Abstract:
The invention proposes a dielectric barrier discharge lamp having a phosphor mixture and improved color rendering. The phosphor mixture comprises at least the phosphor components A: cerium-activated yttrium aluminate (Y3Al5O12:Ce) and B: europium-activated barium magnesium aluminate (BaMgAl10O17:Eu). To further improve the color rendering and to match the emission spectrum to the spectral sensitivity of film, the phosphor mixture optionally also comprises the phosphor component C: cerium- and manganese-activated gadolinium magnesium zinc pentaborate (Gd(Zn,Mg)B5O10:(Ce, Mn)) and/or the phosphor component D: europium-activated strontium aluminate (Sr4Al14O25:Eu).

Abstract:
The present invention relates to a method for controlling a user terminal of a communications network, the user terminal having a communications unit, a subscriber identification means including a restricted using mode list, each entry of which includes an identifier (AI) and/or ID-number of a communications link and/or a class of communications links which are allowed when a restricted using mode of the user terminal is enabled, and memory means for storing entries including identifiers and associated ID-numbers of communications links. The inventive method comprises: inputting a request for a communications link (S10) and building-up requested communications links (S50), if the restricted using mode is not enabled (S20); otherwise comparing the ID-number of the requested communications link with entries of the restricted using mode list (S40) and building-up the requested communications link (S50), if the ID-number matches an entry of the restricted using mode list; otherwise rejecting the request (S45).
Abstract:
In a process for concentrating an at least partially crystalline solid containing at least one zeolite in a mixture comprising at least one auxiliary, for example a template compound, and said solid, the mixture is ultrafiltrated in a step (II) to divide the mixture into a retentate and a permeate, the solids content in the retentate being higher than that in the mixture and the solids content in the permeate being lower than that in the mixture. This procedure allows auxiliaries, in particular template compounds, present in the permeate to be recycled into a crystallizing step (I) upstream of step (II).
Abstract:
A process for the regeneration of a zeolite catalyst which comprises treating the catalyst thermally in the presence of a gas stream at temperatures above 120° C., the weight-based residence time of the gas stream over the catalyst during the thermal treatment being greater than 2 hours.
Abstract:
In a process for preparing N-phosphonomethylglycine or a salt thereof by bringing phosphonomethyliminodiacetic acid or a salt thereof into contact with at least one oxygen-containing oxidant in the presence of a heterogeneous catalyst, the heterogeneous catalyst comprises at least one silicate.
Abstract:
Process for the preparation of a crystalline solid comprising at least one zeolitic material, in which the solid is crystallized from at least one precursor compound and the reaction discharge of the crystallization is fed directly to a drying stage.
Abstract:
A process for preparing glycol monoethers from olefins comprises reacting the olefins with an epoxidizing reagent in the simultaneous presence of hydroxyl-containing organic compounds over a mixture of epoxidation catalysts and alkoxylation catalysts.
Abstract:
In a combined mechanical and electronic key, electronic components and mechanical flat keys (30) are normally housed in a common key holder (10). In order to place the flat key (30) between a lowered rest position in a holder (10) and a projecting in-use position, the flat key (30) is movably located in a container (10) and secured in at least one of the positions by a push button (40). The key contain is assembled from an upper and a lower shell. In order to avoid sealing problems between both shells, according to the invention, the upper shell (11) is provided with an outbreak in a region pertaining thereto which lies outwith the push button. The outbreak creates a void chamber which can be accessed from the outside and is located on the inside of the shell interior. The electronic components are enclosed by a housing-like capsule and form therewith a prefabricated electrocapsule (20). The electrocapsule (20) forms a socket unit, which can be inserted thereafter in the void chamber pertaining to the pre-assembled key container (10). The electrocapsules (10) are secured in the key container (10) when inserted in the socket. The push button (40) is used to advantage for securing.
Abstract:
A polyalkylene carbonate, an alternating copolymer, may be prepared by the ring opening of an alkene oxide or an alkene oxide precursor in the presence of carbon dioxide or any substance delivering carbon oxide, in the presence of at least one catalyst comprising a metal-organic framework material, wherein said framework material comprises pores and a metal ion and an at least bidentate organic compound, said bidentate organic compound being coordinately bound to the metal ion.
Abstract:
Cycloalcanoindole and -azaindole derivatives are prepared by reaction of appropriately substituted carboxylic acids with anmines. The cycloahloanindole and -azaindole derivatives are suitable as active compounds for medicaments, preferably antiatherosclerotic medicaments.
