CONSTITUTION:An oil path P2 is formed with a recess 41d made in the innercircumference of tubular section 41c extending axially from the innercircumferential section of upstanding wall 41a of support 41 and a sleeve 42 fitted tightly to t...

The invention relates to a method for adjusting the foam surface height in a flotation cell. The invention is particularly well suited to flotation cells provided with a rotor-stator system, and especially to systems with several successive flotation cells and lines. The foam surface height (2) is regulated by adjusting the height of the chutes (5) or of the edge plates (9) of the chutes.

Heat-sealable and peelable film for polystyrene containers, consisting of at least one film comprising a mixture (a) of polystyrene, (b) of one or more copolymer(s) of ethylene and of acrylic derivatives. Also a process for sealing a polystyrene container by means of the said film and the heat-sealed polystyrene container thus obtained.

The invention relates to a method of monitoring the drilling of a borehole through an earth formation with a rotating drill bit fixed at the lower end of a drillstring. At least one physical quantity associated with the vibrations resulting from the interaction of the rotating drill bit with the earth formation is detected and an oscillatory signal is generated in response thereto. Filter coeffici...

A tissue gripping apparatus including a cylindrical member positioned about a tubular body portion or cannula. The cylindrical member includes a plurality of articulated arms that are movable between engageable and non-engageable positions. A hinge in the articulated arm enhances the tissue gripping abilities of the apparatus.

The multi-component system is suitable for processing by the Hatschek process and other processes known in the building material industry. It consists of natural polymers and PAN fibres composed of PAN structured shaped objects and fibres. The natural polymer/PAN fibres ratio is between 60:40 and 40:60, the water retention capacity is between 120 and 160%, the solid content is at least 26% and the...

Polymers with a high glass transition temperature are used in cement additives to produce a portland cement mortar or concrete that does not have the initial stickiness typical of prior art polymer-modified portland cement compositions and does not form a crust on the surface when exposed to air drying, thus improving the working time of the mix. This simplifies equipment cleaning and permits the ...

Calcium phosphate minerals are formed by using phosphoric acid source substantially free of uncombined water in conjunction with a calcium source, normally as any combination of carbonate, phosphate and hydroxide, and, as required, any additional base to neutralize the phosphoric acid. Protein may be optionally added. The resulting product is readily formed and then sets to a hard, stable, workabl...

A method for purifying water containing pollutant mixtures is described, which uses a reactor containing a semiconductor as reaction catalyst and a lamp which emits radiation having a wavelength of less than 400 nm The reactor, characterised in that its walls allow water and the pollutant substances to pass through, is immersed in the water to be purified so that the pollutants contained in it rea...

This invention relates to a method and an apparatus in the recycling of plastics, by which it becomes possible to handle and to take care of the materials in a plant without preceding sorting into different kinds of plastic. After a possible coarse sorting for removing foreign materials the waste plastic is supplied to an apparatus (5) for disintegration and washing with water containing a grease ...
