Patent EP-0255326-A3 (EP)
IPC: H02M3/335
Filed: 1987-07-28
Abstract: A switching converter in which current mode voltage regulation is 
implemented includes circuitry to add ramp compensation to the sensed current 
signal at light load and reduce or disable this ramp signal compensation at 
heavy load 257, 258, 259, 260. This load dependent ramp signal improves the 
stability of the converter and maintains its inherent current limit performace

Patent EP-0287735-A3 (EP)
IPC: E21B17/00
Filed: 1987-11-03
Abstract: A method for completing a drainhole wellbore with 
casing but without conventional cementing of the casing where­
in in the drainhole portion of the wellbore a casing string 
composed of alternating casing subs and external casing packer 
subs is employed, the external casing packer subs carrying an 
elastic member adapted to be expanded and form a seal between 
the exterior of the casing string and the wellbore wall, and 
one or more of the external casing packer subs is activated 
to expand the elastic member carried by same thereby providing 
for isolation of discreet segments of the casing string in the 
drainhole portion of the wellbore to allow for localized pro­
duction and remedial treatments in the drainhole wellbore.

Patent EP-0381802-A3 (EP)
Title: Wireline transmission method and apparatus
IPC: E21B47/12
Filed: 1989-03-10
Abstract: In a wireline data transmission system for 
passing data between downhole and surface locations in a 
wellbore, a system for transmitting data at a frequency 
above the relatively low roll off frequency of a wireline 
permits higher data rates to be transmitted over the 
wireline than would be possible using standard digital 
data formats. The present system utilizes short duration 
pulses which are placed on the wireline in conformity to 
the transition edge between voltage levels in a typical 
digital data format, and thus transmits the digital data 
over the wireline in a manner which is not adversely 
affected by the phase shifting which normally occurs when 
bi-level voltage data formats are used for data 
transmission over a wireline. The short duration pulses 
are placed on the wireline at a time position in a data 
format that corresponds to the beginning of a bit period 
and the pulse width is such that it only occupies a 
fraction of the bit period so that any phase shifting on 
the pulse does not shift the pulse into a succeeding bit 
period to thereby adversely affect data interpretation.
