Devices that measure the electron density in a body by means of radiation scattered from a narrow pencil beam of penetrating radiation directed through the body, produce defective images on reconstruction of the density distribution because of multiple scattering of radiation. This can of course be reduced by scattered ray diaphragms, but cannot be eliminated entirely. The invention therefore prov...

Decanter-type separating apparatus comprising within a rotatably mounted tapered and cylindrical barrel a solids-transporting screw rotating at a speed different from the barrel speed, the aforesaid apparatus being characterized by the screw having in an intensive clarification region a pitch substantially greater than used in the past, to stabilize the flow as far as possible and to obtain partic...

Decanter-type centrifuge separating apparatus, particularly of the countercurrent type, having a transporting screw-type rotor disposed within a rotating barrel to rotate at a differential speed, said machine being characterized by means acting on the liquid flow and/or on previously sedimented solids particles to obtain superior separation efficiencies.

PFBC power plant for burning fuel, primarily coal, in a fluidized bed of particulate material, at a pressure exceeding the atmospheric pressure. The plant comprises a bed vessel (12) which is divided into a first section (14) and a second section (16) by a vertical partition (17) which reaches up to the upper wall of the bed vessel (12) so as to form two separate freeboards (86 and 46, respectivel...

A method for effecting logging or servicing operations in a predetermined inclined or horizontal zone of a well, following an initial vertical portion thereof, comprising fastening a logging or servicing tool body at the end of a string of rods lowered into the well, said tool body being provided with an electric male connector, lowering at the end of an electric transmission cable, from the surfa...

A measuring device for a seismic profile within a well-bore includes resilient members such as springs which are flexible in at least two directions and are interposed between a geophone and a rigid arm connected to a measuring-tool body for applying the geophone against the wall of the well-bore during each detection of seismic waves generated at the ground surface. The elasticity of the resilien...

PURPOSE:To male high frequency transmittable at a low loss by forming a superconductive film of ceramics on both inner and outer conductors of a coaxial cable. CONSTITUTION:A superconductive coaxial cable C is provided with each of superconductive films 3, 4 consisting of optional material among ceramics superconductive materials, on an outer circumferential surface of its inner conductor 1 and an...

PURPOSE:To secure such a high temperature superconductor that is able to be rolled into a coil form by installing a normal conductive covered layer which covers a fine powder burned hot superconductive core. CONSTITUTION:A fused covering metal 1 of a normal conductor serving as a covering material for a superconductor is pressurized and sprayed out of an injection port 2 of a vessel tip. In this c...

PURPOSE:To prevent an internal stress from occurring as well as to make improvements in the superconductive characteristic of a wire rod by performing heat treatment as adding almost equal pressure to each surface of a section rectangular linear body. CONSTITUTION:Oxide superconductive powder or mixed powder turning to an oxide superconductor by heating is filled up in a pipe material consisting o...

PURPOSE:To prevent any void between a metal covered pipe and an oxide superconductor from occurring as well as to secure an excellent superconductive characteristic by performing heat treatment in a pressure atmosphere. CONSTITUTION:Oxide superconductor powder or mixed powder turning to an oxide superconductor by heating is filled up in a pipe material consisting of a normal conductive metal, and ...

Powdered psyllium seek husks are rendered rapidly and uniformly dispersible in water by admixing a solvent selected from the group consisting of benzyl alcohol, propylene glycol, triacetin and mixtures thereof with powdered psyllium seed husks.

In the process for preparing dental materials which contain, as essential constituents, a liquid, organic, polymerisable binding agent and a finely divided filler, such a filler is used which consists to 70 to 95% by weight of particles having a granule size of 0.7 to 25 microns and 30 to 5% by weight of particles having a granule size of 0.2 to 0.7 microns. The dental materials are particularly w...

Bonding to calcified tissues, including human teeth, tooth dentine and bone, is achieved through the medium of crystal growth adhered to the tissue. The crystals preferably comprise gypsum crystals which are formed by contacting the tissue surface with a mildly acidic solution containing sulphate ions.

A dispersion type electroluminescent element comprising dielectric, which is liquid at -20 DEG to +60 DEG C. and has a dielectric constant of 30-80, a gelling agent, and an electroluminescent phosphor, when used as an electroluminescent layer, has a practical brightness, which is never lowered for a long time, and has less disturbance to the electroluminescent surface.

PURPOSE:To uniformly and completely thin the dielectric layer of a capacitor and to easily damage a dielectric by constituting the capacitor of a tag of the burr of a metal foil for an electric circuit, a metal foil for an electrode and a bonding agent layer therebetween. CONSTITUTION:A needle is used from the aluminum foil 2 side of the capacitor part 21 of a circuit substrate on which an etching...

A coder assembles bursts of blocks of image data (eg transform coded coefficients) and associated overhead data into a sequence of data which are then transmitted. Both the transform coded coefficients and the overhead data are initially stored in separate FIFO memory stores (21)(22). The blocks of transform coded coefficients have a 'last coefficient' flag accompanying the last coefficient, and t...
