Patent DE-392309-T1 (DE)
IPC: E02D7/16
Filed: 1990-04-02
Abstract: A machine for pile-driving comprises a driving chassis (3) with wheels (5,6) for moving on railway or road, and an upper part (4) pivotally mounted about a vertical swivel axis (13) on the driving chassis. A mast (15) with slide guide (17) for a hammer mechanism (16) is connected to the upper part. The mast may be erected to substantially vertical position for the purpose of pile-driving and may be lowered into substantially horizontal position for the purpose of transport. According to the invention the mast is connected to the upper part by a telescopically extensible and contractible boom having a base part (28) being connected to the upper part of the machine by means of a hinge with a hinge axis (44) perpendicularly to the swivel axis of the upper part, and a telescopically extensible part (29) connected to the base part, said mast being mounted to said part (29) by a hinge having its axis (49) substantially parallel to the hinge axis of the base part. It is hereby achieved that the mast may be erected while the vehicle is standing on a track above which an electric overhead traction wire is mounted. The invention also relates to a method for transport and erection of such a machine and a method for placing of foundations next to a railway track.

IPC: D21F1/10
Filed: 1991-03-15
Abstract: A papermakers fabric having a system of flat monofilament machine direction yarns 22,23 (hereinafter MD yarns) interwoven with a system of cross machine direction yarns 21a,21b (hereinafter CMD yarns). The MD yarns 22,23 have an aspect ratio of greater than 3:1. Furthermore the MD yarns are vertically stacked with at least paired upper 22 and lower 23 MD yarns which weave over and under CMD yarns 21a,21b in such a manner that when a lower MD yarn 23 weaves over a CMD yarn 21a an upper MD yarn 22 is weaving (or floating) over the lower MD yarn 23. This ensures that no knuckles are apparent on the upper surface of the fabric. The weave gives rise to a warp-fill in the range of 80-125%.

Title: Weather-stable titanium dioxide pigment and method for the production thereof
Inventor: BLUEMEL SIEGFRIED
IPC: C09D7/48
Filed: 2005-06-23
Abstract: The invention relates to a weather resistant titanium dioxide pigment with good optical properties having a SiO2 dense skin doped with metal atoms. Particularly suitable elements for doping are tin, zirconium and titanium. The SiO2 dense skin is composed of multiple layers whereby the innermost layer does not contain any significant quantity of metal atoms. The coating according to the invention is produced by adding the components to the alkaline suspension (pH at least 9) one after the other with a sliding pH. Complete formation of the doped SiO2 dense skin requires that the pH subsequently be lowered to below 9. The pigment is particularly suitable for use in surface coatings and plastics.

Abstract: The present invention provides a method of modifying the surface of a polymeric substrate, e.g., to improve the wettability of the polymer film surface and/or alter the reactivity of the surface of the substrate by further oxidation or affixation of nitrogen, comprising exposing the substrate to a flame. The flame is supported by a fuel and oxidizer mixture that includes an effective amount, for modifying the polymeric substrate, of at least one compound that functions as a fuel or oxidizer substitute and is selected from an oxygen-containing compound, in which the oxygen comprises between about 10 and 50 atomic percent of the compound, a nitrogen-containing compound or an oxygen-nitrogen-containing compound. In a preferred embodiment, which affixes nitrogen or nitrogen-containing chemical groups onto the surface of the film, the flame is supported by a fuel and oxidizer mixture that includes ammonia, nitrous oxide, nitric oxide or a mixture thereof in an effective amount. Large increases in the ASTM wetting test, e.g., greater than 13 mJ/m2 over that reported with conventional flame-treating processes, have been observed in films treated according to this invention. In addition, significant increases in polymer film surface oxidation levels, e.g., as much as 55 percent, have been observed, as have significant amounts of nitrogen and nitrogen-containing chemical groups affixed to film surfaces.\!
