Title: Multilayer fleece fabric
IPC: D04H1/68
Filed: 1973-12-12
Abstract: 1418227 Coated fabrics CARL FREUDENBERG 12 Dec 1973 [12 Dec 1972] 57573/73 Heading B2E [Also in Division B5] A fabric impregnated with a bonding agent comprises a plurality of superimposed layers of fabric, the fibres in each layer having a general direction in the plane of the fabric which is different from that on the or each adjacent layer, wherein there at least two adjacent layers with different fibre compositions, one surface of the fabric carrying a coating of a thermoplastic adhesive. The fabric preferably comprises three layers, the general direction of the fibres in the outermost layers being the same, the general direction of the fibres in the middle layer being from 45 to 90 to the direction of the fibres in the outer layers. The fabric may be produced on an installation consisting of three roller or flat cards, two of which supply fleeces in which the fibres extend in the same direction i.e. the direction of production and the third of which supplies a fleece which is cross-lapped as the middle layer between the other layers, the resultant tri-layer composite being impregnated with a liquid (e.g. foamed) binder and dried. Suitable fibres for the fabric are of cellulose, cellulose acetate, cellulose triacetate, regenerated cellulose, polynosic, polyamide, polyester, polyacrylonitrile. The binder may be a polyacrylate, a carboxyl group containing acrylonitrile-butadiene copolymer or an acrylonitrile-butadiene copolymer which is self-cross-linking in an acid medium. The adhesive coating may be of polyethylene, polyamide, polyurethane or PVC and may be applied in a geometrically regular or irregular pattern e.g. by printing a pattern of dots.

Title: Bearing indication system for digital measurement of azimuth
IPC: G01S13/78
Filed: 1967-12-20
Abstract: 1,146,559. Radio navigation. INTERNATIONAL STANDARD ELECTRIC CORP. 20 Dec., 1967 [23 Dec., 1966], No. 57883/67. Addition to 1,102,332. Heading H4D. Specification relates to a modification of the radio bearing indicating system of Specification 1,102,332, wherein the radio beacon of that Specification, radiating pulses both directionally and omnidirectionally, is replaced by a secondary radar system of the type wherein for side lobe suppression, pulses P 2 , Fig. 2a, are radiated omnidirectionally and interrogating pulses P 1  and P 3  are radiated by a rotating directional beam. When received at a co-operating responder station the three pulses are compared in amplitude and only when pulses P 1  and P 3  are greater than pulse P 2  is it determined that the pulses P 1  and P 3  are being received by the main directional beam and not by its side lobes. For the invention the secondary radar further radiates a characteristic pulse N, Fig. 2d, omnidirectionally when the main directional beam passes through North. In the responder station, Fig. 3, counter 28, counts pulses P 2  between the reception of the N pulse and the passage of the main directional beam, and counter 31, counts pulses P 2  between the passage of said beam and the next N pulse. The total count in the two counters represents 360 degrees and by a ratio determination the counts can give the bearing of the station. A received N pulse at 27 thus resets counter 28 to zero which commences to count the P 2  pulses from detector 24 via gate 29, until said gate is inhibited by a 1 state of bi-stable circuit 25 caused by the detector determining that pulse P 1  is greater than P2 and that the main directional beam is passing the station. Said 1 state resets counter 31 which also commences to count the P 2  pulses from detector 24 via gate 32, until said gate is inhibited by the next N pulse.

Abstract: 1383514 Textile apparatus for coating TETRA PAK DEVELOPPEMENT SA 29 Sept 1972 [22 Dec 1971] 59641/71 Heading D1L [Also in Division B8] Web material advancing along a serpentine path between successive rollers which grip the web between them is initially fed to the rolls using roller apparatus comprising means to move at least one roller away from and towards neighbouring co-operating rollers to provide between the thus separate rollers a substantially free open path through which the web is lowered in a substantially vertical direction and gripped between the rollers in the desired path when the movable roller or rollers is or are restored to cooperative working relationship with the other rollers. The apparatus is preferable used in conjunction with conventional coating devices for coating e.g. with plastics, both sides of a paper web. To effect movement of the roller or rollers the latter may be mounted on shafts between the ends of pivoted lever supports or the roller or rollers may run on shafts mounted in a slidable frame whereby the rollers can be moved apart and brought together. As shown in the Figure, in frame 1 between opposite side walls are mounted a series of parallel co-operating rollers between which the web 9, passes i.e. guide rolls 2, 3, a tension roller 4, three rollers 5, 6, and 7 in contact with the serpentine web, and an outfeed roller 8. The shaft 10 of roller 5 is mounted between the free ends of two levers 11 pivotably attached to frame 1. Similarly shaft 13 is mounted on levers 14 pivoted at 15, and shaft 16, on levers 17 pivoted at 18. If desired the shafts of the guide rollers 2, 3 may be mounted between levers 19 pivoted at their mid-points 20 to brackets on an extension of frame 1. Tension roller 4 may be mounted between fixed bearings 21 on frame 1. The web is threaded into the machine by swinging levers 14 counterclockwise whereby roller 6 is withdrawn from rollers 5 and 7, lowering roller 5 by counterclockwise rotation of lever 11, and swinging lever 17 clockwise to move roller 8 whereby a vertical path is opened between rollers 6 and 8, and 5 and 7 through which the web is fed. When the web has been inserted the pivoted levers 19, 11, 14 and 17 are swung to bring the rollers back into their cooperative working positions. In a Figure (not shown) the rollers are moved in slidable frames. Both figures include two extruders positioned to coat both sides of the web with a plastic material.
