Patent DE-3146099-A1 (DE)
Title: Warning system for an automatic gearbox
Inventor: MOCHIDA HARUO
IPC: F16H59/10
Filed: 1981-11-20
Abstract: A warning system for an automatic gearbox comprises an alarm device and two or three control switches connected in series. One switch is closed when the speed range selector lever is not in the park position. The second switch is closed when a condition preceding the starting of the vehicle, such as, for example, opening of the door, is detected. The third, alternative switch is closed when an auxiliary brake is not correctly engaged. A warning signal is thereby produced when the driver prepares to leave the vehicle and the speed range selector switch is not in the park position. Redundant switches are indicated for the first and second switches. In addition a locking relay is proposed which maintains the warning signal by closing a switch bridging the second switch when the warning signal is generated until such time as the speed range selector lever of the automatic gearbox is shifted into the park position.

Patent DE-3215322-A1 (DE)
Title: Method and device for measuring the length of the material, guided in the form of a web, winding onto the winding beam of a winding machine
Inventor: SCHLOESSER HELMUT
IPC: G01B7/04
Filed: 1982-04-23
Abstract: During continuous winding operation, the length of the winding-on material (5) is determined with the aid of a gauge roll (7). The revolutions of the winding beam (2) are counted automatically at the same time in this case. The revolution counters (8, 9) that are present for this purpose are connected to an electronic evaluation device (13). The evaluation device (13) continuously makes use of the number of revolutions of the gauge roll (7) per revolution of the winding beam (2) automatically to determine and, if necessary, record, the circumferential length of the material (5) winding onto the winding beam. In the event of departure from continuous winding operation, the length of the material (5) winding onto the winding beam (2) is further counted in a way such that the last determined circumferential length is automatically summed per counted revolution of the winding beam (2) with the aid of special devices (15, 16) until the normal continuous winding operation resumes, whereupon the gauge roll (7) once again takes over the length measurement. The aim is as precise as possible a length measurement even in cases in which the gauge roll (7) cannot correctly fulfil its function. This is the case, for example, in acceleration processes, deceleration processes, startup processes or in creep-feed operation. <IMAGE>

Title: Process for continuously producing mouldings, preferably panels, from gypsum and fibrous material as well as an apparatus for carrying out such a process
IPC: C04B28/14
Filed: 1982-05-06
Abstract: In the case of a process for continuously producing fibrous gypsum panels, the mixture of gypsum and fibrous material is swirled without segregation while the water necessary for rehydration is added. The water is added, finely dispersed, to the mixture in the swirled state. Still before the setting process begins, the moistened mixture is spread out to form a mat and compacted. Due to the swirling of the mixed material, the water is ideally distributed, so that it can be fed in a precisely metered manner. In the case of the installation for carrying out the process, the water feed is arranged upstream from the spreading device and is directed in the direction of the effective range of the swirling device.

Title: Arrangement for the temporary maintenance of a DC voltage, derived from a mains voltage, in the event of mains failure
Inventor: MUHR JOHANN
IPC: H02J9/06
Filed: 1982-07-13
Abstract: The derived DC voltage which is dropped on the external resistor (R7) is obtained via a first transistor (T1) from a significantly higher operating DC voltage (UB1) at the input (E1, E2). At the same time, a first electrolytic capacitor (C1) is charged to approximately this operating DC voltage (UB1), and a second electrolytic capacitor (C2) is charged approximately to the base voltage of the first transistor (C1). If the operating DC voltage (UB1) fails, then the first electrolytic capacitor (C1) discharges via the first transistor (T1) and the external resistor (R7), while the charge of the second electrolytic capacitor (C2) maintains the base voltage on the transistor (T1). Because of the discharging of the electrolytic capacitors (C1, C2), the voltage on the output resistor (R7) falls slowly. If RAM modules are used instead of the external resistor (R7), the voltage falls, for example, so slowly that the store content is not lost for half an hour. <IMAGE>

Title: Circuit arrangement for pulsed driving of light-emitting diodes
Inventor: SCHWARZ GUENTER DIPL ING
IPC: G09G3/32
Filed: 1983-01-25
Abstract: Light-emitting diodes are frequently pulse-driven in order to increase the efficiency or for the purpose of multiplex operation. In this case, the steep edges of the current or voltage transitions produce high harmonic components having a corresponding disturbing effect. In order to suppress these disturbances, it is proposed to configure the voltage source, which emits the pulsed operating voltage in accordance with the driving control signal, in such a way that the switching edges which occur have a characteristic which is low in harmonics. A trapezoidal characteristic of the operating voltage is particularly simple and therefore advantageous.

Title: Rotary drums with compensation of the thermal expansions of the rotary drum casing in the region of the rotary drum mountings
Inventor: VITS REINHARD
IPC: F27B7/22
Filed: 1983-02-01
Abstract: To prevent or reduce stresses which arise in the casings of rotary drums, exposed to heat, due to the different thermal expansions of the rotary drum casing and the rotary drum mountings or their attachment structures, the radial thermal expansions of the rotary drum casing are compensated by the axial thermal expansions of the rotary drum casing. The compensation takes place in that the rotary drum is guided via attached blocks in a support structure for the mounting in the direction of a resultant of the radial and axial thermal expansion. It is ensured by this design that no, or only small, stresses arise in the rotary drum casing due to thermal expansion, the rotary drum casing, however, being connected, irrespective of its temperature and always free of play, to the rotary drum mounting.
