Abstract: Die Erfindung betrifft eine Vorrichtung zum Aufbewahren von entwickelten 
und/oder vergrößerten Fotografien aller Formate.  
     Die wesentlichen Merkmale der Erfindung bestehen darin, daß die 
Fotografien (7) aus in Alben einhängbaren Bögen (3), die an einer Seite Lochungen ( aufweisen, angeordnet sind.  
     Vorzugsweise sind die einhängbaren Bögen im Querformat größer als das Album und haben einen Falz (11).

Title: Method for realizing a control procedure in combination with the realisation of a hold state of a line in a calculator-controlled communication system, especially a key telephone system
IPC: H04Q3/545
Filed: 1989-07-31
Abstract: If a terminal (T1) is put into the idle state (on-hook) by the subscriber who has previously placed an external line (L) on hold, the controller produces a visual display at the authorised terminals which indicates the then existing seizability by other subscribers. If such a seizure does not occur within a predeterminable period of time, the subscriber conducting the original call is automatically dialled by the controller if he is in the idle state and, when he answers, the connection to the external line (L) is restored. If he is busy, a periodic check is made as to whether the subscriber concerned has become available. During this checking time, seizure by the other subscribers is possible, for example by actuating the line key which assumes a particular reset state. <IMAGE>

Abstract: Die Erfindung betrifft die Verbesserung eines Schalters gemäss Hauptpatent 
P 38 10 091. Bei diesem Schalter werden über eine Kompressionseinrichtung 
stromschwache Lichtbögen beblasen, wobei bei stromstarken Lichtbögen ein 
Verschlussorgan (8) die Kompressionseinrichtung verschliesst und eine 
Selbstbeblasung über einen Gasspeicherraum (9) und eine Druckkammer (3) 
erfolgt.  
     Bei diesem Schalter steht nach der Unterbrechung eines stromstarken 
Lichtbogens heisses Gas geringer Dichte vor der Schaltstrecke. Dies ist für 
eine erneute Lichtbogenbeblasung von Nachteil.  
     Eine Bereitstellung kalten Löschgases wird auch in einer solchen Schalt­
situation dadurch bewirkt, dass ein Ventil bei der Einschaltung öffnet und 
dadurch eine Verbindung zwischen der Druckkammer (3) und dem Kompressions­
raum (11) schafft, wodurch frisches Löschgas aus der Schaltkammer in die 
Druckkammer (3) gesaugt wird und für eine erneute Lichtbogenbeblasung zur 
Verfügung steht.

Patent EP-0368273-A3 (EP)
IPC: G01N33/543
Filed: 1989-11-08
Abstract: A method of assay for antigen comprising the following 
processes (A), (B), (C) and (D): 
   Process (A): A process in which the antigen to be assayed in 
the subject solution is bound with a functional group or 
marker to form a modified antigen.    Process (B) : A process in which the modified antigen is 
bound to a carrier via an antibody against the antigen and 
then the carrier is separated from the subject solution.    Process (C): The following process (a) or (b):  
(a) A process in which the modified antigen is diassociated 
from the carrier.  
(b) A process in which the modified antigen-antibody complex 
comprising the modified antigen and the antibody against the 
antigen is diassociated from the carrier.    Process (D): A process in which the modified antigen or 
modified antigen-antibody complex of Process (C) is assayed.     
     This method permits assay for antigens with high sensiti­
vity based on characteristic features of the sandwich method, 
using an antibody against a single epitopic site, and also 
permits assay for low molecular substances, which have never 
been assayed by the conventional sandwich method, with higher 
sensitivity in comparison with the conventional competitive 
method.

Title: Picture motion measurement
IPC: H04N17/00
Filed: 1989-09-01
Abstract: A region from two frames of a television picture is 
subjected to Fourier transform in processing stages (3 and 4) one 
via a picture memory (2), and the resulting transforms compared 
in a comparator (5) whose output is subjected to inverse Fourier 
transform in a processing stage (6). The output of comparator 
(5) is also applied to a sample rate modifier (7) in which this 
output is enlarged prior to being subjected to inverse Fourier 
transform in a further processing stage (8). The outputs of 
processing stages (6 and 8) are respectively low and higher 
correlation functions of one pixel and one-quarter pixel 
resolution respectively. A given number, say 20, of sample 
points of greatest magnitude in the low resolution correlation 
function are selected in a largest vector selector (9) whose 
coordinates are used in a peak locator (10) which locates the 
peaks in the higher resolution correlation function associated 
with the selected samples to produce coordinates for these peaks 
to quarter pixel accuracy. A limited number of these, say 10, 
can be selected by a vector limiter (11) if used with a system 
having limited data capacity for motion vectors.
