Title: Process for preparing submicron fibers of amorphous silica and submicron fibers of amorphous silica prepared in such a manner
Inventor: MACÁK JAN M
IPC: D01F9/00
Filed: 2015-09-11
Abstract: The process for preparing submicron fibers of amorphous silica with diameter in the range of 500 to 3000 nm according to the present invention is characterized in that there is first prepared a precursor solution containing 1.1 to 24 percent by weight of tetraethyl orthosilicate or tetramethyl orthosilicate or a mixture thereof as SiOi2i precursor, 4 to 20 percent by weight of polyvinyl pyrolidone with molecular weight in the range of 40 000 to 1 300 000 g/mol or polyvinyl alcohol with molecular weight in the range of 31 000 to 186 000 g/mol or a mixture thereof as a carrier polymer. The weight ratio of the SiOi2 precursor or that of the SiOi2 precursor mixture and that of the carrier polymer or a mixture of polymers in the precursor solution is in the range of 0.1:1 to 3:1, 2 to 4 percent by weight of lactic acid as a stabilizing agent, 2 to 87.9 percent by weight of ethanol and 5 to 50 percent by weight of n-butanol as a solvent. Subsequently, the above-indicated precursor solution is transformed by centrifugal spinning to precursor fibers, which are calcined at a temperature in the range of 300 to 1400 degC, to thereby removing their organic components therefrom and the SiOi2 precursor/precursors are transformed to amorphous state, which retains fibrous structure of the precursor fibers. The invention also relates to submicron fibers of amorphous silica with diameters in the range of 500 to 3000 nm that are prepared in the above-described process and which have specific area greater than 100 me2/g, preferably greater than 500 me2/g.

Title: Measuring machine for measuring the spacing and/or the direction of chain studs or teeth on endless roller chains or toothed (timing) belts
IPC: G01B5/16
Filed: 1988-02-11
Granted: 1988-11-24
Abstract: The roller chain to be measured is guided away in a releasing plane over deflecting rollers and over a guide rail. One roller can be driven in a rotating fashion, and one can be displaced with a defined force and is used to apply the prescribed clamping force. Provided outside the endless loop and opposite the guide rail is a measuring head which can be moved to and fro and has at least one pair of sensors and can be immersed between the chain studs. In order to increase the measurement accuracy of the chain spacing measuring machine, the drive roller, the guide rail and the tension pulley are arranged immediately juxtaposed, so that they form an approximately rectilinear measuring strand (side); the direction of rotation of the drive roller is selected such that the roller chain runs directly into the measuring strand from the drive roller. Various measures are taken in order to ensure an absolutely parallel alignment of the tension pulley and the drive roller even under the influence of the chain clamping force. The chain is guided in the region of the tension pulley in such a way that the tension pulley is wrapped around in all positions relative to 180@. Moreover, the direction of displacement of the tension pulley is parallel to the measuring strand. It is therefore possible for the chain clamping force required in the measurement to be adjusted in a way which can be reproduced accurately. Various design details of the ...
