Patent EP-0498098-A1 (EP)
Inventor: IBBOTT JACK KENNETH
IPC: C02F1/46
Filed: 1991-04-30
Abstract: The present invention relates to a method and apparatus for treating electrically conductive fluid. In one embodiment, positive (1) and negative (2) electrodes of electrically conductive materials having different electrochemical potentials are spaced apart. At least one of the electrodes has a covering of electrically insulative material (3,4) extending substantially therearound. Thus, the only electroconductlve connection that develops an electrochemical potential between the electrodes is established by a capacitive effect through the fluid to be treated, which fluid is passed between the electrodes (1,2). In another embodiment of the present invention, first and second electrodes (6,7) of electrically conductive material are spaced from one another, and at least one of the electrodes is provided with a covering of electrically insulative material (8,9) extending substantially therearound. An external source of energy (12) is connected to the first and second electrodes. Accordingly, when a body of electrically conductive fluid to be treated is interposed between the electrodes, an electroconductive connection between the electrodes is established through the body of fluid by a capacitive effect and the fluid is ionized. In each case, by providing at least one of the electrodes (1,2; 6,7) with a covering of electrically insulative material (3,4; 8,9), current flow between the electrodes is inhibited which contributes to the efficiency of the apparatus in ionizing fluid, even fluid having a high degree of electroconductive capability.

Abstract: In data transmission and storage using encoding through finite-state machines, the feedback link that updates each finite-state machine after each encoding step presents a bottleneck for a high speed implementation. The invention solves this problem for a class of finite-state machines that includes the encoder for the known 8B/10B Widmer-Franaszek code. The architecture consists of parallel finite-state units that are pipelined to run at a relatively low clock frequency. State updating is broken down into a feedforward part and a feedback part. In the feedback part, the state of each unit can be updated with a single operation. This allows efficient implementation of the finite-state encoder for practically any data rate just by appropriate pipelining and parallel processing.

Abstract: Pour le traitement de données relatives à des images devant être transmises, les images originales sont décomposées en zones de trames, et des données codées de transformation sont traitées et/ou calculées en vecteurs de déplacement, en mode trames, en fonction d'un critère de modification. Pour la transmission, les données codées de transformation et/ou les vecteurs de déplacement correspondant à une image originale sur deux sont établis uniquement pour quelques trames, pour lesquelles les modifications sont importantes. Pour la reconstitution, côté réception, des images interpolées sont formées, images dans lesquelles on insère les trames pour lesquelles les données codées de transformation et/ou les vecteurs de déplacement ont été établis. Le procédé selon l'invention convient notamment pour la transmission d'images prises avec des caméras utilisées sans pied. Il ne se produit ni structure de blocs gênantes, ni mouvements saccadés.

Abstract: Cloned recombinant or synthetic DNA sequences related to the pathology of Alzheimer's disease are injected into fertilized mouse eggs. The injected eggs are implanted in pseudo pregnant females and are grown to term to provide transgenic mice whose cells express proteins related to the pathology of Alzheimer's disease. The injected sequences are constructed having promoter sequences connected so as to express the desired protein in brain tissues of the transgenic mouse. The proteins which are preferably ubiquitously expressed include (1)  beta -amyloid core precursor proteins; and (2)  beta -amyloid related precursor proteins; and (3) serine protease inhibitor. The transgenic mice provide useful models for studying compounds being tested for their usefulness in treating Alzheimer's disease, and for studying the in vivo interrelationships of these proteins to each other.

Abstract: In an automotive vehicle steering unit, designed according to the invention, with an axially adjustable steering column (2) bearing a steering wheel (4), in the engaged position said steering column is held in a force-closed fashion by a clamping element (30) of a steering column receptacle, on which element a safety device acts by means of a cable (43) which introduces a tractive force (F) directed essentially in the axial direction of the steering column, in order in the event of an accident to move the steering wheel (4) away from the region of impact with the driver's head. In this arrangement, the clamping element (30) embraces the steering column (2) in such a way that when the safety device becomes effective the clamping element (30) is tilted and in the process there is a sharp rise in the force closure which is sufficient at least to transmit the cable tractive force (F). Consequently, despite the structurally simple design, when the safety device becomes effective conversion into an axial displacement of the steering column (2) is possible without dead travel and thus immediately. <IMAGE>

The heating element (28) has two terminal wires (40) which extend radially outward parallel to each other from either a common end portion or two separate end portions (30) of the heating element. After the heating element (28) is wound in the spiral channel (18) in the nozzle body (10), forward and rear collar portions (46,60) are mounted around the nozzle body (10) to form a radial slot or opening (72) between them through which the end portion or portions (30) of the heating element project. A stud portion (84) is mounted to extend radially outward from the slot (72) with a single bore or two parallel bores (86) through which the end portion or portions (30) extend. These components are then brazed together in a vacuum furnace to form a strong integral structure with the end portion or portions (30) of the heating element (28) secured in place. In one embodiment, a spacer portion (152) having two parallel bores (156) is mounted with ceramic paste to the stud portion (142). The two terminal wires (40) extend out through the bores for connection in a threaded cap (168) to a pair of external lead wires (128).
