IPC: H01S5/12
Filed: 1989-08-21
Abstract: An improved process for fabricating photonic circuits is 
disclosed. The inventive process starts with a growth of a base wafer 
comprising a stack of epitaxial layers of various materials. At least a 
portion of each of the material layers will ultimately be a functioning part of 
any of a number of devices which will form the PIC or will serve a role in at 
least one of the fabrication processing steps. Specific inventive processing 
steps are addressed to (1) interconnecting passive waveguides, active 
devices, and grating filtering regions without the substantial optical 
discontinuities which appear in the prior art, and (2) etching continuous 
waveguide mesas to different depths in different regions of the PIC so as to 
optimize the performance of each PIC device.

Patent EP-0465922-A3 (EP)
Title: Process for preparing isocyanate based foams
IPC: C08K3/02
Filed: 1991-06-25
Abstract: A process is described for the preparation of isocyanate-based foams. The foam is usually produced using chlorofluorocarbons (CFCs) as blowing agents. CFC-containing blowing agents can be replaced by alkanes, for example pentane, or water, which forms carbon dioxide. In this case, it is necessary to simultaneously use flameproofing agents. Surprisingly favourable product properties are obtained if, as proposed by the invention, red phosphorus in the form of a phlegmatised paste is used as the flameproofing agent. Even if a comparatively small amount is added, this improves the fire behaviour of the foam.

Patent EP-0719635-A3 (EP)
Inventor: YOSHIZAKI YUUICHI
IPC: B29C70/20
Filed: 1995-11-16
Abstract: A carbon-fiber reinforced plastics sheet (CFRP) is excellent in tensile
strength and modulus of elasticity, but defective in impact resistance and
fracture toughness, To overcome the defect, two aromatic polyamide fiber
reinforced plastics sheets (KFRP) are adhered to the opposite surfaces of
the carbon-fiber reinforced plastics sheet (CFRP) to thereby provide a
laminated structure, whereupon aramid fibers (a) are skewed at angles of
+30° - +60° with respect to the direction of an impact load. This
arrangement exhibits an improved shock absorbing efficiency and eliminate
surface distortion which would otherwise take place during lamination.
Further, a shock-absorbing structure may be produced from combining a
plurality of sheets (1, 2) assembled crosswise such that surfaces of the
respective sheets lie parallel to the direction of the impact load, and a cutout
recess (5) and a bulged portion (6) are formed at an end of the sheet
adjacent an intersection (3) of the structure. Thus, the one end of the sheet
including the cutout recess (5) and the bulged portion (6) undergoes local
buckling initiating from the intersection (3), and thereafter the entire assembly
is caused to become buckled. Since complete buckling of the entire
structure takes a certain period of time during which the impact energy can
be absorbed with reduction of the peak load, the shock-absorbing structure
is suitable for use in a crushable zone in aircrafts, automobiles or the like.
Patent EP-0703451-A3 (EP)
Inventor: TUBERGEN KAREN B
IPC: D21F7/06
Filed: 1995-08-23
Abstract: A method of monitoring a papermaking system containing impurities and
containing a dosage of a treating component to determine the level of treating under
operating conditions is disclosed which adds to the papermaking system a water
soluble fluorescent tracer in an amount proportioned to the amount of treating
component in the system, the fluorescent tracer being inert to the papermaking
environment. A sample solution is withdrawn from the system containing both the
component and tracer and the withdrawn sample is subjected to an analysis which
comprises the step of comparing the tracer concentration to a standard to determine
the concentration of tracer in the sample. After determining the variance of the
treating component dosage as compared to the standard, the dosage is adjusted by
changing the volume of water or the dosage of treating component in the
papermaking system to maintain an acceptable operating range of concentration for
the treating component. The method may be used for detecting leakage from the
system.

Abstract: Beschrieben wird eine Signalkoppelschaltung mit einem
Übertragungsanschluß, mit einem Koppeleingang, mit
einem Koppelausgang und mit einem Versorgungsanschluß.
Am Übertragungsanschluß steht ein aus einem Sendesignal
und einem Empfangssignal zusammengesetztes Übertragungssignal
an, am Koppeleingang liegt ein Eingangsstrom
an, zwischen dem Übertragungsanschluß und dem
Koppelausgang steht eine Ausgangsspannung an und am
Versorgungsanschluß steht ein Reststrom an. Der
Eingangsstrom wird als Sendesignal in das Übertragungssignal
eingekoppelt und das Empfangssignal als
Ausgangsspannung aus dem Übertragungssignal ausgekoppelt.
Die Signalkoppelschaltung weist drei in Reihe
geschaltete Impedanzen und einen Strommultiplizierer
mit drei Multipliereranschlüssen auf. Der erste
Multipliziereranschluß ist über die erste Impedanz mit
dem Übertragungsanschluß, über die zweite Impedanz mit
dem Koppelausgang und über die der zweiten Impedanz
nachgeschaltete dritte Impedanz mit Masse verbunden.
Der zweite Multipliziereranschluß ist mit dem
Koppeleingang und der dritte Multipliziereranschluß mit
dem Verbraucheranschluß verbunden. Der am Koppeleingang
anstehende Eingangsstrom bewirkt einen in den ersten
Multipliziereranschluß fließenden Signalstrom, der um
ein Vielfaches größer als der Eingangsstrom ist und
durch den das Sendesignal generiert wird. Der
Strommultiplizierer teilt den Signalstrom in den
Eingangsstrom und in einen weiteren Strom auf, der aus
einem am dritten Multipliziereranschluß anstehenden 
Reststrom und einem am vierten Multipliziereranschluß
anstehenden Massestrom zusammengesetzt ist. Der Massestrom
(I M ) ist dabei, sofern die Spannung zu dem ersten
und dem dritten Multipliziereranschluß eine Schwellenspannung
nicht unterschreitet, vernachlässigbar klein.
