A process for the production of iron from ferrous raw materials in a converter containing an initial iron smelt into which at least fuels, oxygenous gases and ferrous raw materials are introduced during the production phase, the reaction gases being afterburned with oxidizing gases in the gas space of the converter above the smelt and the resulting heat transferred to the iron bath, and a partial ...

Masterbatches comprising high density polyethylene (HDPE) are used for the production of polyolefin articles, particularly films. Employing HDPE in a masterbatch alone or in combination with a hydrocarbon resin and/or a polyolefin ultimately results in extruded polyolefin articles of optimal stiffness and ductility. Employing a high density polyethylene in combination with a hydrocarbon resin and ...

A three component refrigerant composition for use in vapour compression refrigerators and avoiding the use of ozone-depleting chlorofluorocarbons comprises a three component mixture of: (i) a major portion comprised of chlorodifluoromethane (R22) or pentafluoroethane (R125); (ii) R125 or octafluoropropane (R218); and (iii) propane in non-flammable proportions. f

The invention comprises a tunnel-type heating furnace of modular construction for heating glass sheets carried therethrough in succession on a series of aligned rollers. The furnace enclosure includes a lower section of generally rectangular cross-section beneath the rollers and an upper section, which is of generally elliptical configuration in cross-section, above the rollers. The upper enclosur...

A leadfree plate-shaped roof flashing material comprises a sandwich structure in which a stress damping and stabilizing layer (1) of ductile material is completely covered on one side and at least partly covered on the other side by preferably metallic foil sheetings (2, 3), e.g. of aluminium foil, designed with densely positioned flattened folded sections (4) having such a form, e.g. as closed in...

The proposed method of treating fluid mediums involves treatment of the medium in question in a rotary-pulsation device, the medium being subjected to the additional acoustic action of the stator in the form of oscillations of varying frequency and amplitude; the frequency is varied by altering the rotor speed, while the amplitude is determined by the moment of inertia of the revolving rotor. The ...

Absorbent structures having a fluid acquisition/distribution layer with an average dry density of less than about 0.30 g/cc, an average density upon wetting with 1.0%, NaCl aqueous solution of less than about 0.20 g/cc, and an average dry basis weight from about 0.001 to about 0.10 g/cm2; and a fluid storage layer positioned beneath the acquisition/distribution layer comprising at least about 15% ...

A rigid wall partition system (2) which is vertically upwardly movable into storage position and vertically downwardly movable to form a continuous wall. The system comprises a plurality of panels (8) secured to members which in turn are pivotally secured to spaced trains (20) of single pantographs, contraction of the pantograph causing the panels to fold, in accordion fashion and expansion of the...
