Title: Measuring chain tension between a riser and buoyant tank
Inventor: KILLBOURN STUART
IPC: G01L1/10
Filed: 2009-09-18
Abstract: A system 9 for measuring the top tension of a marine hybrid riser supported by a buoyancy tank 3 whereby the tension is inferred from natural frequencies of the connection 4, such as a chain or a cable, between the upper riser assembly 5 and the buoyancy tank 3. The system 9 includes inertial sensing means or accelerometer for sensing the motion. The motion itself may be induced by an inertial means within the system or it may be caused by ambient conditions. Measured data may be sent to the surface via a cable or by a hydro-acoustic transmission system. The apparatus may record data and also contains the necessary processing and filtering means together with a power supply.

Title: Variable geometry turbine
Inventor: GARRETT STEPHEN
IPC: F01D17/16
Filed: 2008-03-20
Abstract: A turbocharger has a variable geometry turbine (1) of the swing vane kind. The vanes (24) are pivotally mounted on a vane carrier (23) and extend into an annular passageway (13) defined between a first surface (21) of the vane carrier and the turbine housing or the bearing housing. The carrier has a second surface (28) that is connected to a supporting wall (30) of the bearing housing (3) or the turbine housing (4) by means of a plurality of substantially radially extending key connections (41,43). These resist the rotational force applied to the carrier by the passage of the exhaust gas over the vanes and also permit thermal expansion of the vane carrier (23) relative to the supporting wall.

Title: Method of producing water-soluble aluminates from aluminium ore such as bauxite
IPC: C01F7/04
Filed: 1958-03-28
Abstract: Bauxite ore is mixed with sodium carbonate and lime, formed into granules of 1 to 3 mm. size, and sintered with solid fuel in the same size range to form soluble aluminate.  The fuel may be mixed with the other ingredients before granulating or added separately.  The lime, which should be sufficient to suppress sodium silicoaluminate formation, may amount to 10% by weight of the bauxite.  According to an example, a mixture of bauxite, sodium carbonate and lime was granulated at 40 DEG  C. with water and 10% by weight of coke was added.  The granules after drying were sintered at 280 DEG  C. and the sinter leached at 90 DEG  C.  Further examples illustrate the formation of granules of 8 to 10 m.m. size which were crushed to 1 to 3 mm., and the employment of Bayer liquor salts as the source of sodium carbonate.

Title: Vinyl halide polymerisation process
IPC: C08F267/02
Filed: 1958-03-28
Abstract: Vinyl halides are polymerized alone or together with monomers interpolymerizable therewith as an aqueous suspension containing as suspending agents, (1) a water-soluble interpolymer of maleic acid, anhydride, imide or partial ester thereof and (2) a di-fatty acid ester of a C1-4 alkyl glucoside having 10-20 carbon atoms in each fatty acid group.  The following features are preferred:-(a) the glucoside is a -alkyl, particularly a -methyl, and the fatty acid is lauric or oleic acid, decanoic, myristic, palmitic and stearic acids being also mentioned; (b) the water-soluble interpolymer is of maleic acid or maleic anhydride with vinyl acetate, ethylene, vinyl methyl ether and isobutylene being also mentioned; (c) the water-soluble interpolymer is esterified with 1-10 wt. per cent of an alkanol which may contain a saturated substituent, butanol, hexanol, 2-ethylhexanol or tetrahydrofurfuryl alcohol being specified.  It is stated that the glucoside suspending agent reduces the average particle size of a vinyl chloride polymer and increases its porosity.  The process of the invention may be applied to the homopolymerization of vinyl fluoride, chloride, bromide and mixtures thereof, and to the interpolymerization of these halides with vinyl acetate, propionate, butyrate, stearate and benzoate; methyl, ethyl, butyl, 2-ethylhexyl and allyl acrylates and methacrylates; acrylamide, acrylanilide and methacrylamide; acrylonitrile and methacrylonitrile; vinylidene chloride; trichloroethylene; and the methyl, ethyl, propyl, butyl, amyl, hexyl, heptyl, octyl, allyl and methallyl esters of maleic, fumaric and itaconic acids. In examples, lauryl peroxide is used as catalyst for the polymerization of vinyl chloride alone or with vinyl acetate or diethyl maleate in a vessel which is rotated end over end. Other catalysts mentioned are benzoyl, di-tbutyl and toluyl peroxides. Specifications 646,969 and 804,448 are referred to.
