Abstract: A vessel for receiving material from an area of total containment, such as a glove box, provided with an integral filling tube through which the material is transferred, the filling tube being capable of passing through a sphincter valve and of being constricted to the point of severance to obtain simultaneous sealing at both ends of the disjunction.

Abstract: An apparatus for the continuous treatment of an advancing web such as a cotton fabric with one or more reactive gases comprises one or more reaction chambers, each including fluid dicharge means for directing a treating gas onto the web in the chamber and evacuation means disposed on both ends of the chamber to prevent both the fluid from escaping from the chamber and the fluid outside the chamber from entering the chamber. Heating means adapted to heat the continuously advancing web of fabric material may also be provided, if desired.Such an apparatus may be used for the application of gases such as ammonia to a fabric impregnated with monomeric tris (hydroxymethyl) phosphine to form on the fabric a polymerized phosphorus-containing material and to impart flameproofing properties thereto. The apparatus can also be used to apply gases such as formaldehyde or sulfur dioxide or both to a cellulose fiber-containing fabric at an elevated temperature and in the presence of controlled amounts of moisture.

Abstract: This application describes a tubular container wall material of particular use in the packaging of dry and liquid products such as hydroscopic food products, and liquid foods. This wall material comprises an inner portion of liner ordinarily composed of four adherent plies of polyester-polyolefin-metal foil-heat seal coating-which liner bonds through the heat seal coating to an outer portion of rigidity-imparting material. This composite wall material constitutes the tubular wall for a container and is formed by winding elongate strips of its constituent plies onto a mandrel where they are bonded into an integral structure, for example, by heating. The can or container itself may then be formed by cutting the resultant tubular structure into appropriate lengths and attaching end closure means thereto.

Abstract: A liquid agitator having agitator blades attached to a rotary shaft centrally located within a liquid containing vessel is provided with a vibration suppressing stabilizer, consisting of one or more plates attached to the agitator shaft. The span of the stabilizer is somewhat less than the diameter of the agitator blades, but equal to at least about 20% of the blade diameter. The height of the stabilizer is also equal to at least about 20% of the blade diameter. The stabilizer is located in a portion of the liquid within the vessel which rotates about the agitator shaft with a tangential velocity proportional to the distance from the shaft. Interaction between this liquid and the stabilizer suppresses agitator vibrations.

Abstract: A non-contacting shaft seal for preventing the flow of fluid through a shaft passageway in a housing wall includes a collar fixedly attached to a rotating shaft for creating a zone of turbulence around the passageway. The collar has a diameter larger than the diameter of the shaft passageway and is slightly physically spaced from the housing wall to confine the turbulence to the area between the collar and the housing wall to thereby create a generally annularly shaped zone of turbulence or turbulence barrier around the passageway.

Abstract: A seal for fluid tight sealing between a shaft and a member having an opening through which the shaft extends. The member includes a sealing surface perpendicularly disposed to the shaft axis and the seal is of a homogeneous "right angle" construction having hub and flange portions. An inwardly extending continuous lip establishes a seal between the hub and shaft, while an annular ridge defined on the flange engaging the member sealing surface sealingly engages the surface whereby a sealed relationship exists between the shaft and member regardless of the presence of eccentricity therebetween during shaft rotation or linear displacement. Seal positioning means maintain the flanged ridge in engagement with the member sealing surface and annular spring means are employed upon the hub to bias the lip into engagement with the shaft.

Abstract: A fluorescent lamp has a phosphor coating on the inner surface of its glass envelope. The phosphor coating contains a small amount of barium carbonate admixed therewith. The barium carbonate improves the light output maintenance of the lamp.

Abstract: An automatic apparatus or robot preferably intended for cleaning floors or like surfaces in such premises and within such regions, where one cannot for special reasons utilize conventional apparatuses or machines. The automatic apparatus or robot includes a unit which is spaced from the apparatus proper, drivable along a track spaced from the floor or like surface, and coupled with the apparatus to steer and tow it.

Abstract: A seal engageable with the outer surface of a shaft and fittable within an inwardly open groove formed in a housing between a high-pressure zone and a low-pressure zone has a cup packing integrally bonded to a supple pressure-distributing ring. The packing is of asymmetrical section and is formed with a radially extending flange and with a lip extending from one axial side of the flange toward the high-pressure zone with the inner face of the lip lying resiliently against the outer surface of the shaft. The pressure-distributing ring has an end surface bonded to the one side of the flange, an inner periphery formed with a recess snugly receiving and bonded to the outer face of the lip, and an outer periphery resiliently engaging the interior of the housing groove. A nonresilient antiextrusion ring is received in the packing at the other axial side of the packing.

Abstract: Process and apparatus for the pattern dyeing of moving pile fabrics such as carpets, by the application of plural, continuously flowing dye streams, wherein the dyes are applied in multiple discrete small increments from the streams and control means are provided for accurately positioning the points of application of the dye increments in the pile fabrics to obtain sharp, detailed intricate patterns.

Abstract: A porous seal element usable as a blade tip seal in a turbomachine or as an element of a labyrinth seal is made up of a large number of strips disposed edgewise to the sealing face of the element and extending in the direction of relative movement of the seal elements. The strips have grooves extending across the strip for discharge of a cooling fluid such as air. The presence of the grooves provides a low density structure at the seal face of the seal element which may be abraded if there is rubbing contact and provides for metering of coolant at the rear face of the seal element. The seal element is fabricated by etching sheets so each sheet defines a number of parallel strips joined by weak ties and with the grooves extending across the strips; stacking the sheets and bonding them together; and then separating the bonded structure at the weak ties so that each stack of strips defines a seal element.

Abstract: A process for the concentration of pigment press cakes including feeding the press cakes to rollers and simultaneously applying a vacuum.

Abstract: The pressure springs for biasing the yoke and sleeve against the packing are mounted within an assembly unit formed by an annular carrier and a cap nut. The cap nut is threaded onto the housing while the annular carrier carries two bolts which pass through the yoke. Upon turning of the nuts on these bolts against the yoke, the annular carrier is moved toward the yoke to compress the springs while the yoke and sleeve are moved against the packing to compress the packing.

Abstract: A unitized dual lip seal for providing a seal between a housing and a shaft extending through a bore in the housing, including (1) a wear sleeve connected to the housing and having an inwardly extending radial flange, and (2) an elastomeric member mounted on the shaft with a main sealing lip riding on the inner wall of the wear sleeve on one side of the radial flange and an auxiliary lip on the other side of the radial flange and riding on the outside face of the radial flange. The umbrella-like auxiliary lip prevents formation of a pocket of contaminant and also encourages water drainage to wash sludge away from the auxiliary lip.

Abstract: Mating members, one rotating, the other stationary, each have grooves in facing annular surfaces for receiving rings, some of which rings carry seal strips and other of these rings define lands for engagement by the seal strips. All of the rings are held in place by elongated fasteners extending through aligned openings in the seal rings and in the land defining rings respectively, which fasteners serve to hold these rings in the associated grooves.

Abstract: A screw for injection molding of synthetic resinous material having a tendency to abrade and score the injection molding apparatus is provided along a substantial length of the feed section with a substantially undercut screw flight. An average particle of synthetic resinous feed stock material may pass between the undercut screw flights and a cooperating barrel without squashing. The undercut screw flights are effective to provide a controlled feed pressure for the particulate material entering the downstream portion of the screw.

Abstract: An improved pipe cap comprises a cover and a U-shaped handle pivotally connected thereto. The handle includes a pair of rounded lugs which are adapted to engage an annular groove in the pipe end when the pipe cap handle is rotated toward its locking position. When the handle is rotated away from the locking position and towards the unlocking position, the lugs cooperate with the groove so as to cam the cover off of the pipe end. This novel camming action helps to overcome the resistance frequently associated with breaking the seal between a pipe end and a pipe cap.An alternate embodiment of the improved pipe cap is fitted with lugs having a pronounced flat on one side. The alternative cap is intended to fit on a pipe adapter having a flat locking rim instead of a groove. The rim includes two slots 180.degree. apart which are engagable by an appropriate wrench to thread the adapter onto a fill pipe. The lugs on the cap are located in such a manner that at most only one lug can fall into a slot.
