  • Patent number: 6834908
    Abstract: For a cabriolet vehicle with a convertible top hatch which can be moved between a cover position and an open position for selectively covering and opening a convertible top compartment and with a roll bar which can be moved between a lowered position and a protective position and which can be coupled to the convertible top hatch for joint movement, a convertible top hatch transmission part is provided which transfers the driving force to the convertible top hatch which can be disengageably coupled to a roll bar movement part that produces movement apparatus of the roll bar so that roll bar is movement can be produced, simultaneously with motion of the convertible top hatch, that is in a different direction from that of the convertible top hatch during at least one segment of the motion of the convertible top hatch.
    Type: Grant

  • Patent number: 6515172
    Abstract: Process for the preparation of perfluorocarboxylic acids of the formula RF—COOH, salts thereof and esters thereof from perfluoroalkyl iodides of the formula RF′—I, in which RF and RF′ are cyclic, branched or linear, saturated or unsaturated perfluoroalkyl radicals, by activating the perfluoroalkyl iodides in the presence of oxygen and in organic solvents.

  • Patent number: 4948535
    Abstract: A process for the sulfation of primary free OH groups of partial esters of aliphatic polyhydric alcohols with SO.sub.3 is described. As solvent, use is made of at least one compound which has a boiling point of 40.degree. to 200.degree. C. at a pressure of 98 kPa, is liquid under the chosen reaction conditions and, in addition to at least one trivalent nitrogen atom, which is linked exclusively to carbon atoms, contains only carbon, hydrogen and optionally ether oxygen atoms. The sulfated partial esters and also their alkali of alkaline earth salts are obtained with a good color and good yield and without the formation of large quantities of salts which pollute the waste water. They may be used, for example, for detergent base materials, synthetic soaps and flotation agents.
