Patent DE-4236646-A1 (DE)
Inventor: HERBURG ANDREAS
IPC: A24C5/20
Filed: 1992-10-30
Abstract: The invention relates to a device for feeding a wrapping strip (11a, 11b), in a tow machine in the tobacco processing industry, for a tow (4a, 4b) which may consist of smokable material or filter material, and is conveyed by a tow conveyor belt (3a, 3b). The problem underlying the invention comprises ensuring reliable entrainment of the start of the wrapping strip to the garniture of the machine, in which the tow is wrapped with the wrapping strip. According to the invention, the problem is solved in that a displacement element (21a, 21b) is provided which can be activated, when the start of the wrapping strip is fed, to reduce the distance between the tow conveyor belt and the wrapping strip. As a result of the invention, simple threading of wrapping strips and reliable entrainment of the start of the wrapping strip are guaranteed. <IMAGE>

Title: Method and arrangement for supplying a measurement laser with power, in particular a diode laser for absorption-spectroscopic trace-gas analysis
Inventor: WERLE PETER DR
IPC: G01N21/39
Filed: 1993-06-17
Abstract: The invention relates to a method and arrangement for supplying a measurement laser with power, in particular a diode laser for absorption-spectroscopic trace-gas analysis. According to the invention, a diode-laser power supply output stage having an extremely small bandwidth is used, full electrical isolation between the DC diode-laser power supply and a tuning signal optically implemented in the diode laser being provided. By virtue of the small bandwidth of the laser power supply, which no longer depends on the frequency of the signal required for tuning, interferences which otherwise reach the diode laser via the power supply can be efficiently suppressed, which makes possible more stable operation of the laser, which is a prerequisite for high sensitivity in correspondingly equipped measurement systems. In order to avoid a phase shift between the optical signal for tuning the diode laser and the frequency alteration of the latter produced thereby, thermo-optical imaging or the supply of a defined quantity of heat, starting from a tuning laser, directly into the region of the pn junction of the measurement or diode laser takes place.

Title: Method for controlling and regulating an air-conditioning system or automatic air-conditioning unit for motor vehicles
Inventor: BUSCH LOTHAR
IPC: B60H1/00
Filed: 1993-10-30
Abstract: The invention relates to a method for controlling and regulating an air-conditioning system or automatic air-conditioning unit for motor vehicles with a control unit with a first and a second temperature-setting element for manual input of the desired value of the temperatures to be set for the left-hand side and right-hand side of the vehicle interior, and with setting elements which are provided jointly for both parts of the vehicle interior and are intended for uniform distribution of air to both sides of the vehicle interior, one setting element being provided for switching on automatic operation in which the distribution of air to both sides of the vehicle interior is regulated uniformly, i.e. in one duct. In this method, even when automatic operation has been switched on and the distribution of air is thus regulated through one duct the regulation of temperature for both sides of the vehicle interior takes place separately and hence through two ducts. In order, in this arrangement, to obtain a comfortable climate for the interior of the vehicle, in automatic operation the defroster flaps are controlled as a function of the desired temperature value for the driver's side, or alternatively as a function of the higher of the two desired temperature values, the ventilation flaps are controlled as a function of the higher of the two desired temperature values and the leg-room flaps are controlled as a function of the lower of the two desired temperature values.
