Title: Production of multiple wound packages formed of a plurality of textile threads
IPC: B65H54/32
Filed: 1959-10-30
Abstract: 926,983. Winding yarns. BARMER MASCHINENFABRIK A.G. Oct. 30, 1959 [Oct. 31, 1958], No. 36957/59. Classes 120 (2) and 120 (3). A package of synthetic threads consists of individual packages on a common tube, these packages being in contact with one another. Two threads are wound simultaneously side-byside on a tube by thread guides which have the same length of travel and are arranged to bring layers of each thread into abutment in a plane at right angles to the tube axis or on any other surface of revolution generated about the tube axis. The traversing means may be a rotary thread guide with two grooves or guide arms spaced apart by half the length of a double package. Such guide arms may be pivotable and under the control of a guide bar 35 pivoted at 36 and moved by a lever 39 in dependence on package growth through a bobbin support arm 14 so as to form a sloping side on each package. If necessary the thread guide arms 27, 28 may each be caused to overlap the travel of the other to ensure that the individual packages are formed in contact. Where precision-wound packages are produced, the extent of overlap of the thread guides may be varied. Conical packages may be formed.

Title: Improvements in or relating to the production of potassium nitrate
IPC: C01D9/10
Filed: 1930-12-22
Abstract: In the production of potassium nitrate from potassium chloride and ammonium nitrate in a cyclic process a solution saturated at say 50-70 DEG  C. with potassium carnallite, ammonium carnallite, potassium nitrate and potassium chloride has added thereto the requisite quantity of potassium chloride and water to obtain on cooling say to 20 DEG  C. a precipitate of pure potassium nitrate, which is separated.  To the mother liquor is then added ammonium nitrate, potassium carnallite and a solution of magnesium chloride or crystals thereof so that on evaporating the resulting solution to remove added water a quantity of ammonium carnallite corresponding to the amount of potassium nitrate obtained is precipitated, and a saturated mother liquor results ready for re-use.  In the second step of the process anhydrous magnesium chloride recovered from ammonium carnallite may replace the solution or crystals used, whereby the amount of evaporation necessary is reduced.  The ammonium carnallite may be treated by known methods to form, for re-use in the process, both magnesium chloride and ammonium nitrate.

IPC: H01J1/308
Filed: 1957-12-16
Abstract: 853,352. Discharge tubes ; cathode materials. METROPOLITAN-VICKERS ELECTRICAL CO. Ltd. Dec. 9, 1958 [Dec. 16, 1957], No. 39061/57. Class 39(1). A discharge tube includes a cathode comprising a body of homogeneous semi-conductor material and terminals or contacts at points spaced apart on the surface of said semiconductor body so that a voltage may be applied across it. The emission is stated to be due to a " hot electron " effect. Fields are required which, if applied for any length of time, would cause excessive heating of the semi-conductor lattice and disruption thereof. It is thus necessary to use a pulsed field of a maximum value less than the dielectric breakdown field of the particular material used. Some moderate heating of the lattice is advantageous as this leads to increased electron densities. It is also necessary to use semi-conductors with a sufficiently large forbidden energy gap to allow for high electron energies before avalanche breakdown sets in. Suggested suitable semi-conductors are the elements and compounds of the elements of Group IV of the periodic table, such as Ge, Si and SiC, which exhibit mobilities. The semi-conducting cathode may be coated with a substance of low work function, e.g. caesium. In one arrangement, Fig. 1, a disc 6 of semi-conductor material is mounted on an insulating block 7 carried on a base plate 1 of conducting material, e.g. copper, sealed by means of an insulating cylinder 3 to a plate 2 supporting a rod 4 carrying an anode disc 5. Conductor strips 8 and 9 extend from opposite edges of the disc 6 to a copper ring electrode 10 and the base plate 1 which are connected across a pulse generator 12. A high D.C. voltage is applied between the anode 5 and cathode 6 by a source 13. In an alternative embodiment, Fig. 2 (not shown), a rod of semi-conductor material is mounted axially in a conducting cylinder to form a diode. In a further alternative embodiment, Fig. 3, the semi-conductor material is in the form of a hollow cylinder 21 across which pulses are applied by a generator 12 connected to conducting rings 22 and 23. The anode 5 is supported by a rod 4 carried by an insulating plate 24. A disc 29, preferably of insulating material, is sealed across the ring 22. Additional accelerating electrodes similar to the ring 23 may be provided, Fig. 6 (not shown).

Title: Improvements in or relating to the preparation of gamma-phenoxybutyric acids and salts thereof
Inventor: REYNOLDS JOHN GERARD
IPC: B01J39/04
Filed: 1956-12-31
Abstract: Purified gamma phenoxybutyric acids, the phenyl group of which may be unsubstituted or substituted with two halogen groups or an alkyl and a halogen group, are obtained by reacting, in aqueous medium, an impure alkali metal salt of the acid with an ion exchanger solid capable of replacing metal ions by hydrogen ions and then separating the aqueous medium from the ion exchanger solid and purified phenoxybutyric acid.  The process is particularly applicable to the preparation of a purified gamma phenoxybutyric acid derived by reacting an alkali metal phenoxide with gamma chloro-butyronitrile followed by hydrolysis, or with gamma butyrolactone, or with an alkali metal salt of gamma chlorobutyric acid.  The ion exchanger solid and the impure alkali metal phenoxybutyrate are preferably employed in approximately chemically equivalent proportions.  The ion exchanger solid is preferably stirred with an aqueous solution of the impure alkali metal gamma phenoxybutyrate and the solid material filtered off. Any water-soluble impurities remaining in the solid material are preferably washed off with water and the purified phenoxybutyric acid separated from the ion exchanger solid with a suitable solvent, e.g. ether, acetone or an alcohol such as methyl, ethyl or isopropyl alcohol.  The solvent may then be removed from the extract by distillation.  When an alcohol is used as solvent it may also be used to esterify the phenoxybutyric acid using the acidic ion-exchanger solid as an esterification catalyst.  The mixture of ion-exchanger solid and purified phenoxybutyric acid may be treated with an organic or inorganic base or basic acting substance, to convert the acid into the corresponding salt of the base.  This reaction may be effected in a liquid reaction medium, e.g. an aqueous or aqueous alcoholic medium.  Suitable bases are mono-, di- or triethanolamines, ethylamine, isopropylamine, alkali metal hydroxides or alkali metal carbonates or bicarbonates.  After removing the purified gamma phenoxybutyric acid from the ion exchanger solid, the latter may be regenerated by treatment with a mineral acid such as hydrochloric or sulphuric acid.  Suitable ion-exchanger solids are the sulphonic acid cation-exchange resins and products obtained by condensing phenol, an aldehyde and a sulphonic acid or a sulphite. An example is given of the preparation of pure gamma (2-methyl-4-chlorophenoxy) butyric acid from impure sodium gamma (2 - methyl - 4 - chlorophenoxy) butyric acid, and details are given of its scorch effect at various concentrations on clover seedlings, when used as a selective weed killer.  Other compounds mentioned are gammaphenoxy butyric acid and gamma-(2 : 4-dichloro-phenoxy) butyric acid.  Specification 758,980 is referred to.
