Patent EP-0210556-A3 (EP)
IPC: G02B6/125
Filed: 1986-07-18
Abstract: Herstellung modenunabhängiger, integriert-optischer 
Lichtwellenleiterstrahlteiler, wobei in einer, auf einem geeig­
neten Substratmaterial erzeugten, lichtwellenleitenden 
Schicht ein als Strahlenteiler wirkendes Paar von definierten 
Grenzflächen angeordnet ist, welches diese lichtwel­
lenleitende Schicht unterbricht.  
     Aufgrund der durch die Grenzfläche entstehenden Brech­
zahldifferenz wird ein Teil des geführten Lichtes an der Grenz­
fläche reflektiert. Aus der Breite der Grenzfläche und ihrem 
Winkel zur Wellenleiternormalen wird das Teilungsverhältnis 
eingestellt. Hierbei läßt sich ein Arbeitspunkt finden, bei dem 
die Reflexions- und Transmissionskoeffizienten für beide Pol­
arisationsarten TE und TM des geführten Lichtes gleich groß 
sind, so daß dieser Abzweiger polarisations- und moden­
unabhängig arbeitet. Des weiteren lassen sich auch Arbeits­
punkte angeben, bei dem das Bauteil als Polarisator einges­
etzt werden kann.

Title: Method for making layered glass
IPC: B65G49/06
Filed: 1987-05-22
Abstract: To produce panes of laminated glass from two sheets of silicate glass (1, 16) and from an interlayer thickness of a plastic film (8) glued to the two glass sheets (1, 16), the liquid adhesive material intended for the two adhesive layers (2, 17) is applied each time in the form of a coherent and uniform film of a definitive thickness of the upper surface of the glass sheets (1, 16) oriented horizontally.

Patent EP-0283645-A3 (EP)
Title: Flexless telephone
IPC: H04M1/72502
Filed: 1988-01-16
Abstract: If, in a handset of a cordless telephone, the battery (15) housed in the handset casing goes flat, a voltage monitoring circuit (14) connected to the battery detects that the battery voltage has fallen below the pre-defined minimum level and activates a warning signal via a first microprocessor circuit (13). If the flat battery is replaced with a charged or recharged spare battery (29) while a call is in progress, the transmission power of the handset (10) fails. This failure is detected by a field strength evaluator (25) of the base station (20) and reported to a second microprocessor circuit (23) of the base station. This prevents the telecommunications component (26) of the base station from interrupting the telecommunications link with the user. After a pre-defined time, the second microprocessor circuit clears down the radio link between the base station and the handset and, once the battery has been changed, a new radio link is set up to the handset on a free radio channel. <IMAGE>

Title: System for scanning documents without loss of image data
IPC: G06F3/00
Filed: 1988-12-06
Abstract: A document processing system directs documents (D) at a 
high rate of speed past an optical scanner (16) which 
captures written information on the documents as video 
image data. The video image data is directed over a 
data channel (28) to a host computer system (30) where 
the data is stored on a mass data storage device for 
subsequent retrieval. A buffer (26) is provided between 
the scanner (16) and the data channel (28), which 
receives data a rate which varies in relation to the 
amount of information present on the documents. Data is 
extracted from the buffer (26) at a rate which is 
limited by the host computers channel transfer rate. A 
control means (11) is associated with the buffer and is 
operable for controlling a hierarchy of actions ranging 
from slowing down the incoming data stream to stopping 
the data stream altogether in order to prevent any loss 
of video image data due to overfilling of the buffer.

Title: Method for measuring x-rays or gamma radiation and device for this
IPC: G01T1/36
Filed: 1988-02-23
Abstract: According to the invention x-rays gamma radiation is measured by means of the Compton effect utilizing scattering towards a long and narrow filament of polyethylene, lucite or another material having a low average atomic number. The radiation scattered from the filament (4) is measured by a detector (8) and the radiation to and from, respectively, the filament is shielded by collimators (2,3 , 6 and 7). The detector (8) is connected to a multichannel analyzer which, in turn, is connected to a computer performing a reconstruction of the primary radiation from the measured spectrum. The measuring method is practical in use and very accurate.

Title: A method and an arrangement for controlling the method of operation of a matrix printer
IPC: B41J9/44
Filed: 1988-11-09
Abstract: A matrix printer comprises a printing head which includes a 
plurality of printing needles (11) each having a respective 
electromagnetic maneuvering device (10) by means of which 
the needle, carried by a spring-biassed, movable armature 
(12), can be caused to carry out a working cycle, which 
includes a working stroke and a subsequent return stroke. 
The maneuvering device (10) is activated by temporarily 
lowering the magnetomotive force in the magnetic circuit 
(12,14) of the device from a previous, constant value. The 
previously attracted armature (12) will herewith commence 
to move in a direction away from the stationary part (14) 
of the magnetic circuit as a result of the spring force 
acting on the armature. The magnetomotive force is then 
caused to return to its previous value. For the purpose of 
reducing the noise and wear generated by the armature (12) 
and to reduce the tendency of the armature to rebound, the 
armature is slowed down during the final stage of its 
return stroke, by again lowering the magnetomotive force 
temporarily for a limited part of the time taken to effect 
the return stroke.

Abstract: A method of forming a superconductive joint between 
superconductors made of filaments of superconducting 
material embedded in a matrix material utilizes two baths

superconductors into a superconducting joint. 
Superconducting joints may thereby be made under ordinary 
atmospheric conditions between superconducting wires having 
similar and/or different matrix materials.
