A nuclear magnetic resonance tomography apparatus generates a tomographic image substantially free from artifacts caused by body movement, such as respiration, during acquisition of the tomography signals. The tomography signals are acquired and stored in the form of Fourier lines in an image matrix. For reducing image artifacts, a control unit is provided for controlling entry of the acquired tom...

A drop-catching structure for use in a liquid jet printing apparatus of the type which generates a linear array of closely spaced (i.e., high density) droplet streams from an orifice plate. The droplets are deflected from a normal droplet path towards a catching structure, the preferred embodiment of which includes an upper first planar surface substantially parallel to the droplet path, an interm...

A probe assembly for use in testing an integrated circuit embodied in an integrated circuit chip in wafer form, comprises a stiff support member formed with an aperture, and a membrane. Both the support member and the membrane comprise dielectric material and portions of conductive material supported by the dielectric material in electrically-insulated relationship. The portions of conductive mate...

A method of separating or recovering material from a liquid, the material being in the form of agglomerates or being immobilised on a support. The liquid is held in a vessel having at least one outlet aperture (3a) of a size less than said agglomerates or said supports, removing the liquid, causing the material to be de-agglomerated or de-immobilised, and then causing the material to pass through ...

A dot printer (1) is disclosed for effecting the print by ejecting ink in dots such that under the normal print speed mode in which the dot density is high, a standard amount of ink is ejected per dot, and under the high print speed mode, or draft mode, in which the dot density is low, a greater amount of ink is ejected per dot.

Process for in-situ detoxification of groundwater contaminated by polluting compounds such as nitrates, pesticides, chlorinated solvents, pyralenes, mineral oils, various anthropogenic organochemical compounds, characterised by confinement in a part of the aquifer, by production of hydraulic gradients, of a reaction zone (AB) within which there are monitored at the same time: the presence of micro...

The heat exchanger has parallel tubes forming a tube bundle having a longitudinal axis. The tubes are arranged in parallel tube rows with regular straight lanes being defined through the tube bundle transverse to the direction of the tube rows. Lanes are defined through the tube bundle at an angle with respect to the direction of the tube rows and a second plurality of lanes being defined through ...

Hydraulic high density cement slurry, especially for cementation of oil/gas-wells. The slurry contains 30-45 weight % microsilica based on the cement weight and water to a density of 1.9-3.5 g/cm3. If desired there can be added dispersant, retarder and weighting agent. Microsilica acts as a fluid-loss preventing agent. The addition of microsilica prevents strength retrogression at temperatures abo...

PURPOSE:To automatically perform annealing of a formed product and then separate it by such an arrangement wherein a formed product is grasped by the top end of a loading arm and then its runner part is grasped by a grasping device and then the product is sent to the position of annealing and to the position where its gate part is cut by means of the grasping device. CONSTITUTION:When the metal mo...

A cementitious composition comprising hydraulic cement, not more than 25% of water by weight of the composition, and water soluble or dispersible (co)polymer in a proportion of 1 to 15% by weight of the hydraulic cement in the composition, the cement and (co)polymer being selected such that a test composition comprising 100 parts by weight of cement, 5 parts by weight of (co)polymer, and 16 parts ...

A power control circuit, such as a lamp dimmer, has a load connected in series with a bridge rectifier (GL) (Fig 1), across a supply, FET T1 connects across a diagonal of the bridge (FL) and turned on at each zero-crossing of the supply and turned off by a monostable M at an adjustable time in each supply half-cycle, and circuit elements R1, R2 C1, C2 which cause the FET T1 to turn off gradually w...

Apparatus for separating solid particles from a liquid suspension and/or purification or leaching of solid particles, consisting of a cylindrical column (1) which near one end is provided with a rotatable scraper (4) for the disintegration of a washed compacted bed (2), an inlet (27) for wash liquid and an outlet (16) for the disintegrated particles, and contains near the opposite end of the colum...

Bei der Herstellung innen glattwandiger, außen jedoch Umfangsrippen aufweisender Kunststoffrohre aus extrudierbarem, insbesondere thermoplastischen Kunststoff wie PVC wird eine gute Füllung der zur Bildung der Rippen vorgesehenen Hohlräume in der wandernden Hohlform dadurch erreicht, daß diese Rippen zuerst im Abstand von der Trennebene der wandernden Hohlform und zuletzt im Bereich dieser Trenneb...

Die Erfindung betrifft Wärmedämmformkörper (6) mit Umhüllung, die dadurch gekennzeichnet sind, daß ein Formling aus einem mit einer tiefziehfähigen Umhüllung (4,5) versehenen Grundkörper (3) auf Basis von verpreßtem, mikroporösem Wärmedämmstoff, wobei der Druck innerhalb der Umhüllung auf bis zu 10<-><6> bar vermindert ist, bei Drücken im Bereich von 1 t/m² bis 1000 t/m² geprägt wird.; The inventi...

The invention covers cement slurries for the cementing of oil wells or similar, with good fluid-loss control, characterized by the fact that their mix fluid is an oil-in-water emulsion stabilized by at least one surface-active agent.

Plasterboard made of calcium sulphate hemihydrate and fillers contains, in the gypsum core, from 15 to 50% by weight, based on the gypsum, of ground limestone, anhydrite and/or sand as inert filler, with the particle size distribution of the filler, whose particle size ranges from 0 to 1.5 mm, corresponding to the Fuller curve.

Solvent-free alkyl trialkoxy-silanes whose alkyl groups have 2 to 8 carbon atoms and whose alkoxy groups have 1 or 2 carbon atoms are used for the in-depth hydrophobic impregnation of concrete. Propyl and isobutyl trialkoxy-silanes display an especially deeply penetrating hydrophobizing action which is greater than that of solutions of these silanes.
