Title: Reinforced carded webs
IPC: D04H1/66
Filed: 1936-03-10
Abstract: 468,529. Agglutinated fibrous sheets; compound sheet materials; coating webs. GOLDMAN, J. H. March 10, 1936, No. 7209. Convention date, March 15, 1935. [Class 140] [Also in Group IX] A web of carded fibres is strengthened by bonding substantially all the fibres together by impregnation with a binder applied locally into the body of the web, the area of the web occupied by the binder being only a small fraction of the total area of the web. The binder may be applied in narrow lines running transversely of the fibre direction, or both transversely and longitudinally, and spaced apart at distances not exceeding the average fibre length. A number of treated webs may be superposed, or a multiple web wherein the fibres in adjacent plies cross at an angle may be impregnated along criss-cross lines. As shown, a carded web unwound from a roll 15 is passed between a resilient, e.g. rubber-faced roll 16 and a roll 18 having raised binderapplying portions which receive the binder from a roll 19, is passed over drying drums 21, and wound up. The raised binder-applying portions may be cupped or recessed to minimize spreading of the binder. The binder, which may be applied in viscous or concentrated condition, may comprise rubber solution or latex, viscose, cellulose ester, e.g. cellulose acetate in solution, resin solutions, e.g. phenolformaldehyde or vinyl resin, gums, waxes, starch, glue, or gum arabic. Cotton fibres, freed from natural waxes, resins, and oils as by boiling with alkali, may be used, or sisal, flax, hemp, jute, or silk. The product is used for surgical dressings and bandages, filter media, or padding for pillows, mattresses, and furniture. The Specification as open to inspection under Sect. 91 comprises also the impregnation with criss-cross lines of binder of webs in which the fibres are arranged promiscuously, entangled, or felted, e.g. airlaid or waterlaid webs. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,180,821. Fibrous articles. D. F. EDNELL. 15 Feb., 1967 [13 April, 1966], No. 7242/67. Heading B5A. Articles of fibre material are produced by immersing a permeable mould or former in a fibre slurry for a period of time under pressure, thereby forcing the liquid through the mould and depositing the fibres on the mould, the slurry then being removed from inside the mould and further dewatering is effected by the introduction of gas under pressure. As shown in Fig. 1, the apparatus comprises a mould 1 placed in a container 2 divided into two parts 2a, 2b connected by funnel-shaped aperture 3a, the container having a lid 5, there being a reservoir 6 from which to supply slurry to the container via pipe 8 controlled by valves 15, 4. Slurry is supplied to container section 2b to fill it, valve 4 is closed and gas is supplied at 13 to force the slurry into section 2a and through the mould 1 depositing the fibres thereon, liquid being removed at 16. Further dewatering is effected by introduction of pressure medium via pipe 19. After sufficient time, valve 4 is opened, excess slurry being run off through branch pipe 7. The mould has flanges 1a, 1b to enable straight-edged articles to be produced. The article may be removed with the mould from the container and rolled to enable the sleeve produced to be enlarged to a greater diameter and thereby removed from the mould.

Title: Process for the production of gases containing methane from hydrocarbons
Inventor: DENT FREDERICK JAMES
IPC: C01B3/38
Filed: 1958-03-06
Abstract: A methane-containing gas is produced by reacting a mixture of hydrocarbons containing predominantly paraffinic hydrocarbons with an average carbon content of 4-10 carbon atoms in the vapour phase with steam over a bed of nickel catalyst at atmospheric or superatmospheric pressure, the reactants being heated to a temperature of above 350 DEG  C. and such that the bed is maintained at 400-550 DEG  C.; two reactions take place the first endothermically producing carbon monoxide and hydrogen which react exothermically to give methane, the latter reaction providing at least part of the reaction heat of the former.  Pressures up to 50 atmospheres may be used and the amount of steam added may be 1.5-5 parts by weight per part of hydrocarbon.  The catalyst may contain 15% of reduced nickel on alumina.  The product may be enriched in methane, after removal of carbon dioxide and water, by reacting carbon monoxide and hydrogen present at 400 DEG  C. or lower over a nickel catalyst.  Alternatively, the methane content may be decreased by reacting with steam over a nickel catalyst at above 550 DEG  C., air or oxygen being introduced to provide the necessary reaction heat by combustion.

IPC: F23J1/00
Filed: 1921-03-07
Abstract: 184,211. Withers, J. S., (Deutsche Evaporator Akt.-Ges.). March 7, 1921. Air, heating and supplying; grates; ash-pits.-The fuel residues from furnaces are fed on to a secondary grate where they are consumed and utilized for heating air, which is afterwards supplied beneath the main grate. Fig. 1 shows a furnace having a travelling grate 1 from which the fuel residues are discharged on to a secondary grate 2. Air to support combustion of the fuel on the main grate is passed up through the secondary grate, where it effects the combustion of and is heated by the fuel residues and is then led through passages 4, 22 in the side walls of the furnace and issues through openings 23 in the side walls of the ash-tray 4'. A fixed or movable wall 8 prevents air from passing from the grate 2 direct to the furnace above the main grate. Cold air may be led through a channel 6 direct to the passages 22. In the modification shown in Fig. 4, the secondary grate is arranged beneath an inclined grate provided at the rear with an auxiliary ash-dumping grate and may be rotated, oscillated, or reciprocated. It comprises a tray 9 mounted on pivots, one of which is hollow and serves for the introduction of compressed air beneath the inclined fire-bars 10. The secondary grate is oscillated by a bar 13, and ashes are discharged through lateral pivoted sluices 14. Air is sup. plied to the secondary grate through the conduit 15<1>, which is provided with a branch 17<1> leading to adjustable louvers 16 which regulate the supply of air direct to the main grate. The auxiliary grate 19 comprises front and rear members mounted on pivots 29 which rest in bearings 32, 33. The bearing 32 is fixed on a support 34 and the bearing 33 may be displaced by a rod 20 to regulate the passage for the fuel residues. The members of the auxiliary gate are rocked by a rod 24, link 31, bell-crank 38 and links 30.

Abstract: A solution obtained by mixing viscose with rubber latex in the proportion of 10 per cent of viscose calculated on the dry rubber content of a 40 per cent solution of latex is extruded and coagulated with formation of threads which may then be vulcanized. The rubber latex and viscose may be mixed in a container adjacent the spinneret.ALSO:A solution obtained by mixing viscose with rubber latex in the proportion of 10 per cent of viscose calculated on the dry rubber content of a 40 per cent solution of latex is extruded through a spinneret into a coagulating bath, and the threads obtained may be vulcanized.  The addition of viscose results in a yarn of lower extensibility than a similar yarn of rubber only.  The yarn shows less tendency to crinkle when removed from a machine which wraps it round with cotton or other material than is the case with a yarn made from rubber only.  The rubber latex may be mixed with the viscose in a container adjacent the spinneret.
