Abstract: 1345944 Coated filaments EI DU PONT DE NEMOURS & CO 2 Dec 1971 [3 Dec 1970] 56019/71 Heading B2E [Also in Divisions C3 and D1] A composite filament comprises a core of at least one continuous elastomeric yarn and a continuous sheath of a closed-cell polymeric foam modified in that walls of the cells contain microapertures, the core being under tension and the sheath being under compression along the fiber-axis of the composite filament when in unstressed condition. The composite filament is produced by feeding the elastomeric yarn through a zone in which it is held elongated under tension, applying a continuous coating of a foamable organic polymer composition thereto, flash-extruding the coated core so as to convert the foamable composition into a micro-apertured ultra-microcellular foam coating, and releasing the tension on the composite filament to allow the elastomeric core to retract partially and the sheath to be compressed longitudinally of the filament axis until a balance of forces is established, whereby the core is partially elongated and tensioned within its coating of micro-apertured ultramicrocellular foam. The microapertured ultramicrocellular foam is produced by a suitable adjustment of reaction conditions (polymer concentration, temperature). The synthetic polymer is preferably a polypropylene and the elastomeric yarn may be a spandex yarn. At least 50% of the cells in the foamed coating should preferably be interconnected by microapertures. The average microaperture area per cell is preferably at least and/or up to 50 microns. Preferably two or more cell walls per cell contain the microapertures, and generally the cells have an irregular polyhedral shape. The examples refer to coating polyurethane spandex yarn and a natural rubber core with a foamable composition comprising a linear propylene, methylene chloride and silica aerogel.

Abstract: 1283945 Aircraft display apparatus BOEING CO 14 Oct 1969 [14 Oct 1968] 50451/69 Heading B7W [Also in Division G1] Apparatus for aiding the pilot of an aircraft simultaneously displays information about a first operating parameter and a second operating parameter which is dependent upon the rate of change with time of the first. In the embodiment of Figs. 1 and 2, the apparatus is provided with a pair of rectangular windows 24 and 26. Within the window 24 is seen a movable scale 28 provided with logarithmically spaced markings denoting altitude of the aircraft, while within the window 26 is seen a stationary scale 34 bearing markings indicating the vertical speed of the aircraft. In one operating mode the altitude is indicated by stationary pointer 32 and the vertical speed by movable pointer 44. A further pointer 112 may be moved by means of knob 122 to indicate a specific altitude on scale 28, but will then move with the scale so that it will coincide with the pointer 32 when that altitude has been reached. In an alternative operating mode the pointers 32 are retracted and the scale 28 moves so that the actual altitude is indicated by the bifurcated end of pointer 44. The apparatus is provided with two alternative sources of data as to altitude and vertical speed; a barometric altimeter 48 and a radar altimeter 50. Switch 58 controls a mode selector 52 so that the pilot may choose the source of the altimeter signals controlling the motion of the scale 28. In the event of either an altitude or a vertical speed signal failing, means may be provided for lighting warning lamps and/or switching automatically to the other source. In another embodiment (Fig. 4, not shown, and Fig. 3), there are provided two concentric scales; an outer, movable, scale 158 having compass markings, and an inner, stationary, scale 162 having a pair of markings 164 and 165 denoting rate of turn. In operation a magnetic heading source (171) or alternatively a tone heading source (210), actuates a drive mechanism (172) which controls the motion of the scale 158, the actual heading being indicated by stationary pointer 166. A further pointer 180 may be moved by means of knob 182 to indicate a specific heading, but will then move with the scale 158 to coincide with the pointer 166 when that heading has been reacted. A movable pointer 190 is driven from a source (194) so as to indicate on the scale 162 the rate of turn of the aircraft.
