electrically conductive low-voltage pins and at least one high voltage pin.  The base-socket system comprises a base and a socket.  The base fits over and is secured to the tubulation and passes the pins extending from the neck of the tube.  The base comprises: a plurality of axially and radially outwardly extending insulating walls, the low voltage pins lying between the walls; means defining an axially extending deep narrow cavity which receives the high voltage pin, the cavity having a depth at least twice as great as the largest transverse dimension thereof; and a cavity lip surrounding the mouth of the cavity.  The socket comprises: an annular support means defining a series of axially and radially inwardly extending channels for mating with the insulating walls on the base to unambiguously orient the base relative to the socket; a series of contacts on the annular support means for establishing electrical connection with the plurality of low-voltage pins on the base when the base is inserted into the socket; an axially extending socket protrusion for mating with the axially extending deep narrow cavity; a high voltage contact in the socket protrusion for establishing electrical connection with the high voltage pin on the base when the base is inserted into the socket; a cap having an annular arc-path-length-extending flange which externally telescopes over the cavity lip.          When the base and socket are connected the mating of the socket protrusion and flange with the base cavity and lip form multiply folded extended arc path lengths providing a very high degree of arc prevention in an axially compact system.

Abstract: ABSTRACT A hood for capturing fumes and dust generated during operating of a metal metaling furnace including an integral conveyor for charging the furnace. The furnace has an upwardly opening mouth covered a lid. The hood overlies the lid to capture fumes and dust emanating from the furnace during melting, slagging, pouring, and associated furnace operations. An opening is provided in the hood for insertion of material, e.g., scrap metal, into the furnace. The instant invention includes a conveyor flexibly, e.g., pivotally, mounted between the hood and the lid. The hood opening includes a hopper mounted above the conveyor and opening through the hood into the conveyor. The illus-trated system further includes an opening through the fur-engaging a distal end of the conveyor when the conveyor is moved into a use position. A door is provided to close moving material into the furnace. Another door, which is gravity urged into a closed position, is opened by the convey-or as the conveyor moves from its storage position to its use position. Return movement by the conveyor to its stor-age position allows this last-mentioned door to close.

Abstract: OPTIONAL DISCHARGE OVEN VENT     Abstract of the Disclosure A venting system for a food processing oven includes a duct assembly comprising a housing defining an inlet into which heated air from the oven enters and first and second outlets through which the heated air is expelled to the interior or exterior, respectively, of the household in which the oven is installed.  A serpentine channel formed by a series of parallel plates mounted in the housing between the inlet and outlets is provided to carry the heated air over a relatively long path to cool, permitting water vapor therein to condense on the plates before the air is expelled.  A damper plate is mounted in the housing for pivotal movement in the path between the inlet and second outlet.  A manual selector movable to first and second positions is coupled to the damper plate for movement thereof to blocking and unblocking positions, respectively, with respect to the second outlet.  Movement of the selector to the first position permits the air to pass to the interior of the household via the first outlet, and movement to the second position permits the air to be discharged via the second outlet to the household exterior.  The damper plate is biased normally to the unblocking position.  An actuator mechanism coupled between the manual selector and damper plate, controls the position of the latter in response to the operation of the manual selector.

Abstract: ABSTRACT OF THE DISCLOSURE         A window structure subassembly adapted for easy place-ment in and removal from a conventional window frame.  The sub-assembly includes a generally planar, rectangular window pane constructed of glass, acrylic resin, or the like.  Also included are four frame members, each having a slot extending longitudi-nally therein and receiving the edge of the window pane.  Each frame member further includes an opening for receiving a pin.          Two of the frame members are dimensioned for placement on the top and bottom edge of the window pane and the other two frame members are dimensioned for placement on either side edge of the window pane.  An elongate, wire element formed with a plur-ality of bends is placed in the slot of each frame member to bias the frame member away from the edge of the window pane and against the walls of the window frame to securely hold the window structure subassembly therein.  The window pane includes four apertures each located near a different edge of the pane about midway along the lengths thereof.  A pivot pin is inserted through the opening in one frame member and through a correspond-ing one of said openings in the window pane to thereby serve as a pivot for the frame members.  Such pivoting enables varying the perimeter dimensions of the window structure subassembly to accommodate variations in window frame shapes into which the window structure subassembly might be placed.

Abstract: ABSTRACT OF THE DISCLOSURE :        Disclosed is a method for manufacturing an object of silicon nitride.  In the method, a body preformed from silicon nitride is surrounded with a casing which is permeable to gas. Upon heating, the casing is transformed into a layer which is impermeable to a pressure medium which is used during isostatic pressing of the preformed body while a pressure outside the casing is maintained which is at least as high as the pressure of the gas which is present in the pores of the preformed product.      After the casing has been made impermeable to the pressure me-dium and the preformed body has been enclosed therein, the isos-tatic pressing is carried out while the body is simultaneously sintered.

Abstract: ABSTRACT OF THE DISCLOSURE           A method and apparatus are described for detecting faulty insulators used on overhead power transmission lines.          The apparatus comprises two contact probes, a capacitance, a blocking resistance and a direct current meter in series between the probes to form an open electrical circuit.  Means are provided to prevent discharging of the capacitance while the capacitance is being charged.  In the use of the apparatus, the capacitance is charged from a source of high voltage direct current, the discharging of the capacitance to the source is avoided, the contact probes are sequentially applied across insulators and any current flowing across the insulators is recorded by the direct current meter.  The sequential applica-tion of the contact probes is carried out while the insulators remain in service and the transmission line remains fully energized.  The value of the capacitance is such that a large number of insulators can be tested before recharging becomes necessary.  The value of the resistance is such that a blocking effect exists which causes a current of only a few micro amperes to pass through the current meter when testing a faulty insulator and thus avoids a rapid discharging of the capaci-tance.
