A method of forming a foamed slag on a stainless steel melt in an electric furnace involves introducing, into the slag, a powder containing metal oxide and carbon which react to form bubbles of the reduced metal vapour and carbon monoxide and thus create a stable foam. The metal oxide is an oxide of a volatile metal, especially zinc or lead, and at least part of the powder is dust from an electric...

A piezoelectric device (1) includes an at least locally thin-walled ceramic substrate (2) and at least one piezoelectric transducer (3) formed on the thin-walled region (2a) of the substrate. The transducer (3) is film-shaped and has a convex shape to protrude toward the substrate (2).

The device (10) comprises a container (11), closed by a lid (14), for holding the lubricating fluid; a strip of felt or the like is immersed in the container and becomes impregnated with the fluid by capillary action. One end of the strip protrudes from the lid of the container (11) and wraps around a cylindrical support so that a respective portion (13a) of the strip (13), shaped like a cylindric...

The multistage milling machine uses gas eddies to comminute the material. The mill has a cylindrical stator (3) with a vertical shaft (1) on its centreline carrying the rotor. A feed device (15) at the top and an outlet (14) with a screw conveyor at the bottom. A carrier gas may be introduced through a passage opposite to the passage containing the screw conveyor. There are a large number of ident...

The medical system (1) comprises at least one guide (2, 2', 2") and a medical instrument (3, 3') with wheels (10), adjustable relatively to an object (P). At least one guide element (11) works together with the guide, and an adjustment arrangement (22) causes, that the medical instrument is adjustable through the guide element on the guide, relative to the object and/or on the wheels. The guide is...

A sealed lead-acid cell is provided with an internal cell restraint (36) which contacts the interior surface of the cell cover (14) and is positioned between the positive plates of the cell and the cover (14), the internal cell restraint (36) cooperating with an external cell restraint (50), such as a plastics coated metal face plate, to direct positive plate growth which occurs in service away fr...

A device for controlling the production quality of a press, which manufactures package blanks from a sheet of material by transferring the sheet of materials, such as paperboard or corrugated board, chronologically through an infeed station, a die-cutting station, a waste-stripping station and a delivery station, has an arrangement for controlling the printing and blanking quality which includes a...

There is described a diagnostic system comprising a desk-top, flat-bed optical colour scanner (101) which scans a substrate, such as a urine stick (107), which has been dipped in a container of analyte (105). The substrate (107) carries an image result generated by a chemical diagnostic assay and the scanner (101) generates a digitised record of the image. A personal computer (103) coupled to the ...

PURPOSE:To facilitate the change of assembling work by composing a socket to be attached/detached in a circumferential direction for separating work processes properly, and improving the design of a multi-stage signal display lamp by lowering height per light source unit. CONSTITUTION:A chassis 51 on which a socket A having a diagonally installed bulb 1 is inserted and supported to be freely attac...

PURPOSE:To prevent crystallization of an element and to maintain an amorphous state stably by forming thin films of a luminescence layer and an electric charge conveying layer through light irradiation in the manufacture of an organic electroluminescence element. CONSTITUTION:Vacuum deposition of an organic material on a glass substrate 26 is carried out under a set condition while a sample 15 is ...

A posted-write queuing program for writing information sectors to disk sectors includes error-handling routines to minimize the risk of data loss upon specified types of errors. Upon timeouts, queuing is suspended and all information sectors pending in the queue are written out to the corresponding disk sectors. Upon specified types of write errors, queuing is discontinued and repeated attempts ar...

Formulation comprises a particulate medicament (I) e.g. salmeterol, salbutamol, fluticasone propionate, becolomethasone dipropionate and a fluorocarbon or hydrogen-contg chlorofluorocarbon propellant. Also claimed are the prepn of the surface-modified medicament and a canister for delivering metered doses of the aerosol formulation. Pref., (I) is salmeterol xinafoate (Ia); salbutamol sulphate; flu...

An improved spandex composition is provided in which a polymeric hindered tertiary amine stabilizer is present. The polymeric amine is poly(diisopropylaminoethyl methacrylate/hydroxybutyl acrylate) or poly(diisopropylaminoethyl methacrylate/ethyl acrylate).

The agricultural machine such as a tractor has a guidance system so that a track (6) may be followed. Mounted on the tractor is a carrier arm (1) for a number of sensors (3). The arm is positioned over the track and is adjusted by an actuator (5) via a linkage. The sensor outputs are used to control the steering so that the machine follows the track.

An endoscope treatment tool makes it possible to accurately direct a distal end driven part provided at a distal end of a sheath to a diseased part. The sheath is formed into a rotation follow-up structure such that rotation produced at its proximal end side is transmitted to its distal end side. The sheath and an operation wire are non-rotatively connected to an operation part.
