A method and apparatus for use at the stage of a radial tire building process at which a tread and breaker, and sidewall rubbers, are added to the expanded carcass. A tread assembly is built, comprising tread rubber breaker and sidewall rubbers and is then located around the carcass which is then expanded into the tread assembly. A tread assembly former has a central portion expansible to bring si...

The invention relates to a new anti-cancer chemical compound which has been called rooperol and certain derivatives thereof of the general formula in which A is chosen from the group including a phenyl group, a substituted phenyl group and -CH2-O-R5 where R5=H, an alkyl (C1-C5), aralkyl or acyl substituent; R1 and R2 are chosen from substituents including H for both or singly if one of ...

A nozzle ring of an extruder for blowing tubular plastics film is divided into cooling sectors provided with adjusting elements. The thicknesses of the blown film are measured over the circumference thereof and a number of film sectors of equal circumferential length corresponding to the number of cooling sectors is established from the measured thicknesses. Assuming that the film sector of maximu...

Process for preparing Xanthomonas heteropolysaccharide from Xanthomonas campestris NCIB 11854 and use of the latter, e.g. as viscosity modifier in an aqueous solution, and in a drilling fluid and use in connection with well treatments, and enhanced oil recovery.
