Title: A process for adjusting the dyeability of tows of acrylic fibres or filaments
IPC: D01F6/18
Filed: 1966-06-20
Abstract: 1,132,487. Adjusting dyeability of acrylic fibres. E. I. DU PONT DE NEMOURS & CO. 20 June, 1966 [21 June, 1965], No. 27470/66. Heading B5B. [Also in Division D1] The dyeability of a tow of acrylic filaments which may have been formed by dry spinning a solution of the polymer in a water-soluble volatile organic solvent such as dimethyl formamide is adjusted to be within a predetermined range by passing the tow through a washdraw zone in which it is simultaneously drawn and washed with an aqueous solution maintained at an elevated temperature and the drawn tow is then dried and its dyeability is determined and compared with a standardized range of dye receptivity for the fibres being produced. If the dyeability of the tow product being produced is found to be outside the standardized range of dye receptivity, the dyeability of further tow product being produced is brought within the specified standardized range by changing the wash liquid temperature to a value (as determined from a previously established empirical relationship between wash-water temperature and product dyeability) at which the dyeability of the further tow product is brought to a level within the specified range. In general, an increase in wash water temperature results in a decrease in dyeability and it has been found that the lowest dependence of dye receptivity on wash water temperature occurs in the range of 94 to 96 C. The acrylic filaments may be drawn to 150 to 600% of their as-spun length in a bath consisting of a solution of the spinning solvent in water at a temperature normally maintained at a value within the range of 90 to 100 C. passed counter-current to the passage of the fibres, whereby the solvent content of the fibres is reduced to 1À5% or less. Acrylic fibres are defined as fibres comprising at least 85% acrylonitrile and 0 to 15% of a polymer of at least one other ethylenically unsaturated monomer, e.g. 93À8% acrylonitrile, 6% methyl acrylate and 0À2% sodium styrene sulphonate.

Abstract: 859,225. Overhead conveyers. KING Ltd., G. W. Aug. 7, 1959 [Aug. 27, 1958], No. 27482/58. Class 104 (2). In a conveyer system comprising a roller track and an endless chain having depending dogs to propel the load carriers along the roller track, the load is stopped and the depending dogs are moved out of driving engagement therewith at a selected holding station and the load carrier, on stopping, effects stoppage of the next following load carrier at a preselected distance therefrom. In the arrangement shown in Figs. 1 and 2, C-shaped load carriers 13, provided with shoes 14 adapted to move over freely rotatable rollers 12, are propelled by vertically movable dogs 22 depending from an endless chain 18 supported by trolleys 20 mounted on a track 21. A shoe 14, on movement of a load carrier along the roller track, engages a roller 36 to pivot a lever 34 and hence links 25, 26 through a rod 33 in order to move a ramp 24 upwards into the path of rollers 23 projecting from the sides of the dogs 22. The rollers 23 now engage the ramp 24 and lift the dogs 22 out of engagement with a load carrier shoe 14. The forward end of the ramp 24 engages an extension 38 to pivot and hold a stop member 37 in the operative position blocking the forward movement of shoe 14. This shoe 14, in the stationary position, pivots and holds a lever 34<SP>1</SP> in the pivoted position to move a ramp at a preceding station (Fig. 1a, not shown) into an operative position to stop a load carrier thereat. The ramp 24, once the forward shoe 14 disengages the lever 36, is held in the operative position by a locking member 29, biased to the operative position by a spring 30, Fig. 2, and engaging link 25. To release the stationary load carrier a solenoid 32 is energized to pivot the locking member 29 to the inoperative position, thus allowing the ramp 24 to drop, the stop 37 to pivot to the inoperative position and dogs 22 to engage the shoe 14 of the stationary load carrier. The shoe 14, on being moved, disengages the lever 34<SP>1</SP> to permit the load carrier at the preceding station to be moved. Specifications 701,610 and 763,943 are referred to.

Optical means combined with or adapted to be fitted to a kinematograph or photographic camera having a single lens for use in the production of a stereoscopic pair of pictures comprises light deviating means, e.g. prisms or mirrors, disposed or adapted to be disposed sufficiently far in advance of the camera lens to prevent image overlap and a mask disposed in the film gate of the camera or near the light deviating means for obscuring one half of each film frame. As shown in Fig. 5, the light deviating means comprises two internally reflecting prisms 3, 4 of which prism 3 has one edge in a vertical plane passing through the optical axis of the camera lens 1. Prism 4 may be adjustable and is so arranged that the angle between the reflecting faces of the prisms is equal to one quarter of the angle of field of the lens 1 so that corresponding rays such as 5 and 6 emanate from a common object point. The prisms are so positioned that the rays reflected form the right-eye image r of a stereoscopic pair on a film 2, which image does not overlap the left-eye image l forms by rays received by the camera lens direct from the object. A mask which extends downwardly from the lens axis and covers half the field of the lens is provided so that the images land r each occupy one quarter of a normal film frame. The mask may alternatively be positioned so as to cover the vertical half of the lens field whereby the images l and r are justaposed one above the other on the film. The unexposed parts of the film may be exposed by running the film through the camera a second time and arranging the mask so as to cover the already exposed parts of the film. The optical means may be embodied in an attachment comprising a body portion and a base 19, a bracket 23 on which has an aperture for receiving a plug 24 which threads into one of the objective receiving apertures of the lens turret 22 of a camera 21. One of the lenses in the turret registers with an aperture 20 in the rear of the body portion of the attachment. An aperture 26 is provided in a re-entrant part of the body portion, the inner edge of this aperture being aligned with a line bisecting the aperture 20 in a vertical direction and the upper edge of the aperture 26 being aligned with a line bisecting the aperture 20 in a horizontal direction and through apertures 26, 20 light rays, such as 6, Fig. 5, enter the camera lens. Light rays, such as 5, Fig. 5, enter the attachment through an aperture 31 and are reflected by mirrors 28, 27 before passing through aperture 20. The upper edge of aperture 31 is in horizontal alignment with the upper edge of aperture 26 and the vertical edge of mirror 27 which is nearer aperture 20 is in a plane which bisects said aperture vertically.
