Abstract: 1,226,816. Composite filaments. LANSIL Ltd. 19 May, 1969 [20 June, 1968], No. 29451/68. Heading B5B. [Also in Divisions D1-D2] Composite, multifilament yarn is formed by introducing a synthetic, thermoplastic monofilament or multifilament yarn into a freshly formed, untwisted assembly of cellulosic continuous filaments, feeding the resultant untwisted yarn to a take-up package, twisting the yarn during, or separately from, such take-up, optionally inserting additional twist, and finally subjecting the twisted yarn to a texturing operation. The cellulosic filaments may be of cellulose acetate or triacetate and are "intimately blended" with or envelop the multifilament or monofilament yarn which may be of nylon, polyethylene terephthalate, polyethylene, polypropylene, or acrylic polymers or copolymers. The latter is introduced under tension at a point, e.g. the exit, within the spinning cabinet of a filament spinning machine whereat the extruded filaments have developed a dry and non-tacky outer surface.

[Also in Division F2] A flat machine includes a pair of take-down rollers, each comprising sections of short axial length which slip on their respective drive shafts when the resistance imposed by the fabric exceeds a predetermined maximum value. The fabric is pulled between the rollers by hooks 36. The draw-down roller comprises a series of toothed components 12, spaced to allow passage of the hooks, and arranged individually or in groups (see also Division F2). The components are pressed together to rotate with, or slip relative to shaft 10. The counter pressure roller comprises a series of short individual pressure rollers 21 on sleeves frictionally coupled to driving discs 26 of the shaft 11. The rollers take-down newly formed fabric across their full or partial width, and tension previously formed fabric as corresponding sections slip on the shafts. Pressure between the rollers can be varied. The hooks 36 slide in a frame 38 pivoted at 39 and spaced from a holder 43 by a vertically slidable roller 41. To prevent the teeth 12 prematurely disengaging loops from the hooks, roller 41 drops into recess 44 allowing the frame to swing the hooks towards rolls 21 as they descend. The hooks are disengaged by holder high 45 swinging the frame to the left. Slide 46 ensures the needles descend vertically.

Abstract: 1,239,283. Straightening; tensioning; flattening. NORD AVIATION SOC. NATIONALE DE CONSTRUCTIONS AERONAUTIQUES. 30 July, 1968 [31 July, 1967], No. 36393/68. Heading B3E. A method of flattening a metallic strip having blisters surrounded by strained zones is characterized in that lateral strains in the strip tending to widen the strip, are produced by the angular passage of the strip, under longitudinal stress over the working surface of each of at least two stationarily mounted rounded flattening tools acting successively on opposite sides of the strip, said lateral strains causing said blisters to be absorbed by compression of the blisters above their elastic limit. A sheet of hammerhardened stainless steel or niobium having a blister D (Fig. 4, not shown) when passed under tension over a radiused edge 2 of a tool the elastic limit under compression of the metal is exceeded in the blister itself so that it collapses and the sheet metal tends to widen and the blister breaks up into a multitude of smaller blisters by local buckling (Fig. 5, not shown). Protective sheets of an adhesive thermoplastic material may enclose the blistered sheet during the process and such sheets also act as a lubricant. Apparatus for carrying out the method comprises a block 5 made up of two parts 7, 8 pivoted together at 6 and locked in the working position by bolts 9, 10. Mounted in the parts 7, 8 are radiused tools 2a, 2b, 2c and 2d and a holding device R having friction shoes 11, 12 clamped by a screw 13. The tool 2d reduces the coiling effect which the tool 2b has on the strip. The block is mounted in a frame 15 provided with a supply roller 16 and a gripping device 18 for tensioning the sheet. The protective sheets 3b, 4b (Fig. 13) may be in the form of an endless belt supported and driven by rollers 27.

Abstract: 1,250,308. Luminescent screens. ZENITH RADIO CORP. 20 May, 1970 [4 June, 1969], No. 24417/70. Heading H1D. A luminescent screen for a colour television tube comprising a pattern of luminescent areas, e.g. dots as shown in Fig. 1, is characterized in that the areas are separated by dark areas formed by overlapping filters. In Fig. 1 red green and blue filters are deposited on the faceplate in the pattern shown so that the areas of overlap (shown cross-hatched) do not transmit visible light, and phosphors emitting the corresponding colours are deposited over the filters so that each effective light emitting area is a curvilinear hexagon, as illustrated at 11g, which is smaller than the corresponding aperture in the shadow mask with which the screen is to be used. Processing screens.-In a photo-resist method of manufacture a photo-sensitive slurry including powdered fusible material adapted to form a green filter is deposited on the face-plate and exposed through the shadow mask to form the green filter areas. The red and blue filter areas are formed by the same process, and then the phosphor areas are also formed by the same process, preferably using a shorter exposure time so that the phosphor areas are smaller than the filter areas. The screen is aluminized and the filter components will be affixed to the substrate either in a separate heat treatment step or during bakeout. In an electrostatic process the face-plate is covered with a conductive layer and a photo-conductor, both preferably being organic so as to be eliminated in bakeout. The screen is charged by a corona discharge and exposed to ultraviolet light through the shadow mask to form a latent image which is developed by the application of a toner. The toner may include both powdered filter material and powdered phosphor material in suspension so that both are deposited simultaneously, stratification being obtained due to the different densities of the materials. Alternatively the toner may contain only the filter material; after its application there will be sufficient residual charge left to allow the application of a second toner including the phosphor, or alternatively the phosphor may be sprayed over the first toner. Those combined filter and phosphor elements that overlie other filter and phosphor elements should be sufficiently thick that when the screen is in use the electrons cannot penetrate them to excite the underlying phosphor.
