Abstract: The invention relates to flame-retardant polyurethane foam materials or polyurethane/polyisocyanurate foam materials (also referred to individually or collectively as “PUR/PIR foam materials” below) and to methods for producing PUR/PIR foam materials by reacting a reaction mixture containing A1 an isocyanate-reactive component, A2 a propellant, A3 a catalyst, A4 optionally an additive, and A5 a flame retardant with B an isocyanate component, wherein the production is carried out using an index of 80 to 600. The invention is characterized in that the flame retardant A5 contains (hydroxymethyl)phosphonate and optionally the dimer thereof as component A5.1.

Abstract: The invention relates to a multi-compartment packaging comprising a base part provided with at least two cups (11,12) which are used to receive the components, and a cover film which is connected to the base part. The components can be mixed together by exerting pressure on the connection area between the at least two cups which, as a result, becomes detached. The cover film is made of at least two films (20,30) having different structures. One section or one surface arranged above at least one cup (11) is covered by only one of the two films (20). Due to said selective covering of the base part and/or the components located in the two cups by the films adapted to the user profile of the compartments, the desired physical properties can be adjusted in a separate manner in relation to the density and/or light-impermability for the two cups.

Abstract: The invention relates to a sensor arrangement for seat occupation detection, comprising a fiber-optic sensor network consisting of at least two sensors. The sensor network detest for example local damping modifications in a fiber network that are caused by microbends or modifications of the Bragg wavelength of fiber-optic Bragg grating sensors (FBGS) distributed in the fiber network that are ceased by loads. The optical sensor network is resistant to electromagnetic parasitic inductions. Due to the nature of the optical lass or polymer optical fibers it is for example possible to integrate the network into the textile cover of the seat or into a cushion.

Abstract: The invention relates to an optical signal transmission system for transmitting data between electronic units via a rear plate. The inventive transmission system comprises a point of separation on which an optical image system (31), for an easily separable connection, is arranged in such a way that optical power loss during the signal transmission is minimised.

Abstract: The invention concerns an opto-electronic connector system with a plug 1 and a receptacle 2. The plug 1 includes a tube shaped housing 3 with an area for introduction or output of an optical signal as well as at least one opto-electronic and/or electro-optical transformer 8a, 8b and a therewith associated optical element 7 for beam guidance. Beyond this, electrical contacts 10 for input or output of an electrical signal are provided, which are connected with the one or more transformers (8a, 8b) via amplifier stage 9a, 9b. The tube shaped housing 3 is preferably in the form a cylinder or truncated cone, which engages in a corresponding recess 4 in the receptacle 2 when in the connected condition. The receptacle 2 is adapted for integration on a circuit board. The opto-electronic connector system has been found to be particularly small in its external dimensions.

Abstract: A perfume tester comprises a test strip made of an absorbent material that is wetted with perfume. An end area of the test strip (3) is fixed inside a pouch (1) made of plastic films (1.1, 1.2). Above this end area, the pouch (1) comprises a specified rupture line (6), which extends over the width of the pouch and which tears along the longitudinal axis of the test strip (3) when the ends (4.5) of the pouch (1) are subjected to tensile stress thereby exposing a significant portion of the test strip (3). The inventive perfume tester can be easily produced and is well-suited for all channels of distribution. The impregnated test strip is protected against direct finger contact thereby enabling several successive smelling tests to be carried out without the test strip becoming adulterated.

Abstract: A connecting housing for optical transmission lines, consisting of an upper and a lower housing part, which are joined in the manner of a snap fastener. Once the housing is connected, a free beam distance appears between the optical transmission lines, in which optical elements are arranged for focussing and/or deflecting the light beam.

Abstract: A container to hold aromatic substances which can be sealed aroma-tight with a composite film consisting of several laminae. The composite film on the top of the container is made up of an aroma-tight outer film having at least two laminae and an aroma-permeable inner film which is detachably bonded to the outer film by means of a bonding agent. The outer film can be applied onto the inner film or membrane film, which consists of at least two permanently bonded laminae, whereby the lamina adhering to the container is made of polyethylene and the third or top lamina is made of a polymer materialwhich has a different density. The surface structure of the side of the membrane film facing away from the container is selected in such away that the entire membrane film stays on the container when the outer film (16) is pulled off.

Abstract: The present invention relates to an economically manufactured monomode quartz glass light waveguide and to a method for producing it, particularly for the spectral range around 1.3 .mu.m and around 1.56 .mu.m, with optical transmission losses less than 0.5 dB/km. This is accomplished by a light carrying core region surrounded by inner and outer (quartz glass) jacket regions. The outer diameters of the inner jacket region and of the core region have a ratio which lies in a value range from about 1.8 to about 3.5.

Abstract: An optical copying arrangement, particularly an electrostatic copying arrangement, has a carriage provided with a transparent supporting plate for an original and movable in a substantially horizontal direction, a drive for moving an image carrier onto which an image is to be copied from the original, and a scanning system arranged to scan the original supported on the supporting plate by successive strips and form a copy on the image carrier, wherein the supporting plate has a part which in initial position of the carriage is located prior to a first strip, considered in direction of carriage movement, and is bent downwardly relative to the main part of the supporting plate.

Abstract: An electrostatic copying device comprises a transparent support plate onto which an original to be copied is placed. A slide carrying a recording cylinder provided on its peripheral surface with a photosensitive layer is movable beneath and parallel to the transparent support plate. At least one gear coaxially fixed to the recording cylinder meshes with a rack extending parallel to the path of movement of the slide to rotate the recording cylinder during movement of the slide. The slide carries also a raster objective stepwise scanning the original during movement of the slide to produce a latent image of the original on the photosensitive peripheral surface of the recording cylinder, which picture is transferred to an endless dielectric band forming an intermediate recording carrier and from the latter the picture is transferred to a photosensitive paper sheet fed onto the band along which also a plurality of usual treating stations are arranged for developing the image on the paper sheet.

Abstract: The remnants of film units which are withdrawn from a cassette in the housing of a camera for instant photography are reintroduced into the cassette subsequent to development of images and separation of image-bearing sheets. The reintroduction can be effected by a manually operated yoke, by the pressure applying rolls which serve to spread a fluid processing agent between the positive and negative sheets of an exposed film unit, by an additional roll in cooperation with one of the pressure applying rolls, or by a separate set of advancing rolls.
