A method for the gaseous reduction of particulate ores to metals in a moving bed, vertical shaft reactor using a reducing gas externally supplied from a solid or liquid fossil fuel gasification unit. The reducing gas is reformed in a reforming zone located within the reactor and treated prior to injection into the reduction zone of the reactor. A portion of the reducing gas produced in a coal gasi...

An apparatus and method for the measuring the transverse dimensions of a hole such as in an oil well including a sonde on which an electro-acoustic transducer is mounted in an offcentered position in relation to the axis of the sonde. This transducer has two opposite active faces so as to simultaneously transmit acoustic pulses in diametrically opposite diections from the sonde. When the sonde is ...

The invention relates to a sound-damping element (1), in the outer layers (3, 5) of which U-profiles (6-11) are inserted. The U-profiles (6-11), preferably made of steel, increase the sound-damping value of the element from 39 dB to 44 dB. Gluing the U-profiles (6-11) into the outer layers (3, 5) of the element moreover ensures better rigidity of the element (1).

The invention relates to a device for detecting shorted turns in rotors of collector machines. In spite of careful fabrication, there is always a risk that shorted turns occur in the rotor. It is therefore the object of the invention to create a protection for the motor mentioned initially, which detects the shorted turns in the rotor during operation and switches off the motor as quickly as possi...

PURPOSE:To determine the line width of a printed wiring pattern having optional lattice line pitch by deciding on large, intermediate, or small line width of a line picture which is drawn through intersections of lattice lines with the optional equal pitch at every intersection of lattice lines. CONSTITUTION:A determining circuit 3 makes a raster scan on divided pictures (rectangular picture segme...

A process for biotreatment of a liquid mass, through contact with a biomass is characterized by the fact that the bioreactor in which the process is performed comprises a container holding a bed of biomass, means of supporting this bed, means of admitting the liquid mass for treatment, means of recirculating the liquid mass during treatment, means of extracting at least part of the treated liquid,...

The invention relates to a micro-encapsulation housing for electronic circuits and, in particular, to the cap (base), consisting of a ceramic material, of such a housing. Electronic circuits frequently contain coupling or decoupling capacitors which cannot be integrated on a semiconductor platelet (substrate) and which, as a consequence of this fact, occupy a larger area than an integrated circuit...

A bottle-shaped container of saturated polyester having frosted or ground surface is manufactured by the steps of heating the outer layer portion of the injection-molded preformed piece to thereby crystallize the outer layer portion to opacify in white, and blow-molding the preformed piece in a blowing mold having at least part of its inner surface formed with rough surface sandblasted in advance ...

A disposable container for forming the end wall of the open end of a barrel of a syringe and for being retained thereon by the resilient interaction of a surface of the barrel and the resilient periphery of a circumferential flange at the intersection of a substantially rigid first wall portion and a flexible second wall portion of the container. Preferably the resilient periphery flexes when pres...
