Abstract: In a multiprocessor system, the events likely to modify the partitioning of the processes to the processors (CPU, CPUi) trigger the execution of a dispatching routine tasked with defining the new partitioning as a function of the events and of various data. When the number of processors (CPU, CPUi) is considerable, the routine has to be optimised. With this aim, the routine is subdivided into several specialised microprogramme modules for determining the partitioning respectively in response to particular categories of events. A central microprogramme module takes account of the events other than those processed by the specialised modules. Application to multiprocessor computer systems. <IMAGE>

Abstract: Un système sert à générer des signaux de commande ou d'ajustement du châssis d'un véhicule à moteur d'une voiture particulière et/ou d'un véhicule utilitaire dont les mouvements peuvent être commandés ou ajustés. Afin de minimiser les mouvements de la carrosserie, les signaux de détection des courses de compression (Xarvl, Xarvr, Xarhl, Xarhr) et/ou des vitesses de compression de la suspension sont interconnectés de manière répétée et s'influencent mutuellement, par l'intermédiaire de grandeurs qui représentent l'état de conduite, par exemple les accélérations transversales et longitudinales (aq, al) et la vitesse du véhicule. Les mouvements collectifs de la carrosserie, notamment les mouvements propres de la carrosserie (par exemple les mouvements d'oscillation, de tanguage et/ou de roulis (Zb, alphab, bêtab), ou les déplacements verticaux (Xagvl, Xagvr, Xaghl, Xaghr) de la carrosserie sur les essieux avant et arrière de la carrosserie) sont ainsi reconstruits. Sur la base de ces mouvements propres, les déplacements verticaux de la carrosserie aux points d'attache des systèmes de suspension sur la carrosserie sont déterminés et compensés de manière connue par des ajustements des systèmes de suspension. On peut ainsi minimiser de manière appropriée les mouvements propres de la carrosserie du véhicule par pondération.

Title: Rotary body.
Inventor: VITS REINHARD
IPC: F27B7/22
Filed: 1992-02-01
Abstract: Rotary bodies, for example rotary tubes with ring bearings, present the problem of linking the rings (3, 4), that may also act as driving elements, to the tubular body (2) in such a way that variations in diameter of the tubular body due to thermal expansion are reliably neutralized. Using elastic support elements has the inconvenient of imposing on the elastic elements the weight of the filled tube, so that they have only a limited service life because of the constant change of load. By means of holding shoes (13) that are capable of moving in the radial direction in the ring (3, 4) and that bear against the tubular body (2), radial pressing forces can be applied on the holding shoes (13) through clamping elements (17) mounted on the ring (3) and movable in the circumferential direction, when the clamping elements (17) are clamped against the ring (3) by prestressable elastic elements (21). The arrangement is self-centering and the elastic elements are subjected to no change of load even with variations in diameter of the tubular body (2).

Title: High-production rotary furnace steelmaking.
Inventor: SHERWOOD WILLIAM LYON
IPC: C21C5/56
Filed: 1992-11-12
Abstract: The invention is a process for steelmaking in a rotary furnace from a solid metallic charge adapted to realize greatly increased heat transfer and melting rates and thereby greater steel production. A hot liquid metal bath is maintained over the length of an oxy-fuel fired rotary furnace. Solid metallic scrap is continually introduced by way of a charge end opening into a melting zone, wherein the bath melting point temperature is depressed on the order of 300 degrees Celsius at the furnace charge end, by means of coincident additions of supplementary carbon into the melt. The effect is a multifold increase in temperature differential between the flame temperature and the temperatures of the furnace walls and charge, with a proportionate increase in the quantity of heat transferred. In order to maintain this depressed temperature, a corresponding increased quantity of cold solid scrap is required to be charged into the melt and advanced along the furnace, according a dramatic production rate increase in relation to the prior art. The preferred embodiment provides an intermediate annular dam which substantially confines unmelted solid charge to the melting zone, over which melted metal overflows into an all-liquid refining and temperature-composition adjustment zone preceding discharge, with overall firing and furnace interior gas flow countercurrent to the general charge movement, thus allowing the steel discharge temperature to be controlled independently of the heating rate. Other benefits include increased refractory life, less oxidation of charge and refractory constituents, and substantially less particulate and pollutants discharged in the process off-gas.

Abstract: Flat-panel type picture display device having a luminescent screen and a large number of electron propagation ducts operating by means of electron wall interaction. 
     At a given resolution hexagonal phosphor dot patterns in which dots are horizontally staggered generally produce fewer artefacts than in a 90° tilted orientation. An addressing system for withdrawing electrons from the propagation ducts and for directing them towards the luminescent screen is preferably formed as a multistepped structure with a preselection structure of rows of preselection electrodes and a fine-selection structure of rows of fine-selection electrodes. To interconnect the fine-selection electrodes in parallel in a minimal number of groups, it is advantageous when the fine-selection electrodes are arranged parallel to the preselection electrodes.
