Title: Non-woven fabrics
IPC: D01D5/253
Filed: 1968-04-01
Abstract: 1,215,537. Non-woven fabrics of continuous heterofilaments. CARL FREUDENBERG. 1 April, 1968 [31 March, 19671, No. 15569/68. Addition to 1,055,187. Heading B5B. [Also in Division D1] In a modification of the parent Specification a non-woven structure is made by extruding molten fibre-forming polymeric material through extrusion apertures, more than one stream, each of a different polymeric material being fed towards each aperture, and uniting the streams into a single multi-segment stream before extrusion. The apertures are arranged in one or more rows so that the extrusion results in the formation of one or more sheets of continuous filaments, which are stretched by gas streams forced out of slots one on each side of each row of apertures and adjacent and parallel to that row. The sheet(s) of filaments together with its associated gas streams are led through an open-ended duct through which the filaments and gas pass substantially without entanglement of the filaments, which are stretched and set whilst being kept parallel to but separate from one another. A fleece is formed by collecting the sheet(s) on a carrier. On extrusion, all filament segments of a single polymeric material are preferably similarly located with respect to the slots. In the spinneret shown, ridge 3 and lower part 2 define air slots 4 and 5. A row of apertures 6 are formed along the centre of the tip of the ridge and different polymeric materials are fed to them through polymer supply ducts 7 and 8 and emerge as heterofilaments 21, which are stretched and cooled by the air streams. They then pass down through an elongated duct near the top of which further air streams are applied to the filaments through slots 15. The apertures can be of circular shape or profiled or of other non-circular shape. With a C-shaped aperture the air streams tend to close the C-profile so that a heterofilament with a hollow cross-section is formed. Bicomponent filaments of similar chemical properties may be spun, e.g. nylon 6 and nylon 66, or polyethylene terephthalate and a copolyester of terephthalic acid/isophthalic acid or terephthalic acid/parahydroxybenzoic acid. These filaments can be crimped by a steam treatment when one component melts at a suitably low temperature compared to the other. Another combination is a polyamide such as nylon 6 or 66 and a polyester such as polyethylene terephthalate. Since the polyamide absorbs more water than the polyester, crimping of the filaments occur. The porosity of the non-woven structure can be increased by dissolving out one of the components of the hetrofilament from the structure. Examples of such heterofilaments are nylon 66 and a soluble copolymer of caprolactam, adipic acid, and hexamethylene diamine; polypropylene and soluble polystyrene; polyethylene terephthalate and a soluble copolyester of terephthalic acid and isophthalic acid.

Title: Improvements in or relating to processes for depositing coatings of aluminium or of aluminium-base alloys on a basis metal and for the production of pulverous aluminium-base alloys
IPC: C23C10/08
Filed: 1955-05-31
Abstract: A basis metal is coated with Al or Al-base alloy by treatment with vaporous Al sub-chloride (AlCl and/or AlCl2) which has been produced by reacting a vaporous chloride of a foreign metal (defined as a metal other than the basis metal and Al, and to include Si) with Al or an Alalloy at a temperature above 500 DEG C., the sub-chloride having undergone no cooling to below the temperature of the treatment of the basis metal between the time of its formation and the time it is used in said treatment. Preferably, the foreign metal chloride, which may for example be SiCl4 and/or TiCl4, is carried in a current of inert or reducing gas over the solid, or through the liquid, Al or alloy thereof, the sub-chloride thus formed being fed in the carrier-gas to the basis metal.  Suitable Al alloys for reaction with the foreign metal chloride are the aluminides of Si, Fe, Ni, Ti, Zr, and Mo.  Coatings may be formed on Fe, alloy steels, Ni, Cr-Ni alloys and Mo and alloys thereof.  Two specific examples of the process are given.  If the basis metal is in pulverous form it may be converted wholly into an alloy of the basis metal and Al by extended treatment with the sub-chloride.  An example discloses the conversion of Mo powder into Mo aluminide powder.

Title: Improvements in machines for spinning, doubling, twisting and the like, yarns, fibres, and the like
IPC: D01H1/10
Filed: 1929-05-21
Abstract: 338,570. Dunlop Cotton Mills, Ltd., Andrew, T. E., and Langstreth, M. May 21, 1929. Spindle apparatus; special yarns, producing; winding-machines. - In apparatus in which the yarn is withdrawn in the form of a loop from a rotating bobbin mounted on a fixed spindle so that two twists are imparted thereto for each revolution of the apparatus, the bobbin support comprises parts capable of relative movement so arranged that any tendency of the support to swing is reduced or prevented by the relative movement of the parts. With such a bobbin support is associated the means described and claimed in Specification 338,606 for effecting and maintaining the tension of the yarn. As shown in Fig. 1, the part 4 which carries the bobbin is pivoted at 5 to, the part 3 which is mounted in ball bearings on the rotating spindle 1; other arrangements may be used such as a link or chain connection between the parts, a pendulum weight carried by the support, if desired, flexibly, or balls or rollers adapted to move freely in a channel in the support. The part 3 is provided with a cap 21 with a sleeve 22 which projects into the interior of the spindle 1 and serves as a guide for the yarn as it. passes from the bobbin through the spindle to the guide disc 24. A ring 27 carried by a stationary part of the machine prevents interference of the balloons of yarn of adjacent apparatus, and a ring 28 carried by the bobbin support serves to hold the yarn clear of the bobbin when setting-up. The tensioning of the yarn is effected by the weight of the bobbin operating through a drag washer interposed between the bobbin and its support, and provision may be made to adjust or control the tension so that it remains constant during the unwinding of the bobbin, and so that it may be predetermined to suit any specified conditions; these means and the construction of the bobbin 39, Fig. 12, are the same as those described in the Specification above referred to. The arrangements may be used to the twisted yarn to a ring doubling-spindle, or a number of yarns may be twisted one round another to produce fancy effects, the tensions, counts &c. of the different yarns being arranged to give the required results. They may also be used to wrap an outer filament around a central core so as to provide insulation on a wire, as shown in Fig. 16. Specification 287,334 also is referred to.

[Also in Group XXIII] A chuck, particularly for screwing-up bolts, nuts or studs, has relatively-rotatable primary and secondary members 2 and 3 and the toothed jaws 6 have shanks 601 which pass through cam slots 101 in the cap 1 of the primary member to engage by means of rollers 602 in slots 301 in the secondary member; the backs of the jaws also bear on cam surfaces 102 corresponding to the cam slots. The jaws are opened by rotating the secondary member relatively to the primary member by an outer sleeve 4 which is connected to the secondary member by a pin 11 working in a notch 111 and, on release of the sleeve, a spiral spring 15 rotates the secondary member back until the cam surfaces cause the jaws to grip the work. When the chuck is rotated, either by a spindle engaging the taper shank 502 of the primary member or by a spanner on the squared portion 501, the jaws are pressed more tightly on the work, the driving torque being transmitted to the jaws through the cam surfaces. The chuck may be modified for rotation in the opposite direction, for unscrewing. In a modification, Figs. 7-14 (not shown), curved slots each having a rail on the upper and lower edge of the cam surface are provided in a plate forming the end closure of the primary body member, the jaws having claws which slide on the rails. The secondary body portion comprising a plate has outwardly-directed slots in which the shanks of the jaws can slide. The primary body has an external enlargement by which it is manually rotated to open the jaws, the relative rotation of the jaws being limited by a stud fixed to a disc attached to the secondary body and passing through an arcuate slot in a circular plate fixed to the primary body. In another modification, Figs. 15-20 (not shown), the jaws slide on cam surfaces in the cap of the primary body member and are each provided with a shank having two parts of different diameter. The parts of smaller diameter travel in guide slots in a plate attached to the cap and the parts of larger diameter in radial slots in the secondary body which is in the form of a spool.
