Title: Diversity system
IPC: H04B7/10
Filed: 1960-11-28
Abstract: 938,962. Diversity systems; duplex radio signalling. STANDARD TELEPHONES & CABLES Ltd. Nov. 28, 1960 [Dec. 1, 1959], No. 40760/60. Class 40 (5). A diversity communication system includes a first station comprising a transmitter coupled to a first antenna system having a radiation pattern including a plurality of spaced beams to radiate an output signal on each of the beams, and a second station comprising a second antenna system having identical characteristics to those of the first antenna system and a plurality of receivers each coupled to one of the beams of the second antenna system. As shown, a transmitter 3 feeds a pair of horns 7, 8, symmetrically disposed in a parabolic reflector 6 and excited in a 180 degrees phase relationship, as by the insertion of a half-wavelength section 13, to provide a resultant radiation pattern consisting of spaced beams 11, 12 giving angle diversity. At the receiving terminal, horns 18, 19 are arranged in a reflector 17 to provide a pair of spaced beams 22, 23 which co-operate with corresponding beams at the transmitter to feed respective receivers 24, 25, a half-wave section 26 being incorporated in one feed to provide the desired radiation pattern and compensate for the phase-shift introduced at the transmitter. The outputs of the receivers are combined at 27 and fed to a utilization device 28. A two-way communication system is described, Fig. 2 (not shown), using angle diversity but having dual polarized feed horns in the antenna so that transmission in one direction uses vertically polarized waves and in the other direction horizontally polarized waves. In a further arrangement, Fig. 3 (not shown), each antenna system contains two pairs of symmetrically disposed dual-polarized horns providing two-way transmission as in Fig. 2, and each terminal has a pair of transmitters transmitting on frequencies F1 and F2, respectively, and each coupled to one of each pair of horns so that the radiation pattern consists of four spaced beams arranged in two pairs each pair propagating a different frequency. Each terminal requires two receivers for the frequency F1 and two for the frequency F2, the outputs of the receivers being combined in conventional manner.

Abstract: 1,241,676. High shrinkage threads, yarns and fibres. FARBENFABRIKEN BAYER A.G. 5 Sept., 1968 [7 Sept., 1967], No. 42278/68. Heading B5B. High shrinkage threads, yarn and fibres are produced from acrylonitrile polymers or copolymers containing at least 50% by weight of polymerized acrylonitrile and mixtures thereof, by exposing the filaments obtained by a dry spinning process to temperatures of 110‹ C. to 160‹ C. in the presence of steam, followed by stretching in water and drying at temperatures below 100‹ C. Two methods of steam treatment are described: (1) a dry heat treatment of the wet spun material which preferably contains at least 15% by weight of water; and (2) a hot steam treatment of dry or only moist spun material. In a discontinuous process the wet spun material is introduced in a freely shrinkable state into a heated chamber and an atmosphere of steam is produced by evaporation of water in the material. Saturated steam under pressure may also be used in the pressure chamber particularly when the spun material contains little or no water. The process may also be carried out continuously using as transport elements, drum sieves or rollers having different speeds of rotation, or belts. The steam treated thread may be stretched to 180 to 320% of its initial length, prior to being shrunk by steam, in water at temperatures below 100‹ C.. In the examples stretching temperatures of 75‹ C. and 85‹ C. are used. The polymers are obtained by copolymerization of acrylonitrile with one or more copolymerizable mono-olefinically unsaturated monomer such as methacrylonitrile, vinyl chloride, vinylidene chloride, vinyl bromide, styrene, α- methyl-styrene, esters of unsaturated carboxylic acids, vinyl esters, amides of monoolefinically unsaturated carboxylic acids, and the acids themselves, vinyl sulphonic acid, styrene sulphonic acid, m-methacryloylaminodiphenyldisulphide, N - N - dimethylhydrazide or vinyl pyridines. Inorganic and/or organic pigments such as TiO 2 , or colour pigments or soluble additives may be incorporated in the threads when spinning.

Title: Process for making variable denier yarn
Inventor: ALLEN FREDERICK CLIFFORD
IPC: D01D5/20
Filed: 1964-10-21
Abstract: Nylon or polyethylene terephthalate yarn is subjected to a first drawing operation in which the mechanical draw ratio is less than the natural draw ratio of the yarn at the drawing temperature so that, repeatedly, a localised drawing point or "neck" is formed along the length of the yarn at which the denier falls off with distance in the direction of advance of the yarn and that migrates in the direction in which the yarn is advancing, and yarn withdrawn from the first drawing operation which has relatively undrawn regions alternating with relatively drawn regions is then subjected to a second drawing operation in which the mechanical draw ratio is sufficiently low to avoid excessive breaking of the yarn or its constituent filaments. The yarn from the second drawing operation may be dyed with a dye that is sensitive to differences in the degree of molecular orientation in the yarn polymer to give the yarn a variegated appearance, alternatively it may be dyed with a disperse dye which is insensitive in this respect.
