Abstract: A device for controlling the engine speed in idling of an internal combustion engine to which so-called "modern control theory" is applied, and is directed to improve drastically the converging speed to a target number of revolution. The present invention updates the values of state variables even in an open-loop control state, to calculate initial values at the time of shift to feedback control. When a change of state of an external load is detected, an integration value is corrected in a feed-forward manner before it is limited to a predetermined range integration value limiting means in accordance with such a change of state. The present invention divides dynamic model for a control system into a dead time portion and a portion after the dead time portion, and identifies the dynamic model by a discrete system for each of these portions to configurate it.

Title: Particle concentrator.
Inventor: PACE DAN R
IPC: B04B1/08
Filed: 1991-04-03
Abstract: Upper and lower bowl members are mounted on a common linear cylindrical member and a relief valve provides controlled gas pressure within a centrifuge housing in a low speed decanting centrifuge for separating relatively large particulate material (e.g. yeast) from a feedstock. The centrifuge may be clamped to a container and a pressure differential is created between the centrifuge housing and the container to, in turn, force feedstock upwardly into the lower bowl of the centrifuge. A stack of frustonconical discs carry supernatant downwardly and inwardly for vertical transfer to a discharge chamber, Particulate matter is centrifugally discharged continuously between engageable surfaces of the lower bowl member and the upper bowl member. Hydraulic forces generated within the bowl are isolated from a thrust bearing supporting the bowl and transferring drive forces to an intake. The invention further provides for separately collecting and controlling discharge from the centrifuge housing, whereby gas pressure within the housing may be increased further to partially counterbalance hydrostatic forces within the bowls, thus permitting bowl members of low material strength to be used in relatively high speed separation to improve processing capability.

Title: Process and device for image signal recording or reproduction.
Inventor: PLANTHOLT MARTIN
IPC: H04N9/83
Filed: 1991-04-10
Abstract: Letter-box television signals of 16:9 image format compatible with 4:3 receivers may contain, in the two edge strips above and below the active image, additional information needed by a 16:9 receiver in order to reproduce an image with a resolution close to that of the source signal. This additional information may be modulated on the colour carrier and therefore become unusable when recorded on a video recorder (approx. 600 kHz chrominance bandwidth). If the additional information is recorded in the edge strip lines, e.g. in S-VHS video recorders in combination with corresponding switchovers via the luminance channel, the entire bandwidth (about 5 MHz) of the additional information is retained.

Title: Iontophoretic drug delivery system with two-stage delivery profile.
Inventor: SORENSON PAUL D
IPC: A61N1/32
Filed: 1991-03-22
Abstract: A two-stage iontophoretic drug delivery system provides that iontophoretic current is delivered at a first level for a first predetermined interval to rapidly introduce a therapeutic agent into the bloodstream and thereafter reduced to a second lower level to maintain a desired steady-state therapeutic level of the agent. One embodiment provides that the initial interval is maintained sufficiently long to provide a peak dosage, thereafter which the current is shut off to allow concentration of the agent to subside in the bloodstream, whereupon a maintenance level of iontophoretic current is initiated. Another embodiment provides that the patient may selectively initiate a brief interval of increased iontophoretic current level to attain a brief interval of increased dosage.

Abstract: PCT No. PCT/EP91/01021 Sec. 371 Date Apr. 6, 1993 Sec. 102(e) Date Apr. 6, 1993 PCT Filed Jun. 3, 1991 PCT Pub. No. WO92/03786 PCT Pub. Date Mar. 5, 1992.In an m-of-n computer system, timer signals (TA, TB, TC) are fed as interrupt requests (IA, IB, IC) to modules (BGA, BGB, BGC) allocated to the individual computers and from there to the majority elements (MA, MB, MC), which release appropriate interrupts (INT2A, INT2B, INT2C) to the corresponding computer when the m-of-n condition is adhered to. To be able to recognize, after one computer (for example MCA) has failed, when interrupt requests (IB) of another computer (for example MCB) fail to appear, each remaining operational computer (MCB, MCC) initiates troubleshoot testing programs in larger time intervals. This is achieved by performing OR-gating operations on certain timer signals. Switching through the interrupt requests via the majority elements requires much less time than does a corresponding software-comparison operation and results in only a very slight base load for the computer system during the processing of interrupts.

Abstract: Système de raisonnement qualitatif qui isole une panne de machine en générant une pluralité d'hypothèses en attente (108) qui présument la panne d'un ou de plusieurs composants de machine et en testant chacune de ces hypothèses en propageant des valeurs effectives pour les paramètres des machines par des équations de confluence pour l'hypothèse testée. Des variables associées à des hypothèses d'un modèle physique qualitatif sont groupées en variables de type I et en variables de type II et toute valeur possible mesurée pour une variable de type I est garantie en vue de rendre au moins une hypothèse inadéquate et certaines mais non toutes les valeurs possibles mesurées pour une variable de type II rendront au moins une hypothèse inadéquate. Une série de confluences est jugée inadaptée en déterminant qu'il n'existe aucune série de valeurs pouvant être assignée à toutes les variables inconnues des confluences qui résultent en une série adaptée de prédictions. La valeur d'une variable inconnue est déterminée en portant itérativement la variable à chacune de ses valeurs possibles et, pour chaque itération, en propageant les variables connues et la valeur de la variable inconnue dans des confluences du modèle. Un instanciateur de modèle convertit l'entrée utilisateur de la station de travail informatique en information utilisable sur le modèle et fournit d'autres optimisations qui réduisent le nombre de confluences et de variables dudit modèle.

Abstract: A rotary dry shaver includes an outer shearing foil (40) supported on a head frame (30) and an inner cutter holder (61) having a center axis and carrying a plurality of inner blades (62) in hair shearing engagement with the outer shearing foil (40). The inner cutter holder (61) is operatively connected to a rotary drive shaft (13) of an electric motor so as to be driven thereby to rotate about the center axis. The outer shearing foil (40) is held movable in the direction of the center axis relative to the head frame (30), while the inner cutter holder (61) is movable along the center axis relative to the rotary drive shaft (13) so as to be floatingly supported thereby. The dry shaver is characterized in that the outer shearing foil (40) is connected to the inner cutter holder (61) by means of a pin (43) extending along the center axis such that the outer shearing foil (40) and the inner cutter holder (61) are movable together along the center axis relative to the head frame (30) as well as the rotary drive shaft (13). Thereby contact pressure between the inner blades (62) and the outer shearing foil (40) can be kept substantially at a constant level irrespective of the relative movement of the outer shearing foil (40) to the head frame (30).
