The contact time (t) is pref. max. 90 secs.; and layer (I) is pref. precalcined petroleum coke with ash content 0.2-0.5%, 1% sulphur, and particle size 5-12 mm. Layer (I) is pref. covered with a loose refractory layer of high density, esp. corundum or magnesite. The Li content of Al should be below 2 ppm. its cracks in Al alloys, esp. AlMg alloys, are to be avoided.

Title: Probenentnahmesonde zur entnahme von fluessigkeitsteilmengen der verschiedenen phasen zweier nicht mischbaren fluessigkeiten
Inventor: KLUTH MANFRED DIPL ING
IPC: G01N1/10
Filed: 1979-08-17
Abstract: Bei einem Verfahren und einer Einrichtung zum Messen der Dauer von Laserstrahlungsimpulsen im Pico- und Nanosekundenbereich durch Autokorrelation zweier in bezug aufeinander zeitlicher verschobener Versionen der Strahlungsimpulse wird der Strahlungsimpuls in einer Richtung verbreitert und in dieser Breitenrichtung mittels eines Beugungsgitters zunehmend zeitlich verzögert. Dieses verzögerte Strahlungsbündel wird dann in zwei Teilbündel aufgespalten, von denen das eine räumlich invertiert wird. Anschließend werden das invertierte Teilbündel und das nichtinvertierte Teilbündel in einem nichtlinearen optischen Medium unter Erzeugung der ersten Oberwelle zur Wechselwirkung gebracht. Die räumliche Verteilung der Strahlungsintensität in dem vom nichtlinearen Medium erzeugten Ausgangsstrahlungsbündel doppelter Frequenz stellt zumindest eine Hälfte der Autokorrelationsfunktion dar. Die zeitliche Auflösung ist besser als 0,5 Picosekunden. Da an das nichtlineare Medium keine hohen Anforderungen hinsichtlich der Phasenanpassung gestellt werden, läßt sich das Verfahren mit leicht verfügbaren Kristallen bei geeigneter Wahl des Kristallmaterials, der Gitterkonstante des Beugungsgitters und des optischen Nachweissystems im Wellenbereich vom Blau bis über 10  μm im Infrarot verwenden.

Title: Deriving useful heating power from heat loss - using Diesel engine driving electric generator feeding exhaust gas heating element
Inventor: RUMMEL THEODOR PROF DR ING
IPC: F02G5/02
Filed: 1980-07-02
Abstract: Heat energy can be produced by running a Diesel engine (1) coupled to a generator (2), where the latter acting as a brake, increases the load on the Diesel and thus raises the heating loss output. This loss is conducted away via a cooling water circuit and in the form of exhaust gas residual heat. The heat exchanger for this purpose (4) is in the exhaust gas pipe of the diesel (1) with a feed and return pipe for the circulating medium. Between the Diesel (1) and the heat exchanger (4) is an electric heating element (6), fed from the generator (2), and raising the temperature of the exhaust gas. The heater (6) which is spirally wound, has three sections connected in star formation, and is followed by a soot filter (9) made of a porous ceramic and self-cleaning Thus, energy from the generator can be simply fed to the head exchange medium (exhaust gas) without a complicated construction of the heat exchange system.

IPC: D01H7/16
Filed: 1980-07-25
Abstract: A spindle assembly for a spinning frame comprises a spindle of pre-formed, thin-walled steel tube which forms a push-fit on an upward extension of a spindle-wharve, also of steel. The lower end of the tube is reinforced by a sleeve of tubular steel which is a push-fit on the spindle-tube, and whose upper end forms a shoulder on which rests the lower end of the bobbin tube.

Inventor: HAYASHI YUKICHI
IPC: G07F9/08
Filed: 1980-10-28
Abstract: Pulse signals indicating the insertion of coins detected separately according to the three denominations are applied to the terminals (T1,T2,T3). For instance, a pulse signal indicating the insertion of a 10-yen coin is applied to the terminal T1, a pulse signal indicating the insertion of a 50-yen coin to the terminal T2, and a pulse signal indicating the insertion of a 100-yen coin to the terminal T3. These pulse signals are applied to counters 1,2 and 3 respectively, and the outputs of the counters 1,2 and 3 are applied to arithmetic circuits 4,5 and 6, respectively. The arithmetic circuits (4,5,6) are made up of multipliers in which the count values of the counters (1,2,3) are multiplied by predetermined ratios, respectively. The predetermined ratios are set by setting circuits 4a,5a and 6a as required. For instance in the case where 10-yen, 50-yen and 100-yen coins are handled as described above, the ratios set by the setting circuits (4a,5a,6a) are 1,5 and 10 respectively.
