摘要:
A gas mask is provided with a mask body, which is designed to cover the face of a user, and with an opening in the mask body, which is closed by a speech diaphragm (8) in a gas-tight manner. A funnel (4) is directed toward the speech diaphragm with an opening angle in the range of 20° to 90°. The funnel (4) is arranged in front of the speech diaphragm in the interior space of the mask body in order to focus sound waves onto the speech diaphragm.

The present invention relates to five-layered pigments based on multicoated platelet-shaped substrates which comprise a layer sequence comprising (A) a layer of SnO2 having a layer thickness of 0.1-50 nm, (B) a high-refractive-index coating consisting of TiO2 in the rutile modification having a layer thickness of 10-800 nm, (C) a colorless coating having a refractive index n≦1.8 having a layer thickness of 20-800 nm, (D) a high-refractive-index coating consisting of SnO2 having a layer thickness of 0.1-50 nm, (E) a layer of TiO2 in the rutile modification having a layer thickness of 10-800 nm, and optionally (F) an outer protective layer, and to the use thereof in paints, coatings, powder coatings, printing inks, security printing inks, plastics, ceramic materials, glasses, as dopants for the laser marking of papers and plastics, in cosmetic formulations and for the preparation of pigment preparations and dry preparations.
摘要:
A modular testing plant comprising at least two building modules which are designed as transportable containers and which each have two side walls and two transverse walls connecting the side walls, wherein at least one building module having a length L2 and a width B2 and designed as a first testing module for receiving a test item is provided, and at least one building module having a length L4 and a width B4 and designed as a first supply module for receiving supply technology is provided, wherein the first supply module is arranged above the first testing module and the length L4 is less than the length L2. To complete the testing plant, at least a third building module designed as a first testing technology module for receiving testing technology is provided, wherein the first testing technology module has two side walls, two transverse walls connecting the side walls, a length L3 and a width B3, wherein the first testing technology module can be placed, in respect of the side wall, laterally next to the first testing module against the side wall, and the width B4 is at least 20% less than the width B2 or B3, which means that the ratio of B4/B2 or the ratio of B4/B3 is at most 2/2.5.
摘要:
A system for predictive front lighting of a vehicle. The system includes a first and second headlamps, a first and second swivel mechanisms and a controller. The first and second headlamps project a beam pattern for illumination of the vehicle path. The controller receives vehicle position data, for example from a GPS system, and accesses a map database to identify a map location of the vehicle. The controller further analyzes the map to determine a most likely path of the vehicle based on the map location and other vehicle heading parameters. The controller then calculates the desired swivel angle of the first and second headlamps based on the most likely path of the vehicle, and the first and second swivel mechanisms manipulate the first and second headlamps to accordingly change the swivel angle of the headlamps.
摘要:
Multilayer interference pigment consisting of a transparent carrier material coated with alternating layers of metal oxides of low and high refractive index, the difference in the refractive indices being at least 0.1, which is obtainable by alternate coating of the transparent carrier material with a metal oxide of high refractive index and with a metal oxide of low refractive index in a wet process by hydrolysis of the corresponding water-soluble metal compounds, separation, drying and, if desired, calcination of the resulting pigment.
摘要:
An optical safety edge and control system functions correctly despite changes in ambient conditions and/or deformation of the sensor. The optical safety edge and control system automatically compensates for changes in ambient conditions and/or deformation, thus providing a simple easy to use edge sensor which reduces false responses and system failures.
