[Class 98 (ii)] [Also in Group XXXVIII] A lined screen is used in copying a variabledensity sound - record by optical projection to form a multiple variable area record. Such a screen may be formed by a plurality of continuous lines or by series of projections or depressions extending in the direction in which the film moves. When projections are used, these may be in the form of lenses. The invention may be used in the production of a negative copy or, by employing any known reversal process, a direct positive copy may be made. Moreover, the invention may be used in the production of a block or clichÚ from which the record may be mechanically printed on to films or other carriers. If desired, the lined screen may be formed on the film 3 which, as shown in the Figure, is provided on one surface with a photographic emulsion 30 and on the rear side with the requisite lines or lenses 31 limited to the zone a representing the area over which the sound record extends, the area b being left free for the picture records. In an alternative form, Fig. 7 (not shown), the emulsion on which the pictures are to be recorded is disposed on the same side of the film as the line screen system 31.

Title: Process for roughening and matting filaments of polyethylene terephthalate
IPC: D06M13/165
Filed: 1954-07-29
Abstract: Rough matte filaments of polyethylene terephthalate, which has been produced by polycondensation in a high-boiling solvent therefor, are obtained by melt-spinning the polyethylene terephthalate while it still contains 5-30, preferably 7-12, per cent by weight of solvent, passing the resultant filaments, while still hot, through air for a short distance and through a bath comprising one or more cold organic liquids which are miscible with the solvent in the filaments but do not dissolve polyethylene terephthalate, highly stretching the filaments and then treating them with superheated steam.  The solvent may be diphenyl methane, diphenyl oxide, diphenyl, benzophenone or alphamethyl naphthalene.  The organic liquid used for the after-treatment of the filaments may be carbon tetrachloride, tetrachloro - ethylene, acetone or tetrahydro-naphthalene.  In the example polyethylene terephthalate, which still contains 10 per cent by weight of alpha-methyl naphthalene, is melt-spun in known manner and the resulting filaments containing solvent, while still hot, are passed through air for about 10 cm. into a bath of cold carbon tetrachloride.  The filaments are withdrawn from the bath, spooled, and highly stretched in the usual manner, and the stretched filaments, spooled on perforated rollers, are then treated with steam at 130 DEG  C.

Title: Device for encoding a list of terms
IPC: G11C13/04
Filed: 1968-05-10
Abstract: 1,223,008. Coding devices; displays. COMMISSARIAT A L'ENERGIE ATOMIQUE. 10 May, 1968 [19 May, 1967], No. 22296/68. Headings G5X and G5C. [Also in Division G2] In a coding device, an alphabetically arranged list of terms is disposed on a rotary disc 1 in the form of a spiral of constant pitch. On the other side of the disc, in opposite and back-toback relation, is disposed a list of the corresponding encoded indications, there being a window 14 for stroboscopically reading the terms while the disc rotates, and means also for reading the encoded indications, e.g. a bank of photoelectric cells. The terms and codes are present on strips 2 and 2<SP>1</SP> (Figs. 2a and 2b, not shown), fixed to the metal disc 1 by means of members passing through holes 6 (Figs. 2a and 2b, not shown), this also ensuring correct relative positioning of term and corresponding code strip. The length of the strip is equal to the pitch of the spiral. The disc 1 is mounted between the two arms of a U-shaped support 9, which is radially displaceable along bars 10 by engagement with a continuous chain 11. Windows (only one, 14, shown) permit observation of the term and code strips. The circumference of the sprocket 12 is equal to the pitch of the spiral, so that in one complete rotation of the disc, the window 14 in the support 9 moves from one coil of the spiral to the next. Observation of the terms may be achieved stroboscopically by shining a lamp 19 on to a mark 5 (Figs. 2a and 2b, not shown), e.g. of white paint, on each strip, and reading the reflected light intensity with a photo-electric cell 20 (Fig. 3a, not shown), the electronic apparatus 22 to 26 causing a synchronized flash from the tube 27, so permitting reading of each term at high speed. Instead of the mark 5, a hole 21 in each strip may be used (Fig. 3b, not shown). The keys 16 and 18 control the rotary motion of the disc, the speed being proportional to the displacement of the keys, this being achieved by means of a rack and pinion attached to a potentiometer incorporated in the motor supply (Fig. 4, not shown). As the speed of rotation decreases, a change from flashing to continuous light is effected by means of the circuit of Fig. 4. The code may be marked on the strip by photogravure, or by a magnetic recording technique, and closed circuit T.V. may be used for viewing.
