Vaccine composition comprising at least two valences, one enhanced with adjuvant and not the other

Abstract: The invention concerns a vaccine composition comprising two valences; (i) a first valence which is adjuvant-enhanced with aluminium hydroxide and (ii) a second valence which contains a polysaccharide of bacterial capsule comprising one or more -O- acetyl groups and which is not adsorbed with aluminium oxide due to the presence of a protecting compound which may be a phosphate, a citrate or a carbonate and which prevents said adsorption. The first valence can be any vaccine valence. In one particular embodiment, the vaccine composition contains (i) the Hepatite A valence, adsorbed on aluminium hydroxide and (ii) the typhoid fever valence formed by the polysaccharide Vi of the Salmonella typhi capsule.

Microwave assisted hydrolysis of aluminium metal and preparation of high surface area γ Al 2 O 3 powder

Abstract: Phase pure boehmite particles were prepared by microwave assisted hydrolysis of aluminium sheets. These particles were calcined in air to produce γ Al2O3 particles with specific surface area of ~210 m2/g. The alumina particles were characterized by studying X-ray diffraction, transmission electron microscopy and Fourier transform infrared spectroscopy. For comparison, the aluminium hydroxide particles were also prepared by normal hydrolysis of aluminium metal. Normal hydrolysis yielded a mixture of boehmite and bayerite particles whereas microwave assisted hydrolysis produced phase pure boehmite particles. The importance of using microwave radiation for the hydrolysis of aluminium metal is also manifested in a shorter reaction time.

Prepreg and laminated board

Abstract: PROBLEM TO BE SOLVED: To provide a prepreg, which has a superior flame resistance and heat resistance and is made non-halogenated. SOLUTION: An epoxy resin, a curing agent, an aluminium hydroxide and an inorganic filler coated with a metallic molybdate are blended in an organic solvent. An epoxy resin varnish prepared by this is impregnated into a substrate and dried. As no halogen is contained in it, no toxic material is produced and the aluminium hydroxide secures a superior flame resistance, and also the inorganic filler coated with the metallic molybdate secures the superior flame resistance and heat resistance.

Alkyl-1-alkoxyethylphosphinous acid aluminium salts

Abstract: Alkyl-1-alkoxyethylphosphinous acid aluminium salts are produced in that alkyl-1-alkoxyethylphosphinous acids are reacted with aluminium hydroxide with a molar ratio from 3:1. The thus obtained aluminium phosphinates are used as flame-proofing agents in thermoplastic polymers, in particular polyesters.

Paste of remover for removing printing ink

Abstract: An ink erasing paste is prepared from rubbing agent (2-65 Wt%), shaping agent (3-40) and solvent (10-90). Said rubbing agent is the adhesive-type rubbing agent chosen from inorganic adhesive, organic adhesive and their mixture and/or the water-insoluble rubbing agent chosen from aluminium hydroxide, SiO2,calcium pyrophosphate, calcium hydrogen phosphate, calcium carbonate, etc.
