摘要:
The invention relates to a method for dyeing keratin fibers, especially human hair. The inventive method comprises the following steps: optionally applying a pretreatment agent M1 to the fiber, using a dye M2 on the fiber which is optionally mixed immediately before application to the fiber from a component M2a, containing at least one oxidative dye pre-product of the developer type and/or an indole and/or indole derivative and a component M2b, containing an oxidative dye and/or an enzyme. If desired, a third agent M3 is added to the individual agents M2a or M2b before mixing them or to the mixture M2, and said dye M2 is rinsed from the fiber after a period of 5–10 minutes. At least one of the agents M1, M2a, M2b or M3 contains a compound from the vitamin B6 group. The invention further relates to hair pretreatment agents, to agents for dyeing keratin fibers, to their packing in corresponding kits and to the use thereof. The inventive compounds of the vitamin B6 group and their physiologically acceptable salts are useful as coupling components in the production of oxidative dyes that contain conventional developer and/or coupling compounds and/or indole and/or indole derivatives in a substrate appropriate for dyeing. The inventive compounds are further useful as active substances that improve the hair structure.
摘要:
A composition and method for using the composition for dyeing keratin fibers. The composition consists of indole/indoline hybrid dyes and hybrid dye precursors. More particularly, the indole/indoline hybrid dyes and hybrid dye precursors correspond to formula (I): X—S—Y (I) where X is a group derived from an indole or indoline derivative as a melanin precursor, Y is a group derived from an oxidation dye precursor of the secondary or primary intermediate type or an indole or indoline derivative as a melanin precursor; and S is a structural element which is common constituent of the groups X and Y, a direct bond or at least one spacer group. The composition may also be used to color human skin.

A connector for a hearing instrument, in particular a receiver-in-canal behind-the-ear hearing aid, is small and visually inconspicuous. The connector should be as invisible as possible on the hearing instrument as it is worn, and the connector allows a microphone arrangement favorable for directionality and sound pick-up. The connector is disposed on an earpiece tube, which defines a longitudinal direction at the connector. The connector is connected by insertion into a connector receptacle of a hearing instrument transversely to the longitudinal direction. The hearing instrument has a laterally arranged connector receptacle, into which a connector is inserted transversely to the longitudinal direction. Because of the transverse insertion, the connector can be arranged laterally on the housing and because of the lateral placement, the front end face of the housing is smaller and the housing is overall flatter. A microphone can be arranged on the end face instead of the connector so as to improve sound pick-up and directionality.

A rotation apparatus for rotationally molded shaped objects includes a receiving apparatus for receiving at least one negative mold, a holding apparatus for holding the receiving apparatus, and a drive unit for driving rotary motion of the receiving apparatus, wherein the receiving apparatus (1) is embodied as a sphere. The holding apparatus includes at least one support and guidance element (5) for supporting and guiding the receiving apparatus. The drive unit includes a drive element (9) that is arranged in the rotation apparatus and is connected in energy-transferring fashion to the receiving apparatus (1) to cause the sphere to rotate.
摘要:
A behind-the-ear hearing device has a housing with a plug-in connector on a sidewall of the housing for connecting to an earpiece tube or sound tube. The lateral arrangement of the plug-in connector moves the plug-in connector away from the exposed position on the front end face of the housing. This enables the front end face, which is generally visible, to be made smaller. Advantageously, at least two microphones are provided, with one microphone position in the vicinity of the front end face of the housing. The front microphone position is thus moved farther away from a position that may possibly be covered by the pinna, and the rear microphone position can also be moved farther toward the front. The microphone positions are thus approximately horizontal, which promotes the spatial resolution of the detected surrounding sound (directionality) by the signal processing of the hearing aid.

An ear piece is formed for insertion and placement in an external auditory canal, preferably for deep insertion and in close vicinity of a tympanic membrane inwardly bounding the auditory canal. The ear piece has an inflatable balloon which, when it is inflated, expands and braces against the walls of the auditory canal. When it is deflated, it may be withdrawn from the auditory canal. The ear piece has a receiver module with a sound generator and a connection to an exterior device (e.g., a hearing aid, an MP3 player, a cell phone). The receiver module is integrally formed with a pressure relief valve that allows the balloon to be deflated by external activation. A pull cord pulls a valve piston off a valve seat, whereupon the pressure in the balloon is relieved and the ear piece may be pulled out of the auditory canal.

For particularly good adaptation to a given hearing situation, an in-the-ear hearing device which has a housing with a channel in the housing that is designed as a through-opening for sound and air between the interior of the ear and the environment outside the ear, the channel is provided with a structural element for changing the size of the through-opening at at least one position. The structural element is a valve formed with electroactive material and the size of the through-opening is adjusted by application of a voltage to the valve.
