Title: Power failure detecting for sensing drop=out of AC mains voltage - using digital evaluation of frequency of mains voltage by passing through frequency multiplier, rectifier and monostable flip=flop to controller.
Inventor: DRAKE JOCHEN
IPC: G01R31/40
Filed: 1992-06-09
Abstract: The failure of the a.c. voltage is detected by digital evaluation of the frequency of the mains voltage.

Title: Switching-off carbon brush for motors with commutators, especially for a vacuum cleaner fan motor
Inventor: ESCH GUENTER
IPC: H01R39/59
Filed: 1993-02-15
Abstract: In the case of a switching-off carbon brush for electric motors, especially for a vacuum cleaner fan motor, which has a brush switching-off bolt which consists of insulating material, is arranged displaceably in a recess (which can be closed) in the carbon brush and is moved out by a compression spring when the carbon brush is worn out, the closure body for the recess is constructed as a clamping part which can be fitted externally onto the carbon brush.

Patent DE-4310031-A1 (DE)
Inventor: ZUMKELLER MARKUS DIPL ING
IPC: H04N7/14
Filed: 1993-03-27
Abstract: In the transmission of digital television signals using the COFDM method, the individual carrier frequencies used therein are phase-modulated. A phase reference signal is transmitted in each transmission frame in order to demodulate the individual carrier frequencies in the receiver. The phase difference between the phase reference signal and the individual carrier frequencies received in the same transmission frame contains the transmitted information. A problem lies in the phase and amplitude distortion of the individual carrier frequencies which can be caused by transmitter and receiver modules and by the transmission path. The novel method enables correction of these distortions, insofar as a mathematical model can be indicated therefor. To correct the phase of the received individual carrier frequencies, a mathematical model is built for the phase distortions of the phase reference signals dependent on time. The data signals received between two phase reference signals are corrected on the basis of this mathematical model of the temporal pattern of the reference phase. In order to eliminate additional random phase distortions, a maximum likelihood decision is made with the corrected phase value. The amplitude of the individual carrier frequencies is corrected using a standard amplitude value which is derived from the amplitudes of previously received individual carrier frequencies. The novel method enables the correction of phase-modulated individual carrier frequencies and can be used in transmissions based on the COFDM method. <IMAGE>

Title: Exhaust brake with gap opening position
Inventor: SCHMIDT ALFRED
IPC: F02D9/06
Filed: 1993-06-25
Abstract: An exhaust brake exists in which a throttle valve 2 is capable of swivelling to and fro between a closed position and an opened position and assumes a gap opening position shortly prior to the closed position. In this it is desirable to facilitate an assured gap opening position of the throttle valve and for it to be adjustable at reduced cost. This is achieved in that, with the throttle valve 2 situated in the gap opening position, the shaft 3 is fixed by means of a lever arm 15 on a stop 20 situated in the closed position which stop can be moved between the closed position and a release position by means of an additional piston-cylinder device 18, to which an additional compressed air device is connected. A driver of a vehicle provided with the said exhaust brake is assisted in warming up the engine of the vehicle at low engine speed with little throttle, producing very little white smoke. <IMAGE>
