Abstract: PATENT APPLICATION of BILLY G. CRUTE for PRESSURE-VACUUM RELIEF FUEL TANK CAP  WITH ROLL-OVER SAFETY VALVE FEATURE   (Case 19533.1) ABSTRACT OF THE DISCLOSURE            A pressure-vacuum cap for a chamber such as an auto-mobile gas tank having a normally upwardly extending filler neck formed with a peripherally and radially extending, upwardly facing sealing surface concentric with the longitudinal axis of the neck, the cap comprising a cover, a concentric housing extending downwardly from the cover into the filler neck and a gasket or gaskets providing a seal between the housing and the sealing surface, the housing providing a valve body having a centrally disposed, concentric passageway extending axially therethrough and in communication with the chamber.  A pressure-vacuum valve assembly is disposed in that passageway for norma-lizing the pressure in the chamber, venting the chamber to atmosphere when the pressure in the chamber exceeds a predetermined superatmospheric level and when the pressure in the chamber drops below a predetermined subatmospheric level.  The cap also pro-vides, in addition to the pressure vacuum valve assembly, a roll-over valve assembly.  Particularly, a rubber-like insert is disposed in the passageway to provide a downwardly facing, generally conical valve seat, and a ball is disposed in the passageway to move against the valve seat to close the passage-way against movement of fluid from the chamber when the filler neck is tilted downwardly to a predetermined angle relative to a horizontal plane.  The rubber-like insert also provides a seal against the pressure-vacuum valve assembly.

Granted: 1982-05-25
Abstract: Abstract of the Disclosure Electromagnetic relay having a coil-wound bobbin with flanges at each end, a reed mounted on one flange and extend-ing through the bobbin, fixed contacts mounted on the other flange cooperating with a free end of the reed, and a casing formed by a base and a cover.  An upwardly projecting peripheral wall is provided on the base, and the lower edge of the cover engages the peripheral wall.  Coil, reed and contact terminals extend through bores formed in the casing base.  Grooves in the lower side of the base communicate with the bores and with the lower ends of passages which emerge at the peripheral wall.  Sealant filled in the grooves simultaneously seals the terminals in the bores and the cover to the base.  When the cover engages the interior of the peripheral wall, webs provided on the upper side of the casing base confine the sealant to the bores and to pockets provided at the outer side of the cover.  The bobbin flange interior has a separator against which the fixed contacts abut to define the spacing between the fixed contacts.  The separator also defines the spacing between the free end of the reed and a permanent magnet which cooperates with pole shoes connected to the fixed contacts.

Abstract: Abstract of the Disclosure A molten metal feed tip for a continuous caster for aluminum or the, like is made by forming a slurry of refractory fibers in an aqueous solution containing a dispersion of colloidal silica. Liquid is extracted from the slurry to form a flexible felt blanket of refractory fibers which is then compressed in a closed die cavity having the desired geometry of one moiety of the molten metal feed tip.  The felt blanket is heated in the closed die cavity to a sufficient temperature to extract water from solution remaining in the blanket to form one rigid moiety of the feed tip.  Two such moieties are assembled to form a feed tip having a molten metal feed gap therebetween.   The feed tip tapers towards the downstream edges which are compressed to a higher density than the upstream portion of the feed tip.  The downstream edges have a greater thermal conductivity than the thermal conductivity of the upstream portion.  The inside surfaces of the feed tip can be coated with glass fabric and the outside coated with metal foil to resist moisture.  The inside and outside faces have generally planar portions converging from the upstream portion toward the downstream edges.

Abstract: ABSTRACT OF THE DISCLOSURE         A discharge flow regulating device for regulating the discharge of sponge metal from the bottom of a vertical, moving bed reduction reactor.  A frusto-conical baffle near the bottom of the reactor directs the flow of particles toward a horizontal plate spaced from the baffle and having a diameter sufficient to block the passage of the particles.          Gas under pressure is supplied to the center of the plate and directed radially outward to blow particles over the rim of the plate. The supply of pressurized gas is regulat-ed to regulate the rate at which particles are forced to and over the perimeter of the plate.  The gas also serves to cool the sponge metal in the lower portion of the reactor.

Abstract: ABSTRACT OF THE DISCLOSURE         A machine for cleaning e.g. the reactor cavity walls in a nuclear power plant by means of at least one rotatable roller brush.  For cleaning machines suspended by a wire it is difficult to achieve a sufficient bearing pressure against the wall to be cleaned.

Abstract: ABSTRACT OF THE DISCLOSURE         High strength, low alloy steel is produced, preferably as a hot rolled article (e.g. strip), to have a rimmed skin of essentially ferrite while having a main body or core which is aluminum-killed and comprises, for superior mechanical properties including yield strength, a suitable quantity of columbium and/or vanadium,  The carbon, manganese and sulfur contents of the base metal, which provides the skin and plus the addition, the core, are preferably limited to provide special results as low alloy steel and also, by the same limitations, to provide auto sulfide shape control and thus to avoid unwanted directionality regarding toughness and bendability. The steel is made by pouring a mold 80-95% full of the base composition, then allowing the steel to rim for several minutes, and after a shell has solidified, continuing to pour while adding Al and Cb or V to the teemed stream, thereby providing an ingot with the above killed core, which can be hot reduced as desired.

Abstract: Abstract of the Disclosure Disclosed is a new fastening system particularly for fastening of fiber reinforced polyester/plywood panels to metallic structural members in sealing engagement through apertures.  The system has a sealing capped nut for receiving in threaded engagement a bolt.          Upon such engagement a formable shank portion of the sealing capped nut is deformed in a designed fashion to form a seal between the bolt  and the aperture opening.          The sealing capped nut and shank portion includes a tubular end formed of a deformable material, the shank having a length greater than those of the apertures in the article.  An accompanying bolt insertable into the capped nut and has a hem forming surface so that when the members are assembled the surface readily deforms the tubular end and produces a radially extending, periphery continuous hem which engages around the aperture and is clamped into sealing engagement therewith by the clamping force of the bolt.
