Title: 3',6'-dihydroxy-5(6)-nitrospiro[2-benzofuran-3,9'-xanthene]-1-one mixt. by reacting 4-nitrophthalic acid/anhydride & benzene-1,3-diol in methanesulphonic acid
Inventor: WHARTON STUART
IPC: C09B57/00
Filed: 2009-02-12
Abstract: A mixture of 3',6'-dihydroxy-6-nitrospiro[2-benzofuran-3,9'-xanthene]-1-one (also known as 5-nitrofluorescein) and 3',6'-dihydroxy-5-nitrospiro[2-benzofuran-3,9'-xanthene]-1-one may be prepared by reacting 4-nitrophthalic acid (or 4-nitrophthalic anhydride) with benzene-1,3-diol (resorcinol) in methanesulphonic acid. Preferably, the methanesulphonic acid is substantially pure (being not less than 95% w/w), and in a ratio of 2 to 10 v/w relative to the nitrophthalic acid/anhydride. The reaction may be conducted at 60° to 120°C and quenched by adding it to a solvent, such as water, to precipitate the product. The ratio of water to methanesulphonic acid is preferably 4.5 w/w or less, the temperature of the water is preferably 0° to 10°C before quenching and the aqueous phase is maintained no higher than 30°C during quenching. The product may be isolated by filtration or centrifugation, and dried in vacuum at up to 70°C. The isolated product may be repeatedly heated in water at 80° to 100°C with agitation in order to reduce the level of phenolic esters of methanesulphonic acid (e.g. to below 5%) by hydrolysis of such esters. The thus obtained nitrofluoresceins may be used to prepare fluorescein 5-isothiocyanate and fluorescein lisicol (cholyl-lysylfluorescein, CLF).

Title: Shimmy damper for aircraft landing gear
Inventor: LUCE WILLIAM
IPC: B64C25/50
Filed: 2009-03-05
Abstract: A non-hydraulic shimmy damper 2 that is mountable to an existing aircraft landing gear 3 comprises a rotatable coupling member 75 in the form of a toothed wheel which engages with mating teeth of a steering gear within a gear cover 18. An adjustable biasing mechanism 26 ensures that the shimmy damper is biased into engagement with a steering collar 12. A disc 85 is rotatable connected with coupling member 75 and has a flat engagement area 90 that is compresses on both sides by friction pads 95,100. Friction between the pads and the engagement area provides a damping force that resists rotation of both coupling member and steering member. The pressure exerted by the pads is adjusted by a threaded cap assembly 115 acting on spring discs 122. The damping assembly is adjustable so that a desired amount of damping force can be applied and/or maintained. When the shimmy damper requires maintenance it can be readily swapped out as a line-replaceable unit (LRU) thereby reducing aircraft downtime.

Title: Process for forming carbon fibre reinforced ceramic composite
Inventor: FARIA JULIO JOSEPH
IPC: C04B35/528
Filed: 2009-11-09
Abstract: A process for forming carbon-fibre/ceramic composite materials, particularly suited for use in brake and clutch discs is disclosed. The process comprises steps in which either a powdered ceramic material such as silicon carbide and/or other carbides, oxides, nitrides; or elemental components such as silicon that may be converted by reaction with carbon to form powdered ceramics are dispersed, for example in powder form or using a liquid carrier, throughout the interstices in layers of carbon-fibre mat. The ceramic powder and elemental precursor dispersed in the interstices forms 10-50% in total of the final composite product. Layers of the carbon fibre mat may then be compressed and clamped together. As an alternative to clamping discreet layers, one or more long strips of carbon-fibre mat are similarly loaded with powdered materials and tightly wound onto a mandrel. Densifying carbon may then be deposited into the residual voids in the structure using either vapour phase infiltration or liquid infiltration followed by polymerisation and/or pyrolysis.

Abstract: 741,616. Luminescent materials. ELECTRIC & MUSICAL INDUSTRIES, Ltd. March 12, 1954 [April 15, 1953], No. 10239/53. Class 39 (1). A method of manufacturing phosphorus activated zinc sulphide for fluorescent screens in cathode-ray tubes, fluorescent lamps, &c., comprises heating zinc sulphide in an atmosphere containing phosphine. The phosphine can be carried by an inert gas such as nitrogen. The zinc sulphide may be mixed with finelydivided red phosphorus or a compound thereof such as diammonium hydrogen phosphate and, if desired, with a flux. By controlling the .concentration of phosphine during the heating operation the ratio of yellow to blue emission of the material can be varied, the ratio increasing with increasing phosphine to produce a range of colours from blue through white to yellow. In the example described 100 grs. of pure zinc sulphide and 4 grs. of diammonium hydrogen phosphate are mixed with pure water into a paste with a flux comprising 10 grs. of magnesium chloride (MgCl 2 .6H 2 O) and 3 grs. of sodium chloride. The mix is dried at 130- 150‹ C. for about 5 hours and thereafter fired for 30 minutes at a temperature of 950‹ C. in an atmosphere of nitrogen mixed with phosphine. The atmosphere should contain about 10 per cent of phosphine for the production of a white fluorescing material. After firing the material is cooled to room temperature in an atmosphere of nitrogen, removed from the furnace, washed, dried and comminuted. The phosphine can be prepared by the action of dilute sulphuric acid on zinc phosphide. Specification 658,748 is referred to.
