Abstract: Abstract of the Disclosure A slide-fastener stringer half comprises a knit tape hav-ing a plurality of parallel longitudinally exte ding wales and a plurality of transversely extending courses, and a monofilamentary coupling element on the tape and having a succession of turns each having a pair of shanks and a coupling head joining the shanks and projecting transversely beyond the longitudinal edge of the tape.          The shanks of each turn lie at least in regions adjacent the res-pective head in a plane generally perpendicular to the tape.  The tape comprises at least one post shrunk warp yarn forming a chain knitted into the tape at every other course and overlying the shanks at the regions adjacent the heads.  Thus the shanks are laid into the chains at these regions so that the coupling element is thoroughly integrated into the knit of the tape.  The tape itself may be formed of a full-tricot ground.  Alternatively the tape can be formed of second warp yarns having open loops at each course and extending transversely each over two respective wales.

Abstract: CERAMIC TURBINE SHROUD ASSEMBLY                          Abstract A high temperature turbine shroud assembly for an aircraft gas turbine engine comprising a plurality of arcuate ceramic blocks arranged in a ring. The blocks are supported by a pair of annular support members which retain the blocks in the assembly. Spring-like fingers associated with the support members apply a preloaded force against a pair of slanted dove-tail surfaces on the blocks to force the blocks against rigid stops formed upon the annular support members, thereby establishing their proper radial position within the assembly. The preload applied by the fingers accommo-dates the thermal expansion differences between the ceramic blocks and the metallic support members. In an alternative embodiment, the blocks are retained between cooperating rigid legs extending from the annular support members and wedged radially inwardly into position by a preloaded spring contacting the back side of the blocks. Heat transfer between the blocks and metallic  support members is minimized by providing point or line contact between components, thus reducing the contact area available for heat conduction.

Abstract: ABSTRACT OF THE DISCLOSURE      A method of making endless power transmission belts each having at least a toothed outside surface is provided.  The method includes building a belt sleeve on a drum.  A polymeric material is extruded through an extrusion orifice to define a reusable cylindrical curing jacket having a toothed inside surface around the sleeve with the teeth thereof being disposed adjacent the sleeve.  The teeth comprising the toothed surface extend parallel to the longitudinal axis of the jacket.  The sleeve is cured with the jacket therearound while the jacket is subjected to pressure.  This causes the inside teeth to define corresponding outside teeth on the sleeve.  Upon cooling the jacket and sleeve, the jacket is readily removed for reuse, thereby substantially reducing the cost of providing a toothed outside surface on a belt sleeve and belts defined therefrom.          The sleeve is then cut to define the belts.  This therefore provides a simple and economical method of making endless power transmission belt having a toothed inside surface and a toothed outside surface.

Abstract: ABSTRACT OF THE DISCLOSURE         In a gearbox for an aircraft, a multiple stage separator is attached to a gear journaled within the gearbox housing.  An axial bore extends at least partially through the shaft supporting the gear and opens into a discharge chamber which communicates with an atmospheric vent.  A first stage of the separator includes an impeller attached to one face of the gear and a second stage includes a series of angularly spaced passages extending in a generally radial direction through the shaft to communicate with the bore.  A sleeve telescoped into a reduced section of the inner end of the bore receives the incoming mixture of air and oil and directs the air into an enlarged outer end section of the bore wherein final stage separation of air and oil occurs.  A member including an aperture concentric with the central axis of the bore keeps the oil collected along the walls of the bore from entering into the discharge chamber.  A passage defined by a flat formed on the outside of the sleeve provides a flow path in a direction away from the discharge chamber for the collected oil to exit the bore back to the interior of the housing.

Granted: 1981-08-25
Abstract: ABSTRACT OF THE DISCLOSURE        Ammonia synthesis processes are disclosed which provide enhanced conversion of hydrogen values to ammonia.  In the processes, a purge stream from an ammonia synthesis loop is treated to reduce its ammonia content to less than about 0.5 volume percent.  The purge stream is then contracted at an ele-vated pressure, preferably, at least substantially the super-atmospheric synthesis pressure of the ammonia synthesis, with the feed side of a separation membrane which exhibits selec-tive permeation of hydrogen as compared to the permeation of each of methane and argon.  A total pressure a driving force for hydrogen permeation through the membrane.  A hydrogen-rich permeating gas is obtained on the permeate exit side of the membrane.  The permeating gas is combined with gas passing to the ammonia synthesis reaction zone for conversion to ammonia.  For instance, the permeation gas can be com-bined with synthesis loop.  A non-permeating gas is removed from the feed side of the separation membrane at substantially the same pressure at which the purge stream is contacted with the separation membrane and provides a valuable source of energy due to its high pressure and combustible gas content.
