Title: A condensed filamentous mat and method for making same
IPC: D04H3/07
Filed: 1960-06-10
Abstract: 911,157. Fabrics of adhesive-bonded threads; wadding. AMERICAN AIR FILTER CO. Inc. June 10, 1960 [June 25, 1959], No. 20449/60. Classes 42 (2) and 140. [Also in Groups IX and XXIII] A filamentous mat is composed of a plurality of monofilaments which are arranged in overlying layers, the monofilaments of one layer being arranged in groups in crossed relationship with the mono-filaments of adjacent layers, each group comprising at least one border of relatively closely-spaced monofilaments forming a flat ribbon and a plurality of relatively widely-spaced monofilaments adjacent said border. The mat may be made by traversing a filament feeder axially back and forth along a drum and rotating the drum a multiplicity of times during each traverse of the feeder, gathering a portion of the filaments in a zone intermediate said feeder and said drum into one or more substantially planar concentrated groups of individual and separate filaments lying closely together relative to the spacing of said filaments as discharged from said feeder, feeding said gathered portion of closely spaced filaments on to said drum in relatively closely spaced ribbon-like forms and simultaneously feeding the remaining portion of the filaments directly from said feeder on to said drum adjacent said closely spaced filaments in relatively widely spaced form approximately equalling the spacing between individual filaments discharged from said feeder. As shown in Figs. 1 and 2, glass filaments 17 are discharged through spinnerets in orifice plate 16 of glass furnace 10 which is mounted in rails 14 and adapted to be driven with a reciprocating movement as indicated by the double-headed arrow in Fig. 1. As the furnace assembly is reciprocated, drum 2, mounted on supports 4 and 6 and driven by belt 8 is rotated a multiplicity of times during each traverse of the furnace. A central and minor portion of filaments 17 is fed directly on to drum 2 while the axially outer filament portions are collated into two substantially planar or ribbon-like filament groups 41 by opposed spools 18, which groups are also simultaneously fed on to the rotating drum. As the furnace traverses, the filaments are laid in helical turns having an angular disposition first in one direction and then in the opposite direction. Binder is sprayed from applicator 66 as the filaments are being spun onto the drum. The cylindrical mat formed on the drum is slit axially and removed from the drum, thus constituting a planar condensed mat 68 (Fig. 8). Mat 68 is stretched axially to form an elongate expanded web having a thickness appreciably greater than the desired final thickness. The expanded web is carried by conveyer 71 through an oven 72 to cure and harden the binder. Pressureplate 74 compresses the expanded web to the desired thickness and the web is subsequently cut to desired width by slitting apparatus 76 and cut to desired length by cutter 78. Specification 891,715 is referred to.

Patent GB-479441-A (GB)
Title: An improved process and apparatus for purifying crude hydrocarbons
IPC: C10G29/20
Filed: 1936-08-04
Abstract: <PICT:0479441/III/1> The process of purifying crude hydrocarbons described in the parent Specification, which comprises passing the hydrocarbons in vapour form through carbolic acid or homologues thereof, is modified in that the purifying agent is applied to a porous body such as bleaching earth, infusorial earth, pumice, charcoal, coke, silica gel, kieselguhr, or activated charcoal.  The purifying agent may be applied to the porous body in any way, e.g. by dipping or spraying, and may be diluted with a light oil, e.g. benzine or benzole to assist uniform application.  The crude hydrocarbon may (a) be distilled and the successive fractions passed through the purifying agent, or (b) be heated under pressure and expanded by release of the pressure, so that it is vaporized as a whole, and the resulting vapour passed through the purifying agent. The mean boiling temperature of the hydrocarbon may be lowered by adding low boiling constituents or carrier gases, e.g. inert gases, methane, propane, or butane.  An apparatus for carrying out the second process comprises a container t for the hydrocarbon to be purified, e.g. crude benzene or benzole or crack benzene, connected by a pump p to a heater e communicating through a reducing valve v with a purifying vessel r containing porous bodies a impregnated with the purifying agent and, if desired, porous bodies c unimpregnated with purifying agent; the vessel r may be provided with heating means h, and is connected to a condenser k.  In examples: (1) crack benzene is fractionally distilled and the vapours passed through kieselguhr impregnated with cresol; (2) crude benzole is distilled, the fraction boiling below 120 DEG  C. being passed through liquid carbolic acid, and the higher boiling fractions together with methane as a carrier gas, passed through xylenol applied to coke; and (3) benzene or benzole is led under pressure through a heater, the pressure reduced, and the resulting vapour passed respectively through bleaching earth or wood charcoal impregnated with cresol.
