Disclosed is a clarifier for use in treating a liquid containing non-soluble particles in suspension in order to separate these particles from the liquid. It comprises a tank, a liquid supply duct opening into the bottom portion of the tank and an injector for injecting a gas under pressure into at least part of liquid supplied to the supply duct in order to saturate this liquid with said gas and ...

For the continuous winding of indigo-dyed cotton yarns, the feed speed of the cotton yarn is set by the rotary speed of a previous feed unit (10). Changes in yarn tension are registered shortly before the fixed point (5) of the direction change, in the reciprocating yarn guide action, to be converted into a rotary speed change signal for the drive motor (8) of the grooved roller (7) which gives th...

A magnet sleeve (9) is arranged in a housing comprising a tube (2), lid (1) and base (7) to form a coupling surface (13). The sleeve is connected via a thread coupling to the base and comprises a peripheral opening (10) to allow adjustment of the characteristic. The magnet armature (6) is vertically moveable in the magnet sleeve.

Bracing strips or cords are wound on the belt (3) of a radial tire guided by a traverse (17) to produce a spiral layer. At least two electromagnetically operated retarding rollers (18) are placed so that they are contacted by the cords near the ends of the traverse to increase the winding tension.

A drive control system for a hybrid vehicle has an IC engine coupled selectively via a clutch mechanism to a drive train (4-18). The drive train is coupled to the electric motor (3). There is a drive device (17) to couple the IC engine (1) to the drive train in order to set the engine into motion by the control of the clutch mechanism in an operated state. The supply of fuel to the engine is stopp...

The invention relates to a thread transport device, comprising a transport surface (4) for conveying the thread (6). In order to prevent scoring during the thread feed, a grooved cylinder (10) is allocated to the transport surface (4) which guides the thread (6) back and forth in a transverse direction to the transport surface (4).

In the process for the production of welded can bodies from plastic-coated tinplate, the plastic coating is removed in the region of the side edges (8, 12) under the action of a laser beam and the tinplate, after being bent round to form a longitudinal seam, is welded together.

Inventions relating to the field of information technologies provide an appropriate account of "user's profile", i.e. user's information need, and supply a user with data about the content of the whole complex of processed information materials in a integrated form with a quantitative evaluation of relative covering, in processed materials, various components of "user's profile" both separately an...

A system and method are disclosed for separating particles having different sedimentation velocities. The system includes a fluid chamber for separating the particles from one another. Conduits are provided for flowing liquid carrying particles to the fluid chamber and for mixing the liquid with a diluting liquid. Structure is also provided for separating particles from the liquids after the parti...

Discrete sheets (16) are shingled to acquire lower speeds of material passage through a process application zone (20) of the system while maintaining overall system throughput rates when compared to conventional web systems.

The present invention concerns a process for forming titanium metal alloys directly from crushed titanium sponges or from powders. The process uses a low melting point bath containing bismuth, which allows the introduction under vacuum of titanium, as well as the addition of other elements and facilitates low temperature extrusion. The extruded semi-finish products then undergo degassing, grouping...

An apparatus to treat a sphincter, includes a support steerable member, having at its distal end two expandable members either contiguous or superimposed, one or both having a plurality of energy delivering means, one or both expandable members being porous or having perforations to allow the expanding medium, in the form of an electrolyte, to controllably wet the surface of the member and enhance...

Aliphatic polyurethane film forming mixtures, image bearing aliphatic polyurethane films, and image bearing retroreflective sheeting having such image bearing films are described. The image-bearing aliphatic polyurethane films of the invention comprise an aliphatic polyurethane film derived from a film-forming mixture comprising (A) an aliphatic polyurethane, and (B) at least one hydroxy-containin...

In order to provide a microprocessor based fault tolerant computing system, hardware counters or event monitors that are normally included on the microprocessor chips are used to count application instructions that are being executed by the microprocessors. By counting the instructions and preempting the execution of the application program after a predetermined number of instructions have been ex...

The invention is achieved by a polyurethane that is the reaction product of 4,4'-diphenylmethane diisocyanate (MDI), poly(oxyethylene)glycol (PEG), and 1,4-butane diol (BDO). The equivalents of each reactant in the polyurethane is 4:1:3. Polyethylene glycol 1450 is preferred. The amount of hard segment (made up of chain extender and MDI) is about 46 weight percent. The polymer is unusually tough a...

The poorly conducting tread rubber has an embedded, circumferentially-surrounding radial film layer. This contacts the road and e.g. reinforcement or other radially inner conductive portions of the tire. The film layer and portions have a specific resistance below 10<8> ohm.cm (i.e. they are good conductors in terms of static electricity potentials). The film layer is formed during manufacture, by...
