Title: Oxygenated derivatives of olefin polymers
IPC: C08G65/26
Filed: 1965-03-23
Abstract: Products suitable for use as lubricating oil additives are obtained by reacting at least one alkylene oxide containing up to 4 carbon atoms with an olefin polymer formed from one or more olefins having 2-12 carbon atoms, and containing a reactive hydrogen atom (as defined). The preferred products correspond to the formula RCH2O(AO)xH, where x is from 1 to 100, R is a C30- 200 alkyl group and A is a C2- 4 alkylene group; these are the alkoxylation products of the polymer reactant RCHO or RCH2OH obtained by ozonolysis of an olefin polymer with subsequent reduction, the reactant RCHO, if used, being converted to RCH2OH before reaction with the alkylene oxide. The products may be added to a lubricant base in amounts of 0.5 to 20% by weight of the base; they serve as stabilizers, antioxidants, pour-point depressants, corrosion inhibitors, dispersing agents and viscosity modifiers.ALSO:Oxygenated derivatives of olefin polymers are prepared by reacting at least one alkylene oxide containing up to 4 carbon atoms with an olefin polymer formed from one or more olefins having 2-12 carbon atoms, and containing a reactive hydrogen atom, i.e. one which will react with an alkylene oxide in the presence of sodium hydroxide or an equivalent base. In a preferred embodiment, the polymer reactant is of the formula RCHO or RCH2OH where R is a C30- 200 alkyl radical, and 1 to 100 moles of alkylene oxide are reacted per mole of polymer reactant; when RCHO is used the reaction conditions are such that it is converted to RCH2OH in situ.  The reactants of the given formulae can be obtained by subjecting an olefin polymer (derived from a C2- 12 olefin) to ozonolysis with subsequent reduction.  Suitable olefins from which the polymer reactant may be derived include ethylene, propylene, isobutene, 1-butene, 2-butene, 1-pentene, 2-pentene, 1-hexene, 1-octene, 2-octene, 1-decene, 1-dodecene and 2-dodecene.  The reaction with the alkylene oxide, which preferably comprises ethylene oxide, is suitably effected in the presence of a strong base such as sodium or potassium hydroxide, metallic sodium or potassium sodium or potassium alkoxide wherein the alkyl moiety has 1-4 carbon atoms, or sodium or potassium hydride.  A solvent may optionally be present, e.g. aromatic or aliphatic hydrocarbons.  Examples illustrate the reaction of the ozonolysis product of polybutene with ethylene and propylene oxide, and of the ozonolysis products of polydodecene-1, ethylene-propylene copolymer and hexene-1-octene-1 copolymer with ethylene oxide.  The products are useful as lubricating oil additives.

Abstract: 628,164. Glass-washing machines. McIN ERNEY, P. W., and WAITE, M. J. May 8, 1947, No. 12509. [A Specification was laid open to inspection under Sect. 91 of the Acts, Nov. 28, 1947.] [Class 138(i)] [Also in Group XXX] In a machine for washing glasses and  similar articles a platform supporting an endless belt conveyer is removably mounted in a drainage trough, the  platform having a number of apertures some of which register with spraying jets fitted within the trough. As shown the platform 2 is of inverted U-section with an upper wall 3 and side walls 4. Supported near the ends are bearings 6 with cross shafts 7 and pulleys 8 for conveyer belts 11, which are preferably of V-section. The upper lengths of the conveyer belts 11 pass over the platform 2 and are spaced by guide rods 12. Side walls 13, 13a prevent lateral displacement of glasses carried forward on the conveyor. Both of these side walls may be mounted on the platform. Alternatively, one wall may be formed by extending the side of the trough 16. An open-ended washing chamber 17, of inverted U-section and preferably transparent, is mounted on top of the platform. The platform 2 and its associated conveyer mechanism are removably mounted within a drainage trough 16, the platform completely closing the top of the trough. The bottom of the trough may be inclined to a discharge outlet 21. The platform 2 has a number of longitudinally spaced apertures 23, some of which register with spraying jets 22 located in the base of the trough 16 and connected to a water supply pipe 41 and electric heater 26 by pipes 38, 39, respectively. The electric heater unit comprises switches 27 and an electric immersion heater element 36 inserted in a tubular water jacket 26 having a water supply pipe 37 and outlet pipe 38. Valves 29 control the water supply from pipe 41 to the spraying jets and to the electric heater. A pressure safety valve may be fitted to the heater. The conveyer may be driven by chain drive 48 from an electric motor 43 with reduction gear box 44. An intermediate driving shaft 46 mounted on the side of the trough 16 may be provided with a detachable coupling 47 to facilitate removal of the conveyer unit from the trough. A fine curtain of water sprayed from either end of the washing chamber may be utilised to prevent escape of steam. Partial drying of the glasses may be effected if desired by positioning the electric heater 26 immediately below the discharge end portion of the washing chamber 17. An inclined chute for delivery of glasses on to the conveyer may also be used.

Abstract: 549,633. Reverse gearing; ratchet clutches. SINCLAIR, H. May 24, 1941, No. 12544/42. Divided out of 6678/41. [Class 80 (ii)] A pair of shafts 20A, 21A, Fig. 1, which are driven from a single shaft 24A through reverse gearing are connected to the latter by reversible freewheel clutches 34A, 3bA, and means are provided so that the freewheel clutches are reversed when the gearing is reversed. As shown, compound gears 22A, 22B, and 23A, 23B, connected to the driven shafts 20A, 21A, by the freewheel clutches 34A, 35A, gear with one another and with gears 27A, 28A free on the driving shaft 24A. A clutch member 33 splined to the shaft 24A may be clutched either to gear 27A or 28A, to give forward or reverse driving to the shafts 20A, 21A. The striking yokes 55, 56, Fig. 5, controlling the freewheel clutches, and the yoke 57 controlling the clutch element 33 may be carried on a single operating shaft 58, the yokes 55, 56, being yieldingly actuated through springs 62, 63. Each reversible freewheel clutch comprises a sleeve 44, Fig. 3, fixed to a gear wheel and having two rows of clutch teeth 45, 46. A nut 39 carried on helical ribs 38 on the shaft has clutch teeth 43 and oppositely directed pivoted pawls 47, 48 to co-operate with the teeth 45, 46. It also has spur teeth 53. A slidable controlling sleeve 49 has teeth 52 engaging the teeth 53 and axially spaced teeth 54, circumferentially staggered thereto. A ring 40 fixed to the shaft has teeth 51. For forward driving the sleeve 49 is moved to the forward position F. Engagement between the teeth 51, 54, is such that the nut moves to the position in which 43, 46, engage. Should the shaft overrun the nut 39 moves to its extreme left hand position, Fig. 3, and free wheeling is permitted. When the sleeve 49 is in the reverse position R the shaft is driven by the engagement of the teeth 45 with the teeth 43, further movement of the nut 39 being prevented by the engagement of the teeth 51, 52. Should the shaft overrun then the nut 39 moves to the extreme right-hand position and freewheeling in this direction results. Specification 513,974 is referred to.

Title: A process for the preparation of halohydrins
IPC: C07C29/66
Filed: 1940-08-09
Abstract: <PICT:0569716/IV/1> p  The production of halohydrins by the reaction of hypohalogen acids with unsaturated compounds such as allyl chloride or olefines is effected with the pH maintained at 4.5-8. This inhibits the formation of halogenides.  In an example, an unsaturated halide such as allyl chloride and water are introduced at 10 and 11 respectively into a pipe 12, wherein they are mixed with reaction products from the reaction chamber 13 and the mixture is delivered by pump 14 and pipe 15 to the chamber 13 which receives dilute hypochlorous acid and some glycerol dichlorhydrin supplied to the reaction vessel by a pipe 16, the pH being maintained within the stated range.  The reaction product is withdrawn by a pipe 17 to a neutralizer 18.  If the contact period in the chamber 13 is insufficient, an additional storage or reaction chamber may be provided in the pipe 17.  Sodium hydroxide or the like is supplied to the neutralizer chamber 18 to raise the pH to 10-11.  The neutralized mixture is led to a separator 22 in which the small quantity of insoluble product (halides) is allowed to settle and is removed at 23, while the aqueous layer containing the dichlorhydrin is removed at 24, a part being byepassed to a pipe 25 and pump 28.  Chlorine is fed in at 26 and sodium hydroxide or the like may be fed in at 27 to maintain the desired pH in the reaction chamber.  Specifications 126,311, 128,578 and 128,635, [all in Class 2 (iii)], are referred to.
