Patent EP-0389904-A3 (EP)
Title: Semi-conducting oligomers and method relating thereto
IPC: C08G61/12
Filed: 1990-03-17
Abstract: The present invention relates to a number of innovative 
electrophilic substitution reactions involving 2,5-dithienylpyrrole 
(2,5-DTP). More specifically, these reactions are used in the 
synthesis of monomers for preparing functionalized conducting organic 
polymers.  
     The electrophilic substitution reactions in this 
invention are accomplished under conditions not requiring the use of 
N-1 pyrrole blocking groups to direct reaction at the pyrrole C-3 
position. This is because the steric bulk of the 2,5-dithienyl groups 
prevent N-acylation and therefore direct reactions with electrophiles 
at the pyrrole C-3 position.  
     The reaction conditions chosen have 
also demonstrated a greater regioselectivity towards functionalization 
at the pyrrole 3-position that the basic reaction conditions suggested 
in the prior art. This result may be explained by an activation of the 
pyrrole 3-position towards electrophilic substitution. This is 
attributed to an electron donating resonance contribution of the 2,5 
thienyl groups.  
     Other advantageous reaction conditions have been 
discovered which direct electrophilic substitution preferentially at 
the pyrrole or thiophene groups depending upon the amount of acidic 
catalyst.

IPC: G07F7/08
Filed: 1990-06-06
Abstract: A credit card system comprises a central unit 
and plurality of local units communicating with the 
central unit. The central unit includes a central 
storage device for each subscriber for storing amounts 
to be charged to the respective subscribers, and each 
of the local units includes a plurality of local 
storage devices assignable to the subscribers, at least 
one card reader for receiving a subscriber's card and 
for enabling the subscriber to open a local account, to 
transfer thereto a predetermined sum from the central 
unit, and thereafter to order local transactions 
involving the sale of products or services from the 
local account, until a specified permitted sum is in 
the local account. When the local account drops below 
the permitted sum, a transfer is automatically effected 
from the subscriber's central storage device. The 
system thus performs both local and central 
transactions while minimizing communication with the 
central unit, thereby enabling credit card transactions 
of low value, and at high-speed.

Title: Partial elimination of copper plate from steel strip by mechanical means
IPC: B23K35/38
Filed: 1991-10-11
Abstract: A process for producing non-corrosive double-wall tubing in which an unbrazed, unsealed continuous double-wall tube of a given circumference is formed from a metal sheet composed of a first non-ferritic metal having a first defined region of exposed non-ferritic metal and a second region of a second metal in overlying relationship thereto, said exposed region having a width essentially equal to the circumference of the finished tube. The process including the steps of elevating the surface of the stainless steel to a brazing temperature while maintaining the material in a humidified gaseous atmosphere consisting essentially of a non-reactive carrier gas and a reactive gas present in sufficient concentrations to achieve fluxing; maintaining the surface temperature of the steel for an interval sufficient to permit fusion between the selected metal and the non-ferritic steel surface; after metal fusion has been achieved, allowing the resulting fused metal material to cool to a first lowered temperature in a controlled non-oxidative atmosphere at a rate which retards the formation of fine-grained steel crystals in the metal; and after reaching a metallurgical transformation point, rapidly cooling the fused metal in a controlled atmosphere to a temperature below which the brazing metal is not reactive with oxygen. This process can be employed successfully in manufacturing unique, double-wall tubing which is relatively flexible and highly corrosion resistant.

Patent EP-0715863-A3 (EP)
Title: Catheter
Inventor: SAMSON GENE
IPC: A61M25/16
Filed: 1995-11-10
Abstract: This invention is a surgical device. In particular, it is a catheter suitable for accessing a tissue target within the body, typically a target which is accessible through the vascular system. Central to the invention is the use of a stiffener ribbon, typically metallic, wound within the catheter body in such a way as to create a catheter having controllable stiffness. The stiffener ribbon is adhesively bonded to a flexible outer tubing member so to produce a thin wall catheter section which is exceptionally flexible but highly kink resistant. The catheter sections made according to this invention may be used in conjunction with other catheter sections either using the concepts shown herein or made in other ways. Because of the effective strength and ability to retain a generally kink-free form, these catheters may be effectively used in sizes which are quite fine, e.g., 0.015'' to 0.020'' in diameter, and usable within typical vascular catheters. <IMAGE>

when neither the I nor the Q component is at least the desired voltage. A counter
may buffer the accumulator changes.

Abstract: An engine power system (10, 30, 34) that includes an internal combustion
engine (12), a plurality of power components (16, 18, 20, 38) each having a rotary input, a
drive shaft (22) interconnecting the rotary inputs of the several components, and facility (24,

Filed: 1997-01-27
Abstract: A frequency-to-current converter (10) includes several
capacitances with capacitive values that are
effectively multiplied. After each of a series of
periodic pulses, the voltage on a "ramp" capacitance (C ramp ) is
charged to a starting voltage (V start ). Then, during the
period preceding the subsequent pulse, the ramp capacitance is
allowed to discharge at a discharge rate that is a
function of a voltage (VCCB) on a discharge-current bias
capacitance (CCB). At the end of the period, the voltage on
the ramp capacitance is sampled and compared to a reference
(V fixed ). If the voltage (V ramp ) on the ramp
capacitance (C ramp ) is
too low or too high, indicating a discharge current
that is too high or too low, respectively, the bias
voltage (VCCB) on the bias capacitance (CCB) is adjusted to
compensate for the error. In another embodiment, a
small ramp capacitance is repetitively charged and
discharged between two reference voltage levels using
alternating charge and discharge current levels. The
charge and discharge current levels are related to
output current levels so that the rate at which the
ramp capacitance transitions between the two reference
voltages provides an indication of the output current.
