Abstract: 718,406. Vinyl, resin-coated knitted fabrics; compound sheet material. CLAYTON, T. A. (United States Rubber Co.). July 11, 1952, No. 17481/52. Class 140. A composite stretchy upholstery material suitable as a leather substitute comprises a plain knit fabric with 35 courses per inch when it leaves the knitting machine, having a thermoplastic vinyl resin film 0.005 inch 0.030 inch thick bonded to one face, which has a stress of more than 10 lbs. per inch at 5 per cent elongation, and less than 35 lbs. per inch at 10 per cent elongation in the wales direction, and preferably, more than 5 lbs. per inch at 5 per cent elongation and less than 25 lbs. per inch at 15 per cent elongation in the courses direction. A Jersey net of yarns of cotton, nylon, rayon, polyacrylonitrile, or copolymer of acrylonitrile and vinyl chloride having the same number of rows longitudinally and transversely, and having yarns large enough to fill the fabric loops, is knitted on a circular machine, the resulting tube is slit and the edges sized. This net, under tension of 3-5 lbs. per inch width, so that the stretch is less than 15 per cent, is calender skim-coated on the back so that there is no undue penetration into the interstices. As shown, bank of resin R between rolls 13, 14 is calendered to sheet 5, which is reduced to the desired thickness by rolls 14, 15, and pressed on to net 10 by rolls 15, 16 adjusted to an opening of 0.045 inch. The net is pre-heated to 250-325‹ F. by passage over a heated drum before coating. Rolls 13, 14, 15 are heated to 300-350‹ F. and roll 16 to 250‹ F. The coated fabric may be printed and embossed under the same tension. The resin composition may be polyvinyl chloride plastisol with 50-80 parts plasticizer, e.g. dibutyl phthalate, with or without a non-migrating polyester plasticizer, and stabilizer, filler, and pigment. The polyvinyl chloride may be substituted by a copolymer of vinyl chloride with vinyl acetate, vinylidene chloride, or diethyl maleate, or polyvinylidene chloride, or a combination thereof. The resin may be applied, however, as a fluid organosol by roll and doctor knife, or reverse roll coater, or a resin film separately prepared by calendering or casting may be adhered to the fabric, which may be adhesive-coated by passage through doubling tolls in the heated state.

Title: Improvements in or relating to optical maser systems
IPC: H01S3/104
Filed: 1964-04-28
Abstract: 1,061,613. Lasers. SIEMENS & HALSKE A.G. April 28, 1964 [April 30, 1963], No. 17495/64. Heading H1C. A tube 1 contains a gaseous active medium such as neon the atoms or molecules of which are raised to a chosen energy level by collision with electrons freed by ionising either the active medium or a second gas, the free electrons being propagated electromagnetically along the tube with controlled uniform velocity. In the single gas embodiment electrons are liberated by applying a D.C. potential to electrodes 15, 16 'the electrons liberated by ionisation being propagated along the tube by a travelling wave field produced by alternating current in a spiral delay line 2, as shown, or in a waveguide. The electron velocity is so chosen that the kinetic energy yielded up by a free electron upon collision with an atom or molecule of the active medium is substantially equal to the specific energy required to excite the atom or molecule to a chosen level of population inversion. The current in wire spiral 2 is applied and withdrawn by respective coupling coils 3, 4 connected to an H.F. generator 7 and a terminal resistor 8. The tube has its ends closed by transparent end plates 9, 10 inclined at the Brewster angle to the axis of stimulated emission 13, external mirrors 11, 12 one of which is partially transmitting completing the assembly. The electrodes 15, 16 are not necessary in a second embodiment in which a second gas such as argon is used. The second gas is selected to have a lower ionisation potential than that of the active medium, and ionization is effected directly by the field of the wave travelling along the spiral 2.

Title: Loudspeaker system
IPC: H04R5/02
Filed: 1962-05-07
Abstract: 981,729. Stereophonic systems; loud-speakers; acoustic reflectors. D. K. GREENFIELD. May 7, 1962, No. 17506/62. Headings H4J, H4R and H4X. A stereophonic loud - speaker sys - tem comprises a central loudspeaker unit located between a pair of flanking loud-speaker units, the units all being arranged to direct sound away from a listening area towards a plane reflecting surface and each unit being sufficiently close to its adjacent reflecting surface for the sound waves from the unit to diffuse across the whole reflecting surface and to merge with the sound waves from the other units. A reflected wavefront is obtained such that the aural impression and perspective are substantially constant throughout the listening area. A stereophonic system comprises a central enclosure 20 (Figs. 1, 3) housing two loudspeakers 27 and two flanking enclosures 21, each housing a loud-speaker 26. The enclosures 20, 21 are close to a vertical wall 22. Audio-frequency signals from a source 36 are applied by cables 37, 38 to amplifiers 39, 40 and the entire frequency spectrum outputs of amplifiers 39, 40 are fed to loud-speakers 27. A capacitor (Fig. 4, not shown) restricts the signals applied to loud-speakers 26 to frequencies above about 200 to 250 cycles/second. The central enclosure 20 (Figs. 6, 7) comprises two symmetrical chambers separated by a partition 58 and a barrier 61 of resin impregnated glass wool which absorbs high and mid-range frequencies. In the bass frequency range the energy absortion decreases with decreasing frequency so that the back wave radiation from each loud-speaker increasingly loads the other. Reflexing ports 57 are provided. Barriers 60 of resin impregnated glass wool smooth the response below 40 cycles/second and absorb high and mid-range frequencies. One side panel 53 is shorter than the other side panels 50, 51 so that when the enclosure 20 is placed on the floor a third chamber is formed, together with a slot out of which the sound issues. Alternatively a bottom panel may be provided, the third chamber being formed between panel 54 and the bottom panel. The output of enclosure 20 is restricted to bass and mid-frequencies by the restricted volume of the third chamber, by the rear slot, by the restricted volume between panel 53 and wall 22 and by carpeting. The flanking enclosures 21 (Fig. 10) are identical. They are completely lined with absorbent material. At the front a plate glass baffle 25 is secured at the top by a nylon strap 69 and a metallic clip 70, and at the bottom by two metal clips 72 and nylon straps (not shown). The central enclosure 20 may be located on the floor 33 (Fig. 3) concealed from view beneath and behind a cabinet 34 which houses the flanking enclosures 21. A plurality of loudspeakers may be located in each symmetrical compartment of enclosure 20. The enclosures may be concealed above ceiling level. Other concealed arrangements are described.
