Title: A lance pipe for the direct injection of oxygen in steel making
IPC: C21C5/46
Filed: 1963-07-19
Abstract: 1,056,105. Blowing lances. S. NISHI. July 19, 1963 [Feb. 4, 1963], No. 28665/63. Heading F4B. An oxygen lance comprises calorized inner and outer layers, 4 and 2 respectively, having respective mean aluminium concentrations by weight of between 28-33% and between 18- 26% to a depth of 0À1 mm. whereafter said concentrations taper off gradually to merge at the interfaces with the base iron or steel of the pipe 3, an outer porous refractory film 1 less than 2 mm. thick having a melting point above the operating temperature, and a thin inner refractory film 5 which is fluid below the operating temperature. Calcium carbonate is added to the refractory mix of the outer film to promote and ensure its porosity on decomposition of the carbonate whereby this film absorbs the thermal expansions and contractions of the pipe without separation therefrom, forms a heat shield and a base for slag adhesion to increase the insulation of the pipe. The inner film refractory mix may include boron in a suitable form such as borax to promote transformation into a glassy fluid state below the operating temperature whereby the said film flows downstream under the action of the throughput oxygen to form a protective film over the lance end. Both films are applied in paste form by mixing with water glass having a density within the range 25-35 BaumÚ, dried at below 100 C. an calcined at above 300 C

Title: Improvements in or relating to the catalytic polymerisation of ethylenically unsaturated hydrocarbons and to the preparation of catalysts therefor
IPC: C08F236/04
Filed: 1960-08-19
Abstract: A catalyst for polymerizing ethylenically unsaturated hydrocarbons is made by reacting (a) one or more vanadium tetrahalides with (b) a smaller molar quantity of one or more organometallic aluminium alkyl compounds to form one component of the catalyst, and mixing this component with a second component consisting of an organo-aluminium compound or compounds containing in the molecule aluminium bound to an alkoxy group or groups as well as to a hydrocarbon radical or radicals.  In (a), titanium tetrahalide may be present in admixture with the vanadium tetrahalide, e.g. the chloride or bromide. Component (b) may be AlOC2H5 (C2H5)2, AlOC8H17(C2H5)2, mixtures of Al C2H5)3 with AlOC8H17(C2H5)2, mixtures of AlOC8H17(C2H5)2 with Al(OC8H17)2C2H5 in molar ratios greater than 1, mixtures of Al (C2H5)3 with Al(OC8H17)2C2H5 in molar ratios exceeding 1/3 , and mixtures of Al(C2H5)3 with Al(OC8H17)3 in molar ratios greater than 1. In the polymerization of olefins, the second component of the catalyst may be added to the polymerizable mix either with the first component or subsequently.  The polymerization may be carried out continuously or batchwise, and it is preferably effected in the presence of an inert solvent or diluent such as iso-octane.  The polymerizations of a mixture of ethylene and propylene, propylene, isoprene, and butadiene, utilizing the above type of catalyst, are exemplified.  The polymers are purified by conventional techniques. Specification 875,735 is referred to.

Abstract: 1,079,158. Wells. TEXACO DEVELOPMENT CORPORATION. July 7, 1965 [July 13, 1964], No. 28864/65. Heading E1F. An underwater wellhead has a tubular guide 36 which also serves to supply fluid for controlling wellhead elements such as 28, 29 or for carrying out operations on the wellhead. A stack of blow-out preventers 26, 29 is lowered into position on the wellhead by means of a bracket 32 engaging guides 22, the stack being fixed to the casing 10 by a pressure-released connector 24. Control sleeves 44 on the bracket are connected to kill lines 42, and to conduits 94 leading fluid to operate the preventers 28, 29. The guides 36 are connected to the sleeves by joints 46, and a marine conductor 48 is connected to the stack by a pressure-operated connector 55, the guides 36 being lowered with the stack, and the conductor being subsequently lowered down the guides 36. A sleeve valve (76) (Fig. 2, not shown) in the sleeve permits fluid flow from the guides 36 to the kill lines (42), a tube (84) having a side outlet (88) and a closed lower end is arranged to engage the sleeve to prevent flow to the kill lines and direct fluid from the interior of the tube (84) to the conduits (94) to operate the preventers. The tube 84 may be replaced by a ball which may be permitted to fall and seat in the sleeve valve so that mud used to kill the well may be used to actuate the preventers. The guides 36, the conductor and the stack are supported by cables 62. The connector 55 permits emergency removal of the conductor from the well, and the joints 46 permit subsequent removal of the guides if necessary. The bracket (32) (Fig. 4, not shown) may have means (68) coacting with a bracket (66) on which a guide (36) is lowered to ensure realignment of the members (44), (46). The conductor may be dispensed with and the guides 36 may employed to guide drill pipe into the well. In a modification (Fig. 6, not shown) parts of the kill line and the conduits run through the base (100) so that the preventer stack may be removed and the guides (36) used to install a Christmas tree.
