Patent EP-0254725-A1 (EP)
Inventor: SCHMITT MANFRED
IPC: F16K17/04
Filed: 1986-11-21
Abstract: La soupape ci-décrite est pourvue d'un disque de soupape (7) s'accouplant avec un siège de soupape (8), ledit disque portant une collerette de déflexion (12) à conicité interne, laquelle recouvre vers l'extérieur la section transversale du siège de soupape (8). Cette collerette de déflexion (12) facilite la course afin d'augmenter les forces qui agissent dans le sens d'ouverture de la soupape lors de la déflexion. La collerette de déflexion (12) comporte une partie (13) à conicité interne et une partie (14) à conicité externe, qui est approximativement identique au niveau de son angle de conicité mais qui fait saillie pour l'écoulement. Les deux parties coniques (13, 14) sont reliées l'une à l'autre au niveau de la région de transition par une partie médiane (15) qui assure une transition en douceur. On a observé qu'avec une configuration conique ininterrompue de la collerette de déflexion, la courbe caractéristique force/course présentait approximativement dans le premier tiers de la course une pente qui tend à réduire la puissance. La partie médiane (15) qui relie les deux parties coniques (13, 14) est disposée dans la région conique où cette baisse de puissance se produirait dans le cas d'une collerette de déflexion d'une conicité ininterrompue. Par suite, la section transversale d'écoulement libre subit une réduction de l'accroissement de la section d'écoulement dans la région de la partie médiane (15).

Patent EP-0277248-A1 (EP)
Inventor: KOBAYASHI KAZUO
IPC: B21B13/18
Filed: 1987-07-31
Abstract: Multistage rolling mill having a pair of upper and lower work rools, a pair of upper and lower backup rolls, and an intermediate roll provided between at least one of the work rolls and the associated backup roll, all of which rolls are arranged in a substantially vertical direction; intermediate rollers supporting the work rolls in the direction of a path of a work; and support rollers supporting the intermediate rollers, characterized in that each of the support rollers consists of a plurality of axially arranged divided rollers which are staggered in succession in the axial direction of the support roller so that the axis of each of the divided rollers is spaced vertically from that of the adjacent divided roller. Since the work rolls in the rolling mill are supported on the support rollers of the above-described construction, a space can be secured between each of the support rollers and the associated backup roll, which supports the work roll in a substantially vertical direction, or the associated intermediate roll. Accordingly, the support rollers and backup rolls or intermediate rolls do not contact each other, so that the diameter of the work rolls can be reduced. Moreover, since each intermediate roller which supports the associated work roll directly is supported reliably by two divided rollers the axes of which are spaced from each other, the work roll can be supported stably. This enables a highly accurate and stable rolling operation.

Abstract: An alkylation-transalkylation process for the selective production of a monoalkylated aromatic compound is disclosed which maximizes the production of desirable monoalkylaromatic compounds, while limiting transalkylation catalyst deactivation. The process entails the combination of an alkylation reaction step, a first separation step, a second separation step, and a transalkylation reaction step wherein the alkylation catalyst is comprised of phosphoric acid material and the transalkylation catalyst is comprised of a crystalline aluminosilicate material. A key feature involves reducing transalkylation catalyst deactivation by transalkylating only dialkylated aromatic compounds.

IPC: G01R33/025
Filed: 1988-11-15
Abstract: The invention relates to a method for the suppression of the effect of strong magnetic interference fields which may occur during the sensing of magnetic markings (9) provided on a web or other carrier (8) whose magnetic fields are small in relation to the interference fields. 
     The method is based on two equal magnetic sensors (1,6) being fitted adjoining the carrier (8) of the magnetic markings (9) which are to be detected but at a slightly unequal distance from the carrier (8). The carrier (8) is led past the sensors (1,6) which each detect the markings (9) but with differently strong detecting signals, since they are located at unequal distances from the carrier (8). The interference fields, on the other hand, are so strong and their sources so remote that the detection signal from both the sensors (1, 6) will be the same. The said sensors (1, 6) are coupled in phase opposition, whereby the detection signals from the interference fields wholly extinguish each other whilst the detection signals from the magnetic markings (9) certainly are subtracted from each other, but result in a residual signal which can be amplified and made use of for the control of working operations on the carrier (8).

Abstract: A device for controlling a turbocharger with an electric rotary machine detects, at all times, the rota­tional speed of the engine on a motor vehicle and the amount of depression of the accelerator pedal while the motor vehi­cle is running, to confirm present running conditions of the motor vehicle. A required boost pressure which is required under the confirmed running conditions is determined, and if the required boost pressure is higher than the boost pres­sure produced from the turbocharger by the energy of exhaust gases emitted from the engine and corresponding to the rota­tional speed of the engine, the controlling device drives the electric rotary machine coupled to the rotatable shaft of the turbocharger as a motor to increase the speed of rotation of the turbocharger for a quick buildup of the boost pressure.
