Patent EP-0316203-A3 (EP)
Title: Protective relay
IPC: H02H3/38
Filed: 1988-11-11
Abstract: A protective relay for detecting faults within a 
predetermined protected zone of a three phase alternating 
current electrical power distribution system, of the type which 
utilizes at least one restraint signal in conjunction with at 
least one operate signal to generate a net operate signal, 
generates an operate quantity which is related to a zero 
sequence component of current flowing in the power distribution 
system and a second operate quantity which is related to a 
negative sequence component of the current flowing in the power 
distribution system. The operate quantities are summed to form 
an operate signal. An adaptive restraint, which is proportional 
to a negative sequence component of a phase voltage of the power 
distribution system, is generated and utilized to provide 
increased sensitivity to higher resistance ground faults. A 
portion of a positive sequence component of the current flowing 
in the power distribution signal is utilized as a restraint 
signal to prevent the unit from operating on negative sequence 
currents present during normal load conditions. Adaptive 
restraint enables the directional overcurrent unit to operate 
correctly should a second fault occur on the transmission line 
during the period that one pole is open.

Title: Barrette pour la connextion de deux circuits imprimés disposés perpendiculairement et son procédé de fabrication
IPC: H01R43/16
Filed: 1988-08-10
Abstract: Les éléments conducteurs 1 à décrochement 1a et 1′ sont pourvus 
respectivement de pointes 3 et 4 et 3′ et 4′ disposés de manière 
perpendiculaire afin de pénétrer respectivement dans les perfo­
rations correspondantes pratiquées dans l'un et l'autre des 
circuits disposés perpendiculairement. Ces éléments 1 et 1′ sont 
rendus solidaires sur le plan mécanique par surmoulage d'un 
matériau isolant formant support 2. Une saillie 5 en forme de bec 
noyée dans le support 2 interdit toute libération ultérieure des 
éléments 1 et 1′.  
     On peut obtenir industriellement ces barrettes en disposant en 
alternance parallèlement et à l'écartement requis une pluralité 
de chaínes constituées chacune respectivement d'éléments conduc­
teurs de type 1 et 1′ à la suite les uns des autres,en opposition 
symétrique par les pointes par paires, et en présentant le dit 
ensemble à la machine effectuant le surmoulage 2, de manière à 
déterminer une grille qui l'on peut ensuite tronçonner aux 
points d'attache de deux éléments conducteurs voisins.

Patent EP-0332095-A3 (EP)
Title: A switch-mode power supply
IPC: H02M3/335
Filed: 1989-03-04
Abstract: An input supply voltage is coupled via a primary 
winding of a flyback transformer to a collector of a 
chopper transistor switch that operates at a given 
frequency. During a portion of each period when the chopper 
transistor switch is conductive, a second switch applies a 
short-circuit across a secondary winding of the transformer 
at a controllable instant that causes the emitter current 
of the chopper transistor switch to increase at a 
significantly higher rate. When the emitter current 
exceeds a predetermined threshold level, a one-shot 
arrangement is triggered. Consequently, a pulse is 
produced that turns off the chopper transistor switch and 
that maintains it nonconductive for the duration of the 
pulse. A flyback pulse produced in a winding of the 
transformer is rectified to produce a DC output supply 
voltage. The length of the interval when the chopper 
transistor switch is conductive is controlled by the second 
switch in accordance with the level of the output supply 
voltage in a negative feedback manner for regulating the 
output supply voltage.

Title: Reactor and method for the production of carbon black with high surface activity
IPC: C09C1/48
Filed: 1989-06-02
Abstract: An axial flow carbon black reactor produces carbon 
black with a high surface activity. The exit chamber has a 
diameter which gradually increases towards the exit opening 
of the reactor so that the flow of hot gas and pyrolyzing 
feedstock hydrocarbon is a substantially plug flow through 
the exit chamber. This provides for a substantially uniform 
residence time and a reduced average residence time of the 
pyrolyzing feedstock hydrocarbon in the reactor. 
Accordingly, the feedstock hydrocarbon is not 
overpyrolyzed and the surface activity of the forming carbon 
black particles is preserved.
