The invention relates to a method and to a system for producing a filled consumable product, in particular a shell-like consumable product consisting of at least two different substances which form the covering and/or shell of the consumable product and the second filling the consumable product. Said method comprises the following steps: a) a covering, which comprises an opening, is produced; b) a filling is added to the covering via an opening; and c) a cover is applied to the opening in order to close the filled covering. The filling is added according to step b) and the cover is applied according to step c) which takes place simultaneously in one step. Means for adding the filling and means for applying the cover can be displaced together and at a constant distance according to the inventive system.

Processes comprising: (a) reacting phosgene and a monohydroxyl aryl compound in the presence of a suitable catalyst to form a diaryl carbonate and a solution comprising an alkali chloride; (b) separating the diaryl carbonate from the solution; (c) adjusting the pH of the solution to a value of less than or equal to 8 to form a pH-adjusted solution; (d) treating the pH-adjusted solution with an adsorbent to form a treated solution; (e) subjecting at least a portion of the treated solution to electrochemical oxidation to form chlorine and an alkali hydroxide solution; and (f) recycling at least a portion of one or both of the chlorine and the alkali hydroxide solution.
摘要:
A shelf for electronic plug-in units is provided. The shelf includes at least one support plate that has at least one shaped opening. At least one guide rail is arranged for being mounted on the support plate, which includes a guide groove for receiving the electronic plug-in unit. There is also provided at least one positioning unit arranged on the guide rail, which includes a trunnion insertable form-fittingly into the shaped opening in the support plate to fix a position of the positioning unit relative to the support plate, and a locking element to lock in place an electronic plug-in unit fully inserted into the guide rail.

The invention relates to a method for producing chlorosilanes using silicon containing homogeneously distributed copper silicide. The invention especially relates to a method for producing trichlorosilane by reacting said silicon with water, silicon tetrachloride and optionally hydrogen chloride.
摘要:
A pair of spectacles has lenses (1, 2) that are connected to one another by a bridge element (3). The sides (6) are connected to the lenses (1, 2) by holding elements (5). The holding elements (5) and the bridge element (3) are preferably produced from flexible wire. The bridge element (3) and the holding elements (5) are connected to the two lenses (1, 2) by corresponding angled portions. A holding portion and a pin portion connect with the lenses (1, 2). The pin portion is accommodated in a through-bore of the lenses (1, 2). The holding portion is accommodated in a respective slot of the lens. Variations are possible by providing a simple plug-in connection allowing a selection to be made from a modular system, which enables the purchaser to assemble his/her own individual pair of spectacles.
摘要:
An inventive device (1) for cordless telephones (4), with which a base station (2) and at least one charging station (3) are associated in order to charge a battery of a cordless telephone (4) via the charging station (3) when the cordless telephone (4) is located in the charging station (3), is characterized by a mechanical connecting device (10, 11, 14, 17) for detachably connecting the charging station (3) and base station (2) to one another. As a result, more flexible possibilities of use for the charging station (3) are obtained.
