Patent EP-0339885-A3 (EP)
Title: Method and device for nondestructive evaluation
IPC: G01N29/00
Filed: 1989-04-21
Abstract: Ultrasonic surface examination, of interest in a variety of 
manufacturing and maintenance situations, is facilitated by a method which 
involves localized sensing of a surface wave by optical-fiber interferometry. The 
method is particularly applicable for examination of surfaces in confined spaces 
and wherever line-of-sight examination is difficult.
Patent EP-0351960-A3 (EP)
Title: Measurement and control of exhaust gas recirculation with an oxygen pumping device
IPC: G01N27/416
Filed: 1989-06-22
Abstract: An electrochemical device and method measures 
the percentage of exhaust gas in the intake air/exhaust 
gas mixture going to the cylinders of an internal 
combustion engine. Two electrochemical pump cells 
(21,31) and a support structure form a restricted volume 
(40) in communication through an aperture (41) to an 
ambient of intake air and exhaust gas mixture. Constant 
current is passed through a first pump cell (21) to 
cause a portion of oxygen molecules inside the 
restricted volume to be pumped out. A constant voltage 
across the second pump cell (31) causes substantially 
all the remaining O₂ molecules inside the restricted 
volume to be pumped out. Current flowing in the second 
pump cell is measured, the current being proportional to 
the percentage of O₂ inside the restricted volume and 
hence proportional to the percentage of O₂ in the intake 
air and exhaust gas mixture, which is a measure of %EGR.

IPC: B65G47/30
Filed: 1989-09-05
Abstract: A transfer apparatus for tire constituting members 
transfers them from a pre-process drum such as a carcass 
band forming drum (5) to a post-process drum such as a 
tire forming drum (19). The apparatus includes a 
movable frame (39) movable between the pre-process drum 
and the post-process drum, a holder (44, 49) mounted on 
the movable frame so that the holder is able to surround 
and grasp the tire constituting member, and a correction 
mechanism (166) mounted on the holder on a near side to 
the post-process drum to expand an axial end of the tire 
constituting member which is tapered due to rubber 
contraction and gravity for correcting the tire 
constituting member into a substantially cylindrical 
shape.

Patent EP-0363111-A3 (EP)
Title: Resists
IPC: B41N1/24
Filed: 1989-09-29
Abstract: The stencils (resists) currently employed in 
sand-blasting engraving techniques, for example of 
glass, are relatively flimsy, and thus it is easy to 
over-engrave and so to spoil the article being worked 
upon. In addition, the paper backing onto which the 
resist layer is applied is invariably uncoloured, and 
this makes it too easy to mistake the paper for 
engraved glass or  vice versa , adding to the 
difficulties of performing the engraving process 
correctly.  
     The present invention provides a resist the 
backing sheet of which is of a strong colour that 
contrasts with the colour of the surface to be engraved 
when thus engraved. The backing sheet preferably also 
contrasts with the colour of the resist layer itself, 
and is advantageously of a heavy-weight pre-gummed 
paper wherein the adhesive gum is provided in spaced 
particulate form.

Title: Polyarylene sulfides, process for preparation of the same, and resin compositions containing the same
IPC: C08G75/02
Filed: 1990-01-05
Abstract: A polyarylene sulfide has a ratio of weight-average 
molecular weight [Mw] to number-average molecular weight [Mn], 
a Mw/Mn, ranging from 2 to 5. The polyarylene sulfide is 
prepared by reacting a dihalo-aromatic compound with a sulfur 
source in an organic polar solvent at a temperature ranging 
from 220°C to 280 °C for 0.1 to 2 hours, yielding the 
polyarylene sulfide in a crude form and washing the crude 
polyarylene sulfide with an organic polar solvent at a 
temperature ranging from 100°C to 220 °C . Further, a resih 
composition is prepared by blending 100 parts by weight of 
the polyarylene sulfide with a filler in an amount ranging 
from 0.5 part to 500 parts by weight.  
     The polyarylene sulfide is provided with further 
improved properties, such as mechanical strength, heat 
deterioration resistance, chemical resistance and long-lasting 
durability.
Patent EP-0378169-A3 (EP)
Title: Film cassette
IPC: G03C3/00
Filed: 1990-01-09
Abstract: A film cassette (1) is disclosed wherein a 
film spool (5) having a filmstrip coiled about it is 
selectively rotatable in opposite directions to 
advance a leader portion (43) of the filmstrip 
through a film passage slit (26) to the outside of 
the cassette shell (3) and to return the leader 
portion to the inside of the cassette shell. A 
pile-like material (27), such as velvet or plush, 
consisting of short close flexible fibers (87) is 
secured to the cassette shell along the film passage 
slit to prevent ambient light substantially from 
entering the slit. The leader portion has at least 
one hole (89) adapted to receive a sufficient number 
of the fibers to allow the fibers to engage the 
leader portion to prevent its casual creep rearward 
in the film passage slit. The fibers have a 
resistance to displacement from the hole which can 
easily be overcome by rotating the film spool to 
move the leader portion.

Patent EP-0388601-A3 (EP)
IPC: D21F1/30
Filed: 1990-01-30
Abstract: 1.1. Formiersieb für die Naßpartie einer Papiermaschine, 
bestehend aus einem einlagigen oder mehrlagigen Ge­
webe aus Metall oder Kunststoff, das im Bereich 
seiner randseitigen Hochverschleißzone eine Verstär­
kung gegen Abnutzung durch Abrieb aufweist.  
         1.2. Um die Verschleißbeständigkeit der Hochverschleiß­
zonen zu erhöhen, ist bereits vorgeschlagen worden, 
in diesen Zonen zusätzliche Verschleißfäden in das 
Gewebe einzuweben. Dies hat jedoch den Nachteil, daß 
die Verstärkung bereits beim Weben angebracht werden 
muß, weshalb die Verstärkungsfäden für jedes Sieb 
mit einer anderen Breite neu plaziert werden müssen 
bzw. beim Weben der Breitenzuschnitt durch die Posi­
tionierung der Verstärkungsfäden bereits festgelegt 
ist, wodurch Webfehlern, die sehr häufig in der Nähe 
der Webkanten auftreten, nicht mehr ausgewichen wer­
den kann.  
         1.3. Die Erfindung vermeidet diese Nachteile dadurch, daß 
die Verstärkung in Form einer Verschleißmasse auf 
das Gewebe aufgebracht und mit ihm verbunden ist, 
wodurch die Herstellung der Verstärkung der Hoch­
verschleißzonen erst nach dem Weben und Fixieren 
oder auch erst nach dem Siebzuschnitt und dessen 
Nahtung erfolgen kann.
