Title: Improvements in or relating to the manufacture of hollow metal bars
IPC: B21B23/00
Filed: 1928-02-07
Abstract: 290,951. Bedford, R. A. Feb. 7, 1928. Cores.-In the manufacture of hollow metal bars, such as of tool steel, by rolling a hollow billet on a core of ductile metal such as copper, as described in Specifications 115,688 and 185,639, the core, after insertion into the billet is compressed therein prior to rolling so as to avoid the tendency of the billet during rolling to produce blind or waste ends. The hollow billet is heated and a. cold core of sliding fit is inserted therein; its length being sufficient to protrude from the billet substantially equally at each end. The billet is then placed in a mechanical, hydraulic, steam or pneumatic press and the core compressed longitudinally so as to expand it radially and press it into internal contact with the billet hollow. The protruding ends are received in collars or guides to prevent them from bending during compression. Two rams may be used moving towards one another in the guides, or one ram may be used co-operating with a support for the other end of the core. In the latter case the pressure may be applied in stages and relative movement of the support and billet effected after each stage. The core may alternatively be compressed by hammering. After rolling, a length of the bar is fractured and removed from each end of the core which is then gripped in order to extract it from the bar.

Abstract: 1464528 Stapling; drafting; sliver formation SCHUBERT & SALZER MASCHINENFABRIK AG 29 Jan 1975 [5 Feb 1974] 3807/75 Headings D1F and DIN A method of producing slivers of staple fibres from at least one band K of continuous fibres comprises applying the band of fibres to a carrier 2 and fixing the band on needles 21, moving the band of fibres, fixed on the needles to a cutting point; cutting the band of fibres fixed on the needles between two rows of needles, the rows being at an angle to their direction of travel and removing the sections severed from the band of fibres from the needles and delivering them in an ordered manner. In the embodiment of Fig. 1 the rows of needles are carried on needle bars 22 which are guided in slots 24 which extend radially in the circumferential surface of roller 2. The needle density is greatest at each end of each row. The needle bars 22 have heads 23 which run in stationary camming guides 25 which lie on both sides of roller 2 and are so formed that the rows of needles 21 gradually emerge from the body of roller 2 after the band K has been deposited under tension, gripping the band of fibres and lifting it clear of the roller 2, on supporting plates 26, by the time the cutting station is reached. The cut is made by a circular knife 11 rotatably mounted on cutter head 1. In the embodiment of Fig. 2, not shown three circular knives are spaced around the circumference of head 1. After the cutting station the camming guides gradually retract the needle bars 22 into the roll 2 until, when the delivery point a is reached the tips of the needles have been retracted. Air may be blown from the inside of roller 2 through slots 24 to assist in the removal of the fibres from the needles. Belts 3 and 33, which convey the sections of the fibre band, move at a slower speed than roll 2 so that the sections are compressed together. The compressed sections are drafted at 4, formed into a sliver at 41 and the sliver passed through stuffer box 42. In the embodiment of Fig. 8, not shown a second pair of belts (9, 91) is inserted between belts 3, 33 and drafting rolls 4. Belts (9, 91) form a downwardly converging funnel. At the bottom of the funnel they run horizontal at right angles to belts 3, 33. Vertical guides 8, 81, Fig. 7, may be provided by the upper run of belt 3, guide 81 moving in the same direction as the belt. If belt 33 is dispensed with plates 8, 81 may extend to the end of belt 3. In the embodiment of Fig. 6 rows of needles 64 with supporting plates 65 are carried by endless belt 6 which moves around rollers 61, 62, 63. A second belt 7 moves around rollers 71, 62, 63 and has slots through which the rows of needles protrude as the belts come close together. Mixed slivers can be produced by using a plurality of feed bands of continuous fibres.

Title: Improvements relating to the extraction of fibres from hard-leaved plants

Filed: 1942-04-09
Abstract: 555,163. Obtaining cellulosic fibres. WESTMAN, K. E., and STRAUSZ, H. J. April 9, 1942, No. 4686. [Class 2 (ii)] Fibres are obtained from the leaves of hardleaved plants such as Colombian pita, by treatment with alkali in the presence of an oil and a petroleum sulphonate. The alkali is of sufficient concentration to soften the tough skin and binding substances of the leaves but it is prevented from attacking the fibres owing to the presence of the oil and petroleum sulphonate. The freshly cut or dried leaves may be treated in an autoclave at elevated temperature and pressure with a solution of sodium carbonate of 5-10 per cent. strength containing an addition of a mixture of nearly neutral petroleum sulphonates, paraffin oil or kerosene, water, and ethyl alcohol. This addition has a softening effect on the fibres in addition to its protective effect. The treated leaf material is washed and may then be passed between roughened or corrugated rollers which press out most of the moisture. The leaf material is then passed through scraping and combing machines which separate out and comb or card the fibres and prepare them for spinning.
