Patent EP-0286477-A1 (EP)
Inventor: HENNEGRAVE JEAN-PIERRE
IPC: B01D24/20
Filed: 1988-03-15
Abstract: According to the invention, there are provided: - downstream of the filter tank (1), a double-acting adjustable-flow controlled valve (6) capable of creating a variable pressure drop in the filtered water exit conduit of the tank, - at the surface of the volume of water in the tank, a detector sensor (E1) comprising an electrode sensitive to the presence or absence of liquid at a predetermined set level, producing a signal representative of the water level in the tank, and - means (8, 100) of incremental control of the valve, operating in response to the signal produced by the sensor, capable of opening the valve by successive pulses until the emergence of the initially immersed electrode is obtained, or of closing it again by successive pulses until the immersion of the initially emerged electrode is obtained, so as to vary the pressure drop created by the valve downstream of the tank in the opposite direction to the variation in pressure drop of the filter bed accompanying a variation in the water level in the tank. As a result, the rate of filtration of the water delivered to the tank remains substantially constant. <IMAGE>

Inventor: LUMBROSO DANIEL
IPC: C10B33/00
Filed: 1988-05-10
Abstract: The invention relates to a process for coking hydrocarbon charges such as heavy distillation products or residues. It relates more particularly to the subsequent stage of recovery of the coke after it has been deposited in the coking reactor. This process consists in lowering into the reactor (1), from a drum (3) onto which it is wound, a flexible tube (14) of sufficient mechanical strength whose lower end is provided with means for ejecting water (17) downwards and/or sideways and whose descent is controlled by the unwinding from the drum. Water under pressure is passed through the tube and through the means of ejection in the direction of the coke and the pieces of coke which are detached are removed (20). The drum can be moved sideways so as to come into position above each of the reactors in turn when two or more reactors are employed. <IMAGE>

Title: High speed raster image processor.
Inventor: MENENDEZ JUAN GERARDO
IPC: G06F13/36
Filed: 1988-02-16
Abstract: A pipe-lined raster image processor (RIP) contains a bus (80) and connected thereto a number of separate image processing components (30, 50, 60, 70) capable of undertaking a respective image processing task substantially in parallel with those undertaken by other of these image processing components. In addition, an arbiter (40) is also connected to the bus. The arbiter receives a request from anyone of the image processing components for service from another one of the image processing components. Then, depending upon the availability of the bus and the destination component, the arbiter defines a data path over said bus between the source and destination components, and thereafter initiates an information transfer over the bus and between these components. Once this transfer is complete, the destination component is then able to undertake its respective image processing task substantially independent of the tasks undertaken by both the arbiter and the source component. At this point, both the arbiter and the source component are free to perform other image processing tasks while the destination component is performing its respective task.

Abstract: PCT No. PCT/FI88/00050 Sec. 371 Date Nov. 28, 1989 Sec. 102(e) Date Nov. 28, 1989 PCT Filed Apr. 5, 1988 PCT Pub. No. WO88/07980 PCT Pub. Date Oct. 20, 1988.In a fibrillation device for the manufacture of mineral wool, the mineral wool melt runs down onto the peripehral surface of a spinning wheel from which it is thrown to further spinning wheels. The melt is thrown out as fibres which are subjected to a strong blast of air. The stream of air is conducted through an air gap having oblique guide vanes in order to impart to the stream of fibres an axial and a tangential velocity component. The air gap is formed to impart to the stream of fibres a radial velocity component directed outwards in addition to the tangential velocity component in the direction of rotation. Therefore, the air stream meets the peripheral surface of the spinning wheel at an oblique angle and forms a conically shaped curtain around the peripheral surface of each spinning wheel.

Abstract: An electropneumatic rotary actuator (10) has proportional fluid valving (44) providing introduction and exhaust of pressurized fluid to and from a working chamber (45) of the actuator. By control of the admission angle and venting angle of the fluid pressure and flow with respect to top dead center and bottom dead center of a working piston (28) of the actuator both the torque level and gas consump­tion rates of the actuator may be controlled. Further by modulating the average working fluid pressure within the actuator the stiffness or resistance to backdriving of the actuator may be controlled. A proportional linear elec­trical solenoid (48-86) is disclosed and employed in the actuator of the present invention to drive a double-acting closed-centered valve device (88-116). Because of its lightweight, relatively simplicity, high stiffness to backdriving, and relatively low gas consumption rate, the present actuator is expected to find application in airborne vehicles.

Abstract: Die Schaltungsanordnung zur Selbsterregung eines mechanischen Schwingsystems (10) zu Eigenresonanzschwingungen enthält ein elektromechanisches Wandlersystem (20), das im Rückkopplungskreis einer elektronischen Verstärkerschaltung (30) angeordnet ist, so daß es durch die Ausgangswechselspannung der Verstärkerschaltung (30) zu mechanischen Schwingungen angeregt wird und zum Eingang der Verstärkerschaltung (30) eine Wechselspannung mit der Frequenz der mechanischen Schwingungen liefert. Die Verstärkerschaltung (30) weist eine nichtlineare Verstärkungskennlinie auf, die bei kleinen Werten des Eingangssignals eine größere Verstärkung als bei größeren Werten des Eingangssignals ergibt. Dadurch ist ein sicheres Anschwingen auch unter ungünstigen Betriebsbedingungen gewährleistet, während andererseits die Gefahr von Fehlanzeigen des Schwingungszustands, beispielsweise infolge von Fremdvibrationen, verringert ist.

IPC: G01H9/00
Filed: 1989-06-29
Abstract: Since the models for calculating wave propagation in SAW components do not take account of all the physical effects, deviations frequently arise between the realised and the desired module performance. In order to improve said models, it is therefore necessary to image the wave field in the component in a phase-sensitive fashion or to measure with spatial resolution the parameters characterising the elastic wave. It is proposed to determine quantitively the change, caused by the elastic volume waves or shear waves, in the double refraction of the substrate with the aid of a polarised laser beam. As radiation source, use is made in particular of a mode-coupled Nd:YAG laser with a downstream pulse compressor, and this provides the measurement method with a bandwidth located in the GHz range. <IMAGE>

Abstract: A current sensor including a magnetic sense element having a core which undergoes cyclic saturation. By driving the ferromagnetic core cyclically into forward and reverse saturation the transformer operates in a near zero flux mode. The sensing apparatus may include circuitry for separating the sensed current component from the magnetising current component in the secondary winding of the magnetic sense element. The apparatus may also include correction circuitry to cancel the effects of ripple current on the output due to both the magnetisation current and errors due to the presence of the ripple cancellation circuitry itself. The circuit may also be provided with decoupling means to cancel the effect of voltages reflected back into the primary circuit. 
     Such a sensing apparatus provides electrical isolation between the primary circuit and the sensing circuit, has good bandwidth, and is insensitive to temperature, temperature gradient, mechanical forces, aging (creep) and noise.
