Abstract:
An apparatus for filling a prefabricated cigarette tube includes a housing, a tobacco chamber with a tobacco holder, and a movable pressing bar configured so as to form tobacco introduced into the tobacco chamber into a tobacco strand. An abutment for an end of the tobacco strand is assigned to the tobacco holder, wherein a first length of the to be formed tobacco strand is adjustable to prefrabicated cigarette tubes having different filling-cavity lengths by adjusting a second length of the pressing bar. A slider is configured to be moved relative to the housing so as to fill the prefabricated cigarette tube with the tobacco strand. The tobacco holder is displacably arranged relative to the abutment in a movement direction of the slider by a distance which approximately corresponds to the different filling-cavity lengths.
Abstract:
The invention relates to a process for preparing an alcoholic solution of an alkali metal alkoxide from alkali metal hydroxide and alcohol in a reaction column, the alcohol and the alkali metal hydroxide being conducted in countercurrent, which is characterized in that a reflux ratio of at least 0.05 is established in the reaction column.
Abstract:
A device for controlling the reflection of incident beams to influence navigation of an autonomous device having a navigation sensor comprising a beam emitter and a beam detector for detecting reflected emitted beams. The device comprises at least one surface having a geometry configured to direct a reflection from the emitted beam in a predetermined direction so that a suitable amount of the reflected beam can be detected by the detector.
Abstract:
A method and a device for the playback of digitalized audio signals that are transmitted packet-oriented from a signal source to at least one signal sink, especially a loudspeaker unit, in a motor vehicle by means of an asynchronous bus system. Connected upstream of the signal sink is an audio-signal processing unit demonstrating a data rate converter, which is fed the digitalized audio signals destined for the signal sink from a control unit over a data line by means of a first data interface of the control unit. The control unit has a second data interface for the connection to the asynchronous bus system and for receiving the digitalized audio signals. A data buffer and a controller are arranged within the control unit. A first and second clocking signal provide the clock rates for the first interface and the data rate converter. These clock rates can be changed by a logic unit.

Abstract:
An electron beam line evaporator for coating heat-sensitive strips or substrates includes a magnetic trap overlying an evaporation crucible to prevent unpermissible heating and static electrification by back-scattered electrons, complemented with means to influence the injection angle of a dynamically deflected electron beam in such a manner that the beam enters the horizontal magnetic field of the trap at the same angle in each deflection phase independent of stray fields. Such means are arranged inside a gap of a pole shoe necessary for the horizontal magnetic field used by the trap and are operative to generate a vertical magnetic field variable in time and locally alongside the pole shoe.
