An aqueous dispersion of silicic anhydride, comprising an aqueous solvent and silicic anhydride dispersed therein, wherein the silicic anhydride has a surfacial silanol group density of from 0.3 to 3 per 100 ANGSTROM 2 and is obtained by the surface treatment of silicic anhydride produced by a dry method.

PURPOSE:To check easily the constituting including packages, which are not objects of initialization, with a small-scale service processor (SVP) by using a correct answer value of the number of mounted packages as data to be stored in the SVP. CONSTITUTION:At the power-on time, an SVP 5 checks mounting signals from packages 1A, 1B, 2A-2C of processing units 1 and 2 through an SVP adapter 4 and a b...

A portable analyzer (10) is disclosed. The analyzer comprises in combination a housing (12), an optical system comprising a light source (10), a detector (16), and one or more means (18) for activating the optical system in generating a signal in response to a test element, means (45) for manually moving the test element (33) from a first position to a second position corresponding to a point of i...

For manufacturing molded and impregnated parts from epoxy resin compositions, a reactive epoxy resin is employed which hardens more slowly at higher temperatures (120 DEG to 180 DEG C.) than at lower temperatures (80 DEG to 110 DEG C.). The reactive epoxy resin composition is applied at the higher temperature and subsequently hardened at the lower temperature. According to the method of the in...

A gear wheel shaft assembly in which the gear wheel (4) is pressed against an end plane (8) of a shaft (1) by a central bolt (5) through the gear wheel. The end plane is situated at a smaller radius than a shaft bearing (2). The cooperating surfaces (8,9) may be sand blasted.

Fibre-reinforced foam bodies, in particular those which have a high fibre content (15-30% by weight or more), are produced by dispersing fibres in a liquid, generally water, together with surfactants and gases or gas- evolving agents, fillers, etc., and, in addition, by adding substances which increase the viscosity of the liquid such that it is not less than 40 cP at least during the foaming stag...
