Method and apparatus for the production of metal granules from a molten metal are disclosed. A molten metal stream (19) is directed against an impact element (8) located above the surface of water in a water tank. The impact of the molten metal upon the impact element causes the molten metal to disintegrate into drops (20) which spread out radially from the impact element. The drops fall down into...

Flexible foam is prepared using 1,1,1-trichloroethane as the sole or predominant auxiliary blowing agent.

Date Nov. 17, 1988.A device for adjusting the seat height (S) of a chair (2) comprising four leg extenders (A, B, C, D). Each has an aluminum extrusion leg extension member (11) with a rebate (12) for partially accommodating a leg (1) to be extended. Located at one...

The present invention relates to a method and a means for atomizing liquids, such as metal melts in which a tapping stream (6) of the liquid encounters one or more media jets (9), e.g. gas and/or liquid. The mixed stream obtained is directed towards a barrier (10) with the object of achieving effective dispersion of the liquid in the media, i.e. atomization.

Foundry moulds or cores are made by a method comprising mixing a granular refractory material with a potassium alkali phenol-formaldehyde resin binder solution, forming the mixture and curing the formed mixture by gassing with a 1-3C alkyl formate. Cure by gassing with a formate, particularly methyl formate, enables rapid and efficient production of foundry moulds or cores. The formates used have ...

A cross-country ski binding for cross-country ski shoes which have, at their front sole end, engagement elements which correspond with and engage into engagement elements of the ski binding, to provide a pivot connection. The ski binding has a U-shaped clip or stirrup member for securing the front sole end against lifting off the ski binding engagement elements, the legs of which clip are mounted ...

PURPOSE:To simply set holding force against a gold wire by adjusting elasticity of a compressed coil spring by an adjusting screw. CONSTITUTION:With a gold wire 2 held by a movable arm 3 and a thin plate arm 6, the thin plate arm 6 is pressed by a compressed coil spring 13 and the gold wire 2 is elastically held by both arms 3 and 6. This elasticity can be set to a specific value by adjusting scre...

PURPOSE:To obtain a fine superconducting thin film pattern by preparing solution containing organic acid metallic salt and processing an organic acid metallic salt thin film, which is formed by drying after application of said solution on to a substrate, by heating. CONSTITUTION:An aqueous solution of organic acid sodium and an aqueous solution of metallic nitrate are mixed by stirring and sedimen...

Process for contacting particulate solids (e.g. cracking catalyst) with a fluid (e.g. a hydrocarbons-comprising mixture) by introducing said fluid as a, preferably single, annular stream into a stream comprising the particulate solids. The invention further relates to an apparatus for contacting particulate solids with a fluid comprising a solids container (e.g. a fluid catalytic cracking riser re...

A sheet made of a transparent plastic material comprising a layer of polyurethane formed by depositing, by casting or reactive spraying on to a horizontal support plane of a reaction mixture comprising a polyol component and an isocyanate component, the face of the polyurethane layer which was facing the support during the formation of the layer comprising an acrylic polymer resulting from bringin...

The control manifold comprises a manifold casing which is at least approximately hexagonal, a pair of parallel sides forming thereby the upper and lower narrow sides of the casing, between which, the internal-casing conduit section of the connecting piece for the vacuum pump and for the pressure-medium supply container extend vertically and approximately concentrically; the conduit sections of the...

In the automatic control of a motor vehicle friction clutch (1), the clutch is disengaged when the vehicle is stationary and thus, despite the fact that the engine (3) is running and the gear is engaged, the driver can leave the vehicle. In the case of a fault of the clutch system causing engagement of the clutch, the vehicle may set itself in motion. This is prevented by an arrangement in which, ...

A differential gear unit includes a viscous coupling for restricting the differential rotation of output gears (27, 29), with the conneciton of one of the parts (31) of the viscous coupling to one output gear being by way of a releasable connecting device so that the viscous coupling can be brought out of operation when required, e.g. under vehicle braking. The connecting device comprises a sleeve...

The infrared sensor (10) mounted on the rear of the vehicle monitors cone shaped sensing field and operates a cut-out relay (23) to switch off the engine if a person enters the cone. The sensor is powered from the reversing light circuit (14) and requires no additional supply connections to the vehicle electric system. The sensor (10) is fitted at the height of the rear light cluster and can be al...

Defects in the emulsion layer of a photomask are repaired by irradiation of the defect with UV light in a shape to match the defect and by destroying the defect by this treatment. The UV beam of an excimer laser is used to pass through an aperture of suitable configuration. To correct a black spot defect (D) of the emulsion mask (7), the beam (2) of a laser oscillator (1) is expanded (3) and the ...

Cast film on the basis of low-density polyethylene is prepared by extruding the molten polymer at temperatures of the melt at the die gap of below 200 DEG C. Films that have been prepared this way have special mono-axial orientation as a result of which the mechanical properties are improved.
