Title: Apparatus for setting the position of hydraulic adjusting cylinders
IPC: F15B7/08
Filed: 1979-04-17
Abstract: An apparatus for setting the position of a device provided with a number of hydraulic adjusting cylinders operates by simultaneously supplying to the various cylinders quantities of hydraulic medium corresponding to the desired setting of the device.

Title: Cooling lamps
IPC: H01J61/24
Filed: 1980-03-13
Abstract: In low pressure mercury vapour discharge lamps it has been proposed to provide a heat sink to cool a small region of the lamp envelope and thereby to control the mercury vapour pressure at its optimum value. This invention provides a heat sink which avoids disadvantages of prior devices which are both cumbersome and cast undesirable shadows. It provides a cooling member 3 contacting a small area of the lamp 11 to conduct heat from it and a device 7 for dissipating the heat. The cooling member 3 is attached to the lamp by a readily releasable mount 9. It is arranged so that the mount 9, although in contact with the lamp extracts less heat from it than the cooling member 3, which, as shown, is in the form of a rod or post 5. Various different embodiments are disclosed. <IMAGE>

Title: Hydraulic cements
IPC: C04B24/00
Filed: 1980-08-13
Abstract: A modified hydraulic cement product comprises a hydraulic calcium silicate-based cement having a Blain surface area of at least 3,000 cm2/g, and/or an iron content of less than 2.5% by weight expressed in terms of the ferric oxide content of the dry cement, in which the cement has been treated with an additive comprising an aldehyde or an amide or substance convertible to an aldehyde or amide under the alkaline conditions prevailing in the cement before or during the setting reaction. Treated cement may be hydrated subsequent to or in parallel with the additive treatment to give hydrated products which characteristically exhibit modified cement morphologies, in particular fibrous cement morphologies, and generally also modified physical strength properties, e.g. tensile strengths of at least about 10 MN/m2 and compressive strengths of at least about 60 MN/m2, as compared with untreated hydrated cement products. The cements may be used with other materials including aggregates and also reinforcing elements and in preferred embodiments may be used in the production of pre-cast units for use in the construction industry. Additionally some treated products prior to hydration exhibit desirable properties: cement slurries with certain aldehydes, e.g. acetaldehyde, providing extrudable cement compositions, and treatment of cements with salicylaldehyde, particularly in the absence of water, providing a quick-set cement composition which may be hydrated subsequently.

Title: Prevention of Hydrogen Embrittlement of Metals in Corrosive Environments
IPC: C23F13/02
Filed: 1980-11-27
Abstract: Embrittlement of metal substrates in corrosive environments such as gas and oil pipelines caused by absorption of the hydrogen which is cathodically evolved during various corrosion processes is substantially prevented by providing an active substance in the vicinity of the metal substrate, and in electrical contact therewith, the active substance being one on which cathodic hydrogen evolution occurs in preference to the metal, thereby reducing the amount of hydrogen available for diffusion into the substrate. The active substrate is preferably a sulphide, for example FeS, or mixed sulphide, for example NiCo2S4, and is advantageously applied as a coating on the surface of the substrate, a further coating of, for example, a thermosetting resin, preferably being employed for mechanical and environmental protection.

Abstract: 806,286. Pyrophoric lighters. RACEK, A., and RAGANITSCH, J. Dec. 2, 1955, No. 34593/55. Class 75(3) In a pyrophoric lighter having a hinged cover 1 which can be swung open by finger pressure and the short end of which is swung into an aperture of a side wall 9 of a casing as the cover is moved to the open position a closing flap 5 associated with the aperture is longitudinally slidably guided between the friction wheel carrier 2 and the casing side wall 9 and is articulated to the short end of the hinged cover 1. The edge 7 of cheeks 8 of the cover 1 hold the flap against the side wall 9 when the cover 1 is in the closed position. An inwardly bent transverse edge 10 on the flap 5- engages the transverse edge of the aperture in the side wall 9 to prevent the flap 5 pivoting outwards when in the closed position. When the flint is to be replaced the friction wheel carrier 2 is pulled out of the casing to the position shown in Fig. 3 to expose an opening in the flint guide tube. The flap 5 in the position shown in Fig. 3 can be swung up to enable the friction wheel to be cleaned.

Title: Making cathodes for sodium- sulphur cells
IPC: H01M10/39
Filed: 1981-03-18
Abstract: A cathode structure for a sodium sulphur cell is formed by impregnating with liquid sulphur a sheet of fibrous electronically-conductive material, e.g. carbon fibre material having fibres extending in random directions parallel to the plane of the sheet, and then forming, from the sheet, a plurality of similarly-sized apertured elements preferably of hexagonal external form. These elements are then threaded on a central support to lie closely adjacent to one another and compressed, whilst the sulphur is molten, between mould parts forming a cylindrical mould coaxial with the support. The compressed elements are then cooled to solidify the sulphur thereby forming an annular assembly of elements for fitting in the cathodic region of a cylindrical sodium sulphur cell.

Title: Methanol synthesis
IPC: C07C29/151
Filed: 1981-08-11
Abstract: A method and plant are disclosed for synthesising methanol from synthesis gas in which crude product methanol is vaporised and superheated and the resulting superheated crude methanol vapour is then expanded through a turbine which can be used to drive one of the synthesis gas compressors. Typically such synthesis gas is obtained by steam reforming of a hydrocarbon feedstock in a reformer furnace, waste heat generated in the reforming process being used to vaporise and/or superheat the crude methanol vapour. A turbine-compressor set may advantageously be used to compress air for combustion in the reformer furnace, the pass out air from the compressor being heated by heat exchange with hot combustion products from the combustion section of the reformer furnace and expanded through turbine prior to delivery to the combustion air duct. Additional power is available from the combustion air turbine for driving one of the synthesis gas compressor stages.
