Patent EP-0165801-A3 (EP)
IPC: G01N1/20
Filed: 1985-06-17
Abstract: According to the method and apparatus of the invention 
a fermentation liquor is aseptically sampled by withdrawing 
a recycle stream of fermentation medium from the fermenta­
tion vessel (1), passing the recycle stream through a closed 
tubular loop (4) back into the fermentation vessel, the loop 
having at least one tubular section (3) constructed of a 
porous filter material permeable to the liquor, but not by the 
culture microorganism or other solids. Liquor which filters 
through the porous tubular section is collected as the 
sample. Internally the tubular section is kept free of deposits 
clogging the filter by the flow of liquid around the recycle 
loop.
Patent EP-0155222-A3 (EP)
IPC: C08G18/10
Filed: 1985-02-26
Abstract: A polyester polyurethane compound is formed by react­
ing trans-1,4-cyclohexanediisocyanate with a mixed poly­
ester. The mixed polyester can be the copolymerization con­
densation product of an aliphatic dicarboxylic acid or an aro­
matic dicarboxylic acid, or a separate physical blend thereof 
reacted with a polyol. The polyurethane can also contain 
small amounts of non-extractable epoxies and car­
bodiimides. The urethane has very good hydrolytic stability 
in comparison with prior art polyurethane systems and also 
very good fuel resistance and anti-icing resistance. A prefer­
red area of use is as aircraft fuel tanks and anti-icing com­
ponents.

Title: Pad-dyeing process for wool
IPC: D06P3/14
Filed: 1986-01-23
Abstract: Vinylsulfonyl dyes, if padded from acidic liquors, produce on wool merely dyeings having a poor yield and only moderate fastness properties if the pad-beam method is used. It has been found according to the invention that padding from weakly alkaline liquor (pH 7-9) with sodium bicarbonate as fixing alkali and subsequent batching (6-24 hours) of the material produces good coloristic results especially on wools with a low-felting or non-felting finish.

Patent EP-0195950-A3 (EP)
IPC: H02M7/5383
Filed: 1986-02-27
Abstract: A new device meant to synchronize free running oscilla­
tor frequency with a feedback saturable transformer and 
square wave output voltage.  
     It may find application in space or ground uses. Its un­
iqueness is given by the insertion within the feedback circuit 
(made up of a saturable transformer) of a synchronizing circuit 
which causes feedback transformer saturation at times strictly 
dependent upon synchronism generator, without impeding 
frequency adjustment by means of a potentiometer.

Title: Method and apparatus for coating the edges of a plate-like preform
IPC: B29C33/40
Filed: 1986-05-02
Abstract: An apparatus and process for molding the edges of a board-shaped blank with plastic material. A one-piece mold is provided made of a material with rubber-like elasticity and having a C-shaped cross section. Two free legs of the mold receive between themselves the edges of the blank and rest against the blank from the top and bottom. The mold is surrounded by a divided mold box, having upper and lower parts supporting the mold on all sides and being compressible perpendicularly to the plane of the blank. Upon compression, free legs of the mold are forced against the blank. In the mold box, spacing elements are arranged on top of and beneath the blank to limit the distance of movement of the parts of the mold box and the compression of the mold.

Title: Arrangement for switching a vacuum cleaner on and off
IPC: H01H9/06
Filed: 1986-06-16
Abstract: The arrangement for switching on and off of a vacuum cleaner comprises a switch which is integrated in a printed circuit board disposed below the cover of the vacuum cleaner housing. In the cover there is formed a resilient tongue having an upwardly projecting handle portion so that a bowl-shaped cavity is created in the free end of the resilient tongue. The switch extends into said bowl-shaped cavity and is operated by means of the resilient tongue. The production and mounting of the arrangement for switching on and off of the vacuum cleaner require only low expenditure of labor.

Title: Method for working joints in concrete tubes, and device for carrying out the method
IPC: F16L1/028
Filed: 1988-10-26
Abstract: It has hitherto been possible to effect joint sealing in concrete tubes only by pouring in the bottom region or by introducing a joint strip designed as a lip seal. In these cases, the sealing force is low, with the result that the liquid passing through the tubing may leak out in the event of relatively high pressures. By cutting open the joint to a predetermined depth and predeterminable width, the possibility is provided for fitting strand- like seals with high compression, and to do so over the entire tube circumference, thus guaranteeing perfect sealing even for a high liquid pressure.

Abstract: Das beschriebene System zur Übertragung von Videobildern 
enthält einen Hybrid-Codierer, der die ankommenden Daten 
eines Videobildes blockweise codiert. Auf der Empfänger­
seite macht ein Hybrid-Decodierer die Codierungsschritte 
des Hybrid-Codierers rückgängig. Die ankommenden Blöcke 
eines Videobildes werden unter anderem durch eine Trans­
formationseinheit (T) transformiert und einen Quantisie­
rer (Q) quantisiert. Um das System an Übertragungsbitra­
ten zwischen 64 kbit/s und 2 Mbit/s optimal anpaßbar zu 
machen, ist eine Strukturiereinheit (SE) vorgesehen, die 
mehrere Blöcke, die einen zusammenhängenden Ausschnitt 
eines Videobildes darstellen, zu einem Makroblock zusam­
menfaßt. Jedem Makroblock ordnet sie ein Makroattribut 
zu, dem zu entnehmen ist, welche Eigenschaften für alle 
Teilblöcke des Makroblockes als identisch gelten und wel­
che nicht. Zu solchen Eigenschaften gehören z.B. Aussagen 
über den Bewegungsvektor eines jeden Teilblockes, der 
z.B. für alle Teilblöcke gleich sein kann.  
     Bei Verwendung eines gesonderten Makroattributes (NON) 
gibt es keine Eigenschaft, die für alle Teilblöcke eines 
Makroblocks als gleich gilt, vielmehr sind die Eigen­
schaften jedem Teilblock selbst zugeordnet.  
     Im Bedarfsfall werden die Makroblöcke selbst wiederum wie 
Teilblöcke behandelt, d.h., zu noch größeren Einheiten 
zusammengefaßt. Bei der Übertragung von Standbildern er­
gibt sich dadurch eine besonders effektive Codierung.

coupling of the present invention is designed so that 
fluid communication can only occur after the coupling 
halves (11,12) are joined and sealed together. Fluid 
communication is cut off before the coupling halves 
can separate from each other thereby minimizing 
leakage during the coupling operation.
