Title: Method of manufacturing a textured yarn
IPC: D02G1/00
Filed: 1974-12-04
Abstract: 1485794 Texturing yarn by forming loops therein TOYO BOSEKI KK 4 Dec 1974 [6 Dec 1973] 52538/74 Headings D1F and D1W A method of manufacturing textured yarn, comprising feeding at least one continuous multi-filament synthetic yarn to a rotating spindle whilst simultaneously spreading the or each yarn into separated, individual filaments, wrapping at least some of the spread filaments around the spindle to form a sleeve enshrouding the spindle, continuously withdrawing the sleeve along the spindle axis at a speed lower than the feed speed of the or each yarn, and collecting the yarn obtained. Multifilament yarn 3, Fig. 1, is tensioned at 5, is spread into a bundle of separated filaments 9 by electrical, pneumatic or mechanical device 7, is wound on spindle 12 to form a sleeve 10 of superposed loops, and is withdrawn axially of the spindle so that the loops are elongated to form textured yarn 13. Guide 8 controls the bundle width. In Fig. 2, the sleeve is turned inside out by withdrawing the yarn 13a through the spindle. A balloon controller 21, Fig. 4, which may rotate may be used with solid or hollow spindles to depress a yarn balloon forming at the spindle nose. A core yarn is made by withdrawing the sleeve about a core thread fed axially through the mandrel, e.g. sleeve 10, Fig. 9, is withdrawn through the spindle about core thread 26 fed at a balloon-limiting angle alpha of less than 90‹. Those spaced filaments not fed to the spindle may be fed onto the rotating sleeve being withdrawn from the spindle, Fig. 12a, where a core thread may be fed through the spindle and the withdrawn yarn may be inclined to the spindle axis. Alternatively, spaced filaments 9-A, Fig. 15a, are fed to form a core, possibly with a core thread 26, Fig. 15b. The multifilaments may be first stretched between rollers 35, 36, Fig. 16, while being heated, and are then entrained by electrically non-conductive fluid 40, e.g. air, in ejector 39, and carried against changed porous plate 41 to be spread by the deflected fluid while being carried to the spindle. Alternatively (Fig. 17, not shown) the filaments supplied direct from an extruder are entrained in an air flow against an uncharged plate. Many spindle shapes are described. The angle between the surface and the axis of the spindle preferably does not exceed 15‹. The spindle may be made of metal, plastic, a ceramic, a jewel or glass, and may have a flange at its large end to prevent the sleeve slipping away from the spindle nose. The yarn may be heated, either continuously or in a package, to reduce resilient shrinkage and snarling characteristics. The or each multifilament yarn may be made of a polyamide, e.g. nylon, polyester, acrylic, rayon, acetate, triacetate, protein-acrylonitrile copolymer, benzoate, vinylon, polyvinyl chloride, polyethylene or polyvinylidene chloride. Many core thread materials and types are referred to. The core and sheath may be of different colours, or the core thread may be electrically conducting.

Abstract: 1,187,030. Photo-electric measurement of speed. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. Oct.24, 1967 [Nov. 30, 1966], No.53562/66. Heading G1A. The relative speed of a fluid or body is measured by directing two divergent coherent beams of laser radiation on to the fluid or body, causing the radiation backscattered from the two beams to interfer and measuring the rate of movement of the interference fringe pattern which is proportional to the speed of the fluid or body relative to the beams. The speed of a fluid in a pipe or a vehicle may be measured or as shown in Fig. 1 speed of a ship relative to the water. A blue-green light beam 1 from a laser is broadened by a telescope 2 and split into two beams by a double prism 3 which diverge on entering the sea through an aperture in the hull 12. A lens 6 brings each beam to a focus beyond the boundary layer of water surrounding the hull and light scattered back from each focus interfers in a dividing cube 4. The fringe pattern produced moves relative to the optic axis due to the Doppler shift which is opposite in each scattered beam and the rate of movement is measured by a phase retarding grating 7, or alternatively a diffraction grating, and a photomultiplier 10 coupled to a frequency meter. A quarter wave plate 5 and a polarizing filter (not shown) placed before the grating ensures that photo-multiplier only receives scattered light.

Abstract: 1,202,605. Stamping corrugations; jointing; making electric motors. MATSUSHITA ELECTRIC INDUSTRIAL CO. Ltd. 24 Nov., 1967 [8 Dec., 1966 (2); 22 Dec., 1966 (2); 20 March, 1967 (2); 19 April, 1967 (2)], No. 53659/67. Headings B3A, B3J and B3Q. Apparatus for bulge-forming comprises a tubular elastic insert having a corrugated outer contour corresponding to that required on a finished product and means for applying pressure to the inside of the insert to expand it within a tubular workpiece. The workpiece is expanded without constraint of an external die, but may be expanded against another, rigid workpiece. As applied to corrugating a seam-welded stainless-steel tube 6<SP>1</SP>, Fig. 9b, to form a corrugated product, Fig. 2b (not shown), the outer surface 1a of the polyurethane-rubber insert 1 is formed with corrugations. A flexible, inner high-nitrile rubber membrane 2 seals an annular chamber to which oil is supplied under pressure for expanding the workpiece. In another construction, Fig. 12b, the insert 1 has sealing lips 1b engaging counterbores in end plates 213 which are held together by bolts 4. In a similar construction, Fig. 14, a central band of corrugations of greater diameter is formed by reducing locally at if the wallthickness of the insert 1. The apparatus may be adapted in different ways for forming and securing the inner, seam-welded, stainless-steel liner 4, Fig. 16a, in a sealed electromotor stator. In one way, Fig. 18, first a central section of the liner is expanded against the core 2 by inflation of the tubular membrane 8, and then a second tool, Fig. 20, is used to corrugate the sections 4<SP>1</SP> and expand the ends into engagement with rings 5. A different second tool can be used, Fig. 21, or both operations can be formed simultaneously using the tool of Fig. 22.

Abstract: 1288421 Read only memory TEXAS INSTRUMENTS Inc 7 Nov 169 [30 Dec 1968] 54710/69 Heading G4A A read only memory comprises rows of conductive elements selectively coupled between row and column conductors such that the presence and absence of a coupled element first and second or second and first binary states respectively, the convention adapted for any given row being such that the row contains no more than a predetermined number, e.g. half the total number of bit positions, of coupled elements and being indicated by a tag. Each row where the total number of ones to be stored is greater than half the number of bit positions is complemented and a tag bit is added at the end of the row. The procedure is repeated for the columns, the tags being located at the foot of the column. The rows are then re-examined and the sequence repeated until the number of ones in any row or any column is not more than one half the number of bits in that row or column. The store which may comprise diodes selectively coupled between word and bit lines is then constructed in accordance with the data derived from the application of the above procedure. The tags are stored in an additional row and column. In the illustration the diode connections are shown as dots. The data is read out through a system of gates which reconstructs the original data. The exclusive-OR gates 41-46 are connected to the column outputs and to the tag bits stored in the lowest row. The data read from the columns is thus complemented if the associated tags are ones. The exclusive -OR gates 51-56 operate in a similar fashion, one input of each gate being connected to the tag column output.

Abstract: 1,115,434. Opening containers. ROGER BAJULAZ S.A. 3 Feb., 1966 [15 March, 1965], No. 54966/66. Heading B8D. [Also in Division B4] A device for opening a tetrahedron-shaped flexible container by cutting off a flattened apex thereof comprises two members 1, 2, the member 2 being slidable within the member 1 and each member having two perpendicular walls 3, 4 or 11, 12, joined by a curved wall 5, or 13, a slot 6 being formed in the wall 5 for receiving the apex of the container, an abutment 10 being provided in the wall 4 for positioning the apex, and cutting edges being formed respectively by one edge 7 of the slot 6 and by the leading edge 14 of the wall 13, the cutting edges being movable one towards the other transversely to the slot 6 and arranged relatively to the abutment 10 such that the line of cut is not straight and intersects an edge of the apex at an angle greater than 45 degrees on the apex side of the cut. Each member 1, 2 has flanges 8, 9, or 15, 16. The wall 12 has a groove 17. In operation, the user grips the flanges and slides the member 2 out of the member 1 until the abutment 10 comes into contact with the end of the groove 17. The apex is then inserted into the slot 6 until the sides forming the apex bear against the walls 3, 4. The member 2 is then moved back into the member 1 so that the cutting edges 7, 14 cut off the apex. Alternatively, the device comprises two members which are hinged to each other so as to act like pincers. The two members defining the cutting edges may be biased apart, e.g. by means of a spring. Each member may be made from one piece of metal. The developed shape of the slot may be conical.

Title: Bistable Circuit
IPC: H03K19/173
Filed: 1968-11-20
Abstract: 1,169,849. Computers. INTERNATIONAL BUSINESS MACHINES CORP. 20 Nov., 1968 [8 Dec., 1967], No. 54988/68. Heading G4A. [Also in Division H3] A gate circuit 25 receives the output of a bi-stable latch K1 and is inhibited from passing the output when the output is between predetermined levels. In a computer control register, Fig. 5, if a latch-setting signal, for example G1, should happed to be attenuated (G, Fig. 3, not shown), partial switching may occur and a temporarily unstable latch output be produced between high and low threshold levels (K, Figs. 3, 4, not shown). A high threshold detector H1 gives a true output when the latch output is above the high threshold, and a low threshold circuit detector L1 gives a true output when the latch output is above the low threshold, the L1 and inverted H1 outputs being compared in an AND gate 45 whose output is consequently true only when the lower threshold is exceeded and not the higher one. This output is inverted at 58, so that a line 62 carries a false signal to inhibit the output AND gate 25 from responding to the two other inputs it receives from the latch K1 via an OR gate 30, and from H1. The control register comprises a plurality of bi-stable latches K1 to K4, each receiving its setting signal from a corresponding AND gate 15, so that when an ENABLE signal occurs, any coincident information signals S1 to S4 (which are asynchronous) set their associated latches. An OR gate 30 operates, through an invertor 35, to prevent any further response to the S1 to S4 signals as soon as at least one latch is set, and thus a " batch " is set up, for feeding a priority logic system (not shown). Priority of operation of the output AND gates 25 is arranged by connecting the output of the inverter 48 associated with each high threshold circuit H1 to H4 to the AND gates 25 of any lower latches in the set. A delay 40, which inhibits all output AND gates 25 for a period until the bi-stable latches K1 to K4 are all resolved, is referred to as an undesirable alternative for dealing with possible partial switching in the latches, which is not now necessary with the arrangement of the invention; although it may be retained with a very short delay time.

Abstract: 1,186,359. Measuring the energy of electromagnetic radiation. A.J. SCHMIDT. Dec. 14, 1967 [Dec. 19, 1966], No.56608/66. Heading G1A. In a method and apparatus for measuring the energy of electromagnetic radiation, a hollow body, the walls of which are sufficiently opaque to the radiation and sufficiently non-reflective to cause substantially complete absorption, and which is thermally insulated, has the radiation beam directed into its interior and the resulting change of eletrical resistance of the body is measured as an indication of the absorbed energy. The body is of the tangled wire or "rats nest" type using enamelled copper for low powers or oxide coated aluminium for higher powers, and may be spherical with a small hole for the admission of radiation, formed by two cones base to base, of spirally wound wire, or by a single cone of wound wire. Two layers may be sufficient. The radiation may be directed into the hole by a lens the focal plane of which is at the hole, and the body may be suspended by nylon cords or supported in thermal insulation such as foamed polystyrene in a chamber which may be evacuated. The instrument or chamber may include two such hollow bodies which may be connected in different arms of a Wheatstone bridge to compensate for ambient conditions. The apparatus may be used for measuring the energy content of a laser beam and may be calibrated by comparing the resistance charge with that, arising from the passage of a known current. Wire winding and sphere forming arrangements are described.
