PURPOSE:To prevent a powerless feeling from being given to power performance by suppressing a decrease amount of engine output, decreased by an output decreasing means in speed change action, to a less degree when an automatic transmission is operated in a power mode than when an economy mode is selected. CONSTITUTION:When an automatic transmission 12 performs speed change action, a showing signal...

A curved edge (24) (25) (26) on a lens (21) is formed by directing a laser beam (23) onto the lens adjacent its edge and causing relative movement between the laser beam and contact lens whereby a curved surface is formed on the edge of the lens by the removal of material therefrom through ablative photodecomposition.

The invention provides a method and apparatus for welding together two metal workpieces, at least one of which has thereon a coating material which enters a fluid or visco-elastic phase at a temperature below the melting temperature of the workpieces, the method comprising the steps of subjecting the workpieces to a preliminary preparative treatment at a zone to be welded and thereafter applying (...

A Fourier Transform Ultra-Violet visible (FT/UV-Vis) instrument has no more than one moving part. It is adaptable inter alia to monitor fast reactions or to use in evanescent wave Attenuated Total Reflection Spectroscopy in the UV-Vis region. By using a Fourier transform generator the instrument has high sensitivity. Alternatively, a Hadamard transform generator may be used where the instrument ha...

An x-ray diagnostics installation for subtraction angiography has an image memory connected to an output of an x-ray image intensifier video chain which has a number of addresses for storing individual x-ray video signals obtained during a dynamic body cycle of a patient under observation. A differencing unit receives stored signals from the image memory as well as current video signals and substr...

A continuous marine pipe laying system utilizes two rollers to overbend and straighten pipe as it is unwound from a reel. A support arm is pivotally connected to the axis of rotation of said reel and first and second roller arms are pivotally connected to the support arm at a point spaced from said axis of rotation. During use, the first roller is positioned at a point adjacent the pipe substantia...

1. Apparatus for the centrifugal separation of a mixture including at least one gaseous phase, this apparatus comprising, in a fixed enclosure (21), a rotating element constituted by a treatment rotor (24) incorporating perforated (48) discs (49) offset angularly one from the other, upstream by a rotary distributor (49.1) and downstream by a ventilator (36), the mixture to be treated being directe...

In a solid bowl centrifuge, in particular for separating media with different density or their mixtures and/or suspensions, which are difficult to separate into a comparatively lighter and at least one heavier phase, having a drum which is rotatably mounted on a shaft and forms in itself a settling basin, and having elements for feeding in the media to be separated and for discharging the separate...

Bei einem computertomographen der dritten oder vierten Generation soll eine einfache und exakte erfassung der Streustrahlung mit Hilfe von detektorelementen (16, 17 usw.) für diese Streustrahlung erfolgen, wobei die Eichung dieser Detektorelemente (16, 17, usw.) in einfacher Weise möglich sein soll. Der gesamte Strahlenempfänger mit zwei parallelen Detektorreihen (8, 15) für die primäre Röntgenstr...

Mit einem Reaktor zur Durchführung katalytischer Gasreaktionen mit einer Mehrzahl von über der Höhe des Reaktors angeordneten, in das Katalysatorbett mündenden Kaltgaszuführungen soll eine Lösung geschaffen werden, welche bei möglichst geringem Raumbedarf eine befriedigende Vermischung der zugeführten Kaltgase mit den heißen Reaktionsgasen ermöglicht, um über der Höhe des Reaktors ein möglichst gl...

The present invention provides a cassette loading device for an image forming apparatus including a sheet feeding portion within which a cassette (3) for accommodating sheets is loaded, and a sheet feeding means arranged in the sheet feeding portion and adapted to feed the sheet from the cassette (3) loaded within the sheet feeding portion. The cassette loading device comprises a guide means for g...

In a computer tomography device comprising an X-ray tube having an elongate anode across which a focus can be displaced, a tomosynthetic scanogram can be formed by correctly shifting the profiles measured in the various source positions with respect to one another, followed by superposition. Parts of the object which are situated in a selected layer are thus emphasized in an image, parts of the ob...

The invention provides a method and apparatus for welding together two metal workpieces, at least one of which has thereon a coating material which enters a fluid or visco-elastic phase at a temperature below the melting temperature of the workpieces, the method comprising the steps of subjecting the workpieces to a preliminary preparative treatment at a zone to be welded and thereafter applying (...

The present invention provides a process for the deionization of aqueous ion containing solutions comprising: circulating an aqueous ion-containing solution within a shell of a deionizing device having an inlet and an outlet port; simultaneously passing an aqueous acid solution through an assembly of cation-exchange membranes at least partly disposed within the shell; and simultaneously passing an...

Point-bonding and water-jet-softening of a sheet of flash-spun polyethylene plexifilamentary film-fibril strands provide a nonwoven fabric that is particularly suited for dyeing and use in disposable protective garments. Garments made with the nonwoven fabric are comfortable and provide a good protection against particulate matter, such as air-borne asbestos particles.
