Abstract: The invention concerns a process for controlling a CVT in a motor vehicle. In order to avoid an uncomfortable excitation of a transmission ratio change of the CVT when the driving speed is constant it is proposed that in the case of small accelerator pedal changes (<a) and in the case of changes in driving speed (S) occurring within a calibrated range (S1<S<S2) the transmission ratio of the CVT be held constant.

Abstract: The present invention relates to a packaging machine having at least one working station which has a lower and/or an upper tool, being vertically movable on lifting tables and the lifting table having

Abstract: A process for rapidly mixing phosgene and an amine in the gas phase to produce the corresponding isocyanate. Micro-structure mixers are used for the rapid mixing. The educts emerge from the micro-structure mixer in the form of thin free jets which mix very rapidly by diffusion and/or turbulence. As a result, the mixing operation is accelerated substantially as compared with conventional reactors. The isocyanate yield is also increased.

Abstract: The invention relates to a process for the adaptive correction of the shifting quality of an automatic transmission which is coupled to an engine and in which correcting elements acting on the pressure or oil throughput bring friction elements into engagement in the form of clutches or brake bands to carry out shifting processes, the line pressure impinged on by the correcting elements being registered by means of an electronic device and corrected as a function of various operating parameters.

Abstract: The invention relates to solutions of(A) from 3 to 60% by weight, based on the combined ether-polyol content, of separately prepared oligo-urethane ethers containing terminal OH.sup.- groups in the form of reaction products of(a) diisocyanates with(b) dialcohols having an average molecular weight of from 200 to 800, the stoichiometric ratio of (a) to (b) amounting to various values based on the average molecular weight of the dialcohols,in(B) polyether polyols containing at least 2 hydroxyl groups and having an average molecular weight of from 1000 to 12,000 and to their use in a proess for the production of polyurethane foams capable of being effectively flame-laminated and (high-frequency) welded without any adverse effect upon their other properties.

Abstract: Polyisocyanates are prepared by thermally splitting a carbamate corresponding to the formula:R.sup.1 (NH--CO--O--R.sup.2).sub.nin which R.sup.1, R.sup.2 and n are as defined herein into the corresponding isocyanate and alcohol. The splitting reaction is carried out at a temperature of from 150.degree. to 350.degree. C., at a pressure of from 0.001 to 20 bar and in the presence of an auxiliary agent. Suitable auxiliary agents are hydrogen chloride, organic acid chlorides, compounds having an alkylating effect and organotin (IV) chlorides. Inert solvents and catalysts may also be employed in the splitting products. The thus-produced isocyanate and alcohol are then separated, if necessary.

Abstract: Polyether polyols are made by alkoxylating a mixture which is from 20-80 weight % sucrose and 80-20 weight % formitol. The product polyether polyols have an average hydroxyl functionality of at least 3 and a hydroxyl number of from 28 to 1000. These polyether polyols are particularly useful for the production of rigid polyurethane foams.
