Title: Method for the automatic level adjustment in a local area network, in particular for a multiprocessor arrangement with a bus system of optical fibres, for the purpose of collision detection
IPC: H04L12/44
Filed: 1986-09-03
Abstract: A method is disclosed for automatic level matching in a local network, particularly for a multicomputer arrangement, comprising an optical bus system, for the purpose of collision recognition. Given a required level matching, the process is executed such that a fundamental phase is provided in which level matching devices respectively individually assigned to the computers are synchronized with one another. A first matching phase is provided in which all level matching devices simultaneously execute a process for setting a reference voltage to the lowest received level, whereby the sum of all attenuation components of the signal path at the receiving side of the appertaining computer is taken into consideration. A second matching phase is provided in which all level matching devices successively execute a process for setting the transmission level of their own transmitter such that the emitted light power at its own receiver leads to the receiving power registered as lowest, whereby the sum of all attenuation components of the signal path at the transmitting side of the appertaining computer is taken into consideration.

escent or colored product in a reaction catalyzed by an en­
zyme component of the reporter group. Also provided are en­
zyme immunoassays wherein detection of antibody is by a

Title: Method for the recovery and for the production of a pasteurized alpha-2-antiplasmin preparation
IPC: A61L2/04
Filed: 1987-01-20
Abstract: The process for the purification and, where appropriate, isolation and, where appropriate, pasteurisation of a solution of alpha2-antiplasmin entails, for the purification, dialysis against an aqueous solution of low ionic strength and removal of the resulting sediment. To isolate a particularly pure antiplasmin it is furthermore possible to purify the solution by chromatography using plasminogen bound to a solid phase. Also described is a process for the inactivation of organisms in an antiplasmin solution by heating in the presence of stabilisers. Plasmin prepared in this way can be used for therapeutic purposes.

Patent EP-0245028-A3 (EP)
IPC: H04M3/51
Filed: 1987-04-30
Abstract: A method and apparatus for identifying the class of an 
operator assistance call in order to reduce the operator work time 
for serving such a call. A customer dials 0 or dials 0 plus a 
directory number and is connected to a program controlled 
operator assistance system or switch (1). The switch initially 
connects the calling customer to a voice processing unit (14) and 
prompts the customer to speak a command or key a command 
code. The command or command code is recognized and used to 
direct the flow of the control program to selectively defer a 
connection to an operator position (24). For example, for person-­
to-person calls, the operator position is only connected after the 
called customer terminal answers. Advantageously, such a 
method and apparatus substantially reduces operator work time 
broad classes of frequently used operator assistance ser­
vices.

Filed: 1989-02-20
Abstract: Bei bekannten Erkennungsschaltungen für Sprachsignale wird 
nach einer Bandpaßfilterung für die Sprachgrundfrequenz des 
Mikrofonsignals die Einhüllende von Sprache desselben detektiert 
und das Detektionssignal zur Steuerung eines Regelverstärkers 
derart verwendet, daß dieser bei fehlendem Detektionssignal 
das Mikrofonsignal dämpft und bei vorhandenem Detektionssignal 
verstärkt. Ein derartiges Verfahren hat eine Detektionszeit zur 
Folge, die in einer Größenordnung von 200 ms liegt. Durch das 
neue Verfahren soll eine kürzere Detektionszeit erreicht werden.  
     Dies geschieht dadurch, daß die am Ausgang des Tiefpaßfilters auf­
tretenden Signale auf Amplitude und Dauer einer bestimmten Ampli­
tude überprüft werden und daß dann ein Sprachsignal erkannt wird, 
wenn mindestens drei aufeinanderfolgende Amplituden im Bereich 
der Sprachgrundfrequenz aufgetreten sind.  
     Die Erkennung von Sprachsignalen kann besonders in Verbindung 
mit einem Signalprozessor zur Verstärkungsregelung von Mikrofon­
signalen in störgeräuscherfüllter Umgebung erfolgen, wobei nur 
bei Vorliegen von Sprachsignalen eine Verstärkung stattfindet 
oder auch bei Wechselsprech- oder Gegensprechanlagen angewendet 
werden, um bei Vorliegen eines Sprachsignals das Signal in der 
betreffenden Richtung zu verstärken und in der Gegenrichtung 
zu dämpfen.

Title: Absorbent article
IPC: A61F13/15
Filed: 1989-03-23
Abstract: The present invention is directed to a disposable absorbent 
article, and particularly a sanitary napkin, having a 
flexure-resistant deformation element, the deformation element 
having a body facing surface which has a convex upward 
configuration when the sanitary napkin is worn. Primarily without 
relying on lateral compressive forces of the wearer's labia, the 
deformation element of the present invention relies on the lateral 
compressive forces of the wearer's thighs in order to form or 
maintain a convex upward configuration when the sanitary napkin is 
worn. In a preferred embodiment, the deformation element has a 
flexure means, and particularly a longitudinally extending flexure 
hinge, for inducing the body facing surface of the deformation 
element to have a convex upward configuration when the sanitary 
napkin is worn. In an alternatively preferred embodiment, the 
deformation element has a central region having a "W" shaped 
cross-section wherein the body facing surface of the deformation 
element having the convex upward configuration is located in the 
central region, generally symmetrically between the longitudinal side 
edges of the napkin. In another alternatively preferred 
embodiment, the deformation element has a cup-shaped front region 
and a back region having a convex upward configured body facing 
surface. The deformation element may be a moldable substance 
such as a foam, it may be reformable and/or it may be resilient.

Title: Road trailer for container transport
IPC: B60P1/64
Filed: 1989-09-15
Abstract: In order to displace a top frame (8), on which e.g. a 
container (15) is resting, on a road trailer chassis (1) 
which is longer than the top frame (8), said top frame is 
provided with guard plates (14) over the wheels (7) of the 
road trailer, so that by lowering the top frame and thus 
the guard plates to a position where they rest on the 
upper periphery of the wheels (7), the top frame and the 
container may be displaced relative to the road trailer.  
     This will happen when the road trailer (1) is being moved 
on the traffic lane whereby the top frame (8) will be 
displaced forward when the road trailer is moved forward, 
and backward when the road trailer is moved backward.  
     Thus, the kind of problems caused by wire tension or roll 
pinion under the top frame, such as operational problems 
due to high friction, will be avoided, and the demands on 
dimensioning and energy consumption will be heavier than 
those directed to the pinion according to the invention.
