Title: Air jet loom with improved air guiding comb
Inventor: KOBAYASHI YASUSHI
IPC: D03D47/30
Filed: 1977-09-07
Granted: 1981-02-19
Abstract: The construction of the reed in a jet loom has a number of tooth components to form the channel for the weft carried across the loom in an air stream, with a passage in each component to allow the laid weft to pass out for beating in.  The row of tooth components is built up of primary or secondary units, adjacent to each other, so that a part of each opening builds up an air passage by the different steps of their contrasting cross sections.  The design gives a structured channel for the air carrying the weft to pass across the loom, increasing weaving speeds, and preventing the weft from being entangled with the warps forming the shed.

Granted: 1983-05-24
Abstract: A preform is formed by providing a substantially longitudinally continuous core member (10) and affixing it to a starting member (12). Particulate material is applied to the exterior surface of the core member to form an adherent coating (18) having an index of refraction less than that of the core member (10). The starting member (12) and the core member (10) are longitudinally translated while simultaneously applying the adherent coating (18) of particulate material to the core member to form a continuous and substantially homogeneous adherent coating of substantially uniform thickness. The composite so formed is simultaneously or subsequently heated to sinter or consolidate the applied adherent coating thereby forming a solid blank which may be heated to the drawing temperature of the material thereof and drawn to reduce the cross-sectional area thereof forming a substantially continuous optical waveguide, the core member (10) comprising the core while the consolidated coating (18) comprising the cladding of the optical waveguide. The adherent coating (18) may be sintered or consolidated to form a solid blank and thereafter drawn in a separate operation or subsequently drawn as part of a continuing operation. As an alternate, the optical waveguide may be drawn immediately following the sintering or consolidation step employing a single heating of the structure.
