Abstract: ELECTROMAGNET  DEVICE            ABSTRACT OF THE DISCLOSURE         An electromagnet device comprising a fixed core having two legs defining an opening therebetween, an armature disposed relative to the fixed core such that a zone at one end thereof and a zone at the associated leg portion of the fixed core overlap each other through a gap, and a solenoid coil arranged to encompass these overlapping zones so as to urge the armature toward the fixed core when energized.  The magnetic flux produced by the solenoid coil passes substantially wholely through these overlapping zones of wide contact area thereby in-creasing the attracting force attracting the armature toward the fixed core.

Abstract: ABSTRACT OF THE DISCLOSURE   A method for selectively extracting metal values from manganese bearing ores such as marine nodules.  The ore is initially leached to sol-ubilize manganese and other desirable metals as nitrates.  The resulting solution is then traated with manganous hydroxide to selectlvely precipitate metals such as copper, nickel and cobalt.  The enriched mixture of metal hydroxides is separated from the manganese nitrate solution, which is de-composed to recover high purity MnO2.

Abstract: ABSTRACT OF THE DISCLOSURE A subsea wet electrical connector capable of repeated mating and unmating underwater at great depths and capable of operating under conditions of continuous and simultaneous high amperages and high voltages up to 35,000 volts while mated.  The connector employs cylindrical pin contacts in the male plug and a dummy piston and cylinder mechanisms in the female receptacle to protect the female contact prior to mating.  Dielectric insulating blocks, preferably machined from polycarbonate, and a dielectric insulating fluid provide the electrical insulation for the conductive components of both the male plug and female receptacle.  Passageways within the dielectric block of the female receptacle permit flow of dielectric fluid through the cylinder of the female receptacle during mating and allow convective circulation of the dielectric fluid through the cylinder to dissipate heat from the vicinity of the electrical conductors and solid insulating blocks.

Abstract: ABSTRACT OF THE DISCLOSURE      Fibrous mat type burner can have mat pieced together with butt joints and very thin layer of resinous sealant uniting the pieces at the joint.  Burners with elongated mats are thus readily manufactured, and can be packaged strapped together in pairs face-to-face and enclosed in telescoping carton halves that allow for packaging burners of different lengths.  Simple cushioning strips such as of folded corrugated cardboard can be inserted between burner faces, and cushioning pads over outer edges of burner backs, before they are strapped together.  Holes can be provided in the cushioning strips to hold them in place over fastener heads projecting from burner face.  Burners with hat-shaped mats for enveloping and brazing heat-exchange tubes to tube sheet can be used individually or in pairs to effect such brazing on tube-and-sheet assemblies secured on rotating table and indexed into position under burners. Suction ring around bottom of burner draws off some hot combustion gases generated in burner.  Lowerinz and raising of burner over top of tube-and-sheet assembly, as well as of suction head against bottom of tube-and-sheet assembly is conveniently effected using large-diameter suction piping with loose joints that allow pipe rotation to accomodate such movement.  The tubes can be staked or expand where they penetrate the tube sheet, to reduce the clearance between them.

Abstract: SWITCH AND CABLE ACTUATOR       ABSTRACT OF THE DISCLOSURE    The actuating knob is biased to a center (off) position and can be actuated in opposite directions in each of two planes.  Actuation in one plane serves to actuate either of two switches.  Actuation in the other plane will actuate either of the same two switches but prior to actuating the switch will mechanically actuate a transmission through a Bowden cable.  The cable wire is connected to the free end of each of two levers pivoted on the mounting bracket.  Each lever is engaged by a pin protruding from a disc carried on the end of a cylinder rockably mounted in the switch casing and actuated by the knob.  When the cylinder is moved from its normal mid position, one of the pins lifts the lever (the other lever has to go along) to lift the cable wire.

Abstract: Abstract.          A pilot valve is described for control of a pulse valve for e.g. production of pulses of compressed air. The pilot valve comprises a housing having an inlet and an outlet, a movable valve element disposed inside the housing, and means for switching said valve element between a closed and an open position, said inlet and outlet communicating in the open position. At least a portion of the interior of the housing presents in one plane a circular shape, the outlet being formed as a radial slot from this portion around at least a  part of the periphery. The valve element is designed as a flexible disc which in the closed position is located in said plane to seal the slot with its outer edge at the inner side of the housing. Said means are arranged to switch the valve element to the open position by giving the disc a curved shape so that the outer edge no longer covers the slot.

Abstract: LOW PRESSURE, TREAD WEAR AND SPEED INDICATOR               FOR VEHICLE TIRE     ABSTRACT OF THE DISCLOSURE           A low pressure, tread wear and speed indicator for a tire includes at least one abutment member secured to the exterior surface of one of the sidewalls of the tire adjacent to the tread, which projects laterally outward from the side-wall.  The abutment member is positioned at a distance radially inwardly from the tread such that, upon tire deflation or excessive tread wear or a combination thereof, the abutment will strike the road surface during vehicle operation, to produce a vibrational and/or audible signal perceivable by the driver, indicating an unsafe tire condition.  The indicator may also include a weighted insert embedded within the abutment member which, upon operation of the vehicle at an excessive or illegal rate of speed, will produce an eccentric tire condition which, in turn, causes a vibrational signal.  A tire deflation indicator which includes a segmented radially-extending rib formed on the interior surface of the tire sidewall is also provided.
