Title: Introducing moving yarn into texturising nozzle - by delivering yarn to nozzle by suction and then repositioning nozzle for texturising
IPC: D02G1/16
Filed: 1979-04-09
Abstract: A moving yarn is introduced by hand into the delivery aperture of a texturising nozzle. It is brought past the aperture to a cutter by means of a mobile suction tube. When the yarn is brought to the immediate vicinity of the delivery aperture it displaces vertically in relation to the nozzle, which is not yet working. After cutting, the yarn is caught in an air current and passes into the aperture, to be led through the nozzle towards the suction device providing the current. Several yarns may be so handled, each fed into an aperture, and led to the common suction device. Drawing rollers supply the uncrimped yarn to a texturising nozzle. The nozzle may pivot through its feed tube held by a support from a texturising posn. (A) to a yarn introduction posn. (B). A pneumatic jack is jointed to the support through its piston rod to the articulation pivot. Simple means are provided for introducing and threading up a moving yarn without the need for any supplementary threading devices of any kind associated with or passing through the texturising nozzle.

Title: Rotor rotating rapidly in liq. - esp. ship's propeller, coated with polymer, avoiding wear due to cavitation
IPC: F04D29/02
Filed: 1980-11-03
Abstract: In a rotor which rotates at high speed in a liq. medium, esp. a ship's propeller, the surface in contact with the liq. is coated with a polymer. The polymer is esp. non-wettable. The coating is esp. of a polyethylene cpd., a poly-(haloethylene) cpd., a polyfluorocarbon, and partic. polytetrafluoroethylene (PTFE). The surface to be coated is cleaned, de-greased by heating to 400 deg.C and roughened, followed by appln. of a layer of a porous material. The porous material is esp. of alumina, or a Ni-Al alloy, partic. contg. 80% Ni and 20% Al. A primer is applied, followed by heating to not above 250 deg.C, followed finally by appln., by spraying, of a layer of polymer, esp. PTFE. The PTFE layer is sintered at 380 deg.C in a special polymerisation oven. Applicn. of the PTFE layer and sintering may be repeated to give a layer of the reqd. thickness. Wear, as a result of cavitation, is avoided. With coatings of 'Teflon' (RTM) no wear due to cavitation is seen after 350 hr. of rotation. 'Teflon' coatings are also anti-fouling, and give a very low coefft. of friction in the medium.

Title: Styrene prodn. from s-butyl-benzene - by oxidn. to acetophenone, hydrogenation to alpha-methyl-benzyl alcohol and dehydration
IPC: C07C29/145
Filed: 1981-03-19
Abstract: Prodn. of styrene (I) is carried out by (a) oxidising s-butylbenzene (II) with O2 in the presence of one or more metal cpds. as catalyst; (b) hydrogenating the resulting acetophenone (III); and (c) dehydrating the resulting alpha-methylbenzyl alcohol (IV). Step (a) is pref. effected using a catalyst comprising one or more Group Ib, IIb, IIIb, IVb, Vb, VIb, VIIb and/or VIII metal cpds. esp. an acetate, benzoate, naphthenate, stearate or bromide of Co, Mn, Ni or Cr. The catalyst is pref. used in an amt. of 0.001-1.0 wt.% based on (II). The reaction is pref. effected in a 2-5C fatty acid solvent (esp. acetic acid) at 80-150 deg.C and 0.5-50 kg/sq.cm. Step (b) is pref. effected in the liq. phase at 50-200 deg.C and 1-100 kg/sq.cm in the presence of a Pd, Ni or Cu-chromite catalyst. Step (c) is pref. effected at 180-300 deg.C at 900 mm Hg or less in the presence of an Al2O3, TiO2, SiO2-Al2O3, activated carbon, activated clay or organic sulphonic acid catalyst. The process gives high yields of high-purity (I) using (II) as starting material, which is less expensive than ethylbenzene.

Title: Gas discharge lamp assembly e.g. for reproduction camera - uses three concentric circular tubes in light box
IPC: G03B27/54
Filed: 1984-10-24
Abstract: The discharge tubes (22, 23, 24) are mounted concentrically inside a tray (25) let into the upper surface of a light box (20). Above the tubes is a glass light-diffusing panel (21). The transparency to be reproduced is laid on top of the panel. The output of a photosensitive detector (32) is fed to a control unit (26) which can independently control the su-plies to the three tubes. The detector output is amplified and compared with a reference voltage. The comparator output is used to control the current fed to the tubes via a thyristor switching unit. The reference voltage is produced by a d-a converter fed by an output from a microprocessor. The latter is also used to control other functions of the reproduction camera.
