Abstract: The invention concerns a composition for a friction material, e.g. for a brake lining or clutch facing, of the type containing a fibrous reinforcement, a binder and various additives. 
     The friction material contains no asbestos, but has properties comparable with asbestos-based materials. The composition contains a thermoset binder, which may be based on a phenol-formaldehyde resin, or a heat and chemical resistant rubber, the binder making up 15 to 40% by volume of the material. The fibrous reinforcement is a mixture of an inorganic fibre selected from metal fibres, e.g. steel glass fibre, mineral wools manufactured from slags or naturally occuring rocks such as basalt, silica fibres and ceramic fibres of the alumino silicate type; with at least one organic fibrous material such as wood pulp, jute, sisal, cotton. 
     70 to 4 % by volume of the material consists of the fibrous reinforcement, preferably 50 to 10% by volume. The inorganic fibrous material is the main reinforcement of the friction material, the organic fibrous material providing integrity and strength during manufacture. I

Abstract: A process for reducing the residuat monomer level of a polymer latex prepared by emulsion polymerisation comprises exposing the latex in a separate vessel from that in which the main polymerisation has been carried out to conditions under which free radicals are produced by a secondary catalyst added to the latex, the said catalyst being oil soluble or having an oil soluble component. In a preferred embodiment a polymer latex prepared by the emulsion polymerisation of styrene alone or a mixture containing styrene having a residual styrene level not exceeding 0.1 % based on latex volume may be obtained.

Abstract: Poly(ester carbonate) polymers are prepared by reaction of bifunctional phenolates in an aqueous phase with phosgene and with the acyl halide of a bifunctional carboxylic acid halide such as terephthaloyl chloride in an organic solvent such as dichloromethane. At least a portion of the phosgene is reacted with the phenolate before or during reaction of the acid chloride with the phenolate to avoid the formation of polyester blocks which have limited solubility in the organic solvent. After reaction is complete, or at any stage wherein oligomers are formed, the aqueous phase can be cleanly removed and easily separated from the organic phase, and the organic phase readily washed free of by-products. The final polymer product is recovered from the washed organic phase and is colorless, substantially amorphous and melt processable, and has a high glass transition temperature.

Abstract: In order to improve cooling of an at least two-part guide vane support or carrier for gas turbines, at which deformations do not occur during any operating state and whose parting surface-connection flanges and connection elements are constructed such that they can withstand, essentially free of deformation, all bending moments resulting from the thermal stresses, it is proposed to design the cooling agent channels arranged within the wall of the guide vane support alternately over the circumference thereof as infeed lines or openings and/or outfeed lines or openings and containing connection channels leading to the individual guide vanes or blades. The guide vane support possesses an essentially conical configuration over its axial extent. At the guide vane support there are provided substantially comb-like slotted elements defining the parting surface-connection flanges and the individual comb-like slotted elements may comprise individual sheet metal members which are fixed, as by welding, to the guide vane support.

The devices (18) may be brought to grip the foil and also to expand the pleats so the cover will be opened. 
     Further devices (19) are arranged to grip the lower portion of the cover to open the latter fully and to pull the cover down along a cargo unit (20).

Abstract: in processes for detection and measuring a substance or condition in a fluid medium by the effect of the substance or condition on a light emitting substance, such as luminous microorganisms, disposed in the medium, a method and apparatus is provided for determining the effect of the medium on the light signal due to the medium absorbancy or other factor which is independent of the effect of the substance or condition on the light emitting substance. This is accomplished by deriving from the transmittance of the fluid medium using an external light source the expected transmittance of the fluid medium containing the light emitting substance according to the expression       
     where A is the absorbancy of the fluid, c is the concentration of the absorbing substance and D is the mean absorbtion path length of the photons emitted. The expected transmittancy is applied to the observed transmittancy of the test sample to obtain the transmittancy of the test sample independently of the optical effects of the medium. 
     A cell design is disclosed for determining the absorbancy of the fluid medium using a single instrument.
