Title: Koplanarer phasenschieber mit konstanter dämpfung
Inventor: SCHOEBEL JOERG
IPC: H01P1/12
Filed: 2003-06-12
Abstract: Die Erfindung beinhaltet eine Vorrichtung zur Phasenverschiebung für elektrische Hochfrequenzleitungen (36), bei der die Phasenverschiebung im wesentlichen durch gezielte Wahl der Leitungslänge erreicht wird, wobei es sich bei der Vorrichtung im Kern um eine mit Koplanarleitungen versehene Schaltanordnung (30) handelt. Die Einstellmöglichkeiten der verschieden langen Koplanarleitungen (32, 34) bezüglich Ohm'scher Dämpfung und Impedanz sind dabei so vorgewählt, dass sich auf den wahlweise ansteuerbaren, verschieden langen Leitungswegen (32, 34) der Schaltanordnung (30) im Wesentlichen gleiche Ohm'sche Dämpfung und Impedanz ergeben. Als Einstellmöglichkeiten kommen zum Beispiel die Breite w der jeweiligen Mittelleiter (24) und die Breite b der Aussenleiter (22) sowie der Abstand g zwischen Mittelleiter (24) und Aussenleiter (22) in Betracht. Solche Phasenschieber sind für die Strahlschwenkung bei Gruppenantennen in der Kraftfahrzeug-Sensortechnik geeign.

Filed: 1972-11-09
Abstract: 1378983 Digital data storage INTERNATIONAL BUSINESS MACHINES CORP 6 Oct 1972 [17 Nov 1971] 46161/72 Heading G4C Data are written on sequential tracks of a disc stack cylinder until a break point is reached, after which data are written on another disc stack or on sequential tracks of another cylinder of the same stack. In one embodiment having three disc packs each with 20 disc faces, each block of data in a string corresponds in length to one track on a disc. Assuming module 0 has a first available track at cylinder 2, face 5, the first 15 blocks of a string are recorded on faces 5-19 of cylinder 2 and the next 5 blocks of the string are recorded on cylinder 3 starting at face 0, for example. Blocks 20 are recorded in module 1, for example at first available cylinder 5 of faces 10-19 and cylinder 6 of faces 0-9. Similarly blocks 40-59 are recorded in module 2 at first available cylinder 1 of faces 4-19 and cylinder 2 of faces 0-3. This arrangement may require head movement for each group-of 20 blocks, depending on the location of the first available face in each module. In a second embodiment, blocks are recorded in succession on the first available faces in each module taken in turn and head movement only takes place if overflow from the last module occurs. Taking the same example as above, blocks 0-14 are recorded in module 0, cylinder 2, faces 5-19; blocks 15-24 in module 1, cylinder 5, faces 10-19; blocks 25-39 in module 2, cylinder 1, faces 4-18; block 40 in module 2, cylinder 1, face 19; blocks 41-59 would then be recorded in module 0, cylinder 3, faces 0-18. Algorithms for calculating the addresses of the various blocks in storage are described.

Title: Multicomponent plastics mixing head - has expansion element in each feed line to compensate for any sudden pressure increase
Inventor: SCHLUETER KLAUS DIPL ING
IPC: B29B7/76
Filed: 1973-03-30
Abstract: A metering and mixing appts. for >=2 plastics components comprises a circuit for each component leading to the mixing head and comprising a feed and return line from the reservoir for the component; a valve in the mixing head enables either mixing followed by ejection to be carried out or alternatively return flow of the unmixed components along the return lines. Each feed line comprises an elastic unit such as a diaphragm with a gas cushion, or a spring or a flexible length of tube or loops in the feed line, so that when a sudden pressure increase occurs in the feed line, expansion can take place to compensate for it. This arrangement enables pressure shocks to be minimised, thus increasing the life of the components and preventing disturbances from occurring in the mix ratio.

Title: Alumina prodn. from bauxite by Bayer process - with immediate filtration of the slurry to prevent pptn. of alumina
Inventor: SCHEPERS BERNHARD DIPL CHEM DR
IPC: C01F7/0646
Filed: 1973-06-09
Abstract: The autoclave slurry is passed directly to a filler (pref. a revolving drum filter), and filtered under a press. of 0.5-5 atm. gauge (produced by steam), whereby the pptn. of alumina is virtually prevented. The application of press. (by steam) instead of the conventional suction under vacuum retards the cooling of the lye, whereby the filtration is facilitated. Dilution of the slurry is unnecessary so that the expensive concn. of the recycle is not applied.
