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...

The valve consists of a strip -1- onto which two coplanar strips -3, 4- are welded separated by an opening -5-. Production of the valve takes a strip -11- onto which two strips -12, 13- are welded separated by a space -5-. The valve obtained -16- is welded onto a laminar -17-, which forms part of the inflatable, with a hole -19- which has to coincide with the valve opening -5-. Next the first shee...

The improved rotary cutter performs cutting by making a knife edge portion of a rotating disc-shaped knife (2) bite into a surface of a sheet (1) being successively fed. On the underside of the traveling sheet (1), a brush (4) consisting of rod-shaped brush elements is fixed on a backing table (3) between point A and point B over the entire region in the lateral widthwise direction of the sheet (1...

The machine (46) comprises a grinding device and at least one grading device (37). The lower side of an opening of a raw material (1) intake chute (2) is arranged on an installation surface beneath a height of about 170 cm. The treated products are discharged into at least two separate respective different particle size fractions (17-19). The flow direction can have a low construction height befor...

The equipment compares the actual acceleration of the vehicle on a slope with a reference value. The shortfall in power from the engine (10) is determined (106) with respect to the position of the accelerator pedal. The reference value of acceleration is reduced (108) by an amount which decreases with an increase in road speed (62) after the determination of power shortfall. A descent is recognis...

The blade (10) consists of a rotating cutter (12) with axially spaced knives (18), which mesh with a wider cutter (14). The wider cutter is a stationary comb (20), and the rotating cutter's axis (30) lies off this comb's plane. The rotating cutter may comprise a drum (22) on which the knives are mounted. The knives may be formed from a polygonal rod (24), and cut with their outside edges.

A system and method of separation of therapeutic components from blood. The system includes a dual member centrifuge and a disposable single use fluid transfer set. The set includes an elongated flexible separation chamber having an input port, a separated component output port and a residual fluid output port. The input port and the separated component output ports are located at opposite ends of...

A centrifuge separation device is disclosed and includes a rotor (12) configured to be connected to a centrifuge motor (19) for rotation about an axis of rotation (13). A retainer (14) is associated with the rotor (12) and defines a passageway (14) for a separation channel (44). A protrusion (48) formed in one of the passageway walls (15, 16) extends towards and is spaced from the other of the pas...

The present invention provides a method for making metal parts from metal powder compositions comprising an iron base metal powder and an amide lubricant. The method comprises the steps of compacting said composition, pre-sintering the compacted composition, compacting the compacted and pre-sintered composition, and sintering the recompacted composition. The metal parts have improved physical and ...

The present invention is a mechanically frothed foam that is prepared from a polyurethane formulation that includes both an organo-metallic catalyst and a tertiary amine catalyst. Foams of the present invention have low density and good physical properties, which make them desirable for carpet applications.; L'invention concerne une mousse que l'on a fait écumer mécaniquement et qui est préparée à...
