Title: Improvements relating to the manufacture of axminster carpets and like tufted pile fabrics
IPC: D03D39/02
Filed: 1938-09-15
Abstract: 518,992. Looms. SOUTHWELL, Ltd., H. & M., and HEAD, F. W. Sept. 15, 1938, No. 26874. [Class 142.(ii)] In the production of Axminster carpets and like tufted pile fabrics with a ribbed back surface, two weft inserting needles or carriers N<1>, N<2> are used in staggered relation and on either side of a supplementary slay S<1>, the lower one being nearer the fell of the'fabric. In Fig. 1, A represents the stuffer warp and B, C the chain warps which form sheds above and below warp A. S<2> represents the main slay. After the needles have been withdrawn the slay S' moves forward to beat up the weft W<1> inserted by the needle N' and then falls to a resting position as shown in Fig. 2. The upper weft thread W<2> inserted by needle N<1> is meanwhile held back, thereby leaving space for insertion of the tuft yarn T through the warp threads. The slay S<2> then presses forward the weft W<2> while spool X is raised to leave sufficient tuft yarn projecting from the bottom of tubes T' for another insertion after severance of the yarn T. The slay S<2> then returns, the depending ends of the tuft yarn are turned up by a comb or under reed and the warp C takes the place of the warp B, which falls to a lower position (Fig. 4). The needles N<1>, N<2> are again inserted, but the slay S<1> remains at rest, while the weft W<3> carried by the needle N' is inserted into the upper shed and beaten up by the slay S<2>. The warp C then falls to form a lower shed, the warp B rises and the operation is repeated.

Title: Improvements in or relating to the preparation of magnesium
IPC: C22B26/22
Filed: 1934-09-21
Abstract: 444,957. Distilling magnesium. KIRSEBOM, G. N., 3, Osborne Road, Clifton, Bristol, and CALLOY, Ltd., 95, Gresham Street, London. Sept. 21, 1934, No. 27209. [Class 82 (i)] Magnesium is prepared by heating in a closed vessel to a temperature above the volatilization of magnesium, an aluminiummagnesium alloy in which the alloy is preponderating proportions and condensing the magnesium vapour given off. The aluminiummagnesium alloy may be previously formed as described in Specification 397,844 or may be formed in situ by heating magnesium oxide and aluminium in a closed vessel at a temperature above the boiling point of magnesium, but below the boiling point of aluminium, the magnesium oxide being in pieces of sufficient size to overcome the surface tension of molten aluminium, e.g. pieces in size from 1-100 mm. The process is carried out in a high frequency electric furnace and the reduction process is carried out at a temperature above but in proximity to the boiling point of magnesium, e.g. 1120-1200‹C. In one form of the reduction process, calcined magnesite, which may be briquetted with carbon, is charged into a crucible and covered with a loosely fitting graphite cover and molten aluminium poured in before the heating takes place. The process may be carried out in a graphite crucible 3 mounted in a furnace 1 heated by an oil jet, the crucible being covered by a graphite lid 4 secured in position by sintering 5. In the latter is provided an opening 6 in which is fitted a condenser pipe 7 arranged at such an angle that the metal vapour condensed to liquid will flow and drop into a receiver 9 placed under a hood 8 secured to the lower end of the pipe 7 . and standing in an oil bath 13. The receiver 9 is in two parts held together by a tray 10 and ring 11, the tray 10 standing on a tray 12. A tube 14 is fixed in the side of the hood 8 in line with the tube 7 and is provided with a gland 17 through which a rod 15 passes, by which the pipes 7 and 14 may be cleared if clogged, an oil seal being provided at its lower end. A narrow inlet pipe 16 closed with a valve or rubber tube and clip is provided in the pipe 14, enough air being allowed to enter through this pipe after the end of the operation to prevent oil being sucked up into the hood 8. Instead of the oil tray 13, the hood 8 is closed at its lower end by a clamped disc and is provided with a U-shaped side tube dipping into an oil bath.

Title: Display system with circle drawing

Abstract: 1359674 Cathode-ray tube displays ELLIOTT BROS (LONDON) Ltd 9 June 1972 [11 June 1971] 27430/71 Heading HAT In a cathode-ray tube display curved lines are approximated by a succession of adjoining straight lines. Two embodiments are described. In the first (Fig. 1) the beam of the display tube 15 is deflected in incremental steps in the X and Y directions to trace each of the straight lines (e.g. the sides of a polygon when the curved line is a circle) under the control of incremental quantities contained in a Read Only Memory, ROM and in the second embodiment (Fig. 2, not shown) the tube beam is deflected raster wise and the incremental quantities from the ROM are employed to control the instant of beam bright-up to produce a succession of bright points the lengths of which may be varied to form elements of the straight lines. As shown in Fig. 1 (which is concerned with the tracing of a 100 sided polygon to approximate to a circle) the five most significant bits in an eight bit radius register R1-R8 define the length of a side of the polygon this number being compared in comparator 20 with the output of a (side) length counter L1-L5 driven by timing signals at input 10 and the output of the comparator on equality of inputs supplying a signal via gate 22 which resets counter L1-L5 and "clocks on" a side counter S1-S5 by one count. The count in the latter is decoded by circuitry 24 and causes the ROM to supply the incremental deflection quantities DX1, DY1 for the next side to gates 11, 12 through which they are supplied on the occurrence of the timing signals to the beam deflection circuitry. Since the polygon is symmetrical wirh respect to the 45 degrees axis DX, DY incremental quantities need be stored for only 13 sides in ROM, a quadrant counter Q1-Q2 controlled by the overflow of the side counter S1-S5 controlling the memory output circuit 27 to set the sign of the incremental quantities in accordance with the particular octant in which the display is being produced. The lengths of all sides or of selected sides of the polygon and hence the size of the polygon may be varied under the control of the three least significant bits R6 to R8 in the radius register by comparing the latter in circuit 25 with the count in the side and quadrant counters and employing the output to block gate 22 and thus prevent line length counter from being reset until the desired length has been traced.
