Title: Improvements in or relating to the preparation of sulfur oxyfluorides
IPC: C01B17/46
Filed: 1956-04-05
Abstract: Sulphuryl fluoride and/or thionyl fluoride are prepared by pyrolyzing a sulphur oxyfluoride, containing two fluorine atoms and hexavalent sulphur, and of higher molecular weight than the desired end product, e.g. pyrosulphuryl fluoride or sulphuryl fluoride, at between 200 DEG and 1800 DEG  C.  The pyrosulphuryl fluoride may be prepared by reacting metal fluoride and sulphur trioxide under pressure at below the decomposition temperature of pyrosulphuryl fluoride.  At 200-700 DEG  C. the main product of pyrolysis is sulphuryl fluoride, but at 700 DEG  C. and above, thionyl fluoride is formed by pyrolysis of sulphuryl fluoride.  The apparatus should be of inert metal, e.g. steel, stainless steel or iron at 200-500 DEG  C., nickel, nickel alloy, or platinum at 500-700 DEG  C., and platinum at above 700 DEG C.  To increase the conversion and to increase the proportion of thionyl fluoride at higher temperatures, sulphur, carbon monoxide, carbon disulphide, or iron sulphide with an S : Fe atomic ration > 1 may be present; sulphur is effective at 400 DEG  C. and above and carbon monoxide and disulphide at 500 DEG  C. and above.  The oxyfluorides may be separated by fractional distillation and may be used in the synthesis of fluorocarbon compounds.  In the examples the reaction is carried out in a nickel base alloy bomb tube and the oxyfluoride product distilled therefrom, or nitrogen is bubbled through pyrosulphuryl fluoride to form a gas mixture, which is passed through a platinum tube with, or without, calcium fluoride pellet packing, or a nickel tube containing FeS1.2, and the oxyfluoride product is condensed out of the issuing gases in a trap cooled in liquid nitrogen.  Specifications 760,657 and 766,326, [both in Group IV (b)], are referred to.ALSO:Carbon tetrafluoride, a mixture of CF4, C2F4 and C2F6 and difluoro-diphenyl methane respectively are obtained as follows from sulphuryl or thionyl fluoride, prepared in specified manner (see Group III): (a) sulphuryl fluoride diluted with N2 is passed through a tube, lined with nickel-iron-molybdenum alloy, and charged with carbon at 1000 DEG  C. to form CF4, which is condensed in a receiver; (b) thionyl fluoride is passed through a carbon arc and converted to C2F4, CF4, and C2F6, in molar ratio 3 : 5 : 2; (c) a mixture of benzophenone and thionyl fluoride is heated at 300 DEG  C. to form difluorodiphenylmethane. Specifications 760,657 and 766,326 are referred to.

Filed: 1936-04-09
Abstract: 473,300. Embossed tissue paper. BURGESS, A. F. (International Cellucotton Products Co.) April 9, 1936, No. 10504. [Class 96] [Also in Group XVI] A paper article soft enough to be suitable for use on the face consists of a crÛped tissue paper sheet on which is formed an all-over pattern by embossing accompanied by stretching, the pattern being not materially coarser than the crÛpeing and comprising a multiplicity of elements separated by interposed areas of sheet which remain in their initial condition. A web of tissue paper is dried on a drying roller and removed by a doctor blade which crÛpes it transversely. Two rolls 15 of this crÛped tissue are unwound and the superposed tissues passed between pairs of calendar rolls 16 which crush some of the striations of the crÛpeing and effect a stretching of the multiple web, which is then fed between a hard embossing roll 17 and a platen roll 18 with a soft resilient covering 19. A suitable pattern shown in Fig. 7 consists of a multiplicity of small, rounded, oblong projections, spaced from each other a distance less than their width. There may e.g. be 30 lines of embossing/inch in one direction and 24/inch in the other. Preferably the pattern interrupts all the lines 14 of the crepeing. Since the sheets are gripped during embossing over a wide zone the embossing is accompanied by stretching of the sheet material.

Title: Improvements in screw cutting lathes
Inventor: LUCIE ALBERT
IPC: B23G3/04
Filed: 1965-03-15
Abstract: 1,114,771. Screw-cutting lathes. WICKMAN LANG Ltd. 14 March, 1966 [15 March, 1965], No. 10831/65. Headings B3B and B3T. In a screw-cutting lathe, the lead screw 17 for feeding the tool saddle, Fig. 1, is connected for rotation with the work spindle 10, and if a screw-thread is to be produced in which the ratio of the threads to be cut is not an exact multiple of the threads per inch of the lead screw, the latter is moved axially by means actuated by the movement of the saddle. Spindle 10 is driven by a motor through gearing, and lead screw 17 is driven through gearing 13, 13a, 14, 14a, and a sleeve 15 splined to the end 16 of the lead screw. The latter is carried in a bearing 18, slidable in guides 19, 20, Fig. 2. A slide 25 slides in a vertical slot 24 in the bearing and supports a roller 26 which travels in a channel 27a formed in a member 27 which is adjustable about a pivot 28. Pivot 28 is angularly adjusted by a micrometer screw and nut 31, 32, Figs. 1 and 2, the amount of adjustment being indicated on a linear scale 38. A rack 39 on slide 25, meshes with an elongated pinion 40 which is rotated by a worm and wheel 49, 50, the worm carrying a sprocket 47 which is connected to a second sprocket 46, Fig. 4, by a chain 45 connected at its ends to the tool saddle 43. In operation, gears 14, 14a are set so as to provide a simple gear ratio, when the ratio of the screw-threads is exact. Member 27 is adjusted so as to lie at right angles to the axis of lead screw 17. A half nut in the saddle is moved into engagement with the lead screw and the saddle is traversed by the rotation of the lead screw. As the saddle moves, chain 45 rotates sprocket 47, worm and wheel 49, 50 and pinion 40, so that slide 25 is moved vertically, and roller 26 moves freely in channel 27a. When cutting a thread with a ratio that is not exact, gears 14, 14a are set to the nearest approximation of the ratio, and member 27 is pivoted by screw 33, until the scale 38 indicates the necessary correction. When the saddle moves, slide 25 moves vertically, and roller 26 moves along the now inclined channel 27a and the lead screw is moved axially. The travel of the saddle is now due to the rotation, and also to the axial movement of the lead screw.

Abstract: 865,082. Nuclear fusion reactors; discharge apparatus. UNITED STATES ATOMIC ENERGY COMMISSION. April 1, 1959 [April 22, 1958], No. 10990/59. Classes 39(1) and 39(4). Apparatus for increasing the energy of charged particles comprises an evacuated chamber, means for establishing within the chamber an axially symmetrical radially inhomogeneous magnetic field having axially spaced reflector field regions, means for increasing the intensity of the field, and means for producing a ring of charged particles coaxially of the magnetic field and at a median plane between the reflector field regions so that the energy of the charged particles is increased in spiraling inwardly to the central axial region of the field. In the apparatus shown in Fig. 5 comprises a pair of coils 29, 31 and a plasma source 52 arranged within an evacuated container. The coils are connected in series through a switch to a charged condenser; when the condenser is allowed to discharge through the coils to produce a sinusoidal current through them, the magnetic field is initially inhomogeneous and heats the plasma non- adiabatically, and subsequently becomes homogeneous and compresses and heats the plasma adiabatically. The coils may be provided with pole-pieces (Fig. 6, not shown) to increase the initial inhomogeneity of the field. The plasma source, Fig. 7, may comprise a number of titanium rings 56 attached to an insulating member 53 and connected to a resistance chain (not shown). The titanium rings are loaded with deuterium or tritium which is evolved from the rings when an arc is established between them. Diametrically opposed rings 62, 63 are connected to an external charged delay line (not shown) and trigger electrodes 59, 61 are provided on either side of the ring 62. When the trigger electrodes are energized an arc is struck between them and ring 62, which evolves gas, and arcs are struck successively between the rings on either side of ring 62 and maintained until the delay line is discharged. In a modification of the apparatus shown in Fig. 5 two further coils are arranged inside coils 29, 31 and are arranged to compress the plasma adiabatically after its initial heating and compression by coils 29, 31 (Fig. 9, not shown). In another modification (Fig. 10, not shown) a further magnetic compression chamber is connected axially to the apparatus of Fig. 5 and plasma is transferred to it by short-circuiting coil 31.
