Patent EP-0095923-A3 (EP)
Title: Communications scrambling systems
IPC: H04K1/06
Filed: 1983-05-31
Abstract: Scrambled communications signalling uses signals as 
transmitted and received that are coded by reorganisation of 
binary words representing original information signals. That 
reorganisation not only produces different sequences of blocks 
of binary words but also provides for variation of the lengths 
and numbers of such blocks (via memori M100-M115) within 
each reorganisation. In addition the blocks are read out in 
reverse order to their storage, and the preferred organisation 
is via a logic type pseudo random generator that must be 
synchronised and «seeded» at both transmitter and receiver 
prior to any transmission.

der Rotor-Hubachse und des Flugzeugschwerpunktes. Als 
Fahrgestell kann der Pilot seine Beine benutzen, doch können 
auch abnehmbare Kufen bereitgestellt werden. Treibstoffbe­
hälter, Pilotensitz  und Geschirr sowie ein Heckrotor für Rich­

IPC: H01M50/583
Filed: 1986-11-27
Abstract: A special zener diode is disclosed which is shunted ac­
ross each cell in a series connected string of battery cells. In 
response to a cell failure which causes a cell to open circuit, 
all battery current is routed through the zener diode looping 
element. This current causes a permanent state change of the 
looping element thereby causing the looping element to be­
come a permanent short circuit. Thereby, the failed cell is 
effectively removed from the circuit. Another embodiment is 
disclosed whereby the zener diodes are used to ensure uni­
form full charge among all of the cells in the battery. The 
zener diodes are chosen to have a breakdown voltage slightly 
higher than the optimal maximum battery voltage. A special 
charger is used which lowers the charging rate when the 
zener breakdown voltage is approached, so that the zener will 
not be destroyed from excess current during charging.
