IPC: A47H15/00
Filed: 1923-12-12
Abstract: 227,264. Wilson, E. L., and Kingsley, E. D. Dec. 12, 1923. Curtains, drawing and suspending.-In curtain-suspending devices of the kind in which runners are drawn along tracks by means of cords attached to master runners, each master runner is connected to its operating-cord by a member adapted to pass freely between guide pulleys or other guides provided at bends in the track, and to adjust itself relatively to the master runner as it passes the guide pulleys &c. In the construction shown in Figs. 2 and 3, each master runner comprises two runners 1, of the type described in Specification 202,798, pivotally connected at their upper ends 2 to a bar 3 provided with a pivoted link 7 the free end 8 of which loosely embraces the cord 6 between the stops 11. A spacing bar 4, connected by a bar 5 to the bar 3 may be provided. At bends in the track 12, the cord 6 passes between grooved pulleys 14 spaced so that the link 7 passes between them with sufficient clearance to be able to pivot and adapt itself to the cord as it passes the pulleys. In the modification shown in Fig. 4, in which the operating-cords are disposed behind the track, the link 7 is flexibly connected, by a chain link 18, to an arm 19 pivoted to the bar 3 of the master runner, the guiding of the cord 6 at each bend being effected by a guide pulley 21 and curved guide plate 27. Specification 136,004 also is referred to.

Title: Process for the manufacture of a titanium dioxide pigment for delustering polyamide fibres
IPC: D01F6/60
Filed: 1966-07-14
Abstract: Delustred polyamide fibres are spun from a polyamide containing bitanium dioxide which has been treated with a water-soluble manganese salt and orthophosphoric acid and/or a water-soluble orthophosphate to render the TiO2 photo stable (see Division C1). The pigment so coated with manganous orthophosphate can be also coated with silica and hydrated metal, e.g. aluminium, oxide, or substantially water-insoluble compound.  In Example 3 the pigment is incorporated in nylon 6 fibres.ALSO:Titanium dioxide pigment is produced by treating titanium dioxide, maintained in suspension in an aqueous medium, with a water-soluble divalent manganese salt and orthophosphoric acid and/or a water-soluble orthophosphate. The mixture is neutralized if necessary and the treated pigment is separated, washed, dried and ground.  Additionally the pigment may be treated with a water-soluble metal, e.g. aluminium, salt and a water-soluble silicate, to produce on neutralization a substantially colourless and insoluble hydrated metal oxide or compound or silica. The preferred range of divalent manganese salt added is 0.05-2% Mn by weight with a most preferred range of 0.1-1.0% Mn.

Title: Method for separating the constituents of coal-pitch and the like
IPC: C10C1/00
Filed: 1955-11-09
Abstract: In a method of obtaining in a pure state the soluble constituents of a complete organic mixture, e.g. coal-tar pitch, petroleum pitch and asphalt, a series of solutions are prepared each of which contains a plurality of constituents, individual constituents being separated from the various solutions by chromatography, electrophoresis or fractional molecular sublimation.  The series of solutions may be obtained by treating the complete organic mixture with a number of solvents or a primary solution may be prepared, e.g. with pyridine as solvent, containing all or most of the soluble constituents and successive small quantities of a nonsolvent, e.g. water, are added to give a number of precipitates which are separately collected and re-dissolved to give the series of solutions.  In an example a pitch was treated with 30 parts of ether saturated with water and the solution was treated with 85 per cent alcohol precipitating half of the dissolved matter.  The remaining solution was chromatographed on alumina and then on silica using in each case acetone as the eluent. The third solution thereby obtained was treated with a mixture of aniline and cyclo-hexane and constituents corresponding to 1/10 th of the initial pitch collected in the aniline layer.  This solution was chromatographed on alumina and each of the fractions successively collected was treated on silica using as eluents ether, cyclo-hexane, acetone, alcohol and pyridine.  Among the many compounds finally obtained were chrysene, fluorene, trioxynaphthalenes, ortho- and meta-hydroxybenzoic acid, xanthene and picolinic acid.
