A process for preparing fiber-reinforced hydraulic composite material having a high mechanical resistance and durability is characterised by treating the hydraulic binder with compounds in solution (for example, carbonates and bicarbonates of ammonia or of alkaline and alkaline earth metals) at variable concentrations from 0.5 to 20 percent by weight and at different treating temperatures in the r...

1. Drive device for blinds or the like, having a drive shaft (5) which, through a planetary gear arrangement drives an output shaft (16) which has to be coupled to the blind and further comprising a first switching plate (48) driven by the planetary gear arrangement and equiaxial with the output shaft and co-operating with a limit switch (42), the switching member (44) of which is braced on an end...

1. Felt consisting of fibres of a glass material, the fibres being produced by passage of the material in the molten state through orifices disposed on the periphery of a centrifuge and possibly drawn out by gaseous currents surrounding the centrifuge, characterised in that the mass of particles of a diameter greater than ten times the mean diameter of the fibres constitutes less than 1% of the ma...

A disposable test strip device for detecting and measuring ethanol in aqueous solutions is disclosed. The test strip includes an inert support pad that contains a stabilized dry form of the enzyme alcohol oxidase, a material having peroxidative activity and an oxygen acceptor that reacts with hydrogen peroxide to give a compound of changed color. The use of this strip to determine ethanol levels c...

Collection bag comprises a plastic envelope combined with a urine-permeable material and e.g. a non-woven material. There is an absorbing laminate. This comprises an integrated tissue and superabsorbing polymer that on absorbing liq. becomes a gel. The outer flaps can be folded over the absorbing body. It unfolds as the gel absorbs liquid and expands.

The hydraulic proportioning valve, for use in lorries, contractor's machinery etc., has a housing with feed and return passages. The housing contains a movable plug with passages connecting the system alternately with the pressure and return passages in the housing. The plug is pilot-controlled by two throttles subjected to the total pressure drop across the valve, one of them being adjustable. A ...

This invention concerns an ice skate sharpening machine with at least two sharpening machines (4, 5) arranged alongside one another. A skate holder (8) is adjustable in a coordinate plane towards and across the sharpening machines' (4, 5) sharpening discs (16, 18, and 20). The skate holder's (8) movements are determined by a template (13), which is one of a set (11) of templates (13). The sharpen...
