The method for removing interfering substances from suspensions by flotation involves decompression of a gas-saturated liquid separately, before it is introduced into the suspension containing interfering substances. Also claimed is an apparatus for implementation of the method. It comprises a separate decompression unit (4), a unit (2) for enriching a liquid with a gas, and a flotation cell (6).

The buyer (B) communicates with the control system (S) via email, enquiring about availability of a product. The control system then communicates with the producer (P) and the distributor (D) via email. If the goods are available, the buyer makes the purchase and the distributor confirms delivery data to the buyer via email.

An improved biodegradable controlled release system consisting of a polymeric matrix incorporating a local anesthetic for the prolonged administration of the local anesthetic agent, and a method for the manufacture thereof, are disclosed. The polymers and method of manufacture used to form the PLAMs are selected on the basis of their degradation profiles: release of the topical anesthetic in a lin...

In a process of separating a liquid sample having phase portions of different densities by centrifugal separation, a phase separator container is employed. The phase separator container comprises a housing having concentric inner and outer cylindrical walls defining a longitudinal axis and a top wall and further a piston body constituting a bottom wall of the housing. The piston body defines toget...

Closed feed guidance is afforded in the inside of the mill rotor (3) by spaced vertical grooves (7) for exchangeable grinding tools (8) sized at foot to fit the groove for their guidance. Alternating grooves (7) on the inside of the stator (5) or projections or recesses take the exchangeable grinding bars (6). The sectional area of the bars is that of a triangle as opposed to that of the grinding ...

A modular sleep system has a foundation unit, an support unit having an innerspring and a support surface covered with a friction material, and a comfort unit having compressible material encapsulated in a woven upholstery material which is engaged by the friction material on the support surface of the support unit to prevent lateral movement or sliding of the comfort unit relative to the support ...

The tungsten/heavy metal alloy is suitable for tools such as extrusion dies and extrusion mandrels for the hot-forming of copper and copper alloys. The novel alloy consists of 80 to 89.9% by weight of tungsten, 2 to 7% by weight of chromium, and a remainder of binder metal. The use of the novel alloy primarily results in a considerably reduced formation of grooves on the surface of the forming too...

A method of forming metal spheres includes ejecting a precisely measured droplet of molten metal from a molten metal mass, buffering the molten metal droplet to reduce the internal kinetic energy of the droplet without solidifying the droplet and cooling the buffered droplet until the droplet solidifies in the form of a metal sphere. An apparatus for fabricating metal spheres includes a droplet ge...
