Apparatus and a method for removing suspended particles from water in a circular tank having a distribution and flocculation chamber immersed in the tank of water and carried circularly around the tank by a carriage. Flocculating material and inlet water are introduced into the body of water from the moving flocculating chamber at the same rate as clarified water is discharged through a filter sub...

1533803 Converter steelmaking INSTITUT DE RECHERCHES DE LA SIDERURGIE FRANCAISE 30 Aug 1977 [30 Aug 1976] 36238/77 Heading C7D Iron is refined in a bottom blown converter by injecting a strongly oxidizing gas e.g. pure oxygen, through the central passage of a double-channel tuyere, and injecting liquid oxygen through the annular outer channel. The amount of liquid oxygen may be 0À2-0À5 kg/Nm3<...

PURPOSE:To accurately draw out a web by starting draw-out means at a low speed, and then switching the draw-out means to the steady high-speed operation in case of intermittently drawing out a designated length of a web wound round an original cloth roll by the draw-out means, and again switching the draw-out means to the low speed operation at the time of stopping the draw-out means. CONSTITUTION...

The invention relates to a method of producing a wound compress comprising a cottonwool filling in a gauze cover which is made with three layers on the outer sides of the compress due to the special production method (Fig. 4a).

In a process for producing sponge iron by continuous reduction of iron oxides in a blast-furnace (shaft furnace), the reaction gas is removed from a blast-furnace, essentially the entire CO2 and H2O is removed from this reaction gas, and the reaction gas is divided into at least two part-streams. One of these part-streams is fed to a gas generator which has a plasma burner and devices for injectin...

1. An electrically actuated solenoid magnet with a travel position detection, comprising a load winding (22), a soft magnetic armature guide part which projects axially past the load winding at one end, in which guide part an armature (10) is displaceably arranged, a nonmagnetic isolating joint (26) provided in the armature guide part (14) outside the load winding (22), a sensing coil (24) which s...

To unravel a terminal portion of a textile yarn, in particular in preparation for joining that yarn to another one by twisting their ends together, an extremity of the yarn is vibrated to loosen the fibers while a part of the yarn spaced from its end is held fast and the yarn extremity is combed or subjected to an aspirated air stream to remove loose fibers. In a preferred arrangement the air stre...

1-(N,N-disubstituted carbamoyl and thiocarbamoyl)-imidazoles, useful as fungicidal compounds, and their preparation, are described.

PURPOSE:A method for handling solid carbonaceous materials by dispersing a solid carbonaceous material, e.g. coal, waste plastics, waste tires, etc. in a heavy oil, an alkali metal compound, etc., and by efficiently gasifying the mixture.

Sintered silicon nitride articles are prepared by sintering a silicon nitride compact of a density of at least 1.3 g/cm3 in nitrogen gas atmosphere at substantially atmospheric pressure, while the compact is embedded in a protective powder comprising silicon nitride, boron nitride, or a mixture of silicon nitride and boron nitride, and one or more sinterization additives for silicon nitride, said ...

A heel holder for a safety ski binding having a sole plate which is secured to the ski by a locking member which is movable against the force of a spring. The locking member engages a holding member and the sole plate is secured adjacent its frontmost end against a vertical movement relative to the ski. In addition, the sole plate is pivotal approximately in the center thereof about a vertical axi...

A safety ski-binding having force transmitting surfaces which are inclined at an angle which corresponds substantially to the angle of friction. The force component acting in the direction of release of the sole plate created by the additional load compensates for the friction, so that the release resistance is not influenced even for a heavy load from the ball of the skier's foot even for the pur...
