Patent EP-0307532-A3 (EP)
Title: Fuel pressure regulator
IPC: F02M69/54
Filed: 1988-01-29
Abstract: A fuel pressure regulator comprising a housing (10), a 
diaphragm (15) dividing the housing into a first chamber 
(16) and second chamber (17), a passage (22) into a first 
chamber (16), an inlet (23) and an outlet (24) to the 
second chamber (17) and a valve seat (26). A carrier (19) 
is mounted on the diaphragm (15) and is urged by a first 
spring (21) toward the valve seat (26). The carrier (19) 
supports a plate (28) that has an opening (29) therein. A 
valve (30) has a hollow tubular closed end portion (31) 
that projects through the opening (29) in the plate (28) for 
engagement with the valve seat (26) and a peripheral portion 
(32) that retains the valve (30) between the carrier (19) 
and the plate (28). A second spring (33) is interposed 
between the carrier (19) and extends into the tubular portion 
(31) of the valve to yieldingly urge the valve (30) toward 
the valve seat (26) and permit relative movement there­
between. The opening (29) of the plate (28) is larger than 
the tubular portion (31) of the valve and the valve (30) is 
movable transversely to provide for proper centering of 
the valve in the valve seat (26).

Patent EP-0274427-A3 (EP)
IPC: G06V10/40
Filed: 1988-01-06
Abstract: Raw feature sensors (110) are arranged in rank 
order for sensing raw features which exceed a 
respective set of raw feature values. Each raw 
feature sensor (110) determines if a feature exists 
which falls within its range. The raw feature 
sensors have ranges which are exponentially separated 
by a constant factor, which may be chosen to allow 
easy approximate calculation of small integer ratios 
or other important ratios. A contrast enhancer may 
be used in the case of visual data to improve the 
operation of the raw feature sensors. A 
ratio-detector network is responsive to the raw 
feature sensors and calculates ratios of the raw 
feature data. The ratio-detector network pairwise 
ANDs each possible pair of results from the raw 
feature sensors and combines these pairwise AND 
results with OR gates to generate a set of outputs, 
each of which indicates the detection of a single 
ratio.
Patent EP-0279592-A3 (EP)
IPC: H01H50/00
Filed: 1988-02-12
Abstract: An electromagnetic contactor or motor controller 
(10) in which an energy efficient bounceless contact 
closing operation is utilized. The energy supplied to the 
armature (40) of the electromagnetic closing coil (31) is 
such that the armature attains a predetermined velocity 
during its closing operation which predetermined velocity 
is approximately sufficient to allow the armature to move 
to its final fixed closed disposition where the air gap 
(58) between it and a permanent magnet (86) is reduced to 
zero at a velocity of approximately zero. One field of use 
is in the motor starters. An advantage lies in the fact 
that the present system reduces the required contact 
closing energy to a minimal amount.

Patent EP-0306330-A3 (EP)
Title: Toner and process for preparation thereof
IPC: G03G9/08
Filed: 1988-09-02
Abstract: Toner particles are described, each particle comprising a spheroidal 
resin core, a pigment layer on the surface of said core and a layer of a 
static electrification controlled resin on the surface of said pigment layer. 
The state of static electrification of the toner is substantially deter­
mined by that of the outermost layer of the static electrification con­
trolled resin, and thus can be precisely controlled by simply control­
ling the amount of static electrification of the resin particles used to 
form the outermost layer. Since the state of static electrification of the 
toner can be precisely controlled, the kind and concentration of the 
pigment used can be freely selected. The presence of the outermost 
layer 3 prevents the pigment from breaking away from the toner. 
Further, it is possible to improve the fluidity and anti-block properties 
of the toner without any adverse effect. In addition, it is not necessary 
to use an additional static electrification controlling agent such as silica 
which might adversely affect the color shade of the toner.

Title: Method of enhancing the effect of cytotoxic agents
IPC: A61P35/00
Filed: 1989-02-23
Abstract: The activity of cytotoxic agents on target cells is 
enhanced through administration of a sensitizing agent to 
a patient prior to or simultaneously with administration 
of the cytotoxic agent. One or both of the two types of 
agents are attached to antibodies specific for the desired 
target cells, thereby enhancing the cytotoxic effect on 
target cells compared to non-target cells. The sensitizer 
and/or the cytotoxic agent may be attached to monoclonal 
antibodies specific for cancer cells to selectively eradi­
cate the cancer cells while minimizing toxicity toward 
normal tissues.

Title: High molecular weight poly-(toluenediamine aramides) and a method for their preparation
IPC: C08G69/32
Filed: 1989-06-22
Abstract: This invention relates to high molecular weight toluenediamine - 
containing polyamide resins formed by the reaction of a mixture of 
2,4-toluenediamine and 2,6-toluenediamine and derivatives thereof with an 
aromatic diacid or precurser thereof. The resulting polyamides are amorphous, 
as opposed to crystalline. Because they are amorphous, they lend themselves 
to a wide variety of processing techniques and because of their high molecular 
weight, they have outstanding physical properties.  
     The polyamides are prepared using a precondensate method wherein a 
mixture of the toluenediamine isomers and aromatic acid, usually in the form 
of the aromatic acid dihalide, is reacted at relatively low temperatures 
forming a precondensate and the precondensate subsequently polymerized in the 
presence of an acid acceptor.
