Abstract: Afin de permettre le transport de palettes (10) à différentes vitesses sur des transporteurs à chaînes (14, 16) dans diverses sections d'un trajet de transport sans qu'il soit nécessaire d'utiliser des engrenages de commutation pas-à-pas, les palettes sont posées sur au moins deux transporteurs à chaîne (14, 16) qui se déplacent à des vitesses différentes. En commandant l'entraînement par friction entre les éléments de support (22 à 28) des palettes (10) et les convoyeurs sans fin (14 et 16), on peut prédéterminer le transporteur à chaîne avec lequel les palettes se déplaceront à un moment donné, alors qu'un mouvement relatif essentiellement dépourvu d'entraînement est possible entre la palette (10) et l'autre transporteur à chaîne. Ce dernier ne sert alors temporairement que de support vertical d'un côté de la palette.

Abstract: Inverterschaltungen weisen Brückenzweige auf, die z. B. aus zwei in Reihe geschalteten Transistoren (T1, T2) mit je einer Freilaufdiode (D1, D 2) bestehen. Ein kritischer Betriebszustand tritt auf, wenn der Freilaufstrom durch die eine Diode (D1, D2) dadurch abkommutiert wird, daß der andere Transistor (T2; T1) eingeschaltet wird. Der Rückstrom durch diese Diode kann beim schnellen Einschalten dieses Transistors so hohe Werte annehmen, daß die "dynamische" Sperrfähigkeit der Diode überschritten und die Diode zerstört wird. Der Laststrom und der Steuerstrom des Transistors werden daher gegengekoppelt, so daß der Transistor langsamer einschaltet und vorübergehend einen Teil der sonst an der Diode liegenden Spannung übernimmt.

Abstract: Counting devices are used for the measurement of electrons emanating from an object (15) after interaction with an incident radiation beam. Using these counters, detection can also take place when electron pulses have a small current contents. By the addition of a DAC (76) and possibly a sample-and-hold circuit, spectometric measurements are possible so that absolute potential values of a measuring point can be determined. For measurement of comparatively large currents, digital feedback can be used. Multi-sampling enables much faster measurements.

Abstract: A process for the production of p-xylene and o-xylene by catalytically isomerising alkyl aromatic hydrocarbons involves subjecting a substantially C₈ alkyl aromatic hydrocarbon mixture to a temperature of from 250°C to 550°C in the presence of an improved catalyst. This catalyst consists of a high silica zeolite composite in acid form containing small amounts of metals of Group VIII of the Periodic Table dispersed on a porous matrix. As a result of the subjection of the hydrocarbon mixture to high temperature in the presence of such catalyst, the xylene content of the mixture is isomerised to provide an isomeric mixture in equilibrium. Any ethyl benzene present is simultaneously dealkylated. Thereafter, the reaction medium is cooled, the lighter or top product consisting of a benzene-toluene mixture is separated, the heavier bottoms product rich in p-xylene and o-xylene isomers is withdrawn and such bottoms product is treated in any known manner to separate therefrom the p-xylene and o-xylene as individual products.

Title: Iron-releasing monokine.
Inventor: KLOSTERGAARD JIM
IPC: C12P21/00
Filed: 1988-01-06
Abstract: A substantially purified preparation containing one or more soluble Iron-Releasing Monokines and a method of preparing and using same are disclosed. The monokine is heat labile and is retained by ultrafiltration on a YM-10 membrane. Molecular exclusion chromatography of macrophage conditioned supernatant containing the monokine yields fractions in the 30,000 to 65,000 relative molecular weight range with iron-releasing activity. Kinetic studies show that the monokine is rapidly released from activated macrophages after triggering with bacterial endotoxin, reaching plateau levels within 2-4 hours. The response of cells to the monokine depends on both the dose of the monokine administered and the duration of its exposure. The Iron-Releasing Monokine is distinct from other factors secreted by activated macrophages, such as a cytolytic factor and Respiratory Inhibition Factor which causes reversible lesions in the electron transport chain.
