摘要:
A power shift transmission (3) for motor vehicles in which instead of a hydrodynamic torque converter a controlled or regulated multiple disc clutch serves to assist starting. The loading of clutch is minimized by a fitted catch which prevents the motor vehicle from rolling in the opposite direction to the direction of travel intended by the gear selection. Catch can take the form of a mechanical catch, as sprag unit, or the form of an electronically adjusted catch which acts on one and/or more transmission brakes and/or clutches and/or into the service brake of the vehicle.

The invention relates to a transmission in which the input power is either directly transmitted by an input shaft (2) to an output shaft (17) or indirectly transmitted via a continuously variable transmission (5), in particular a transmission with toroidal races (6, 8 and 7, 9 respectively) which work together in pairs and between which rotate rolling bodies (10) and a planetary gear (18). According to the invention the first power range corresponds to a first forward travelling speed range in which the input power is transmitted via the variator (5) to the output shaft (17) and the planetary gear (18) revolves as a unit, and one other power range follows the first power range and corresponds to a range of higher forward travelling speeds in which the input power is divided and supplied to the planetary gear directly and via the variator (5) which totals and transmits it to the output shaft (17). By the plurality of possible arrangements, in particular of the variator and planetary gear, the transmission according to the invention is suitable for use in practically all vehicles.
摘要:
The power shift for vehicles has clutches and brakes in the form of multi-disc clutches which consist of disc sets; instead of the multi-disc brake for the reverse drive range, a form-locking clutch such as a disc synchronization is provided which in engaged state transmits the retaining torque via form locking and in disengaged state is freely rotatable and thus free of loss.

The invention relates to the use of n-hexadecyl n-nonanoate (CAS number 72934-15-7, hereafter cetyl nonanoate) and n-octadecyl n-nonanoate (CAS number 107647-13-2, hereafter stearyl nonanoate) and to the mixtures thereof (CAS number 878027-13-5) as fixatives for fragrance substances. The invention also relates to specific compositions comprising (A) cetyl nonanoate and/or stearyl nonanoate as well as (B) one or more fragrance substances. The invention also relates to a process for the preparation of such compositions as well as to (cosmetic) products comprising a composition according to the invention. The invention further relates to a process for imparting, intensifying or modifying an odor on (human) skin. A particular aspect of the present invention relates to the improvement in the adhesive strength of a composition according to the invention on (human) skin and/or (human) hair.

摘要:
An apparatus for applying a liquid to a moving web has an applicator element having a surface extending transverse to the web-travel direction and positioned to contact the moving web. Liquid applied to the surface is transferred to the moving web where the moving web contacts the surface. A support spaced in the web-travel direction from the applicator element has a plurality of guides extending transverse to the web-travel direction, with at least some of the guides overlapping others of the guides. Respective shields slidable in the guides transverse to the direction extend between the web and the surface so that where the shields extend between the moving web and the surface there is generally no transfer of the liquid from the surface to the moving web. Respective adjusters connected to the shields shift same in the respective guides between positions spaced from one another to positions at least partially overlapping one another.

Process for esterification of farnesol in an initial mixture comprising alpha-bisabolol, farnesol and optionally other components, with the following steps: 1. Preparation or production of the initial mixture, 2. Adding (i) a transesterification catalyst and (ii) one or more compounds of formula (B) R2YnCO2R1 (B) in which the following applies: R1 stands for an alkyl residue with 1 to 12 C atoms; R2 stands for hydrogen, an alkyl residue with 1 to 20 C atoms, a cycloalkyl residue with 5 to 20 C atoms, an aryl residue with 6 to 20 C atoms or a heteroaryl residue with 5 to 20 C atoms; and Y stands for CH2, CH(Me), CH(Et), C(Me)2, CH2—CH(Me), CH(Me)-CH2 or CH2—CH(Me)-CH2 and n stands for a whole number from 0 to 6; or R2 stands for a group CO2R3, R3 standing for an alkyl residue with 1 to 12 C atoms; and Y stands for CH2, CH(Me), CH(Et), C(Me)2, CH2—CH(Me), CH(Me)-CH2 or CH2—CH(Me)-CH2 and n stands for a whole number from 0 to 8, or Y stands for an optionally substituted phenyl or naphthyl ring with a total of at most four substituents on the ring, n=1 applying.
