Title: Process for improving homo-and co-polymers of vinylidene chloride
IPC: C08L23/28
Filed: 1959-02-04
Abstract: Polymer compositions of good impact strengths comprise (1) 30 to 90 wt. per cent of a homopolymer or copolymer derived from at least 50 wt. per cent of vinylidene chloride and (2) 10 to 70 wt. per cent of a chlorinated polyolefine having a molecular weight of at least 10,000 and a chlorine content of 20 to 60 wt. per cent.  Compositions prepared by the process claimed in Specification 861,854 are disclaimed.  Vinilidene chloride copolymers specified are these with vinyl chloride, acrylonitrile, acrylic acid esters and mixtures thereof.  The polyolefine may be a homopolymer, e.g. of ethylene, propylene or butylene, or a copolymer of different olefines, e.g. ethylene and propylene and may be prepared by a high or low pressure process.  It should be substantially homogeneously chlorinated. Chlorination may be effected in a halo-hydrocarbon solvent.  The composition may also contain a sulphochlorination product of a polyolefine as specified above, and/or a polymer or copolymer of chloroprene. Other optional ingredients included in the exemplary compositions are dibutyl tin dithioglycollic acid 2-ethylhexyl ester and a lubricant based on montan wax.  The compositions may be pressure-, transfer-, injection- or extrusion-moulded, e.g. into foil, sheets, tubes, bands or rods.  Specific applications mentioned are bottles and electric cable sheathing or coil formers. Specifications 542,414, 735,030, 799,392, 799,832, 801,031, 819,867, 826,639, 828,938, 854,089 and 882,524 also are referred to.

Filed: 1916-03-22
Abstract: 104,913. Openshaw, J. R. March 22, 1916. Hanks, treating. - Relates to machines for shading or beating hanks, of the kind in which the hank is placed over a pair of rollers of which one is fixed in position while the other is carried by a rising and falling table actuated by a cam &c The machine is adapted for treating either short cotton hanks or long linen hanks, being provided, not only with the roller 18 mounted on the oscillating table 15<a>, but with two rollers 5<a>, 5<b>, at different heights, or with a single roller which may be adjusted. During the rising motion of the table, the roller 18 is rotated through a ratchet arrangement, the ratchet-wheel being secured to the roller and the pawls carried by a surrounding collar, which is rotated during the upward movement by friction with a spring arm or lever 26. Means are provided whereby the hanks are subjected to a predetermined number of beats, after which the roller 18 is automatically held in the raised position for a definite time to allow of the removal and replacement of the hanks, after which the beating operation is automatically resumed. The beating-roller 18 is held in the raised position by a hooked lever 27a operated in one direction by a spring, and in the opposite direction by a cam 31 on the face of a ratchet-wheel 32, the pawl of which is connected by a link 34 to an arm 35, which is operated through an arm 37 by the cams 13<a> used for operating the table 15<a>. The periods during which the lever 27a may hold the beating- roller in the raised position or allow it to fall are determined by the shape of the cam, which may be exchanged according to circumstances, or have its form altered by pegging sections to it or being made in parts adjustable on one another. To allow of a period being prolonged indefinitely during which the hanks may be changed or the beating operation continued, the shaft 36, carrying the arm 37 is connected to a pedal lever 38<a>, by operating which the pawls of the ratchet-wheel 32 are held stationary and the arm 37 out of range of the cams 13<a>. The machine may be duplicated on each side of a central framing.

Title: Improved method for adding a liquid to a viscous spinning solution
IPC: B01F15/02
Filed: 1955-02-15
Abstract: The method of the parent Specification (wherein a predetermined proportion of a low-viscosity liquid is added automatically and continuously to a stream of a viscous spinning solution by suction into a pipe through which a portion of the total flow of spinning solution is pumped by means of two gear pumps in tandem, the point of introduction being located between the pumps and the pump preceding this point having a smaller capacity than the one following the point of introduction) is improved in that the low-viscosity liquid is continuously injected into the central or axial portion of the stream of spinning solution flowing through the pipe and in the direction of flow of this stream.  As shown in Fig. 2, a portion of the total flow of spinning solution <PICT:0777990/IV(a)/1> flows through the horizontal pipe 13 of a T-connection 6 and the low-viscosity liquid flows through the vertical pipe 18 of the T-connection and the curved nozzle 21, the outlet of which is coaxial with the horizontal pipe 13 and points in the direction of flow of the spinning solution through this pipe.  The ends of the pipes 13, 18 are connected to the remainder of the spinning solution supply system and to the low-viscosity liquid supply system by the threaded collars 14, 15, 19 which engage the flanges 16, 17, 20 of the pipes 13, 18, the joints being sealed with gaskets in the usual manner.  The T-connection 6 may be entirely of glass.  The modification reduces the wear on the second or higher capacity pump.

Patent GB-495680-A (GB)
Title: Method of preparing a film of regenerated cellulose adapted to receive a mechanically-produced sound record
IPC: G11B11/00
Filed: 1938-02-14
Abstract: A mechanically-produced and optically-reproducible sound record is obtained by subjecting a film of a cellulose derivative such as an organic or inorganic ester to saponification at its surface to a depth sufficient for the reception of the record, and providing the surface of the layer of regenerated cellulose with a covering layer which is opaque to the light required for the reproducing and copying operations, the sound record being then mechanically produced on the film, e.g. by means of a V-shaped chisel.  The cellulose ester may be cellulose acetate or nitrate. The covering layer may be obtained by applying a sol, associated with a protective colloid, of a metal sulphide such as mercury sulphide, or Berlin blue, or colloidal carbon, or it may be obtained by applying a metal salt solution such as a nickel salt and then treating with a sulphide solution so as to obtain an insoluble metal sulphide.  As an alternative, the opaque coating may be obtained by treating the regenerated cellulose layer with a photosensitive diazonium compound, exposing it and causing the light-decomposition product to react with a mercurous salt whereby a mercury layer is produced on and in the regenerated cellulose layer. The mercury layer may be converted to a highly opaque silver layer by treatment with silver nitrate.  In the case of cellulose acetate, the saponification may be carried out with alcoholic caustic potash.  The Specification as open to inspection under Sect. 91 refers also to the use of benzyl and ethyl cellulose ether films.  This subject-matter does not appear in the Specification as accepted.
