Patent IE-911057-A1 (IE)
Title: Level converter
IPC: H03K19/0175
Filed: 1991-03-28
Abstract: A level converter (PU) which is used for converting digital ECL input signals into digital CMOS output signals, is preferably connected together with a preamplifier (VV). In the preamplifier (VV), the ECL input signals are conditioned in such a manner that they can be optimally converted by the level converter (PU). The level converter (PU) can be optionally driven directly from the preamplifier output (Q) or indirectly via a bipolar transistor (Q14) in emitter follower circuit. Only one of the complementary outputs (Q,Q) of the preamplifier (VV) is needed for driving the level converter (PU). This is made possible by applying a reference voltage (VB2) to the gate terminal of a MOS transistor (M11) of the level converter (PU).

Title: Interactive home information system
IPC: H04N5/45
Filed: 1991-09-27
Abstract: An interactive videotex system with distributed processing and storage of video picture information in nodes (12) disposed throughout a cable television distribution system. The nodes (12) are coupled to the feeder cable (30) of the cable distribution system. Each node (12) in the system receives a substantially identical copy of the interactive video picture information and related data from a regional processing center (4). The users at home televisions (38) associated with a particular node (12) interact directly with the video picture information in that node (12), rather than with the information stored in the regional processing center (4) or some other remote location, which enables the system to quickly display photographic quality images and complex graphics, as well as sound, at the users' televisions (38) in response to commands received by the users. The nodes (12) can also be used for decompressing compressed television programming and distributing the decompressed programming to home televisions (38) connected to the system. <IMAGE>

Inventor: DEUTSCHMANN GOTTFRIED
IPC: B32B/
Filed: 1991-02-06
Abstract: Für die Herstellung der elektrischen Isolierung der Wicklung einer elektrischen Maschine nach dem Vakuumdruckimprägnierverfahren werden vor dem Einlegen der Wicklung in die Nuten (6) des Stators oder Rotors die Nuten durch ein Laminat (5) ausgekleidet, welsches zumindest in einer Laminatschicht eine elastisch komprimierte Masse aus hochelastischen, elektrisch isolierenden Fasern und ein verfestigtes, in der Wärme jedoch noch erweichbares aushärtbares Kunstharz enthält, das die Fasermasse in ihrem komprimierten Zustand hält. Nach Einlegen der Wicklung und Verschliessen der Nuten (6) wird der Rotor oder Stator einer Vakuumdruckimprägnierung unterzogen und anschließend in einem Ofen ausgehärtet. Beim Imprägniervorgang dringt das heiße Tränkharz insbesondere auch in die Poren des elastisch expandierbaren Laminats ein. Dadurch wird das Kunstharz zum Schmelzen gebracht, wodurch sich die Fasermasse elastisch entspannt und dabei die anschliessenden Zwischenräume in der Nut gleichmäßig ausfüllt.
Patent WO-9319823-A1 (WO)
Inventor: EDER WALTER
IPC: A63C5/00
Filed: 1993-03-31
Abstract: Conformément à l'état de la technique, les spatules de skis de fond fabriquées jusqu'à maintenant comportent une courbure simple et forment de ce fait un angle de 90° environ par rapport aux parois de la trace. Lors du contact d'une spatule de ski de fond habituelle avec la trace, la résistance au cisaillement et la neige tombée dans la trace sous l'effet du cisaillement entraînent une diminution de la vitesse du fondeur. Selon l'invention, une courbure double de la spatule du ski de fond permet de transformer la résistance au cisaillement en une résistance au glissement nettement moindre, de réduire considérablement l'apport de neige dû au contact du ski avec les parois de la trace et d'augmenter de ce fait la vitesse virtuelle du fondeur. Le fait que les parois de la trace et que la surface de glissement à courbure double de la spatule soient en contact de manière tangentielle, entraîne une meilleure maîtrise du ski et une diminution sensible du risque de chute.

Title: Process for removing sulfur compounds from gas and liquid hydrocarbon streams
Inventor: HAKKA LEO ERNEST
IPC: B01J20/22
Filed: 2001-03-09
Abstract: The present invention provides a process for removing sulfur compounds including sulfur in the (-2) oxidation state such as mercaptans, dialkyl sulfides, carbonyl sulfide, hydrogen sulfide, thiophenes and benzothiophenes, from liquid or gas feed streams, particularly hydrocarbon feed streams such as, for example, natural gas and refinery process streams. According to the process, such a feed stream including these sulfur impurities is contacted with an absorbent which includes a metal ion-containing organic composition such as, for example, iron, copper, lead, nickel, tin, zinc or mercury cation-containing phthalocyanine or porphyrin to thereby form sulfur-metal cation coordination complexes in which the oxidation state of the sulfur and the metal cation remains essentially unchanged. The complexes are separated from the feed stream, and the absorbent is regenerated by disassociating the sulfur compound from the complexes.
