Title: Process for the manufacture of cyclic ª‡-cyanketimides and cyclic cyanketones
IPC: C07C45/42
Filed: 1934-11-19
Abstract: Cyclic a -cyanketimides are produced by slowly adding a solution of an aliphatic straight chain o -dinitrile to a solution of a condensing agent having the formula <FORM:0438291/IV/1> in which R1 is aryl, R2 is a non-aryl residue and Me is an alkali metal.  In an example, tridecane1 : 13-dicarboxylic acid dinitrile in ether is run into an ethereal solution of sodium p  methylanilide which is prepared from methylaniline and sodium in the presence of ether and naphthalene.  The product is decomposed with water and distilled, 1-cyancyclotetradecanoneimide being obtained as the undistilled residue.  On hydrolysis with sulphuric acid, cyclotetradecanone is produced.  Lithium ethylanilide is mentioned as a condensing agent. The Specification as open to inspection under Sect. 91 comprises further examples: (1) pentadecane-1 : 15-dicarboxylic acid nitrile is condensed with sodium isoamylanilide, to give a cyanketimide which on hydrolysis yields cyclohexadecanone; (2) acelainic acid dinitrile is converted into cyancyclooctanoneimide.  This subject-matter does not appear in the Specification as accepted.
Patent GB-447759-A (GB)
Title: Method of and apparatus for the distillation of powdered material
IPC: C22B26/22
Filed: 1934-11-19
Abstract: Powdered material is vaporized by moving it upwardly into a zone where it is heated by downward radiant heat produced by an electric resistance heater, the surface layer of the powdered material being continuously renewed and the disengaged vapours withdrawn.  The process may be applied to chemical reactions wherein volatile material is produced from solid reactants such as in the extraction of <PICT:0447759/III/1> phosphorus and to the purification of substances other than metals with or without the use of a vacuum and at high or low temperatures.  Powder passes from a holder 1, through a double valve 11 into a pipe 12 along which it is fed by a screw conveyer 14 to a pot 17 in the heating chamber 18.  The surface layer of the powder in the pot 17 is exposed to the radiant heat of an electric resistance heater or heaters 23 which may be horizontal or, preferably, parallel to the surface layer of the powder. Gases and vapours pass through the outlet 22 which may be connected to a vacuum pump.  Spent powder spills over the edge of the pot 17 and is carried by a screw conveyer 29 into a pot 33 in a chamber 34.  The waste material is discharged from the chamber 34 by a screw conveyer 41. Inert or reducing gas may be introduced at 7 and 36 and the holder 1 may be connected to a vacuum pump by the pipe 4.  The charge in the pot 17 is gently agitated by the expansion of the indifferent gas or agitation may be effected mechanically by movement of the pot.  The evolved vapours are superheated by passing over the heating elements and may be further superheated.  When the apparatus is at or near atmospheric pressure, the chamber 34 and pot 33 may be omitted.

Title: Process for the production of solid substances in a finely divided state by volatilisation
IPC: C01G21/06
Filed: 1922-12-06
Abstract: The production of solid substances in a finely-divided state by volatilization is effected by causing the raw materials to be volatilized as they are passing over, or being otherwise brought into motion relative to, bodies of large superficial area.  The raw materials may be passed over such bodies either in the fused state or in the form of granules, and in the latter case motion may be applied to the bodies of large superficial area. Alternatively, the raw materials may be allowed to drizzle down a shaft packed with heat-resistant porous bodies.  Relative movement between the bodies of large superficial area and the raw materials may be produced in any other way, for example by means of perforated discs which are caused to gather or lift the raw material, or which may be flooded intermittently therewith.  In each case, sufficient heat is applied to effect volatilization, which may be accompanied by chemical change brought about by suitable reaction-gases.ALSO:The production of solid substances in a finely-divided state by volatilization is effected by causing the raw materials to be volatilized as they are passing over, or being otherwise brought into motion relative to, bodies of large superficial area.

Filed: 1922-12-11
Abstract: 217,251. Robertson, J. K., Duerden, S., and Strachan & Henshaw, Ltd. Dec. 11,1922. Registering webs.-A mechanism for automatically controlling the feed of a previously printed and re-wound web of material to a paper bagmaking or other machine comprises a pin-carrying roller engaging holes in a web of paper or other material, means for ensuring that the pins will enter the holes whether or not the holes occur at exactly regular intervals, and means for taking the tension off the section of the web in which the holes are engaged by the pins. In the arrangement shown, the web a passes from its reel b through the feed adjusting device to the draw rollers c of a paper bag-making machine. The feed device comprises three sets of rollers e - - - of which the rollers e, h and i have incomplete treads, all being driven bv a shaft d operated by a shaft on the bag-making machine. The roller g carries tapered pins j adapted to enter the holes in the web. The arrangement is such that the roller e intermittently feeds the paper at a slightly accelerated rate to ensure that the pins have a sufficient surplus supply of paper to adjust themselves accurately in the perforations without strain or tension, whereupon the paper is passed by the pins through the cut-away portion of the tread of the roller h. During this period the tension of the web from the draw rolls c is taken by the tread of the roller i in engagement with the roller g. As soon as the tread of the roller h again grips the paper, the rollers e and i come out of action enabling any surplus feed of paper on either side of the roller g to be absorbed.

Title: Bulked yarn
IPC: D02G1/16
Filed: 1974-07-31
Abstract: 1519587 Bulking yarn JOHN HEATHCOAT & CO Ltd 29 July 1975 [31 July 1974] 33834/74 Heading D1F  The degree of crystallinity of the filaments of a bulked multifilament yarn varies along the length of the filaments to provide alternating points of maximum and minimum interfilament density, the spacing between maxima and minima being up to 10 metres. The bulking and density alteration is produced by entraining a multifilament yarn in a stream of fluid at a temperature high enough to plasticise the yarn, projecting the yarn as a continuous operation against one end of an elongated package of already bulked yarn and causing the pressure at said one end of the package to fluctuate between a maximum and minimum value at a frequency per second of at least 1/600th the speed in metres per minute of the yarn just before it impacts said end of the package. The variation in density produces a variation in dyeability. If the spacing is 3cm or less the dyed yarn appears to be of constant colour but the colour is said to be more "lively" than that of a uniformly dyed yarn. If the spacing is 3cm to 10m a mottled effect is produced. The individual filaments may be crimped, more than 50% of the filaments having a maximum amplitude of undulation less than the diameter of the yarn, and after removal of any twist which may have existed in the yarn before crimping, more than 50% of each filament lies on one side of a diametral plane of the yarn particular to that filament. Preferably the crimping and the density variation is accomplished using the stuffer box crimper, Fig. 2, of Specification 1342484. In example I a 30 filament polyester yarn of 167 decitex per filament is fed at 1100 m/min using steam at 5.5 atmospheres and 185C. The bulked yarn is withdrawn at 880 m/sec (20% overfeed). There is no rhythmical change in dyeability. Increasing the steam temp. to 235 and the overfeed to 36% (ex. 2) or the steam pressure to 9 atmospheres (ex. 3) gives yarns with a 10cm separation between points of maximum dyeability. The bottom end of the yarn plug forms in portion 12A of the stuffer tube. Steam pressure increases and pushes the yarn plug upwards faster than it is built up by the addition of yarn until ports 13 are uncovered. The pressure drops, the plug build up covers ports 13 and the cycle is repeated. The pressure fluctuation produces a fluctuation in the tension of the yarn from nozzle 1 to portion 12A of the stuffer tube which in turn causes a fluctuation in the degree of separation of the filaments of the yarn and hence in the rate of heat transfer to the filaments. This produces the rhythmical change in the degree of crystallinity.
