Patent EP-0201339-A3 (EP)
IPC: G01N33/543
Filed: 1986-05-08
Abstract: An immunoassay device includes one or more reaction 
chambers. Each reaction chamber is adapted to receive and re­
tain a volume of test fluid in fluid communication with nonover­
lapping first and second reaction surfaces. To the first reaction 
surface is immobilized analyte binding partner that is in turn 
saturated with analyte conjugate: analyte component con­
jugated to one or more components, termed ligand/marker, 
that serve ligand and marker function as described herein. The 
analyte conjugate has a higher disassociation constant with 
reference to the immobilized analyte binding partner than does 
the analyte to be assayed. To the second reaction surface is im­
mobilized ligand/marker binding partner.  
     A test fluid sample is introduced into the reaction chamber 
and retained therein to permit two reactions to occur. In a first 
reaction between analyte and analyte binding partner at the 
first reaction surface, analyte proportionately displaces ana­
lyte conjugate into the test fluid sample. In a second reaction 
the displaced analyte conjugate becomes sequestered at the 
second reaction surface by bonding with immobilized 
ligand/marker binding partner. Thereafter the marker activity 
of sequestered analyte analog is measured, the measured ac­
tivity being a function of the analyte concentration that is refer­
able to standards and controls.  
     A test kit includes the immunoassay device in combination 
with comparative test results.

Title: Microapertured polymeric web exhibiting soft & silky tactile impression
IPC: B29C51/22
Filed: 1986-05-30
Abstract: §) A microapertured polymeric web exhibiting a substantially uniform soft and silky tactile impression on at least one of its surfaces. In a preferred embodiment the present invention relates to webs exhibiting a fine scale pattern of discrete surface aberrations, each of said surface aperrations having its amplitude oriented substantially perpendicular to the surface in which said surface aberration originates. At least one tiny aperture (microaperture) is provided substantially coincidental with the maximum amplitude of each surface aberration. The discontinuity created by the aperture at the peak of each of the surface aberrations substantially reduces the resistance to both compression and shear of each individual surface aberration. In addition the volcano-like edges formed at the periphery of each microaperture are typically in the form of thin, irregularly shaped petals which not only reduce the total contact area with the user's skin, but which are also easily deflected when re'ative movement with the user's skin occurs. Microapertured webs of the present invention are also relatively quiet when subjected to movement, making them particularly suitable for use as topsheets and/or backsheets in disposable absorbent structures such as adult incontinent briefs.
Patent EP-0225006-A3 (EP)
Title: Improved current-sensing arrangement and method for a circuit-interrupter control circuit
IPC: H02H3/093
Filed: 1986-09-25
Abstract: An improved current-sensing arrangement (10) and method are provided for supplying a signal (e.g. at 14) that suitably represents line current (e.g. in 12) over a wide current range. The current-sensing arrangement utilizes the signals from an iron core transformer (32) and an air core transformer (42) along with transition and scaling arrangements fe.g. 56,58,70,62,64 and 68) to provide the sensed current signal. The range of operation includes currents for which the iron core transformer exhibits saturation effects and currents for which the air core transformer does not contribute to the combined output signal. Additionally, the range of operation includes currents for which both the transformers contribute to the combined output signal. The output of the iron core transformer dominates the combined output signal for low currents, the output of the air core transformer dominates at high currents, and the transition from the domination of the iron core transformer to the air core transformer is gradual and occurs over a mid-range of current with contribution from both transformers.Accordingly, the combined output signal suitably represents the sensed current over a wide current range due to the contribution of the iron core transformer at low currents where no saturation effects are present and the contribution of the air core transformer at high currents with no saturation characteristic; a smooth transition being provided over a wide current range where both transformers contribute to the output and dominant contribution being provided by the transformer that is most accurate for the particular current.

Abstract: A bandpass filter comprises a reactively intercoupled pair 
of parallel-resonant circuits (1, 2) to one of which a pair of 
signal input terminals (15, 16) are connected and to the other of 
which a pair of output terminals (17, 18) are connected. Tuning 
of the filter is accomplished by varying the capacitive component 
of each circuit by means of a tuning voltage applied to a further 
input (19). In order to compensate for the deviation from the 
optimum intercoupling which would otherwise occur with change of 
tuning frequency the capacitive component of each resonant 
circuit comprises at least three capacitors (5, 6, 7 and 8, 9, 
10) in series, each set of three capacitors effectively forming a 
variable capacitive voltage divider. The two junction points of 
the three capacitors of each set are each connected to the 
corresponding junction point in the other set by means of a 
respective bidirectional reactive coupling (13 and 14
