摘要:
A system for aligning and connecting adjacent distribution devices is disclosed. At least two mutually opposite side walls, which preferably run parallel to one another, of the housing of each distribution device have associated alignment and connection means. The alignment and connection means associated with the directly adjoining side walls of the distribution devices align in each case directly adjacent distribution devices with respect to one another in the horizontal direction and/or in the vertical direction connect each to one another.

A sealing and strain relief device having at least one sealing element is disclosed. The device is arranged in the manner of a sandwich between outer, plate-like bearing elements made from a relatively hard or rigid material and which is made from a relatively soft or elastic material. Slots are introduced both into the outer bearing elements and into the or each central sealing element in such a way that the slots run respectively next to one another and respectively one behind the other, in relation to the sandwich-like arrangement thereof, within the respective bearing element and within the respective sealing element. The strain relief elements are associated with at least one plate-like bearing element such that each data cable, which is sealed and is guided in the region of slots arranged one behind the other of the sandwich-like arrangement, can be restrained using a strain relief element.
摘要:
A thermoelectric module which has at least one thermoelectric element for converting energy between thermal energy and electrical energy. The at least one thermoelectric element has a first surface and a second surface opposite the first surface. The thermoelectric module further has a first electrode, the first electrode having at least a first region which is arranged directly on the first surface and a second electrode, the second electrode having at least a second region which is arranged directly on the second surface. At least one of the first region and the second region has a metal alloy which exhibits an Invar effect.
摘要:
The present invention relates to a drink which is an oil-in-water emulsion and which comprises hydrocolloids, where the hydrocolloids are a mixture of gellan and pectin, and where the oil phase or fat phase comprises sterols or stanols or fatty acid esters of sterols or fatty acid esters of stanols or a mixture of these substances. The hydrocolloids prevent or retard the settling of a precipitate of the oil phase or fat phase of the oil-in-water emulsion.

The invention relates to a squirrel-cage rotor for an asynchronous machine. In order to increase the electrical efficiency for a cage rotor composed of two materials, the cage rotor comprises a rotor core (1) having grooves (3), end rings (5) of a first material that are cast onto the rotor core on the end face, and conductors (4) that are arranged in the grooves and that are made of a second material that has an electric conductivity that is higher than the electric conductivity of the first material, wherein the conductors (4) comprise a coating (8) made of a coating material on the surface of the conductors, wherein the coating adjoins the second material of the conductors (4) by means of a first alloy layer (2) made of the second material and the coating material and adjoins the cast first material by means of a second alloy layer (9); made of the first material and the coating material.
摘要:
The invention relates to a cosmetic preparation that contains (a) at least one surfactant selected from anionic, zwitterionic or amphoteric surfactants, (b) a microemulsion and (c) at least one cationic polymer.
摘要:
The invention relates to the use of heterocyclic carboxylic acid derivatives of the formula (I) below in which the symbols have the meanings given in the description, or their agrochemically active salts or of mixtures of these compounds and/or their agrochemically active salts with other active compounds for controlling animal pests, to methods and compositions for controlling animal pests in and/or on plants or in and/or on seed of plants, to processes for preparing such compositions and treated seed.
摘要:
The invention relates to compounds of the formula (I) in which A1, A2, R1, R2, R3, R4, R5 and X are as defined in the description, to processes and intermediates for their preparation, and to their use for controlling pests.
摘要:
A process is provided for the preparation of a compound having the structure of Formula I The process includes reacting a heterocyclic amine with a monoaldehyde or a dialdehyde in a pH range of from about 8 to 14 and then quaternizing the so-reacted heterocyclic amine with an alkylating agent at a pH of not less than about 2. The use of pH control substantially prevents formation of an undesirable protonated reaction intermediate.
摘要:
An arrangement for securing a headlight or a lamp including a housing and a lens as a single unit on a vehicle part has several fastening elements which are not covered by the lens. A cover member provided to cover the fastening elements is designed so that a substantially homogeneous appearance is given the cover and the lens to a person observing the lamp.
