A cyclonic froth flotation cell, suitable for use in the separation of minerals comprises concentric inner and outer cyclones (2, 4). A liquid feed containing particles and injected dissolved air is fed tangentially via a conduit (7) into an inlet chamber (7a) below the outer cyclone and in communication with the inner cyclone. On contact with a stator (10), bubbles are generated which form a frot...

With the creel for a spinning machine according to the invention at least two rows of rotatably suspended roving bobbins, which extend essentially in parallelism with respect to one another, are adjacently lined-up. Normally in ring spinning machines there are employed for such creels roving deflecting rods which extend horizontally in the longitudinal direction of the ring spinning machine. The r...

In the manufacture of flexible polyurethane foam from a polyol having at least two reactive hydrogen atoms as determined by the Zerewitinoff method, a polyfunctional isocyanate and a blowing agent using a polymerization or gel catalyst and a blowing catalyst the blowing agent comprises water and from 10 to 90% of methylene chloride, the polymerization or gel catalyst is chosen from organic and ino...

The present invention relates to a seal for a rotatable therapeutic catheter, such as a motor driven therapeutic catheter. The seal is made of a drive shaft which extends through an elongated bushing. The combined drive shaft and bushing form a low-friction axle/bearing combination such that there is little friction between them. In addition, the long restrictive path between the drive shaft and t...

PURPOSE:To prevent the damages of a photodetector by a retreat as well as to confirm the piercing completion by positioning a retreating photodetector beneath the material to be worked after the piercing with a laser beam irradiation of the material to be worked and by detecting the complete passing with the laser beam for maeasurement. CONSTITUTION:A piercing with irradiation 18 is performed with...

In the tyre-building apparatus, the tyre tread rubber is transferred to the tyre-building drum from a fixed support, advancing in the same direction as the drum rotation. In order to ensure that the tyre camelback tread rubber is properly laid in place, even when tread rubbers which vary from one another in their dimensions have to be used, the invention provides for the diameter of the tyre-build...

A large sunshade such as beach and garden-umbrellas which is formed by independently openable sectors, the opening being carried out by lifting and placing in the open position the ribs (3) after one another. To this end, rib struts (5) are hinged to a fixed intermediate point of the rod (1) and each strut has an intermediate articulated connection (16) forming two strut arms (5a, 5b). Each pair o...

A pigmented thermoplastic polymer masterbatch composition comprises a polyester of melting point above 200 DEG C. based on polyethylene terephthalate, a second polymer to plasticize the polyester, and pigment in an amount of at least 20 parts per 100 parts of composition. The second polymer can be also a toughening agent for the PET and can be a polycarprolactone, or a copolymer of ethylene with ...

An apparatus for and a method of detecting tears in a conveyor belt (1), wherein a light emitter (6) is positioned facing one surface of the conveyor belt (1) and a light receiver (7) is positioned in alignment with the light emitter (6) and facing the opposite surface of the belt (1). Where there is no tear in the belt, light from the emitter (6) will be occluded from the receiver (7). However, w...

1. Apparatus for determining oxygen concentration in gases, liquids and tissues by measuring the decrease in light emission of a luminescent surface (Fst) with an excitation light of a certain wave length comprising a light source (L) for producing the excitation light and a device (F2 , PM) for measuring the intensity of the emitted light, characterized in that the surface (Fst) is the surface of...

A web of gray cotton fibers is entangled by passing it under a series of low pressure liquid jets which are oscillated in a direction transverse to the direction of travel of the web. The entangled web is then subjected to a cotton bleaching step, and then dried, to produce a coherent nonwoven fabric that requires no resin binder.

Resilient foam particles and moldings are obtained employing a lightly crosslinked polymer such as a styrene polymer with volatile fluid foaming agent that has low permeability through the polymer. Multiple expansion will permit low density particles for molding.

The solid fuels are gasified in a fixed bed under a pressure of 5 to 150 bar with gasifying agents containing oxygen, steam and/or carbon dioxide. The incombustible mineral constituents remaining during the gasification are tapped as molten slag. Pulverised and fine-grained fuel is injected by means of a carrier gas into the lower region of the fixed bed. The pulverised and fine-grained fuel has a...

Iron is recovered from an iron-containing dust obtained in processing iron or steel by dissolving iron and bivalent metals present in the dust in an acid. Subsequently the iron is precipitated as iron hyroxide by adding an alkaline substance or ammonia to adjust the pH to 5 to 8. Before or during precipitation of any iron the bivalent metal ions present, such as zinc, cadmium and lead, are convert...
