Title: Methods and Apparatus for Producing Steel Channel Sections.
Inventor: NODA IKUYA
IPC: B21B1/08
Filed: 1967-06-21
Abstract: 1,187,059. Rolling flanged bars. FUJI IRON & STEEL CO. Ltd. 21 June, 1967 [21 June, 1966], No. 28567/67. Heading B3M. An apparatus for rolling steel channel sections comprises a reversible roughing mill group composed of at least a universal rolling mill 13 and an edging mill 14. It is preferable to have a second universal mill 13<SP>1</SP> after the edging mill and to position the mills close together for continuous rolling. The ingots are shaped in a blooming mill (11), Fig. 4 (not shown), and delivered to the roughening mill for a series of forward and return passes. After the rough rolling the channel sections are finished in a finishing mill (15) which may be a universal mill or a structural rolling mill with grooved rolls. A pair of roughening mills (A), (A<SP>1</SP>) may be arranged in the pass line, Fig. 4b (not shown), each comprising a universal mill (13), (13<SP>1</SP>) and an edging mill (14), (14<SP>1</SP>). The universal mills have vertical rolls 22a, 22b and horizontal rolls 21a, 21b. The horizontal rolls are driven by a motor and the vertical rolls are driven by frictional contact with the work. Various shapes of rolls for the universal mill of the roughing mill are shown. The web of the channel is rolled between the horizontal rolls 21a, 21b and the flanges between the lower horizontal roll 21b and the vertical rolls 22a, 22b. The corners 41 formed in the universal mill are rounded off in the edging mill by driven horizontal rolls 23a, 23b or similar rolls in the other embodiments. The rolls 23a, 23b have outwardly angled surfaces and a recess so that they do not roll the centre of the web. The channel section may have various shapes, Fig. 3 (not shown), and may be W-shaped so that by cutting along the centre of the web angle sections with unequal leg lengths are formed, Fig. 3i (not shown). This section also prevents friction between the rolls and the flanges which are divergent but at right angles to the web. The finishing strands may be universal mills, Fig. 9 (not shown), or a structural rolling mill, Fig. 10b (not shown), with a series of passes through which the work is passed in turn. The flanges may be grooved by having grooved vertical rolls (62b), Fig. 11 (not shown), in the universal mill of the finishing strand. These vertical rolls may alternatively have other shapes to impress on the flanges.

Abstract: 982,444. Curtain heading tapes. M. DHIRY. July 19, 1963 [July 20, 1962], No. 28688/63. Heading A4B. [Also in Division D1] A curtain-heading tape 1 secured to the top of a curtain 6 has spaced longitudinal rows 2, 3, 4 of loops 5 formed by selected weft threads left unwoven by warp threads, corresponding loops in the rows being approximated by engagement by a spiral wire 12 to form a pleat in the curtain. The blunt end 13 of the wire 12 is inserted in selected loops of the row 4 and advanced by rotation by the handle 14 for engagement in selected loops in suceeding rows. A resilient suspensory hook 15 is inserted in, and engages, the wire 12 for hanging the curtain from a wire &c. By varying the number and position of the loops in each row which are engaged by the wire 12 the form of pleat is variable. In modifications the loops in each row are approximated by flexible wires, nylon threads or by clips, which may be common to more than one row. So that the loops stand up for easy threading the corresponding warp threads are of a colour and texture different to that of the other warp threads of the tape.

Title: Apparatus for the steering properties of endles-tracked vehicles
IPC: B62D11/18
Filed: 1976-07-09
Abstract: In order to enable full-track vehicles to travel around bends, the speed of the track on the inside of the bend is slowed down and that of the track on the outside of the bend is increased with the aid of a steering drive which is superordinate to the travel drive. However, in this way, with the given configuration of the steering drive transmission (9) it is no longer possible to go below certain bend radii. However, in order to obtain even smaller bend radii, according to the invention with complete or virtually complete activation of the steering drive the track on the inside of the bend is additionally decelerated. This is achieved in each case by means of a brake (17, 17') on each track drive wheel (5, 5'). At the latest with full lock of the steering element (12), the brake assigned to the respective inside of the bend is actuated. <IMAGE>

Title: Improvements in spinning artificial silk
IPC: D01F2/06
Filed: 1927-10-28
Abstract: 279,888. I. G. Farbenindustrie Akt.- Ges. Oct. 30, 1926, [Convention date]. Grant of Patent opposed. Apparatus for making filaments; cellulose xanthates, processes for making filaments from.- When spinning viscose silk, according to the bobbin system, the thread is projected upwardly in a substantially vertical direction, an upper bath is not used, and the thread in its passage to the collecting bobbin is either not bent at all or at most through an angle of 150‹. Spinning speeds lower than the normal are advantageously employed. All the above features are directed to reducing the strain to which the partly-coagulated thread is subjected, and they serve to give a product of uniform dyeing properties and of an extensibility of 18 per cent or higher. The method may be employed when spinning viscoses of high viscosity and low cellulose content, such as unripened viscose or viscose prepared from unripened alkali cellulose; and it may be used for the spinning of fine filaments, that is, below 3 deniers, good results being obtained with a sulphuric acid bath and a length of immersion which may be reduced to less than 60 centimetres to a few centimetres. The Specification as open to inspection under Sect. 91 (3) (a) refers to an arrangement comprising an upwardly-projecting nozzle g, Fig. 3 (Cancelled), a reciprocating thread guide c, and bobbins f arranged vertically above the spinning bath; and it refers to constructions of the guide c, which is provided with rear limbs a, a<1>, Figs. 1 and 2 (Cancelled), and free limbs b, b<1>, the gap between the rear and free limbs being of such a width that the thread rubs against them, the limbs b, b<1> being either bent down as shown in Fig. 1 (Cancelled) or bent upwardly and provided at the points b<2>, Fig. 2 (Cancelled) with projections so as to allow acid stripped from the thread to flow away.

Patent GB-797276-A (GB)
Title: Process for the production of artificial resins from compounds containing oxacyclobutane rings
Inventor: KOEHLER RUDOLF
IPC: C08G65/18
Filed: 1954-10-07
Abstract: Artificial resins are prepared by treating 3-methylol - 3 - chlormethyl - oxacyclobutane with not more than 10 per cent of a FriedelCrafts catalyst, preferably while heating and converting the resulting polyether to a polyoxacyclobutane by treatment with alcoholic alkali.  If desired the starting material may be mixed with not more than twice its amount of a mono- or di-oxacyclobutane which contains no carboxylic acid ester group in its molecule.  Suitable compounds for admixture with the 3-methylol-3-chlormethyl-oxacyclobutane may be prepared by splitting off hydrogen halide from 1,3-halohydrins, e.g. pentaerythritol dichlorhydrin, or by the process of Specification 729,459, [Group IV (b)].  Friedel-Crafts catalysts mentioned are boron trifluoride, aluminium chloride, ferric chloride, zinc chloride, and stannic chloride.  The polyoxacyclobutane compounds of the invention may be further polymerized by treatment with Friedel-Crafts catalysts preferably with heating.  In the examples: (1) describes the preparation of 3-methylol - 3 - chlormethyl oxacyclobutane, together with dioxaspiroheptane 3-methylol-3-ethoxymethyloxacyclobutane and a viscous yellowish residue by heating pentaerythritol dichlorhydrin with alcoholic caustic potash.  In Example 3, 3-methylol-3-chloromethyloxacyclobutane, similarly prepared, is heated with ethereal boron trifluoride to yield a product with the probable constitution: <FORM:0797276/IV (a)/1> In Example 3 a mixed polyether is formed by polymerizing a mixture of 3-methylol-3-chlormethyl-oxacyclobutane and 3-methylol-3-ethoxymethyl-oxacyclobutane in dioxane solution with boron trifluoride.  In Example 4, the product of Example 3 is refluxed with alcoholic caustic potash to yield a polyoxacyclobutane resin of molecular weight 1500, 3-3.5 per cent epoxide oxygen and 2.5-3 per cent chlorine.  This polyoxacyclobutane compound dissolved in dioxane and mixed with 3-methylol-3-chlormethyl-oxacyclobutane or 3-methylol-3-ethoxymethyl oxacyclobutane, was further polymerized with boron trifluoride.  If the solvent is omitted products of still higher molecular weight may be obtained with cooling to avoid initial local overheating.  In Example 5, the polyether of Example 2 is treated with alcoholic caustic potash to yield a polyether containing oxacyclobutane rings, which can be copolymerized with 3 - methylol - 3 - chloromethyl - oxacyclobutane or the corresponding ethoxymethyl compound.  Reference has been directed by the Comptroller to Specification 723,777.

Title: An improved process and apparatus for coating or impregnating webs
IPC: D06M23/04
Filed: 1948-11-08
Abstract: <PICT:0667277/IV (c)/1> <PICT:0667277/IV (c)/2> Liquid is applied to a web by conducting the web above a supply of liquid but through a mass of bubbles formed on the surface thereof which burst and deposit liquid on the web.  The web may be of paper, metal, wood, plastic, or woven, knitted or netted fibres and the applied liquid may be a dye. A web 8, Fig. 1, of loose unspun fibrous material is taken from a reel 6 and attenuated between two pairs of drafting rollers 11, 12 and 14, 15, being supported therebetween by an endless belt 10.  The web is passed over a trough of liquid 22, which is maintained at a constant level, and through a mass of bubbles 38 formed on the surface thereon by passing a stream of gas, e.g. air upwardly through the liquid from a pipe 26.  The web then passes between a pair of cylinders 18 and 19 one or both of which may be heated.  A water jacket 30 may be provided to prevent the heat from the cylinder 18 being conducted to the liquid 22.  The web is wound up at 20. Pressure and a doctoring action may be applied to the web as it passes over cylinder 18 by a number of steel balls 50, maintained within a frame 40 supported above the web.  These balls also exert a doctoring action upon both of the cylinders 18 and 19.  The cylinder 18 may be rotated so that its peripheral speed exceeds that of the web so that the impregnated web will not adhere to its surface.  The speed of the web is determined by drafting rollers 14, 15, the lower of which, 15, is power-driven and the upper of which, 14, is geared thereto and rests upon the web under its own weight.  The rollers 11 and 12 are similarly operated.  In a modified arrangement, Fig. 11, a single cylinder 18 is employed in cooperation with a heating shoe 60 between which and the cylinder the web passes.  To ensure stripping of the web from the cylinder the latter is driven from 1 to 5 per cent faster.

Abstract: 1400361 Measuring length photo-electrically E I DU PONT DE NEMOURS & CO 19 June 1973 [20 June 1972] 28991/73 Heading G1A The length of a staple fibre is determined by projecting a staple fibre without substantial residual crimp past a series of spaced detectors for detecting the presence of the fibre, determining the velocity of the fibre by dividing the distance between two detectors by the time it takes one end of the fibre to pass from the first detector to the second detector, determining either the time taken for the two ends of the detector to pass one of the detectors and multiplying this time and the velocity value to give an indication of the length, or the time period between the leading edge of the fibre passing a third detector spaced a distance Lo from the second detector and the trailing edge passing the second detector and summing the distance Lo and the product of the velocity value and the time period. As shown, the fibres are sucked down a passageway 50 by means of a suction device 40, the passageway being defined by transparent plates 12, 14, 16, 18 mounted between two blocks 20, 30. Only one detector is shown in Fig. 2, this consisting of a light source 66 which projects light into the edge of plate 12, and a photo-cell 62 mounted above the plate 18. However, two or more detectors are provided along the passageway as shown in Fig. 3. In the simplest embodiment only two detectors are utilized. However, a third detector E or E<SP>1</SP> may be used, this detector being selected, by a switching arrangement, from a number of further detectors. Circuitry for processing the pulse outputs of the detectors is described with reference to Fig. 2 (not shown). A read-out of the fibre length may be provided as the values of the time periods may be displayed so that the length can be determined manually.
