Abstract: Silicatein is an enzyme of silicate-forming organisms used for the synthesis of their silicate scaffold. The present invention relates to the use of highly-expressed and highly active recombinant silicatein, silicatein isolated from natural sources after gene induction as well as silicatein-fusion proteins for the synthesis of amorphous silicon dioxide (silicic acids and silicates), siloxanes as well as modification of these compounds and their technical use.

Abstract: An actuating means adapted for fluid activation has a contractile hose terminally secured by clamping on at least one head piece. The contractile hose fits into an annular clamping gap or nip, whose wall bears saw tooth serrations, the saw tooth serrated areas being so arranged that their teeth are radially opposite each other and arranged in pairs each at the same level. The outer saw tooth serrated area is located on a compression sleeve, which is radially pressed to join it with the hose end section surrounded by it.

The head pieces bear against each other via supporting means permitting relative rotatability thereof in Abstract of the Disclosure such a manner that they are prevented from performing an axial relative movement involving mutual motion toward or away from the one another. When the interior space of the hose body is put under pressure a relative rotary movement between the two head pieces is caused.

Abstract: It is a question of an actuating means adapted to be activated by fluid power, which comprises a hose body (5) extending between two spaced head pieces (3 and 4) and whose interior space is able to be subjected to a fluid medium. A strand structure (6) fixed to both head pieces (3 and 4) and extending coaxially in relation to the hose body has two strand groups (18 and 19) in a crossover configuration with bendingly flexible strands (7) extending adjacent to one another with the same longitudinal alignment within a strand group. An intermediately placed yielding material (22) between the strand groups (18 and 19) serves to maintain the strand groups constantly at a distance apart.
