Granted: 1990-11-13
Abstract: Abstract of the disclosure The novel urethanes correspond to the formula I below   in which a denotes a number from 5 to 17 and b denotes a number from 1 to 7.  These urethanes are prepared by re-acting the corresponding perfluoroalkylethanol/epichloro-hydrin adducts with toluelene diisocyanates.  The novel aqueous dispersions are essentially composed of the novel urethanes, cationic or betaine emulsifiers and non-ionic emulsifiers, water-insoluble carboxylic and/or dicarboxylic acid esters and alkanediols or polyalkanediols which can be etherified on one or both sides, in water.            The novel urethanes and the novel aqueous dispersions are used to impart an oleophobic and hydrophobic finish to textiles, leather and furs.  They are also suitable for the treatment of unpainted timber, for example unpainted furniture.

Title: Process for producing high-quality steel
Inventor: SCHLEIMER FRANCOIS
IPC: C21C5/32
Filed: 1986-11-05
Granted: 1991-09-17
Abstract: ABSTRACT         The  invention  is  concerned  with  a process  for producing high-quality steel having a pre-selected carbon content from a melt.  The process of the invention comprises decarburizing a melt in a converter by top-blowing the melt with oxygen such that the carbon content of the melt is lowered to less than about 0.1% carbon. A slag is created on the melt and carbon is delivered into the melt at a high velocity whereby the melt and the slag mix, the carbon being delivered to the melt until the oxygen content of the melt is less than or equal to about 250-400 ppm oxygen and the carbon content of the melt is greater than or equal to about 0.04-0.07%  carbon.   Recarburization  of  the  melt  is  then effected in either the converter or a ladle whereby a melt containing as little oxygen as  is reasonably possible and having a carbon content which is as close as possible to a pre-selected carbon  content  is  achieved.   the  melt  upon meeting such requirements is finally transferred to a ladle and treated both with a synthetic slag and with a material that is both deoxidizing and desulphurizing.

Abstract: Abstract A multi-partite clamp structure includes two standard parts and a band of a length depending on the desired diameter of the clamp structure in the installed condition when tightened about an object to be fastened.  Two parts formed by two band portions are operable to be mechanically connected with each other in the area of overlap thereof by at least one outwardly extending hook device in the inner band portion engaging in an aperture in the outer band portion.  A respective band portion is mechanically connected with the corresponding end of the band by a hook engaging in an aperture, and the inner and outer band portions are provided with a tool-engaging device offering substantial resistance in the circumferential direction, whereby clamp structures of different diameter can be obtained by choosing a suitable length of band.

Abstract: ABSTRACT OF THE DISCLOSURE            "MOBILE SANITARY UNIT"      This invention relates to a mobile sanitary unit, which can function autonomously and in any site. The unit comprises a sealed aseptic container with the dimensions of a standard 20-foot container. The container has a door giving access to an opera-ting theater, changing facilities, and storage cup-boards. An electrical supply unit is disposed in a housing in the front wall of the container, for connection to an external generator. The unit inclu-des telescopic legs at all four corners of the con-tainer mounted on supports which may be folded flat against the container wall for transport, and deployed so that the container may be on-loaded and then off-loaded and used on site standing on its legs. The unit may be transported by an articulated truck comprising a tractor and low-platform semi-trailer. An electrical generator set is mounted on the saddle of the semi-trailer. The unit may also be transported by air and its weight of 3.5 tonnes enables it to be dropped by parachute.       Figure 4
