Title: Analogue-digital converter - has device for automatic zero correction, and comparator comparing input with reference signal
Inventor: FRANCK GUENTER DIPL-ING
IPC: H03K5/08
Filed: 1973-10-17
Abstract: Pulses are counted from the comparison start and they are counted up to equality of the two signals; the zero signal is periodically applied to the converter. A digital store stores the numbers counted by the counter, which correspond to the signal; when the zero signal is applied, the converted deviation from zero produces a counting result different from zero; in order to correct the deviation, the number stored in the store is returned to the counter and its reading is corrected; the converter input is short-circuited, a reversible counter is used, and its reading during the comparison process is applied to the store and used for the zero deviation correction; the counter counts forward during zero deviation detection.

Title: Excess heat protection for plug-in cigar lighter - has prestressed bimetallic spring snapping over to short circuit element
Inventor: SEIBEL GEORG
IPC: F23Q7/00
Filed: 1974-07-29
Abstract: The plug bearing the heater element is held in the socket against an ejector sprung by bimetallic springs which provide the contact with the heater element at the tip of the plug and expand to release the plug after it has heated up correctly. If the plug is held in after this point and overheats, the bimetallic protector snaps over and short circuits the heater, which causes the protection in the circuit to trip out. After cooling down the bimetallic protector springs back to its normal position and the heater is ready for reuse. The bimetallic protector preferably is a disc or web without ends and with its insulating disc forms one component with the heater element, being supported by a sleeve fitted to the plug.
